Further, some of the step operations may be performed in parallel rather than sequentially.

Example 1

The application provides an LED lamp with adjustable illumination parameters, wherein the LED lamp is connected to a power line, the LED lamp comprises an LED lamp body and a control device connected with the LED lamp body, and as shown in fig. 1, the control device specifically comprises:

In order to realize the adjustment of the lighting parameters in the LED lamp, a control device connected with the LED lamp body is added in the existing LED lamp, and the control device has a circuit formed by a plurality of devices, and specifically, the control device comprises a rectifying circuit, a signal demodulation circuit, a signal processing circuit and an LED power supply. The lighting parameters here specifically include at least one of brightness, color temperature, color.

The rectifying circuit is arranged in the control device and is provided with an input end and an output end, the input end of the rectifying circuit is connected with the power line, and the output end of the rectifying circuit is connected with the output end of the signal demodulation circuit. The rectifying circuit can achieve the purpose of taking electricity from the power line, and can acquire the digital coded signal transmitted from the power line and send the acquired digital coded signal to the signal demodulation circuit.

The input end of the signal demodulation circuit is connected with the output end of the rectification circuit, and the output end of the signal demodulation circuit is connected with the input end of the signal processing circuit. This enables the signal demodulation circuit to acquire the digital encoded signal from the rectification circuit, and to perform recognition and demodulation processing on the digital encoded signal, thereby acquiring a demodulated result, and to transmit the demodulated result to the signal processing circuit.

The input end of the signal processing circuit is connected with the output end of the signal demodulation circuit, the demodulated result is obtained from the signal demodulation circuit, decoding is carried out based on the demodulated structure, and a PWM control signal is output based on the decoded result and is transmitted to the LED power supply.

The input end of the LED power supply is connected with the output end of the signal processing circuit so as to acquire a PWM control signal corresponding to the digital coding signal from the signal processing circuit, and the power supply of the LED lamp body is regulated based on the PWM control signal, so that the LED lamp body presents brightness, color or color temperature corresponding to the digital coding signal.

And a diode is further arranged between the signal processing circuit and the LED power supply, and the digital coding signal is prevented from being absorbed by a filter capacitor arranged in the LED power supply based on the unidirectional trafficability of the diode, so that the digital coding signal cannot be identified.

The rectifier circuit provided in the control device is a circuit for converting ac power into dc power. Most rectifying circuits consist of a transformer, a rectifying main circuit, a filter, and the like. It is widely used in the fields of speed regulation of DC motor, excitation regulation of generator, electrolysis and electroplating. The rectifier circuit is typically composed of a main circuit, a filter and a transformer. The main circuit is composed of a multi-purpose silicon rectifying diode and a thyristor. The filter is connected between the main circuit and the load and is used for filtering alternating current components in the pulsating direct current voltage. Whether the transformer is arranged or not depends on the situation. The transformer is used for realizing matching between alternating current input voltage and direct current output voltage and electric isolation between an alternating current power grid and a rectifying circuit. The rectifying circuit is used for converting the alternating current with lower voltage output by the alternating current voltage-reducing circuit into unidirectional pulsating direct current, namely the rectifying process of the alternating current, and mainly comprises a rectifying diode. The voltage after passing through the rectifying circuit is not an ac voltage but a mixed voltage containing a dc voltage and an ac voltage.

And a signal demodulation circuit provided in the control device for demodulating the digitally encoded signal. Demodulation is here the process of recovering a message from a modulated signal carrying the message. In various information transmission or processing systems, a sender modulates a carrier with a message to be transmitted, producing a signal carrying the message. The receiving end must recover the transmitted message to be utilized.

