Abstract
Disclosed herein are a backlight unit and a lighting system including the same. The backlight unit includes a first reflector and a bottom cover, a plurality of reflector support parts disposed on the bottom cover, each of the reflector support parts including at least two first and second slanted surfaces adjacent to each other about at least one inflection point, a second reflector disposed on the plural reflector support parts, and a light source module disposed between the first reflector and each of the second reflector.
Claims18
A lighting system, comprising:
- a first reflector and a bottom cover;
- a plurality of reflector support parts disposed between the first reflector and the bottom cover, each of the reflector support parts having a first slanted surface that is adjacent to a second slanted surface about at least one boundary, the first and second slanted surfaces having curved shapes, wherein each of the reflector support parts includes support legs;
- a second reflector disposed on the plurality of reflector support parts and extending along the first and second slanted surfaces of the plurality of reflector support parts, the second reflector having a curved shape that corresponds to the curved shapes of the plurality of reflector support parts;
- and
- a light source module disposed between the first reflector and the second reflector, the light source module including a light emitting diode;
- a cover plate coupled to opposite side portions of the bottom cover, the light source module and the first reflector being disposed at the cover plate;
- and an optical member facing the reflector support parts and supported by the cover plate;
- and at least one reflector support part has a support pin formed on an upper portion to support the optical member,
- wherein the support legs include
- a first support leg disposed at a rear side of the first slanted surface, the rear side of the first slanted surface being in a rearward direction with respect to a front of the first slanted surface facing the second reflector, and
- a second support leg disposed at a rear side of the second slanted surface, the rear side of the second slanted surface being in a rearward direction with respect to a front of the second slanted surface facing the second reflector.

A display device, comprising:
- a display panel;
- a first reflector and a bottom cover;
- a plurality of reflector support parts disposed between the first reflector and the bottom cover, each of the reflector support parts having at least a first slanted surface and a second slanted surface adjacent to each other about at least one boundary, the first and second slanted surfaces having curved shapes, wherein each of the reflector support parts includes support legs;
- a second reflector disposed on the plurality of reflector support parts and extending along the first and second slanted surfaces of the plurality of reflector support parts, the second reflector having a curved shape that corresponds to the curved shapes of the plurality of reflector support parts;
- and
- a light source module disposed between the first reflector and the second reflector, the light source module including a light emitting diode emitting a light for the display panel;
- a cover plate coupled to opposite side portions of the bottom cover, the light source module and the first reflector being disposed at the cover plate;
- and
- an optical member facing the reflector support parts and supported by the cover plate, and at least one reflector support part has a support pin formed on an upper portion to support the optical member,
- wherein the support legs include
- a first support leg disposed at a rear side of the first slanted surface, the rear side of the first slanted surface being in a rearward direction with respect to a front of the first slanted surface facing the second reflector, and
- a second support leg disposed at a rear side of the second slanted surface, the rear side of the second slanted surface being in a rearward direction with respect to a front of the second slanted surface facing the second reflector.
