[0002] In some events, various decorations are usually used to decorate the scene. The decorations usually include decorative lights, which are generally controlled by LED decorative lighting. The LED decorative lighting is usually in three colors, namely red, green and blue.

[0003] Since LED decorative lighting is only available in red, green and blue, when white light is needed, red, green and blue are usually mixed to obtain white light. Due to the limitation of LED production process, there will be obvious color difference when RGB is mixed with white light during mass production, and the consistency of light is difficult to control. In addition, the brightness of RGB mixed white light is relatively low, about half of that of white LED. In order to meet the brightness and chromaticity requirements of white light, a group of white LED lamps is added, and four channels of data, R, G, B, and W (white), are generated respectively to control the LED light. However, the PC display system processes colors in RGB, and adding a W channel requires additional real-time signal processing, resulting in a huge amount of data when collecting signals in real time. It is also difficult for customers to handle changes in the effects of non-real-time collection, and large amounts of data processing will lead to resource consumption, so there is still room for improvement.

[0017] The embodiment of the present invention provides a resource-saving, energy-saving and environmentally friendly LED lamp, which solves the technical problem of resource consumption.

[0018] In order to enable those skilled in the art to better understand the scheme of the present invention, the technical scheme in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings 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.

[0019] Example 1

[0020] See also Figure 1 , Figure 1The present invention is a circuit connection diagram of an LED lamp, wherein the LED lamp comprises: a plurality of receiving ends of predetermined signals, a signal conversion module, a plurality of primary color modules and a white light module; the receiving ends of the plurality of predetermined signals are connected one-to-one with the input ends of the plurality of primary color modules, and the receiving ends of the plurality of predetermined signals are used to receive luminous signals for driving the primary color modules to emit light; the input end of the signal conversion module is respectively connected one-to-one with the receiving ends of the plurality of predetermined signals, and is also connected one-to-one with the input ends of the plurality of primary color modules, and the output end is connected with the white light module, and the signal conversion module is used to drive the corresponding primary color modules to emit light according to the luminous signals, wherein when the receiving ends of the plurality of predetermined signals all receive the luminous signals, the signal conversion module drives the white light module to emit light, and the plurality of primary color modules do not emit light.

[0021] It should be noted that when the white light module emits light, the primary color modules do not emit light.

[0022] Specifically, some of the predetermined signals include: a red light signal, a green light signal and a blue light signal, and some of the primary color modules include: an R light-emitting module, a G light-emitting module and a B light-emitting module, and the input ends of the R light-emitting module, the G light-emitting module and the B light-emitting module are respectively connected to the receiving ends of the red light signal, the green light signal and the blue light signal in a one-to-one correspondence.

[0023] Specifically, the signal conversion module includes an AND gate module, several input ends of the AND gate module are correspondingly connected to the receiving ends of several predetermined signals, and the output end of the AND gate module is electrically connected to the white light module, wherein when the output of the AND gate module is true, the white light module is lit.

[0024] Specifically, the AND gate module includes a plurality of first diodes, and cathodes of the plurality of first diodes are connected to receiving ends of a plurality of predetermined signals in a one-to-one correspondence.

[0025] It should be noted that each second diode is connected to a receiving end of a predetermined signal in a one-to-one correspondence.

[0026] Specifically, the white light module includes a light-emitting LED lamp LW, a switching device, a resistor R4 and a resistor RW; the positive pole of the LED lamp LW is connected to the power supply, and the negative pole is connected to the first end of the resistor RW; the second end of the resistor RW is connected to the output end of the switching device; the negative poles of the first diodes correspond one-to-one to the receiving ends of the predetermined signals.

[0027] It is understandable that the switch device can be a triode, a MOS tube, a photoelectric coupling device, a relay, etc. It should be noted that the number of the first diodes is consistent with the number of primary color light-emitting modules. For the type of the first diode, those skilled in the art can select it according to the actual needs of the circuit, and it is not limited here.

[0028] Specifically, the conversion module further includes: a plurality of second diodes; anodes of the plurality of second diodes are connected to a plurality of diodes in a one-to-one correspondence, and cathodes are connected to the output end of the switching device.

[0029] Specifically, the primary color module includes several light-emitting LED lamps and several switching transistors; the light colors of the light-emitting LED are the three primary colors of red, green and blue; the bases of the several switching transistors are connected one by one with the receiving ends of several predetermined signals, and the collectors are connected with the negative poles of the light-emitting LED lamps.

[0030] It can be understood that when the primary color modules are R light-emitting module, G light-emitting module and B light-emitting module, the R light-emitting module can include transistor QR, resistor R1, resistor RR and light-emitting LED lamp, and the signal conversion module can be: the first end of resistor R1 is connected to the RIN end and diode D1 in the receiving end of the predetermined signal, and the second end is connected to the base of transistor QR; the collector of transistor QR is connected to the first end of resistor RR, and the emitter is grounded; the second end of resistor RR is connected to the red light-emitting LED lamp, the base of transistor QR is also connected to the positive electrode of diode D6, and the negative electrode of diode D6 is connected to the collector of transistor Q1. The circuit of G light-emitting module is consistent with the principle and connection of R light-emitting module, and further specific connections can be referred to. Figure 1 It should be noted that the anodes of diodes D1, D2 and D3 are all connected to the base of transistor Q1, and the cathodes of diodes D4, D5 and D6 are all connected to the collector of transistor Q1.