The signal processing circuit provided in the control device decodes the demodulated result, which means a process in which the received symbol or code is restored to information by the receiver, and corresponds to the encoding process. The decoding process is performed because in the generation stage of the digital encoded signal, in consideration of confidentiality and data transmission integrity, the content to be transmitted needs to be encoded, and in the encoding process, a check bit needs to be set, so that the receiving end, that is, the signal processing circuit in this embodiment, can decode according to a predetermined decoding mode after receiving the demodulation result, and extract the check bit in the transmission content to perform a check operation before decoding, and perform decoding after ensuring that the received data is complete data.

The LED power supply arranged in the control device controls the LED power-on time through pulse width adjustment according to the received PWM control signal, and controls the brightness of the LED power supply by controlling the bright time of the LED power supply. Dimming of the LED is accomplished by adjusting the forward current in the LED with a DC signal or filtrate PWM. Reducing the LED current will act to adjust the LED light output intensity, however, a change in forward current will also change the color of the LED, as the chromaticity of the LED will change with a change in current. Many applications (e.g. automotive and LCD TV backlighting) do not allow any color drift of the LEDs. In these applications, a wide range of dimming is necessary because there are different light variations in the surrounding environment and the human eye is sensitive to small variations in light intensity. The dimming of the LED can be accomplished without changing the color by controlling the brightness of the LED by applying a PWM signal.

Pulse Width Modulation (PWM), an abbreviation of english "Pulse Width Modulation", is abbreviated as pulse width modulation, a very effective technique for controlling analog circuits using digital output of a microprocessor, and is widely used in many fields from measurement, communication to power control and conversion. Pulse width modulation is an analog control method that modulates the bias of the gate or base of a transistor according to the change of the corresponding load to realize the change of the on time of the output transistor or transistor of a switching regulator, and this method can keep the output voltage of the power supply constant when the operating condition changes, and is a very effective technique for controlling an analog circuit by using the digital output of a microprocessor. The PWM control technology has the advantages of simple control, flexibility and good dynamic response, and becomes the most widely used control mode of the power electronic technology, and is also a hot spot for people to study. Since the development of the current science and technology has no limit between disciplines, the combination of the modern control theory idea or the realization of the resonance-free soft switching technology will become one of the main directions of the development of the PWM control technology.

The principle of adjusting the color of the LED lamp through the LED power supply is as follows: based on the principle of three primary colors, the three primary colors of red, green and blue can be mixed to obtain most of colors in the nature, if each color of red, green and blue is divided into 256 gray scales, how to accurately control the gray scales of the three colors of red, green and blue to mix the required colors is critical, an integrated circuit can be additionally arranged in the lamp to achieve the purpose, and the gray scales of the three colors of red, green and blue can be accurately controlled in a pulse width modulation mode to realize color change.

The principle of adjusting the color temperature of the LED lamp through the LED power supply is as follows: at least 2 LEDs are arranged in the LED lamp, one is warm light (about 3000k color temperature), and the other is cold light (about positive white, 7000k color temperature). Each path is independent. By giving each path a different brightness, the adjustment of the color temperature and the adjustment of the brightness can be performed for the whole lamp. For example, if the color temperature of the light source is 3000k, the brightness is only 10% of the full brightness, and the brightness of the light source is only 40% of the full brightness, the color temperature of the light source mixed in the lamp body may be only 5000k, that is, the actual dimming and color mixing can be adjusted from the brightness and the color temperature (see the adjusting mode based on PWM in the prior art).

In practice, in order to generate a digital code signal for practical use in the control device, the LEDs are further provided with an adjusting device connected to the LED lamp body.

In order to enable the adjusting device to generate the digital code signal, an adjusting device for receiving the adjusting instruction for the LED lamp and a modulating device for modulating the adjusting instruction into the digital code signal are further arranged on the adjusting device. The adjustment instruction received by the adjustment device for the LED lamp is an electric signal generated by a user of the LED lamp by an action directly applied to the adjustment device, or data transmitted to the LED lamp by the mobile device.

