Aging test method and device for LED luminaire production

Abstract

Disclosed are an aging test method and a device for LED luminaire production. The method includes selecting a highest temperature test point; selecting a lowest temperature test point; arranging temperature sensors at the test points; powering on an LED lamp; testing and recording temperatures at the highest and lowest temperature test points respectively; calculating a measured temperature difference value when recording a highest stable temperature value and a lowest stable temperature value; and comparing the measured temperature difference value with a standard temperature difference value, determining the product to be qualified if the measured temperature difference value is in the range of the standard temperature difference value, and determining the product not to be qualified if the measured temperature difference value is out of the range of the standard temperature difference value. According to the aging test method and device, a scientific method and technology are adopted, zone tests at fixed points and fixed time are performed according to material characteristics of the LED heat dissipation technology, and simultaneously, quality of LED luminaire products is guaranteed and aging cost of the LED luminaire products is greatly reduced.

Description

technical field [0001] The invention relates to a production aging test method of an LED lamp and an aging test device thereof. Background technique [0002] In order to ensure the quality of the LED lighting products produced by LED lighting manufacturers, after the production and assembly are completed, they will generally conduct a 48-72 hour aging lighting test on all products. During the test period, the products that are continuously lit are judged as qualified products, and these products are packaged and put into storage after the aging is completed. This detection method has the following problems. First, it needs to spend a lot of aging electricity for 48-72 hours of aging lighting test. Taking an average of 10,000 LED lights per day as an example, assuming that each LED light is 20W, the aging time In 48 hours, the electricity price is calculated at RMB 1 per kilowatt-hour, and the electricity consumption for aging alone is RMB 9,600 per day. If calculated for 72...

Problems solved by technology

This detection method has the following problems. First, it needs to spend a lot of aging electricity for 48-72 hours of aging lighting test. Taking an average of 10,000 LED lights per day as an example, assuming that each LED light is 20W, the aging time In 48 hours, the electricity price is calculated at RMB 1 per kilowatt-hour, and the electricity consumption for aging alone is RMB 9,600 per day. If calculated for 72 hours, the electricity consumption for aging is RMB 14,400 per day; Large test factory and quite a lot of test equipment, still take the products of the above factory as an example, if it is tested for 48 hours, there are 20,000 LED lights in the test process, if it is tested for 72 hours, there are 20,000 LED lights in the test process There are 30,000 LED lamps on the way to test, which requires a large test factory and a lot of related equipment; the third is this test method, the test result is only to obtain the confirmation of 48-72 hours of lighting, and cannot be scientific Therefore, the repair rate of products shipped out after testing in this way is still high, which increases the maintenance cost of the factory
