The invention discloses a projection-type LED automotive high-beam lamp, which is characterized in that it includes 4 high-power LEDs, each LED is made of a single chip; it has four reflection planes, and each LED corresponds to a different reflection plane. The central light output direction of the LED is perpendicular to the corresponding reflection plane. The first reflection plane and the second reflection plane are symmetrical based on the reference axis of the lamp. Both the first reflection plane and the second reflection plane form a δ angle with the reference axis of the lamp. The δ angle is 75 ~86°, the third reflection plane and the fourth reflection plane are symmetrical based on the reference axis of the lamp, and both the third reflection plane and the fourth reflection plane form an angle β with the reference axis of the lamp, and the β angle is 77°～87°. The present invention has the advantages of light concentration, small projection angle and long distance. It can replace the traditional car high beam.
Description
Technical field
The present invention relates to light fixture, be specifically related to projection type LED automobile high beam.
Background technology
Present normally used automobile front is mainly thought the master with hernia lamp, Halogen lamp LED, and the market sales volume is bigger.The hernia auto lamp is compared with the light fixture of other type with the halogen auto lamp, exist to need specialty to start problems such as power supply, serviceable life be short.The LED luminescence efficiency of carrying out suitability for industrialized production has at present reached 100 lumens/watt, along with its luminous brightness efficient of continuous advancement in technology also can bigger again improve, the colour temperature variation range of LED is big in addition, and promptly the LED colour temperature is controlled easily, LED has that operating voltage is low, power consumption is little, and volume is little.
Summary of the invention
The objective of the invention is to overcome the deficiencies in the prior art part, provide to have the projection type LED automobile high beam that LED launches indirectly, many focuses converge.
The technical solution used in the present invention is:
Projection type LED automobile high beam is characterized in that comprising 4 great power LEDs, and every LEDs is that single-chip is made; Have four planes of reflection, the respectively corresponding plane of reflection of every LEDs, the plane of reflection that the center light direction that every LEDs sends is corresponding with it is vertical, first plane of reflection and second plane of reflection are based on light fixture datum axis symmetry, first plane of reflection, second plane of reflection all become the δ angle with the light fixture datum axis, the δ angle is 75～86 °, the 3rd plane of reflection, the 4th plane of reflection are based on light fixture datum axis symmetry, the 3rd plane of reflection, the 4th plane of reflection all become the β angle with the light fixture datum axis, and the β angle is 77～87 ° of angles.
Further, the respectively corresponding para-curve reflector of every LEDs, four overlapped places of reflector are cut off, and after the light that LED sends reflected through reflector, the directional light that levels off to throwed away.
Further, the size conforms parabolic function of reflector relation, and the light fixture projection light is 50 meters distant places, and hot spot is of a size of the circular light spot less than 50m.
Further, every LEDs power is at 7～10W, and luminescence efficiency is greater than 75lm/W, the light fixture general power between 28～40W, total light flux 2800～4000 lm.
Compared with prior art, the present invention has following beneficial effect:
1, adopt 4 great power LEDs, every LEDs is that single-chip is made, and has concentrated little, the distance of crevice projection angle that helps of light.
2, in four planes of reflection, the center light direction that each light source sends is vertical with the plane of reflection, can reach the hot spot effect that four led light sources converge at certain distance through suitably adjusting the plane of reflection and datum axis angulation δ, β.
3, corresponding para-curve reflector of every LEDs light source, four overlapped places of reflector are cut off, and after the light that LED sends reflected through reflector, the light that sends and the differential seat angle of datum axis were smaller, the directional light that levels off to throws away, and projection distance is far away.Effect with alternative orthodox car lamp.
Description of drawings

Fig. 2, left view of the present invention.
Fig. 3, front elevation of the present invention.
In Fig. 1～Fig. 3,1 is first plane of reflection, and 2 is second planes of reflection, 3 is the 3rd planes of reflection, and 4 is the 4th planes of reflection, the 5th, and reflector, the 6th, reflector, the 7th, reflector, the 8th, reflector, the 9th, LED, 10 is datum axis of the 3rd plane of reflection, the 11st, and the datum axis of light fixture, 12 is datum axis of the 4th plane of reflection, 13 is datum axis of first plane of reflection, and 14 is datum axis of second plane of reflection.
Embodiment
As shown in Figure 1 to Figure 3, design LED auto lamp structure, shape according to the design hot spot, hot spot forms distance, the shape and the size of design reflector, determine four planes of reflection and angulation light fixture datum axis 11 more respectively, design four planes of reflection, each plane of reflection and light fixture datum axis have a certain degree, first plane of reflection 1, second plane of reflection 2 is based on light fixture datum axis 11 symmetries, and with 11 one-tenth δ angles of light fixture datum axis, 75～86 ° of δ angular ranges, the 3rd plane of reflection 3, the 4th plane of reflection 4 is based on light fixture datum axis 11 symmetries, and with 11 one-tenth β angles of light fixture datum axis, 77～87 ° of β angular ranges utilize machine die software design product, carry out the die sinking design, form structure at last, select and install four great power LEDs again, every LEDs power is at 7～10W, and luminescence efficiency is greater than 75lm/W, the light fixture general power between 28～40W, total light flux 2800～4000 lm.
