In order to more clearly describe the technical contents of the present invention, the following further description is given in conjunction with specific embodiments.

The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with the present application. Rather, they are merely examples of apparatus and methods consistent with certain aspects of the present application, as detailed in the appended claims.

In this embodiment, the first start operation signal is:

pressing a first key for a long time;

the second starting operation signal is as follows:

and pressing the second key for a short time.

In other embodiments, the first start operation signal and the second start operation signal may be formed by signals of other operation forms.

The first key and the second key can be formed by the same key or two keys respectively.

In this embodiment, the same power activation key constitutes the first key and the second key. In other embodiments, the first key and the second key may be formed by different keys, for example, the first key may be formed by a power start key, and the second key may be formed by a brightness reduction key.

In an embodiment, the above-mentioned explosion-proof lamp driving control method can be implemented by using an explosion-proof lamp driving control circuit, wherein the explosion-proof lamp driving control circuit includes the main control module, the key module, the driving module and the power module;

the key module is connected with the main control module and used for providing operation signals to the main control module, wherein the operation signals comprise the first starting operation signal and the second starting operation signal;

the power module is connected with the first input end of the driving module, the output end of the driving module is connected with the light source module in the explosion-proof lamp, and the first output end of the main control module is connected with the second input end of the driving module.

In this embodiment, the driving module is composed of a multi-gear brightness driving module, and the operation signal further includes a brightness increasing signal and a brightness decreasing signal; the key module comprises a power supply starting key, a brightness increasing key and a brightness reducing key;

the power supply starting key is connected with a starting signal receiving end of the main control module and used for providing the first starting operation signal and the second starting operation signal for the main control module;

the brightness increasing key is connected with a brightness increasing signal receiving end of the main control module and used for providing the brightness increasing signal for the main control module;

the brightness reducing key is connected with a brightness reducing signal receiving end of the main control module and used for providing the brightness reducing signal for the main control module.

In other words, in this embodiment, the first key outputting the first start operation signal and the second key outputting the second start operation signal are both constituted by a power start key.

In this embodiment, the circuit further includes a prompt module, and the second output terminal of the main control module is connected to the prompt module. The prompt module displays the start prompt information, and a user can execute corresponding operation according to the start prompt information after inputting the first start operation signal, so that a second start operation signal is input. The prompting module can display starting prompting information and also can display some warning information or other information.

In the embodiment, the main control module is composed of a singlechip,

the first input end of the single chip microcomputer forms a starting signal receiving end of the main control module, namely the first input end of the single chip microcomputer is connected with the power supply starting key;

the second input end of the single chip microcomputer forms a brightness increasing signal receiving end of the main control module, namely the second input end of the single chip microcomputer is connected with the brightness increasing key;

the third input end of the single chip microcomputer forms a brightness reduction signal receiving end of the main control module, namely the third input end of the single chip microcomputer is connected with the brightness reduction key;

the first output end of the single chip microcomputer forms the first output end of the main control module;

and the second output end of the singlechip forms the second output end of the main control module.

In this embodiment, the multi-gear brightness driving module may be composed of a PWM wave control module, where the PWM wave control module may be composed of a controllable switching tube, for example, a controllable switching tube such as an IGBT (insulated gate bipolar transistor) and an MOS (metal oxide semiconductor field effect transistor), and the duty ratio of the driving signal may be adjusted to control the on-time of the controllable switching tube, so as to drive the explosion-proof lamp to perform brightness illumination in different gears.

In the embodiment, the PWM control module is adopted to form the multi-gear brightness driving module, so that when the main control module generates a driving signal to drive the explosion-proof lamp to illuminate, the soft start of the explosion-proof lamp is controlled by using a pulse width modulation mode (namely, a PWM method) (namely, the main control module generates the driving signal to gradually increase the voltage transmitted to the light source module, so that the explosion-proof lamp is soft-started to illuminate), thereby avoiding sudden start and voltage rise and causing impact on electrical elements, and ensuring that the explosion-proof lamp has longer service life and is more energy-saving. The pulse width modulation is an analog control mode, and the bias of a transistor base electrode or an MOS tube grid electrode is modulated according to the change of corresponding load to change the conduction time of the transistor or the MOS tube, so that the change of the output of the switching voltage-stabilized power supply is realized. This way the output voltage of the power supply can be kept constant when the operating conditions change, which is a very effective technique for controlling an analog circuit by means of the digital signal of the microprocessor. Pulse width modulation is a very efficient technique for controlling analog circuits using the digital output of a microprocessor, and is widely used in many fields ranging from measurement, communications to power control and conversion.

In other embodiments, the driving module may also be formed by a switch module;

the input end of the switch module forms the first input end of the drive module, the output end of the switch module forms the output end of the drive module, and the control end of the switch module forms the second input end of the drive module.

