Abstract
Abstract A hospital light has a fluorescent light mounting frame received within a base panel. The mounting frame and the base panel are held together by a slidable member which fits into a slot formed where the panel and frame come together. The frame is removable so that the lamps and other electrical components are easily changed. Also provided is a terminal block which allows for rapid rewiring of the lamps or other components.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
239 words
A hospital light comprising: a. base panel including upper and lower rail sections and a wall plate; b. a fluorescent light mounting frame receivable within the upper and lower rail sections of the base panel; c. a pair of members slidably held by the mounting frame and selectively extendable therefrom; d. means held relative to the base panel for receiving the slidable members when they are extended, whereby the mounting frame may be selectively held in the base panel; e. a first pair of tube holders fixed to the mounting frame; f. a second pair of tube holders fixed to the mounting frame; g. a third pair of tube holders fixed to the mounting frame; h. a terminal block fixed to the wall plate of base panel; i. electrical wiring connections between the terminal block and the first, second and third pairs of tube holders respectively; j. a light cover having edges complementary to edges of the base panel for enclosing the mounting frame; k. a first light partition disposed between the group of the first and second pairs of tube holders and the third pair of tube holders, said first light partition extending from the mounting frame toward the rear side of the light cover; and l. a second light partition extending from the rear side of the light cover toward the mounting frame and terminating adjacent but spaced from the light partition extending from the mounting frame.
Claim 2
Dependent Claim
239 words
A hospital light comprising: a. base panel including upper and lower rail sections and a wall plate; b. a fluorescent light mounting frame receivable within the upper and lower rail sections of the base panel; c. a pair of members slidably held by the mounting frame and selectively extendable therefrom; d. means held relative to the base panel for receiving the slidable members when they are extended, whereby the mounting frame may be selectively held in the base panel; e. a first pair of tube holders fixed to the mounting frame; f. a second pair of tube holders fixed to the mounting frame; g. a third pair of tube holders fixed to the mounting frame; h. a terminal block fixed to the wall plate of base panel; i. electrical wiring connections between the terminal block and the first, second and third pairs of tube holders respectively; j. a light cover having edges complementary to edges of the base panel for enclosing the mounting frame; k. a first light partition disposed between the group of the first and second pairs of tube holders and the third pair of tube holders, said first light partition extending from the mounting frame toward the rear side of the light cover; and l. a second light partition extending from the rear side of the light cover toward the mounting frame and terminating adjacent but spaced from the light partition extending from the mounting frame.
Claim 3
Dependent Claim
138 words
A hospital light comprising: a. a base panel including upper and lower rail sections and a wall plate; b. a fluorescent light mounting frame rEceivable within the upper and lower rail sections of the base panel; c. a pair of tube holders fixed to the mounting frame; d. a terminal block fixed to the wall plate of the base panel; e. a light cover having edges complementary to edges of the base panel for enclosing the mounting frame; f. electrical wiring connections between the pair of tube holders and the terminal block; g. a pair of members slidably held by the mounting frame and selectively extendable therefrom; and h. means held relative to the base panel for receiving the slidable members when they are so extended, whereby the mounting frame may be selectively held within the base panel.
