Description

Multi-functional LED desk lamp

(1) technical field

The present invention relates to the LED light fixture, particularly a kind of LED light fixture with myopia, amblyopia treatment function.

(2) technical background

Adolescent myopia is the disease that the accommodative excess anxiety causes, is called accommodative myopia again.The key of treatment is the regulative mechanism that is to improve eye, promptly improves the easypro function that contracts of ciliary muscle.Can use the treatment of after image method, utilize pupillary light reflex to bring out accommodation reflex cure etc.

The treatment of after image method is the method for a kind of traditional amblyopia, myopia; It is the after image that retina according to the people forms after by strong illumination; The inhibition that can be eyeground macular area (eye thing sensitizing range) obtains elimination in various degree; Training simultaneously improves the visual function of macular area central fovea, makes paracentral fixation progressively transfer central fixation to.Determined curative effect, remarkable is treated in after image ruling by law.

Utilize pupillary light reflex to bring out the accommodation reflex cure, this law is brought out the principle of accommodation reflex and the characteristic of the excited vision system of flicker ruddiness according to light reflex, and adopting with ruddiness is that main polychromatic light flicker is the method that stimulates accordance with physiology to require.

LED desk lamp function is simple now, has only illumination functions, not treatment myopia, amblyopia function; But its single LED luminosity is big, uses plurality of LEDs that illumination is provided, in conjunction with the method for above-mentioned treatment myopia, amblyopia; Improve control circuit, can make the LED desk lamp have treatment myopia, amblyopia function.

(3) summary of the invention

The present invention is the deficiency that overcomes the LED desk lamp, and a kind of LED desk lamp with treatment myopia, amblyopia function is provided.

The objective of the invention is to realize through following technical scheme:

Multi-functional LED desk lamp is by the LED desk lamp socket, and movable rod, base, LED control circuit are formed.Movable rod changes the LED desk lamp socket greater than 90 degree bendings between illumination and two kinds of duties of treatment eyesight.The LED desk lamp socket comprises: highlight illumination LED, high brightness flicker LED, red LED, color LED.Illumination LED---under Single-chip Controlling with the LED of lighting system work; Flicker LED---under the Single-chip Controlling with the LED of flashing mode work; Red LED---is sent the LED of red radiance: color LED---and is sent non-red color LED.Color LED with annular spread around red LED.

The LED control circuit comprises: single-chip microcomputer mu balanced circuit, single chip circuit, program storage, mode of operation selection key, power amplification circuit.The annexation of LED control circuit each several part is: the dc source of outside low-voltage is the entire circuit power supply; The single-chip microcomputer mu balanced circuit connects single chip circuit and exports 5 volts stable DC voltage; Single-chip microcomputer mu balanced circuit linker holder is also exported 5 volts stable DC voltage; Program storage is connected with single-chip data line, address wire; The output interface of single-chip microcomputer is connected with power amplification circuit, and power amplification circuit is connected with highlight illumination LED, high brightness flicker LED, red LED, color LED, and the mode of operation selection key is connected with single-chip microcomputer.The level signal power amplification circuit power of single-chip microcomputer output is amplified the corresponding LED of rear drive.Finally reach treatment myopia, amblyopia and illumination purposes.The dc source of outside low-voltage is to be lower than 24 volts dc source, and the CPU of LED control circuit is a single-chip microcomputer.

The operation principle of LED desk lamp is such; When normal illumination is used; Illumination LED provides light source as illumination LED: when realizing that after image ruling by law is treated, and rule flicker under the Single-chip Controlling of flicker LED in the LED control circuit; Reach treatment myopia, amblyopia function, other LED does not participate in work; When realizing utilizing pupillary light reflex to bring out the accommodation reflex cure, rule flicker under the control of red LED and the color LED single-chip microcomputer in the LED control circuit around it reaches treatment myopia, amblyopia function, and other LED does not participate in work.Because this desk lamp works in the open environment,, reach illumination and the effect of treating so each LED all is high brightness LEDs.

The invention has the beneficial effects as follows: multi-functional LED desk lamp not only can provide normal illumination, and after with kopiopia, multi-functional LED desk lamp can provide the service of treatment myopia, amblyopia easily for the user, achieve many things at one stroke.

(5) specific embodiment

Accompanying drawing 4 is that the circuit of LED control circuit is formed and the annexation block diagram, and accompanying drawing 5 is LED control circuit schematic diagrams, the concrete detailed description as follows:

Accompanying drawing 5 included circuit are: the dc source of outside low-voltage, positive 12 volts power supply are the entire circuit power supply.The single-chip microcomputer mu balanced circuit---form by U1, C1, C2.

Single chip circuit, program storage---form by U2, C3, C4, C5, Y1 and pull-up resistor Rs.Single-chip microcomputer uses the 89C51 type in this circuit, and there is the program storage of 2KB its inside, so the outside holder of not designing program separately again of single-chip microcomputer.

Power amplifier---by Q0, R0, Q1, R1, Q2, R2, Q3, R3, Q4, R4, Q5, R5, Q6, R6 form.

Flicker LED---form by D1, D2; Red LED---form color LED by D3---by D4, D5, D6, D7 and form illumination LED---by D6 to Dn (some abridged LED are arranged therebetween) with form; Power amplifier Q0 drives the flicker LED of D1, D2 formation in other words; Power amplifier Q1 drives the red LED that D3 forms, power amplifier Q3, Q4 by that analogy, Q5, Q6.Key switch S1 is the working forms selection key.

The course of work of LED control circuit:

After dc source 12 volt direct currents of outside low-voltage are circuit supply, after the voltage stabilizing through U1, C1, C2, obtain 5 volts dc source; Be single-chip microcomputer U2 power supply, single-chip microcomputer U2 is according to the program work in the program storage, for example: count 0x01 immediately at P1 delivery outlet output hexadecimal; Then P10 output high level draws driven effect pipe Q0 on the high level process resistance R s; Q0 conducting, 12 volts power supply are passed through current-limiting resistance R0, Q0, are D1, D2 power supply, D1, the luminous work of D2; P1 delivery outlet output hexadecimal is counted 0x00 immediately, P10 output low level then, and D1, D2 extinguish, and corresponding delay moves in circles, and desk lamp realizes that the after image method treats like this.

In like manner, when P1 output hexadecimal is counted 0x02 immediately, the luminous work of D3, color LED D4, D5, D6, the luminous successively work of D7 when P1 output hexadecimal is counted 0x04,0x08,0x10,0x20 immediately after 0.5 second at interval successively, and move in circles.When desk lamp was realized utilizing pupillary light reflex to bring out the accommodation reflex cure like this, rule flicker under the control of red LED and the color LED single-chip microcomputer in the LED control circuit around it reached treatment myopia, amblyopia function.Color LED is distributed in annular arrangement form around the red LED, can be 4,6,8.When P1 output hexadecimal was counted 0XFF immediately, all LED lighted, and desk lamp is realized illumination functions.

Below be the program of the C language used of the present invention:
