Description

Lamp control method

Technical Field

The invention relates to the technical field of illumination, in particular to a control method of a lamp.

Background

The festival string lights have various shapes and flashing lights, so that the festival string lights have lighting and decorative effects at night, and are the first choice for people to add festival atmosphere in the festival. The lighting decorative effect sends a control signal with a duty ratio to the LED lamp through the controller, and the control signal enables the LED lamp to generate various different flashing light effects.

The existing LED lamp controller comprises a control unit and a switch unit, wherein the switch unit is connected to the output end of the control unit, the control unit is usually a programmable chip, the switch unit forms two groups of switch circuits through four triodes, and the two groups of switch circuits are controlled to be alternately conducted through the control module so as to realize alternate flashing of two street lamp strings connected to the output end. The two sets of switch circuits have the following problems:

1, only two loads can be connected, and each load is usually a light string, so that the quantity of the light strings which can be connected by the existing switch unit is small, and the light effect generated during working is limited.

And 2, when one of the switch circuits is damaged, the lamp string connected with the switch circuit cannot work, and only the other switch circuit can work at the moment, so that the effect of the lamp string is poorer.

And 3, the four triodes in the switch unit form a group of switch circuits by two triodes at opposite angles, and the structure leads to complex circuit structure, needs more wiring and increases the cost. In each switch circuit, only one triode is electrically connected with the control module, that is, in each group of switch circuits, only one triode is controlled by the control module to be turned on or off, and the on or off of the other triode is determined according to the state of the previous triode, so that the other triode cannot be independently controlled.

In the fourth aspect, the controller may be configured to switch the blinking pattern of the light only, and has no other function, and thus has a disadvantage of having a single function.

Disclosure of Invention

Aiming at the technical problems, the invention provides a lamp control method, which can switch the flickering mode of the lamp and set the working time of the lamp.

The technical scheme for solving the technical problems is as follows:

the control method of the lamp comprises the following steps:

s1, after power-on, a control unit outputs a control signal, and the control unit receives an input switching signal from a mode selector;

s2, if the control unit judges that the switching signal input by the mode selector is a lamplight flickering mode switching signal, the control unit outputs a flickering mode switching control signal to the switch unit, and the flickering mode switching control signal controls the switching unit to be switched on or off in order;

and S3, if the control unit judges that the switching signal input by the mode selector is a lamplight timing signal, the control unit controls and outputs the operation for timing the control signal according to the input of the mode selector, and when the timing time is over, the control unit stops outputting the control signal.

The control unit outputs a control signal for enabling the lamp to work after power is on, if the control unit receives a timing switching signal sent by the mode selector, the control unit switches the operation of the control unit for outputting the timing control signal according to the input of the mode selector, and when the timing time is over, the control unit stops outputting the control signal.

After the control unit sends operation signals to the control unit in different modes, the control unit recognizes the input signals to obtain the switching of the lamplight flickering mode or the lamplight working time setting, and after the control unit obtains a specific conclusion, the control unit outputs corresponding control instructions to control the lamp to work. Therefore, the invention can switch the flickering mode of the lamp light and set the working time of the lamp light, so that the functions of the invention are diversified.

As shown in fig. 3 and 4, the three wires and the four-way lamp form a three-wire four-way lamp 3a. However, the lamp 3a of the present embodiment is not limited thereto, and for example, as shown in fig. 5, the lamp further includes a fifth LED lamp 11, a sixth LED lamp 12, wherein the anode end of the fifth LED lamp 11 is connected to the first wire 4, and the cathode end of the fifth LED lamp 11 is connected to the third wire 6; the cathode terminal of the sixth LED lamp 12 is connected to the first wire 4, and the anode terminal of the sixth LED lamp 12 is connected to the third wire 6.

As shown in fig. 7, the embodiment further provides a control method of the lamp, including the following steps:

s1, after power-on, a control unit 2 outputs a control signal, and the control unit 2 receives an input switching signal from a mode selector; if the controller has a memory chip U3, before the last power-off, the memory chip U3 records the control signal of the current lighting mode output by the control unit 2, and after the next power-on, the control unit 2 reads the control of the lighting mode output last time from the memory chip 3 and outputs the control signal as the control signal of the lighting mode after the power-on. If the memory chip 3 is not present in the controller, the control unit 2 outputs a light emission pattern in accordance with the program setting. The mode selector is a key switch SW or a touch switch connected to the control unit 2, and the mode selector may also employ a wireless signal transmitter.

S2, if the control unit 2 judges that the switching signal input by the mode selector is a lamplight flickering mode switching signal, the control unit 2 outputs a flickering mode switching control signal to the switch unit 3, and the flickering mode switching control signal controls the on-off order of the switch unit 3;

in step S2, the control unit 2 determines that the switching signal input by the mode selector is a light blinking mode switching signal according to the following criteria: the mode selector is pressed once and the time of pressing is less than or equal to the first time set by the control unit 2. For example, the time of a single press does not exceed 1 second. The key switch SW or the touch switch is turned on or off, and preferably, the key switch SW or the touch switch is turned on, so that the time of a single press is not more than 1 second, that is, the time of a single press is not more than 1 second.

The wireless signal transmitter is provided with a plurality of selection buttons, after each selection button is operated, the wireless signal transmitter can send out corresponding coding signals, the coding signals corresponding to each button are inconsistent, and after the control unit 2 receives the coding signals, the control unit is compared with the coding signals to identify a specific mode corresponding to the coding signals, such as a flash mode or a timing mode of the lamp 3 a.

If the wireless code signal for switching the flash mode is output through the wireless signal transmitter, the control unit 2 receives and recognizes the wireless code signal for switching the flash mode transmitted from the wireless signal transmitter through the wireless signal receiver U4, thereby outputting a control signal for changing the flash mode of the lamp 3 a.

