Waterproofing is one of the most difficult problems for outdoor lighting fixtures. Statistics show that high-power outdoor lights have a water leakage rate of about 2-3% within one year, and many international brand lamps are not spared. After three months of research, analysis and practice, the personnel of the R&D center of the wave of the passengers of the wave of passengers have made a ç¬ -type lamp 鳃, which can completely solve the problem of leakage of the outdoor lamp.
Respiration of the lamp
At present, most of the outdoor high-power floodlights on the market have IP65 protection, that is, six-level dustproof (small dust) five-level waterproof (anti-storm), in which the waterproof quality is quite different.
According to common sense, the performance of the lamp sealing performance has a great relationship with the leakage. However, it is not that the airtight lamp does not leak water. The test of the Kyrgyzstan wave passengers shows that even in the ideal state, the high-sealed lamps have a certain probability of water leakage, and the leaky lamps are not in operation after being removed. It can also be dripped without leaking. Through experimental analysis, the researchers came to the conclusion that all outdoor high-power lamps have respiration during operation (except for explosion-proof lamps that are subject to high-pressure seals).
Due to the characteristics of thermal expansion and contraction of the gas, a certain pressure difference will be formed inside and outside the lamp before and after the lamp is turned on. During a certain period of time, the temperature and pressure in the lamp cavity will fluctuate within a small range, which is the normal exhalation process of the lamp. The probability of water leakage outside the lamp with poor air tightness is very high.
However, when the light does not stop, the luminaire will have an inhalation process. At this time, due to the negative pressure generated, the waterproof rubber strip of the lamp is deformed from the weak point under the action of air pressure, and forced inhalation will cause the lamp to inhale rainwater to varying degrees. Research by Kyrgyzstan? Waves of passengers shows that a working process of outdoor lighting is a breathing process, which is affected by various uncertain factors and forms a multi-nostril breathing. The leakage of the lamps is basically concentrated in the inhalation phase when the lights are not stopped.
Lamp and waterproof
According to the results of the experiment, the people of the Jiren wave companion research and development center conducted a study on the lamp urn. The lamp cymbal is based on aerodynamic principle, using five-stage channel diameter reduction (from 0.0254 square centimeter to 1.26 square centimeter), reducing the suction per unit area, the labyrinth wall-type resistance to moisture flow, and the lamp cap is squatting. Do not stagnate water, so as to achieve a small amount of slow pressure reduction, slow pressure to balance the pressure difference between the inside and outside of the lamp, the effect is very significant, in the heavy rain, the lights are also not dripping.
The lamp urn is made of ABS engineering plastic. It has beautiful appearance and is installed on the outer side wall of the lamp. It is suitable for various installation methods such as dive, overhead, and flat shooting. It can effectively prevent the lamp from leaking. It can also play a certain role for lamps with poor air tightness. Improve the role. The research results have been declared national patents.
