In particular, it relates to an arrangement structure of the small light source. 2. Description of the Related Art A conventional desk lamp uses, for example, a straight tube-shaped fluorescent lamp adapted to the shape of an appliance body.
The position of the fluorescent lamp is fixed. [0003] The prior art described above cannot extend the irradiation range in the longitudinal direction of the instrument main body, and is not convenient in that sense. SUMMARY OF THE INVENTION An object of the present invention is to provide a means for changing an irradiation range from a light source arrangement surface, and to enhance usability. [0004] In order to achieve the above object, there is provided a long tool main body, and a long auxiliary body extending in a longitudinal direction of the tool main body. A supporting means for supporting the same is provided, and a slide mechanism is provided between the appliance main body and the auxiliary main body to adjust the overall longitudinal dimension between them, and is disposed at substantially equal intervals along the longitudinal direction of the appliance main body and the auxiliary main body. A large number of small light sources, and when the longitudinal dimension is adjusted, the distance between each of the small light sources is changed substantially uniformly in proportion to the longitudinal dimension, so that the longitudinal size of the lamp body is freely set and irradiation is performed. It is an expanded range. [0005] The apparatus main body is provided with a long auxiliary body extending in the longitudinal direction of the apparatus main body, and the apparatus main body is provided with supporting means for supporting the main body. A slide mechanism for adjusting the overall longitudinal dimension between them is provided, and a large number of small light sources are provided at substantially equal intervals along the longitudinal direction of the appliance main body / auxiliary main body, and when the longitudinal dimension is adjusted. A desk lamp in which the distance between the small light sources changes substantially uniformly in proportion to it. DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described with reference to FIGS. The illustrated desk lamp according to the present invention,
An elongated auxiliary body 1 extending in the longitudinal direction of the instrument body 10
1 is provided. A support means for supporting the device body 10 is attached thereto. A slide mechanism is provided between the apparatus main body 10 and the auxiliary main body 11 to adjust the overall length in the longitudinal direction.
A large number of small light sources 20 are provided at substantially equal intervals along the longitudinal direction of the device main body 10 and the auxiliary main body 11. When the length in the longitudinal direction is adjusted, the distance between the small light sources 20 changes almost uniformly in proportion thereto. The support means for supporting the instrument body 10 is composed of a support 50 and a base 60. The auxiliary main body 11 slides from the inside of the instrument main body 10 and extends as appropriate. The illustrated small light source 20 is a high brightness light emitting diode. The small light sources 20 at both ends are fixed to the instrument body 10 and to the auxiliary body 11. The small light sources 20 arranged in the meantime are free. A spiral cord 40 for feeding power is arranged between them. Each of the small light sources 20 is approximately proportional to the length of the light source 20 when extended in the longitudinal direction.
Are drawn by the spiral cord 40 in the slide groove 30 and extend at substantially uniform intervals. As shown in FIG.
When the small light source 20 is pushed into the instrument body 10, each small light source 20 returns inside the slide groove 30 and contracts. Therefore, expansion and contraction can be appropriately performed, and the degree of freedom in the irradiation range increases. According to the present invention, the irradiation range can be flexibly changed by relatively sliding the instrument main body and the auxiliary main body in which the small light sources are arranged at equal intervals in the longitudinal direction. The packaging size can be reduced by downsizing the equipment when it is reduced. Since the irradiation range can be appropriately expanded, the usability increases. In addition, since the overall weight can be reduced by reducing the size of the light source, the supporting means (supports, etc.) can be simplified.
Further, if the light source is a high-brightness LED, the maintenance of the light source can be omitted.
