Recently, Jingke Electronics' high-power gold-free ceramic package products 3535 (Easy Star) and low-power PLCC package products 3014 have been certified by the third-party authoritative certification body for more than 6,000 hours. "EnergyStar" LM-80 standard.
It is reported that Jingke Electronics' low-power PLCC package product 3014 has a luminous flux maintenance rate of 100.7% for 6000 hours under the test condition of 55 °C, and a luminous flux maintenance rate of 98.6% for 6000 hours under the test condition of 105 °C.
The high-power gold-free ceramic package product 3535 (Easy Star) is tested at an ambient temperature of 85 ° C. The 6000-hour luminous flux maintenance rate is 100.8%, the color coordinate drift Δu'v' is 0.001, and the test is performed at an ambient temperature of 105 ° C. The 6000-hour luminous flux maintenance rate was 100.7%, and the color coordinate shift Δu'v' was 0.0009. Both products have been tested to exhibit excellent luminous flux stability and chromatic stability, achieving virtually zero light decay.

The LM-80 test is a test method for the luminous flux maintenance rate of LED light sources. The test content includes the luminous flux maintenance rate of the light source at different temperatures, and the chromaticity maintenance rate of the light source at different temperatures. The test data of the LM-80 is used as reference data for the luminous flux of the finished light source to calculate the luminous flux maintenance rate and the chromaticity maintenance rate of the finished lamp.
