Hello everyone, I am Xiaobian Qinmeng today, let ’s introduce the issue of how to judge good or bad LED lamp LED lamps. Here are Qinmeng's summary of this issue and related issues. Let’ s take a look. Article Catalog Navigation: 1, LED lights are not on for a period of time, what's going on? 2. LED lights have good or bad judgment method 3. What is the matter of LED lights and lightness 4. How much is LED lights one meter 5, LED electronics What's the matter when the lights are brokenLED lights are not on for a while Fault 1. Light failure Light is a relatively professional term, which is very troublesome to explain. We can simply understand it as the luminous capacity of the luminous body is attenuated, that is, after a period of time, the emitting body aging, so it is better to light up before. LED lights have no explicit regulations. Good lamps, only 3%of the light decay of 10,000 hours, and almost a little lamps, one thousand -hour light decay is limited to 3%, thanks to gratitude, to put it bluntly, although the theoretical life of LED lights is longer than incandescent lamps and fluorescent lights, But it also depends on the quality of LED lights. The poor quality products that are cheap will not have a high life. Of course, if you use a set of lamps, you spend ten years and twenty years. I am afraid that no matter how good the quality is, it will produce light decay. And the higher the temperature of the environment, the longer the continuous opening time, and the higher the voltage in the line, the faster the LED light decay. Light is strictly aging and does not belong to faults. But most users feel that the lights of their homes are not as bright as before, because they are declining because of light.Fault 2. Burning We take off the panel of the lamp, and we can see the lamp beadboard inside ▼ LED lamp, which is composed of these small lamp beads. Many small lamp beads are connected in series, and each string of small lamp beads are parallel (if the lamp is small, each lamp bead may be parallel). When the lamp was burned at a certain moment, the string of lamps that are located will not be lit, but the other skewers are still bright -when the panel is blocked in front, we can’t see it clearly, but the lamps feel that the lamps are not as bright as before. It's right. LED lamp is determined by the good or bad judgment methodYou can first pay attention to the color of each LED lamp bead through the naked eye. If there is a small black dot on the lamp bead, it is burned out. Secondly, you can also use a multimeter to measure the multimeter gear to the diode (the gear of the beep) before the measurement, and then use the multimeter to contact the metal on the left and right sides of each lamp one by one. The sound of bee sounds, it means that the lamp bead is bad. LED light is dim and light. LED light is darker and darker, which is a very common phenomenon. The reason why the LED light is darkened is nothing more than the following three points.LED lamp bead requires working in DC low voltage (below 20V), but our usual municipal electricity is AC high voltage (AC 220V). To turn the electricity needed to be a lamp bead, it needs a device called LED constant current driver power. Theoretically, as long as the parameters of the driver match with the lamp board, it can be continuously powered and used normally. The internal driver is relatively complicated. Any device (such as capacitors, rectifies, etc.) fails, which may cause changes in the output voltage, and then cause the lamp to dark. Drive is the most common failure in LED lamps. Usually, it can be resolved after the driver is replaced.LED burns LED itself is combined by one by one. If one or part of it is not bright, it will inevitably make the entire lamp darker. The lamp beads are generally connected in series and then connected in parallel -so a certain lamp bead is burned, which may cause a group of lamp beads to not light up. The surface of the beads after the burned beads has obvious black spots. Find it, use a wire to connect to its back, short -circuit or replace a new lamp bead, which can solve the problem. LED occasionally burned one, it may happen. If it is frequently burned, another manifestation of the driver's problem -the driver's failure is to burn the beads.LED light The so -called light decay is that the brightness of the luminous body is getting lower and lower -this situation is more obvious in incandescent lamps and fluorescent lamps. LED light cannot avoid light decay, but its light failure is slow, and it is difficult to see changes with the naked eye. However, it does not rule out inferior LEDs, or inferior light beadboard boards, or due to objective factors such as poor heat dissipation, which leads to faster light attenuation in LED. LED light is one meter LED light is an energy -saving lamp, the brightness can be adjusted, the use is convenient, and the price depends on the Watshi, ranging from 8 yuan to 25 yuan. LED electronic lamp is broken. LED light is damaged 1. The voltage of the current is unstable. Many 2. may also be a short circuit for LED due to damage to their own quality. Its original voltage drop is passed on to other LEDs. Pipeline's power supply channel local short circuit, which causes this situation to be a component in the line, or the short circuit of other wires may also be water in the lamp, because water is water, because water is water, because water is water, because water is water, because water It is conducted, so that the lines of the lamp will be short -circuited. The above is the answer to how to judge the good or bad questions and related questions about the LED lamp LED lamp LED lights of Hongzhu brand. I hope it will be useful [responsible editor: Qinmeng] |
