Abstract

The embodiment of the invention provides an LED (Light Emitting Diode) lamp which comprises a lamp shade, a plurality of LED light sources, a first reflecting plate and a second reflecting plate, wherein the lamp shade is used for carrying out scatter diffuse on LED light radiating to the inside of the lamp shade; the LED light sources are configured into the lamp shade and are used for providing the LED light to the inside of the lamp shade; the first reflecting plate is provided with an opening, is positioned above the LED light sources and is used for reflecting part of LED light to the outlet direction of the lamp shade; and the second reflecting plate is positioned above the opening of the first reflecting plate, shields part of opening of the first reflecting plate and is used for reflecting part of the LED light entering through the opening of the first reflecting plate to the side direction of the lamp shade. According to the embodiment of the invention, the light distribution angle can be increased and the color temperature is improved.

Description

technical field [0001] The invention relates to the technical field of LEDs, in particular to an LED lamp. Background technique [0002] Since the end of the 20th century, human beings have faced severe energy problems, and it is imperative to increase revenue and reduce expenditure. Energy saving in the field of artificial lighting has great potential. According to statistics, currently about 22% of electric energy consumption (equivalent to 8% of total energy consumption) is used for inefficient artificial lighting, resulting in about 7% of carbon emissions. High-power light-emitting diodes (Light EmittingDiode, LED) can theoretically provide higher luminous efficiency (380lm / W), and have the advantages of all solid state and no pollution. Therefore, the semiconductor lighting technology using LED light source is an effective means of lighting energy saving. Among them, improving the electro-optical conversion efficiency of gallium nitride (GaN)-based power LED is the key...
