Description

Title of Invention: A Microcomputer-Controlled Intelligent Lighting Switching LED Lantern Technical Field

[0001] The present application relates to the field of LED lamps, and in particular, to a microcomputer-controlled intelligent lighting switching LED lantern.

BACKGROUND OF THE INVENTION

[0003] Existing LED lights, usually using a constant current drive system, are prone to flash frequencies, and there is no problem in an atmosphere such as a KTV or a stage set, or even an atmosphere effect. However, if applied to home life, the flash frequency has a great influence on the vision, so that the LED lights cannot be applied to the home life lighting.

[0004] In addition, existing LED lights with multiple color switching usually require one color for each color to control, or color control on a smart phone or an intelligent controller, which is extremely inconvenient for home use. More importantly, LED lanterns are usually made of red, green and blue monochromatic LED beads, which are mixed in different ratios to obtain various colors. However, the combination of red, green and blue monochromatic LED beads is not efficient, so it is mainly used for ambience viewing and cannot replace traditional white lighting, which greatly limits the home use of LED lights. With the improvement of living standards, people's requirements for quality of life are getting higher and higher. Traditional white light or warm white lighting can't provide color light atmosphere; and LED lights can't replace traditional white or warm white light; therefore In the case of occasionally needing a light-colored atmosphere, if an LED lantern is installed separately, it is neither economical nor extremely wasteful of resources, which is why LED lanterns are difficult to use at home.

[0005] Utility model content

[0006] It is an object of the present application to provide a micro-computer controlled intelligent light switching LED lantern with improved structure.

In order to achieve the above object, the present application adopts the following technical solutions.

[0008] This application discloses a microcomputer-controlled intelligent lighting switching LED lantern, including a power supply, a capacitor power supply system, a microprocessor, an LED driving circuit controller and an LED lamp; the power supply controls the entire intelligent dimming The power of the LED light is turned on or off; the capacitor power supply system is connected to the power supply and coupled to the microprocessor, and provides a short power supply to the microprocessor after the power is turned off; the microprocessor is powered by the power supply. The number of presses, the signal is modulated into a 20K-70K signal is sent to the LED driver circuit controller, and the LE D lamp is controlled to switch the color or color temperature. Specifically, after the power switch is turned off, the capacitor power supply system continues. In the daytime of power supply, the power supply is turned on again, and it is regarded as one press, and the color or color temperature is switched; the LED drive circuit controller is a constant voltage driver, and a capacitor is connected to the output end of the constant voltage driver, and the capacitor makes the output waveform Smooth, let the LED lights do not strobe; LED lamps control the LED lamp bead to emit light according to the signal transmitted by the LED driver circuit controller, to change the color or color temperature.

[0009] It should be noted that the microcomputer-controlled intelligent light switching LED lantern of the present application uses a constant voltage driver, and a capacitor is connected to the output end of the constant voltage driver, so that the LED lantern does not strobe under the naked eye; Can meet the needs of home life use.

[0010] It should also be noted that the microcomputer-controlled intelligent light switching LED lantern of the present application has a built-in capacitor with a large capacitance value, that is, a capacitor power supply system, and the capacitor can also provide intelligent lighting after the power is turned off. The circuit of the control part, that is, the microprocessor, is powered for a period of time, usually set to about 5 seconds, so after the power is turned off, the circuit of the actual intelligent control system is still running, so the intelligent control system can obtain the power. In the state of the switch, the power is turned on once, and the color temperature or color is switched. When the power is turned off for more than 5 seconds, it is considered to have been powered off, and the current color temperature/color state is saved. The next time the xenon lamp is the color of the previous turn off.

[0011] Preferably, the LED lamp bead comprises a red monochromatic lamp bead, a green monochromatic lamp bead, a blue monochromatic lamp bead, a white monochromatic lamp bead and a warm white monochromatic lamp bead, and a total of five sets of monochromatic lamp beads composition.

[0012] It should be noted that the LED lantern of the present application creatively introduces two light groups of white light monochromatic lamp beads and warm white light monochromatic lamp beads, and white light or white light is directly used in white light or white light. Lamp beads or warm white monochromatic lamp beads can be used for illumination, avoiding the problem that the three monochromatic LED lamp beads of red, green and blue are not efficient in mixing white light, so that the LED lights can be directly used for home lighting. It can meet the occasional demand for colored light. The LED lantern of the present application separately uses a set of white light monochromatic lamp beads and a set of warm white monochromatic lamp beads, so that the LED lights have illumination function, avoiding red, green and blue three kinds of monochromatic LED lamp beads mixed white light. The problem of low efficiency has expanded the application range of LED full-color lights and opened up the home application market for LED lights. Compared with the LED full-color lights on the market, the LED full-color lights on the market are basically three-in-one RGB full-color lamp beads, and this application uses a single color lamp bead to combine various colors. .

