Abstract
The invention discloses reflective and refractive LED automobile lamps, which comprises four large-power LEDs (Light-Emitting Diode) and four parabolic reflection cups. The light emergence diameter of each LED is less than 10mm; each LED is positioned at the vertex of the parabola of one parabolic reflection cup, and a focus part of each parabolic reflection cup is provided with a ray refractive cone; and the rays emitted by the LED are reflected by the ray refractive cone and projected to the parabolic reflection cup, and reflected out by the parabolic reflection cup. In the invention, by adopting the LED lamps with direct and indirect reflection and multi-focus point convergence, the reflective and refractive LED automobile lamps have a means of reflective rays and have a function of refractive rays, have rays which are emitted by the lamps and ejected in parallel, and reduces the glare difficulty of the LED lamps to the maximum extent. The radiation of automobile lamps to eyes is reduced so as to enable the centre point of the light source to be a diameter range of the lamps to avoid the excessive focus of LED rays.
Description
Technical field
The present invention relates to light fixture, be specifically related to reflection and refractive LED automobile lamps.
Background technology
The volume of production and marketing of automobile is in continuous expansion, and only just there is the number more than 1,000 ten thousand every year in China.Along with the output increasing of automobile, its relevant accessory industry also increases thereupon, and auto lamp is one of main accessory, and the auto lamp accessory is mainly based on hernia auto lamp and halogen auto lamp at present.The LED luminous efficiency has reached 100 lumens/watt, the efficient with the orthodox car lamp is identical, but LED development of technology, higher luminous efficiency might be arranged, replacing the orthodox car lamp may, particularly the colour temperature adjustable range of LED is big, helps using, and it has, and operating voltage is low, power consumption is little.Traditional hernia lamp, Halogen lamp LED exist needs specialty to start technical problems such as power supply, service life be short.
Summary of the invention
The objective of the invention is to overcome above-mentioned the deficiencies in the prior art part, provide have LED directly, indirect reference, many focuses reflection and the refractive LED automobile lamps that converge.
The technical solution used in the present invention is:
Reflection and refractive LED automobile lamps comprise four great power LEDs and four parabola shaped reflectors, and the bright dipping diameter of every LEDs is less than 10mm; Every LEDs is positioned at the place, parabola summit of a parabola shaped reflector, is equipped with the light refraction cone at the focus place of each parabola shaped reflector; The light that LED sends projects parabola shaped reflector after the refraction of light refraction cone, reflected away by parabola shaped reflector again.
Further, four LEDs just in time are positioned on foursquare four summits.
Further, four overlapped places of parabola shaped reflector are cut off.
Further, every LEDs power is at 7～10W, and luminous efficiency is greater than 75lm/W.
Compared with prior art, the present invention has following advantage:
1, the bright dipping diameter of every LEDs is less than 10mm, to guarantee that light can carry out light refraction well.
2, LED is positioned at the place, parabolical summit of parabola shaped reflector, and the light refraction cone is positioned at the focus place of parabola shaped reflector.Parabola shaped reflector has the parallel projection of light that focus is sent goes out, and the effect that reflector has parallel rays that projects is promptly arranged.
3, the distance range according to 15～50 meters of auto lamp dipped headlights light designs reflector, the size conforms parabolic function relation of reflector, and the light refraction cone is installed at the focus place, and LED is installed at place, parabola summit.
4, every LEDs power is at 7～10W, and luminous efficiency is greater than 75lm/W, the about 35W of light fixture general power, the about 3200lm of total light flux.
5, the present invention be adopt LED directly, the light fixture that converges of indirect reference, many focuses, existing reflection ray mode, refraction type light function is arranged again, has the parallel ejaculation of light that light fixture sends, at utmost reduced the dazzle difficult problem of LED light fixture, auto lamp has reduced the radiation of human eye, makes the central point of light source be the diameter range of light fixture, avoids LED light too concentrated.

The specific embodiment
According to the parabola shaped reflector of the structural design among Fig. 1 to Fig. 9, the light refraction cone, adopt 4 great power LEDs, the bright dipping diameter of every LEDs is less than diameter 10mm, adopt four LED light emitting source refraction groups, every group light refraction mode is identical, led light source is positioned at the place, parabolical summit of parabola shaped reflector, the light refraction cone is positioned at the focus place of parabola shaped reflector, the parallel projection of light that parabola shaped reflector can send focus is gone out, the effect that reflector has parallel rays that projects is promptly arranged, according to the distance range of 15～50 meters of auto lamp dipped headlights light, the size conforms parabolic function of reflector relation, the light refraction cone is installed at the focus place, LED is installed at place, parabola summit, and every LEDs power is at 7 ~ 10W, and luminous efficiency is greater than 75lm/W, the about 35W of light fixture general power, the about 3200lm of total light flux.
