The mounted ballast 9 is a ceiling on which the lighting device 1 is mounted, and h is the height of the lighting device 1.

In the above configuration, when the fluorescent lamp 5 is turned on, the operation of the ballast 8 suppresses an increase in the current flowing through the fluorescent lamp 5 to maintain stable illumination.

[0004]

Since the prior art is constructed as described above, the ballast 8 formed by a choke coil or the like is interposed between the base plate 2 and the fluorescent lamp 5, and the ballast 8 Since the heat itself generates heat, it is necessary to enlarge the heat radiation space in order to suppress the temperature rise within a range where the heat does not affect the members of the ceiling 9 or to make the base plate 2 a box-shaped heat shielding structure. As a result, the height h of the lighting device 1 increases,
When used as lighting in a small section such as a storage closet, it is higher than the height of the guide rail that opens and closes the door of the closet, so that the lighting device can not be mounted on the door opening and closing part suitable for the mounting position There were difficulties.

[0005] Further, since the conventional fluorescent lamp lighting device itself incorporating a human body sensor has not yet been put into practical use, when automatic lighting is required, a place and a labor for separately providing the human body sensor are required. There was a problem of needing.

The present invention has been made to solve the above-mentioned problems of the prior art, and includes a human body sensor, a ballast, and the like at the rear of a socket mounting portion of a socket mounting member for holding and fixing a lamp socket. An object of the present invention is to provide a storage device for a transformer, thereby providing a lighting device which is reduced in height and is significantly thinner.

[0007]

Therefore, a lighting device according to the present invention is provided on a base plate facing each other, holding and fixing a lamp socket for mounting a linear light source, and further comprising the linear light source. At the rear of the socket mounting portion of the socket mounting member that detachably holds the shade that covers, a storage portion for storing one of the transformers including the human body sensor and the stabilizer is provided, and an exhaust slit provided on the rear end surface of the storage portion A socket mounting member formed integrally with a human body detection lens mounting hole provided on the bottom surface of the storage unit of the human body detection sensor and a suction slit hole provided on the bottom surface of the storage unit for storing the transformer; and the socket. A slit for ventilation is formed between the side end surface of the shade held by the mounting member and the socket mounting member, and the socket mounting member is By making both the human body sensing sensor housing side and the transformer housing side the same shape, one of the holes provided on the bottom of the housing portion is a lens mounting hole and the other is a slit member mounting hole for intake, It is intended to achieve the above object.

[0008]

In the lighting device according to the present invention having the above-described structure, a human body sensor and a housing for a transformer including a ballast are provided integrally with a socket mounting member, and a slit for promoting heat radiation is provided in the socket. Since the socket mounting members formed on the lower surface and the rear end surface of the mounting member and disposed opposite to each other are formed in the same shape,
Dissipation of heat from heating elements such as transformers becomes effective,
The height of the lighting device is reduced, allowing closets and other doors to be attached to the guide rails, and the temperature rise on the ceiling side of the lighting device is kept low, thereby avoiding thermal effects on ceiling members. Can be

In addition, since the human body sensor is incorporated in the lighting device, when the linear light source needs to be turned on, the linear light source is automatically turned on accurately, and the mounting place of the human body sensor and the time and effort for mounting are reduced.

Further, since the socket mounting member for housing the human body sensor and the transformer is formed by the same mold,
The number of parts is reduced.
