Background

In order to facilitate the identification of the turn signal by road users, the color of the light of the turn signal is required to be amber in the regulations GB 4785-2007_ automobile and trailer exterior lighting and light signal device installation. The steering lamp light source is provided with a bulb and an LED, the bulb is divided into PY21W/W21W and the like according to a base to realize the function of the steering lamp, and the LED also has various types to meet the legal requirements of the steering lamp.

In recent years, with the development of LED light source technology and the reduction of cost, the application in the automobile lamp is more and more extensive and various, and meanwhile, some technical barriers are broken through, so that more choices exist in the modeling. In the current vehicle model in the market, in order to meet the amber color requirement of the rear steering lamp, a colorless transparent mask or a pink transparent mask is mostly adopted, however, the functions of the rear position lamp, the brake lamp, the rear fog lamp, the rear retro-reflector and the like can all adopt a red transparent mask to realize corresponding functions, so that the problem of inconsistent colors of the rear lamp is caused, and the modeling of the rear lamp is often limited.

Disclosure of Invention

In order to solve the problem that the existing rear steering lamp cannot adopt a red transparent mask, the utility model provides the rear tail lamp of the passenger car integrated with the rear steering lamp, so that the color consistency of the mask of the combined lamp is improved, the strong plastic feeling brought by the colorless transparent mask is avoided, and more choices are provided for the modeling design.

The utility model is realized by adopting the following technical scheme:

a rear tail lamp of a passenger car integrated with a rear steering lamp comprises a rear steering lamp A, a rear return emitter B, a rear fog lamp C and a reversing lamp D, wherein the rear steering lamp A, the rear return emitter B, the rear fog lamp C and the reversing lamp D share a face mask; the mask is a red transparent mask 3; the rear steering lamp A comprises a rear steering lamp LED light source 1 and a thick-wall light guide 2, the rear steering lamp LED light source 1 comprises a mounting support and LED particles fixed on the mounting support, and the LED particles are pure yellow LED particles.

Further, the thick-walled light guide adopts a colorless transparent thick-walled light guide made of a PC material, and the transmittance of the thick-walled light guide is 0.6.

Further, the LED particles adopt pure yellow LED particles with the wavelength of 584-588nm, and the power of the LED particles is 0.5W.

Further, the number of the LED particles is 19.

Further, the red transparent mask 3 is made of 2.5mm PMMA material, and the transmittance thereof is 0.75.

The utility model has the following beneficial effects:

the novel LED particles are innovatively applied, so that light rays can reach the amber color requirement through the red transparent mask, and if the novel LED particles are applied to a rear fog lamp and a rear retro-reflector assembly combined lamp of a high-vehicle model, the colors of the masks in a rear steering lamp area and other function lamp areas are unified, the shape is more integral, and the lighting point of the whole vehicle shape is improved.
