Description

[Technical Field]

[0001] The present invention relates to an automobile component, and more particularly to a multi-light source lighting module and an automobile lamp including the multi-light source lighting module. [Background technology]

[0002] Compared with incandescent lamps, light-emitting diodes have the advantages of small volume, high brightness, long service life, and power saving. When light-emitting diodes are applied to vehicle headlight clusters, they can generate high-brightness white light, which can reliably achieve lighting effects under normal circumstances. However, the white light generated by LED vehicle headlight clusters has a high color temperature, and in bad weather, the desired lighting effects are often not achieved. For example, in rainy, snowy, or foggy weather, this can further affect visibility while driving, which in turn affects driving safety.

[0003] Therefore, in bad weather, users often have to turn on fog lights to enhance driving safety, combining them with the white light of LED headlight clusters. However, because fog lights are installed low and have a short illumination distance, they usually only have a warning effect and do not provide good lighting. In addition, most fog lights are installed separately and are not even included as standard equipment when a car is sold. Furthermore, adding them separately increases the installation cost. Summary of the Invention [Problem to be solved by the invention]

[0004] In order to overcome the shortcomings of conventional LED vehicle headlight groups, the present invention further proposes installing a multi-color light source within the lighting module of the vehicle lamp, enabling different colored lights to be emitted simultaneously, thereby significantly improving the problem of conventional LED vehicle headlight groups having poor lighting effects in bad weather. [Means for solving the problem]

[0005] To achieve the above object, the present invention provides a multi-light-source lighting module, which includes at least one first optical adjusting element, at least one first light source for generating a first color light and projecting the first color light onto the first optical adjusting element, the first optical adjusting element for projecting the first color light forward of the multi-light-source lighting module, at least one second optical adjusting element, and at least one second light source for generating a second color light and projecting the second color light onto the second optical adjusting element, the second optical adjusting element for projecting the second color light forward of the multi-light-source lighting module, where the first color light and the second color light partially or completely overlap each other.

[0006] The present invention further provides an automotive lighting system including a plurality of the above multi-light source lighting modules integrated into the same socket.

[0007] In at least one embodiment of the present invention, the first optical adjusting member and the second optical adjusting member are reflector cups or lenses.

[0011] In at least one embodiment of the present invention, the first optical adjusting member is a reflector cup and the second optical adjusting member is a lens.

[0012] In at least one embodiment of the present invention, the multi-light-source lighting module further includes a third optical adjusting member connected to the second optical adjusting member. The third optical adjusting member is disposed on the optical path of the first color light, so that the first color light reflected by the first optical adjusting member is projected onto the third optical adjusting member, and the first color light is projected forward of the multi-light-source lighting module via the third optical adjusting member.

[0013] In at least one embodiment of the present invention, the first optical adjusting member and the second optical adjusting member are each a lens, and the first optical adjusting member and the second optical adjusting member are arranged with a gap between them.

[0014] In at least one embodiment of the present invention, the first color light is white light and the second color light is yellow light.

[0015] In at least one embodiment of the present invention, the first light source and the second light source are combined to form a color-changeable light-emitting module, and the projection ranges of the first color light and the second color light overlap.

[0016] In at least one embodiment of the present invention, the multi-light source lighting module further includes a control circuit and a switch. The control circuit is used to control the on / off of the first light source and the second light source. The switch is used to transmit a trigger signal to the control circuit. When the first light source is on, the control circuit turns on or off the second light source by receiving a specific number of trigger signals as one cycle.

[0017] In at least one embodiment of the present invention, when the control circuit receives a trigger signal a specific number of times while the first light source is on, it turns on the second light source based on that cycle and keeps the first light source on.

[0018] In at least one embodiment of the present invention, the control circuit includes a first driver and a second driver, the first driver being used to supply power to the first light source, and the second driver being used to supply power to the second light source.

[0019] In at least one embodiment of the present invention, when the control circuit receives a specific number of trigger signals while the first light source is off, it turns on the second light source based on the cycle, or when the control circuit receives a specific number of trigger signals while the first light source is on, it turns on the second light source based on the cycle and turns off the first light source.

[0020] In at least one embodiment of the present invention, the control circuit includes a driver and a switch, wherein the driver is used to supply power to the switch and output power to the first light source or the second light source via the switch.

[0021] In at least one embodiment of the present invention, the first light source and the second light source are each a light emitting diode.

[0022] In at least one embodiment of the invention, the automotive lighting system further comprises at least one auxiliary lighting module integrated into the socket. [Effects of the Invention]

In other words, the headlight cluster of the present invention can be quickly and easily installed on a general vehicle, improving the safety of the vehicle when driving.

