On the afternoon of March 20, 2008, Aladdin Lighting Network had the honor to invite Huang Guangmin from Guangzhou Guangheying Lighting Technology Co., Ltd. to come to the company for a face-to-face interview with netizens.
Mr. Huang Yumin and Aladdin Lighting Network reporter Chen Xiaohang Aladdin Reporter: (hereinafter referred to as reporter) Huang Zong, good afternoon! You are very welcome to visit Guangya-Aladdin Lighting Network.
Huang Yumin: (hereinafter referred to as Huang) Thank you, Guangya for giving me this opportunity.
Lighting design reflects aesthetics
Reporter: With the development of society, nightscape lighting has become an important part of urban construction. What lighting design techniques do you think can be used to reflect the structural mechanics and aesthetics of modern architecture?
Huang: Modern architecture is developing faster and faster. Nowadays, lighting, aesthetics and color have a new feature. Therefore, there may be some new improvements in the performance of the building. Traditionally, we have used floodlights, LEDs as outlines, and neon lights. Now, we have introduced more new technologies, including some stage lighting, as well as some dyeing, etc., mainly to show people who have a lot of feelings in the different states of the building. So the building becomes a living body. Architectural lighting is designed to match the vitality of the building, not to be as good as it used to be. To express architecture is to tell people what the building represents, that is, a breath to convey, is a functional extension of the building. So now more and more attention to architectural lighting.
Reporter: In urban night lighting, the application of floodlight is very extensive, but according to some data, the application of ordinary floodlights will have some defects. Is there a better product to replace it?
Yellow: Floodlights have been used for a long time. In the past few decades, urban night lighting has always been dominated by floodlights. However, with the increase in the structure of the building, including the glass curtain wall, the building is getting higher and higher, etc., the use of floodlights for night lighting is relatively power-hungry. Therefore, we will use a variety of forms, such as combining LEDs, combined with other new types of lamps, etc., and there are many ways of expression. Modern architecture, it needs to tell others a concept that needs to give others a feeling. We see a building is a feeling. Therefore, different buildings should be applied in different forms. Floodlights may be a good source of light. Now there are many new forms of expression, including LEDs, fiber optics, and controls.
Light and shadow produce artistic light
Reporter: I know that your company has a product that is an art mixed light. What is the design concept of the art mixed light? How to reflect lighting and art?
Huang: Modern architecture requires a variety of ways of expression, and different expressions are needed in different situations. Therefore, we designed this art light, which reflects the feeling of enjoying the light. We have had the idea of ​​"mixing light" for a long time, about five or six years ago. After we got this idea, we did a lot of work and constant testing in order to make the light feel. We found that this feeling can be appreciated. One of the most important principles we use is the contrast of light, which can produce a variety of shapes in order to produce something that people can see. If there is no contrast between what people see, it may be a black and white, monotonous thing. So we think that light can not do some comparison. From this concept, we found that by using two different optical systems, we can find some contrast between light and light. In this contrast, we suddenly found some wonderful effects. After we slowly explored, we found that light itself is a work of art. So, when we took this product out, the market and experts recognized us very much, including the chairman of the IALD International Lighting Designers Association. In the past few decades, this industry has not had such a breakthrough, which is a breakthrough in the application form of light. We are still very pleased to be able to provide designers with a new way of expressing the beauty of architectural art. This way allows light to express and strengthen the power of the building. There are many combinations of our products, and the combination of these can produce a variety of novel effects.
Reporter: The art of mixed light is made using the design concept of light and shadow, then how is it realized optically?
Huang: The principle is not too complicated. We use a different set of rays to superimpose to produce some reactions. For example, the spotlight produced by the spotlight is optically superimposed with the floodlight, in addition to the superposition of colors, and the superposition of energy. The color it produces is a comprehensive color. New combinations of different colors will appear. It can be changed into thousands. Its variety can adapt to the needs of different scenes, and its performance is quite rich. Ordinary floodlights do not achieve this effect.
Reporter: Art light is a new model in optical applications, so what is the relationship between light and shadow?
Huang: This is the core thing. When we see whether a picture is beautiful or not, there are various contrasts, including contrasts between light and dark. If there is no obvious contrast between light and dark, just see one. The art mixed light, in addition to the contrast between light and dark, adds contrast to hue, lightness, chroma, and color.
