With the accumulation of use time and the erosion of sun and rain, outdoor LED linear lights will feel that LED linear lights are not as bright as before after a certain number of years. There is a technical term in the lighting industry - light decay.
With the accumulation of use time and the erosion of sun and rain, outdoor LED linear lights will feel that LED linear lights are not as bright as before after a certain number of years. There is a technical term in the lighting industry - light decay. The physical phenomenon of light decay is an unavoidable problem for LED lamps, just like life, old age and death, lamps also have a service life.
In the use of outdoor environments, daily sun and rain are inevitable factors that cause the brightness of LED line lights to decline, in addition to this unavoidable condition factors There are also human factors. The service life of the general LED is about 50,000 hours, with the average person's thinking to understand, a total of 50,000 hours of life, if the light is turned on at 6 o'clock every evening until 12 o'clock in the morning, only 6 hours a day, 365 days a year, only 2190 hours a year, it is not possible to use 23 years.
But this is only theoretical data in the laboratory, in actual use, the service life of LED linear lights can not be calculated by mathematical multiplication and division, and incorrect use will also accelerate the light decay time. There is also in the process of wall washer manufacturer installation, installers often want to save installation time and installation convenience, in the lamp power supply is not installed according to the number of LED line lights known by the manufacturer, often overloaded series lamp number, resulting in LED line lamp voltage and current instability and other serious damage to the life of LED line lamp behavior. According to market feedback information, the general outdoor LED linear light service life will be 2-3 years, some can reach five or six years, but the longer the time, the lower the brightness of the LED linear light.
