Technical Field

The utility model relates to a car light lighting technology field especially relates to a LED reflection type grading homogeneity improves structure.

Background

At present, in an automobile lighting lamp using an LED reflection type, a reflection type light emitting mode needs to reflect direct light of the LED through a reflector to meet the requirement of a light emitting effect, and because the LED emits light with a middle vertical angle, the light is strong, and other angles are relatively weak, the edge position of the reflection type light emitting effect is relatively poor.

Therefore, the light emitting form of the light source has an important influence on the actual light emitting quality of the lamp with the reflective light emitting effect.

Therefore, it has been very difficult to improve the light emission form of the light source itself with a simple structure and at a low cost.

SUMMERY OF THE UTILITY MODEL

The utility model discloses a solve the relatively poor problem of reflective luminous effect border position, the utility model provides a LED reflective grading homogeneity improves structure, including LED light source, interior lamp shade, PCB board and speculum, be fixed with in proper order on the PCB board the LED light source interior lamp shade with the speculum, the installation cavity has been seted up on the interior lamp shade, be equipped with the decorative pattern structure on the internal surface or the surface of installation cavity, the LED light source faces the installation cavity.

Preferably, the PCB board is provided with a groove, the side edge of the inner lampshade is provided with a buckle, and the buckle and the groove are matched and installed to fix the inner lampshade on the PCB board. The structure of buckle is adopted, and the lamp shade is installed on the PCB board in making things convenient for, also conveniently dismantles interior lamp shade.

Furthermore, the installation cavity is spherical, and the spherical installation cavity is arranged in a protruding mode towards the direction far away from the PCB. The spherical installation cavity is matched with the pattern structure to ensure that the light is emitted by 180 degrees and is uniform in light emission, and the pattern structure diffuses light.

Preferably, the inner lampshade is of an integrated structure made of transparent plastic materials.

Further, the reflector is bowl-shaped, an opening of the bowl-shaped reflector faces the LED light source, and the LED light source is flush with the opening of the reflector. The light emitted by the LED light source is diffused into the reflector after passing through the inner lampshade, so that the luminous effect of the reflector is more uniform.

Preferably, the LED light source faces the center of the bowl-shaped reflector. The LED light source is over against the center of the reflector, so that the light-emitting effect at each position of the reflector is more uniform.

Further, the reflector is fixed on the PCB through bolts.

Has the advantages that: the utility model discloses have small, with low costs, simple structure, simple to operate, make the reflection effect more even, guaranteed optical quality.

Example 1

The utility model provides a structure is improved to LED reflection type grading homogeneity, includes LED light source 1.1, interior lamp shade 2, PCB board 1 and speculum 3, be fixed with in proper order on the PCB board 1 LED light source 1.1 interior lamp shade 2 with speculum 3, installation cavity 5 has been seted up on interior lamp shade 2, be equipped with decorative pattern structure 2.1 on the internal surface or the surface of installation cavity 5, LED light source 1.1 faces installation cavity 5.

The PCB board 1 is provided with a groove, the side edge of the inner lampshade 2 is provided with a buckle 4, and the buckle 4 is matched with the groove to be installed and used for fixing the inner lampshade 2 on the PCB board 1. Adopt buckle 4's structure, make things convenient for interior lamp shade 2 to install on PCB board 1, also conveniently dismantle interior lamp shade 2.

The installation cavity 5 is spherical, and the installation cavity 5 is arranged in a protruding mode in the direction far away from the PCB board 1. The spherical installation cavity 5 is matched with the pattern structure 2.1 to ensure that the light is emitted by 180 degrees and is uniform, and the pattern structure 2.1 diffuses light.

The inner lampshade 2 is of an integrated structure made of transparent plastic materials.

The reflector 3 is bowl-shaped, the opening of the reflector 3 faces the LED light source 1.1, and the LED light source 1.1 is flush with the opening of the reflector 3.
