Abstract

The invention discloses a light emitting diode (LED) illuminating lamp. The lamp comprises a lamp cap and a glass shell, wherein a glass core column is arranged in the glass shell; a wire is led out of the glass core column; the top of the glass core column is fixedly provided with a first copper-clad plate; a plurality of circuit boards which are tightly adjacent and enclose a circle are arranged at the periphery of the first copper-clad plate and are vertical to the first copper-clad plate; a plurality of LED chips are welded on each circuit board; a second copper-clad plate is fixed on the tops of the circuit boards; a plurality of LED chips are welded on the second copper-clad plate; an LED driver is arranged in a cavity formed by enclosing the first copper-clad plate, the circuit boards and the second copper-clad plate; the wire is connected with the LED driver; and the circuit boards and the second copper-clad plate are connected with the LED driver. In the LED illuminating lamp, the plurality of circuit boards with the LED chips enclose the circle, and the LED chips are arranged on one copper-clad plate on the tops of the circuit boards, so that an illuminating area is expanded, dead zone free illumination is realized, service life can be prolonged, and energy consumption is reduced.

Description

technical field [0001] The invention relates to the technical field of LEDs, in particular to an LED lighting lamp. Background technique [0002] Energy saving and emission reduction is a hot spot in the world today. Due to the rapid development of LEDs, it is an inevitable trend to replace incandescent lamps with LEDs. [0003] LED is a solid-state light emitting device, which has the advantages of energy saving and high efficiency, and adapts to the sustainable development goals of energy saving and emission reduction proposed in today's world. Home lighting requires a popular LED light bulb that is energy efficient. [0004] However, LED has the disadvantage of low illumination angle, its light emission is directional, and its light angle is limited, which will cause lighting blind spots in some areas around the LED and affect its lighting effect. Contents of the invention [0005] The present invention overcomes the disadvantages of the above-mentioned prior art, and...
