Abstract
The present invention provides a light-emitting device capable of adjusting brightness. A plurality of light-emitting regions is disposed on a substrate. A power control module is connected electrically to the plurality of light-emitting regions and an input power source. The power control module converts the input power as a plurality of supply power sources, which turn on the plurality of light-emitting diodes in different regions and thus enabling them to emit light. Thereby, the light-emitting regions, and hence the brightness, can be adjusted according to the usage requirements.
Claims14
A light-emitting device capable of adjusting brightness, comprising:
- a substrate;
- a plurality of first light-emitting regions, disposed on said substrate;
- a plurality of second light-emitting regions, disposed on said substrate, and interlaced with said plurality of first light-emitting regions;
- and
- a power control module, connected electrically with said plurality of light-emitting regions and an input power source, converting said input power source as a first supply power source or a second supply power source, said first supply power source turning on said plurality of first light-emitting regions and enabling said plurality of first light-emitting regions to emit light, and said second supply power source driving said plurality of first light-emitting regions and said plurality of second light-emitting regions to emit light concurrently:
- wherein said plurality of first light-emitting regions and said plurality of second light-emitting regions are disposed on said substrate evenly.
A light-emitting device capable of adjusting brightness,
- comprising:
- a substrate;
- a plurality of light-emitting regions, disposed on said substrate, and arranged symmetrically;
- and
- a power control module, connected electrically with said plurality of light-emitting regions and an input power source, converting said input power source to a plurality of supply power sources, supplying power source to at least one pair of said plurality of supply power sources for said plurality of light-emitting regions and thus driving at least one pair of said corresponding light-emitting region to emit light symmetrically
- wherein said plurality of light-emitting regions are disposed on said substrate evenly.