DETAILED DESCRIPTION OF THE INVENTION

[0025] FIG. 1 shows a schematic structural diagram of an embodiment of an automotive lamp equipped with a multi-light source lighting module according to the present invention. The automotive lamp 1 includes at least one multi-light source lighting module 100. The multi-light source lighting module 100 is mounted in a socket 1a. For example, the automotive lamp 1 may be a group of headlights of an automobile. In practical application, a group of headlights of a general automobile can be replaced with the automotive lamp 1 of the present invention, thereby improving the lighting effect of the automobile.

[0026] In a specific embodiment, the automotive lighting device 1 of the present invention further includes an auxiliary lighting module 100a. The multi-light-source lighting module 100 and the auxiliary lighting module 100a are integrated into a socket 1a. In one embodiment of the present invention, the multi-light-source lighting module 100 may be a low-beam module, and the auxiliary lighting module 100a may be a high-beam module. In another embodiment of the present invention, the multi-light-source lighting module 100 may be a high-beam module, and the auxiliary lighting module 100a may be a low-beam module.

[0027] As shown in FIG. 1, the multi-light source lighting module 100 includes at least one first optical adjusting element 111, at least one first light source 121, at least one second optical adjusting element 112 and at least one second light source 122.

[0028] As shown in FIG. 1 , the first light source 121 is used to generate a first color light L1 and project the first color light L1 onto the first optical adjusting member 111. This causes the first optical adjusting member 111 to project the first color light L1 forward of the multi-light-source lighting module 100. The second light source 122 is used to generate a second color light L2 and project the second color light L2 onto the second optical adjusting member 112. This causes the second optical adjusting member 112 to project the second color light L2 forward of the multi-light-source lighting module 100. The first color light L1 and the second color light L2 partially or completely overlap each other.

[0029] The first light source 121 and the second light source 122 are used to generate a first color light L1 and a second color light L2, respectively. The first color light L1 and the second color light L2 have light sources of different wavelengths, colors, or color temperatures. For example, the first color light L1 is white light, and the second color light L2 is yellow light. In a specific embodiment, the first light source 121 and the second light source 122 are light-emitting diodes (LEDs). However, the fact that the first light source 121 and the second light source 122 are LEDs is merely one embodiment of the present invention and does not limit the scope of the present invention. The first light source 121 and the second light source 122 may also be other types of light sources.

[0030] The above-mentioned first optical adjusting member 111 and second optical adjusting member 112 in the present invention may be a reflector cup or a lens.

[0031] As shown in FIG. 1 , the first optical adjusting member 111 and the second optical adjusting member 112 are reflector cups and are installed in the socket 1a. The first optical adjusting member 111 and the second optical adjusting member 112 are arranged with a gap between them. A first light source 121 and a second light source 122 are also installed in the socket 1a. The first light source 121 and the second light source 122 project the generated first color light L1 and the second color light L2 toward the first optical adjusting member 111 and the second optical adjusting member 112, respectively. The first optical adjusting member 111 and the second optical adjusting member 112 reflect the first color light L1 and the second color light L2, respectively, and project the first color light L1 and the second color light L2 toward the front of the multi-light-source lighting module 100. The first color light L1 and the second color light L2 partially or completely overlap each other. The first optical adjusting member 111 and the second optical adjusting member 112 shown in FIG. 1 may be disposed in the socket 1a as separate members.

[0032] As shown in Figures 2 and 3, in another embodiment, the first optical adjusting member 111 and the second optical adjusting member 112 are each a reflector cup, and their edges are connected to each other to form a single unit. The first optical adjusting member 111 and the second optical adjusting member 112, which are connected to form a single unit, can be simultaneously inserted into the socket 1a, which is advantageous for production and installation. The differences between Figures 2 and 3 are as follows: In the embodiment of Figure 2, adjacent reflector cups must be spaced apart, so they are connected via horizontally extending edges. Meanwhile, in the embodiment of Figure 3, adjacent reflector cups are arranged consecutively, so they are directly connected at their edges.

[0033] 3, in one or more embodiments of the present invention, the first light source 121 and the second light source 122 are arranged adjacent to each other. The plurality of first light sources 121 and the plurality of second light sources 122 are closely arranged to form a light source array. Each of the first light source 121 and each of the second light sources 122 is arranged corresponding to a reflector cup as the first optical adjusting member 111 and the second optical adjusting member 112, respectively, and may project corresponding color light in different angle ranges.

