Description

FIELD OF THE INVENTION

The invention generally relates to the field of vehicle lighting, and particularly to a lighting module for a vehicle headlamp.

BACKGROUND OF THE INVENTION

Reflective type lighting device has been widely used in vehicle (such as automotive) lighting field, especially vehicle front-lighting field. A conventional reflective type lighting device for a low beam mode typically comprises a light source, a reflector and a shutter, such as a black shield. The shutter is used to block a part of light emitted from the light source to avoid glare to drivers of oncoming vehicles, such that the generated low beam is more comfortable and safer to those drivers. However, the use of shutter results in light loss of the light source, thereby reducing the utilization efficiency of the light source. In addition, a separate surface structure usually needs to be designed on the reflector to generate a zone III beam, i.e., a part of the low beam located mainly above the bright/dark boundary, which is necessary for the low beam, which surface structure occupies a part of the physical space of the reflector. Such separate surface structure complicates the reflector and may deteriorate the optical performance of the reflector for the low beam outside of zone III.
Therefore, there is a need to an improved lighting device for the vehicle headlamp which can both avoid glare and generate the zone III beam of the low beam with diminished or even without the above-mentioned disadvantages.

SUMMARY OF THE INVENTION

A general objective of the embodiments of the present invention is to provide a lighting module for a vehicle headlamp which does not require a separate surface structure on the reflector and does not require a shutter while being capable of avoiding glare and generating a zone III beam of a low beam, so as to eliminate or at least mitigate the above-mentioned problems.
According to the present invention, there is provided a lighting module for a vehicle headlamp comprising a first light source, a first optics, and a second optics spaced apart from the first optics. The first optics is configured to receive and redirect a first part of light from the first light source to create a main part of a low beam in front of the vehicle, and the second optics is configured to receive and redirect a second part of light from the first light source to create a zone III beam of the low beam in front of the vehicle.
In the above proposed lighting module, the second optics can be used to replace the conventional shutter to receive and redirect the second part of light from the first light source, which would otherwise be blocked by the shutter, to create the zone III beam of the low beam in front of the vehicle, such that the shutter and the separate surface structure on the reflector can be omitted, thereby eliminating the glare and increasing the utilization efficiency of light from the first light source, improving the low beam performance and simplifying the module.
The term "zone III beam" used herein is a common term in the art, which refers to a wide beam that is essential for the low beam according to UN ECE R112 Low Beam Regulation. For example, when a vehicle is driving on a road without street lights in low beam mode at night, if there is no zone III beam of the low beam, it is difficult for the driver of the vehicle to see obstacles such as branches of tree or signs over the road in front of the vehicle, which is prone to traffic accidents. With the zone III beam of the low beam, the obstacles over the road can be illuminated so as to avoid potential dangers.
The first light source herein may be any suitable light source, including but not limited to a light emitting diode (LED). The first light source is used to generate a low beam with a bright/dark cut-off line as projected onto the road in front of the vehicle, and the main part of the low beam and the zone III beam of the low beam together constitute the eventual low beam. The main part of the low beam is mainly below the bright/dark cut-off line, and the zone III beam of the low beam is mainly above the bright/dark cut-off line.
The meaning of the term "redirect" used herein includes but is not limited to reflection, refraction, deflection, transmission, which depends on the specific types of the first and second optics.
In an embodiment, the first optics may comprise a reflector with a first focal point. The reflector may be a parabolic reflector or any other suitable reflector. The first light source is arranged at the first focal point of the reflector. The second optics could be selected from a group consisting of a lens and a light guide. In a case where the second optics is a lens with a second focal point, the second focal point of the second optics coincides with the first focal point of the first optics. In this way, the first light source coincides with the first focal point of the first optics and the second focal point of the second optics, which facilitates the projection of light redirected by the first and second optics to infinity, such as onto the road in front of the vehicle, to form the low beam.
Alternatively, the second optics may be a light guide with a light incident surface and a light exit surface. A distance between the first light source and the light incident surface of the light guide is configured such that the second part of light from the first light source enters the light guide via its light incident surface and exits the light guide via its light exit surface to create the zone III beam of the low beam in front of the vehicle. Preferably, the distance between the first light source and the light incident surface of the light guide is in a range of 0 mm to 3 mm, such that most of the second part of light from the first light source may enter the light guide.
