Automotive headlamps

摘要

An automotive headlamp is provided with: a light-emitting module; a control circuit unit configured to control the lighting of the light-emitting module; a support substrate configured to support both the light-emitting module and the control circuit unit; and a reflector configured to reflect, through an inner surface of the reflector, light emitted by the light-emitting module and collect the reflected light. The support substrate is arranged in a manner such that the control circuit unit is positioned in a region outside the reflector.

1. An automotive headlamp comprising:
a light-emitting module including a light-emitting section and a sub-mount on which the light-emitting section is mounted; a control circuit unit spaced apart from the light-emitting module and configured to control the lighting of the light-emitting module; a support substrate configured to support both the light-emitting module and the control circuit unit; a reflector configured to reflect, through an inner surface of the reflector, light emitted by the light-emitting module and collect the reflected light; an electrically conductive member that electrically connects the light-emitting module and the control circuit unit; and a housing mounted on the support substrate, wherein the support substrate is arranged in a manner such that the control circuit unit is positioned in a region outside the reflector, wherein the electrically conductive member is connected from a portion of the electrically conductive member connected to the control circuit unit to the light-emitting module, through an installation path that leads to a point more forward in a light-concentrating direction of the reflector than the light-emitting module, in a manner such that a light path of light, collected by the reflector, out of the light emitted by the light-emitting module is avoided, and wherein the electrically conductive member is supported by the housing in a manner such that when the housing is mounted on the support substrate, a portion thereof, which is led from at least a neighborhood of the control circuit unit to the point more forward in the light-concentrating direction of the reflector than the light-emitting module, is led to the installation path.
