Description

A headlight illumination system capable of constantly projecting a light domain contour

The invention relates to a lamp illumination system, in particular to a lamp illumination system capable of constantly projecting a light domain profile.

In addition to the functions of the locomotive in the left and right turn, or the warning when braking, the main function is to provide lighting at night and to remind the car in all directions, thereby reducing the chance of accidents. In the case of general lighting, when the lighting function is provided, in order to avoid the phenomenon that the headlights are uncomfortable and glare to the incoming vehicle, the scope of illumination of the headlights (also called the light field), and the traffic cut-off regulations of the cut-off line in many countries are in many countries. Have their specifications. However, the size of the aforementioned optical domain or its contour does not change too much in the normal travel of the locomotive.

However, when a locomotive makes a turn, there is often a way for the knight to be called a "pressing car" (that is, the body and the locomotive faucet and the body are taken to a lower side and approach the ground), and the side is lower and closer. Distorted travel on the ground. This will cause the original light field to be extremely distorted, which will affect the lighting effect of the lights. At the same time, it will easily illuminate the opposite car, which will cause glare to the driver of the car and affect the overall driving safety.

Although there have been designers who have adopted a constant design pattern for such a light field, that is, the light of the lamp is projected onto a reflector lamp holder, the reflector lamp holder is transmitted through a tilt correction control unit, that is, using an inclination angle measurement. The utility model can be arranged on the locomotive for detecting the inclination angle of the locomotive to obtain a tilt angle data of the locomotive; and a driving mechanism, the driving mechanism is connected with the reflector lamp holder for driving the deflection lamp holder to form a deflection direction, And according to the tilt angle data of the locomotive, the reflector lamp holder is driven to be corrected with respect to the tilt angle of the locomotive. However, such a configuration using a reflector holder maintains a constant projection of the contour of the light field when illuminated. In addition to providing a reflector lamp holder in addition to increasing production costs, and the failure rate is relatively high, the components are relatively cumbersome. And because the light of the light group is reflected by the reflector base, Light is emitted in the form of "indirect projection". The rotation of the reflector base during the twisting process tends to shift the focal length, causing the loss of focus and distortion in the contour of the light domain.

In view of the deficiencies of the prior art, the present inventors have proposed a technical solution for solving the problem. For this purpose, a lighting system for a vehicle lamp set with a constant projection light field profile is designed for use in lighting of a locomotive, including: a pedestal comprising: a horizontal portion and an upright portion perpendicular to the horizontal portion; a vehicle light group: a space disposed between the horizontal portion of the pedestal and the upright portion; and the root of the vehicle light group is pivoted The erecting portion includes: a tilting angle measuring device, which is provided on the locomotive for detecting the tilt angle of the locomotive to obtain a locomotive tilt angle data; and a driving mechanism, the driving mechanism and the vehicle The lamp group forms a connection, and the driving mechanism signalsly connects the tilt angle data of the locomotive, and drives the lamp group to perform a ring correction with respect to the tilt angle of the locomotive according to the tilt angle data of the locomotive, so as to maintain the angle of the lamp group constant. So that the vehicle light group can constantly project the light domain contour when irradiated.

The present invention mainly adopts the above configuration, so that the light domain contour projected by the vehicle light group is fixed regardless of whether the vehicle is tilted left or right, thereby maintaining the overall better illumination effect, and avoiding excessive tilting of the locomotive. The light projected by the light group affects the driving safety of the incoming vehicle.

Compared with the prior art, the present invention maintains the configuration of the light group with constant projection of the light domain contour when the vehicle light group is irradiated, and does not need to additionally provide a reflector lamp holder, but directly emits the light source with the vehicle light group. In addition to reducing production costs, and the failure rate is relatively low, the components are relatively simple. And because the light of the light group is directly emitted through the light group, the light is emitted in a "direct projection" pattern, and the light field is relatively clear and vivid.