[0013] Preferably, the microprocessor transmits a signal modulated to 65K to the LED driver circuit controller.

[0014] Preferably, the LED lamp presets five colors or color temperature states, respectively, warm yellow light, white light, warm white light, color light conversion, fixed color light; the microprocessor is pressed in five colors according to the number of times the power is turned off. Color temperature Switch between states.

[0015] It should be noted that the LED color light of the present application presets five colors or color temperature states for convenient use, wherein the warm yellow light is formed by mixing different ratios of white light and warm white light according to different proportions. The red, green and blue are mixed according to different proportions. The color light conversion refers to changing the proportion of red, green and blue continuously or changing the proportion of red, green and blue according to a certain law to gradually change the color light. The effect of the fixed color light is to press the power switch once during the gradual change of the color light, so that the color light is fixed in the current state without conversion. Of course, it can be understood that if there is no white light monochromatic lamp bead and warm white light monochromatic lamp bead warm yellow light can also be mixed by red, green and blue according to different proportions, and red, green and blue can also be mixed into white light and Warm white light, but the efficiency is relatively low.

[0016] The beneficial effects of the application are:

[0017] The microcomputer controlled intelligent LED lantern of the present application adopts a constant voltage driver, and a capacitor is connected to the output end of the constant voltage driver, and cooperates with the modulated 20K-70K signal, so that the LED lantern is not observed by the naked eye. Strobe, solves the problem of serious strobe of LED lights. Moreover, the color or color temperature can be switched directly by pressing the power switch, which is simple and convenient to use, and lays a foundation for the application of LED lights with multiple colors or color temperature switches to the home life.

DETAILED DESCRIPTION

The present application is further described in detail below with reference to the accompanying drawings.

[0027] Example

[0028] The microcomputer-controlled intelligent light switching LED color lamp of this example, as shown in FIG. 2, includes a power supply switch, a capacitor power supply system, a microprocessor, an LED drive circuit controller, and an LED lamp; the power supply controls the entire smart The power supply of the dimming LED lamp is turned on or off; the capacitor power supply system is connected to the power supply and coupled to the microprocessor, and provides a short-term power supply to the microprocessor after the power supply is turned off; The number of times of pressing, the signal is modulated into a signal of 20K-70K and transmitted to the LED driving circuit controller to control the color or color temperature switching of the LED lamp. Specifically, after the power supply is turned off, during the continuous supply of the capacitor power supply system Inside, once again, the power is turned off, as a single press, color or color temperature switching; L ED drive circuit controller is a constant voltage driver, and a capacitor is connected to the output of the constant voltage driver, the capacitor smoothes the output waveform, let LED lights do not have stroboscopic light; LED lamps control the LED lamp bead to emit light according to the signal transmitted by the LED driver circuit controller Color or color temperature changes.

[0029] In this example, the LED color lamp comprises a bracket and an LED lamp bead mounted on the bracket, and the LED lamp bead is composed of a red light monochromatic lamp bead, a green monochromatic lamp bead, a blue monochromatic lamp bead, and a white light monochrome lamp. Beads and warm white monochromatic lamp beads, composed of five sets of monochromatic lamp beads. Among them, the white light monochromatic lamp beads emit white light, the warm white light monochromatic lamp beads warm white light, white light and warm white light can be red light monochrome lamp beads, green light monochrome lamp beads, blue light monochrome lamp beads are arranged in different proportions. It is only less efficient. Therefore, this example uses white light monochromatic lamp beads to emit white light, and warm white light monochromatic lamp beads to warm white light. The arrangement of five sets of monochromatic lamp beads is shown in Figure 4. In addition, Figure 5 shows the arrangement of another five sets of monochromatic lamp beads, which can also achieve white or warm white lighting effects. It can be understood that this example uses five sets of monochromatic lamp beads to form an LED full-color lamp capable of daily illumination. The specific arrangement of the five sets of monochromatic lamp beads can be changed according to different designs, not limited to Figure 4 and Figure 5 Kind.

