Street lamp bulb

الوصف

LED is undoubtedly the first choice of lighting products in the world, but due to the inherent characteristics of LED, the requirements for working temperature are more stringent, and the heat dissipation of LED lamps has been bothering industry. Although we all know that led bulbs are light weight, high standardization and easy to handle, it is also clear that not all lighting products can use LED bulbs, such as street lamps, industrial and mining lamps, floodlights and other high-power LED lighting products, which are difficult to use the low power LED bulbs on the market.
（1） The shell source integrated LED technology has some defects
Since the beginning of history, the light source and the lamp shell have been separated. Edison invented the bulb, which does not include the shell. The shell of the lamp plays the role of protecting the light distribution and beautifying. Whether it is incandescent lamp, low iodine tungsten lamp, sodium pressure lamp, high pressure sodium lamp or electrodeless lamp, the light source is independent of the shell. In the era of LED, the situation has changed fundamentally, and the integration of light source has become a trend. The reason is that the working temperature of LED is very low, generally below *5 degrees. If the lamp shell is not involved in the heat dissipation, the working heat of LED can not be well evacuated, resulting in heat accumulation and improving the working temperature of light source, which directly affects the service life of LED light source.
(2) "Shell source separation" creates high-power LED bulbs
First of all, the cost of consumers is small. Consumers will no longer have to buy aluminum in order to buy light bulbs. To buy light source is to buy light source, and the cost will be greatly reduced. Secondly, we should not discard the original good lamp shell because of energy-saving LED lamps, so as to better protect the lighting culture engraved with urban history. Moreover, the interdependence between lamp posts will not be broken, and the appearance and color of urban lamp posts will not be sacrificed for energy saving. In addition, the safety factor has been improved. Originally, it was necessary to put a *0 kilogram lamp cap on the old lamp post, but after using the LED bulb, the weight of the lamp cap will not increase but decrease. Finally, LED bulb will be the terminator of environmental protection risks of high power LED lamps on the market.
