Abstract

A track lighting fixture includes a housing with sufficient space for a replaceable lamp and a voltage reduction transformer. Mounted on the base of the housing is a plate member which is removably engagable with the housing by the resilient interaction of spring clips with the housing.

Claims

1. A track lighting fixture comprising:

an elongated housing containing a space for a replaceable bulb and a voltage reduction transformer;

a substantially flat plate member engageable with the underside of said elongated housing, said substantially flat plate member containing means for mounting said replaceable bulb;

a plurality of resilient clip members located at one end of said plate member, said clip members being engageable with said elongated housing;

at least one resilient clip member located in the midst of said substantially flat plate member, said resilient clip member being engageable with said elongated housing;

whereby when said clip members engage said elongated housing, said substantially flat plate member lies flat against said elongated housing.

2. The track lighting fixture as defined in claim 1 further including surfaces located within said elongated housing, said surfaces constructed and arranged to engage said resilient clip members.

3. The track lighting fixture as defined in claim 2 wherein said resilient clip members are mounted on bosses.

4. The track lighting fixture as defined in claim 1 wherein said elongated housing includes a recess constructed and arranged to contain said substantially flat plate member when said substantially flat plate member is affixed to said elongated housing by said resilient clip members.

5. A method of relamping a track lighting fixture having an elongated housing and a substantially flat plate for mounting a replaceable lamp, said method comprising the steps of:

pulling said substantially flat plate member away from said elongated housing;

replacing said lamp;

engaging said resilient clip members located on one end of said substantially flat plate member with said elongated housing;

engaging a clip member located in the central portion of said substantially flat plate member with said elongated housing;

pressing said substantially flat plate member toward said elongated housing.

6. A replaceable lamp assembly for use with a track lighting fixture having an elongated housing comprising:

a substantially flat plate member;

means for mounting a replaceable lamp on said substantially flat plate member;

a plurality of resilient clip members located at one end of said substantially flat plate member;

at least one resilient clip member located in the midst of said substantially flat plate member;

said clip members being constructed and arranged to releasably mount said substantially flat plate member to said elongated housing.
