Abstract

The invention relates to a high-power LED energy-saving bulb, which comprises an LED light source, a circuit board, a radiator, an LED driving device, a connector for connecting with an interface of an illumination lamp, and a reflecting cup base, wherein the upper part of the reflecting cup base is provided with a flat-bottomed bowl cup which is provided with a reflecting layer, the connector is provided with a cavity, the LED driving device is fixed in the cavity, the radiator is a metal radiator provided with a vertical radiating fin, the upper part of the connector is fixedly connected with the lower part of the radiator, the lower part of the reflecting cup base is fixedly connected with the upper part of the radiator, the LED light source is fixed on the circuit board, the circuit board is fixed on the flat-bottomed bowl cup, a bulb cover is fixed on the flat-bottomed bowl cup, and the vertical radiating fin is provided with at least one radiating rib groove. The high-power LED energy-saving bulb has the advantages of higher light efficiency, better radiating effect, lower cost, and more reliable structural performance, and is more suitable for mass production and widespread use.

Description

technical field [0001] The invention relates to an energy-saving lighting fixture, in particular to a high-power LED energy-saving light bulb. Background technique [0002] Traditional lighting lamps generally have low light efficiency and short life, and often cause unsafe accidents due to high temperature during work. At the same time, some lamps contain many harmful substances such as mercury and cadmium, which are easy to leak and cause pollution to the environment or It causes harm to the human body and is not conducive to environmental protection, so people are constantly looking for a new type of lighting fixture that is environmentally friendly, efficient, safe and reliable. [0003] LED lights are a new type of environmental protection, high efficiency, safer and more reliable lighting fixtures. With the continuous maturity of high-power LED lighting technology, the proportion of LED lamps in the lighting market is also increasing. Complicated, high cost, low ligh...