In order to enable the adjustment device to receive actions applied by a user on the adjustment device, a knob, and/or a touch screen, and/or a voice pick-up device are provided on the adjustment device. The user generates instructions for the LED lamp by means of a rotation or pressing action of the knob, a point, a stroke operation of the touch screen, or a direct occurrence to the voice pick-up device, the specific instructions comprising a high-low adjustment of the brightness, the color temperature of the LED lamp, and a color change adjustment of the color. For the purpose of simplifying the connection of the internal circuit of the LED lamp, the adjusting device is connected with the LED lamp in a single-wire mode. I.e. the adjusting means are directly connected to the LED.

Optionally, as shown in fig. 2, in order to improve portability of the LED lamp with lighting parameter adjustment, the control device 1 may be further disposed inside the LED lamp body 2, so that the LED lamp 2 with lighting parameter adjustment function may be mounted on a normal desk lamp socket through the lamp cap 3 of the LED lamp, thereby effectively utilizing existing resources without manufacturing or purchasing new equipment for the LED lamp. For the purpose of improving the light-emitting softness of the LED lamp 2, a lampshade 4 may be further disposed at the front end of the LED lamp 2.

In order to further improve the color temperature adjustment of the LED lamp, a mechanical switch is further arranged on the power line where the LED lamp is located, and when the LED lamp is used, a user can adjust the color temperature of the LED lamp in a sectional mode by continuously pressing the mechanical switch.

For example, pressing the mechanical switch once adjusts the LED lamp to a first preset color temperature; pressing the mechanical switch for two times, and adjusting the LED lamp to a second preset color temperature; pressing the mechanical switch three times, adjusting the LED lamp to a third preset color temperature, and so on, after pressing the mechanical switch for many times, realizing the cyclic adjustment of the color temperature of the LED lamp.

The application provides an LED lamp with adjustable illumination parameters, which comprises an LED lamp body and a control device connected with the LED lamp body, wherein the control device comprises a rectifying circuit, a signal demodulation circuit, a signal processing circuit and an LED power supply, and a diode is arranged between the signal processing circuit and the LED power supply.

Compared with the prior art, the LED lamp has the advantage that the function of adjusting the illumination parameters can be realized by the common LED lamp.

31. and acquiring an adjusting instruction aiming at the LED lamp, and generating a digital coding signal according to the adjusting instruction.

32. And identifying and demodulating the digital coded signals to obtain a demodulated result.

33. Decoding according to the demodulated result, generating a PWM control signal according to the decoded result, and controlling the illumination parameters of the LED lamp according to the PWM control signal.

In practice, the process of adjusting the lighting parameters of the LED lamp will be described taking an actual usage scenario as an example.

The user determines a regulating instruction (for example, regulating the color temperature to 5000K) corresponding to the illumination parameter to be regulated according to the actual use requirement, and inputs the regulating instruction into the regulating device, so that the regulating device generates a digital coding signal according to the regulating instruction, and transmits the digital coding signal to the signal demodulation circuit. The digitally encoded signal is modulated for ease of transmission.

The signal demodulation circuit receives the digital code signal, recognizes and demodulates the digital code signal according to a pre-stored demodulation rule, and then sends the demodulated result to the signal processing circuit.

The signal processing circuit decodes according to the demodulated result to obtain the demodulated result (color temperature is adjusted to 5000K), and generates specific PWM control signals, such as specific adjustment frequency values and duty cycle information, according to the obtained result. And a specific PWM control signal is sent to the LED power supply, so that the LED power supply can adjust the power supply of the LED lamp according to the specific PWM control signal, and finally the color temperature of the LED lamp is regulated to 5000K.

The lighting parameters include at least one of brightness, color temperature, and color, and in actual use, the actual use requirements of the user may include adjusting one or more of brightness, color temperature, and color.

The digital coding signal is generated according to the actual use requirement, and then the digital coding signal is decoded and demodulated, so that the PWM control signal is finally obtained to adjust the power supply of the LED lamp, and the LED lamp is enabled to show the effect corresponding to the actual use requirement.