[0034] 3, the first light source 121 and the second light source 122 may be closely arranged. For example, a plurality of first light sources 121 and a plurality of second light sources 122 may be closely arranged to form a light source array 120. Each of the first light sources 121 and each of the second light sources 122 may be arranged corresponding to a reflector cup as the first optical adjusting member 111 and the second optical adjusting member 112, respectively. The first optical adjusting member 111 is mainly used to reflect the first color light L1 generated by the first light source 121, and the second optical adjusting member 112 is mainly used to reflect the second color light L2 generated by the second light source 122. In practical application, the first optical adjusting member 111 may reflect a portion of the second color light L2, while the second optical adjusting member 112 may reflect a portion of the first color light L1. The reflected first color light L1 and second color light L2 are projected forward from the multi-light-source lighting module 100. Furthermore, the first color light L1 and the second color light L2 partially or completely overlap each other.

[0035] As shown in FIG. 4 , the first light source 121 and the second light source 122 may be combined to form a single color-changeable light emitting module 12. The color-changeable light emitting module 12 can be used to generate a first color light L1 and a second color light L2. For example, the color-changeable light emitting module 12 can be a two-chip encapsulated light emitting diode device and can be used to generate light of different colors. The projection ranges of the first color light L1 and the second color light L2 overlap. For example, the first color light L1 and the second color light L2 can both enter the first optical adjusting member 111 and the second optical adjusting member 112 and be projected forward of the multi-light-source lighting module 100 via adjacent optical paths. The first color light L1 and the second color light L2 also overlap.

[0036] Please refer to FIGS. 5 and 6. FIG. 5 is a plan cross-sectional view of the multi-light source lighting module 100, and FIG. 6 is a side cross-sectional view of the multi-light source lighting module 100. The first optical adjusting member 111 and the second optical adjusting member 112 may be combined to form a single reflector cup 110 having a continuous curved surface, and the first light source 121 and the second light source 122 may be provided within the reflector cup 110. Specifically, the reflector cups as the first optical adjusting member 111 and the second optical adjusting member 112 can be obtained by cutting a single optical cup into two parts. In FIG. 6, the second light source 122 is blocked by the first light source 121, so only the first light source 121 is shown in FIG. 6.

[0037] 7, in another embodiment, the first optical adjusting member 111 may be a reflector cup, and the second optical adjusting member 112 may be a lens. The first light source 121 faces the first optical adjusting member 111, and the first color light L1 generated by the first light source 121 is reflected by the first optical adjusting member 111. The second color light L2 generated by the second light source 122 is refracted by the second optical adjusting member 112. As a result, the reflected first color light L1 and the refracted second color light L2 are partially or completely superimposed on each other.

[0038] 8, a third optical adjusting member 113 may be provided on the optical path of the first color light L1. In this way, the first color light L1 reflected by the first optical adjusting member 111 is projected onto the third optical adjusting member 113, and the first color light L1 is projected forward of the multi-light-source illumination module 100 via the third optical adjusting member 113. For example, the third optical adjusting member 113 may be a projection lens.

[0039] In addition, the third optical adjusting member 113 may be connected to the second optical adjusting member 112 and form an extension of the second optical adjusting member 112. For example, the first light source 121 may be located on both sides of the second light source 122, and the third optical adjusting member 113 may be located on both sides of the second optical adjusting member 112.

[0040] In one embodiment of the present invention, as shown in FIGS. 9 and 10, the first optical adjusting member 111 and the second optical adjusting member 112 may be arranged as two independent lens units, spaced apart or closely spaced apart.

[0041] 11, the automotive lighting device 1 includes a multi-light source lighting module 100 and an auxiliary lighting module 100a, which may be integrated into a socket 1a. The multi-light source lighting module 100 includes a first optical adjusting member 111, a first light source 121, a second optical adjusting member 112, and a second light source 122. For example, the multi-light source lighting module 100 is a low beam, and the auxiliary lighting module 100a is a high beam.

[0042] In one embodiment of the present invention, the first optical adjusting element 111 and the first light source 121, and the second optical adjusting element 112 and the second light source 122 may be two independent lighting units, or in another embodiment of the present invention, the second optical adjusting element 112 and the second light source 122 may be integrated into the auxiliary lighting module 100a.

