Background

The rapid development of society makes vehicles gradually popular, private cars become indispensable transportation means in social life, and car logos of cars are generally arranged on front and rear bumpers of a car body, so that the automobile is attractive and can highlight brands and grades of the vehicles.

The car logo lamp is generally internally provided with LEDs on the light-transmitting mask, the LEDs are used for emitting light, and then the car logo is made to emit light, but the points where the LEDs are located are brighter relative to the gaps, so that the whole car logo lamp is uneven in brightness and visible to naked eyes, commonly called a firefly phenomenon, and meanwhile if the lines of the LEDs are damaged, the car logo lamp is made to appear in a more obvious dark area, and the mark is not complete visually at night.

Disclosure of Invention

In order to solve the technical problems, the utility model provides a miniLED luminous vehicle logo lamp.

The utility model adopts the following technical scheme:

the utility model provides a miniLED luminous car logo lamp, includes the face guard, the rear of face guard is connected back cap, the face guard divide into the face guard that is located the inlayer and is located outer face guard two, face guard two buckle back all around and back with back cap zonulae occludens, face guard one and face guard two junction is sealed, face guard one outwards protrudes and forms the sign, the sign outwards passes face guard two, face guard one's medial surface connecting line board, have the miniLED who arranges corresponding with the sign on the circuit board, miniLED is located the sign outwards protrudes and forms the cavity and evenly distributed.

Preferably, the first mask and the second mask are manufactured into a whole by adopting secondary injection molding, the first mask is made of PMMA material, and the second mask is made of PC+ABS material.

Preferably, a liner is arranged on the outer surface of the second mask.

Preferably, the side wall of the rear shell cover is fixedly connected with the mounting lug.

Preferably, the second face mask and the rear shell cover are subjected to ring vibration friction welding.

Preferably, the circuit board and the first mask are fixed by riveting.

Preferably, the inner surface of the rear housing cover is provided with reinforcing plates, the reinforcing plates are in a crisscross grid shape, the inner surface of the rear housing cover is provided with supporting columns, and the supporting columns are abutted against the circuit board.

Compared with the prior art, the utility model has the beneficial effects that:

the circuit board is arranged on the inner side of the mask, miniLED, miniLED which corresponds to the marks and is uniformly distributed, so that a unit number of point light sources exist in a unit area, light quantity uniformity is basically realized firstly, then light rays of the point light sources are mutually interweaved and reflected in a cavity on the inner side of the marks, and finally, the uniform light effect of the first mask is added, so that the vehicle logo light emits very uniformly; and adopt miniLED to make the car logo lamp lighter and more miniaturized, the pointolite in the car logo lamp can accomplish to closely arrange also makes when appearing individual case pointolite damage, and whole car logo lamp is unlikely to appear dark space on the eye vision impression, guarantees luminous effect.
