Measurement of the integral Led street lights China


 
Islam,Free Web Resources,Humor
Led street lights China http://www.jhetech-Led.com/product/Led-street-Lights-Manufacturers-China.html is a modular lighting Light source for road lighting device, in addition to one or more light-emitting diodes as a Light source, also include other components, such as optical, mechanical, electrical and electronic components. The LED is sealed and not disassembled parts in lamps and lanterns, in the case of not confuse, we call it LED street light.

Under the rated power frequency , when Led street lights China is in stability, power supply voltage should be stable in the rating range of plus or minus 0.5%,( such as if rating is a range, chose one between them); During the measurement, the supply voltage should be stable in the plus or minus 0.2%, within the scope of the fundamental wave frequency deviation shall not be greater than 0.1%, and harmonic distortion is less than 3%; For the life test supply voltage should be stable within plus or minus 2%. Since the ballast LED street lamp power supply directly by the power supply; when external control lamp test, generally under the baseline controller driver or equivalent driving conditions, electricity is offered by the power supply. LED street lamp control can also be under the condition of equivalent driven directly by the dedicated device power supply. The special device of the output voltage or current or power should be stable in the range of + / - 0.2%. If ac drives, should make corresponding regulation. Frequency and waveform distortion under normal circumstances, the fundamental wave frequency deviation shall not be greater than 0.1%, the harmonic distortion is less than 3%.

LED lamp under test after 100 h of aging and then to the provisions of this technical specification in all kinds of tests or measurements. Though the LED is not affected by gravity, but the heat dissipation will have obvious effect of LED street lights work, After 100 h of burning, the lamp go though all kinds of tests or measurements in the provisions of this technical specification. Though the LED is not affected by gravity, the heat dissipation will have obvious effect of street lights work. The shining features of LED street lamp also restricted by working attitude. Therefore, during the test or measurement, if no special requirement, light should be with the provisions of this technical specification standard measuring attitude put in free space. When measure LED street light, it should remain stationary state. Its photoelectric parameters may have a strong dependence of heat, so when testing or measuring, it should work in thermal equilibrium state. Monitoring ambient temperature at the same time, monitor itself working temperature to ensure that the test repeatability. LED junction voltage of the p-n junction can directly reflect the working temperature. Therefore, if it is possible to monitor voltage, the monitoring should be preferred junction voltage. Otherwise, you should monitor the temperature of the LED street lamp shell parts specified.