[0043] As shown in FIG. 12 , the multi-light source lighting module 100 includes a first optical adjusting member 111, a first light source 121, two second optical adjusting members 112, and two second light sources 122. The first optical adjusting member 111 and the second optical adjusting member 112 are not limited to lenses with a single optical axis. The first optical adjusting member 111 may be a lens with a single optical axis and is disposed on the optical path of the first color light L1 generated by the first light source 121. The second optical adjusting member 112 may be an optical diffusing member having a diffusing function, such as a diffusion sheet. The surface of the second optical adjusting member 112 may have an uneven diffusing surface. The second optical adjusting member 112 is disposed on the optical path of the second color light L2 generated by the second light source 122. The second optical adjusting member 112 may also be a reflective diffusing member. In this case, the second color light L2 generated by the second light source 122 is projected onto the second optical adjusting member 112, and then reflected by the second optical adjusting member 112 in a predetermined direction or area.

[0044] 13 , the multi-light source lighting module 100 further includes a control circuit 130 and a switch 140. The control circuit 130 is used to control the on / off of the first light source 121 and the second light source 122. For example, the control circuit 130 may be a multi-stage switching device. The switch 140 may be a high beam selector switch or a passing selector switch of a vehicle. The switch 140 is used to transmit a trigger signal to the control circuit 130.

[0045] When the first light source 121 is on, the control circuit 130 turns the second light source 122 on or off with one cycle consisting of receiving a specific number of trigger signals. For example, the control circuit 130 turns the second light source 122 on every three triggers of the switch 140. When triggered again, the control circuit 130 turns the second light source 122 off until the switch 140 triggers three times again to turn the second light source 122 on again.

[0046] Specifically, the multi-light source lighting module 100 of the present invention may have three operating modes, among which, in the first operating mode, neither the first light source 121 nor the second light source 122 emits light, and is usually used in daytime or in a driving environment with sufficient lighting.

[0047] In the second operating mode, the first light source 121 and the second light source 122 of the multi-light-source lighting module 100 can emit light simultaneously. First, the first light source 121 is turned on to generate the first colored light L1, but the second light source 122 does not emit light. When the control circuit 130 receives a trigger signal a specific number of times while the first light source 121 is on, it turns on the second light source 122 to generate the second colored light L2 based on that cycle, and also keeps the first light source 121 on to generate the first colored light L1. This allows the multi-light-source lighting module 100 to simultaneously emit the first colored light L1 and the second colored light L2. This is typically used at night or in driving environments with insufficient lighting.

[0048] 14, the first light source 121 and the second light source 122 may be turned on simultaneously (e.g., in the second operating mode). Therefore, the control circuit 130 may include a first driver 131 and a second driver 132. The first driver 131 is used to supply power to the first light source 121, and the second driver 132 is used to supply power to the second light source 122. The two drivers can supply sufficient power to the first light source 121 and the second light source 122. This prevents a situation in which the brightness of the first color light L1 and the second color light L2 is insufficient due to a current that can be output by a single driver being too low.

[0049] 14 shows the first driver 131 and the second driver 132 integrated into the control circuit 130, this is merely one embodiment of the present invention and does not limit the scope of the claims of the present invention. In another embodiment, the first driver 131 and the second driver 132 may be external to the control circuit 130. For example, the first driver 131 is located between the control circuit 130 and the first light source 121, and the second driver 132 is located between the control circuit 130 and the second light source 122.

[0050] In the third operating mode, only one of the first light source 121 and the second light source 122 of the multi-light source lighting module 100 is turned on. In this case, when the first light source 121 is off, the control circuit 130 turns on the second light source 122 based on the cycle upon receiving a specific number of trigger signals. Also, when the first light source 121 is on and the low beam module is on, the control circuit 130 turns on the second light source 122 based on the cycle upon receiving a specific number of trigger signals, and turns off the first light source 121.

[0051] 15 , when the first light source 121 and the second light source 122 cannot be turned on at the same time, the total power required to turn on the light sources and maintain sufficient illuminance is small. In this case, the control circuit 130 only includes a driver 133 and a switch 134. The driver 133 is used to supply power to the switch 134 and output the power to the first light source 121 or the second light source 122 via the switch 134.

[0052] 15 shows the driver 133 integrated within the control circuit 130, this is merely one embodiment of the present invention and is not intended to limit the scope of the claims. In other embodiments, the driver 133 may be external to the control circuit 130.

[0053] In practical application, the headlight cluster of a general vehicle can be directly replaced with the multi-light source lighting module 100 of the present invention, and by adjusting the vehicle lighting control lever inside the vehicle, the vehicle can generate illumination light sources in bad weather. In other words, the headlight cluster of the present invention can be quickly and easily installed on a general vehicle, improving the safety of the vehicle when driving.

[0054] The above description is merely a preferred embodiment of the present invention and does not limit the scope of the present invention. That is, all equivalent modifications and additions based on the shape, structure, features and spirit described in the claims of the present invention are included in the claims of the present invention.
