Description
Technical field
The present invention relates to technical field of automotive electronics, particularly automobile lamp is specifically a kind of for automobile front
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 light bulb gradually
Diversified vehicle light shape structure now is gradually no longer applicable in, multi-chip LED light source is increasingly becoming headlight of new generation can not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 currently on the market, due to current LED encapsulation technologies and heat control
The limitation of technology processed is wanted 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 of a certain product, middle 1 chip output light flux 300lm of both sides or so, intermediate 5 chips
Output light flux 1500lm or so, total light flux 2100lm or so.The light-emitting surface size of one single chip is 1mm*1mm on 5 chips,
Chip chamber spacing is 0.1mm.The spacing in intermediate 5 chips and 1 chip light emitting face of both sides is 0.5~1mm, the light source of 1 chip of both sides
Center is 4.25mm with intermediate 5 chip light source center spacing.
In this way, traditional plurality of LEDs combined light source is exactly that first light source length is long the problem of bringing, with PES ellipsoid system points
It is disagreed to an image-forming principle, causes 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 which adaptation requires increasing vehicle light shape demand.
The content of the invention
The object of the present invention is 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 shape
Light source arrangement form causes light type bad, and solves that, since 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 scheme of the invention is：A kind of LED light source for automobile front, the LED light
Source is made of plurality of LEDs arrangement, and the plurality of LEDs is single-chip LED, and the more 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, the LED light source according to the present invention for automobile front, single-chip LED arrangements
Into " ten " font.
Further, the LED light source according to the present invention for automobile front, single-chip LED arrangements
Into " L " shape.
Further, the LED light source according to the present invention for automobile front, single-chip LED arrangements
Into linear type.
Further, the LED light source according to the present invention for automobile front, single-chip LED arrangements
Into " river " font.
Further, the LED light source according to the present invention for automobile front, single-chip LED arrangements
Rectangularity, square or triangle.
Further, the LED light source according to the present invention for automobile front, the LED light source is by 7 lists
Chip LED arrangement combination is formed.
Further, the LED light source according to the present invention for automobile front, two single-chip LED's shines
Interplanar distance is less than 0.15mm.
The present invention also provides a kind of automobile front, including LED light source described in any one of the above embodiments.
The advantageous effect that the present invention reaches：Single LED of the present invention shines interplanar distance smaller, and light source is more concentrated, optical
It can be more preferable.And spread geometry is various, is adapted to various vehicle light shapes, and applicability is wider.
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 surfaces scale diagrams；
Fig. 4-Fig. 6 is the embodiment of LED light source arrangement mode of the present invention.
Specific embodiment
The present invention is described in further detail 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 forms, and the 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 linear type LED light source, compared to conventional junction shown in FIG. 1
Structure, the LED light source of the present embodiment is in the case of light-emitting surface size constancy, and spacing between two LED light-emitting surfaces is from original 1mm
Reduce 0.15mm till now, light source total length L=7.9mm, only there are one chip in present invention list LED, luminous flux exists
300lm or so, spacing smaller, light source are more concentrated, and optical property is more preferable.And due to the diminution of dimension of light source, entire PES modules
Size integrally reduce, be more advantageous to vehicle light shape.
PES speculums are changed by the later stage, can be accomplished using 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 is adapted to various vehicle light shapes.It 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 next-generation small chip light source of high power is equally applicable, and light-emitting surface size is 0.7mm*0.7mm, and light-emitting area is
0.5mm2.The size of next-generation single-chip can reduce 30%, simultaneously because the diminution of dimension of light source, the size of entire PES 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
It makes choice.
