In other instances, well-known structures and devices are shown in block diagram form in order to simplify the drawing.
Fig. 1 shows an optical module of a headlamp for a vehicle in the related art. As shown in fig. 1, the optical module includes a single light source 1', a condenser 3', a mirror 5', and a lens. The light source 1' is used to emit light. The condenser 3' is located on the downstream side of the light source 1' and is configured to condense the light emitted from the light source 1 '. The reflecting mirror 5' is located on the downstream side of the condenser 3' and is configured to reflect the light condensed by the condenser 3' in the main light-emitting direction. The lenses include an inner lens 7 'and an outer lens 8', both located on the downstream side of the mirror 5', and configured to project light rays reflected by the mirror 5'. The light source 1' and its associated optical components are mainly used to implement the high beam function of the headlamp, whereas the daytime running light function or position light function of the headlamp is usually implemented by adjusting the flux of the light source 1, whereas, in order to implement the daytime running light function or position light function, the current required to supply the light source 1 must be very low, for example less than 50mA (this value is less than about 1% of the flux for the high beam function).
According to one general technical concept of the present disclosure, there is provided an optical module for a head lamp of a vehicle, including: a first light source for a first light function; a first condenser located on a downstream side of the first light source and configured to condense light emitted from the first light source; a first reflecting mirror located on a downstream side of the first condenser and configured to reflect the light condensed by the first condenser in a main light exit direction; a second light source for a second light function; a second condenser located on a downstream side of the second light source and configured to condense light emitted by the second light source; a second reflector located on a downstream side of the second condenser and configured to reflect the light condensed by the second condenser in the main light-exit direction; and a lens configured to project light rays of the first and second light sources that are reflected by the respective reflectors.
Fig. 2 illustrates an optical module of a head lamp for a vehicle according to an exemplary embodiment of the present disclosure. As shown in fig. 2, the optical module includes a first light source 1 for a first light function, a first condenser 3, a first reflector 5, and a lens. The first light source 1 is for emitting light. The first condenser 3 is located on the downstream side of the first light source 1, and is configured to condense light emitted from the first light source 1. The first reflecting mirror 5 is located on the downstream side of the first condenser 3, and is configured to reflect the light condensed by the first condenser 3 in the principal light-outgoing direction. The lens includes an inner lens 7 and an outer lens 8, both of which are located on the downstream side of the first reflecting mirror 5 and are configured to project the light reflected by the first reflecting mirror 5. The optical module further comprises a second light source 2 for a second light function, a second light concentrator 4 and a second mirror 6. The second light source 1 is for emitting light. The second condenser 4 is located on the downstream side of the second light source 2, and is configured to condense light emitted from the second light source 2. The second reflector 6 is located on the downstream side of the second condenser 4, and is configured to reflect the light condensed by the second condenser 4 in the main light-exit direction. The inner lens 7 and the outer lens 8 are both located on the downstream side of the second reflector 6 and are configured to project the light reflected by the second reflector 6. Compared to the optical module in the prior art (as shown in fig. 1), the optical module provided by the present disclosure implements the second light function by adding another light source and the optical components (e.g., the second condenser 4 and the second reflector 6) associated with the light source, so as to avoid implementing two different light functions by adjusting the current of the same light source. The optical module according to the present disclosure can realize different light functions through the same illumination window, and simultaneously independently control the different light functions.
As an example, the first and second light sources 1 and 2 may each include a Light Emitting Diode (LED). The LED has the advantages of small volume, low power consumption and high luminous intensity. By adopting the LED light source, the structure of the optical module can be more compact.
In one exemplary embodiment, the first light function is a high beam function and the second light function includes one or more of a daytime running light function, a position light function, and the like. In an embodiment of the invention, the first light source 1 and the second light source 2 are used to achieve different functions. Thus, they can be switched on and off, respectively, as required.
In an exemplary embodiment, the optical module further includes a printed circuit board (not shown) on which the first and second light sources 1 and 2 are disposed to be powered by the printed circuit board. As an example, the first light source 1 and the second light source 2 are disposed on the same printed circuit board, so that the structure of the optical module is more compact and the manufacturing cost is reduced. However, it will be understood by those skilled in the art that in other embodiments of the present disclosure, the first light source 1 and the second light source may be disposed on different printed circuit boards, respectively.
In an exemplary embodiment, the second light source 2 is arranged within a circular range centered on the first light source 1. Of course, the second light source 2 may also be arranged at other positions, for example within a rectangular range centered on the first light source 1.
In an exemplary embodiment, the first condenser 3 has a reflective curved surface protruding away from the first light source 1 to condense light from the first light source 1. Similarly, the second condenser 4 has a reflective curved surface protruding away from the second light source 2 to condense light from the second light source 2. In this exemplary embodiment, the first condenser 3 and the second condenser 4 take the form of curved mirrors, however, it will be appreciated by those skilled in the art that in other embodiments of the disclosure, the first condenser 3 and/or the second condenser 4 may also take the form of a condensing bowl.
In an exemplary embodiment, the first concentrator 3 and the second concentrator 4 are integral, so that the optical module is more compact and easier to install. It should be noted that, in some other embodiments of the present disclosure, the first condenser 3 and the second condenser 4 may also be separate components, in which case, the first condenser 3 and the second condenser 4 may be fixed by respective fixing members.
In an exemplary embodiment, the first mirror 5 and the second mirror 6 are integral, so that the optical module is more compact in structure and easy to mount. Which may for example have a parabolic, hyperbolic, elliptical or more complex known curved shape. Of course, it may be formed of a smooth curved surface or may be formed by splicing a plurality of strip-shaped reflecting elements. It should be noted that in some other embodiments of the present disclosure, as shown in fig. 3, the first reflector 5 and the second reflector 6 may be separate components, for example, the first reflector 5 is mounted on a mounting frame, the second reflector 6 is mounted on another mounting frame, or the first reflector 5 and the second reflector 6 may be mounted on a common mounting frame.
According to another aspect of the present disclosure, there is also provided a headlamp for a motor vehicle, the headlamp comprising a housing and an optical module as described above, the optical module being located within the housing.
According to yet another aspect of the present disclosure, there is also provided a motor vehicle having a headlamp as described above.
According to the optical module, the headlamp for the vehicle and the vehicle of the present disclosure, by additionally providing a light source and an associated optical component in the optical module, the light source is used for realizing the light function different from the main light function realized by the existing light source, so that two different light functions can be easily realized through the same lighting window, and the realization of two different light functions by adjusting the current of the same light source is avoided.
It will be appreciated by those skilled in the art that the embodiments described above are exemplary and can be modified by those skilled in the art, and that the structures described in the various embodiments can be freely combined without conflict in structure or principle.
Although the present invention has been described in connection with the accompanying drawings, the embodiments disclosed in the drawings are intended to exemplify preferred embodiments of the present invention, and should not be construed as limiting the present invention.
Although a few embodiments of the present general inventive 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.
