Detailed Description
The principles and features of the present invention are described below in conjunction with the following drawings, the examples given are only intended to illustrate the present invention and are not intended to limit the scope of the present invention. The invention is described in more detail in the following paragraphs by way of example with reference to the accompanying drawings. The advantages and features of the present invention will become more fully apparent from the following description and appended claims. It should be noted that the drawings are in simplified form and are not to precise scale, and are provided for convenience and clarity in order to facilitate the description of the embodiments of the present invention.
As shown in fig. 1 to 3, the present invention provides a low-angle dipped headlight lamp, comprising a light source 1, a lens body 2 and a housing 3, wherein a cavity 31 is formed in the housing 3, the light source 1 comprises a back plate 11 and an LED lamp 12 mounted on the back plate 11, the back plate 11 is mounted on the upper portion of the cavity 31, the LED lamp 12 is mounted on the lower end of the back plate 11, a light source groove 21 is formed on the upper end of the lens body 2, the LED lamp 12 is mounted in the light source groove 21, the lens body 2 has a first reflecting surface 22, a second reflecting surface 23 and an emitting surface 24, the first reflecting surface 22 is a smooth plane and is horizontally disposed on one side of the light source groove 21, the second reflecting surface 23 is a smooth curved surface and is disposed on the other side of the light source groove 21, and the height of one end of the second reflecting surface 23 far away from the light source groove 21 is lower than the height of the first reflecting surface, two ends of the emergent surface 24 are respectively connected with one end of the first reflecting surface 22 far away from the light source groove 21 and the lower end of the second reflecting surface 23, light rays of the LED lamp 12 positioned in the light source groove 21 and irradiated on the first reflecting surface 22 are totally reflected on the first reflecting surface 22 and then emitted from the upper part of the emergent surface 24, light rays irradiated on the second reflecting surface 23 are reflected by the second reflecting surface 23 and then emitted from the lower part of the emergent surface 24, and the rest light rays are directly emitted from the emergent surface 24.
When the LED lamp is turned on as a light source, light is emitted from the light source groove, because the first reflecting surface is horizontally arranged at one side of the light source groove, therefore, when the light irradiates the first reflecting surface, the light is totally reflected and emitted from the upper part of the emergent surface to irradiate a position far away from the vehicle lamp, because the second reflecting surface is a smooth curved surface and is arranged at the other side of the light source groove, and the height of one end of the second reflecting surface far away from the light source groove is lower than that of the first reflecting surface, therefore, the light irradiated on the second reflecting surface is reflected by the second reflecting surface and then is emitted from the lower part of the emergent surface and irradiates to a position close to the car lamp, meanwhile, light rays which do not irradiate the first reflecting surface and the second reflecting surface are directly emitted from the emergent surface, so that the light rays are directionally and uniformly distributed on the front road surface of the car lamp, the light rays are not scattered upwards, and the vision of a coming car is not influenced.
In order to expand the illumination range of the vehicle lamp, the light source groove 21 is a strip-shaped groove, and the LED lamps 12 are arranged on the back plate 11 in parallel along the length direction of the light source groove 21.
The housing 3 is attached to a lower portion of a front end or a rear end of the vehicle body.
