According to one general technical concept of the present disclosure, as shown in fig. 1, there is provided a light emitting device 10 for a vehicle, including: a first light emitting module 100 and a second light emitting module 200, wherein the first light emitting module 100 comprises a first light source 101 and a first reflector 102, the first reflector 102 is configured to receive and reflect light emitted by the first light source 101 to form a first light beam, the second light emitting module 200 comprises a second light source 201 and a second reflector 202, the second reflector 202 is configured to receive and reflect light emitted by the second light source 201 to form a second light beam; the second light emitting module 200 further comprises a third light source 203, the third light source 203 being configured to emit light, which is received and reflected via the second reflector 202 to form a third light beam.
In one embodiment, the second light emitting module further comprises a lens 205, said lens 205 being configured to project light reflected by said second reflector 201.
In an embodiment, the third light source 203 is for being activated when the first light emitting module 100 of the light emitting device 10 is in operation. The third light source 203 preferably has a low power for illuminating the corresponding projection lens 205 of the second light emitting module 200 when the first light emitting module 100 is operated, thereby ensuring a uniform and constant illumination appearance of the light emitting device 10.
According to an embodiment of the utility model, the first light source 101 and the second light source 201 are used for generating a first light beam and a second light beam, respectively. The arrangement of the third light source 203 does not affect the functions performed by the first light source 101 and the second light source 201.
In one example, the first light source 101 is configured to implement a low beam function and the second light source 201 is configured to implement a high beam function.
In one example, the lighting apparatus 10 further comprises a controller configured to control the third light source 203 to be illuminated when the first light source 101 is illuminated, to illuminate the lens 205 of the second light module 200 when the low beam function. In other words, the third light source 203 is configured to be turned on simultaneously with the first light source 101 in the first light emitting module 100 to illuminate the second light emitting module 200, i.e., the projection lens 205 corresponding to the high beam function, in the low beam mode.
In one example, the second reflector 201 includes a first reflective surface that collects and reflects light rays emitted by the second light source 201, and a second reflective surface that collects and reflects light rays emitted by the third light source 203, and the lens 205 is configured to project light rays reflected by the reflector 202 to form the second light beam and the third light beam, respectively.
Specifically, the second light source 201 is disposed at a focal point of the reflective surface of the second reflector 202 of the second light emitting module 200 such that the second light beam has the maximum intensity.
In one example, to ensure that the third light source 203 is capable of illuminating the lens 205 of the second light emitting module 200 when the first light source 101 is in the operational mode, the third light source 203 is arranged in the vicinity of the second light source 201.
Preferably, the third light source 203 should avoid the focal point setting of the second reflector 202 of the second optical module 200 to avoid that in low beam mode the third light beam generated by the third light source 203 causes glare to traffic participants. In one example, the distance between the third light source 203 and the second light source 201 is greater than 1mm. Of course, the distance between the third light source 203 and the second light source 201 may be selected and adjusted according to actual needs, and the present utility model is not limited in particular.
In one example, the second reflector 202 includes a second reflective surface that collects and reflects light rays emitted by the third light source 203, and the lens 205 is configured to project light rays from the third light source 203 reflected by the second reflector 202 and form the third light beam. The lens 205 projects the second light beam formed by the second light source 201 and the third light beam formed by the third light source 203, so that the lens 205 corresponding to the second light emitting module 200 can be effectively lightened when the first light emitting module 100 works, and a satisfactory lighting effect can be generated. As shown in fig. 3, wherein the broken line represents the optical path of the light from the second light source 201, and the solid line represents the optical path of the light from the third light source 203.
In one example, the second reflecting surface that collects and reflects the light emitted by the third light source 203 is the same surface as the first reflecting surface that collects and reflects the light emitted by the second light source 201. The third light source 203 and the second light source 201 can make the lens 205 of the second light emitting module 200 light together with the first light emitting module 100 to generate a satisfactory illumination effect under the condition that the structure of the second light emitting module 200 is not changed, so that the lens corresponding to the high beam can be lightened under the low beam mode.
In order to secure the lighting effect, the third light source 203 is preferably arranged close to the second light source 201. In one example, the distance between the second light source 201 and the third light source 203 may be set to 5-15mm to achieve a better lighting effect.
In an exemplary embodiment, as shown in fig. 3, the second light emitting module 200 further includes a printed circuit board 207, and the second light source 201 and the third light source 203 are disposed on the printed circuit board 207. As an example, the second light source 201 and the third light source 203 are arranged on the same printed circuit board, so that the structure of the optical module is more compact and the manufacturing cost is reduced. Arranging the second light source 201 and the second light source 203 on the same printed circuit board may enable the second light source 201 and the third light source 203 to dissipate heat via the same heat sink 208, further reducing the size of the light emitting device. However, it will be appreciated by those skilled in the art that in other embodiments of the present disclosure, the second light source 201 and the third light source 203 may also be disposed on different printed circuit boards, respectively.
In an exemplary embodiment, as shown in fig. 4, the second light source 201 and the third light source 203 are disposed in the same package structure to further simplify the structure of the printed circuit board and reduce the processing steps of the printed circuit board, thereby reducing the cost.
As an example, the first, second and third light sources 101, 201 and 203 may each include a Light Emitting Diode (LED). The LED has the advantages of small size, low power consumption and high luminous intensity. By adopting the LED light source, the structure of the optical module can be more compact.
According to the light-emitting device, the second optical module of the light-emitting device is additionally provided with the light source, so that the lens corresponding to the high beam function can be lightened in the low beam mode, interference to the low beam function is avoided, and other structures of the light-emitting device are not required to be changed. According to the light-emitting device disclosed by the utility model, the structure is simple, the ideal lighting effect can be realized at lower cost, and the lighting appearance in the low-beam mode is effectively improved.
According to another aspect of the present disclosure, there is also provided a headlamp for a motor vehicle, the headlamp being a light emitting device as described above.
According to yet another aspect of the present disclosure, there is also provided a motor vehicle having the headlamp as described above.
The headlight for a motor vehicle and the motor vehicle according to the utility model have at least the advantages of the aforementioned lighting device.
Those skilled in the art will appreciate that the embodiments described above are exemplary and that modifications may be made by those skilled in the art, and that the structures described in the various embodiments may be freely combined without conflict in terms of structure or principle.
Although the present utility model has been described with reference to the accompanying drawings, the examples disclosed in the drawings are intended to illustrate preferred embodiments of the utility model and are not to be construed as limiting the utility model.
Although a few embodiments of the present disclosed concept have been shown and described, it would be appreciated by those skilled in the art that changes may be made in these embodiments without departing from the principles and spirit of the general inventive concept, the scope of which is defined in the claims and their equivalents.
It should be noted that the word "comprising" does not exclude other elements or steps, and that the word "a" or "an" does not exclude a plurality. In addition, any element numbers of the claims should not be construed as limiting the scope of the utility model.
