Color temperature adjustment for LED lamps using switches |
摘要 |
A light-emitting diode (LED) lamp includes a number of different color LEDs that can be turned on and off in different combinations using an external switch operable by a user. A user or a controller can adjust the color temperature of light output by the lamp. The color temperature change may be a user preference and can compensate for decreased phosphor efficiency over time. |
