Most manufacturers now advertise that the life of the LED lamp is 50,000 hours. The life of the entire lamp is generally 35,000 hours, and some even directly mark the service life of 100,000 hours. In terms of current technology, such a lifetime only exists in an ideal environment, and it does not consider the premise of light attenuation. In practical applications, LED lights are affected by many factors, which can not reach the theoretical value. With the continuous progress of LED technology, the continuous decline of costs, and the continuous improvement of energy-saving and energy-saving performance, LED lamps are gradually entering our lives. Most families have replaced the original incandescent lamps and energy-saving lamps. What determines the service life of the LED lights we buy? Let’s analyze it in detail below:
A single LED lamp and a lamp composed of LED lamps pass the test, and there is still a certain difference in aging. This difference can not be analyzed from the environment of LED lights and various other parameters.
The chip of the LED lamp is one of the important factors that determine the service life of the LED lamp. The material and specifications of the LED chips produced by some small factories are not relevant. Even if the packaging process is good in the later period, there may be dead beads and serious light decay Series of questions.
The different packaging processes of LED lamps will have a considerable impact on the quality of the product. The LED lamp encapsulated with ordinary primer has a 76% reduction in light attenuation under the same aging environment as the LED lamp encapsulated with A-type low-decay glue. Therefore, choosing an LED lamp made with a good packaging process will greatly extend its service life.
3.Voltage and current
LED lights use direct current. We often compare the power supply of LED lights to its heart. The drive is not only responsible for lighting the lights, but also determines the service life of LED lights. A stable power supply voltage and a suitable working current can Extend the life of the LED lamp, assuming that there is an instantaneous high voltage, and even the LED lamp will break down. In theory, the current is smaller and it is more durable. This depends on the actual use environment and requirements.
4. Heat dissipation
When the LED lamp beads are working, the individual lamp beads will be heated less, and the temperature of the bracket will not exceed 45℃. At this time, the life of the LED lamp will be ideal, but when the LED lamp forms a lamp group, the corresponding temperature will rise. High, it is not conducive to long-term use of LED lamps. For the problem of heat dissipation, one is to choose a good aluminum substrate to help better heat dissipation. Some high-power outdoor lights will design heat sinks. The design and material of heat sinks are crucial factors. Good heat dissipation The chip can dissipate heat faster.Another way is to increase the distance between the lamp beads, preferably the distance between the lamp beads is more than 25mm.
Generally, it is strictly forbidden to cover objects during the working process. One is because the LED lamps are not good for heat dissipation, and the other is that they are prone to fire.
In short, LED lights are afraid of heat, the higher the temperature, the shorter the LED life, the lower the temperature, the longer the LED life. The ideal working temperature of LED is of course at minus 5 ℃.But this is basically impossible. Therefore, consumers must understand the performance of LED lamps when choosing them.When it is used, it should be reasonably protected so that it can exert its optimal use effect and let it add luster to you.
