Description

High-heat-dissipation-efficiency driving lamp of electric vehicle

Technical Field

The utility model relates to an use driving lamp that is used for the illumination on the electric motor car, this driving lamp have good heat dissipation and illuminating effect.

Background

The electric vehicle is used as a portable vehicle, and brings convenience for people to go out. The running lamp on the electric vehicle provides convenience for night travelling, and the light source of the early running lamp is an incandescent lamp. The back side of the incandescent lamp is provided with a light-gathering cover, and the light-gathering cover gathers light emitted by the incandescent lamp and shines the front of the vehicle through the lamp cover. The accumulation of light can produce relatively higher temperature, and moreover, the light column that forms is seen through from the middle part position department of lamp shade terminal surface, and this makes when using owing to be heated unevenly, and lamp shade terminal surface's middle part position department part easily yellows to can influence the light transmissivity of lamp shade. In addition, due to the relatively high energy consumption of incandescent lamps and the booming development of LED lamp technology, LED lamps have been used in electric vehicles. The LED lamp is relatively simple to apply and low in energy consumption. For the beauty of vehicles, the existing vehicles are usually provided with an "angel eye" lamp, and the lamp is formed by annularly arranging a plurality of LED lamps, and after being lightened, a bright ring is formed to play a role in decorating the vehicles.

The arrangement of the 'angel eye' lamp is inconvenient, the LED lamp needs to be arranged on a ring piece and then arranged at the corresponding position of the electric vehicle, and the arrangement of the lamp needs certain arrangement cost.

SUMMERY OF THE UTILITY MODEL

The utility model discloses the technical problem who needs the solution: the driving lamp of the electric vehicle with high heat dissipation efficiency is convenient to set, is convenient to form the effect of a 'angel eye' lamp on the driving lamp, basically cannot generate too large preparation cost, and is favorable for dissipating heat of a lampshade.

For solving the technical problem, the technical scheme of the utility model: a driving lamp of an electric vehicle comprises a lamp holder, wherein an installation cavity is formed in the lamp holder, a light-gathering cover is arranged in the installation cavity, an installation hole for installing a bulb is formed in the center of the light-gathering cover, the open end of the light-gathering cover is located at the opening of the installation cavity, and a transparent outer lampshade is connected to the opening of the installation cavity; the inner bottom surface of the outer lampshade is provided with a plurality of protruding light guide strips, the number of the light guide strips is less than that of the inner convex bodies, and the light guide strips are arranged along the radial direction of the inner bottom surface of the outer lampshade and are uniformly distributed along the circumferential direction of the inner bottom surface; in the radial direction of the inner bottom surface of the outer lampshade, the light guide strip is positioned at the inner side of the inner convex body.

In this driving lamp, the light incident surface is towards the bulb on the light guide strip, and the light that the bulb takes place enters into the light guide strip from the light incident surface, and the light guide strip is to the light guide that the bulb sent and is gone into these interior convex body positions department, and interior convex body has certain spatial structure, and light can be by interior convex body reflection and refraction to conduct each other between these interior convex bodies, form an integral aureole, play the decorative effect of "make the eye" lamp. The outer lampshade is in a cover shape, the bottom surface of the outer lampshade is the end surface of the outer lampshade, and light rays penetrate out of the end surface of the outer lampshade. The inner bottom surface is the surface of the outer lampshade facing the light-gathering cover, and the outer bottom surface is opposite to the inner bottom surface.

Furthermore, the light guide grooves with the number consistent with that of the light guide strips are arranged on the light-gathering cover, the light guide grooves correspond to the light guide strips in position one to one, one ends of the light guide grooves stretch into the positions of the light guide strips, and the other ends of the light guide grooves stretch into the mounting holes. The bottom surface of the light guide groove is also a mirror surface, and the bottom surface of the light guide groove can converge part of light to the side surface of the light guide strip, so that the light incidence amount of the light guide strip can be increased, and the light emitting effect of the inner convex body is ensured.

Further, the side of leading to the snoot on the leaded light strip is the ladder face, and this ladder face upwards raises gradually from inside to outside in the footpath of bottom surface in the outer lamp shade. The step surface can adapt to the leading-in of light well, is favorable to the light incidence of bulb to lead to in the light guide strip, has improved the leaded light effect of light guide strip.

Furthermore, a plurality of convex bodies are arranged on the outer bottom surface of the outer lampshade, the convex bodies are uniformly distributed along the circumferential direction of the outer lampshade, and the positions of the convex bodies and the positions of the inner convex bodies on the outer lampshade correspond. The outer convex bodies are arranged, so that light emitted by the inner convex bodies outwards can be refracted again, the brightness of the light ring is compensated, and the continuity of the light ring can be enhanced.

Further, the center lines of the outer convex body and the inner convex body in the radial direction of the bottom surface of the outer lampshade are staggered with each other, and the outer convex body and the inner convex body are arranged in the radial direction of the bottom surface of the outer lampshade. The luminous effect of the formed light ring is further improved, the integral brightness consistency is good, and the decorative effect on the electric vehicle can be enhanced.

Furthermore, the cross sections of the outer convex body and the inner convex body are all isosceles triangles, so that the light reflection and reflection effects are good, and the convex bodies can be conveniently prepared and formed on the outer lamp shade.

Compared with the prior art, the utility model discloses the beneficial effect who has: when the running lamp of the electric vehicle is used, a light ring can be formed on the inner side of the outer edge of the bottom surface of the outer lampshade of the running lamp, and the decorative effect similar to that of a 'angel eye' lamp is achieved, so that the decorative effect of the electric vehicle is good, and the electric vehicle is fashionable. The light ring can be formed only by forming the convex protrusions on the bottom surface of the outer lampshade, the structure is simple, the setting cost is basically not needed, and a good decorative effect can be achieved. Through setting up the leaded light strip to the formation of the ring of light of being convenient for makes the ring of light that demonstrates have certain luminance, can show very obviously on the bottom surface of outer lamp shade, has guaranteed decorative effect. And a part of light is guided into the periphery of the end face of the lampshade, so that when the lampshade is used, the light arrangement of the end face of the lampshade is relatively dispersed, the heat dissipation effect of the lampshade is good, and the end face of the lampshade is not easy to generate dark spots at the middle position to influence the attractiveness and the light transmission effect of the end face of the lampshade.
