What are the reasons for the failure of LED tri-proof lights?
Because the luminous power of LED high-power tri-proof lamp is higher than that of household lamps, LED tri-proof lamp manufacturers have made great efforts in the design of heat dissipation substrate fins and heat dissipation modules. After assembling LED high-power tri-proof lamp, it is necessary to dissipate heat from the lamp The outside of the module is protected by baking paint to prevent weather erosion. Otherwise, the spray paint of the external protection will seal the heat of the cooling module back, resulting in poor heat dissipation and the failure of the high-power LED light.
LED tri-proof lamp manufacturers analyze the reasons for light decay:
1. The LED high-power tri-proof lamp is used outdoors, and there are environmental interference factors, so most manufacturers protect the radiator shell of the LED high-power tri-proof lamp with anodizing treatment, or spray paint to avoid acid and alkali. Corrosion of substances, the life of anode treatment is not long, and it will still oxidize and discolor after a long time. If it is necessary to dismantle heavy work, it will not only be time-consuming and labor-intensive, but also increase maintenance costs. However, the general baking paint has no heat dissipation function, and the paint body will form a barrier by itself, which is equivalent to increasing the thermal impedance of the LED high-power tri-proof lamp radiator. Not only does it not help, but because the heat energy is enclosed in the metal halide lamp radiator, Let the LED luminous power drop, and finally lead to serious light failure.
2. The luminous heat energy of LED high-power tri-proof lights belongs to small-scale concentrated heat energy. When using high-power street lights, the power input power is also large, and the temperature of the LED interface is quite high. When the street lights continue to work for a long time, the heat dissipation module If the effective heat dissipation cannot be achieved, the service life and luminous performance of the LED will be affected, and the serious light failure of the LED high-power tri-proof lamp is caused by these factors.
Energy-saving LED tri-proof lights are commonly used in places where lighting is required in the living room, living room, kitchen, bathroom, balcony, table lamp, etc. So how to choose high-quality lights? From the point of view of power supply alone, the life of LED power supply is about 20,000 hours, depending on the heat dissipation and weather conditions! The length of working hours? There are many factors to choose!
The solder joints on the high-quality energy-saving LED tri-proof light strips should be lubricated, and the amount of solder is suitable for uniformity. General product operation manuals and specifications, energy-saving LED tri-proof light fixtures should also be equipped with a light strip connector or a card holder.
The requirements of the power supply are high power, high power products, low heat generation and high stability. Usually there are two types of blocking and non-blocking schemes in the power supply part. The size of blocking is too large and the power is low. In application, many problems will occur in the installation. It is not as good as the market prospect of non-blocking products. Here we want to discuss non-blocking products. drive plan. Although traditional SMD products can connect the positive and negative electrodes through the gold wire of the chip, the heat generated by the chip is also connected to the silver pin through the gold wire. The conduction of heat and electricity is conducted by money, and the accumulation of heat takes a long time. It will directly affect the life of the energy-saving LED tri-proof lamp.
