Problems solved by technology
[0003] However, in this light irradiation device, it is necessary to separately prepare the partition plate and install it in the casing, so there is a problem that the weight of the whole device and the manufacturing cost increase.
In addition, in such a light irradiation device, it is necessary to arrange the electric wires for supplying electric power to the light source in the casing, but arrange them in such a way that the flow of the air sent into the gaps between the cooling fins is not obstructed. It is very troublesome. In addition, in order to ensure the wiring space, the arrangement of the radiator and the fan in the casing will be restricted, and there will be a problem of increasing the size of the device itself.

Embodiment Construction
[0040] Hereinafter, the light irradiation device of the present invention will be described with reference to the drawings.
[0041] like figure 1 and figure 2 As shown, the light irradiation device 100 of the present embodiment includes three light source units PU of the same structure, three fans FN (exhaust devices), and a housing CA for accommodating them. Figure 3 ~ Figure 5 As shown, the light source unit PU is equipped with the light source 10 which consists of several LED11, the radiator 40 to which the light source 10 was attached, and the electric wire 60 electrically connected to LED11.
[0042] The light source 10 is provided on a metal substrate 20 having a rectangular shape and excellent thermal conductivity. On the surface of the substrate 20, at the center in the width direction (Y direction), from one end side to the other end side in the longitudinal direction (X direction), a light source mounting region 21a (in the image 3 , indicated by a dot-dash li...

The problem addressed by the present invention is, while saving wasted wiring space to be more compact, to increase the cooling efficiency of a light source by controlling the flow of gas flowing in a gap between each heat dissipation fin without increasing weight or manufacturing cost. A light illumination device (100) is provided with: a heat dissipation body (40) having substrates (20), (30) for which an electric wire attachment area and a light source attachment area are set at different surface positions, as well as a plurality of heat dissipation fins (41) erected on the back surface of the substrates (20), (30); a light source (10) provided on the light source attachment area; and an electric wire (60) electrically connected to the light source (10), with one end provided on the electric wire attachment area. The plurality of heat dissipation fins (41) are formed with space open between each other, such that gas flows in the spaces, with one end side of the electric wire wired from the front surface side of the substrate to the heat dissipation fin side, and running along the heat dissipation fin from the base side to the tip side of the heat dissipation fin within the range of the external shape of the heat dissipation body.
Description
technical field [0001] The present invention relates to a light irradiation device. Background technique [0002] As a conventional light irradiation device, the following device is disclosed in Patent Document 1: it includes a light source, a radiator provided on the back side of the light source, a fan for feeding air to the radiator, and a housing for accommodating them. A plurality of radiating fins arranged at intervals is configured, and a partition plate is attached to a predetermined surface of the radiating body to adjust a flow path of air flowing in a gap between the respective radiating fins. [0003] However, in this light irradiation device, it is necessary to separately prepare the partition plate and install it in the case, so there is a problem that the weight and manufacturing cost of the whole device increase. In addition, in such a light irradiation device, it is necessary to arrange the electric wires for supplying electric power to the light source in ...
