SUMMARY OF THE INVENTION The present invention solves the above-mentioned conventional problems, and can easily position and fix a light-emitting element in a substantially horizontal lateral direction with respect to a substrate, without requiring any separate parts. It is an object of the present invention to provide a light-emitting element mounting structure capable of reducing the number of components and reducing costs and reducing the number of production steps.

[0006]

In order to achieve the above object, according to the first aspect of the present invention, there is provided a light emitting device in which a main body of a light emitting element is mounted on a substrate in a vertical direction substantially perpendicular to the substrate. In the mounting structure of the element, it is preferable that a protruding portion for inserting and positioning and fixing the main body of the light emitting element to the substrate when the main body of the light emitting element is in a horizontal direction substantially parallel to the substrate is provided on the tip side of the light emitting element.

BRIEF DESCRIPTION OF THE DRAWINGS FIG. 1 is a perspective view showing an embodiment of a light emitting device mounting structure according to the present invention. FIG. 1 is a side view showing a mounting structure of the light emitting device according to the first embodiment of the present invention.

As shown in FIG. 1, the mounting structure of the light emitting element of the first embodiment is such that a main body 3 of the light emitting element 2 is mounted on a front end side of the light emitting element 2 mounted vertically in a direction substantially perpendicular to the substrate 1. When the substrate 1 is turned sideways substantially parallel to the substrate 1, an acute-angled projection 5 is provided to be inserted into an acute-angled concave hole 4 formed in the substrate 1 for positioning and fixing. Therefore, when the light emitting element 2 is set in the vertical direction substantially parallel to the substrate 1, the projection 5 of the light emitting element 2 is inserted into the concave hole 4 of the substrate and is positioned and fixed. Since it can be easily positioned and fixed in a substantially horizontal horizontal direction and does not require a separate component, the number of components can be reduced, the cost can be reduced, and the number of production steps can be reduced.

Furthermore, since the projection 5 provided on the light emitting element 2 is formed in an acute angle shape, when the light emitting element 2 is turned sideways substantially parallel to the substrate 1, the acute angle projection 5 is formed. The light emitting element 2 can be smoothly inserted into the concave hole 4 formed in the substrate 1 and the positioning and fixing of the light emitting element 2 can be easily performed.

FIG. 2 is a side view showing a mounting structure of the light emitting device of the second embodiment. As shown in FIG. 2, the mounting structure of the light emitting element according to the second embodiment is such that, when the light emitting element 2 is provided with an acute-angled protruding portion 5 on the base side of the light emitting element 2 and Then, the protrusion 5 is inserted into the concave hole 4 formed in the substrate 1 so that the light emitting element 2 is positioned and fixed to the substrate 1. The operational effects of the light emitting element mounting structure of the second embodiment are the same as those of the light emitting element mounting structure of the first embodiment described above, and a description thereof will be omitted.

[0011]

As described above, according to the first aspect of the present invention, after the main body of the light emitting element is mounted on the substrate in a vertical direction substantially perpendicular to the substrate, the main body of the light emitting element is mounted on the substrate. When the light emitting device is set in a horizontal direction substantially parallel to the substrate, the protrusion provided on the front end side of the light emitting element is inserted into the substrate and positioned and fixed, so that the light emitting device can be easily positioned and fixed substantially horizontally in the horizontal direction with respect to the substrate. In addition, the number of parts can be reduced without the necessity of separate parts, so that the cost can be reduced and the number of production steps can be reduced. According to the second aspect of the present invention, since the protrusion has an acute angle toward the tip, the protrusion can be smoothly inserted into the substrate.
