Description
Technical Field
The utility model relates to an automobile lamp field, concretely relates to direct-injection type side-emitting LED device's automobile lamp.
Background
At present, the automobile lamp mainly adopts an LED as a light source, and comprises a common direct-injection type, a reflection cavity type, a light guide type and other realization forms. However, these implementations have the following drawbacks: firstly, the common direct-injection type is difficult to create a three-dimensional effect and is suitable for plane modeling. Secondly, the reflective type is difficult to make a narrow and distorted modeling effect, and is suitable for a light emitting area with a medium area. And thirdly, the light guide type head light inlet area and the tail light outlet area both need space shielding, and the light guide type head light inlet area and the tail light outlet area are suitable for modeling with larger space.
Therefore, in order to utilize a smaller space and satisfy the requirement of a new and more diverse model, it is urgently needed to develop a novel car lamp with a small occupied space.
SUMMERY OF THE UTILITY MODEL
In order to overcome the defects, the to-be-solved technical problem of the utility model is to provide an automobile lamp which is easy to make three-dimensional modeling and occupies a small space.
The technical proposal of the utility model is that the automobile lamp with the direct-injection type side-emitting LED structure comprises an LED circuit board and an external lens,
the car lamp comprises a laterally arranged LED circuit board fixed on the bracket, a discrete material light-emitting surface arranged in front of the LED light-emitting direction and an external lens positioned in front of the discrete material light-emitting surface; and the LED circuit board is provided with a side light-emitting LED.
The LED circuit board comprises a side-emitting LED, an FR4 board and necessary electronic components.
And the light emitting surface of the side light emitting LED is positioned on the side surface of the LED.
Further, the side-emitting LEDs are arranged on two sides or one side of the LED circuit board.
And the discrete material light-emitting surface corresponds to the side light-emitting LED.
Further, the side-emitting LEDs are uniformly arranged on the LED circuit board.
Wherein, a decorative ring is arranged on one side of the circuit board.
The LED circuit board is detachably arranged on the support.
The light emitting surface of the discrete material, also called the internal distribution of the discrete material, is a material capable of blurring point light sources, and is characterized by better light dispersion. The decorative ring is made of common plastic and is used for decorating and modeling. The external lens is made of common PMMA and covers the surface of the car lamp.
The utility model discloses a direct-injection type side-emitting LED design. The side-emitting LEDs are arranged on the rear side of the light emitting surface of the discrete material at equal intervals and can be made into a three-dimensional shape, and the side-emitting LEDs can be selectively arranged on two sides or one side of the circuit board, so that the width and the width of the light emitting area are adapted.
Has the advantages that:
the utility model discloses for traditional direct injection formula or reflective LED car light, have higher molding property, required space is little, and traditional realization form has the restriction to three-dimensional space, can only be better satisfy two-dimensional molding, and current trend requirement is three-dimensional effect of lighting. The technology can meet the modeling requirement and achieve the uniform and three-dimensional lighting effect under the complex three-dimensional modeling requirement.
