摘要:
A vehicle headlamp system (100) includes a lamp device (12; 22) and a control device (14) to control the brightness thereof while in operation. The lamp device includes at least a first light emitting diode unit (126; 226; 326) providing a first color temperature, and at least a second light emitting diode unit (128; 228; 328) providing a second color temperature different from the first color temperature. The control device is coupled to the lamp device for changing the brightness ratio of the second LED unit to the first LED unit and controlling the resulting color temperature of the lamp device.

摘要:
An LED illuminating apparatus includes a lampshade (11), a cover (12) engaged with the lampshade, a heat dissipation module (13) received in a hollow tube cooperatively formed by the engaged lampshade and cover, a light source (14) engaged on the heat dissipation module, and two connectors secured at opposite ends of the lampshade and the cover. The lampshade defines a plurality of vents therein (111, 112). The light source faces the cover and light emitted from the light source radiates out of the LED illuminating apparatus through the cover.
