Problems solved by technology

[0004] However, in the above configuration, the concave portion (or convex portion) that functions as a positioning function for a substrate of a specific size and shape cannot function as a positioning function for a substrate of another size and shape.
Therefore, it is not possible to use one type of heat sink for various boards with different sizes and shapes, and it is necessary to prepare molds for heat sinks for each type of board.
As a result, the overall manufacturing cost of various lighting devices in which substrates differ in size and shape becomes high.

Embodiment Construction

[0016] Such as figure 1 As shown, the lighting device of this embodiment includes: a substrate 11 on which a light emitting element 10 is mounted, a heat dissipation member 2 thermally connected to the substrate 11 , and a mounting member 3 fixed to the heat dissipation member 2 . The mounting member 3 has a positioning hole 310 , and the positioning hole 310 is a through hole in which one opening is closed by the heat dissipation member 2 . The substrate 11 is positioned by the inner peripheral surface of the positioning hole 310 .

[0017] In the lighting device described above, it is preferable to further include a holder 6 fixed to the mounting member 3 to prevent the substrate 11 from falling out of the positioning hole 310 , and the mounting member 3 has a holder positioning portion 36 for positioning the holder 6 .

[0018] In the lighting device described above, it is preferable to provide positioning parts (positioning convex parts 35 (refer to Figure 5 ), position...

Abstract

Provided is a lighting device capable of generally using a heat dissipation part for a plurality of substrates of different sizes. The lighting device includes a substrate (11) mounted with a lighting element (10), a heat dissipation part (2) thermally connected relative to the substrate (11), and a mounting part (3) fixed relative to the heat dissipation part (2). The mounting part (3) includes a positioning hole (310), the positioning hole (310) is a through hole with one side opening closed by the heat dissipation part (2), and the substrate (11) is positioned through the inner periphery of the positioning hole (310). Different from the condition that the substrate (11) is positioned through concave and convex of the heat dissipation part (2), even when sizes and shapes of the substrate (11) are different, the heat dissipation part (2) can also be general.

Description

technical field [0001] The present invention relates to a lighting device, and more specifically, to a lighting device using a light emitting element mounted on a substrate as a light source. Background technique [0002] Conventionally, there has been provided a lighting device including a substrate on which a light-emitting element is mounted and a heat dissipation member thermally connected to the substrate (for example, refer to Japanese Patent Application Publication No. 2012-104257). [0003] In the lighting device described above, the positioning of the substrate with respect to the heat dissipation member is realized by, for example, a concave portion provided on the heat dissipation member into which the substrate fits or a convex portion surrounding the outer periphery of the substrate. [0004] However, in the above configuration, the concave portion (or convex portion) that functions as a positioning for a substrate of a specific size and shape cannot function as...
