Description

[Detailed description of the invention] Industrial applications The present invention relates to a lighting fixture that is attached to a ceiling surface.

Conventional configuration and its problems Conventional ceiling-mounted lighting fixtures are installed so that the upper edge of the bottom cover touches the main body chassis, which inevitably results in a large main body chassis, leading to a rise in material costs. In addition, depending on the mounting structure between the hanging fixture for hanging the main body chassis on the ceiling surface and the main body chassis, there is a risk that the lighting equipment may fall.Object of the InventionThe present invention aims to solve the above-mentioned problems. The purpose is to provide a lighting fixture that is low in price and is less likely to fall.

Structure of the Invention In order to achieve the above-mentioned object, the present invention is configured such that the upper edge of the lower cover attached to the lower surface of the main body chassis is in contact with the ceiling surface, and the hook piece of the hanging fixture attached to the ceiling surface is A hole for passing through and a locking hole formed near the hole into which the hook piece is inserted are formed on the top surface of the main body chassis, and the abutting action between the lower cover and the ceiling surface is used to prevent the main chassis from falling. This is to reduce the amount of material used in the chassis.

Description of examples Next, embodiments of the present invention will be described with reference to the drawings.

1 is a channel-shaped metal main body chassis with a ballast 2, a switch 3, a glow socket 4 a glow lamp 5 on the bottom.
A long sub-chassis 6 is attached at right angles to the main body chassis 1 at both ends of the lower surface, and a fluorescent lamp socket 7 is attached to the sub-chassis 6. Although this sub-chassis 6 is designed for four lights, it can be easily changed to a length for two or three lights as needed.

A hole 8 is provided in the upper surface of the main body chassis 1, and notches 9 are provided at two opposing locations around the hole 8.

Reference numeral 1o denotes locking holes, which are provided at four locations around the hole 8.

11 is a hanging fixture attached to the ceiling surface 12, and 1 at both ends
The letter-shaped hook piece 13 is passed through the hole 8 and inserted into the locking hole 10, so that the main body chassis 1 is suspended. When passing the hook piece 13 through the hole 8 , it is preferable to pass it through the notch 9 and then rotate the main body chassis 1 and insert the hook piece 13 into the locking hole 10 . The presence of four locking holes 10 is useful when it is desired to change the orientation of the main body chassis 1 at right angles. Note that, regardless of these examples, in order for the hook piece 13 to be hung, it is sufficient that the main body chassis 1 has at least two holes, that is, a hole corresponding to the hole 8 and a hole corresponding to the locking hole 10. . 16
is a bottom cover that has a side frame 16 and a bottom plate 17, and is attached to the bottom surface of the main body chassis 1 by screwing thumbscrews 18 into the sub-chassis 6, and the upper edge of the side frame 16 is attached to the ceiling surface 12.
be in contact with

A square hole 19 is formed in the lower plate 17, and the fluorescent lamp socket 7 projects downward through the square hole 19. 2o is a fluorescent lamp. Or 21 is a hole through which the glow lamp 5 is exposed.

Although the fluorescent lamp 20 is located below the lower cover 16, the lower cover 16 may be in the form of a normal type glove that covers the fluorescent lamp 20.

Effects of the Invention The lighting fixture of the present invention has the following effects due to the above-described configuration.

(1) The chassis requires less material, resulting in lower costs.

(Oan) When the upper edge of the bottom cover comes into contact with the ceiling surface, the main body chassis, which is in a fixed relationship with the bottom cover, is pulled down, and the hook pieces and the locking holes are not unlatched, and the lighting Tools do not fall.
