Abstract
An illuminating device comprises a base, a light source and at least one first layer, wherein said light source is assembled on said base to emit a first color temperature light, while first layer is located on the base along the first light irradiation path. The first light is passed through the first layer to react with said first layer to form a second color temperature light for emission, wherein said first color temperature is ranged from 2800K to 20000K, while excitation wavelength range of said first layer is mainly beyond the wavelength of ultraviolet lights for further adjusting the second color temperature range.
Claims24
An illuminating device comprising:
- a base;
- a light source assembled on said base to emit a first light with a first color temperature ranging from 2800K to 20000K;
- and
- a first layer located above said base and said light source along a first light irradiation path, said first layer receiving the first light having the first color temperature, wherein a second light with a second color temperature that is different from the first color temperature and ranges from 2800K to 7000K is produced when said first light passes through said first layer to react with said first layer, thereby producing the second light with the second color temperature,
- wherein the light source comprises a plurality of discrete illuminating components, each covered by a separate second layer, and wherein the light emitted by each illuminating component passes through the corresponding second layer to form the first light.
An illuminating device comprising:
- a base;
- a light source supported on said base, emitting a first light with a first color temperature ranging from 2800K to 20000K;
- a light guiding component supported by the base, extending over said light source along a light irradiation path, wherein a space is defined between said light guiding component and said light source;
- a first layer supported on a surface of the light guiding component, said light guiding component and said first layer receiving the first light having the first color temperature, wherein a second light with a second color temperature that is different from the first color temperature of the first light and ranges from 2800K to 7000K is produced when said first light passes through said first layer to react with said first layer, thereby producing the second light with the second color temperature.
