led street light Fixtures Light decay characteristics: How to extend the service life

Time:  2023-07-11    Author:        Look:  151

led street light fixture is one of the most widely used street lights at present, it has many advantages such as energy saving, environmental protection and long life. However, with the growth of use time, the brightness of LED lights will gradually decrease, which is the phenomenon of light decay. This article will introduce the light decay characteristics of led street light fixtures and how to extend their service life.

What is the light decay characteristic of led street light fixture?

The light decay feature of led street light fixtures refers to the phenomenon that the brightness of LED lights gradually decreases with the increase of use time. This is because during the use of LED lights, the luminous efficiency of the LED chip will gradually decrease, resulting in a decrease in the brightness of the entire led street light fixture.

What are the causes of light decay in led street light fixture?

1. LED chip aging: The service life of LED chip is limited, and long-term use will lead to aging of LED chip and decrease of luminous efficiency.

2. Heat problem: The LED lamp will heat up during the working process, if the heat dissipation is not good, the life of the LED chip will be shortened.

3. Environmental factors: such as temperature, humidity and other factors will also affect the life of led street light fixture.

How to extend the life of led street light fixtures?

1. Optimize the heat dissipation system of led street light fixture: ensure good heat dissipation, effectively reduce the working temperature of LED chips, and extend the service life.

2. Use high-quality LED chips: Ensure the quality of LED chips and extend the service life.

3. Properly adjust the driving current: properly reduce the driving current of the LED lamp, which can effectively extend the service life of the LED lamp.

4. Control the working temperature of LED lights: Control the working temperature of LED lights, which can extend the service life of LED lights.

5. Reasonable design of optical structure of led street light fixture: Reasonable optical design can improve the light efficiency of LED light, reduce the heat of LED light, and extend the service life of LED street light fixture.

How to evaluate the light decay of led street light fixture?

Evaluating the light decay of led street light fixtures is mainly carried out through the life cycle assessment of LED lights and the actual brightness test. The life cycle assessment can simulate the service life of the LED lamp through simulation experiments, and the actual brightness test can evaluate the light decay of the LED lamp by measuring the brightness of the LED lamp.

conclusion

led street light fixture light decay problem is the current application of led street light fixture process need to pay attention to the problem. In order to extend the service life of led street light fixture, we need to optimize the heat dissipation system, use high-quality LED chips, properly adjust the drive current, control the working temperature of LED lights, and rationally design the optical structure of led street light fixture. At the same time, when evaluating the light decay problem of led street light fixture, it is necessary to carry out the life cycle assessment of LED lights and the actual brightness test to accurately evaluate the light decay of led street light fixture.
