Description

The intelligent LED searchlight of wireless power

Technical field

Along with development of science and technology and innovation, the electric equipment technological based on wireless power transmission will get into 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 wireless power electric equipment.

The intelligent LED searchlight of the utility model---wireless power belongs to brand-new, the high-end applications field of contactless electric energy transmission technology.It can eliminated on the electric wire connection basis to the power supply of LED searchlight; And the luminous host chipset of searchlight self is by constituting through the asymmetric LED matrix of arranging after engineering thermal design and the optimization; Simple installation, intelligence have realized the health idea of energy-conserving and environment-protective again flexibly on long-lived quality requirement.

Background technology

The tradition searchlight needs external wire to supply power; Even some large-scale searchlight itself is made up of the LED of many certain power at present; But because LED arranges or the thermal design defective; Make LED produce heat in the course of the work and can not dissipate rapidly and gather, thus cause the LED searchlight be prone to aging, the life-span is short, luminous flux can't satisfy the desired standard near 1000 lumens of general illumination.Concerning operator, on the basis that increases maintenance cost, brought potential safety hazard again.How on the efficient basis that utilizes of electric energy, remove lead from, increase brightness and become an important topic of intelligent LED searchlight design useful life.

Summary of the invention

The utility model technical problem to be solved is; On the basis of Based Intelligent Control, based on the wireless power transmission technology LED searchlight is carried out wireless power, through the luminous host chipset of LED searchlight is carried out engineering thermal design and optimization; Realize reliable operating characteristics and highlight illumination; Simple installation, with low cost, energy-conserving and environment-protective.

The technical scheme that the utility model adopts is: D.C. regulated power supply (2) (rectification circuit is housed a time); Emitter (3); LED searchlight (luminous host chipset is by the asymmetric LED matrix (4) of arranging after passing through the engineering thermal design and optimizing, embedded receiving system (5) and secondary rectifier bridge booster circuit (6)).

Emitter (3) comprises two MOSFET, and they can alternate conduction, is that the LC resonant circuit of back is created alternating current; C1 is a resonant capacitance, and L1 is a resonant inductance, and their parallel resonances to be improving tranmitting frequency, thereby electric energy is sent to receiving terminal with the form of frequency electromagnetic waves.

Luminous host chipset is by the asymmetric LED matrix (4) of arranging after passing through the engineering thermal design and optimizing; Reduce the spacing between adjacent two LEDs from the light fixture center gradually to both sides; Thereby the heart temperature difference time, reduce the mean temperature of whole lamp on the decrease, improve radiating efficiency.

Receiving system (5) 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 secondary rectification boosting circuit (6) and supply with searchlight.

The utility model need use common 220V mains lighting supply, when external photo resistance sensing device, can realize control automatically to the LED searchlight.
