The energy-saving effect of the LED explosion-proof lamp is very good. This is everyone knows, so do you know what affects the life of the LED explosion-proof lamp? Today I will discuss this issue with you in detail.
Several factors affecting the life of LED explosion-proof lamps:
1. The primary factor is the impact of die quality on the life of the LED explosion-proof lamp:
In the manufacturing process of LED chips, other impurity ion pollution, lattice defects and other technological processes will affect their life, so the use of high-quality LED chips is the first condition.
2. Lamp design affects the reasonable design of LED lamps. In addition to meeting other indicators of lamps, a key issue is to dissipate the heat generated when the LED is lit. Using high-quality LED original products from companies such as Cree on different lamps, the life span of the LED can vary several times or even dozens of times. For example, the integrated light source lamps on the market (single 30 W, 50 W, 100 W), the light source of these products and the heat dissipation channel contact part of the heat is not smooth, as a result, some products cause light after 1-3 months of lighting. The decay rate is more than 50%. After some products use a low power tube of about 0.07 W, the light decays very quickly because there is no reasonable heat dissipation mechanism. These products have low technical content, low cost and short life span.
3. Lamp power supply is very important to the life of LED explosion-proof lamp:
Whether the power supply of the lamp is reasonable will also affect its life. Because LED is a current-driven device, if the power supply current fluctuates greatly, or the frequency of power spikes is high, it will affect the life of the LED light source. The life of the power supply itself mainly depends on whether the power supply design is reasonable. On the premise of reasonable power supply design, the life of the power supply depends on the life of the components.
4. The influence of ambient temperature on the life of LED explosion-proof lamp:
The current short life of LED lamps is mainly due to the short life of the power supply, and the short life of the power supply is due to the short life of the electrolytic capacitor. Another feature of the life index of electrolytic capacitors is that it must indicate the life under the working environment temperature of how many degrees, and it is usually specified as the life under the ambient temperature of 105 ℃. The lower the ambient temperature, the longer the service life of the capacitor. Even the most common electrolytic capacitor with a lifespan of 1,000 hours can reach 64,000 hours at an ambient temperature of 45°C, which is sufficient for ordinary LED lamps with a nominal 50,000 hours. Used it.
