Problems solved by technology

However, since the life of the LED lamp is fixed, a fixed voltage and current will be applied to the LED lamp during the use of the existing LED lamp. Therefore, after the LED lamp is used for a corresponding period of time, it will gradually become darker until it does not meet the brightness requirements. , resulting in a limited service life

Embodiment 1

[0029] This embodiment proposes a method for prolonging the service life of LED lamps, setting the threshold value of the light intensity attenuation rate, collecting the light intensity of the LED lamp at different times, and regularly increasing the The input current of the LED lamp is used to increase the light intensity of the LED lamp by increasing the current when the LED light intensity is weakened, so as to meet the light intensity demand.

[0030] Among them, according to the threshold value of the light intensity decay rate and the light intensity at different times, the method of regularly increasing the input current of the LED lamp is: when the light intensity decay rate of the LED lamp is less than or equal to the threshold value of the light intensity decay rate, increase the input current of the LED lamp, Wherein, light intensity attenuation rate=second light intensity / first light intensity.

[0031] Specifically, such as figure 1 As shown, the method for exte...

Embodiment 2

[0049] This embodiment proposes a method for prolonging the service life of LED lamps, setting the threshold value of the light intensity attenuation rate, collecting the light intensity of the LED lamp at different times, and regularly increasing the The input current of the LED lamp is used to increase the light intensity of the LED lamp by increasing the current when the LED light intensity is weakened, so as to meet the light intensity demand.

[0050] Among them, according to the light intensity attenuation rate threshold and the light intensity at different times, the method of regularly increasing the input current of the LED lamp is: determine the light intensity attenuation coefficient of the current environment according to the first light intensity and the second light intensity, and determine the light intensity attenuation coefficient according to the first light intensity and the light intensity attenuation rate threshold to obtain the third light intensity, deter...

Abstract

The invention discloses an LED lamp and a method and system for prolonging its service life. The invention collects the light intensity of the LED lamp at different times, and according to the light intensity attenuation rate threshold value and the light intensity of the LED lamp at different times, in the LED When the light intensity of the lamp decreases, the light intensity of the LED light is increased by increasing the input current of the LED light, so that the light intensity of the LED light meets the light intensity requirement, thereby prolonging the service life of the LED light.

Description

technical field [0001] The invention relates to the technical field of LED lamp applications, in particular to an LED lamp and a method and system for prolonging its service life. Background technique [0002] LED lamp is a kind of high-efficiency and energy-saving light source, therefore, it is widely used in real life. However, since the life of the LED lamp is fixed, a fixed voltage and current will be applied to the LED lamp during the use of the existing LED lamp. Therefore, after the LED lamp is used for a corresponding period of time, it will gradually become darker until it does not meet the brightness requirements. , resulting in a limited service life. Contents of the invention [0003] The invention provides a method for prolonging the service life of the LED lamp, which can greatly increase the service life of the LED lamp. [0004] In order to solve the above-mentioned technical problems, the present invention adopts the following technical solutions to achi...
