Since the waste of energy-saving lamps contains mercury, it is very harmful to the environment. Foreign countries also attach great importance to the recycling of energy-saving lamps. The US Environmental Protection Law stipulates that the original owner of the waste is always responsible for his own waste, so that the treatment of high-intensity discharge lamps is also mentioned on the agenda. The American Pioneer Company has established a recycling treatment plant for waste high-intensity discharge lamps to treat waste high-intensity discharge lamps for consumers at the expense of new lamps. Japan is the country that has done the best in the recycling of fluorescent lamps. It can handle waste batteries and waste fluorescent lamps in Hokkaido. The collection method is 93% collected by private environmental organizations and 7% collected by various manufacturers. Recycling in Sweden and Germany is based on two parallel recycling channels: sales system recycling and community recycling. Seven states in the United States prohibit the use of energy-saving fluorescent bulbs directly in conventional garbage bags. In other states in the United States, waste energy-saving fluorescent bulbs are disposed of at specific times throughout the year.
Incandescent lamp:
Incandescent lamps are also known as light bulbs. When illuminated, a large amount of electrical energy is converted into heat, and only a very small portion can be converted into useful light energy. The life of an incandescent lamp is typically 1000 hours.
Fluorescent light:
Fluorescent lamps are also called fluorescent lamps. The fluorescent tubes are made of mercury atoms that are emitted by the gas discharge process. About 60% of the energy consumed can be converted to ultraviolet light. Other energy is converted to heat and has a lifespan of around 2,500-3,500 hours.
Energy saving lamp:
Energy-saving lamps are also called compact fluorescent lamps, which have high luminous efficiency (5 times that of ordinary light bulbs), obvious energy-saving effect, and long life (eight times that of ordinary light bulbs). It works in much the same way as fluorescent lamps. Generally, under the same wattage, an energy-saving lamp is 80% more energy efficient than an incandescent lamp, and has an average life of 8,000 hours.
LED light:
LED lights, also known as light-emitting diodes, convert electricity directly into light. The heart of the LED is a semiconductor wafer. LED lamps have many advantages such as small size, low power consumption, long life and no mercury pollution. The life of good chip LED lamps is up to 100,000 hours.
SMA means surface mount assembly. It is a new generation of electronic assembly technology, which compresses traditional electronic components into a device with a volume of only a few tenths.
Surface mounting is not a new concept, it is derived from earlier processes, such as flat mounting and mixed mounting.
For the assembly of electronic circuits, a point-to-point wiring method was initially adopted, and there was no substrate at all. The packaging of the first semiconductor device uses radial pins, which are inserted into the through holes of the monolithic circuit boards that have been used for the packaging of resistors and capacitors. Active components have been widely used in the past ten years.
