Description
Technical field
The invention belongs to photoelectric lighting technical field, relate to a kind of tunnel illumination taillight integrating LED illumination and sunlight optical fibre and throw light on.
Background technology
What be conventionally used to tunnel illumination has high-pressure mercury lamp, LED, one end fluorescent lamp etc., and these light fixtures are all under certain voltage, because high temperature makes gas ionization or electron transition, thus release energy, and excite electromagnetic wave, namely luminous.The principle of these lightings is all convert electrical energy into luminous energy at different conditions, and its electro-optical efficiency is only 10 ~ 30%, and remaining becomes various forms of heat, thus unavoidably causes the waste of energy.
With regard to sunlight optical fibre lighting engineering, be mainly limited to the research to sunlight optical fibre illuminator, because the application of current sun light lighting in tunnel is still in conceptual phase, and tunnel illumination is different from general architectural lighting, its special requirement is distributed with to the luminous intensity distribution of light fixture, therefore not yet has the research for the sunlight optical fibre illumination taillight of tunnel illumination and report at present.Although the patent of invention of the optical fiber lamp of the existing a kind of sunshine lighting of data display, this patent is provided with the convex lens that receives sunlight, lower end is provided with the concavees lens of radioluminescence light, the concentrating light principles of convex lens is just simply utilized to collect sunshine, what utilize concavees lens disperses principle outgoing sunshine, as tunnel is this, optical field distribution is not required that secondary distribution is carried out to emergent light in higher use region especially according to different places, also mean that the invention of this patent cannot make emergent light for tunnel illumination.
Summary of the invention
In view of this, the object of the present invention is to provide a kind of tunnel illumination taillight integrating LED illumination and sunlight optical fibre and throw light on, this tunnel illumination taillight is collected by sunlight optical fibre and is transmitted sunshine, by free-form surface lens sunshine shone again and need field of illumination, realize the peak use rate of sunshine; And sun light lighting technology and LED illumination technology are integrated in one, the seamless switching of sun light lighting and LED illumination under different weather can be realized, meet the tunnel illumination demand under different weather.
For achieving the above object, the invention provides following technical scheme:
Integrate the tunnel illumination taillight that LED illumination and sunlight optical fibre throw light on, this tunnel illumination taillight comprises lens, LED chip, light fitting panel, optical fiber, support; Described LED chip is fixed on light fitting panel, and described lens are fixed on light fitting panel, and described optical fiber is through light fitting panel and LED chip; The emergent light of optical fiber and the emergent light of LED chip distribute after lens; Described optical fiber is used for gathering and transmitting sunshine; Described support is used for fixing taillight; Described lens are used for carrying out secondary distribution to emergent light.
Further, described lens are free-form surface lens.
Further, the exiting surface of described optical fiber and LED chip are in same level.
Further, described tunnel illumination taillight also comprises thermal component, and thermal component is positioned on light fitting panel.
Further, described thermal component is positioned at front and/or the side of light fitting panel.
Beneficial effect of the present invention is: provided by the inventionly a kind ofly integrate the tunnel illumination taillight that LED illumination and sunlight optical fibre throw light on and include free-form surface lens for carrying out secondary distribution to emergent light, ensure no matter be from the sunshine of fiber exit or the light from LED outgoing, its optical field distribution all meets tunnel illumination demand, improves the utilization ratio of emergent light; And sun light lighting technology and LED illumination technology are integrated in one, the seamless switching of sun light lighting and LED illumination under different weather can be realized, meet the tunnel illumination demand under different weather.

Detailed description of the invention
Below in conjunction with accompanying drawing, the preferred embodiments of the present invention are described in detail.
A kind of tunnel illumination taillight integrating LED illumination and sunlight optical fibre and throw light on provided by the invention, as shown in Figure 1, this tunnel illumination taillight comprises lens 1, LED chip 2, light fitting panel 3, optical fiber 4, support 6 to concrete internal structure; Described LED chip is fixed on light fitting panel, and described lens are fixed on light fitting panel, and described optical fiber passes back through light fitting panel and LED chip from light fitting panel, and is fixed on light fitting panel; The emergent light of optical fiber and the emergent light of LED chip distribute after lens; Described optical fiber is used for gathering and transmitting sunshine; Described support is used for fixing taillight; Described lens are used for carrying out secondary distribution to emergent light.Described lens are free-form surface lens, require that design can meet the free-form surface lens of the optical field distribution demand of tunnel illumination according to tunnel illumination.The exiting surface of described optical fiber and LED chip are in same level.
Tunnel illumination taillight also comprises thermal component 5, and thermal component is positioned on light fitting panel, and thermal component can be positioned at front and/or the side of light fitting panel.
The sunshine collected is transferred to taillight by optical fiber, because the exiting surface of optical fiber passes light fitting panel and is positioned at free-form surface lens, thus making the sunshine of outgoing after lens, light beam carries out secondary distribution, makes the optical field distribution requirement meeting tunnel illumination from the sunshine of lens injection; When the outer sunshine of Tunnel is more weak, illumination of the present invention is switched to LED illumination pattern, equally, after free-form surface lens, the emergent light of LED is made also to meet the optical field distribution demand of tunnel illumination, the light of described tunnel illumination taillight injection tunnel road surface distribution as shown in Figure 2, this distribution meets the rectangle light distribution requirements of tunnel illumination.Fig. 3 is the structure of tunnel illumination taillight of the present invention, and the light path of tunnel illumination taillight emergent light of the present invention as shown in Figure 4.
What finally illustrate is, above preferred embodiment is only in order to illustrate technical scheme of the present invention and unrestricted, although by above preferred embodiment to invention has been detailed description, but those skilled in the art are to be understood that, various change can be made to it in the form and details, and not depart from claims of the present invention limited range.