It should be noted that there are no specific limitations for the material of the second optics, as long as the second optics is designed such that the second part of light redirected by the second optics is capable of creating the zone III beam of the low beam in front of the vehicle.
In an embodiment, the lighting module for the vehicle headlamp may further comprise a substrate. The substrate may be a printed circuit board for powering the first light source. The first light source, the first optics and the second optics are attached to a same surface of the substrate, such that the first light source is between the first optics and the second optics. Optionally, the second optics may be screwed or glued to the substrate. In this way, the substrate provides both support for the first light source, the first optics and the second optics and power for the first light source, which enables a compact system.
As an alternative for creating the low beam, the lighting module for the vehicle headlamp of the present invention may further comprise a third optics positioned at an optically downstream location for the first and second optics. The third optics has a focal plane between the second optics and the third optics. In this case, the first optics is configured to receive and redirect the first part of light from the first light source to a first area on the focal plane, and the second optics is configured to receive and redirect the second part of light from the first light source to a second area on the focal plane. The third optics is configured to receive and redirect light from the first area on the focal plane to create the main part of low beam in front of the vehicle and light from the second area on the focal plane to create the zone III beam of the low beam in front of the vehicle. Optionally, the third optics may be a projection lens with a third focal point.
In another embodiment of the present invention, the lighting module for the vehicle headlamp may further comprise a second light source and a fourth optics to generate a high beam. Specifically, the fourth optics is configured to receive and redirect a third part of light from the second light source to create a main part of a high beam in front of the vehicle, and the second optics is configured to receive and redirect a fourth part of light from the second light source to create a concentrated beam of the high beam in front of the vehicle.
For the proposed lighting module for the vehicle headlamp of the present invention, the second optics may also be used in the high beam mode, to create a concentrated beam so as to optimize values of some test points for the high beam.
The general operation process of the lighting module for the vehicle headlamp in the embodiments of the present invention may be described as follows: when the vehicle is driving in the low beam mode, the first light source is turned on and the second light source is turned off, the first light source, the first optics and the second optics cooperate with each other to create the low beam with the zone III beam; when the vehicle is driving in the high beam mode, the first light source is turned off and the second light source is turned on, the second light source, the fourth optics and the second optics cooperate with each other to create the high beam with the concentrated beam.
The first and second light sources in some embodiments may be separate light sources, and in some embodiments may be two sub-light sources of one light source. The first and second light sources may be same or different, which is not limited herein. The first optics and the fourth optics are designed such that they do not interfere with each other optically, that is, light emitted from the first light source in the low beam mode illuminates only onto the first optics without onto the fourth optics, and light emitted from the second light source in the high beam mode illuminates only onto the fourth optics without onto the first optics. Optionally, there is a shield between the first optics and the fourth optics to further avoid potential optical crosstalk.
In an embodiment, the fourth optics may comprise a reflector with a fourth focal point, and the second optics may be a lens with a second focal point which coincides with the fourth focal point of the reflector. The second light source may coincide with the fourth focal point of the fourth optics and the second focal point of the second optics, which facilitates the projection of light redirected by the second and fourth optics to infinity, such as onto the road in front of the vehicle, to form the high beam.
The third optics mentioned above can also be used in the high beam mode to create the high beam. In this case, the fourth optics is configured to receive and redirect the third part of light from the second light source to a third area on the focal plane, and the second optics is configured to receive and redirect the fourth part of light from the second light source to a fourth area on the focal plane. The third optics is configured to receive and redirect light from the third area on the focal plane to create the main part of the high beam in front of the vehicle and light from the fourth area on the focal plane to create the concentrated beam of the high beam in front of the vehicle.
The position of the concentrated beam relative to the main part of the high beam is not strictly limited herein. For example, the concentrated beam may be near the center of the main part of the high beam, so as to increase the distance illuminated by the high beam. Alternatively, the concentrated beam may be near the edge of the main part of the high beam, so as to widen the range illuminated by the high beam.
It will be appreciated by those skilled in the art that two or more of the above disclosed embodiments, implementations and/or aspects of the present invention may be combined in any way deemed useful. Different modifications and variations of the lighting module for a vehicle headlamp can be carried out by a person skilled in the art based on the disclosure of the present invention.

