Problems solved by technology

[0003] However, LED has the disadvantage of low illumination angle, and its limited illumination angle will cause some areas around the LED to form a lighting blind area, which affects its lighting effect. Although it can save energy and have a long service life, the luminous effect sometimes does not reach to the effect of an incandescent lamp

Abstract

The invention discloses an LED (light emitting diode) lamp. The LED lamp comprises a lamp holder and a bulb shell, wherein an LED glowing module is arranged in the bulb shell, and the LED glowing module comprises a glass core column and two circuit boards; the two circuit boards are fixed together in a cross manner, a wire is led out from the glass core column, and the wire and the lower end of one of the circuit boards are fixed in a welding manner; a crisscross circuit board is fixed on the tops of the two circuit boards, and flat surfaces on which the two circuit boards are respectively positioned are both vertical to a flat surface on which the crisscross circuit board is positioned; and multiple LED chips are welded on the two cross circuit boards and the crisscross circuit board. In the LED lamp provided by the invention, a glowing tungsten wire in an incandescent bulb shell is replaced by the LED glowing module, the LED glowing module is used for fixing the two circuit boards together in a cross insertion manner, and the tops of the two circuit boards are provided with the crisscross circuit board, and the LED chips are fixed on both circuit boards; and the LED lamp provided by the invention has the advantages that an illuminated area is enlarged, no blind area lighting is formed, the service life is prolonged, and the energy consumption is reduced.

Description

technical field [0001] The invention relates to the technical field of LEDs, in particular to an LED lamp that can replace an incandescent 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] However, LED has the disadvantage of low illumination angle, and its limited illumination angle will cause some areas around the LED to form a lighting blind area, which affects its lighting effect. Although it can save energy and have a long service life, the luminous effect sometimes does not reach to the effect of an incandescent lamp. Contents of the invention [0004] The present invention overcomes the disadvantages of the above-mentioned prior art, and provides an LED lamp that can increase the luminous angle and expand the irradiation range, so that the existing incandescent lamp can be replaced, and the purpos...
