There are many types of LEDs, which vary in shape, color, brightness, power, and other aspects. On the one hand, they provide consumers with more choices, but on the other hand, they also increase the complexity of LED classification.
LED lights have prospered the lighting market, providing consumers with more choices, LED， Light emitting diode is a solid-state semiconductor device that can convert electrical energy into visible light. LED light sources have the advantages of using low-voltage power sources, low energy consumption, strong applicability, high stability, short response time, no pollution to the environment, and multi-color emission, although they are more expensive than existing lighting sources. This topic will introduce you to the advantages and disadvantages, types, selection, installation, cleaning and maintenance, and troubleshooting of LED lights. We hope it will be helpful for you to understand LED lights.
Advantages of LED lights
LED has very low power consumption. Generally speaking, the working voltage of LED is 2-3.6V, the working current is 0.02-0.03A, and it consumes no more than 0.1W of electricity. LED lights usually have a lifespan of over 50000 hours. LED lights do not contain harmful elements such as mercury and xenon, which are conducive to recycling and do not produce electromagnetic interference.
LED light price
The cheapest LED lighting fixture on the market, with a nominal power of 0.9 watts (equivalent to 25 watts of incandescent bulbs), costs 30 yuan, which is 6 times the price of incandescent bulbs of the same brightness and 2 times the price of ordinary energy-saving lamps. The price of LED desk lamps is often as high as eight or nine hundred yuan, and the price of imported brands is over a thousand yuan, which is 10 times the price of ordinary desk lamps.
The reasons for the price difference of LED lighting fixtures include brightness, anti-static ability, wavelength consistency, leakage current, emission angle, light attenuation size, LED chip origin/size, gel, etc.
LED light selection
The LED products produced by large factories have relatively fine workmanship in the lamp body, and the material of the LED driver housing is also relatively good. Generally, large factories use flame-retardant materials. Generally, large factories will obtain CE and ROSH certifications from the European Union, which can be provided by distributors. Warm white LED light shines on a white wall about 10-20 centimeters away. Good LED products have a soft halo, and the edges of the halo will have clear blue light. The cheaper the LED, the deeper and more obvious the blue light.
