Abstract

A light casing includes a top part and two side parts which are snapped to two ends of the top part. Each of the two side parts has a groove defined in an outer periphery thereof so that two rails are engaged with the two grooves. A mediate member is connected between the two side parts and two end plates are respectively connected to the two ends of the top part and the two side parts. Lamps are connected between the two end plates and located in the mediate member. Two light casings are able to be connected with each other by using a connection block engaged with two respective grooves of the two light casing.

Claims

1. A light casing comprising:

a top part;

two side parts each having a top member and a bottom member, a connection section connected between said top member and said bottom member, a groove defined between said top member and said bottom member, said two top members respectively engaged with two ends of said top part;

a mediate member connected between two respective bottom members of said two side parts, and

two end plates respectively connected to said two ends of said top part and said two side parts.

2. The light casing as claimed in claim 1, wherein said top part has two sidewalls and each of said sidewalls has a first connection port and a second connection port, each of said two side parts having a first engaging port for connecting with said first connection port and a second engaging port for connecting with said second connection port.

3. The light casing as claimed in claim 1, wherein each of said bottom members has a flange extending from an edge thereof and a connection port is connected to said flange, said mediate member being a U-shaped member and two sides of said mediate member connected to said two connection port.

4. The light casing as claimed in claim 3 further comprising a face plate engaged between said two flanges of said two bottom members of said two side parts.

5. The light casing as claimed in claim 1 further comprising two rails engaged with said two grooves and each of said rails is held by a rod which is adapted to be connected to a ceiling.

6. The light casing as claimed in claim 1 wherein each of said top member and said bottom member has a screw receptacle for connecting said end plates.

7. The light casing as claimed in claim 1 further comprising a connection block which is engaged with two respective grooves of two light casings.

8. The light casing as claimed in claim 1 further comprising an extending light casing which has one end engaged with said groove.

9. The light casing as claimed in claim 8 wherein said extending light casing includes two loop-shaped retainers and two ends of a side plate are retained in said two retainers.

10. The light casing as claimed in claim 9 wherein said of said retainers has an engaging end which is slidably engaged with said groove of said side part.
