And a reflective member 52 corresponding to the position of the optical transceiver 51, and selectively driving the circuit substrate 3 to supply power to the light-emitting assembly 2, and the optical transceiver 51 includes a transmitting member 511, and at least one is disposed on the transmitting a receiving member 512 on one side of the member 511; and at least one control chip 31 The circuit board 3 controls the detection frequency of the detection module 5, and the control chip 31 has a timing unit 311 for intermittently emitting light waves at a predetermined interval. The interval is 0.02 seconds to 1 second, and the power-off unit 312 is disposed in the control chip 31. The electrical connection between the circuit board 3 and the detection module 5 is disconnected when the vehicle carrier 6 travels. .

According to the above description, the structure of the present technology can be understood, and according to the corresponding cooperation of the structure, the infrared light sensor can be used to control the light-emitting component 2, and the advantages of wiring convenience, energy saving and power saving advantages are taken into consideration, and the detailed explanation will be As explained below.

Please refer to the first to eighth figures at the same time, which is a perspective view to a block diagram (3) of the preferred embodiment of the present invention. The novel detection module 5 is composed of a light wave transceiver 51 and a reflection member 52, and the light wave transceiver 51 is disposed on the vehicle carrier 6, and the reflection member 52 is disposed on the door 61 (or the light wave transceiver 51 is disposed at The door 61 and the reflector 52 are provided in the vehicle carrier 6). However, since only the light wave transceiver 51 needs to be energized, even if it is necessary to draw a line with the power supply element 4 (vehicle battery), the wiring process can be easily completed. The light-emitting component 2 is an LED light bar, which further simplifies the overall setting difficulty.

In actual use, please refer to the third figure and the fourth figure at the same time. In the case that the general door 61 is tightly closed, the light wave transceiver 51 still emits light waves through the transmitting member 511, and the transmitting member 511 and the receiving member 512 are attached. The light waves are transmitted to the receiving member 512 via the reflector 52, so that the light is not triggered by the circuit board 3 to the light-emitting component 2, so that the light wave is transmitted to the receiving member 512 via the reflector 52. However, when the vehicle carrier 6 is running, the control chip 31 uses the power-off unit 312 to disconnect the electrical connection between the circuit board 3 and the detection module 5 to prevent the detection module 5 from continuing to operate, resulting in waste of power.

Thus, when the opening action of the door 61 required by the user not getting on and off the vehicle occurs, the lighting component 2 can be prevented from being triggered. Actuate while achieving the goal of saving electricity.

Please refer to the seventh and eighth diagrams at the same time. When the door 61 is normally opened, the light wave emitted by the transmitting member 511 cannot be irradiated to the reflecting member 52, and the receiving member 512 naturally cannot receive the light wave. The module 5 determines that the door 61 is in an open state, and drives the circuit board 3 to supply the power supply element 4 to the light-emitting assembly 2. At the same time, the control chip 31 is set by the timing unit 311 for a predetermined time interval (available from 0.02 second to 1). In the setting interval of the second, the transmitting member 511 is controlled to perform intermittent light wave emission to reduce the power consumption of the detecting module 5. Moreover, the light wave emitted by the light wave transceiver 51 is an infrared light wave of 720 nm, which belongs to the wavelength range of visible light, and can increase the visual effect of the welcome pedal 62.

However, the above description is only the preferred embodiment of the present invention, and thus does not limit the scope of the patent of the present invention. Therefore, the simple modification and equivalent structural changes of the present specification and the drawings should be treated similarly. It is included in the scope of this new patent and is given to Chen Ming.
