Shandong about LED street lamp lighting factory co. , LTD. , analysis the reason of dead lamp: we often encounter the LED is not bright, also said the death of light phenomenon in the industry.

shandong street lamp lighting factory co. , LTD. It analyses the reasons of the light-emitting diode die lamp; We often encounter led not bright, this is also the personage inside course of study says death ray. Has been blamed on two things: one is the high light emitting diode leakage, is the one inducing the inefficiency of p-n junction, lead to led street light is not bright, generally does not affect other led lights work; Secondly, internal connections cut off of the led street light led to no current through the leds and death lamp. This kind of situation will affect the normal operation of the other led lights. The reason was that the leds lamps low working voltage ( The working voltage of red, yellow, orange light-emitting diodes (leds) to 1. 8 v - 2. 2 v, blue, green, white light diode work voltage of 2. 8 - 3. 2V) , series and parallel is usually needed to adapt to different working voltage. The more series of led lights, the greater the impact. As long as one of the led street lamp open circuit, the entire series of led street lamp will not light up. Led lamp is the key to product quality and reliability. How to reduce and eliminate dead Angle, improve product quality and reliability, is the key to the packaging and application of enterprise needs to solve problems. Shandong street lamp lighting factory co. , LTD. Is an enterprise specializing in the production of all kinds of lamps, such as solar street light, led street light, high lamp, lithium battery solar street lamp, garden lamp, landscape lamp, etc. , high quality and low price. Welcome new and old customers to come to consult. In a word, the reason of dead lamp has a lot of, can't list. From packaging, application to use every link will likely die modulation phenomenon. How to improve the quality of the light emitting diode products is packaging enterprises and enterprises should attach great importance to and seriously study the problem. From the chip and the stent to leds encapsulation went the whole process should be in accordance with the quality system to operate. Only in this way, can improve the quality of the light emitting diode products comprehensively, so as to realize long life and high reliability. In circuit design, the choice of varistor and PPTC components to improve the protection circuit, increase the number of parallel circuit with constant current switching power supply and increase the temperature protection are effective measures to enhance the reliability of led products. Went as long as the packaging and application of enterprises in strict accordance with the quality system running, the quality of the LED products will reach a new level.
