Problems solved by technology

The SMD-type LED light bulb is provided with a heat dissipation structure under the aluminum substrate printed circuit board. Due to the limitation of the heat dissipation structure, the existing SMD-type LED light bulb cannot emit light at a full angle of 360°, and the arrow shown The upper part of the light is too concentrated to be glare and glare, while the lower part has a dark area near the lamp head, resulting in inconsistent brightness and uneven light intensity between the upper part and the lower part

Abstract

The embodiment of the invention provides an LED lamp. The LED lamp comprises a metal substrate structure, multiple LED units and a drive source circuit, wherein the metal substrate structure is connected with a lamp holder structure and comprises multiple structure surfaces, and the multiple LED units are fixed to the multiple structure surfaces correspondingly. In a lamp shade, at least part of light emitted by the LED units is reflected by the multiple structure surfaces, so that multiple mixed light areas are formed. The power input end of the drive source circuit is used for being connected with a power supply. The power output end of the drive source circuit is electrically connected with each LED unit. The light emitted by the LED lamp is diffusion-type light, and the light is even and not offending to the eyes; and besides, the LED lamp can achieve 360-degree light emission, and therefore a dark area of the LED lamp is eliminated.

Description

technical field [0001] The invention relates to the field of lighting lamps, in particular to an LED (Light Emitting Diode, light emitting diode) lamp. Background technique [0002] Such as figure 1 As shown, the figure shows an existing SMD (Surface Mounted Devices, surface mount device) type LED light bulb, and the direction of the arrow shown in the figure is the light emitting direction of the SMD type LED light bulb. That is, the SMD-type LED bulbs emit light in a vertical direct-illumination type, which belongs to the semi-light distribution type LED bulbs. The SMD-type LED light bulb is provided with a heat dissipation structure under the aluminum substrate printed circuit board. Due to the limitation of the heat dissipation structure, the existing SMD-type LED light bulb cannot emit light at a full angle of 360°, and the arrow shown The upper part of the light is too concentrated to dazzle the eyes, while the lower part has a dark area near the lamp head, resulting...
