Light-emitting diode (LED) round pendant lamp

Abstract

The invention discloses a light-emitting diode (LED) round pendant lamp. The LED round pendant lamp comprises an LED light source, an LED substrate used for bearing the LED light source, and a reflector used for secondary light distribution on LED light emitted from the LED light source. The LED substrate is fixedly connected with the bottom end of the reflector, and reflection surfaces of the reflector are placed above the LED light source and comprise a first reflection surface, a horizontal reflection surface and a third reflection surface, wherein the first reflection surface is a cone frustum curved surface, the horizontal reflection surface is a ring-shaped horizontal plane, and the third reflection surface is a cone curved surface. An included angle between the LED substrate and the horizontal reflection surface and the opening towards the third reflection is from 10degrees to 45degrees, an included angle between the first reflection surface and the horizontal reflection surface and the opening towards the third reflection is from 95degrees to 120degrees, and a supplementary angle of the included angle between the third reflection surface and the horizontal reflection surface and the opening towards the LED substrate is from 15degrees to 30degrees. The LED round pendant lamp has the advantages of being good in anti-dazzle effect, high in lighting efficiency and attractive in whole appearance.

Description

technical field [0001] The invention relates to the field of lighting fixtures, in particular to an LED circular dome light. Background technique [0002] The extremely bright light or strong brightness contrast produced by the reflection of a very bright light source will cause glare to the audience. Glare will not only cause visual discomfort, but also strong glare can damage vision and even cause blindness. [0003] At present, it is more common for ceiling lamps to use fluorescent tubes as the light source, and they are arranged in the order of single, two, three, four, etc. in the reflector. The canopy lights arranged in the above sequence occupy relatively large volume and high cost. In addition, the exposed fluorescent tubes are easy to absorb dust and debris, and are difficult to clean, thereby affecting the lighting effect and easily causing glare, which makes people feel uncomfortable. In addition, the commonly used LED reflective light distribution is often domi...

AI Technical Summary

Problems solved by technology

The canopy lamps arranged in the above order occupy a relatively large volume and high cost. In addition, the fluorescent tubes are exposed, which is easy to absorb dust and debris, and is difficult to clean, thereby affecting the lighting effect and easily causing glare, which makes people feel uncomfortable.

In addition, the commonly used LED reflective light distribution is often dominated by the direct type. The glare area is directly below the lamp, and the light source directly enters the human eye, causing glare, and even causing human eye fatigue or injury. Therefore, the glare problem of ceiling lighting is solved. Very important
