Background

At present, a signal lamp is applied to the outside of an automobile and used as an emergency lamp or a warning lamp, and the signal lamp is generally composed of a lamp shade, an LED lamp panel (comprising an LED lamp) and a lamp holder, wherein the lamp shade is formed by manufacturing a plurality of single lenses through an injection molding process, the single lenses are all penetrating convex lenses, and when light rays emitted by the LED lamp on the lamp panel pass through convex curved surfaces of the lenses, the light rays are refracted and condensed. However, due to the limitation of the convex curved surface structure and the lens mode of the lens, the problems of low light emitting utilization rate (namely light emitting efficiency) of the LED lamp, thick whole lampshade, small light condensing and emitting angle (generally 65-85 degrees), obvious yellow edge at the light spot edge and the like exist, and the signal effect of emergency warning is affected.

Disclosure of Invention

The utility model aims to overcome the defects and provide the ultrathin high-concentration LED signal lamp which has high light emitting utilization rate, large concentration and emission angle and uniform light spots.

The aim of the utility model is realized by the following technical scheme: the ultrathin high-concentration LED signal lamp comprises a lamp shade, an LED lamp panel and a lamp holder, wherein the lamp shade consists of a plurality of single lenses, the front of each single lens is an arc-shaped convex curved surface, and the periphery of each single lens, which surrounds the arc-shaped convex curved surface, is a tooth-shaped convex curved surface which is spread in a circumferential array.

The shape of the single lens is square with arc periphery. The periphery of the lamp shade is provided with a convex thin wall, and the periphery of the lamp holder is provided with a groove matched with the convex thin wall.

After the structure of the utility model is adopted, the light-emitting efficiency is improved and the effect of uniform light spots is achieved due to the penetrating light condensation of the arc-shaped convex curved surface and the refraction and reflection light condensation of the tooth-shaped convex curved surface of the single lens; the convex curved surface of tooth form of the diffusion arrangement of the circumferential array expands the light-gathering emission angle to 125-135 degrees, and reduces the dead angle range. The square structure of the single lenses reduces the interval between the single lenses, and can accommodate more on the lampshade; the tooth-shaped convex curved surface of the circumferential array is refraction and reflection type condensation, the projection area of the LED lamp panel is enlarged, the height of a single lens is effectively reduced, the LED lamp panel has the advantages of high light emitting utilization rate, large condensation and emission angle, uniform light spots and the like, the ultra-thin characteristic is realized more obviously, and the high requirements of warning and emergency signal lamps can be met. Interference fit between the peripheral protruding thin wall of lamp shade and the recess of lamp stand has promoted production efficiency and has waterproof dustproof effect concurrently when reducing the signal lamp height.
