Description

The lamp of LED under water of wireless power

Technical field

The present invention relates to a kind of lamp of LED under water, a kind of lamp of LED under water that adopts wireless power.

Background technology

The existing lamp of LED under water exists following deficiency:

At first, all be wired power supply, because the existence of lead is unavoidably pullled in the use, lead is damaged easily, causes electric leakage, and the lighter damages the LED lamp, and weight person gets an electric shock the people, jeopardize personal safety; Secondly, lamp is worked in water owing to expand with heat and contract with cold, and water can infiltrate in the lamp from the slit of the rubber of lead and light fixture, causes the interior short circuit of lamp; The 3rd, the LED lamp itself is thermal source, and the low amounts of water in the lamp can be evaporated, attached to the glass of lampshade, the atomizing of interior surfaces of glass ponding has a strong impact on luminous quantity and illumination effect.

To the improved wireless power of above phenomenon under water the LED lamp can avoid these problems comprehensively, thinking is following:

Summary of the invention

A kind of lamp of LED under water that adopts wireless power, it is made up of the colloid lampshade of an electric energy receiver, a heat-radiating substrate, one group of LED and a waterproof, and LED is fixed on the central authorities of heat-radiating substrate; The electric energy receiver be distributed in LED on the heat-radiating substrate around; On heat-radiating substrate, inject marine glue then, make it to form a lampshade, electric energy receiver and LED are sealed in the marine glue; Substrate and lampshade are integrated, and form an entity LED lamp that does not have the space; The electric energy receiver is made up of receiving coil, reception electric capacity, pressure limiting IC, rectifying tube and filter capacitor; Pressure limiting IC has three ends, is respectively negative terminal, control end and anode, and an end of receiving coil links to each other with the negative terminal of pressure limiting IC; The positive pole of another termination rectifying tube; Their connecting place receives electric capacity through one and links to each other with the control end of pressure limiting IC, and the negative pole of rectifier is anodal parallelly connected with filter capacitor and LED's, and the negative pole of filter capacitor, the negative pole of LED are all parallelly connected with the negative pole of pressure limiting IC; Output DC from the filter capacitor is supplied with LED and is used.

(annotate 1: the LED here refers to the above high-power light-emitting pipe of 1W that has a substrate.)

Used heat-radiating substrate is the nonmetallic materials of thermally conductive, electrically non-conductive, and its effect is that the heat that LED produces in time is delivered in the water, prevents that the junction temperature of LED from raising the life-span of guaranteeing LED; Used marine glue is the less nonmetallic materials of hot retractility, and after guaranteeing injecting glue, marine glue can not separate because of expanding with heat and contract with cold with heat-radiating substrate and cause infiltration, for example epoxy resin, atom ash, gelatin etc.

Distinguishedly be; In the present invention; The electric energy receiver receives from the energy of electrical energy transmitter and to be converted into electric energy be the LED power supply, and being connected physically not between electric energy receiver and the electrical energy transmitter, both separate fully and can keep certain distance to realize wireless power; Because the electric energy receiver is a wireless power, does not have caring for of lead, therefore for the waterproof sealing of LED lamp provides necessary condition, this can't realize in wired power supply.

During use; The circuit transmitter places the outside of container; Waterproof LED places the water of container inside, lets the transmitting coil of electrical energy transmitter and the receiving coil of electric energy receiver align basically, and electric energy just can be delivered in the LED the water through chamber wall from the outside of container and make it luminous; This product is applicable to the illumination of wet environment, like the division of swimming lane in the bathing pool, and the illumination in bathroom and the kitchen etc.; Equally also be applicable to the partition wall powered lighting, promptly give outdoor LED lamp powered lighting from the indoor wall that sees through.

The present invention has utilized the principle of wireless power to be LED power supply under water, and the waterproof type that has adopted glue to annotate, and directly in water, dispels the heat through heat-radiating substrate; Realized the effect of an active heat removal, in the life-span of having guaranteed LED, separated fully with the electric energy receiver owing to electrical energy transmitter simultaneously; Realized that LED lamp and electrical network isolate fully, stopped the possibility of electric leakage, improved security; And LED can remove arbitrarily, changes and safeguards very conveniently, is specially adapted to throw light in the wet environment.
