Description
Technical field
It is specifically a kind of for automobile front the present invention relates to technical field of automotive electronics, particularly automobile lamp
LED light source and automobile front.
Background technology
In automobile lamp, LED light source is applied more and more, with the development of automobile market, is put forth effort on safe and easypro
The car light field of suitable driving experience has increasingly shown for the headlight demand of high brightness.When high power discharge bulb gradually
Diversified vehicle light shape structure now is gradually no longer applicable, multi-chip LED light source is increasingly becoming headlight of new generation can not
Or scarce power-assisted pushing hands.
Most commonly used multi-chip LED is single 5 chips in the market, due to current LED encapsulation technologies and heat control
The limitation of technology processed, want to break through single 5 chips difficult.In order to further improve the input luminous flux of light source, to obtain more
High output light flux, the multiple light courcess system of plurality of LEDs occur.This light source often using combination form, by plurality of LEDs with
One determining deviation is lined up, as shown in Figure 1.
Fig. 1 is the LED light source wiring board, the middle chip output light flux 300lm of both sides 1 or so of a certain product, middle 5 chips
Output light flux 1500lm or so, total light flux 2100lm or so.The light-emitting area size of one single chip is 1mm*1mm on 5 chips,
Chip chamber spacing is 0.1mm.The spacing in middle 5 chips and the chip light emitting face of both sides 1 is 0.5~1mm, the light source of the chip of both sides 1
Center is 4.25mm with middle 5 chip light source center spacing.
In this way, traditional plurality of LEDs combined light source is exactly the problem of bringing, the first light source length length, with PES ellipsoid system points
Disagreed to an image-forming principle, cause light type bad, LED utilization ratios more in the outer part are lower.Second, due to multi-chip LED
Presence, light source LED array arrangement mode is single, and simple single or double arrangement can not fully meet needs.3rd, light source
Size is big, causes PES module sizes big, it is difficult to adapts to require the vehicle light shape demand increasingly improved.
The content of the invention
It is an object of the invention to provide a kind of LED light source for automobile front, LED light source of the invention uses more
Single-chip LED arrangements are combined into various shapes, existing to solve the needs of to meet luminous flux and different vehicle light shapes
Light source arrangement form causes light type bad, and solves that, because dimension of light source is big, vehicle light shape can not be met, simultaneously because single
Arrangement mode, the problem of vehicle light shape demand can not be fully met.
To achieve the above object, the solution of the present invention is：A kind of LED light source for automobile front, described LED light
Source is made up of plurality of LEDs arrangement, and described plurality of LEDs is single-chip LED, and more described single-chip LED combinations are arranged into
Various shapes, the quantity and arrangement shape of the single-chip LED are determined according to the luminous flux of vehicle light shape structure and actual demand
It is fixed.
Further, according to the LED light source of the present invention for automobile front, more described single-chip LED
It is arranged into " ten " font.
Further, according to the LED light source of the present invention for automobile front, more described single-chip LED
It is arranged into " L " shape.
Further, according to the LED light source of the present invention for automobile front, more described single-chip LED
It is arranged into " one " font.
Further, according to the LED light source of the present invention for automobile front, more described single-chip LED
It is arranged into " river " font.
Further, according to the LED light source of the present invention for automobile front, more described single-chip LED
Arrangement rectangularity, square or triangle.
Further, according to the LED light source of the present invention for automobile front, described two single-chip LED
Light-emitting area be smaller than 0.15mm.
The present invention also provides a kind of automobile front, including the LED light source described in any of the above-described.
The beneficial effect that the present invention reaches：Single LEDs of the present invention light, and interplanar distance is smaller, and light source is more concentrated, optical
Can be more preferable.And spread geometry is various, various vehicle light shapes are adapted to, applicability is wider.
Brief description of the drawings
Fig. 1 is traditional LED light source arrangement form；
Fig. 2 is existing one arrangement form embodiment of LED light source；
Fig. 3 is existing LED light-emitting areas scale diagrams；
Fig. 4-Fig. 6 is the embodiment of LED light source arrangement mode of the present invention.
Embodiment
The present invention is further detailed explanation with specific embodiment below in conjunction with the accompanying drawings.
The LED light source of the present invention combines arrangement by plurality of LEDs and formed, and described plurality of LEDs is single-chip LED, described
More single-chip LED combinations be arranged into various shapes, the quantity and arrangement shape of the single-chip LED is according to vehicle light shape knot
Structure and the luminous flux of actual demand determine.
Embodiment：
Below by taking 7 single-chip LED as an example, the LED light source of the present invention is illustrated.
7 single-chip LED shown in Fig. 2 and Fig. 3 are arranged in " one " font LED light source, compared to the conventional junction shown in Fig. 1
Structure, the LED light source of the present embodiment is in the case of light-emitting area size constancy, and spacing between two LEDs light-emitting areas is from original 1mm
Reduce 0.15mm till now, light source total length L=7.9mm, an only chip, luminous flux exists on the single LEDs of the present invention
300lm or so, spacing is smaller, and light source is more concentrated, and optical property is more preferable.And due to the diminution of dimension of light source, whole PES modules
Size integrally reduce, be more beneficial for vehicle light shape.
PES speculums are changed by the later stage, can accomplish to use same reflection mirror, the light source light type base of different number of chips
This is consistent, the only difference of road surface irradiating width, and meet 4 chip 500lm luminous fluxes simultaneously, 5 chip 600lm luminous fluxes, 6 chips
750lm, 7 chip 900lm luminous fluxes.
The shape of LED combination arrangement can change according to vehicle light shape, and as shown in Figure 4, Figure 5 and Figure 6, LED is various
Spread pattern, it is adapted to various vehicle light shapes.In other embodiments, can be according to actual vehicle light shape, by more singles
Piece LED is arranged in other shapes, such as rectangle, square or triangle etc..
The small chip light source of high power of future generation is equally applicable, and light-emitting area size is 0.7mm*0.7mm, and light-emitting area is
0.5mm2.The size of single-chip of future generation can reduce 30%, simultaneously because the diminution of dimension of light source, whole PES size is whole
Body can also reduce 30%, and possibility is provided for smaller size of PES modules.It is expected that lens can accomplish 25*40.
The LED quantity and spread pattern of the present invention are one embodiment that the present invention selects, and can not limit this hair
Bright protection domain, the spread geometry of quantity and LED light source for single-chip LED, can be according to luminous flux and vehicle light shape
Selected.
