Composition and light guide plate of LED panel light
In recent years, the sales of LED panel lights have been on the rise, and more and more manufacturers have entered the LED panel light market. In the office lighting market, you can see all kinds of LED panel lights.
Here, I would like to share with you the basic knowledge of some panel lights and their basic structure.
The main components of LED panel lights include:
①Frame: mainly for heat dissipation, generally aluminum profiles
②Diffusion plate: Block the sundries to make the light more uniform ③Light guide plate: Change the trajectory of the light to make it evenly arranged
④ Reflective film: make the light of the light guide plate emitted from the front
⑤ Bottom plate: Auxiliary heat dissipation, block the intrusion of foreign objects
⑥PCBA: LED light board, the light source of the panel light
⑦Power supply: drive the panel light to light up
Here, we need to focus on the light guide plate of the panel light. The following is an introduction to the process and thickness of the light guide plate:
1. Process: silk screen, laser dotting, V groove thickness: there are many common thicknesses - 3mm, 4mm, 6mm, 8mm, the thickness is different, the type is different, the plate is different, the price is also very different, the light guide plate is mainly light guide As long as the light guide efficiency is high, the uniform illumination is high, and the phenomenon of yellowing and blistering will not occur after lighting for a long time.
With the current technology, the light guide efficiency of the silk-screened light guide plate is high and the effect is good, but the price is also expensive! - The price difference ranges from 5-15 yuan.
2. Thickness: The thicker the thickness of the plate, the higher the illuminance. Now there are more 4mm light guide plates on the market, because the price difference between 4mm and 6mm plates is about 20-30 yuan. Therefore, you must know the type of panel light guide plate you need, the raw material manufacturer and thickness of the panel, the light guide plate is relatively high in moisture in this piece, and the price of the poor light guide plate is about 30 yuan!
When purchasing panel lights, you may wish to distinguish whether their grades and prices are consistent from these perspectives. Don’t just pursue low prices, but also need to shop around to find products that are more suitable for you.