[0031] According to the connection of the above circuit in this embodiment, when any of the output terminals RIN, GIN and BIN of the target light signal input module outputs a low-level light signal, Q1 is not turned on, the light LW is not lit, RGB is not affected by Q1, and the corresponding module will emit light according to the light signals of IN, GIN and BIN. For example, when the RIN terminal and the BIN terminal receive a light signal, the corresponding red light-emitting LED light and the blue light-emitting LED light will emit red light and blue light respectively, while the green light-emitting LED corresponding to the GIN terminal will not emit light. When the RGB inputs are all high-level light signals, Q1 is turned on and LW is lit, and the base current of the transistor GR, the transistor QG, and the transistor QB is pulled down through D4, D5 and D6, so that the transistor GR, the transistor QG, and the transistor QB are not turned on. At this time, the LED light LRGB is not lit, and the LW light in the white light module will emit white light. There is no need to add an additional set of white LED lights, thereby avoiding the huge amount of data when collecting signals in real time due to the additional signal processing of the PC display system.

[0032] Specifically, the plurality of switch transistors are all NPN transistors.

[0033] It is understandable that when the required white light brightness is higher, the brightness of the light mixed by the three primary colors is lower. Through the above method, when the three primary colors of light module receives a light emitting signal, the signal is converted to the white light module through the light conversion module to light up the white light module, thereby achieving high-intensity white light, so that there is no need to mix the light through the three primary colors of light modules, and only one module of the lamp needs to be lit, thereby reducing the power loss during light emission.

[0034] In this embodiment, by inputting a luminous signal for receiving a driving primary color module to emit light into a predetermined signal receiving end, the corresponding primary color module emits light as usual, and the input end of the signal conversion module is respectively connected to the receiving ends of several predetermined signals in a one-to-one correspondence, and is also connected to the input ends of several primary color modules in a one-to-one correspondence, and the output end is connected to the white light module. When the receiving ends of several predetermined signals all receive the luminous signal, the conversion module converts the luminous signal originally driving the primary color module into a luminous signal driving the white light module, so that the white light module is driven to emit light, while the primary color module does not emit light, and the white light emitted by the white light module replaces the white light mixed by several primary color light-emitting modules, so that the brightness of the white light is greater than the brightness of the mixed light, and there is no color difference, so as to meet the brightness and chromaticity requirements of the white light, and there is no need to light up all the primary color modules to mix the white light, and there is no need to add a one-W channel, and only the white light module needs to be lit, which reduces the power of the circuit when emitting white light, and is energy-saving and environmentally friendly. At the same time, the white light module and the primary color module use the same luminous signal to control the light emission, and there is no need to add a one-W channel, so that there is no need to process a large amount of real-time data, saving data processing resources. The technical problem of resource consumption has been solved.

[0035] See also Figure 2 , Figure 2 This is a circuit connection diagram of Example 2 of an LED lamp in the present invention. Example 2 is further described based on Example 1:

[0037] The signal receiving terminals RIN, GIN and BIN are respectively connected to the positive electrodes of the diodes D7, D8 and D9 in the signal conversion module, the negative electrodes of D7, D8 and D9 are connected to the emitter of the transistor Q2, the positive electrodes of the diodes D10, D11 and D12 are connected to one end of the lamp LRGB1 of the primary color module, and the negative electrodes are connected to the base of the transistor Q2, the other end of the lamp LRGB1 is connected to the collector of the transistor Q1, the base of the transistor Q1 is connected to the base of the transistor Q3 and the collector of the transistor Q2, the transistor Q3 is electrically connected to the lamp LW1, for the connection of its auxiliary components, please refer to Figure 2 .

[0038] In this embodiment, when the input is a common RGB common anode signal, and there is a voltage difference between any two groups of the signal receiving ends RIN, GIN and BIN, Q2 is turned on, Q1 is also turned on, and the lamps corresponding to RIN, GIN and BIN are illuminated. When the RGB inputs are all the same signal, Q2 is turned on and off, Q1 is also turned off, Q3 is turned on, and the lamp LW1 is illuminated.

[0039] Example 3

[0040] See also Figure 3 , Figure 3 This is a circuit connection diagram of Example 3 of an LED lamp in the present invention. Example 3 is further described based on Example 1:

[0041] An LED lamp comprises a signal control input module, a signal conversion module, a primary color module and a white light module; the signal control input module is connected to the input end of the signal conversion module for inputting a light emitting control signal; the output ends of the signal conversion module are both connected to the primary color module and the white light module, and the signal conversion module is used to convert the input signal input to the white light module or the primary color module according to the light emitting control signal input by the signal control input module.

[0042] See also Figure 3The signal input module includes a pixel control chip U1, which is used to convert the received light control signal into a PWM signal for controlling the brightness of each LED lamp in the primary color module, and input it into the signal conversion module. The three diodes D2, D3, and D4 in the signal conversion module form an OR gate. The transistor Q2 and the 12V voltage regulator form a comparator, so that the base voltage of the transistor Q2 is defined as a high level when it is higher than 12.7V. At the same time, the transistor Q2 performs the work of a NOT gate, so that the high level of the base is reversed. When any of the three signals is high (not bright), Q2 outputs a low level to the base of Q1 to turn on Q1, and at this time Q3 is not turned on, and the LED lights in the white light module are not bright. At this time, L1 to L6 are powered, so that L1 to L6 are lit. When the three signals are all low (bright), Q2 is not turned on, Q1 is not turned on, and L1 to L6 are not powered on. At this time, Q3 is turned on, the white light module is lit, and the primary color module does not emit light. For details on the connection relationship between each component, please refer to Figure 3 , which will not be described one by one here.
