Another core of the invention is to provide a vehicle-mounted light guide device comprising the switch.
In order that those skilled in the art will better understand the disclosure, the invention will be described in further detail with reference to the accompanying drawings and specific embodiments.
Referring to fig. 1, fig. 2 and fig. 3, fig. 1 is a schematic diagram illustrating a layout of all light emitting panels connected in series in a switch according to an embodiment of the present invention; fig. 2 is a schematic diagram of a switch in which all light-emitting panels are connected in series according to an embodiment of the present invention; fig. 3 is a schematic diagram of a switch according to an embodiment of the present invention, in which all light-emitting panels are connected in parallel.
The switch provided by the embodiment of the invention comprises a plurality of light-emitting panels 2 and a plurality of switch beacons 1, wherein the switch beacons 1 are arranged on the light-emitting panels 2 and used for acquiring a pressing signal of a user, one switch beacon 1 corresponds to one function, the classification of the switch beacons 1 can specifically refer to the prior art, and the light-emitting panels 2 can be directly adhered to a shell containing a plurality of switch beacons 1; and the switch beacons 1 and the light-emitting panels 2 are arranged in one-to-one correspondence, and all the light-emitting panels 2 are connected in series or in parallel. That is, each switch beacon 1 corresponds to one light emitting panel 2, and specifically, the size of the general switch beacon 1 is about 5mm × 5mm, for example, the light emitting panel 2 may be customized to the same size as the switch beacon 1, and then one light emitting panel 2 is pasted below each switch beacon 1.
Accordingly, if all the light emitting panels 2 are connected in series, the lighting and lighting of all the light emitting panels 2 can be synchronously controlled; if all the light-emitting panels 2 are connected in parallel, the on-off of the circuit corresponding to each light-emitting panel 2 can be asynchronously controlled to drive the on-off of one light-emitting panel 2.
Certainly, according to actual needs, the light-emitting panel 2 may be specifically provided with an OLED panel, that is, a flexible OLED panel is introduced to replace a traditional light-guiding manner, the OLED panel is an electroluminescent panel, and the OLED panel is a surface light source, so that the brightness uniformity is over 80%, no glare exists, the spectrum is close to natural light, and the blue-band component is less, so that the light emission is soft and the eyes can be protected; meanwhile, the OLED panel is very thin and can reach 0.88mm, the OLED panel can be bent into a curved surface at will due to the fact that the OLED panel is a flexible panel, and the light source material is organic and degradable and pollution-free.
Therefore, the switch can ensure that the brightness uniformity meets the actual requirement, so that the problems of insufficient and uneven brightness of common light guide can be solved; and simultaneously, synchronous control or independent control of a plurality of panels is realized through series connection or parallel connection of a plurality of light-emitting panels 2, so that the utilization efficiency of the luminous flux of the light-emitting panels 2 is improved.
Further, when all the light emitting panels 2 are connected in series, the switch further includes a first drive control portion 31 connected in series to all the light emitting panels 2, and the first drive control portion 31 is used to control the on/off of the circuit.

In this way, when the first drive control unit 31 outputs the corresponding drive voltage and current, the current of each light-emitting panel 2 is the same, and the luminous flux of the light-emitting panel 2 is the same; when the output is turned off, all the light emitting panels 2 are simultaneously extinguished, and when the output is turned on, all the light emitting panels 2 are simultaneously lit.
When all the light-emitting panels 2 are connected in parallel, the switch is further provided with a second drive control part 32 connected in parallel with any one of the light-emitting panels 2, and the second drive control part 32 is used for controlling the on-off of a circuit where any one of the light-emitting panels 2 is located.

Of course, the first drive control part 31 and the second drive control part 32 may be set to be PCBA according to actual needs, and the PCBA may refer to the prior art, and will not be expanded one by one here.
In the application of the switch panel, as a backlight, when an operator presses the corresponding switch beacon 1, the backlight responds randomly, lights the light emitting panel 2 under the switch beacon 1, thereby feeding back to the operator that the switch is in effect and is in operation. When the operator presses the illuminated switch beacon 1 again, the backlight responds by turning off the light-emitting panel 2 under the corresponding switch beacon 1.
As can be seen from fig. 1, all the light-emitting panel 2 is provided between the switch beacon 1 and the PCBA, and thus, the brightness of the light-emitting panel 2 can be changed by changing the current by merely drawing two control keys on the light-emitting panel 2. Of course, the light-emitting panel 2 may be rigid, fixed by external structure, or flexible, and is directly adhered to the housing of the switch beacon 1, in such a way that the whole surface is lighted and the brightness is uniform, and the brightness of the light source of the light-emitting panel 2 is generally 3000cd/m2Left and right, sufficient to switch beacon 1 illumination.
