It should be understood that the specific embodiments described herein are merely illustrative of the present application and are not intended to limit the present application.
In one embodiment, referring to fig. 1, there is provided an emergency marker lamp including a control device (not shown), a plurality of light emitting units 110, and a plurality of switching circuits equal to the number of the light emitting units 110, one light emitting unit 110 corresponding to one switching circuit. One end of the light emitting unit 110 is connected to the power supply voltage VCC, the other end is connected to the input end of the corresponding switch circuit, the control end of each switch circuit is connected to the control device, and the output end of each switch circuit is grounded. It should be noted that fig. 1 only shows a schematic diagram of connection between two light emitting units 110 and corresponding switch circuits, actually, the number of the light emitting units 110 and the switch circuits included in the emergency marker lamp may be more than two, and the ellipses between the light emitting units 110 in fig. 1 indicate that there may be other light emitting units 110 and corresponding switch circuits.
The supply voltage VCC is a voltage required for the light emitting unit 110 to operate normally. One end of the light emitting unit 110 is connected to the power supply voltage VCC, and specifically, the power supply module is connected to the power supply voltage VCC through the power port, that is, the power supply module outputs the power supply voltage VCC to the light emitting unit 110 through the power port. Among them, the light emitting unit 110 is a device that displays evacuation information by emitting light. The switching circuit at least comprises a switching tube, and the input end, the output end and the control end of the switching tube are respectively used as the input end, the output end and the control end of the switching circuit; when the switch tube is switched on, the switch circuit is switched on, the switch tube is switched off, and the switch circuit is switched off. Each switching circuit controls the on/off of the correspondingly connected light-emitting unit 110, when the switching circuit is switched on, the loop where the correspondingly connected light-emitting unit 110 is located is powered on, and the light-emitting unit 110 is on under the action of the power supply voltage VCC; when the switching circuit is turned off, the circuit in which the light emitting unit 110 connected to the switching circuit is located is turned off, and the light emitting unit 110 is not lit.
The control device outputs a first level signal to the control end of each switch circuit in a first working mode to control each switch circuit to be conducted; the control device outputs a first level signal to the control end of the switch circuit of the first part and outputs a second level signal to the control end of the switch circuit of the second part except the first part under the second working mode, and the switch circuit of the first part is controlled to be switched on and the switch circuit of the second part is controlled to be switched off. Wherein the sum of the number of switching circuits of the first part and the number of switching circuits of the second part is equal to the total number of switching circuits. In fig. 1, Q1 denotes a switching tube of the switching circuit of the first part, and Q2 denotes a switching tube of the switching circuit of the second part. The switching circuits of the first and second portions may not be fixed, and may be selected from the total number of switching circuits as needed.
The first level signal is a high level signal for turning on the switching circuit, and the second level signal is a low level signal for turning off the switching circuit. The control device outputs a first level signal to the control end of the switch circuit to control the switch circuit to be switched on, and outputs a second level signal to the control end of the switch circuit to control the switch circuit to be switched off. Specifically, the control device controls all the switch circuits to be turned on in the first operation mode, and at this time, all the light emitting units 110 are powered on and in a bright state; in the second operation mode, the control device controls the on state of the first part of the switch circuits and the off state of the second part of the switch circuits, at this time, the light emitting units 110 corresponding to the first part of the switch circuits are powered on, and the light emitting units 110 corresponding to the second part of the switch circuits are not powered on, so that the light emitting units are turned off. Therefore, the number of the light emitting units 110 in the first operation mode is greater than the number of the light emitting units 110 in the second operation mode; the greater the number of lights of the light emitting unit 110, the greater the brightness of the emergency marker lamp as a whole visually perceived from the human eye, and thus the brightness of the emergency marker lamp in the first operation mode is greater than the brightness in the second operation mode.
Further, the control device can also output a second level signal to the control end of each switch circuit in the third working mode to control each switch circuit to be turned off. At this time, all the switching circuits are turned off, and thus all the light emitting cells 110 are in a turned-off state. Specifically, the control device may include one controller, and all the switch circuits are connected to the same controller; the control device may include a plurality of controllers, and one controller may be connected to each of the switching circuits.
In the emergency marker light, each switch circuit controls the on/off of the light emitting unit 110 on the corresponding loop, and the control device controls the on/off of each switch circuit to control the on/off of the light emitting unit 110 on different loops. The control device works in different working modes to control the conduction of different numbers of switch circuits, so as to control the number of the light-emitting units 110 in a bright state, and further control the overall brightness of the emergency marker lamp. Therefore, brightness adjustment is achieved by controlling the number of the light sources, attention of a user can be brought to by adjusting brightness, and an emergency indication effect is good.
Specifically, the control device may switch to the first operating mode when the emergency condition is satisfied. The emergency condition refers to a condition that emergency evacuation is required, and may include that an emergency evacuation instruction is received, and the current time belongs to a preset time period.

For example, in one embodiment, the second operation mode includes a plurality of operation levels, and the number of the switching circuits of the first portion corresponding to each operation level is different. In this way, the number of switching circuits turned on at different operation levels is different, so that the number of light emitting units 110 in a bright state is different; in this way, various brightness level adjustments can be made in the second mode of operation. For example, in one class of operation, half of the number of switching circuits are the first portion of switching circuits and the other half of the number of switching circuits are the second portion of switching circuits. Further, the control device can select which working grade to work at according to actual needs.
In one embodiment, the light emitting unit 110 includes a plurality of light emitting devices connected in series, and one end of each of the light emitting devices is connected to the supply voltage VCC, and the other end of each of the light emitting devices is connected to the input terminal of the corresponding switch circuit.

And the LED is adopted, so that the luminous effect is good and the brightness is high. It is understood that in other embodiments, the light emitting unit 110 may also be an assembly formed by a plurality of light emitting devices in series and mixed. For example, a plurality of light emitting devices may be connected in series to form a unit, and a plurality of units may be connected in parallel to form the light emitting unit 110.
In one embodiment, the emergency marker light further comprises an ambient light sensor (not shown) connected to the control device. The ambient light sensor senses ambient brightness to obtain a brightness value and sends the brightness value to the control device, the control device switches to the second working mode when the brightness value is smaller than a preset value, and switches to the first working mode when the brightness value is larger than or equal to the preset value.
The preset value can be specifically set according to actual needs, for example, the preset value can be set as an environment brightness value when the emergency marker lamp enters night in a scene needing to be applied. Generally, when the ambient brightness is relatively low, the brightness display of the emergency marker lamp is relatively obvious, and when the ambient brightness is relatively high, the brightness display of the emergency marker lamp is not obvious. The ambient light sensor is used for detecting the ambient brightness, the brightness value of the ambient brightness is compared with the preset value, if the brightness value is smaller than the preset value, the brightness ratio of the current environment is low, at the moment, the second working mode is switched, one part of the light-emitting units 110 is controlled to be bright, the other part of the light-emitting units 110 is controlled not to be bright, highlight display is not needed, and energy can be saved. The brightness value is larger than or equal to the preset value and indicates that the brightness is higher in the current environment, at the moment, the first working mode is switched to perform full-bright display, the brightness level is highest, and the brightness of the emergency marker lamp in the current environment can be enhanced. Therefore, the brightness grade is adjusted according to the requirement by combining the ambient brightness, and the using effect is good.
