Abstract

A light device includes a housing having one or more chambers each formed between two flaps, one or more circuit boards received in the chambers of the housing, and a number of LED light members attached to the circuit boards to emit lights. The flaps of the housing may be used to concentrate or to reflect the lights emitted by the light members. The circuit board may be disengaged from the housing for being replaced with the other circuit board having new or good light members, when the old light members have been damaged or burned out.

Claims

1. A light device comprising:

a housing including at least one chamber formed therein and defined between two flaps,

at least one circuit board received in said at least one chamber of said housing, and

a plurality of LED light members attached to said at least one circuit board, to emit lights,

said flaps of said housing being provided to concentrate the lights emitted by said light members.

2. The light device as claimed in claim 1, wherein said housing includes at least one flange extended into said chamber thereof, to engage with and to retain said at least one circuit board in said at least one chamber of said housing.

3. The light device as claimed in claim 2, wherein said housing includes a channel formed by said at least one flange, to receive said at least one circuit board.

4. The light device as claimed in claim 1, wherein said housing includes a frame, and at least one casing secured to said frame and having said at least one chamber formed therein and having said flaps extended therefrom.

5. The light device as claimed in claim 4, wherein said frame includes a slot formed therein, said at least one casing includes a projection extended therefrom and engaged into said slot of said frame, to attach said at least one casing to said frame.

6. The light device as claimed in claim 4 further comprising at least one fastener engaged through said at least one circuit board, to secure said at least one circuit board to said at least one casing.

7. The light device as claimed in claim 1, wherein each of said light members includes a lens attached thereon.

8. The light device as claimed in claim 1, wherein each of said light members includes a flat outer surface formed thereon.

9. The light device as claimed in claim 1 further comprising at least one fastener engaged through said at least one circuit board, to secure said at least one circuit board to said housing.

10. The light device as claimed in claim 1 further comprising a receptacle including a base panel to support said housing.

11. The light device as claimed in claim 10, wherein said housing includes a cap attached thereon, and a plurality of LED light members attached to said cap to emit lights.

12. The light device as claimed in claim 10, wherein said housing includes a hood attached onto said base panel, to cover and shield said housing and said light members.