DETAILED DESCRIPTION OF EMBODIMENTS

While the present invention is susceptible of embodiments in many different forms, only some specific embodiments are shown in the drawings and will be described in detail herein, with the understanding that the description is to be considered as explanation of the basic principle of the invention and not intended to limit the invention only to the specific embodiments shown and described herein.
It should be noted that various components in different figures are not drawn to scale. Besides, relative positional relationships between individual elements shown in the figures are only used to illustrate the basic principles of the invention and should not be considered to limit the scope of the invention.
Fig. 1 illustrates a lighting module 100 for a vehicle headlamp when operated in a low beam mode. The lighting module 100 comprises a first light source 101, a first optics 102, and a second optics 103 spaced apart from the first optics 102. The first light source 101 may be any suitable light source, such as an LED, which is not limited herein. As shown in Fig. 1, light emitted by the first light source 101 can be considered to be divided into two parts, i.e., a first part and a second part. The first part of light emitted from the first light source 101 is incident onto the first optics 102, which then redirects the light incident thereon towards infinity, such as towards a road in front of the vehicle, to form a main part of the low beam. The second part of light emitted from the first light source 101 is incident onto the second optics 103, which then redirects the light incident thereon also towards infinity, such as towards the road in front of the vehicle, to form a zone III beam of the low beam. The main part of the low beam and the zone III beam of the low beam together constitute the eventual low beam as projected onto the road in front of the vehicle. Figs. 5 (a) and (b) respectively illustrate a simulation diagram for only a zone III beam pattern and a simulation diagram for a low beam pattern comprising the zone III beam pattern and the main part of the low beam generated by the lighting module 100. As shown in Fig. 5 (b), the low beam pattern comprises a bright/dark cut-off line (L), the zone III beam pattern is a wide beam pattern and mainly above the bright/dark cut-off line (L), and the main part of the low beam is mainly below the bright/dark cut-off line (L). As compared to a low beam pattern without the zone III beam as shown in Fig. 5 (c), the low beam pattern as shown in Fig. 5 (b) may further improve the safety of driving.
Returning back to Fig. 1, the lighting module 100 further comprises a substrate 104. The first light source 101, the first optics 102 and the second optics 103 are attached to a same surface of the substrate 104, and the first light source 101 is between the first optics 102 and the second optics 103. Optionally, the second optics 103 may be screwed or glued to the substrate 104. In some embodiments, the substrate 104 is a printed circuit board for powering the first light source 101.
With the lighting module 100 for the vehicle headlamp, the second optics 103 replaces the conventional shutter for eliminating glare (such as a black shield) and hence reuses those light, that would otherwise be blocked by the shutter, to create the zone III beam of the low beam. In this way, the glare is eliminated and the utilization efficiency of the first light source 101 is improved with the second optics 103. In addition, as compared to a conventional lighting module in the prior art comprising a separate surface structure of a reflector for generating the zone III beam, the lighting module 100 provided herein improves the low beam performance and simplifies the system.
Figs. 2-4 are variations of the lighting module 100 as shown in Fig. 1, where the same reference numerals are used to indicate the same components as in the lighting module 100 of Fig. 1. In general, the lighting modules as shown in Figs. 2-4 also comprise the first light source 101, the first optics 102, the second optics 103, and the substrate 104. The lighting modules will be described in detail below with reference to Figs. 2-4.
Fig. 2 illustrates a lighting module 200 for a vehicle headlamp when operated in a low beam mode. In the lighting module 200, the first optics 102 is a reflector and the second optics 103 is a lens.
The first optics 102 is a parabolic reflector with a curved reflecting surface and with a first focal point F1. The parabolic reflector can be understood as a reflector whose reflecting surface is formed by revolutions of a parabola. The first optics 102 receives and reflects the first part of light from the first light source 101 to create the main part of the low beam in front of the vehicle. The parabolic reflector has the optical characteristics that when a light source, preferably a point light source is disposed at its focal point, most of light emitted by the light source will exit towards infinity parallel to the main axis of the reflector after being reflected by the reflector; or, when the light emitted by a light source parallel to the main axis of the reflector is projected onto the reflecting surface of the reflector, most of light will focus on its focal point after being reflected by the reflector. It should be noted that the parabolic reflector is only a specific example of the first optics 102, the present invention does not limit the specific forms of the first optics 102, as long as it is capable of generating the main part of the low beam in front of the vehicle.
