Embodiment Construction

[0027] figure 1 with 2 A semiconductor light module 1 with the features of the invention is shown in different perspective views. The semiconductor light module 1 has an array composed of a plurality of semiconductor light emitting elements 10 , and the semiconductor light emitting elements 10 can be used to realize the main light function of the headlight, such as low beam or high beam. In this case, the semiconductor light module 1 is intended to be accommodated in a housing for a headlight for a vehicle.

[0028]As a carrier component and in order to fulfill the function of the base body, the semiconductor light module 1 has a heat sink 11 with a base section 12 having a receiving side 12 a for receiving the semiconductor light-emitting element 10 . The base section 12 extends over a plane and on the cooling side 12 b of the cooling body 11 opposite the receiving side 12 a is formed a cooling structure 13 which has sheet-shaped cooling fins. Furthermore, the heat sink 11...

Abstract

A semiconductor light module with at least one semiconductor light source and with a cooling body. The cooling body has a base section with a mounting side on which is mounted the semiconductor light source. The base section has a cooling side on which is arranged a cooling structure. A blowing unit is provided, which produces a forced convection of the cooling structure with blown air stream. An inventive deflection channel is provided and it is designed in such a manner that a deflection of the blown air stream by at least 90 DEG between the air outlet direction of the blown air stream from the blowing unit and a flow direction of the blown air stream through the cooling structure are produced.

Description

technical field [0001] The invention relates to a semiconductor light module having at least one semiconductor light-emitting element and a heat sink, wherein the heat sink comprises a base section with a receiving side on which the semiconductor light-emitting element is accommodated, and The base section has a cooling side, on which a cooling structure is formed, and a blower unit is provided which produces a forced convection of the cooling structure with blower air. Background technique [0002] A semiconductor light module is known from DE 10 2010 002 664 A1, which has a semiconductor light-emitting element and is accommodated in such a way that it is arranged directly on the accommodation side of the heat sink. The receiving side is formed on the base section of the heat sink, and the cooling structure is located in the form of ribs on the cooling side opposite the receiving side of the base section. However, the semiconductor light module formed in this way has a lar...
