Description

Technical Field

[0001] The present application relates to the technical field of LED lamp control, and in particular to an intelligent portable eye protection lighting circuit. Background Art

[0002] The latest research data shows that fluorescent lamps can easily cause myopia in children. This is because the cold fluorescent light produced by fluorescent lamps has a gray-blue hue. Under this light, the text and patterns on the books lack clear outlines, which can easily cause readers' eyes to fatigue. Over time, it can induce myopia or deepen myopia. The light source of incandescent lamps is a heating filament, which emits constant light. It does not have the flickering and electromagnetic pollution of fluorescent lamps, and is a healthy light for learning.

[0003] Existing learning lighting uses LED desk lamps, which are blue light chips that emit light and are colored by fluorescent powder. There is only one or two LED light sources, which are too different from the spectrum of natural light to achieve a truly healthy eye protection spectrum. It is easy to cause visual fatigue, has poor eye protection effect, and cannot truly prevent myopia effectively.

[0004] Furthermore, current students often need to use mobile phones to complete their homework, and the spectrum of mobile phone light source is very different from the spectrum of natural light, which seriously affects eye vision. Summary of the invention

[0038] The light source combination circuit 1 is effectively combined with a variety of LED light sources to achieve constant current drive. The main light source and four groups of selected light sources are used. According to the needs of use, the function selection circuit 2 is used to perform different spectrum compositions to achieve different lighting function selections, and a continuous spectrum that is beneficial to vision protection is achieved by using multiple light sources. The main light source is a healthy light source for the human body, which can promote blood circulation and is beneficial to metabolism. It is composed of two different wavelengths of a first wavelength red light source group and a second wavelength red light source group connected in series. The red light RL1-RL16 of the first wavelength red light source group is connected in parallel, which is a 690 wavelength red light, which is beneficial to improving the elasticity of blood vessels; the red light RM1-RM16 of the second wavelength red light source group is connected in parallel, which is a 660 wavelength red light, which is beneficial to improving the photosensitivity of visual cells.

[0039] Function selection circuit 22, and spectrum combination circuit 1, realize 4 kinds of lighting function spectrum combinations. It is composed of touch switch SW2, control chip U5, N-channel MOS tube Q7-Q10, N-channel triode Q11, diode D9-D20, indicator LED LD3-LD5, resistors R31, R32, R36-R42, R45-R48, and capacitor C22. The working principle of chip U5 is that in the power-on standby OFF state, press SW2, A outputs high level, and the others are low level; then press -B to output high level, and the others are low level; then press -C to output high level, and the others are low level. It realizes the selection of different corresponding lighting spectra that are beneficial to students' eyesight protection, eyesight recovery, visual fatigue, and protection from mobile phone light source hazards.

[0040] Cycle mode: OFF->A->B->C->OFF->A->B->C->OFF.

[0041] When U5 is in the off state, Q11 is turned off, D12-D15 is turned on, MOS tubes Q7-Q10 are turned on, and all light sources work to achieve a lighting spectrum combination. The indicator light is off, indicating a lighting state.

[0042] The first one: press SW2, U5's A pin is high level, Q11 is turned on, D16, D20 are turned on, Q7, Q10 are turned on, the third wavelength red light source group, the second color temperature yellow light source group is selected, the main light source works, LD3 is on, indicating a lighting state.

[0044] The third type: press SW2, the C pin of U5 is high level, Q11 is turned on, D16, D17 are turned on, Q7, Q9, Q10 are turned on, the third wavelength red light source group, the fourth wavelength green light source group, and the main light source are working, and LD5 is on, indicating a lighting state.

[0045] Fourth: Press SW2 U5 off state, cycle in sequence. Resistors R45-R48 play a role in current balancing for the four groups of selected light sources.

[0046] Driving circuit 3, ordinary dimmable constant current boost driving circuit 3, working voltage 3.6-24V, external MOS, constant current feedback voltage 0.25V.

