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. An automotive headlamp comprising:
a light-emitting module configured such that a light source and a control circuit unit for controlling the lighting of the light source are structured integrally with each other; and a reflector having a reflecting surface for reflecting light emitted from the light source and collecting the reflected light, wherein the control circuit unit is disposed in a position anterior to the light source in a lamp unit.
