Method and system for calculating remaining service life of LED lamps

Abstract

The invention belongs to the technical field of intelligent lighting equipment, and in particular relates to a method and system for calculating the remaining service life of an LED lamp. The method includes: step a: building the light intensity data model of the LED lamp under different powers through the server; step b: obtaining the light intensity data at the stable temperature when the LED lamp is turned on through the WIFI module of the LED lamp, and The data is sent to the server; step c: the server uses the light intensity data model to convert the light intensity data, and constructs a light attenuation model according to the converted light intensity data, and uses the light attenuation model to convert the light intensity data Calculate the remaining service life of the above-mentioned LED lamps. The invention can improve the calculation accuracy of the remaining service life of the LED lamp, thereby better protecting the human eye health of consumer families.

Description

technical field [0001] The invention relates to the technical field of intelligent lighting equipment, in particular to a method and system for calculating the remaining service life of an LED lamp. Background technique [0002] At present, traditional lamps are gradually being replaced by smart LED lamps. The lifespan of smart LED lamps is very long, and the service life of smart LED lamps given by LED light source manufacturers can reach more than 100,000 hours under appropriate voltage and current. In fact, the service life of smart LED lamps will depend on external environmental factors such as heat dissipation materials, aluminum substrates, drive power, power factor, product structure, etc., which also causes differences in the service life of smart LED lamps on the market. According to the inspection standards of LED lighting manufacturers, indoor lighting lumen maintenance rate L70 requires ≥25,000 hours, and outdoor and commercial lighting lumen maintenance rate L7...

Problems solved by technology

[0003] The above inspection standards are only the inspection standards of LED lighting manufacturers, but for consumers, the information they get when they buy products is only how many hours they can be used as stated in the purchase manual, and as time goes by, consumers It is impossible to accurately calculate the actual use time to judge whether the life of the lamp has expired; secondly, the experimental data test time is the continuous working time at a stable working temperature, and there are factors such as ambient humidity, electromagnetic interference, and static electricity when working or not working in actual use The aging degree of the product; again, the theoretical life of the LED is very long, even if the light decays to L50, it can still be lit continuously, but the light at this time can no longer meet the lighting requirements and is not suitable for continued use. human eye health
