Description
Technical field
Development of science and technology is maked rapid progress, and will popularize gradually based on the household electrical appliance of wireless power transmission technology and enter huge numbers of families.So-called " wireless power transmission " but be to utilize a kind of special installation to change the electric energy of power supply the energy of radio transmission into, again this energy is transformed back into electric energy at receiving terminal, thereby arrives the wireless power to electric equipment.
But the intelligent LED torch tube of the utility model---wireless charging belongs to contactless electric energy transmission technology in the brand-new application of civil area.It can eliminate the electric wire connection basis to the charging of LED flashlight, and the luminous host chipset of flashlight self is by constituting through the asymmetric LED matrix of arranging after engineering thermal design and the optimization, easy, the intelligent quick that charges has been realized the health idea of energy-conserving and environment-protective again on long-lived quality requirement.
Background technology
Tradition LED flashlight needs external socket to charge, even and the luminescence chip group of some LED flashlight is made of plurality of LEDs, but problem or thermal design defective because LED arranges, the heat that makes the luminescence chip group produce in the course of the work can not dissipate rapidly and gather, cause the LED flashlight easily aging, the life-span short, luminous flux can't satisfy lighting requirement.Concerning general public, on the basis that increases use cost, brought environmental pollution again.How to make resources effective utilization, remove the trouble of lead during charging from, increase an important topic that becomes the design of intelligent LED torch tube in brightness and useful life again.
Summary of the invention
Technical problem to be solved in the utility model is, on the basis of Based Intelligent Control, based on the wireless power transmission technology LED flashlight is carried out wireless charging, by the luminous host chipset of LED flashlight is carried out engineering thermal design and optimization, realize reliable service behaviour and highlight illumination, easy, the intelligent quick that charges, energy-conserving and environment-protective.
The technical solution adopted in the utility model is: by a rectification circuit 220V AC rectification is become galvanic stabilized voltage power supply, supply with emitter through lead, the receiving system embedded with flashlight carries out coupled resonance, via secondary rectifier bridge booster circuit, finally give luminous host chipset by throwing light on through the asymmetric LED matrix of arranging after engineering thermal design and the optimization again.
Luminous host chipset is by the asymmetric LED matrix of arranging after passing through the engineering thermal design and optimizing, reduce the spacing between adjacent two LEDs gradually from the luminous plaque center to both sides, thereby the heart temperature difference time, reduce the mean temperature of whole luminous plaque on the decrease, improve radiating efficiency.
Receiving system constitutes new antiresonant circuit by capacitor C 2 and inductance L 2, and they can realize the maximization wireless transmission of electric energy with the emitter impedance matching time.Become direct current through the secondary rectification boosting circuit and supply with flashlight.
The utility model can realize that short of electricity is charged automatically and full electricity automatically shuts down control to the LED flashlight when external sensing device.

Embodiment
Below in conjunction with example and accompanying drawing to the utility model--but the intelligent LED torch tube of wireless charging elaborates.
As shown in Figure 1, the alternating current of 220V is inserted D.C. regulated power supply, direct current through rectifying and voltage-stabilizing realization 50V is exported to emitter, in emitter, become ac voltage signal through high-frequency inversion, be loaded into the former limit of the loosely coupled transformer after the compensation, realize the resonance coupling with the receiving coil that is embedded in the LED flashlight, through the secondary rectification boosting circuit, the voltage of 220V is supplied with luminous host chipset by through the asymmetric LED matrix of arranging after engineering thermal design and the optimization, realize the high brightness of LED flashlight.
As shown in Figure 2, a rectifier bridge of being made up of 4 diodes is delivered in the step-down of 220V alternating current process transformer, passes through stable-pressure device again, is output as the direct current of 50V.
As shown in Figure 3, be that luminous host chipset is the LED matrix through the non-homogeneous arrangement mode of employing behind the optimizing thermal solution, reduce the spacing between adjacent two LEDs gradually from the luminous plaque center to both sides, thereby on the decrease the heart temperature difference time, reduce the mean temperature of whole luminous plaque, improve radiating efficiency.
As shown in Figure 4, constitute new antiresonant circuit by capacitor C 2 and inductance L 2, during with the emitter impedance matching, can realize the maximization wireless transmission of electric energy.Become direct current through the secondary rectification boosting circuit and supply with the LED flashlight.
As shown in Figure 5, be a secondary rectifier bridge booster circuit that is connected with receiving system.
The utility model can realize that short of electricity is charged automatically and full electricity automatically shuts down control to the LED flashlight when external sensing device.
