Problems solved by technology
[0003] Traditional indoor chandeliers need external wires to supply power, which affects the indoor appearance. Even though some indoor chandeliers are composed of multiple low-power LEDs, due to LED layout or thermal design defects, they lead to short life, easy aging, and inconvenient movement. For public In terms of facility use, it also increases maintenance costs

Embodiment Construction
[0019] The intelligent LED indoor chandelier of the present invention will be described in detail below in conjunction with examples and accompanying drawings.
[0020] like figure 1 As shown, the 220V AC power is connected to the DC stabilized power supply, and the 100V DC output is realized to the transmitter device after rectification and stabilization. In the transmitter device, it is converted into an AC voltage signal through high-frequency inversion, and loaded into the compensated loosely coupled transformer. The primary side is resonantly coupled with the receiving coil embedded in the LED indoor chandelier. After a secondary rectification and boost circuit, the 220V voltage is supplied to the main chip set of the light. The LED matrix that has been thermally designed and optimized by engineering realizes the LED indoor lighting. The high brightness of the chandelier.
[0021] like figure 2 As shown, the DC power in the storage battery is sent to a rectifier bridge...

Abstract
The invention discloses an intelligent LED indoor ceiling lamp of wireless power supply, which comprises a direct current voltage stabilizing power supply, an emitting device and a light emitting main chip, wherein the direct current voltage stabilizing power supply is provided with a primary rectifier; and the light emitting main chip comprises LED matrixes which are thermally designed through engineering and optimally distributed, wherein a receiving device and a secondary rectifier bridge booster circuit are embedded in the ceiling lamp. A common 220V illuminating power supply is needed to be used, when a sensing device is externally connected, and the LED indoor ceiling lamp is automatically controlled to be switched on or off. The intelligent LED indoor ceiling lamp is convenient, intelligent and quick in use, realizes ideas of saving energy and protecting environment while the quality requirement of durability is achieved, and can be widely applied to ordinary residents.
Description
technical field [0001] With the innovation and progress of science and technology, various household appliances based on wireless power transmission technology will enter thousands of households. The so-called "wireless power transmission" is to use a special device to convert the electric energy of the power supply into energy that can be transmitted wirelessly, and then convert this energy back to electric energy at the receiving end, so as to achieve wireless power supply to electrical appliances. [0002] The present invention—intelligent LED indoor chandelier with wireless power supply, belongs to the brand-new application field of non-contact power transmission technology. The matrix structure is simple, convenient, intelligent and flexible, and realizes the concept of energy saving and environmental protection in terms of durable quality requirements, and can be widely used in ordinary residents' homes. Background technique [0003] Traditional indoor chandeliers nee...