The second optics 103 is a lens with a second focal point F2 which coincides with the first focal point F1 of the first optics 102. The second optics 103 receives and refracts the second part of light from the first light source 101 to create the zone III beam of the low beam in front of the vehicle. The second optics 103 has similar characteristics as the first optics 102 described above, that is, light rays parallel to the optical axis of the second optics 103 will be concentrated at the second focal point F2 of the second optics 103 after being refracted by the second optics 103; or, light rays emitted from the second focal point F2 of the second optics 103 will exit parallel to the optical axis of the second optics 103 after being refracted by the second optics 103.
The first light source 101 coincides with the first focal point F1 of the first optics 102 and the second focal point F2 of the second optics 103. With such an arrangement, the first part of light from the first light source 101 substantially becomes parallel light rays after being reflected by the first optics 102, and the second part of light from the first light source 101 also substantially becomes parallel light rays after being refracted by the second optics 103. As is known, parallel light rays have a small divergence angle, which facilitates the projection of light redirected by the first and second optics to infinity, such as onto the road in front of the vehicle, to form the low beam.
Fig. 3 illustrates a lighting module 300 for a vehicle headlamp when operated in a low beam mode. In the lighting module 300, the first optics 102 is a reflector and the second optics 103 is a light guide.
Like the lighting module 200 as shown in Fig. 2, the first optics 102 in Fig. 3 is a reflector with the first focal point F1, ant the first light source 101 is positioned at the first focal point F1 of the first optics 102.
The second optics 103 is a light guide with a light incident surface and a light exit surface. The second part of light from the first light source 101 enters the light guide via its light incident surface and then is deflected (such as totally reflected) in the interior of the light guide along its length direction, and finally exits the light guide via its light exit surface to create the zone III beam of the low beam in front of the vehicle. A distance D between the first light source 101 and the light incident surface of the light guide is designed to enable most of the second part of light from the first light source 101 to enter the light guide via its light incident surface. In a preferable example, the distance D between the first light source 101 and the light incident surface of the light guide is in a range of 0 mm to 3 mm, realizing a higher utilization efficiency of light from the first light source 101.
Fig. 4 illustrates an alternative for a lighting module for creating the low beam comprising the zone III beam.
An additional component, e.g. a third optics 105, is further included in the lighting module 400 of Fig. 4. The third optics 105 is positioned at an optically downstream location for the first optics 102 and the second optics 103. In this example, the third optics 105 is a projection lens with a focal plane P3 and a third focal point F3 thereon, and the focal plane P3 is between the second optics 103 and the third optics 105. The operation principle of the lighting module 400 is described in detail below with reference to Fig. 4.
The first optics 102 receives the first part of light from the first light source 101 and redirects it towards a first area S1 (shown with a dotted ellipse) on the focal plane P3. The second optics 103 receives the second part of light from the first light source 101 and redirects it towards a second area S2 (shown with a dotted ellipse) which is below the first area S1 on the focal plane P3. In this way, the first part and the second part of light coming originally from the first light source 101 are incident onto two different sections of the third optics 105, such as an upper section of the third optics 105 corresponding to the first part of light and a lower section of the third optics 105 corresponding to the second part of light. With the further redirection of the third optics 105, the first part of light originally from the first light source 101 will be projected below the bright/dark cut-off line (L) to form the main part of the low beam, and the second part of light originally from the first light source 101 will be projected above the bright/dark cut-off line (L) to form the zone III beam of the low beam.
In the lighting module 400, the first optics 102 optionally may be a reflector with a first focal point F1 and the first light source 101 may be arranged at the first focal point F1 of the reflector. The second optics 103 may be any suitable optics such as a lens or a light guide. With the third optics 105, the lighting module 400 provides more design freedom.
