Abstract
Description
Technical Field
[0001] The present application relates to a vehicle light source switching device, and more particularly to a vehicle light source switching device that can compensate for insufficient illumination range of a light source caused by turning when the vehicle turns or rolls. Background Art
[0002] Nowadays, all types of motor vehicles are equipped with various lights such as headlights, small lights, taillights, turn signals, brake lights, etc., which can be used to alert other drivers or passers-by to the location of oncoming vehicles or the direction of travel. At the same time, they can illuminate the road surface to ensure the driver's driving vision in dim light, thereby improving driving safety.
[0003] However, traditional headlights can only illuminate in a fixed forward direction. When a vehicle is driving at night, they can only illuminate the driver's field of vision in front of the vehicle. When the vehicle turns or drives on dimly lit roads, the position illuminated by the headlights often differs greatly from the direction of travel, often forming lighting blind spots at turns, which greatly increases the danger of night driving.
[0004] In summary, in order to improve the defects of traditional vehicle lights, it is necessary to develop a vehicle light source device that can fill the blind spot when the vehicle turns and rolls, so as to improve the problem of insufficient light source illumination range when the vehicle turns. Utility Model Content
[0005] In view of the above-mentioned defects of traditional car lights, the purpose of this application is to overcome the above-mentioned defects of traditional car lights. Relying on years of professional design, processing and manufacturing experience, and after unremitting research and development and experiments, the applicant has finally developed a vehicle light source switching device to effectively solve the problem of insufficient light source illumination range when the vehicle turns.
[0006] The purpose of this application is to provide a vehicle light source switching device, which includes a lamp, a driver, a sensing module and a processing unit; wherein the lamp is electrically connected to the driver, and the processing unit is electrically connected to the driver and the sensing module respectively; the lamp includes at least a composite lens and multiple light sources.
[0007] The specific structure of the lamp includes: a compound lens, a lens bracket, a high and low beam switching element, a fixing bracket, a first light source board, a second light source board, a reflector, a heat dissipation base, a heat dissipation cover and a heat dissipation fan.
[0008] The composite lens is composed of a first lens and a plurality of second lenses. The first lens is disposed at the bottom of the composite lens, while the plurality of second lenses are disposed at the top of the composite lens. Specifically, the main body of the composite lens is the first lens, and the plurality of second lenses are disposed at the top of the first lens, that is, the plurality of second lenses are disposed within the first lens to form a composite lens.
[0009] The composite lens is fixedly engaged with the front of the heat dissipation base and the heat dissipation cover by means of a lens bracket, the high and low beam switching element is fixedly arranged in the accommodating space inside the heat dissipation base by means of a fixing bracket, and the first light source board is also fixedly arranged in the accommodating space inside the heat dissipation base and is located above the fixing bracket, and a first light source is arranged on the first light source board; the reflector is arranged in the accommodating space inside the heat dissipation cover, and its inner side is a reflecting surface, and the second light source board is arranged at the front of the inner side of the heat dissipation cover, and a plurality of second light sources are arranged on the second light source board corresponding to the plurality of second lenses on the upper part of the composite lens; and a heat dissipation fan is arranged below the heat dissipation base and on the other side of the composite lens; wherein the first light source and the plurality of second light sources are a plurality of light sources.
[0010] Preferably, the number of the second lenses is at least two, and the number of the second light sources is therefore at least two, so as to provide lighting for the left or right side when the vehicle turns.
[0011] Preferably, in order to increase light intensity and make the lamp more energy-efficient, the first light source and / or the plurality of second light sources may be light emitting diodes (LEDs).
[0012] Preferably, the first light source and the plurality of second light sources are turned on and off independently, and each of the plurality of second light sources is also turned on and off independently.
[0013] When the vehicle is traveling in a straight line at night or in dim light, the vehicle light source switching device is activated to turn on the first light source. The light emitted by the first light source is reflected by the reflective surface on the inner side of the reflector to the first lens at the bottom of the composite lens. At this time, the multiple second light sources are turned off, and the baffle on the high and low beam switching element blocks part of their light to illuminate the near side of the road ahead. When it is desired to illuminate the far side of the road ahead, the processing unit sends a control signal to the driver to control the baffle on the high and low beam switching element to move downward, so that the light emitted by the first light source can be completely reflected to the first lens to illuminate the far side of the road ahead.
[0014] In addition, the sensing module includes at least a three-axis gyroscope and an angle sensor. When the vehicle turns and rolls at night or in dim light, the three-axis gyroscope and angle sensor in the sensing module sense the vehicle's roll angle value to obtain a roll angle signal. After the roll angle signal is transmitted to the processing unit, the processing unit sends a control signal to the driver based on the roll angle signal to control the opening and closing of multiple second light sources, so that the light emitted by the multiple second light sources illuminates the part that cannot be covered by the first light source during turning and rolling, thereby compensating for the insufficient illumination range of the light source during turning.

[0029] Please refer to Figure 1 , Figure 1 This is a schematic block diagram of the electrical connections of the various components in the vehicle light source switching device of the present application. The vehicle light source switching device 1 includes a lamp 2, a driver 3, a sensing module 5, and a processing unit 4. The vehicle light source switching device 1 is assembled on a vehicle, and the lamp 2 is disposed at the vehicle's headlamp assembly and electrically connected to the driver 3, while the processing unit 4 is electrically connected to the driver 3 and the sensing module 5, respectively. The lamp 2 includes at least a composite lens 201 and multiple light sources (i.e., a first light source 209 and multiple second light sources 210. Please refer to the following description for the detailed structure of the lamp 2). In some embodiments, the sensing module 5 may include at least a three-axis gyroscope and an angle sensor (not shown in the figure).
