Fig. 2 is a top view of a lens and reflector according to an exemplary embodiment of the present disclosure. Fig. 3 is a side view of a lens and reflector according to an exemplary embodiment of the present disclosure. Fig. 4 is another perspective view of a lens and reflector according to an exemplary embodiment of the present disclosure. Fig. 5 is a schematic view of light passing through a lens and reflector according to an exemplary embodiment of the present disclosure.
As shown in fig. 1 to 5, the present disclosure provides a light emitting module 1, the light emitting module 1 including: a light source 10, the light source 10 for emitting light; a reflector 20 configured to reflect light rays from the light source 10; a lens 30 configured to project light rays after being reflected by the reflector 20; a heat sink 40 configured to dissipate heat from the light source 10 and to provide support and fixation for the light source 10, reflector 20, and lens 30.
The light emitting module of the embodiment can reduce the stacking of the lens and the light source, not only improves the design precision, but also simplifies the assembly process and reduces the assembly deviation.
As shown in fig. 1 to 5, the light source 10 and the reflector 20 may be disposed on the same surface of the heat sink 40. The light source 10 may be a semiconductor light source or a light emitting diode. The light emission color of the light source 10 may be selected according to actual needs. The light sources 10 may be provided in plural, and accordingly, the reflectors 20 may be provided in plural, in one-to-one correspondence with the respective light sources 10. The reflector 20 may have a reflective surface assigned to the respective light source 10, which may be a single continuous surface or a compound reflective surface having a plurality of sub-continuous surfaces. The lens 30 is arranged to receive and project light reflected by the reflective surface of the light source 10. In the present embodiment, the lens 30 is also provided as a plurality of portions accordingly, which respectively receive and project the light reflected by the reflecting surface of each light source 10. More light propagation modes can be realized.
In order to position and fix the lens 30 and the reflector 20, positioning holes and screw holes for the reflector 20 are provided on the heat sink 40, the positioning holes position the reflector 20 and the lens 30 relative to the heat sink 40, and fasteners may be screwed into the screw holes through the through holes of the reflector 20. This allows for a more stable and accurate assembly of the lens 30 and the reflector 20 on the heat sink 40.
As shown in fig. 1, the heat sink 40 may further be provided with a partition for disposing the light sources 10 of different functions on the heat sink 40, while avoiding interference of light emitted when the different light sources 10 are simultaneously operated.
In one embodiment of the present disclosure, the reflector 20 is made of a high temperature resistant PC material. The reflector made of the high-temperature-resistant PC material has strong firmness, is very impact-resistant, and has low forming shrinkage rate and good dimensional stability.
In one embodiment of the present disclosure, a reflective coating is applied to the reflector 20 to totally reflect light, thereby securing the light efficiency of the light emitting module 1. The reflective coating may be made of any suitable material, and the present utility model is not particularly limited.
In one embodiment of the present disclosure, lens 30 is preferably made of a transparent PC material. The lens made of the transparent PC material has high transparency and can better ensure the light emitting effect.
In one embodiment of the present disclosure, the reflector 20 and the lens 30 are molded as a unitary member. Therefore, the assembly process between the reflector 20 and the lens 30 can be omitted, the assembly process is simplified, errors caused by assembly are avoided, and the light-emitting precision is improved. Meanwhile, the structure of the light-emitting module 1 can be simplified, the overall size of the light-emitting module 1 is reduced, and a more compact and simplified structure is obtained.
In one embodiment of the present disclosure, the reflector 20 and the lens 30 are integrally formed by a two-shot molding process. Different materials are molded into a whole through a double-color injection molding process, so that stable connection between the reflector and the lens can be ensured, the boundary is clear, and the light emitting precision is improved while the assembly is reduced.
The light emitting module can reduce the stacking of the lens and the light source, not only improves the design precision, but also reduces the assembly deviation.
The disclosure also discloses a lighting device comprising the light emitting module 1.
In an embodiment of the present disclosure, the light emitting module 1 may be a lighting and/or signaling module. The light emitting module may generate: an illumination beam, such as a low beam, a high beam, etc.; signal beams, e.g., for direction indication, positioning, braking, etc.; or an illumination and indication beam.
Alternative embodiments will become apparent to those skilled in the art to which the present disclosure pertains without departing from its spirit and scope. The scope of the disclosure is, therefore, indicated by the appended claims rather than by the foregoing description and exemplary embodiments described therein.
