Description

The self-propelled vehicle combination tail lamp

Technical field

The utility model relates to a kind of signal lamp that is used for self-propelled vehicle, especially relates to a kind of self-propelled vehicle combination tail lamp.

Background technology

Existing self-propelled vehicle combination tail lamp is that steering indicating light, backing-up lamp and brake lamp etc. are organically gathered together, and makes the self-propelled vehicle profile clean and tidy, attractive in appearance.Polychrome face shield technology is extensive use of, make the face shield of combination tail lamp become as a whole, the taillight of modern automobile all uses the combination tail lamp of polychrome face shield basically, the lamp storehouse that difference in functionality is arranged on the housing, cooresponding face shield also has different colors, be equipped with and use different bulbs, to show different functions.Along with the raising of people's living standard, the aesthetic property of back combination tail lamp is more and more paid attention to, and novel, unique personalized product more and more is subjected to consumers in general's favor.Wherein a kind of structure of present disclosed automobile rear taillight is to adopt multiple face mask, is a kind of modification of " Crystal lamp ", and generally, it is water white that one deck is arranged in two face mask, and whole structure is more steady than " Crystal lamp "; Because two face mask are arranged, look that face shield has very big depth, stereoscopic visual effect is fine.But because the existence of Reflex Reflector, the light that sends from light source will be blocked, and this will cause the loss of the luminous energy of dividing outgoing from central division.And brake lamp light distribution requirements central light strength is the highest, and the existence of Reflex Reflector certainly will will have influence on the luminous intensity distribution performance of brake lamp.

Summary of the invention

The purpose of this utility model provides and a kind ofly can make full use of luminous energy, satisfies the good self-propelled vehicle combination tail lamp of requirement of brake lamp luminous intensity distribution and translucent effect.

The utility model is that the technical scheme that achieves the above object is: a kind of self-propelled vehicle combination tail lamp, comprise lamp housing, be installed on the lamp housing and the middle part has the inner cover of Reflex Reflector, outer cover and be installed in brake lamp on the lamp housing, backing-up lamp and steering indicating light, backing-up lamp and steering indicating light are positioned at the bottom of brake lamp, it is characterized in that: described first paraboloid of revolution that its reflecting surface of lamp housing of brake lamp is installed by the bottom, second paraboloid of revolution on top and constitute along the columniform cylindrical shell of second paraboloid of revolution oral area extension, the radius of curvature R 1 of first paraboloid of revolution and the radius of curvature R 2 of second paraboloid of revolution increase from inside to outside, and the minimum profile curvature radius R1 of first paraboloid of revolution is greater than the minimum profile curvature radius R2 of the second rotation parabolic, first paraboloid of revolution and second paraboloid of revolution are divided into a plurality of trapezoidal reflecting surfaces along its cross section and along the center longitudinal diffusion, and the middle part projection of each trapezoidal reflecting surface, the reflecting surface of described Reflex Reflector inboard are to be made of a plurality of equilateral polygon and the homalographic triangular pyramid that is arranged on each equilateral polygon.

The utility model can cause the problem of dividing the loss of the luminous energy that penetrates from central division at the Reflex Reflector on the inner cover, first paraboloid of revolution and its top second paraboloid of revolution of the paraboloid of revolution on the lamp housing reflecting surface being divided into the bottom, with first paraboloid of revolution and its top second paraboloid of revolution along the cross section and vertically be divided into a plurality of trapezoidal convex globoidal reflecting surfaces, because the minimum profile curvature radius R1 of first paraboloid of revolution is greater than the minimum profile curvature radius R2 of second paraboloid of revolution, therefore first paraboloid of revolution is used for long range diffusion light, can not only be to satisfy the angle of visibility scope, and make the light utilization efficiency at reflecting surface center higher, control the scope of light diffusion simultaneously again by second paraboloid of revolution and convex globoidal reflecting surface, the reflecting surface of mixing Reflex Reflector further is out of shape reflecting surface, make the light diffusion, satisfy light distribution requirements, satisfy the check point luminous intensity distribution, thereby actv. utilizes limited energy, realize multi-region section free form surface directional light distribution, satisfy the requirement of brake lamp luminous intensity distribution, and it is good to have a translucent effect.