Reporter: The history of art mixed lights and comparison with ordinary mixed lights?
Huang: The art of mixed light has just been put into production all over the world. It is a very innovative thing and a new mode of optical application. It is a new concept and a new artistic means. It is convenient for designers to apply our fixtures. He only needs to understand our light and see some of the choices we give him. He can choose this kind of luminaire according to the feelings that the building wants to express, rather than being monotonous like other practices. This is a new way. There are many ways to express a building, assuming that it is necessary to use light to beautify the building. This is one of the means to give people a new feeling.
Reporter: What do you think about the situation that the domestic building floodlight field only pays attention to the price and does not pay attention to quality?
Huang: This may be because the customer or the owner has not understood that light is an important element. Many architects now have a poor understanding of light. They have not yet realized the importance of light for architecture and for the interior. The whole society is not aware of the importance of optics. For example, optics will bring some feelings. He didn't feel it, so he couldn't pay attention to it. At present, foreign countries are paying more and more attention to lighting design, including domestic, and their trend is to pay more and more attention to lighting design. When the art of lighting is valued in the future, the lighting division will receive more and more attention. The ideas they put forward will be accepted by others. Another reason may be that the design itself has problems, that is, the building is not well represented in an innovative way. If you still use a very common way to do an effect, it may make the owner feel ordinary, so that your design concept can't move him, it may affect their attention to the lighting, but also affect their aspect. Input. To give a simple example, the beauty of the heart is there. If you spend money on activities, it will cost a lot, but if you use the money to make lights, you can be beautiful for a whole year. The cost of lighting the owner's investment is only about 5-10% of the total construction cost. In recent years, as the lights have been gradually valued, these problems have only been partial or one-sided, and it is some difficulty in the advancement.
Reporter: Since the relationship between light and shadow is so close, it can be seen that the art mixed light is a combination of technology and aesthetics. Today, when promoting energy-saving and brand-reduction, this lighting festival is not energy-saving. What is the principle of energy saving?
Huang: Our lamps are very energy efficient. We have done a long time of research, in fact, the power of our lamps is not very large. Our luminaires have only two main powers, 70 watts and 150 watts. Even when combined, the maximum power is no more than 300 watts, while the small power is only 100 watts. We are able to achieve such low power, which is different from the traditional spotlights. Conventional floodlights need to be adjusted to match the projected area. Therefore, it is impossible to install it against the wall. If installed against a wall, the highlight is very high, while the other areas are very dark, it becomes a glare from the light, and the place away from the light is very dark. Therefore, an ordinary floodlight should be installed at a considerable distance from the projectile, but it costs electricity. The narrow beam part of our luminaire, 70 watts can reach more than 30 meters, the optical control is very good, it seems that there is only one beam, but it actually has four sets of beams. A set of beams can push the beam to a height of three to five meters, and a group of beams is pushed to a height of more than thirty meters. In other words, this light is not simply a traditional approach, it has some changes. There is a transition to this change, and this transition brings an artistic feel.
Reporter: Netizens don't know much about art light mixing lights. Is art light mixing a concept? Please tell us more about it.
Huang: It is a process of changing from a concept to a product. In order to do this well, we have done countless experiments and tests, the purpose is to bring the feelings out. In order to do this spotlight well, we used a lot of testing methods and found many manufacturers, but found that there is no way to achieve it in China, so we directly use some foreign technology and products to do the spotlight. We found that there can be many different expressions. At first, we used a cup that was more concentrated than this, and found that it was not the best. Several sets of optical systems make the poly cups very concentrated, gathering only four to five degrees. Its light becomes a line and there is no feeling. We need to have a transition that requires a change in the area. This change is very delicate and can only be felt by careful observation. Our lights give a new feeling. The art mixlight gives a few feelings: first, dazzling. Second, look good. People are fascinated by watching and will slowly appreciate this feeling. People will find that the building has aura through “stained with lightâ€. In the process of application, I think someone will slowly like this kind of lamp.
Reporter: How many watts can an art dim light reach?
