[0036] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0037] The embodiment of the present invention provides a remote control method for an LED lamp. Figure 1 , Figure 1 A flowchart of a remote control method for an LED lamp provided by an embodiment of the present invention. The method comprises the following steps:

[0038] S101, broadcasting a verification instruction within a preset range so that a target terminal receives and decodes the verification instruction. If the verification instruction is decoded successfully, a feedback instruction is repeatedly sent to the LED controller.

[0039] S102, receiving a feedback instruction and calculating the actual distance between the LED controller and the target terminal.

[0040] S103, controlling the switch of the LED light according to the difference between the actual distance and the preset distance.

[0041] A remote control method for an LED lamp provided in an embodiment of the present invention distinguishes unfamiliar devices through verification instructions. Since the verification instructions are encrypted, unfamiliar devices cannot be remotely controlled. The difference between the calculated actual distance and the preset distance is used as the judgment of the control switch to reduce human control. The influence of signal attenuation is weakened by changing the channel or correcting the distance formula.

[0042] In one implementation, after the LED controller and the target terminal establish a connection for the first time, the target terminal obtains the command control program from the LED controller and exchanges keys with each other. The target terminal can subsequently use the key to decode and verify the command.

[0043] In one implementation, since the verification instruction is encrypted with a key, non-target terminals cannot decode it and cannot maliciously send feedback instructions.

[0044] In one implementation, the target terminal may be a mobile phone, a tablet, or other device capable of short-range communication.

[0045] In one embodiment, see Figure 2 ,exist Figure 1 Based on this, step S102 includes:

[0046] S1021, if the actual curve falls within the curve interval of the preset signal strength, the difference between the actual distance and the preset distance is calculated, and the power supply and switch of the LED lamp are controlled.

[0047] S1022: If the actual curve falls outside the preset signal strength curve range, a channel change instruction is sent to the target terminal to enable the target terminal to reduce the frequency of the feedback instruction wireless channel until the signal attenuation of the feedback instruction is stable and smooth.

[0048] The actual curve is a curve obtained by fitting the feedback command signal strength received within the LED controller cycle, and the curve range of the preset signal strength is a range summarized from a large number of experiments.

[0049] In one implementation, the power supply and the switch are controlled separately, and the safety risk caused by the current at the moment of turning on the switch is avoided.

[0050] In one implementation, if the feedback command signal strength received by the LED controller is within the curve interval, it means that the signal attenuation is stable and there is no obstacle influence. If the feedback command signal strength received by the LED controller is outside the curve interval, it means that the signal attenuation is abnormal and there is obstacle interference, and the channel can be changed to reduce the influence of signal attenuation.

[0051] In one implementation, the actual distance can be calculated based on the degree of signal attenuation.

[0052] In one embodiment, when the LED lamp is powered on and the switch is turned on, the LED lamp is on, and step S103 includes:

[0053] Step 1: If the difference between the actual distance and the preset distance is greater than or equal to zero, it is determined that the LED light is in standby mode.

[0054] Step 2: If the difference between the actual distance and the preset distance is less than zero, it is determined that the LED light is in the on state.

[0055] In one implementation, the preset distance is a distance set by a user, and the preset distance is used by the LED controller as a basis for determining whether the light is on or off.

[0056] In one implementation, the LED lamp is in a standby state where the power is on and the switch is off, thereby reducing the aging of the LED lamp caused by instantaneous high current.

[0057] In one implementation, the LED lamp is in a startup state when the power is on and the switch is turned on, and the LED lamp operates normally.

[0058] In one embodiment, after step S1022, the method further includes:

[0059] The wireless communication distance calculation formula is corrected according to the correction parameter, and the actual distance is calculated using the corrected wireless communication distance calculation formula.

[0060] The correction parameter is the ratio of the mean slope of the curve interval of the preset signal strength to the actual curve slope.

[0061] In one implementation, the actual distance is obtained by using the wireless communication distance calculation formula L=K+201 gD+201 gF.

[0062] In one implementation, the ratio of the mean slope of the curve interval of the preset signal strength to the actual curve slope is less than 1, so the correction parameter σ is less than 1. By adding the correction parameter σ to the wireless communication distance calculation formula, the corrected formula is σL=K+20l gD+20l gF.

[0063] In one implementation, the abnormal amount of signal attenuation caused by obstacles is corrected by adding parameters, thereby reducing errors and improving accuracy.

[0064] In one embodiment, step S1021 may include the following steps:

[0065] Step 1: If the LED light is in standby mode, the actual distance to the target terminal is continuously calculated. If the preset detection time is exceeded, the detection frequency within the cycle is reduced.

[0066] Step 2: If the LED light is in the on state, the transmitting module of the LED controller will be turned off, and the broadcasting of the verification instruction to the preset range will be stopped.

[0067] Reduce the detection frequency within the cycle. For example, the original detection frequency is 10 detection feedback instructions within 10 seconds, and after reduction, it is 5 detections within 10 seconds.

[0068] In one implementation, if the LED light is determined to be in standby mode, it means that the target terminal is wandering within a preset distance, and unnecessary energy consumption is reduced by reducing the detection frequency within the cycle.

[0069] In one implementation, if the LED light is determined to be in the on state, it means that the target terminal is within a preset distance, and there is no need to broadcast the verification instruction within the preset range, thereby reducing unnecessary energy consumption.

[0070] In one embodiment, after step S101, the method further includes:

[0071] The target terminal controls the switch, brightness and color temperature of the LED light by sending control instructions.

[0072] In one embodiment, before step S101, the method further includes:

[0073] If it is detected that the natural light intensity is lower than the preset intensity, the transmitting module of the LED controller is turned on.

[0074] In one implementation, the preset intensity is a pre-set natural light intensity. If the intensity is lower than the preset intensity, the transmitting module of the LED controller is turned on. If the intensity is higher than the preset intensity, the power supply and switch of the LED lamp are automatically turned off, thereby reducing energy consumption.

[0075] Based on the same inventive concept, the present invention also provides a device. Figure 3 , Figure 3 A framework diagram of a device provided in an embodiment of the present invention includes:

[0076] The transmitting module is used to broadcast the verification instruction within a preset range.

[0077] The receiving module is used to receive the feedback instruction and calculate the actual distance between the LED controller and the target terminal.

[0078] The control module is used to control the switch of the LED light according to the difference between the actual distance and the preset distance.
