![]() Dip-light headlamp
专利摘要:
The invention relates to the field of lighting engineering, in particular to automobile headlights designed to form a passing beam, and allows to improve the light distribution of the headlamp and manufacturability. The dipped-beam headlamp contains a light source with a cylindrical filament body, a diffuser and a reflector containing six sectors, the shape of which forms a smooth surface and provides the required light distribution. 1 hp f-ly, 5 ill. 公开号:SU1542425A3 申请号:SU874202647 申请日:1987-05-25 公开日:1990-02-07 发明作者:Брюн Норберт 申请人:Сиби Прожектер (Фирма); IPC主号:
专利说明:
The invention was related to lighting engineering, namely to car headlights designed to form a passing beam. The aim of the invention is to improve the phase light distribution and processability. FIG. 1 shows a passing beam headlamp, vertical section; in FIG. 2 - the same, rear view; on fig.Z-5 - traces of the reflected images of a body of heat on the screen, normalized to 25 meters. The dipped-beam headlamp contains a lamp with a cylindrical body 1, a canal, a reflector 2, and a diffuser 3. Reflector 2 consists of two paraboloid sectors 4 and 5, whose foci are located on both sides of the center of the incandescent body 1. Sectors 4 and 5 are bounded by the horizontal plane XOY and the plane forming an angle o with the horizontal equal to the elevation angle of the cut-off beam of the dipped beam. Sectors 4 and 5 are connected by additional reflective surfaces 6-9. Surfaces 6 and 7 are determined by the equation Y2 .Z2 SU) with 4fh 4f h (4fhfv + Y) Where n Y IYI and f. . ifr 1+ f + if Surfaces 8 and 9 are determined by the equation (Y cosol + Z sinoQ l -, - ,. t 4fhg (Z cosc6-Y sinfrL) T4fhC4fh fy + (Y sinfrQ JI 4fЈ + (Y sin) 2- f f Y соsoL + Z sin06 r "e n JY coso6 + Z sinoil and W 2 sino6 Tz cosoirY siricil Ј, (i + z with sol-Y sinaЈ rO + 2 4 h | Z cosoi-Y sinoi I where fe is the distance from the top of sectors 4 and 5 to the center of the filament body; n - constant in the range (1, + oo); . 1 - half the length of the Dakal body. Sectors 4 and .5 and surfaces 6–9 form a generally smooth reflector. The headlamp works as follows. Paraboloid sectors 4 and 5 The placement of images P under the cut-off line NS (Fig. L Surfaces 6 and 7 (Fig. 4)) mainly defines the horizontal cut-off line h (H. Surfaces 8 and 9 define the inclined NS line of the right part of the beam (Fig. 5).