Huang: At present, the maximum power of the art mixed light is 300 watts, two of which are 150 watts. In fact, one of the light sources can reach 250 watts, and the art light can go to 400 watts. If you reach 400 watts, there will be another feeling. It may be glaring. It may be very strong, but I don't think it is at its best. If you want to make this power, you may have to make some optical improvements. If you have the opportunity, we will introduce this power product. In fact, our product does not reflect its advantages through power, mainly through expression.
Art mixed light and LED have their own advantages and disadvantages
Reporter: In terms of cost-effectiveness and effectiveness in the market, what is the comparison between LED high-power and art-mixed lights?
Huang: High-power LED is actually a new product. The light of the LED is difficult to control due to the different angles of its illumination. In fact, we are constantly experimenting, because our technology also covers the practice of LED. We have done this test. It is impossible for LEDs to make our effects. And its power is very low. At present, the efficiency of LED illumination is not high. Its power is not going up, and the effective light that can be utilized is very small. Moreover, the distance cast by the LED is limited, and the surface brightness is high, but the actual number of lumens emitted is not high. Even if its power is done, its light-emitting area is large. It is difficult to achieve precise control when the luminous surface is large. LEDs are used for dyeing or for point source contours. But for the art of mixed light, we did not find a good solution. The light from the LED is emitted from the front, and it is difficult to precisely control its light, because our light is all designed with a computer. If the LED bead is to be large, its luminous surface is large and difficult to control. The light of the LED goes to the front, and the light from the source point of the art mixed light is emitted from the side, so the optical control is different. If you want to make the front light into a narrow beam, you can use the lens method, but the lens method has disadvantages. The light it produces is not beautiful, its spots are not transitional, but piece by piece. With our approach, it will add a lot of extra light, and it is a big problem to find a way to control these lights. To achieve the effect, this LED approach is still not suitable.
Reporter: In the outdoor lighting design, what is the difference between your lighting and LED lighting applications?
Huang: LED has a characteristic, its color saturation is very high, because its color rendering is very low, it can be said to be 0. Its color saturation is so high that it is difficult to express the original color of the building. Also, the surface brightness of the LED is high. If we want to observe the structure of a building, LEDs are placed on the surface, and it is difficult to see the structure of the building. The building may become a support frame, and the LED is the protagonist. What we are seeing is the change of various patterns and LEDs, but it is difficult to carefully understand the building itself. In addition to the change of colored color phase, the art mixed light can not be separated from the traditional floodlight form, so that we can appreciate the detailed structure of the building. This is the difference with LED. Different buildings need different ways of expression. If all the buildings are made with LEDs, you don't need to appreciate the buildings. Art mixed lights are still classified in the traditional spotlight type, and LEDs are still new. LED control is more convenient, its form and usage are different, so they are lamps of different performance types. If the building needs to be beautifully flashing like a firework, then LEDs can be used. If you want to express the details and structure of the building, the art mixed light has considerable performance.
Reporter: Will LEDs be applied to your company's products in the future?
Huang: I think there should be such a possibility in optical control. However, we contacted the suppliers of LED technology at home and abroad, and have not found a suitable LED light source for the time being. We will work hard in this direction, but in the short term I don't think there is such a product.
Reporter: Is the LED illumination, color rendering, color failure, cost and other issues solved?
Huang: In fact, these are big problems that are confounding LED development and belong to the direction of LED development. In the 1930s, there were LEDs. Why was it so hot in the 1990s? After decades of brewing, its cost, technology, etc. are all improving, and its brightness is also increasing. So it can go to this step today. However, so far, in the years that can be expected, it is too early for LEDs to replace traditional lighting. This is because it has many technical obstacles and unstable performance, such as light decay, heat dissipation, color drift and so on. Its color rendering is not very good. Its technology takes a long process to stabilize. Now using LEDs for engineering will find many practical problems, including hue, color decay, illumination, etc., and the impact is still very large. If the LED is to be powerful, it can achieve high luminous efficiency in an instant, but it will last for a short time, and its color change will be very fast. These factors are very complicated, I think it is not mature enough in just a few years. However, the actual application will mask some of its practical shortcomings. It takes time to solve these problems. If there is a chance, it can be solved.
Reporter: Can you explain the difference between LED and art light by the principle?
