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

Embodiment Construction

[0018] The present invention will be further described below in conjunction with accompanying drawing.

[0019] Such as figure 1 , 2 1. An LED anti-glare dome light shown in 3, including LED light source 1, LED substrate 2 for carrying LED light source and reflector 3 for secondary light distribution of LED light emitted by LED light source, LED substrate 2 It is fixedly connected with the bottom of the reflector 3, and the reflecting surface of the reflector 3 is located above the LED light source 1. The angle α between the surfaces is 10°~45°, preferably 15°; the angle β between the first reflective surface and the horizontal reflective surface can be 95°~120°, preferably 102°; the third reflective surface and the horizontal The complementary angle γ of the included angle between the reflective surfaces may be 15°-30°, preferably 21°.

[0020] The above-mentioned reflector 2 can be composed of multiple plates (such as aluminum) spliced ​​with each other, or can be formed ...

Abstract

The invention discloses an LED (light-emitting diode) anti-dazzling ceiling lamp, which comprises LED light sources, LED substrates which are used for bearing the LED light sources, and reflectors which are used for conducting secondary light distribution on light emitted by the LED light sources. The LED substrates are fixedly connected with the bottom ends of the reflectors. The reflecting surface of each reflector is arranged above the LED light sources and comprises a first reflecting surface, a horizontal reflecting surface and a third reflecting surface which are flat surfaces, wherein included angles between the LED substrates and the horizontal reflecting surfaces are 10-45 degrees, included angles between the first reflecting surfaces and the horizontal reflecting surfaces are 95-120 degrees, and the supplementary angles of included angles between the third reflecting surfaces and the horizontal reflecting surfaces are 15-30 degrees. The LED anti-dazzling ceiling lamp has the advantages of good anti-dazzling effect, high luminous efficiency, energy saving and consumption reduction.

Description

technical field [0001] The invention relates to the field of lamp lighting, in particular to an LED anti-glare ceiling lamp. 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...
