LED panel lightLed panel lights are becoming the most popular led lights in the interior lighting design while the Led lighting technology is developing.
Components of the LED panel light:
1. LED Panel Light Body Frame
LED panel light body frame is used for covering the edge of the light. The frame provides the inner protection and thermal conductivity. Aluminium is the common material used for the frame. The advantages of the aluminium are the good heat dissipation and sleek outlook.
Nowadays, the PVC is the new material which is introduced into the market. Compared with aluminium, PVC made-up frame is more excellent on security and poorer on heat conductivity.
2. LED Panel Light Light Source.
LED 2835 is widely applied in LED panel light because of the advantages of high luminous output and lower cost.
Different quality of LED chipset and efficacy plays a big part in brightness, power consumption and lighting quality.
3. LED Panel Light Guide Plate
Light guide plate is the important component for LED panel light. Low quality LED panel lights will have non-uniformity of light and dark spots while it is operating. Understanding the types of plastic and refractive index is key to having a better LED panel light.
4. LED Panel Light Diffuser
LED panel light diffuser directly affects the light output. Panel light diffuser is made from PMMA or PC. PMMA-made diffuser is high on efficacy---92%. PC-made diffuser is excellent on oxidation resistance. PMMA is considerably used currently in the market.
5. Reflective Plate Reflector
It is applied to improve light efficacy to achieve the high brightness. It is made from translucent nanoscale material, its reflective rate could reach 92%.
6. LED Panel Light Power Supply
Nowadays, LED panel light with LED driver system is commonly acknowledged in the market. The drivers could regulate the voltage and current from the main power supply to light up the lights. The use of high quality driver directly affects the lifespan of the LED panel light.
7. Installation Accessories
Suspension wire, mounting bracket, screws,etc. are also used in LED panel light installation.
A great LED panel light should be equipped with all the good quality components, such like the body frame, LED chips, diffuser, reflector, drivers and also the accessories. Thereafter, it all goes into understanding the standard assembling and manufacturing process of the LED panel light.