[0030] Please refer to Figures 2 to 5 , which are respectively a schematic diagram of a lamp, a side view, a bottom view and an exploded view of the lamp assembly of the vehicle light source switching device of the present application.
[0031] The specific structure of the lamp 2 includes: a compound lens 201, a lens bracket 204, a high and low beam switching element 205, a fixing bracket 206, a first light source board 207, a second light source board 208, a reflector 211, a heat dissipation base 213, a heat dissipation cover 214, and a heat dissipation fan 215.
[0032] The composite lens 201 is composed of a first lens 202 and a plurality of second lenses 203. The first lens 202 is disposed at the bottom of the composite lens 201, while the plurality of second lenses 203 are disposed at the top of the composite lens 201. Specifically, the composite lens 201 comprises the first lens 202 as a main body, and the plurality of second lenses 203 are disposed at the top thereof. That is, the plurality of second lenses 203 are disposed within the first lens 202 to form the composite lens 201.
[0033] The compound lens 201 is fixedly engaged in front of the heat dissipation base 213 and the heat dissipation cover 214 by means of a lens bracket 204. The high and low beam switching element 205 is fixedly set in the accommodating space inside the heat dissipation base 213 by means of a fixing bracket 206. The first light source board 207 is also fixedly set in the accommodating space inside the heat dissipation base 213 and is located above the fixing bracket 206. The first light source board 207 is provided with a first light source 209; the reflector 211 is provided in the accommodating space inside the heat dissipation cover 214, and its inner side is a reflecting surface 212. The second light source board 208 is provided at the front of the inner side of the heat dissipation cover 214, and the second light source board 208 is provided with multiple second light sources 210 corresponding to the multiple second lenses 203 above the compound lens 201; and the heat dissipation fan 215 is provided below the heat dissipation base 213 and is located on the other side of the compound lens 201.
[0034] Preferably, there are at least two second lenses 203 and at least two second light sources 210 , so as to provide lighting for the left or right side when the vehicle turns.
[0035] Preferably, in order to increase light intensity and make the lamp more energy-efficient, the first light source 209 and / or the plurality of second light sources 210 may be light emitting diodes (LEDs).
[0036] Preferably, the first light source 209 and the plurality of second light sources 210 are independently turned on and off, and each of the plurality of second light sources 210 is also independently turned on and off.
[0037] Please refer to Figure 6 , Figure 6 The vehicle light source switching device of the present application utilizes the light distribution pattern of the light emitted by the first light source.
[0038] When the vehicle is driving in a straight line at night or in dim light, the vehicle light source switching device 1 is activated to turn on the first light source 209. The light emitted by the first light source 209 is reflected to the first lens 202 at the bottom of the composite lens 201 by the reflective surface 212 on the inner side of the reflector 211. At this time, the multiple second light sources 210 are in the off state, and the baffle on the high and low beam switching element 205 blocks part of its light to illuminate the near side of the road ahead. When the far side of the road ahead is to be illuminated, the processing unit 4 sends a control signal 7 to the driver 3 to control the baffle on the high and low beam switching element 205 to move downward, so that the light emitted by the first light source 209 can be completely reflected to the first lens 202 to illuminate the far side of the road ahead. Figure 6 It can be seen that when the vehicle is traveling in a straight line, the light emitted by the first light source 209 can evenly illuminate the road ahead.
[0039] Please refer to Figure 7 , Figure 7 This is a light distribution diagram of the light emitted by the first light source when the vehicle light source switching device of the present application turns left and rolls.
[0040] Depend on Figure 7 As can be seen from the figure, when the vehicle turns left and rolls, the light emitted by the first light source 209 is smaller than that of the Figure 6 When a vehicle is traveling in a straight line, the light on the left side is significantly reduced, resulting in insufficient light range when the vehicle turns, which can easily cause unclear vision or blind spots and lead to danger.
[0041] In order to solve the problem of insufficient light range when the vehicle turns, when the vehicle turns and rolls at night or in dim light, the three-axis gyroscope and angle sensor in the sensing module 5 are used to sense the vehicle's roll angle value, and a roll angle signal 6 is obtained. After the roll angle signal 6 is transmitted to the processing unit 4, the processing unit 4 sends a control signal 7 to the driver 3 based on the roll angle signal 6 to control the opening and closing of multiple second light sources 210, so that the light emitted by the multiple second light sources 210 illuminates the part that the first light source 209 cannot cover when turning and rolling, thereby compensating for the insufficient light illumination range during turning.
[0042] Please refer to Figure 8 , Figure 8 In the vehicle light source switching device of the present application, when turning left and rolling, the light emitted by the first light source plus the light emitted by the second light source serve as an auxiliary light distribution pattern.
[0043] Depend on Figure 8 It can be seen that when the vehicle turns left and rolls, the light emitted by the multiple second light sources 210 can indeed illuminate the part that is not covered by the first light source 209 when turning left and rolling, thereby making up for the range of insufficient light illumination and improving the safety of the vehicle when driving and turning at night or in dim light.
[0044] In summary, the vehicle light source switching device provided in this application can indeed improve the problem of insufficient illumination range of the vehicle lights when turning when the vehicle is driving at night or in dim light, thereby further improving the safety of vehicle driving at night or in dim light.

In this regard, the examples disclosed herein are for illustrative purposes only and should not be interpreted as limiting the scope of the present disclosure.
