Description
Technical field
The present invention relates to the vehicle front lighting driving lamp, specifically, be easy to regulate the vehicle front lighting driving lamp of the luminous luminous power of the LED module that comprises at least two headlamps of vehicle front assembling.
Background technology
LED is widely used in the multiple applications such as traffic signals and signal system.In future soon, LED can replace incandescent lamp gradually in the automobile application, and the several years, inherent general lighting application replaced incandescent lamp, Halogen lamp LED and fluorescent lamp.LED can effectively improve brightness of illumination.
But there are some problems in LED because of the restriction in the characteristics in work and manufacturing, and the slight variation of voltage also can make the LED electric current produce greatly variation, needs to control the LED electric current by LED driver.
Nowadays, assemble LED on the headlamp that automobile uses, control the electric current of LED by the resistance that is connected in LED, launch gradually with the research work that solves luminous power deviation between a plurality of headlamps.
Summary of the invention
The invention provides the vehicle front lighting driving lamp of the luminous luminous power of LED module that a kind of at least two headlamps that are easy to the assembling of vehicles the place ahead comprise.
Vehicle front lighting driving lamp of the present invention comprises: the first LED module, and (Flux Bin) is luminous with the first luminous power with the first flux bin; The second LED module, luminous with the second luminous power with described the first flux bin and another the second flux bin (Flux Bin); And the LED driver module, luminous with the 3rd luminous power at first and second LED module for detecting described first and second flux bin, input first and second electric current to described first and second LED module.
The advantage that the present invention has is:
The vehicle front lighting driving lamp that the present invention relates to is, the resistance value of first and second resistance that configures on first and second LED module that comprises based on headlamp, detect first and second flux bin (Flux Bin), along with first and second electric current corresponding with first and second flux bin inputted first and second LED module, luminous with constant optical power at first and second LED module, thus be easy to be adjusted in the luminous luminous power of a plurality of headlamps.
Description of drawings
Fig. 1 means the control structure figure of vehicle front lighting driving lamp of the present invention.
Embodiment
For the purpose, technical scheme and the advantage that make the embodiment of the present invention clearer, below in conjunction with the accompanying drawing in the embodiment of the present invention, technical scheme in the embodiment of the present invention is clearly and completely described, obviously, described embodiment is the present invention's part embodiment, rather than whole embodiment.Based on the embodiment in the present invention, those of ordinary skills belong to the scope of protection of the invention not making the every other embodiment that obtains under the creative work prerequisite.Same reference marks in specification refers to same member.
With reference to the accompanying drawings embodiment of the present invention vehicle front lighting driving lamp is described in detail.
Fig. 1 means the control structure figure of vehicle front lighting driving lamp of the present invention.With reference to Fig. 1, the headlamp drive unit 100 of automobile can comprise: the first LED module 110, and (Flux Bin) is luminous with the first luminous power with the first flux bin; The second LED module 120 is along with the second flux bin (Flux Bin) different from described the first flux bin is luminous with the second luminous power; And LED driver module 130, make first and second electric current I 1, I2 input first and second LED module 110,120, in order to detect first and second flux bin, at first and second LED module 110,120 luminous with the 3rd luminous power.
Here, first and second LED module 110,120 is assemblied in two headlamps (without diagram) that vehicle front installs at least, and perhaps a headlamp can assemble a LED module, but is not limited to this.
The present invention is assemblied in two headlamps one with the first LED module 110, and the second LED module 120 is assemblied in another in two headlamps and describes for example.In other words, the first LED module 110 comprises a LED(D1 at least), a LED(D1) with a LED(D1) series, parallel or connection in series-parallel mix the first resistance (R1) that is connected.And the second LED module 120 comprises the 2nd LED(D2 at least) and with the 2nd LED(D2) series, parallel or connection in series-parallel mix the second resistance (R2) that is connected.At this moment, a LED(D1) be luminous with the first luminous power, the 2nd LED(D2) be luminous with another second luminous power different from the first luminous power.
Here, first and second LED(D1, D2) be luminous with first and second mutually different luminous powers, but also can be luminous with same luminous power, if luminous with same luminous power, first and second resistance (R1, R2) can have same resistance value, and is not limited to this.At this moment, the first resistance (R1) have with the first luminous power luminous with a LED(D1) corresponding the first resistance value of the first flux bin (Flux Bin), the second resistance (R2) have with the second luminous power luminous with the 2nd LED(D2) corresponding the second resistance value of the second flux bin.
Here, described flux bin is, when making LED, for illustrating the LED operating characteristic causes of change with the variation generation of process, get the operating characteristic sample, to the similar group (Batch) in LED when classifying, what occur that the reason of the difference of luminous power is classified when inputting set electric current is exactly described flux bin.For example, for the LED that generates 20 to 30 lumen (lumen) flux, can distribute flux bin coding P in set electric current, distribute flux bin coding Q for the LED that generates 30 to 40 lumen flux in same electric current.At this moment, LED driver module 130 is that first and second resistance (R1, R2) series, parallel of comprising with first and second LED module 110,120 or connection in series-parallel mix and be connected and detect each described first and second resistance value of first and second resistance (R1, R2).In other words, LED driver module 130 is based on described first, second flux bin of described first, second resistance value detection of first and second resistance (R1, R2).At this moment, LED driver module 130 is for based on described first and second flux bin, at first and second LED module 110,120 luminous with the 3rd luminous power, can make first and second electric current I 1, I2 input first and second LED(D1, D2).Here, described the 3rd luminous power can be the low optical power in described first, second luminous power, and at first and second LED module 110,120 luminous, can control first and second electric current.
Described the 3rd luminous power can be the intermediate light power between described first and second luminous power, at first and second LED module 110,120 luminous, can control described first and second electric current.As mentioned above, LED driver module 130 can detect the flux bin of at least one LED by the resistance value that judgement is connected in the resistance of LED, thereby is easy to change the LED module that comprises LED, is beneficial to the luminous power deviation that reduces between a plurality of LED modules.
Above embodiment and particular terms only in order to technical scheme of the present invention to be described, are not intended to limit; Although with reference to previous embodiment, the present invention is had been described in detail, those of ordinary skill in the art is to be understood that: it still can be modified to the described technical scheme of aforementioned each embodiment, perhaps part technical characterictic wherein is equal to replacement; And these modifications or replacement do not make the essence of appropriate technical solution break away from the scope of the described technical scheme of various embodiments of the present invention.
