The Structure Of DC Lighting

The structure of the DC lighting lamp mainly includes the following parts:

PC lampshade: Made of high-transparency plastic, its main function is to protect the bulb and scatter the light, making the light softer and more uniform.

LED light source board: This is the core part of the LED bulb, consisting of a row of LED lamp beads, with the advantages of energy saving, high efficiency, long life and soft light.

Driver board: Responsible for connecting the LED light source board to the power supply, and controlling the brightness and working state of the bulb through the circuit to ensure a stable current supply.

Lamp cup: The internal heat needs to be dissipated through the lamp cup, and the normal working temperature of the LED bulb is ensured through heat conduction, heat convection and heat radiation.

Lamp holder: The LED bulb is connected to the power socket through the lamp holder and fixed in a suitable position.

The working principle of the DC lighting lamp is to provide a stable DC current to the LED through a constant current drive power supply. This method enables the LED light source to emit light evenly, improve the utilization rate of light and extend the service life of the lamp. DC power supply reduces high-frequency noise and flickering, protecting visual health.
