Kyocera's LED is mounted in a ceramic package and unlike plastic packages, ceramic shows little deterioration from heat and light. As a result, the LED lifetime is extended significantly. Shown below, the Kyocera LED lamp retains 95% of its initial luminous flux after 109,500 hours of continuous testing.
Correlated color temperature (CCT) also remains stable after the same time period.
Current Test of Kyocera LED Lamps
- 1. Current test conditions: ambient temperature of 25℃, LED chip surface temperature of 75℃,
voltage of 3.75W, current of 0.04A.
- 2. Current test of LED lamps does not assure lifetime of luminaires.
- 3. All test data herein was measured by Kyocera.
4. Lifetime of LED lamp is subject to change depending on ambient temperature,
LED junction temperature, voltage, current and operating environment.
Higher than 95% of initial luminous flux has been maintained after 109,500 hours.
Correlated color temperature (CCT) remains stable even after 109,500 hours.