[0047] The dimming control circuit 4 adjusts the output current of the driving circuit 3 to realize four kinds of driving currents. The working principle of IC U4 is the same as that of chip U5. By pressing button SW3, different states of U4 are selected. By using different voltage divisions of R18, R19, R20 and R23, different current driving is realized, thereby realizing different brightness non-stroboscopic dimming requirements.

[0048] The emergency switching circuit 5 realizes the switching between the charger 5V and the battery boost 5V power supply, and realizes the priority use of the charger power supply 9. Prevent voltage error, current backflow, and damage to the charger and power bank circuit 6. It is composed of P-channel MOS tubes Q21, Q22, transistors Q24, Q26, Q27, resistors R51, R53, R54, R59-R63, and capacitor C31. In the process of battery power supply, once the input charger has power (5V), the resistor R62 is greater than 0.7V through the resistor R63 voltage divider, the N-channel Q27 is turned on, the resistor R60 voltage drops to 0, the transistor Q26 is turned off, and the P-channel MOS tube Q22 works in a diode state, the S pole voltage is 4.5V, and the driving circuit 33 works at a voltage of 4.5V. After a certain period of time, the resistor R53 charges the capacitor C31 (0.1uF), the voltage across the resistor R54 reaches 0.7V, the N-channel transistor Q24 is turned on, the transistor Q21 is turned on, and the operating voltage of the drive circuit 33 is 5V, which improves efficiency. The D pole of the emergency switching circuit is connected to the Type C charging port.

[0049] The output voltage of the switching circuit, that is, the voltage of the S pole of the P-channel MOS tube Q22, is supplied for lighting. Only when the light is turned on and the battery power is used, the P-channel MOS tube Q22 is turned on, thereby improving the utilization rate of the battery power. This protects the mobile phone charger and the battery charging circuit and improves the utilization rate of the battery power.

[0050] The power bank circuit 6 is a commonly used power bank circuit 6 controlled by IP5306IC. It can directly charge mobile phones and other devices and has a charging reminder function.

[0051] The switch control circuit 7 is composed of a button SW1, a switch chip U2, a P-channel MOS tube Q1, an N-channel triode Q2, a diode D1, and resistors R7-R9. The switch core U2 is a power consumption IC, which is directly powered by a battery. The working principle of the switch chip U2 is that P2 is at a low level in the power-on standby state, and is in the light-off state; press SW1, P2 outputs a high level to turn on the light; press again, P2 outputs a low level to turn off the light; press again -P2 outputs a high level to turn on the light; and the cycle repeats. In the light-on process, when the P2 pin of U2 is at a high level, the voltage of R8 through R7 is greater than 0.7V, the N-channel Q2 is turned on, and the G pole of Q1 is at a low voltage, then Q1 is turned on, driving the start 3 and related control circuits to work, on the contrary, when P2 is at a low level, Q1 is turned off, and the related circuits do not work. The diode D1 is used to reduce the supply voltage of the control IC U4 and U5, so that it can work at 4.5V to prevent the IC from being damaged. In case of emergency and charging, simple switch function is realized.

[0052] The emergency dimming circuit 88 is composed of an N-channel MOS tube Q6, resistors R27, R28, and current sampling resistors R13 and R12. When the input charger has power (5V), the voltage of R27 through R28 is greater than 2.0V, the N-channel Q6MOS tube is turned on, and the drive current is sampled in parallel through R13 and R12, and the drive current becomes larger, and the current I=0.25 / R13\\R12. When the input charger is out of power, the N-channel MOS tube Q6 is turned off, and the drive current is sampled through R12, and the current becomes smaller, and the current I=0.25 / R12. Here, only the sampling current is reduced. If a lower dimming is required, the input line is directly unplugged, and the dimming circuit is used to achieve more brightness adjustment through the button SW3. The emergency sampling current is adjusted to increase the dimming range.

[0053] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
