Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a louvered lighting fixture in which a louver is disposed below a lamp, particularly a straight tube fluorescent lamp, and which is subjected to glare-cutting treatment.

Glare cut processing is done in consideration of the fact that the human eye is particularly susceptible to glare within a 30° range (glare zone) relative to the line of sight, and the brightness that falls within this glare zone is low. It refers to something that is made to become.

In contrast to lamps in which this treatment is performed using a reflector, in lamps in which a louver is attached below the lamp to also perform glare cutting treatment in the longitudinal direction of the straight tube type lamp 3, conventionally a reflector and a louver are used. Since the entire circumference of the lamp is covered with a louver, it is necessary to remove and install the louver and the frame that holds the louver when replacing the lamp.

The method of installing the louver depends on the method, for example, screwing, hooking, hinge, etc., but attaching and removing the louver is very time consuming and can be a maintenance problem in places where a large number of lighting fixtures are installed. It becomes.

The present invention has been made in view of these points, and its purpose is to provide a lighting fixture with a louver that allows the lamp to be replaced even when the louver is attached and detached, and that does not affect glare cutting processing. It is in.

The present invention will be described in detail below based on illustrated embodiments.

Figures 1 and 2 show one embodiment of the present invention. First, this ceiling-embedded type will be explained. In the figures, 1 is the main body, 2 is the socket, 3 is the lamp, and 4 is the reflector. , 5 is a louver, the main body 1 has a V-shaped cross section, sockets 2 are fixed to both sides, and one end of each of reflectors 4, 4 is connected to the upper surface.

The other end of the reflector 4 is supported by a ceiling base component 9 that receives the edge of the ceiling material 8, and the line connecting the lamp 3 and this edge is approximately 30 degrees or more with respect to the horizontal plane. ing.

This is a glare-cutting process that prevents light from directly entering the glare zone.

The louver 5 is composed of a plurality of parallel louver pieces 6, and the center of each louver piece 6 is fixed to the lower end of the main body 1, so that the louver 5 is disposed below the lamp 3.
Each of the louver pieces 6 extending in a direction perpendicular to the longitudinal direction of the lamp 3 performs a glare cutting process in the longitudinal direction of the lamp 3.

Here, the intervals between the respective louver pieces 6 are such that a hand can fit there, or a lamp replacement tool can fit there.

Further, there is a gap slightly larger than the diameter of the lamp 3 between the edge of each louver piece 6 and the reflecting plate 4.

Therefore, when replacing the lamp 3, insert your hand or a tool between the louver pieces 6, remove the lamp 3 from the socket 2, take it out from between the louver 5 and the reflector 4, and replace the new lamp 3 in the opposite direction. Follow these steps to attach it to socket 2.

There is no need to remove the louver 5, and even if the lamp 3 is dropped when replacing the lamp 3, the louver 5 will stop it from falling, so the louver 5 also serves as a stop for the lamp 3 to fall. It will be fulfilled.

The embodiment shown in FIG. 3 is of the type in which the lower end of the reflector 4 protrudes below the ceiling surface although it is an embedded type, and shows an embodiment in which the reflector 4 is integrally fixed to the main body 1. ing.

The one shown in FIG. 4 is of a type that is directly attached to the ceiling surface, and an outer frame 10 is integrally connected to the lower edge of the reflecting plate 4.

In both the embodiments shown in FIGS. 3 and 4, the lamp 3 can be replaced using exactly the same procedure as in the embodiments shown in FIGS. 1 and 2.

Needless to say, the glare-cutting treatment has also been sufficiently applied.

The embodiment shown in FIG. 5 is a semi-indirect lighting type that uses a ceiling material 8 as a reflector 4, and a louver piece 6 is attached at the center of the lower end of the main body 1 that is directly attached to the ceiling material 8. At the same time, a louver frame 7 made of an opaque material is attached to the edges of the plurality of louver pieces 6 to form the louver 5, and the upper end of the louver frame 7, which is at approximately the same height as the lamp 3, and a reflector plate are attached. A space slightly larger than the diameter of the lamp 3 is left between the lamp 3 and the ceiling material 8, which will function as the louver frame 7.
The line connecting them is at an angle of about 30° or more with respect to the horizontal plane.

Glare is cut by the louver frame 7 located on the side of the lamp 3.

As described above, in the present invention, a reflective plate and a louver frame are placed on the sides of the lamp to perform glare cutting, and a louver piece is provided below the lamp for glare cutting in the longitudinal direction of the straight tube type lamp. Despite the fact that the louver is placed in place, the louver cannot be attached or removed because the lamp can be replaced by passing the lamp through between the reflector and the louver, and by inserting your hand or a lamp replacement tool between the louver pieces. This makes it easy to replace the lamp.
