Abstract
An LED lighting device includes a case unit forming a light emitting space, wherein resting surfaces are formed at predetermined areas on the inner side of the case unit, substrates having LEDs mounted thereon and respectively rested on the plurality of resting surfaces, and heat-dissipating units formed in the outer side of the case unit for heat dissipation. Lifespan and user convenience can be improved.
Claims10
An LED lighting device comprising:
- a case unit forming a light emitting space, wherein a plurality of resting surfaces are formed at predetermined areas on the inner side of the edge of the case unit;
- a plurality of substrates respectively rested on the plurality of resting surfaces, wherein a plurality of LEDs that emit light in an inward direction of the case are mounted on each of the plurality of substrates;
- a plurality of heat-dissipating units formed in the outer side of the case unit for heat dissipation;
- and
- a reflection unit inserted in the case unit, and configured to reflect light emitted from the LEDs mounted on the plurality of substrates so that the reflected light is emitted through the light emitting space,
- wherein the reflection unit includes curved reflection parts for reflecting light emitted from the LEDs, respectively and a partition part positioned between the reflection parts for preventing light reflected respectively from the reflection parts from traveling to the opposite sides.