In the embodiment, when the driving signal is high level, the switch device is switched on, the voltage on the power module is transmitted to the light source module, the explosion-proof lamp is driven to illuminate, and when the driving signal is low level, the switch device is switched off, the voltage on the power module is not transmitted to the light source module, and the explosion-proof lamp is not driven to illuminate.

In order to make the explosion-proof lamp driving control method more convenient for those skilled in the art, a more specific control example is described below with reference to fig. 1:

during operation of the explosion-proof lamp, the following steps are carried out:

firstly, judging whether a first starting operation signal is received by a main control module;

if the first starting operation signal is received, executing the subsequent step III and generating starting prompt information; if the first starting operation signal is not received, returning to the step (r);

the main control module judges whether a second starting operation signal is received, and specifically: judging whether the second starting operation signal is received within a first preset time interval or not, and whether the received second starting operation signal is a second starting operation signal which accords with the starting prompt message or not;

if the second starting operation signal is received within the first preset time interval and the received second starting operation signal is in accordance with the starting prompt message, the main control module generates a driving signal of a preset gear to drive the explosion-proof lamp to be in soft start for illumination, and continues the subsequent steps; if the second starting operation signal is not received within the first preset time interval or the received second starting operation signal is not in accordance with the starting prompt message, the main control module does not drive the explosion-proof lamp to illuminate;

the main control module judges whether a brightness adjusting signal is received;

sixthly, if the brightness adjusting signal is not received, the main control module keeps outputting the driving signal of the current gear, drives the explosion-proof lamp to illuminate, and returns to the fifth step; if the brightness adjusting signal is received, continuing to perform the following step;

and seventhly, outputting a driving signal of a gear corresponding to the brightness adjusting signal by the main control module according to the brightness adjusting signal, driving the explosion-proof lamp to illuminate, and returning to the fifth step.

Fig. 1 shows the control flow, and fig. 1 is a flow chart of the explosion-proof lamp driving control method according to an embodiment of the invention.

In step (c), if the received brightness adjusting signal is a brightness increasing signal, the main control module outputs a driving signal higher than the current brightness level to drive the explosion-proof lamp to increase the illumination brightness; if the brightness adjusting signal is a brightness reducing signal, the main control module outputs a driving signal lower than the current brightness gear to drive the explosion-proof lamp to reduce the illumination brightness.

In this embodiment, the same key outputs the first start operation signal and the second start operation signal, that is, if the user wants to turn on the explosion-proof lamp, the user needs to press the key for a predetermined time (for example, press the first key for 1.5 seconds), send the first start operation signal to the main control module, and then press the key for a short time again within a first predetermined time interval (for example, within 3 seconds) to complete the start of the explosion-proof lamp, otherwise, the explosion-proof lamp cannot be turned on. Meanwhile, after a user presses the button for a long time and outputs a first starting operation signal, the main control module generates starting prompt information to prompt the user to press a corresponding key in a preset time interval to input a second starting operation signal, and the second starting operation signal can be transmitted to the main control module only if the operation input by the user in the first preset time interval is in accordance with the starting prompt information; if the information input by the user is not accordant with the starting prompt information or exceeds the first preset time interval and then the operation signal is input, the explosion-proof lamp cannot be started successfully. After the explosion-proof lamp is started to illuminate, the brightness of the explosion-proof lamp can be adjusted by the brightness increasing key and the brightness reducing key of the user.

As shown in fig. 2, the explosion-proof lamp driving control circuit in this embodiment includes the main control module, the key module, the driving module, the power module, and the prompt module; the key module comprises a power supply starting key K1, a brightness increasing key K2 and a brightness reducing key K3;

the power supply starting key K1 is connected with a starting signal receiving end of the main control module and used for sending a first starting operation signal and the second starting operation signal to the main control module;

the brightness increasing key K2 is connected with a brightness increasing signal receiving end of the main control module and used for sending a brightness increasing signal to the main control module;

the power module is connected with the first input end of the driving module, the output end of the driving module is connected with the light source module in the explosion-proof lamp, the first output end of the main control module is connected with the second input end of the driving module, and the first output end of the main control module is connected with the prompt module.

The control circuit can be used for executing the explosion-proof lamp driving control method, so that the illumination control of the explosion-proof lamp is realized, and the false start is effectively avoided.

In the drive control method of the explosion-proof lamp, whether a first starting operation signal is received or not is judged by a main control module, and if the first starting operation signal is received, the subsequent steps are executed; if the first starting operation signal is not received, the step is repeatedly executed; the main control module judges whether a second starting operation signal is received, and if the second starting operation signal is received, the main control module generates a driving signal to drive the explosion-proof lamp to illuminate; if the second starting operation signal is not received, the main control module does not drive the explosion-proof lamp to illuminate, and because the two operation signals need to be received at the same time to drive the explosion-proof lamp to illuminate, the probability of false triggering is effectively reduced. By adopting the drive control method and the corresponding drive control circuit of the explosion-proof lamp, the explosion-proof lamp can be used more safely and energy-saving, and has stronger applicability.
