Embodiment Construction

[0026] 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.

[0027] Figure 1 and figure 2 An example of the configuration of a vehicle lamp 10 according to an embodiment of the present invention is shown. FIG. 1 shows a perspective view of a vehicle lamp 10; figure 2 It shows a cross-sectional view of the vehicle lamp 10 formed by a horizontal plane crossing each light source unit 20 in the middle. 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 vehicles such as automobiles, which irradiates light to the front of the vehicle, and has: a plurality of light source units 20, a cover...

Abstract

A vehicular lamp used in an automobile, includes: a light source module for generating light; and an optical member for directing the light generated by the light source module forward. The light source module includes: a semiconductor light-emitting element or device for generating light; a fluorescent member for emitting light in accordance with the light generated by the semiconductor light-emitting element, the fluorescent member covering a surface of the semiconductor light-emitting element; and a light-blocking member, formed to be opposed to the semiconductor light-emitting element with the fluorescent member sandwiched therebetween and cover a side of the semiconductor light-emitting element and a part of the fluorescent member, for blocking a part of the light generated by the semiconductor light-emitting element and a part of the light emitted by the fluorescent member.

Description

technical field [0001] The invention relates to a vehicle lamp and a light source module, in particular to a vehicle lamp and a light source module for vehicles. 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 using mirrors or lenses (for example, refer to Patent Document 1). [0003] (Patent Document 1) [0004] Japanese Patent Application Laid-Open No. 6-89601 (pages 3-7, Figures 1-14). [0005] When optically designing the light distribution pattern of automotive lamps, sometimes the shape of the light source must be considered. In addition, when a semiconductor light emitting element is used in a vehicle lamp, the semiconductor light emitting element emits light from a light source having a predetermined enlargement as the entire surface. Therefore...
