Description
Technical Field
The utility model relates to a car light lighting technology field, concretely relates to car light lighting device and car light of multi-functional sharing light emitting area.
Background
With the rapid development of the automotive industry, higher demands are made on lighting devices for motor vehicles, including: 1. the car lamp illumination with different functions, different illumination intensities and different light colors is completed in the same luminous area so as to achieve the dynamic conversion effect of the lighting effect and realize a light emitting surface which is basically uniform and homogeneous; 2. because of the diversity of the installation positions of the lighting equipment of the motor vehicle, the effect is required to be achieved in a smaller space with different shapes, so that the design requirement of a novel car lamp is met, the appearance of the model is not influenced, and the design flexibility of the lighting device of the vehicle is improved; 3. the lighting appliances for different lighting functions are provided with different monochromatic light sources to realize different lighting functions; 4. the automobile lighting device has the following optical functions: the white DRL or PL first function and the yellow turn signal lamp second function, and the third function of other colors of vehicle lamps.
The design of lighting fixtures for different lighting functions of existing motor vehicles requires to take into account the requirements of the positioning adjacent to each other, i.e. a considerable space needs to be designed in the lighting fixture for installing these lighting fixtures with different functions, which usually require the individual lighting fixtures to form a matrix arrangement.
However, the matrix arrangement of the individual lighting fixtures requires a large space, and thus the lighting fixtures must be designed to have a large installation size to satisfy two or more lighting functional requirements.
In the existing lighting lamp, each LED is independently arranged, for example, in the figures 1 and 1, because of the spatial arrangement of wiring of a circuit board and the like, the distance between the LEDs cannot be too close, and a gap of about 2mm is needed between the LEDs. Resulting in a need for a larger installation space.
2. Because two LEDs can not be arranged in the middle, if 1 LED is arranged in the middle, 1 LED is offset, the effect is that the light-emitting area can be irradiated more uniformly by the middle function, the whole light-emitting area can not be irradiated uniformly by the offset function, and the lighting effect is poor. If both are offset, both functions will be affected to some extent.
The utility model patent "Lightingdevice for a motor vehicle", made by germany hela lamp limited (HELLA KGAA hue & CO) (application number: EP20080163803 application date: 2008.09.05) provides a vehicle lamp lighting device with different functions, and the technical solution of claim 1 disclosed by the utility model comprises the following features:
"① corresponds to multiple sets of light sources for multiple light functions;
② light guide body coupled with multiple groups of light sources and having at least one common light emergent surface for multiple functions;
③ multiple groups of light sources share one carrier;
④ the first light source functions as a daytime running light and/or a position light and the second light source functions as a turn signal light;
⑤ white light LED (1a) and amber light LED (1b) are disposed on the light source carrier "
However, the technical solution of the patent has the following problems: (1) the lighting device for the car lamp can not lead in incident light rays of a plurality of groups of light sources from different directions, namely, any angles, which makes it difficult to make more flexible spatial arrangement when the optical and structural design of the car lamp is made, for example, the light sources can only be incident from the rear and emergent from the front due to the limitation of the optical principle, or the light guide body adopts the form of a light guide body tube, thereby making the interval of the LEDs inconvenient to adjust (when the arrangement is made in a common form, such as the arrangement of the LED light sources incident from the rear, the LED interval is generally larger due to the optical structure, but the LED interval is large, which causes poor lighting appearance; meanwhile, it is inconvenient for the lighting device to arrange various internal structures and effectively utilize space; (2) the optical layering sense is poor, and various different modeling schemes are difficult to meet; (3) the light guide body is difficult to be tightly attached to the modeling opening of the tail lamp, and modeling appearance is affected.
For another example, the german utility model patent DE 10043660 a1 discloses a lighting device for a motor vehicle, which uses a light source carrier for mounting various vehicle lighting fixtures and shares a lamp body, wherein LEDs including two lights of different colors are arranged in a light assembly matrix disposed behind a reflector or a scattering mirror.
For example, in the utility model publication "CN 106016127A", shanghai xiao car light limited, "a car light illumination device with different functions", two LED light sources with different light colors are disposed on one side of the thick-walled transparent light guide body, and finally, light is emitted through the common light emitting surface of the thick-walled transparent light guide body, thereby realizing two different functions; and the LED light sources are respectively and independently provided with different circuit boards and are configured on one side of the light guide body so as to lead incident light rays of the two LED light sources with different light colors into the thick-wall transparent light guide body from different directions.
US patent 8764257 relates to a vehicle lighting device comprising two light sources that perform two light functions, one of which may be white light that performs the function of a vehicle headlight, and the other of which may be yellow light that performs the function of a vehicle turn signal, and a main light guide that transmits the light of the two light sources to a light exit surface.
Claim 8 of the patent further discloses a technical solution of using a main light guiding body and two auxiliary light guiding bodies, wherein the main light guiding body has two auxiliary branches, so that the light from the two light sources enters the main light guiding body from the auxiliary branches, and in claim 10, the light guiding body structure is further defined as a Y-shaped structure, i.e. the main light guiding body and the auxiliary branches are integrally designed as a Y-shape, the light inlet is designed at the upper part of the Y, and the light outlet is designed as the foot part of the Y.
However, the above-described prior art solutions have the following problems to a different extent, respectively:
(1) the lighting appliances used for different lighting functions need to be provided with different monochromatic light sources to realize different lighting functions; (2) two sets of lighting equipment are assembled in the space of a vehicle lamp device, so that a larger space of the vehicle lamp device is needed for designing and installing the lighting appliances; (3) the lighting devices which are separately arranged are difficult to be uniformly distributed on the same light-emitting surface, so the design requirements of a novel car lamp cannot be met; (4) since the lighting fixtures for different lighting functions are to be arranged next to one another, a considerable space for the lamp lighting device must be provided in the lighting device for installing the lighting fixtures. For example, in the situation where the arrangement of each lighting device requires a large space, the overall structure of the lighting device needs to be lengthened to meet the requirements of different lighting functions; (5) since each lighting device is usually used as a single lamp light source, but the light emitting bodies of various novel vehicle lamp lighting devices have light emitting surfaces with different structures, shapes and light emitting positions, for example, the light emitting surfaces are often arranged in a matrix form, which often results in that a substantially uniform and homogeneous light emitting surface cannot be realized in the previous lighting device; (6) a third function including other colors of the lamp for a vehicle cannot be realized except for the first function of the DRL or PL having a white color and the second function of the turn signal lamp having a yellow color.
