Description

Light guide type external high-position brake lamp for electric automobile

Technical Field

The utility model relates to an electric automobile car light technical field specifically is an external high-order stop lamp that is used for light guide form on the electric automobile.

Background

The high-order stop lamp is the auxiliary lamp of stop lamp, generally installs on the central line of vehicle rear end, and some install in the upper end of vehicle rear end to vehicle that the rear was gone easily discovers the place ahead vehicle brake, plays the purpose that prevents the rear-end collision accident and takes place. When a vehicle without a high-level brake lamp, especially a car and a mini-car with a lower chassis brakes, the brightness is usually not enough due to the lower position of the rear brake lamp, and drivers of the following running vehicles, especially trucks, buses and buses with higher chassis, are difficult to see at times, so that the hidden danger of rear-end accidents is large.

The existing high-mount stop lamp basically adopts an LED form, compared with a common incandescent bulb, the LED response time is short, the parking distance of a rear vehicle is shortened, and the driving safety can be improved. However, most of the existing high mount stop lamps have a total reflection phenomenon (i.e., when light passes through a circular or other transparent material with a specific shape, the total reflection phenomenon occurs), so that the uniformity of the light is not good.

SUMMERY OF THE UTILITY MODEL

An object of the utility model is to provide an external high-order stop lamp of light guide form for electric automobile is last to solve the current high-order stop lamp that proposes in the above-mentioned background and can take place the total reflection phenomenon mostly, make the not good problem of light homogeneity.

In order to achieve the above purpose, the utility model provides a following technical scheme: the utility model provides an external high-order stop lamp of light guide form for electric automobile is last, includes lens, control panel, light guide and lamp body, the left and right sides all is provided with the light guide buckle in the lamp body, there is the control panel through the screw connection in the lamp body, the control panel is connected with inside pencil and whole lamp pencil, the left and right sides all is provided with the radiator in the lamp body, the radiator joint is on the light guide buckle, there is the electron assembly on the radiator through the screw connection, the left and right sides the light guide is pegged graft between the light guide buckle, the light guide is connected with inside pencil, the LED light source is all installed to the left and right sides in the lamp body, LED light source, radiator, light guide and lamp body constitute optical module, optical module is connected with the control panel through inside pencil, the vibration friction welding has the lens on the lamp body, the lamp body back spiro union has stud.

Preferably, a breathable film is adhered to the lens.

Preferably, a bayonet is fixedly connected to the back of the lamp housing.

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

1) The utility model adopts the side-emitting LEDs, one on the left and the right, the light is transmitted into the light guide from the two sides, and because the light guide is designed with a plurality of light guide teeth, the complete reflection in the light guide is destroyed, so that the light flows out from the surface of the light guide, the light use efficiency is increased, the light uniformity is greatly improved, and the energy is saved;

2) The utility model has the advantages that the lighting speed is extremely high through the LED and the light guide, so that the response time of a subsequent driver is accelerated, and the response time is shortened compared with that of the original lamp, so that the parking distance of a subsequent vehicle is shortened, and the driving safety can be improved; because the LED high-order stop lamp has no filament and is directly converted from electric energy into heat energy, the LED high-order stop lamp is resistant to vibration and impact; the light utilization efficiency is increased, the light uniformity is greatly improved, and the cost is lower than that of a direct-injection type lamp in a long-size high-brake lamp.
