"LED Lamp Series", this series of articles will explain the composition and characteristics of LED Lamps , explain them thoroughly, clearly and thoroughly, including DALI, BLE, Zigbee, mobile phone control and other types of intelligent lighting. I hope it can help everyone, increase their knowledge, and answer questions and questions. At present, I don’t know how many chapters there will be in this series, and wherever I write it. If you think the article is pretty good, please follow, collect, like, forward, and leave a message to communicate. --------------Sinan (a little person who has been engaged in the LED industry for more than 20 years)
In front of it, we introduced LED light tubes, LED bulb light .
Have you found that a complete LED lamp composition is nothing more than LED lamp beads, driving power supply, aluminum substrate , lamp housing, and optical devices.
LED lamp beads are light sources, light emitting devices, which convert electrical energy into light energy and return the heat of the department.
driver power supply converts mains power 220V into a safe and suitable voltage and current for LED light source operation.
Aluminum substrate serves as the carrier of LED lamp beads, fixes the lamp beads, absorbs and diffuses the LED heat into the air.
The lamp housing mainly has three functions. The first is to diffuse the LED heat into the air, the second is to protect the internal components of the lamp, and the third is to form a unique appearance shape and a convenient installation structure. Of course, there are also a large number of lamps in the market that do not include driver power supplies.
Optical device passes the light emitted by the LED light source through secondary processing, filters or changes the angle of the light, and forms a certain angle or surface lighting, so that the light is more uniform and softer. Another function is to protect LED light sources.

lamp tube , bulbs, panel lights, industrial and mining lamps, three-proof lights , street lights, courtyard lights , line lights, etc. are all these structures. Although their appearance sizes and shapes vary greatly, their structural composition is the same without exception. Since their structural composition is the same, their evaluation parameters are similar. Below, we try to list the parameters that measure their performance.
We can find appropriate parameters from optical, electrical, and physical structures.
Optical part: display index, strobe index, UGR, color temperature CCT, luminous flux/lumen, illuminance/brightness, luminous angle, light effect, etc., are all common required parameters for us. When purchasing LED lamps, you need to know these parameters in detail.
electrical parts: voltage, current, power, conversion efficiency, voltage withstand level, insulation type, voltage and current adjustment rate, ripple , power factor , harmonic , overvoltage protection, overload protection, short circuit protection, surge current, leakage current, electromagnetic interference and other parameters.
Physical structure: size, temperature and humidity, material, etc.
