Problems solved by technology

Since the light source of the light emitting device generates heat, the temperature of the air inside the housing is relatively high, while the outside temperature is relatively low. When the humidity of the air in the housing is relatively high, obvious condensation will occur inside the lens of the light emitting device that is in contact with the outside world. Phenomenon, condensation of water droplets will affect the functionality of the lighting device
Especially in special weather conditions, such as rainy days, when the air humidity is high, condensation will occur more seriously, and the converging water droplets will even cause water to accumulate in the lamp, thereby adversely affecting the electrical performance of electrical components
[0003] In order to intervene in the phenomenon of fog condensation on car lights, it is known to apply an anti-fog coating on the outer lens or to place a desiccant inside the lighting device, however, it is not cheap to apply an anti-fog coating or to place a desiccant , and more importantly, anti-fog coatings have a limited lifespan and become less effective over time, while leaving desiccants only work for a short period of time
In addition, the existing solutions only belong to the passive defogging technology, which works slowly and cannot intelligently adjust the effectiveness of defogging according to needs.

Embodiment Construction

[0024] Exemplary embodiments of the present invention will be described in detail below with reference to the accompanying drawings, wherein the same 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.

[0025] The embodiments of the present invention illustrate the defogging principle of the light emitting device by taking the LED light source as an example of the light source of the light emitting device of a motor vehicle. In the lighting device of motor vehicles, the LED light source (especially the full LED light source) generates less he...

Abstract

The present invention provides a lighting device for a motor vehicle and a vehicle. The light emitting device has a light source, a casing (1), and a lens (2). The lighting device (100) also has a blowing unit (10), which is used to generate airflow and guide the airflow to components of the lighting device (100). The blowing unit of the lighting device for a motor vehicle of the present invention can efficiently demist the lighting device.

Description

technical field [0001] The present invention relates to the technical field of motor vehicles, in particular to a lighting device for a motor vehicle and a vehicle with the lighting device. Background technique [0002] Lighting devices for motor vehicles include various lighting and / or signaling devices, such as vehicle headlights, fog lights, turn signals, brake lights, position lights, daytime running lights, and the like. The basic structure of the light emitting device includes a housing, a light source, a light distribution element and a lens, wherein the light source and the light distribution element are located in the space formed by the housing and the lens. In modern headlight design, defogging needs to be considered. Fog condensation will affect the light transmission performance of the lens to a certain extent, and then affect the optical performance of the light emitting device. Physically, water droplets form when the temperature of the air drops below the c...
