Description

Distance-light integrated illumination system

Technical field

The utility model belongs to vehicle illumination field, and in particular to a kind of distance-light integrated illumination system.

Background technique

Headlamp is also headlight, is installed on the both sides of the head of the vehicles such as automobile, is used for night illumination.Due to The illuminating effect of headlamp directly affects the operation and traffic safety of driving at night, therefore countries in the world traffic management department Its lighting criteria is mostly defined with legal form.With the continuous development of technology, that incandescent vacuum lamp of past is successively washed in a pan It eliminates, the headlamp of present automobile is based on halogen lamp, xenon lamp.

The headlamp of the vehicles such as car headlamp has its unique light distribution structure, can also be divided according to luminous type For high beam and dipped headlight.Such as the light that high beam issues is shot forward straight after the reflection of lampshade reflector, it is " remote with formation Light ".The light that dipped headlight issues keeps off the top half to lampshade reflector to anti-dazzling screen, and the light reflected away is all unrestrained downward Directive ground, with formation " dipped beam ", to will not cause to dazzle the eyes to the driver of opposite car.

Headlamp has very strict requirements to the distribution of the illumination of dipped beam, by taking dipped headlight right lateral makes as an example, such as Figure 1A, figure Shown in 1B, according to some photometric standards, when low beam mode is presented in headlamp, on vertical light distribution screen, h-h ' line is below bright Area needs to reach certain light intensity, is dark space, vehicle driver's eyes position that B50L is 50 meters on opposing lane above the HH of left side It sets, it is desirable that be primary illumination zone below the HH of left side in 650cd hereinafter, the excessively high generation of light intensity is avoided to dazzle the eyes.15 ° of right side oblique line, or Broken line HH → HH1 → H1H2 → H2H4 top of the 45 ° of oblique lines of person to horizontal vertical away from 25cm steering horizontal is dark space, and lower section is Other high lighting area and key lighting area.High lighting area provides right side road illumination for driver by the right side and road sign shines It is bright, while the largest light intensity requirement of BR point is set again, it avoids the pedestrian close to vehicle from generating and dazzles the eyes caused traffic safety thing Therefore.

Certain brightness requirement is needed in the region Zone III above dead line simultaneously, as shown in Figure 1 C, it is ensured that vehicle There is enough brightness in front upper place, and the pedestrian and opposite vehicle driver of vehicle front know the presence of vehicle, therefore define P1+P2+P3 >=190cd, p4+P5+P6 >=375cd, P7 >=65cd, P8 >=125cd.It cannot make the pedestrian of vehicle front again simultaneously With opposite vehicle glare of driver, cause traffic story, therefore defines P1 to P8 each point maximum value no more than 625cd.

LED itself has the unexistent many advantages of other lighting sources, for example low-voltage, longevity as new type light source Life, small in size, light-weight, response is fast, radiationless, pollution-free and resistance to various mal-conditions, and LED light emission direction is unifaciality (conventional light source be all volume 360 °), the advantages that being more advantageous to the Collection utilization of light, improve light utilization efficiency.Therefore with LED is that light source production LED headlamp is also a new trend, but existing LED light flux is not high, must in order to improve luminous flux Electric current must be improved, causes calorific value big, heat dissipating mass is big, reduces the service life.LED low-beam light is using currently on the market, still LED light flux is insufficient, and in order to reach standard, the brightness that intermediate region is done is high, and left and right sides brightness is decreased obviously very much, causes to drive The person's of sailing vision width is narrow.HID headlamp brightness ratio LED headlamp simultaneously currently on the market is bright, and many auto vendors are unwilling Brightness requirement selection LED headlamp is reduced, unless LED headlamp can reach the brightness degree and power consumption of HID headlamp Lower than HID headlamp, be no more than 25W, therefore LED headlamp will substitute HID headlamp completely, it is necessary to from lamp brightness, power, Heat dissipation, LED total light flux and optical system are all optimized, and existing optical system is difficult to meet the requirements again.

As shown in Fig. 2, sun directional light light, after prism reflects, white light is reflected into red, orange, yellow, green, green, Lan He Purple, blue light deviation angle is bigger than yellow light, illustrates that the same medium refraction index of the short correspondence of wavelength is big.It is yellow using sodium for defining refractive index It is calculated based on optical wavelength, since the refractive index that the light of different wave length corresponds to same medium is different, the longer refractive index of wavelength Smaller, wavelength is shorter, and refractive index is bigger.White light LEDs are excited to be mixed into white light by blue light+fluorescent powder at present, mainly by blue light and Huang Light mixing, such as PC Refractive Index of Material: when 1.586, blue light wavelength 470um, refractive index 1.594, therefore use projection-type light System certainly exists excessive Lan Xianxiang.

In order to mitigate excessive Lan Xianxiang in row, a variety of methods are taken, such as: it is beaten on the input optical surface of collector lens Site, mobile collector lens are allowed to defocusing, and reduce the big light distribution etc. of incidence angle.As shown in figure 3, leading currently on the market The headlamp optical texture of stream is using projection type optical system, and LED light source is placed at 8001 focus F1 of ellipsoid structure, Light by ellipsoid 8001 reflection after converge to F2 at, in front of F2 placement collector lens 8003, make by F2 light again The light intensity that convergence makes central area meet laws and regulations prescribed requirement makes the light of projection by placing dead line baffle at F2 The dark space of cut-off wire shaped is formed above spot, thus meet the requirement of test point as defined in laws and regulations, but it is reflective far from LED The incident angle α 1 of the light of face reflection to collector lens 8003 is big, keeps the deviation angle of blue light big, thus the blue light of central area Shared ratio is big, makes can have serious excessive Lan Xianxiang at dead line, and excessive blue area domain is big, and color seriously exceeds method law In region as defined in advising.In order to mitigate excessive Lan Xianxiang, collector lens 8003, micro-shifting moves Hmm outward, and incident light extends to optically focused It is equally α 1 that lens 8003 ', which form incidence angle, but incidence point becomes remote with a distance from collector lens 8003 ', makes light down The blue light ratio of micro-shifting, central area is reduced, to mitigate the excessive Lan Xianxiang in center, but light can be made toward dark space above collector lens Offset causes "cut-off"line to become unintelligible.Another method is reflective by modification ellipsoid, the region for keeping incident angle α 1 big The light of reflective surface is up corrected, and makes 1 jiao of α to become smaller, to mitigate the excessive Lan Xianxiang in center, while by 8003 focus of collector lens Light decreases, and the light intensity of central area is caused to reduce.