[0030] This example specifically uses 6000K white light monochromatic lamp beads, and 3000K warm white light monochromatic lamp beads to achieve daily high color rendering index illumination, and by controlling the proportion of white light monochromatic lamp beads and warm white monochromatic lamp beads , can also get a wide color temperature range, 2700K-6500K, white illumination source, achieving a higher color rendering index. By controlling the proportion of red, green and blue light beads, you can get rich colors and intelligent scenes. In this example, the LED lights use red, green and blue three-color LED lamp beads to achieve full-color ambient lighting, that is, To meet the needs of users' lighting, but also to take into account the atmosphere effect of colored lights, a multi-purpose.

[0031] The LED driving circuit controller of this example adopts a constant voltage driving mode, and adopts the 65 K intelligent PWM control signal invented in this example to solve the stroboscopic problem existing in the current market. The LED constant voltage driver is mainly responsible for amplifying the signal of the control lamp emitted by the microcomputer processor to drive the LED lamp bead array J |J to achieve different lighting effects. The principle of the LED constant voltage driver in this example is shown in Figure 1. After receiving the signal of the 65K control lamp from the microprocessor, the LED constant voltage driver directly amplifies the signal voltage to the lamp bead array. In this example, the constant voltage driver The output is connected to a capacitor, and the 65K lamp control signal output from the microcomputer processor can make the LED array achieve a very good effect without stroboscopic. As shown in Figure 1, the waveform input in this example is the waveform a with higher frequency. The output waveform b will be smoother after passing through the capacitor, so that the LED will not flash. In this example, the control signal output by the microprocessor is at 20K- Within 70K, no stroboscopic can be achieved.

[0032] The intelligent light switching LED lantern in this example, the LED lamp presets five colors or color temperature states, respectively, warm yellow light, white light, warm white light, color light conversion, fixed color light; the control system is based on the power supply The number of presses is switched in five color or color temperature states. Among them, the warm yellow light is made up of white light and warm white light according to different proportions. The color light is mixed by red, green and blue according to different proportions. The color light conversion means non-stop change of red, green and blue. The ratio of the three or the ratio of red, green and blue according to a certain law reaches the effect of gradually changing the color light, while the fixed color light presses the power supply during the process of gradually changing the color light, so that the color light is fixed at Current state, no transformation. Specifically, this example uses 6000K white monochromatic lamp beads, and 3000K warm white monochromatic lamp beads to achieve daily high color rendering index illumination, while warm yellow light controls white monochromatic lamp beads and warm white monochromatic lamp beads. Matching, obtained 3000K warm yellow light. As shown in Figure 3, the five colors or color temperature states of this example are set in order. The specific method of pressing the power to control the color or color temperature is as follows:

[0033] State 1: When the power is turned on, the light is on, and the color/color temperature of the light is the same as the color/color temperature of the last time the light is turned off.

[0034] State 2: Adjust the color or color temperature, press the power switch to turn off the power, that is, close the power switch, turn off the power for 5 seconds, press the power switch to turn on the power, then the power is turned off, and the light is off. That is to say, when the off-off light is off and then on, it will switch to another color/color temperature; then, turn off the light off, then close the switch, and switch to the next color/color temperature; Five color temperatures/colors can be switched, cycled, It is 1234512345... This is the color or color temperature of the cycle. If you choose the color temperature you like, you don't need to turn it off. This color temperature/color is always on.

[0035] In FIG. 2, the fourth color temperature change is specifically, when the switch is adjusted to the fourth gear RGB transform, the red and green are started.

, blue color change, this is the full color cycle change, when changing to the personal favorite color 吋, turn off the 再 off and close the 一次 once, then enter the 5th gear, it will stop changing, stop the color selected by the individual on

. This will select any of the 160,000 colors that are combined with red, green and blue.

[0036] State 3: Turn off the light, as mentioned in State 2, if the power is turned off within 5 seconds after turning off the power, it will change to the next color or color temperature, and then turn off the power after 5 seconds after turning off the power. When the power is turned off, the power is turned off within 5 seconds after the power is turned off. The system will consider that the light has been turned off, thus saving the current color temperature/color. The next time the power is turned off, the color temperature saved this time is automatically displayed. colour.

[0037] It should be noted that the five transformations in FIG. 3 are only a preset manner of the present example, and the smart lamps of the present application are not limited to the five color temperature/color variations; in fact, according to different usage requirements, You can get more preset functions such as dimming and color adjustment.

The above is only a preferred embodiment of the present application, and is not intended to limit the technical scope of the present application. Those skilled in the art, in light of the technical solutions, may make some modifications and modifications, which are in accordance with the present technology. Any modifications, equivalent changes and modifications made to the above embodiments are still within the scope of the technical solutions of the present application.
