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
The present invention relates to field of lamp illumination, relate in particular to the anti-dazzle fluffy ceiling light of a kind of LED.
Background technology
The light that the brightness that the high light source process reflection of brightness produces is high or strong brightness contrast will allow spectators produce dazzle.Dazzle not only can cause visual inadaptable sense, and strong dazzle also can damage vision even cause blind.
Fluffy ceiling light at present more commonly by fluorescent tube as light source, by single, order collating units such as two, three, four in reflector.Adopt fluffy ceiling light that above-mentioned order arranges its to take volume relatively large, cost is high, fluorescent tube is exposed in addition, adsorb easily dust foreign material, easy to clean not, thereby impact illumination light efficiency also causes dazzle easily, and the people is felt under the weather.In addition, LED reflection-type luminous intensity distribution commonly used is often take straight-down negative as main, and the dazzle zone is under light fixture, and light source is directly injected human eye, produces glare phenomenon, even causes people's kopiopia or injury, and the glare problem that therefore solves fluffy ceiling light illumination is extremely important.
Summary of the invention
The technical problem to be solved in the present invention is, for the defects of prior art, provides the anti-dazzle fluffy ceiling light of the LED that a kind of antiglare effect is good, luminous efficiency is high.
The technical solution adopted for the present invention to solve the technical problems is: the anti-dazzle fluffy ceiling light of a kind of LED, it is characterized in that, comprise led light source, the reflector that is used for the LED substrate of carrying led light source and is used for the LED light of led light source emission is carried out secondary light-distribution, described LED substrate is fixedly connected with the reflector bottom, the reflecting surface of described reflector is positioned at the top of led light source, comprise the first reflecting surface that is the plane, horizontal reflection face and the 3rd reflecting surface, wherein, angle between described LED substrate and the horizontal reflection face is 10 °～45 °, angle between described the first reflecting surface and the horizontal reflection face is 95 °～120 °, and the supplementary angles of angle is 15 °～30 ° between described the 3rd reflecting surface and the horizontal reflection face.
Further, the anti-dazzle fluffy ceiling light of LED of the present invention, it is characterized in that, preferred 15 ° of angle between described LED substrate and the horizontal reflection face, preferred 102 ° of angle between described the first reflecting surface and the horizontal reflection face, the supplementary angles of angle is preferred 21 ° between described the 3rd reflecting surface and the horizontal reflection face.
Further, the anti-dazzle fluffy ceiling light of LED of the present invention is characterized in that described reflector wide cut is 150～400mm, and length is 200～800mm.
Further, the anti-dazzle fluffy ceiling light of LED of the present invention is characterized in that the vertical range of described LED substrate bottom and described reflector horizontal reflection face is 20～80mm.
Further, the anti-dazzle fluffy ceiling light of LED of the present invention is characterized in that, the preferred 37.7mm of vertical range of described LED substrate bottom and described reflector horizontal reflection face.
Further, the anti-dazzle fluffy ceiling light of LED of the present invention is characterized in that, the uniform led light source that arranges of described LED substrate, and uniform spacing is 20～150mm.
Further, the anti-dazzle fluffy ceiling light of LED of the present invention is characterized in that described led light source is white light LEDs, and power is 1W, 2W, 3W or 4W.
The anti-dazzle fluffy ceiling light of LED of the present invention changes in the past reflection-type and directly descends light-configuration mode, has avoided the dazzle zone under light fixture, thereby has avoided light source directly to inject human eye, can effectively prevent the generation of dazzle.Because the light source that adopts is led light source, its power only is 1W, 2W, 3W or 4W, can effectively reduce lighting energy consumption, thereby reaches the green illumination target of energy-conserving and environment-protective.