Huang: LED is a pure light source technology. It is only used as a light source. The art of mixed light is to use light to interpret an image, to tell people a feeling, is a way of expressing light and form. This is two things. From the product point of view, the art of mixed light with 70 watts of power can reach more than 30 meters, LEDs with 70 watts of power may be within a few meters and very dim. Moreover, the high brightness of the LED surface will affect the human vision, it is difficult to see the outline and structure of the building, and only some bright spots of light can be seen. The building turned into a beautiful pattern, but the details of the building could not be seen clearly. LEDs are actually very good and can be contoured, but some locations still require a spotlight to match. LED and art mixed light still have the opportunity to cooperate. Designers need to be familiar with them. LED and art mixed light are just different ways of expression. Both users and designers need to understand how the two are combined to be the best, in order to make a good work. A building can use only one method of expression, or both methods can be used at the same time.
Photo explanation
Reporter: Can you introduce us the photos you brought?
Huang: The principle of artistic light mixing is this: a narrow beam in the middle, then a wide beam, which contains many contrasting components. Including the contrast of light color, the contrast of light and dark, and the contrast of hue. There are several sets of beams inside, and these contrasts are achieved inside. We have spent a relatively long time doing this.
Mr. Huang Yumin introduced relevant pictures
This is a very concentrated optical system with its floodlight system. The degree of protection of the luminaire is IP66. In addition to the artistic effects, our lamps have two sets of light sources, so the requirements for the heat dissipation system are very high. The reason why we have been doing research and design for such a long time is actually to consider the heat dissipation. Among them, the V-shaped structure, in addition to its good appearance, has the function of heat dissipation and meets the requirements of thermodynamics. Due to the high heat dissipation requirements, it requires a certain volume to meet the heat dissipation requirements. The light box parts are separated for heat dissipation. We move the center of gravity of the luminaire to the center to reduce the swing. And our nut has a special structure, the screw and nut are tightly combined to ensure the consistency of the effect. Installation is also more elegant, with special accessories, is customized, easy to use. Our lamps have passed CE certification.
Mr. Huang Yumin introduced the contrast between art mixed light and other lamps
Usage and contrast of artistic floodlights and floodlights: Traditional floodlights can be projected against a wall, but the distance it projects is limited, so parts of the area are very dark. If projected against a wall, highlights can affect vision and are not artistic. If you put the luminaire farther away, the projection area becomes larger, but it has more harmful light, which reduces efficiency and is not artistic. The practice of narrow beam is beautiful, but the bright place is too bright, the black place is too dark, and the contrast is too strong, which affects the artistic effect. The art streak light compensates for some of the shortcomings of the scene just described. It complements the surrounding area, highlighting the brightness of the artistic effect, and has a gradual process. The extension of the side light weakens the contrast between light and dark, giving the building aura.
Mr. Huang Yumin introduced the actual engineering effect of the art mixed light
Energy-saving problem: In actual engineering cases, 70 watts for narrow beams, 70 watts for wide beams, and 140 watts for two lights. On the other side, four sets of 1000 watt lamps were used. That is to say, 4000 watts were used here. I used four 140 watt lamps, only a few hundred watts, so it was very energy efficient.
Reporter: The maximum wattage and range of art blending?
Huang: The maximum wattage can be two 150 watts, which is 300 watts. If you want to be bright, you need to improve the light distribution. The 70-watt spotlight has a range of more than 30 meters. The luminaire below is 150 watts. Actually, this luminaire uses only 220 watts, so it is very energy efficient.
Reporter: What is the difference between LED high power and art mixed light?
Huang: LED is a good lighting fixture. The usual practice is to use the building as a support frame and place the LEDs on the outlines and nodes to make the image an easel. LEDs can be patterned or discolored to turn the building into a screen. Its expression is to let people see the picture. The art of mixed light is the effect and feeling of people seeing the building and expressing light. One is gorgeous, the other is performance detail, and the two are different. Can't say that you are so bad, you can only say that what they express is different.
Reporter: I am very grateful to Mr. Huang for coming to Guangya-Aladdin Lighting Network for an interview. Please talk about the evaluation of our website.
Huang: Aladdin Lighting Network is doing a good job, I hope that you will get better and better.
