[0064] Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings. The same or equivalent components, members, and processes shown in the drawings are assigned the same reference numerals, and overlapping descriptions are appropriately omitted. figure 1 It is an exploded perspective view showing the vehicle lamp 100 of this embodiment. The vehicle lamp 100 includes a lens 10 , a lens bracket 20 , a reflector 30 , a light source module 40 , a heat sink 50 , and a cooling fan 60 , and each component is positioned relative to each other and fixed by a fixing unit not shown.

[0065]The lens 10 is made of a translucent material, and is used to irradiate light from the light source module 40 in a predetermined light distribution to the front. The lens holder 20 is a member for holding the lens 10 while maintaining the relative positional relationship between the light source module 40 and the reflector 30 . The reflector 30 is a ...

[0104] Next, use figure 2 A second embodiment of the present invention will be described. The description of the content overlapping with the first embodiment is omitted. In this embodiment, it is also applicable without using the ADB technology. The configuration of the vehicle lamp 100 and the configuration of the light source module 40 are the same as those of the first embodiment, and description thereof will be omitted.

[0105] Figure 9 is a graph showing combined luminance from adjacent light emitting elements 43c in this embodiment, Figure 9 (a) is an example showing that the distance of the light emitting element 43c is long and the combined brightness is insufficient, Figure 9 (b) is an example showing that the distance between the light emitting elements 43c is short and the combined luminance is sufficient. The horizontal axis in the figure shows the position along the long-side direction of the subassembly 43 , and the vertical axis shows the brightness. ...

Abstract

The invention provides a light source module which can mount a light-emitting element at a high density and suppress generation of glare and a lighting fixture for vehicles. This light source module (40) is provided with: a plurality of light emitting elements (43c); a plurality of metal wires (45a) which separately supply electric power to the light emitting elements (43c), respectively; a light-reflecting resin part (43d) which seals at least a part of the lateral surface of each light emitting element (43c); and a light-absorbing resin part (45) which seals the metal wires (45a).

Description

technical field [0001] The present invention relates to a light source module and a vehicle lamp, in particular to a light source module and a vehicle lamp in which a plurality of light emitting diodes are arranged on the surface of a component mounting substrate. Background technique [0002] Car lamps can generally switch low beam and high beam. The low beam illuminates the vicinity with a predetermined illuminance, and the light distribution regulations are determined to prevent glare from oncoming vehicles and preceding vehicles, and are mainly used when driving in urban areas. On the other hand, the high beam illuminates a large area and a distance ahead with a relatively high illuminance, and is mainly used when the oncoming vehicle or the road with few preceding vehicles is traveling at a high speed. Therefore, the high beam is better for the driver's visibility than the low beam, but has a problem in that it gives glare to the driver of the vehicle and pedestrians e...
