The LED uses a solid-state semiconductor chip as a light-emitting material. The principle of light-emitting is that when a forward voltage is applied to both ends, carriers in the semiconductor recombine, releasing excess energy to cause photon emission to generate visible light, far-infrared light, and near-infrared light. . The higher the operating temperature, the shorter the LED service life In fact, the actual life of an LED is often inversely proportional to the operating temperature. For example, the LED lifetime is 10,000 hours at 74 ° C, 25,000 hours at 63 ° C, and 50,000 hours at less than 50 ° C. The root cause is that the photoelectric conversion efficiency of the LED is extremely poor. About 15 to 20% of the electrical energy is converted into light output, and the rest is converted into thermal energy. Therefore, when a large number of high-power LEDs are used in one module and applied to high-brightness operation, these extremely poor conversion efficiencies will cause a major problem in heat dissipation processing. However, the application of the thermal imager can assist in the research and development of the LED module drive circuit (including the power supply), the light source semiconductor heat distribution analysis, and the light decay test. ‧ View LED module driver circuit dash cam front and rear,Wide angle dash cam,best dual lens dash cam,front and rear dash cam Hangzhou Hikauto Technology Co.,Ltd , https://www.hikmotorstore.com
LED is a new type of solid-state light source, and has shown excellent effects in special fields. Various types of LEDs, products using LEDs for secondary development, and products supporting LEDs are developing rapidly. New products are on the market and have been developed. Into a lot of new industries. Looking forward to the future, I also hope to improve even further.
In the development of LED products , engineers must carry out a part of the drive circuit design, such as rectifier circuit modules. With thermal imaging, engineers can quickly and easily find temperature anomalies on the circuit, making it easy to improve circuit design.
‧ Detection of LED light source semiconductor chip heating
Using the thermal imager, the engineer can obtain the infrared thermal image of the light source semiconductor chip, analyze the temperature of the chip during operation, and the temperature distribution. On this basis, the purpose of improving the life of the LED product can be achieved.
Thermal imaging cameras have been widely used in LED testing and quality control processes. The dual-lens Dash Cam means that the dash cam has 2 cameras.
The common dual-recording driving recorder has one camera to record the driver's front view,
and the other camera to record the external conditions behind the vehicle, including the outside road conditions. Vehicles, etc.,
can deal with situations such as rear-end collisions.
The front and rear two-way dash cam can record in all directions.
