LED LIGHTING DEVICE

摘要

An LED lighting apparatus comprising: a base, a circuit coating, a light-emitting chip, and a light shade. The base is an openwork structure. The circuit coating is coated directly onto the upper surface of the base. The light-emitting chip is directly affixed onto the base and is connected thereto via the circuit coating. The light shade is arranged on the base and covers the light-emitting chip and the circuit coating. The inner surface of the light shade comprises a light distribution surface and a thermally-conductive surface. The thermally-conductive surface is distributed at least in the center area and the edge area of the inner surface. The LED lighting apparatus employs a solid material having an improved thermal conductivity as the light shade and, at the same time, employs an openwork base and heat-dissipating through holes, heat generated by the chip can be transferred outwards via the base and the light base and then carried away by air flowing through the openwork and the through holes, thus allowing the entire apparatus to dissipate heat in all directions, and increasing the heat dissipation performance of the apparatus.
