Source device uniformly light-emitting, without apparent bright dark space point.But due to the unique light distribution requirements of car light, need " cross " light intensity point
Cloth, for such LED car lamp in later period light distribution meeting relative difficulty, optical design is complex.
Summary of the invention
In order to solve problem above, the object of the present invention is achieved like this: a kind of light suitable for automobile LED headlight
Source, which is characterized in that including conducting wire and LED chip, the conducting wire links multiple LED chip groups by way of serial or parallel connection
At the different LED component of four groups of light type.
Further, the LED component one uses four identical LED chips, wherein LED chip 1 and 2 phase of LED chip
It is mutually in parallel, while connecting with LED chip 3, the formation of LED chip 4, effect obtained is: LED chip 1 is obtained with LED chip 2
The electric current obtained halves, and LED chip 3 and 4 chip of LED chip work normally, while the chip array sequence of LED component is " 1342
", so, there is apparent difference in light source center light intensity and edge light intensity, have reached light distribution requirements required for us.
Further, the LED component is second is that by LED chip 1, LED chip 2, LED chip 3, LED chip 4, LED core
Piece 5, LED chip 6 or more LED chip are constituted using concatenated mode, and simultaneous selection is arranged more than both sides in light source center
Chip, making LED car lamp, central light strength is higher at work.
Further, in LED component three LED chip 1, LED chip 2, LED chip 3 or LED chip 4 all by individually electricity
Road control, can the independent electrical parameter for adjusting each chips, in this way can be light by driving circuit when we use
Realize " both sides are dark, it is intermediate it is bright " light distribution.
Further, in device four described in LED LED chip 1 and 2 chip size of LED chip than LED chip 3 and LED chip
4 is small, and wherein LED chip 1 and 2 chip of LED chip are parallel with one another, while connecting with LED chip 3, the formation of LED chip 4, is obtained
Effect be: LED chip 1 halves with the electric current obtained of LED chip 2, and LED chip 3 and LED chip 4 work normally, simultaneously
The chip array sequence of LED component is " 1342 ", and so, there have been apparent poor with edge light intensity for light source center light intensity
It is different, reach light distribution requirements required for us.
Further, the LED component carries out photoelectric parameter to LED chip using the circuit structure of serial or parallel connection
Control, while the size of each chip size can make variation with demand.
The invention has the following advantages:
(1) LED car lamp can be made to shine more to assemble, the light type after finished product installation is more concentrated；
It (2) is not in lighting dark space；
(3) irradiation distance greatly increases, and eliminates bad light type bring Exploration on Train Operation Safety；
(4) LED component can replace LED size as needed, and number of chips facilitates later period light distribution without limitation.
Detailed description of the invention
The present invention will be further explained below with reference to the attached drawings and specific examples.
Fig. 1 is the array light source of existing LED car lamp (left side is circuit diagram, and the right side is the array of figure of LED component).
Fig. 2 is array light source of the invention (left side is circuit diagram, and the right side is the array of figure of LED component)
One is LED component one in Fig. 2, and two be LED component two, and three be LED component three, and four be LED component four.
Specific embodiment
In order to make the technical means, creative features, achievement of purpose and effectiveness of the invention easy to understand, below with reference to tool
Invention is further described in body embodiment.
Referring to Fig. 2, present embodiment uses following technical scheme: a kind of light source suitable for automobile LED headlight, institute
State conducting wire (not marking) and link LED chip 1(1 by way of serial or parallel connection), LED chip 2(2), LED chip 3(3), LED
