Problems solved by technology

The LED light source includes LED chips. Due to the low luminous power of a single LED chip, its luminous brightness is relatively weak for lighting devices such as automobile headlights, and the luminous direction is scattered, the brightness is uneven, and the light concentration is poor.
And for different standards of car lights, the light angle cannot be adjusted practically. Each car light needs to be specially set for the structure of the car light source, and it cannot well meet the lighting standards of the car lights

Embodiment Construction

[0031] In order to better explain the present invention, a preferred embodiment is used to illustrate the present invention in detail with the accompanying drawings. The details are as follows:

[0032] Such as figure 1 As shown, the LED automobile light source provided by the present invention includes an LED automobile wick 1 and a lamp holder 2, and the LED automobile wick 1 is fixedly connected to the lamp holder 2. The LED automobile light source also includes a lamp post 3 and a lamp shade (not shown in the figure). Wherein, the lamp post 3 is a hollow cylinder, the LED automobile wick 1 is sleeved and installed on the upper part of the lamp post 3, and the lower part of the lamp post 3 is connected with the lamp holder 2. The lampshade is connected with the lamp holder 2 and the LED car wick 1 and the lamp post 3 are sealed in the lampshade. In addition, a radiator 21 is provided on the lamp holder 2, and a plurality of heat exhaust holes 211 are provided on the radiator ...

Abstract

The invention provides an angle-adjustable LED automobile lampwick and an LED automobile light source. The angle-adjustable LED automobile lampwick comprises a plurality of LED lamps, and the anodal substrate and the cathodic substrate of each LED lamp deflect by different angles relative to the vertical plane of a lamp holder to form different illuminating angles of LED chips. When the angle-adjustable LED automobile lampwick serves as a dipped headlight, part of the LED lamps, serving as main light sources, form a light center at the central point of a light cut-off line, and the other part of the LED lamps, serving as supplemental light sources, form residual light distributed under the light cut-off line and the left side and the right side of the light center; when the angle-adjustable LED automobile lampwick serves as a headlight on full beam, part of the LED lamps, serving as the main light sources, form a light center pointing to one point, and the other part of the LED lamps, serving as supplemental light sources, form residual light which form a fan-shaped light ring at the periphery of the light center. The LED automobile light source provided by the invention is uniform in brightness and relatively good in light focusing; different lighting angles can be set according to different headlight standards; the light types of light emitters can be well complementary to better meet the headlight illumination requirement.

Description

Technical field [0001] The present invention relates to the technical field of lighting devices, in particular to a vehicle LED lighting lamp with an adjustable angle. Background technique [0002] LED (Light Emitting Diode) is a semiconductor element that can convert current into light in a specific wavelength range. With its advantages of high luminous efficiency, small size, light weight, and environmental protection, it has been widely used in various fields at present. [0003] A vehicle lamp structure using LED as a light-emitting body generally includes an LED light source, a reflective cover, a shading part, and a projection lens. The LED light source includes LED chips. Since a single LED chip has low luminous power, the luminous brightness of lighting devices such as automobile headlights is relatively weak, and the luminous direction is scattered, the brightness is uneven, and the light concentration is poor. In addition, the light-emitting angles of car lights of diffe...
