Specific embodiment

Advantage of the present utility model is expanded on further below in conjunction with accompanying drawing and specific embodiment.

Refering to Fig. 1 and Fig. 3, respectively illustrate and meet in one preferred embodiment of this utility model luminous intensity distribution inside high-mount stop lamp Structural representation and high-position stop lamp structure schematic diagram.In the embodiment, high-mount stop lamp includes forming high-mount stop lamp foreign steamer Wide lamp body 10, is provided with light source, luminous intensity distribution portion etc. in lamp body 10.Light source is arranged on one using the configuration of LED light source 21 On circuit board 20.And integrally go out the part of light in high-mount stop lamp, one first lens 30 are provided with, are covered on lamp body 10 outward, Its transparent shape, the global formation as high-mount stop lamp and goes out light luminous intensity distribution and is used.Between 20 to the first lens 30 of circuit board, also Including the second lens 40 that luminous intensity distribution is carried out to LED light source 21.Second lens 40 are set towards LED light source 21, are included in which：

- the plane of incidence 41

The plane of incidence 41 is set towards the LED light source 21 on circuit board 20, as the incident illumination for receiving LED light source 21, works as LED After the light transmission plane of incidence 41 that light source 21 sends, just into the inside of the second lens 40.It is preferred that or alternatively, the plane of incidence 41 is recessed Face, the depression direction in recessed face are identical with the light direction of LED light source 21.The setting in recessed face so that what LED light source 21 sent Spuious light becomes more uniform directional light, and directional light diverging incident, and the light intensity of each several part is identical.Most preferably, can be by The recessed face is set to hemispherical, to obtain optimal diffusion even results.

- reflecting surface 42

Jing after the plane of incidence 41, the lasting media interior in the second lens 40 is propagated up to reflection along straightline propagation to incident illumination Face 42.The reflecting surface 42 is fully reflecting surface 42, after incident illumination is received, is totally reflected according to the cloth set direction of reflecting surface 42 itself Incident illumination, for example, angle of reflection can be set to 30 °, 60 ° etc. by user as needed, and different rising angles needs different anti- Firing angle is positioned.The shape of reflecting surface 42 can be straight reflecting surface 42 or convex surface, and the direction of projection is vertical with incident illumination or is in One angle so that the incident illumination after emitted face reflection, its light path changes about 80 ° -100 °, is most preferably 90 °.And the surface of emission It is advantageous in that using convex surface, can further adjusts parallel incident illumination so that light is uniformly arranged in the horizontal direction.

- exit facet 43

It is arranged on the reflection direction of the light after reflected face 42 is reflected, and reflection light is reflected, to outgoing Penetrate the first lens of rear directive 30.The exit facet 43 is last one luminous intensity distribution part of second lens 40 in light path, and which is to reflection Light carries out total transmissivity, does not make the process of light path change.In the embodiment, exit facet 43 is at an angle with vertical direction.Enter The exit facet 43 preferably, refering to Fig. 2, can be configured to the projection that surface has waveform or dentation, emergent light is entered by one step Row diverging is processed, it is ensured that the light intensity uniformity of emergent light.

With above-mentioned with postponing, refering to Fig. 3, circuit board 20, the first lens 30, the second lens 40 can be passed through fastening screw It is installed on lamp body 10, also can be by the assembling of the mounting means such as clamping, rivet hot.

Above-mentioned high-mount stop lamp is may be directly applied on vehicle, is placed in the middle part or top in tailstock portion, there is provided user is equal The high level brake effect of even, banding.

It should be noted that embodiment of the present utility model has preferably implementation, and not this utility model is appointed The restriction of what form, any one skilled in the art are changed or are modified to possibly also with the technology contents of the disclosure above Same effective embodiment, as long as without departing from the content of technical solutions of the utility model, according to technical spirit pair of the present utility model Any modification or equivalent variations and modification that above example is made, still fall within the range of technical solutions of the utility model.
