Embodiment Construction

[0024] Hereinafter, the present invention will be described through the embodiments of the invention, but the following embodiments are not limited to the scope of the present invention, and combinations of all the features described in the embodiments are not necessarily essential to the solutions of the invention.

[0025] figure 1 with figure 2 An example of the structure of a vehicle lamp 10 according to an embodiment of the present invention is shown. figure 1 It shows a perspective view of the vehicle lamp 10; figure 2 A horizontal cross-sectional view of the vehicle lamp 10 formed by a horizontal plane traversing the middle section of the light source unit 20 is shown. The purpose of this example is to form the light distribution pattern of the vehicle lamp 10 with high precision. The vehicle lamp 10 is, for example, a vehicle headlight (headlight) used for a vehicle such as a motor vehicle, and irradiates light to the front of the vehicle. It has: a plurality of l...

Abstract

A vehicular lamp used in a vehicle includes a semiconductor light emitting element for producing light, a sealing member formed of a material, through which the light passes, for sealing the semiconductor light emitting element, a fixing member for fixing the semiconductor light emitting element by fitting an apparent position of one side of the semiconductor light emitting element when viewed through the sealing member into a reference position to which the semiconductor light emitting element is to be attached, and an optical member for forming at least a part of a cut line, which determines a boundary between bright and dark of a light distribution pattern of the vehicular lamp, by projecting a shape of the one side of the semiconductor light emitting element out of the vehicular lamp.

Description

technical field [0001] The invention relates to a vehicle lamp, in particular to a special vehicle lamp. Background technique [0002] From the viewpoint of safety, it is sometimes necessary to form a light distribution pattern with high precision in automotive lamps such as automotive headlights. This light distribution pattern is formed by, for example, an optical system composed of reflective mirrors or lenses (for example, refer to Patent Document 1). In addition, the use of semiconductor light-emitting elements as light sources in automotive headlights is currently being studied. [0003] (Patent Document 1) [0004] Japanese Patent Application Laid-Open No. 6-89601 (pages 3-7, Figures 1-14). [0005] In optical design for forming a light distribution pattern, it is sometimes necessary to consider the shape of the light emitting region of the light source. In addition, the semiconductor light emitting element emits light from a light emitting region having a predete...
