Is the view of LED lighting "not to worm" correct? It is said that "no insects" is one of the advantages of LED lighting. This advantage was questioned at the "Green Device 2009 Forum" LED Lighting Key Technology Symposium. Ruo Songshou (Principal Investigator of Research and Development of Fengming Factory of the company) in the street street lamp manufacturing company in the speech entitled "The ideal state of LED lighting, the discussion of past setting cases", the flying insects as the problem of LED lights one.
If the pine is said, it attracts flying insects with ultraviolet rays having a wavelength of 340 to 350 nm. Although the light spectrum of the above-mentioned wavelength is not detected in the light-emitting spectrum of the white LED equipped with the LED street light, according to the situation of the LED street lamp set by the company, "the higher the color temperature, the brighter the light emitted by the LED, and the easier the flying insects to the LED. Gathering." Therefore, if a seamless transparent cover is not covered around the light source so that the flying insects cannot enter the light source portion of the LED street light, the flying insects may intrude into the light source, causing electrical failure. There are even cases where a failure occurs within half a year. In the speech, Ruo Song showed a photo of the spider's netting near the LED light source. Now, the cause of attracting flying insects is still under investigation.
In the speech, the Japanese street lamp manufacturing company pointed out five problems of LED lights based on more than ten years of LED street lamp development experience. The flying insect problem is one of them. Other problems are the weight of the heat dissipating material; the connection method of the LED bulb and the power source; the understanding of the luminous efficiency and the light beam; the use of a weak current for lighting, so that the fluorescent switch cannot be used.
