How to judge the merits of the LED high bay light source ?
As an industrial powerhouse in China, in the energy consumption of the factory, lighting energy consumption occupies a certain weight. Therefore, LED high bay light using new LED light source as light-emitting materials, which can achieve the effect of energy conservation and environmental protection, become the focus of people attention. So what factors influence the quality of LED high bay light source? how to judge the merits of the LED high bay light source ?
1. According to the semiconductor light-emitting diodes electric property from the LED high bay light source electrical to consideration
LED electrical characteristics of PN junction is a one-way nonlinear electrical conductivity, low voltage driver, and sensitive to static electricity, etc.The electrical characteristics is different with traditional light source, so the main measurement parameters include positive drive current, the forward voltage drop and reverse leakage current, reverse breakdown voltage and electrostatic sensitivity, etc.
2.According to the PN junction temperature of LED high bay light from the heat dissipation performance to consideration
The LED high bay light get higher power and luminous efficiency, solve PN junction temperature and heat dissipation problem is particularly important.Judge LED high bay light, general with thermal resistance, thermal performance parameters such as temperature, junction temperature said.
3. The life span and working reliability of LED high bay light
We evaluate the lifespan of LED high bay light does not mean that the cycle available from used to damage, and it is under the condition of rated power, luminous flux attenuation to the initial value of the specified percentage when the last time.The longer, the LED high bay light the longer lifespan.
4. In view of the LED light source of biological or body radiation safety into consideration
Due to the LED high bay light source is a narrow beam of light, high brightness light-emitting elements, the radiation may cause damage to the retina, so, the international electrotechnical commission IEC for application of LED light source used for different occasions. Specifies its effective radiation limit requirements and test methods, which is judge LED high bay light quality of an important factor. Among them, the European Union and the United States do mandatory to perform LED radiation safety testing .
Judgment of LED light source quality mainly is decided by these factors, in the future, LED lighting industry will become more competitive, which means opportunity and challenge coexist.