And S3, if the control unit 2 judges that the switching signal input by the mode selector is a lamplight timing signal, the control unit 2 controls and outputs the operation for timing the control signal according to the input of the mode selector, and when the timing time is over, the control unit 2 stops outputting the control signal, and at the moment, the lamp is turned off.

In step S3, the control unit 2 determines that the switching signal input by the mode selector is a light timing signal according to the following criteria: pressing the mode selector a plurality of times within a second time set by the control unit 2; for example, the key switch SW or the touch switch is continuously pressed twice within 1 second, i.e. the second time is within 1 second, so that the control unit 2 obtains a signal that the mode selector is turned on twice continuously within 1 second, thereby judging that the user makes the lamp enter the clocked operating mode through the mode selector.

In step S3, the control unit 2 may further determine that the switching signal input by the mode selector is a light timing signal according to the following criteria: the time for which the mode selector is continuously pressed is greater than or equal to the third time set by the control unit 2, for example, the time for which the key switch SW is continuously pressed is greater than 2 seconds, that is, the third time is greater than 2 seconds.

After entering the timer mode, if the control unit 2 also receives the light blinking mode switching signal, the blinking mode is switched in the timer mode in the manner of step S2.

When the mode selector employs the push switch SW or the touch switch, after entering the timer mode, if the control unit 2 receives the switching signal from the mode selector again as the lamp light timer signal, the timer is turned off.

If the timing mode is selected wirelessly, the control unit 2 receives the code for timing sent from the wireless signal transmitter through the wireless signal receiver U4, for example, the control unit 2 is used for starting timing after acquiring the second code, and sets the time for timing operation, for example, the lamp 3a is turned off after operating for 6 hours. Of course, various codes for timing may be transmitted to the wireless signal transmitter, for example, a third code for timing may be transmitted, and the third code for timing may be turned off after the lamp 3a is operated for 8 hours. The control unit 2 is used for starting timing after the coding of timing, and the control unit 2 is used for stopping timing after receiving the coding signal for canceling the timing.

When any one of fig. 4 or fig. 5 and fig. 11a to fig. 36f is connected, or any one of fig. 8 to fig. 10 is the control unit and the switching unit of fig. 37a to fig. 42f, the controller is adapted to control each lamp.

The control method of the present invention is not limited to the above-described embodiment, for example:

(a) In step S2, the control unit 2 determines that the switching signal input by the mode selector is the basis of the light blinking mode switching signal is: the mode selector is pressed a plurality of times within a second time set by the control unit 2, for example, the key switch SW or the touch switch is pressed twice in succession within 1 second.

(b) In step S2, the control unit 2 determines that the switching signal input by the mode selector is the basis of the light blinking mode switching signal is: the time for continuously pressing the mode selector is greater than or equal to the third time set by the control unit 2, for example, the time for continuously pressing the key switch SW is greater than 2 seconds.

(c) In step S3, the control unit 2 determines that the switching signal input by the mode selector is a light timing signal according to the following criteria: the mode selector is pressed once and the time of pressing is less than or equal to the first time set by the control unit 2. For example, the time per press does not exceed 1 second.

The last control method is based on that the controller can switch the light flashing mode switching signal and the light timing signal respectively, for some controllers, only the timing of the light is needed to be switched, the light flashing mode is automatically realized by a program without switching, for example, eight flashing modes are needed, after power-on, the eight flashing modes can be output and circulated in turn, and for such controllers, the invention also configures the following control method:

after power-up, the control unit 2 outputs a control signal for operating the lamp, the control signal is in the above-described eight cycle flashing modes, if the control unit 2 receives a timing switching signal sent by the mode selector, the control unit 2 switches the operation of the control unit to output the timing control signal according to the input of the mode selector, and when the timing time is over, the control unit 2 stops outputting the control signal.

The mode selector is a key switch SW or a touch switch connected with the control unit 2, and the control unit 2 judges that the basis of the mode selector for sending the timing switching signal is as follows: pressing the mode selector once and the time of pressing is less than or equal to the first time set by the control unit 2, for example, the first time is within 1 second; or the mode selector is pressed a plurality of times within a second time set by the control unit 2, for example, the key switch SW or the touch switch is continuously pressed twice within 1 second. Or the duration of pressing the mode selector is greater than or equal to the third time set by the control unit 2, and the duration of pressing the key switch SW is greater than 2 seconds.

The light brightness or the switch controller can also be switched by operating the key switch SW or the touch switch, for example, the mode selector is pressed once, and the pressing time is less than or equal to the first time set by the control unit 2, for example, the first time is within 1 second, both in the working mode after power-up and in the working mode after entering the timer; or the mode selector is pressed a plurality of times within a second time set by the control unit 2, for example, the key switch SW or the touch switch is continuously pressed twice within 1 second. Or the duration of pressing the mode selector is greater than or equal to the third time set by the control unit 2, and the duration of pressing the key switch SW is greater than 2 seconds. For another example, the controller is turned on or off by continuously pressing the mode selector for a time greater than or equal to the third time set by the control unit 2.

For the operation of the timer mode and the operation of switching the brightness of the light, both are realized by operating the same key switch, but the modes of sending signals are different, for example, when the mode selector is pressed once for switching the brightness in the first time, the mode selector is pressed for multiple times in the second time set by the control unit 2 to enter or exit the timer mode, that is, the operations of the timer and the dimming and the switch controller are not overlapped.

Of course, all the operations described above may employ two key switches SW or touch switches, one for switching the light brightness or switch controller, and the other for entering or exiting the timing.
