LED-based lamp with user-selectable color temperature |
| 摘要 |
A lamp including a first set of light emitting diodes configured to generate first light, a second set of light emitting diodes configured to generate second light, and a third set of light emitting diodes configured to generate third light. The first light, the second light, and the third light combine to produce white light. A first switch is located at a base portion of the lamp. The state of the first switch corresponds to a color temperature of the white light. A color temperature adjustment module is configured to vary outputs of the first, second, and third sets of light emitting diodes in accordance with the color temperature of the white light selected by a user using the first switch. |
