Composition Of LED Lighting Fixtures
Regardless of the type of lighting fixture, it is composed of the following components:
1. Power input interface: Used to connect power sources, such as the bulb head of a bulb lamp.
2. Shell: It is generally composed of aluminum profiles with good heat dissipation. The characteristics of the appearance of the lamp, the heat dissipation effect of the LED, and the heat dissipation design of the shell directly affect the efficiency and service life of the lamp.
3. Lampshade: Not only does it cover the lamp to gather light together, but it also prevents electric shock and protects the eyes. Therefore, every lamp has lampshades such as PC lampshade, glass lampshade, and plastic lampshade
4. LED light source: composed of N LEDs combined together, it is the core component of this luminaire, and the luminaire emits initial visible light through it
5. Driver power supply: Due to the low operating voltage and narrow operating voltage range of a single LED, direct power supply is necessary. LEDs cannot function properly and are easily damaged. Therefore, constant voltage and current control must be applied to the input power supply through a circuit. The quality of the driver power supply directly affects the service life of the LED and the entire lighting fixture
