Abstract
An illuminating device includes a first light module and a second light module. The first light module emits a first light beam to a first illuminating area, and the second light module emits a second light beam to a second illuminating area. The first light module includes a first blue chip emitting a blue light with a main wave peak from 461 nm to 480 nm.
Claims49
An illuminating device, comprising:
- a first light module emitting a first light beam to a first illuminating area, wherein the first light module comprises a first blue chip to emit a blue light;
- a second light module emitting a second light beam to a second illuminating area;
- and
- wherein the blue light emitted by the blue chip has a main wave peak in a range from 461 nm to 480 nm, and
- wherein the second illuminating area is different from the first illuminating area.
An illuminating device, comprising:
- a light module emitting a light beam,
- wherein the light module comprises:
- a blue chip to emit a blue light, and the blue light has a main wave peak in a range from 461 nm to 480 nm;
- and
- a fluorescent layer, disposed on the blue chip, comprising a red phosphor to transform a part of the blue light to a red light.
