Embodiment Construction

[0029] Exemplary embodiments of the present invention will be described in detail below with reference to the accompanying drawings, wherein the same or similar reference numerals represent the same or similar elements. In addition, in the following detailed description, for purposes of explanation, numerous specific details are set forth in order to provide a comprehensive understanding of the embodiments of the present disclosure. It may be evident, however, that one or more embodiments may be practiced without these specific details. In other instances, well-known structures and devices are shown in diagrammatic form to simplify the drawings.

[0030] For lighting devices used in motor vehicles, the reflector is a component that is easily affected by the heat radiation of the light source because it is close to the light source bulb. Especially when the light source uses a general halogen bulb, the light source generates a lot of heat and the reflector is damaged. happens ...

Abstract

The invention provides a light-emitting device (1) for a motor vehicle. The light-emitting device (1) comprises a light source (13), and further comprises a reflector (14), the reflector (14) is provided with a first end adjacent to the light source (13) and a second end opposite to the first end, the first end is provided with an end face (143), and the end face (143) is oriented to be deviate from the light-emitting portion of the light source (13). The invention further provides the motor vehicle comprising the light-emitting device. According to the light-emitting device for the motor vehicle, heat damage to a reflecting element can be reduced, and light loss is small.

Description

technical field [0001] The present invention relates to the technical field of motor vehicles and lighting devices, in particular, to a lighting device for a motor vehicle and a motor vehicle including the lighting device. Background technique [0002] The light emitting devices of motor vehicles include various lighting and / or signal indication devices, such as vehicle headlights, fog lights, turn signals, brake lights, position lights, daytime running lights, etc., the basic structure of the light emitting devices is generally Including housing, light source, light distribution element and lens. Due to the existence of the light source, a large amount of heat radiation will inevitably act on the components of the light emitting device, and long-term radiation exposure will cause problems such as aging of the components, degradation of optical performance, thermal damage of the components, and shortened service life. The light distribution element is used to guide or modul...
