What are the reasons for the failure of the factory's three-proof light
Because the luminous power of the factory tri-proof lamp is greater than that of household lamps, the tri-proof lamp factory has added fins on the heat dissipation substrate. The design of the heat dissipation module has been painstakingly. Anti-climate corrosion, otherwise the external protection paint will seal the heat of the heat dissipation module back, resulting in poor heat dissipation and the failure of the three-proof light.
Reasons for light decay:
1. The tri-proof lamp is used outdoors, and there are disturbing factors of the weather, so most manufacturers protect the radiator shell of the factory's tri-proof lamp with positive treatment, or spray paint to avoid the corrosion of acid and alkali substances. The lifespan of Yangji treatment is not long, and it will oxidize and discolor after a long time. If it needs to be dismantled for heavy work, it will not only be time-consuming and labor-intensive, but also increase the maintenance cost. Generally, baking paint has no heat dissipation function, and the paint body will form an insulating effect by itself, which is equivalent to increasing the thermal impedance of the three-proof lamp radiator. Not only does it not help, but because the heat energy is enclosed in the metal halide lamp radiator, the luminous power decreases. Then lead to serious light failure.
2. The luminous heat energy of the three-proof lamp is attributed to the small-scale concentrated heat energy. When the high-power street lamp is used, the power input power is also large, and the temperature of the LED interface is quite high. Under the long-term continuous operation of the street lamp, the heat dissipation module cannot Effective heat dissipation, which then affects the service life and luminous performance of the LED, the serious light failure of the three-proof lamp is formed by these factors.
