AUTOMOTIVE HEADLAMP, HEAT RADIATING MECHANISM, LIGHT-EMITTING APPARATUS AND LIGHT SOURCE FIXING MEMBER

摘要

In an automotive headlamp, a light-emitting module is configured such that a light-emitting element and a control circuit unit for controlling the lighting of the light-emitting element are structured integrally with each other. A control circuit unit in a position anterior to the light-emitting element in a lamp unit is located below a shade section so that the control circuit unit can be clear of the path of light used to form a low beam light distribution pattern of the light emitted by the light-emitting element. In this setting, the light-emitting element is so located that a main optical axis Ax2 is perpendicular respect to an optical axis Ax1 of the lamp unit and that a light-emitting portion of the light-emitting element protrudes higher than the control circuit unit in the direction of the main optical axis Ax2.

1. A heat radiation mechanism comprising: a first heat radiation member configured to radiate heat of a light source; and a second heat radiation member configured to radiate heat generated by a control circuit board for controlling the lighting of the light source, the second heat radiation member being placed such that the second heat radiation member overlaps with at least part of the first heat radiation member as viewed from a first direction parallel to the control circuit board, wherein the first heat radiation member is placed such that the first heat radiation member overlaps with at least part of the control circuit board as viewed from a second direction perpendicular to the control circuit board.
