Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a lighting device using a linear light source such as a straight tube fluorescent lamp.

[0002]

[Prior Art]

 In a conventional lighting device using a straight tube fluorescent lamp, the entire socket mounting surface of the socket mounting member for mounting the lamp socket is formed substantially perpendicular to the base plate. FIG. 5 shows an example of the mounting state of the illuminating device and its main configuration. In FIG. 5, 1 is a lighting device, 2 is a base plate of the lighting device 1, 3 is a socket mounting member of the lamp socket 4, and the socket mounting portion 3 a of the lamp socket 4 and the socket mounting surface S are the base plate 2. Is almost perpendicular to. 5 is a straight tube fluorescent lamp, 6 is a ceiling to which the lighting device 1 is attached, and θ is a diffusion angle of illumination light of the lighting device 1.

In the above configuration, when the fluorescent lamp 5 is turned on, the direct light and the reflected diffused light illuminate the area within the diffusion angle θ.

[0004]

[Problems to be solved by the device]

 However, since the conventional example is configured as described above, the illumination light is blocked by the socket mounting surface S of the socket mounting member 3, and the diffusion angle θ of the light in the left-right direction is narrowed. There was a problem that darkness could be formed in a wide area at the rear of the mounting member 3.

Further, in a lighting device with a shade, since the mounting surface of the shade is perpendicular to the base plate when the shade is mounted on the lighting device, it is difficult to position the shade. There was also the difficulty that the installation work facing the ceiling, including the replacement of fluorescent lamps, was extremely difficult.

The present invention has been made in order to solve the problems of the conventional example as described above, and the light of the linear light source is reflected obliquely downward by the inclined surface of the socket mounting member, so that the socket mounting is performed. It is an object of the present invention to provide a lighting device that can reduce the dark portion at the rear part of the member, has a wide lighting range in which it is extremely easy to attach and detach the shade to the lighting device main body and replace the fluorescent lamp, and has good maintenance workability.

[0007]

[Means for Solving the Problems]

 Therefore, the lighting device according to the present invention, in a lighting device using a linear light source, is a socket mounting surface of a socket mounting member which is disposed on a base plate so as to face each other and holds a lamp socket for mounting the linear light source. Is provided with a socket mounting portion that is substantially vertical to the base plate, and an inclined surface of a desired angle that expands toward the lower end from the upper end of the socket mounting surface excluding this socket mounting portion. The socket mounting member including the socket mounting portion and the socket mounting portion are integrally molded, and a trapezoidal side-shaped saddle whose both ends are inclined according to the inclined surface of the socket mounting member is provided. The above object is achieved by using as a guide for mounting the shade on the lighting device body.

[0008]

[Action]

 The lighting device according to the present invention configured as described above has an inclined surface on the socket mounting surface of the socket mounting member that expands from the upper end to the lower end of the socket mounting surface excluding the lamp socket mounting portion. Since the slanted surface is formed integrally, this slanted surface serves as a reflection plate to increase the light diffusion angle in the left-right direction of the lighting device, reduce the dark portion, and reduce the slanted surface when the shade is attached. It becomes an effective mounting guide, and the position of the shade mounting on the main body of the lighting device becomes extremely easy. In addition, the inclined surface makes it easier to see the terminal position of the lamp socket, so that the linear light source can be easily replaced.

【Example】

 An embodiment of this invention will be described with reference to the drawings. (Structure) FIG. 1 is a side sectional view of an essential part of an illuminating device showing an embodiment of the present invention, and FIGS. 2 to 4 are explanatory views of a closet structure showing a mounting state and an illuminating state of the illuminating device of the present invention. . Note that the same or corresponding portions as those of the conventional example are denoted by the same reference numerals.

In FIG. 1, 1A is a lighting device, 2A is a base plate that also serves as a reflector formed of an aluminum plate, and 3A is a socket plate 3b of a lamp socket (hereinafter referred to as a socket) 4 only as a base plate. 2A is formed so as to be substantially vertical, and the other socket mounting surface S around it is formed as an inclined surface 3b that expands toward the desired angle from the upper end a to the lower end b at a desired angle, for example, 30 °. This is a socket mounting member integrally formed by injection molding or the like with a synthetic resin that easily reflects light, and the socket mounting members 3A, 3A are arranged facing each other on both sides of the base plate 2A. Reference numeral 5 denotes a commercially available straight tube fluorescent lamp (hereinafter referred to as fluorescent lamp) which is an example of the linear light source L 1, and θ ₁ denotes a part of the irradiation light from the fluorescent lamp 5 which is the inclined surface 3b of the socket mounting member 3A. 3b is a diffusion angle of illumination light which is diffused and reflected in a direction intersecting with each other from 3b, and thereby the diffusion range is expanded. Further, 10 is a closet for storing articles, and 11 is a guard rail for guiding opening and closing of the door 12.

(Operation) An operation will be described based on the above configuration. First, when the fluorescent lamp 5 of the illuminating device 1A arranged in the closet 10 is turned on, the illuminating light of the fluorescent lamp 5 is the direct irradiation light and the diffusion angle of the illuminating light due to the reflected light from the base plate 2A. The diffuse reflection light from the inclined surface 3b of 3A expands to θ ₁ , and even when the lighting device is mounted on a relatively low ceiling like the lighting in the closet 10, it is clear in FIGS. 4 and 5. As described above, the range of darkness is reduced, and a wide range can be effectively illuminated, and thus it is possible to easily visually identify the items stored in a narrow storage part in every corner. Further, when the fluorescent lamp 5 is replaced, the terminal portion of the socket 4 can be easily seen due to the inclined surface 3b, which not only facilitates the replacement but also makes it very easy to attach and detach the shade 7 facing the ceiling. When mounting on the lighting device body, the inclined surface 3b of the socket mounting member 3A serves as a mounting guide for easy and accurate positioning, and the maintenance work of the fluorescent lamp 5 can be performed very easily.

[0012]

[Effect of the device]

 As described above, according to the present invention, the socket mounting surface of the socket mounting member for holding the lamp socket is integrally formed on the sloping diverging surface except the socket mounting portion, and when the shade is used, both sides of the shade are Since the end is formed in a trapezoidal side surface shape having an inclination that follows the inclined surface, and when the shade is attached, the seed is attached to the main body of the lighting device using the inclined surface as a guide, the diffusion angle of the illumination light is expanded. The darkness generated on the left and right of the lighting device is reduced, and it is possible to effectively illuminate every corner of a narrow storage unit. Also, the lamp socket mounting member is integrally formed of a resin material that easily reflects light, so the number of parts can be reduced, and due to the inclined surface of the socket mounting member, a linear light source such as a fluorescent lamp can be replaced. It is extremely easy and accurate to attach and detach the accompanying shade. This makes it possible to obtain an inexpensive lighting device having a wide lighting range, excellent maintenance workability, and a small number of parts.
