Abstract
The invention provides a stop lamp with a full-reflection lens. The stop lamp comprises a support. An inner lens is installed on the support. The full-reflection lens is arranged on the left side of the inner lens. An LED is arranged at the rear end of the full-reflection lens and installed on PCBs. The PCBs are arranged on the two sides of the full-reflection lens. The stop lamp is more uniform in illumination, and light emitted out of the full-reflection lens can seem like more uniform and gentler after passing through the abrasive inner lens. In addition, the LED adopted for the stop lamp has the advantages of being free of time delay in the illuminating process, high in light purity, good in color rendering performance and high in penetrating power. No reflector is arranged, but the stop lamp can completely meet the requirements of light distribution experiments, the structure is more compact, less heat is generated, and a great structural advantage is achieved.
Description
Technical field
The present invention relates to auto parts machinery technical field, especially relate to a kind of Brake lamp of total reflection lens.
Background technology
LED solid-state semiconductor lighting engineering is considered to the strategic power-saving technology of 21 century.China has carried out in the industry the exploitation of LED lighting engineering and has widelyd popularize, and than metal halid lamp (MH), LED lamp has the longer life-span (being greater than 5 times); In addition, LED lamp also has better controllability and light efficiency, can energy-conservation 50% more than.The feature of another green energy resource of LED lamp is the light source mercury that do not contain hazardous substance itself.Optics aspect, the small light source characteristic of LED chip can, than the optimal design that is easier to realize accurate luminous intensity distribution and secondary optics, accurately be controlled the direction of light, light is assigned to fully on the road of required illumination, prevents light pollution and dazzle.LED has advantages of low power consuming.Along with the development of LED lighting engineering, increasing automobile lamp adopts LED.Adopt the car light of conventional bulb generally all to adopt reflector to make scattered light become directional light, be beneficial to illumination, when mounted bulb is placed on to the focus place of reflector.But LED car light is all to utilize the LED light emitting diode matrix of multiple dispersions to realize illumination, even if adopted reflector, also all light emitting diodes all cannot be placed on to the focus place of reflector, therefore must adopt other structure to make scattered light become directional light.
Summary of the invention
The object of this invention is to provide a kind of Brake lamp of total reflection lens, it has good light source diffusivity, the feature of wide-angle irradiation and high lumen degree.When total reflection principle refers to light and enters optically thinner medium by optically denser medium, leave normal refraction, in the time that incidence angle θ is increased to certain situation, fringence prolongs surface and carries out, and refraction angle is 90 °, and this incidence angle is called critical angle.If incidence angle is greater than critical angle, without refraction, all equal backspace optically denser media of light, this phenomenon is called total reflection.This Brake lamp is exactly that light vertical irradiation LED being sent by two total reflection lens is gone out, and by the filtration of lens in a frosted shape, can allow light seem more even, soft.The design utilizes appropriate luminous intensity distribution to efficiently solve the problems such as light type, light extraction efficiency, uniformity, light distribution angle, dazzle and security, provides to accord with the desired luminous intensity distribution of national standard, really realizes environmental protection and green illumination.The employing of total reflection lens can realize very high luminous intensity distribution efficiency, obtains exceeding 90% delivery efficiency.The design combines optical design, mathematical modeling and 3 dimension surface modelings, and rim ray theory.
The invention provides a kind of Brake lamp of total reflection lens, comprise support, interior lens are installed on described support, the left side of described interior lens is provided with total reflection lens, described total reflection lens rear end is provided with LED light emitting diode, described LED light emitting diode is arranged on pcb board, and described pcb board is arranged on two surveys of total reflection lens.
Further improve and be: described LED light emitting diode rear end is provided with hold-down screw, hold-down screw is for being fixed on lamp housing by light emitting diode and pcb board.
Further improve and be: described LED light emitting diode is at least two, and is arranged on respectively the tail end of pcb board.
Further improve and be: the quantity of described hold-down screw is at least two, be arranged on lamp housing rear portion for fixing fog lamp group mould.
The advantage that compared to the prior art the present invention had is: this product illumination is more even, the light coming out from total reflection lens by lens in frosted, can allow light seem more evenly soft.Moreover the LED light emitting diode that adopts of this product have light without time delay, optical purity high, the advantage that colour rendering is good and penetration power is strong.This product does not configure reflector, but meets luminous intensity distribution requirement of experiment completely, and compacter in structure, heat generation is little, has very strong structural advantage.
Accompanying drawing explanation
Fig. 1 is that master of the present invention looks cutaway view.
Fig. 2 is top view of the present invention.
Wherein: 1-support, lens in 2-, 3-total reflection lens, 4-LED light emitting diode, 5-PCB plate, 6-hold-down screw.
The specific embodiment
In order to deepen the understanding of the present invention, below in conjunction with embodiment, the invention will be further described, and this embodiment only, for explaining the present invention, does not form limiting the scope of the present invention.
As Fig. 1, shown in 2, the present embodiment provides a kind of Brake lamp of total reflection lens, mainly comprise the
interior lens2 of optimizing light type, with a
total reflection lens3 of fitting up and down, two
total reflection lens3 are fixed together by the little buckle on both sides,
total reflection lens3 ends are respectively equipped with 9 LEDs
light emitting diodes4 up and down, each LED
light emitting diode4 distributes a kind of light of rectangle communication mode by coupled surface above: first surface is a periphery, it allows the diffusion of light at two different directions, second surface is in order to calibrate all light, then by all light vertical irradiations that come out on patterned surface above, the light type of going out from patterned surface is after the optimization of interior lens, seem more evenly soft, allow very bright Brake lamp originally seem not dazzling, improve security.
