Angle-adjustable LED automobile lampwick and LED automobile light source

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 invention relates to the technical field of lighting devices, in particular to an angle-adjustable LED lighting lamp for vehicles. Background technique [0002] LED (Light Emitting Diode) is a semiconductor element that converts electric 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. [0003] The car lamp structure using LED as the illuminant generally includes an LED light source, a reflective cover, a light-shielding portion and a projection lens. The LED light source includes LED chips. Due to the low luminous power of a single LED chip, the luminous brightness is relatively weak for a lighting device such as a car headlight, and the luminous direction is scattered, the brightness is uneven, and the light concentration is poor. Moreover, for different standard car lights, the light emitting angle...

AI Technical Summary

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
