1. Is the operating temperature of UV LED power supply the same as the ambient temperature?
Operating temperature and ambient temperature in electronic equipment parameters are not a concept.
Operating temperature: refers to the temperature of the equipment itself during normal operation (heating range);
Ambient temperature: refers to the required range of ambient temperature for normal operation of equipment.
2. How many degrees can the working temperature of UV LED lamp reach?
Temperature is related to heat dissipation. UV LED itself can work at very low temperature. Some high-power UV LEDs can often reach more than 100 degrees Celsius when working. However, high temperature has an impact on the life of UV LED, so the lower the temperature, the better. The high-power UV LED particles have a large calorific value. Shaoguan sterilization lamp beads also affect the service life of the LED, because the internal resistance is reduced and the current is too large due to heating. Easy to damage UV LED particles. Therefore, high-power UV LED lamps are equipped with radiators.
Generally, users who buy LED lamps usually consider the service life of lamps. What are the factors to maintain the long service life of LED lamps?
1. Power supply: LED lamp power supply is a very important component of LED lamp. Generally, there are two schemes of isolation and non isolation for the power supply. The isolation volume is too large and the calibration rate is low. It is used in low-cost products. Non isolated drive, small volume, led sterilization lamp beads, high calibration rate, low heat dissipation, high stability and high value-added products all use this power supply.
2. Light source: the light sources (LED beads or LED patches) used by LED lamps with the same brightness are different. Even for the same type of light source, the quality and price produced by different LED bead manufacturers are different. Major brands of LED products basically use good light sources.
3. Heat dissipation: the LED light source is attached to the aluminum substrate with good thermal conductivity. The heat dissipation of LED lamp beads and power supply are separated and do not interfere with each other, so as to ensure the rationality of heat dissipation. Generally, aluminum with high thermal conductivity and good heat dissipation is used. If the quality is poor, the heat dissipation with poor thermal conductivity is adopted, and even the heat dissipation of LED lamp beads is shared with the heat dissipation of power supply, resulting in poor heat dissipation and easy damage.