The above embodiments describe the lighting modules which are operated in the low beam mode. However, the lighting modules may also be used in a high beam mode, which will be described in detail below with reference to Figs. 6-8. For the sake of clarity, in the lighting modules shown in Figs. 6 and 7, the first light source 101 and the first optics 102 have been omitted, but this should never be considered as a limitation to the present invention.
As shown in Fig. 6, the lighting module 500 further comprises a fourth optics 106 and a second light source 107. The second light source 107 is used to generate a high beam and may be different from or same as the first light source 101. Specifically, when a vehicle comprising the lighting module 500 is driving in the high beam mode, the second light source 107 is turned on and the first light source 101 is turned off, and the fourth optics 106 receives a third part of light from the second light source 107 and redirects it towards infinity, to create a main part of the high beam in front of the vehicle. Meanwhile, the second optics 103 receives a fourth part of light from the second light source 107 and redirects it towards infinity, to create a concentrated beam of the high beam in front of the vehicle. The main part of the high beam and the concentrated beam of the high beam together constitute the eventual high beam as projected onto the road in front of the vehicle. The simulation diagrams for a concentrated beam and the eventual high beam comprising the concentrated beam and the main part of the high beam can be referred to Figs. 8 (a) and (b), respectively. It should be noted that the relative positional relationship of the concentrated beam and the main part of the high beam as shown in Fig. 8 (b) is only an example, which should not be considered as a limitation to the present invention. For example, the concentrated beam may be near the edge of the main part of the high beam.
Returning back to Fig. 6, the fourth optics 106 may be a reflector with a fourth focal point F4 which is similar to the first optics 102 as shown in Fig. 2, and the second optics 103 may be the same as that shown in Fig. 2. In such a case, the second light source 107 coincides with the fourth focal point F4 of the fourth optics 106 and the second focal point F2 of the second optics 103. Alternatively, the second optics 103 may also be a light guide as shown in Fig. 3. For specific details, reference may be made to the embodiments described in connection with Figs. 2 and 3, and they are not repeated herein for the sake of brevity.
As can be seen, the second optics 103 may also be used in the high beam mode to create a concentrated beam, thereby improving the luminous intensity or illumination range of the high beam as projected onto the road in front of the vehicle.
Fig. 7 illustrates an alternative for a lighting module for creating the high beam comprising the concentrated beam. As shown, the third optics 105 as mentioned above can also be used in the lighting module 600. Specifically, when the lighting module 600 is operated in the high beam mode, the fourth optics 106 receives and redirects the third part of light from the second light source 107 to a third area S3 (shown with a dotted ellipse) on the focal plane P3, and meanwhile the second optics 103 receives and redirects the fourth part of light from the second light source 107 to a fourth area S4 (shown with a dotted ellipse) which is below the third area S3 on the focal plane F3. The third optics 105 receives light from the third area S3 and light from the fourth area S4 on the focal plane P3 and then respectively redirects them towards infinity, such as towards the road in front of the vehicle, to create the main part of the high beam and the concentrated beam of the high beam, respectively.
As seen, a low beam system comprising the first light source 101 and the first optics 102 as well as a high beam system comprising the second light source 107 and the fourth optics 106 may share the second optics 103 (and optionally the third optics 105), to create the low beam or the high beam as desired.
It is important to note that light rays shown in the figures, only represent part, but not all, of the light rays within the whole lighting module. In fact, the light rays shown in all the figures are only used as representative examples for the purpose of illustrating the basic principle of the present invention, and clearly should not be read as exhaustive examples of all the light rays within the entire lighting module.
It should also be noted that the above-mentioned embodiments illustrate rather than limit the present invention, and that the person of ordinary skill in the art will be able to design many alternative embodiments without departing from the scope and spirit of the present invention. The scope of the present invention is limited only by the accompanying claims.
Furthermore, in the claims, any reference signs placed between parentheses shall not be construed as limiting the claims. Use of the verb "comprise" and its conjugations does not exclude the presence of elements or steps other than those stated in a claim. The article "a" or "an" preceding an element does not exclude the presence of a plurality of such elements. Also, references to first, second etc. are merely to be considered as labels and do not imply or describe any ordering, sequence, relation or properties of the features prefixed by these terms. The mere fact that certain measures are recited in mutually different dependent claims does not indicate that a combination of these measures cannot be used to advantage.
