The successful shooting of magazine covers is inseparable from excellent photographers and various sophisticated equipment. LED panel lights are one of them. So, do you know what it is made of?
Panel light aluminum frame: It is the main channel for LED heat dissipation, with a simple appearance and good texture.
LED light source: Usually 5630 is used for LED lamp beads, and 3528 and 3014 are also used. The latter has low cost and slightly poor light efficiency.
LED light guide plate: It uses optical grade acrylic/PC sheet, and then uses high-tech materials with extremely high reflectivity and non-light absorption, and uses UV screen printing technology to print light guide dots on the bottom surface of the optical grade acrylic sheet. The optical grade acrylic sheet is used to absorb the light emitted from the lamp and stays on the surface of the optical grade acrylic sheet. When the light hits each light guide point, the reflected light will spread to all angles, and then destroy the reflection condition and shoot out from the front of the light guide plate.
LED diffuser plate: The diffuser plate mainly plays a role in shielding debris and light diffusion in the use of LED panel lights, so that the light from the light guide plate is more uniform. The main materials of the diffuser plate are: PC, PMMA, PS, PP, nowadays The most used is the PS material.
Reflective paper: It reflects the remaining light on the back of the light guide plate to improve light efficiency.
Rear cover: The main function is to seal the LED panel light, usually 1060 aluminum, which can also play a role in heat dissipation.
Drive power supply: Use constant current power supply, this mode has high efficiency, PF value is as high as 0.95, use constant voltage with constant current power supply, stable performance.
