Sheet-like light source device
View Patent ↗The present invention relates to a sheet-like light source device, including a light-conducting plate having at least one convex portion disposed on the lateral portion thereof; at least one light-source unit disposed on one side of the light-conducting plate, which includes a light source and a reflecting sheet; and a housing having a chassis and at least one frame; in which the frame is mounted on the edges of the chassis, and a concave portion corresponding to the convex portion of the light-conducting plate to hold the convex portion and a plurality of light-guiding mechanisms are formed on the frame. The present invention further has a housing for a sheet-like light source device, including a chassis and a frame mounted on the edges of the chassis, in which a concave portion and a plurality of light-guiding mechanisms are formed on the frame.
1. A sheet-like light source device, comprising:
a light-conducting plate having at least one convex portion disposed on one lateral portion thereof; and
at least one light-source unit disposed on one side of said light-conducting plate, comprising a light source and a reflecting sheet;
a housing for holding said light-source unit and said light-conducting plate, having a chassis and at least one frame;
wherein said frame is mounted on the edges of said chassis, and includes a concave portion corresponding to said convex portion of said light-conducting plate for holding said convex portion, and a plurality of light-guiding mechanisms are formed on said frame, and the light-guiding mechanisms are light-guide slots or light-guide holes.
2. The sheet-like light source device of claim 1 , wherein said light-guiding mechanisms are disposed in said concave portion of said frame of said housing.
3. The sheet-like light source device of claim 1 , wherein said slots are formed as a single slot, a branch slot, a curved slot or a saw-tooth slot.
4. The sheet-like light source device of claim 1 , wherein said frame is a black colored frame.
5. The sheet-like light source device of claim 1 , further comprising a plurality of optical films disposed on one side of said frame, other than on the line formed by said light-source unit and said light-conducting plate, so as to homogenize the light.
6. The sheet-like light source device of claim 5 , wherein said optical films are diffusing sheets, prism sheets or reflecting sheets.
7. The sheet-like light source device of claim 1 , wherein said housing is made of plastics or metal.
8. A housing for a sheet-like light source device, comprising:
a chassis; and
a frame mounted on the edges of said chassis;
wherein at least one concave portion and a plurality of light-guiding mechanisms are formed on said frame, and the light-guiding mechanisms are light-guide slots or light-guide holes.
9. The housing of claim 8 , wherein said light-guiding mechanisms are disposed in said concave portion.
10. The housing of claim 8 , wherein said slots are formed as a single slot, a branch slot, a curved slot or a saw-tooth slot.
11. The housing of claim 8 , wherein said frame is a black colored frame.
12. The housing of claim 8 , wherein said housing is made of plastics or metal.
