In the process of using LED lights, a lot of people are met dead the phenomenon of light, why in the use of LED street lamp light phenomenon will appear in the process of death, what is the appropriate solutions? Why there are dead lamp LED lights? The main reason for the LED street lamp store, there are two: LED the leakage flow is big, cause the p-n junction failure, lead to the LED street light is not bright. LED street light along with the rapid growth of the national economy, the contradiction between supply and demand of energy in our country, start there is a serious shortage of electricity supply situation, saving energy that is an urgent need to solve the problem. Therefore, the development of new type of high efficiency, energy saving, long life, high color rendering index, environmental protection of the LED street lamp for city lighting energy saving is of great significance. LED street lamp manufacturers of LED street lamp with conventional street lamps, the LED light source adopts low voltage dc power supply, by GaN power type synthetic efficiency white light, blue light leds and yellow is efficient, safe, energy-saving, environmental protection, long service life, fast response speed, high color rendering index of unique advantages, can be widely used in road. Housing available, resistance to high temperature of 135 degrees, low temperature resistant da 45 degrees. This kind of situation usually will not affect the operation of other LED lights. LED lights inside connection wire broken, no current through the LED and LED to a death ray. This kind of situation will affect the normal operation of the other LED lights. How to solve the problem of LED street light beam? In the LED packaging production line, grounding resistance of various equipment whether meet the requirements, it is also very important. General requirement for grounding resistance of 4 ohms, part of the high demand of grounding resistance should be 2 ohm or less. Welding temperature can also lead to the LED light phenomenon to death. Leds in the lead the expansion coefficient under high temperature is 160 ℃ several times. Internal gold solder joints is due to excessive thermal expansion, cold and be pulled, lead to blind Angle phenomenon of lamps and lanterns. Above is about LED street light beam phenomenon and the related solutions. If you have any questions, welcome to call the advisory. We will update for you more related instructions.
