The uniform-light negative-temperature radiating LED (light-emitting diode) ceiling lamp comprises a reflecting lens and a reflecting cup, wherein the reflecting lens and the reflecting cup are arranged in a ceiling lamp cover and are fixedly connected with a light source side of a ceiling lamp shell; one side of the reflecting surface of the reflecting cup arranged on the reflecting lens is coincidental to the central point of the reflecting cup; the LED (light-emitting diode) light source is arranged on the central point of the reflecting surface and the reflecting cup; the radiating device is arranged on the back side of the ceiling lamp shell; the radiating device consists of uniformly distributed ribs and comprises a negative-temperature radiating part and a streamline radiating part, wherein the negative-temperature radiating part is formed by negative-temperature radiating rib groups arranged on the ceiling lamp shell in height direction; and the streamline radiating part is formed by streamline radiating rib groups that are arranged on the ceiling lamp shell in width direction.
Description
Technical field
The present invention relates to a kind of even light type subzero temperature cooling LED pendent lamp, belong to the LED lighting field.
Background technology
The LED illumination promptly is a led lighting, is a kind of semiconductor solid luminescence device.It is to utilize the solid semiconductor chip as luminescent material, by carrier compound energy of emitting surplus takes place and cause photo emissions in semiconductor, directly sends red, yellow, blue, green, blue or green, orange, purple, white light.The LED illuminating product utilizes LED as the produced ligthing paraphernalia of light source exactly.
Pendent lamp generally must be fixed with chain sling, suspension hook hanging, and the upper end is connected with the built-in fitting of building, and pendent lamp light requires can not hinder people's normal line of sight, also can not hinder the sight line that the people hopes mutually, or make us feeling dazzling.It is appropriate that the canopy Material Selection is wanted, and do not adopt and can generation make us uncomfortable dazzle.When the lampshade moulding was complicated, in the environment of moist, many dirt, light fixture got rusty easily, falls lacquer, and lampshade covers dirt light can be day by day dim, did not often maintain, cleaned, and illumination one annual reduces approximately 30 percent according to statistics, does not go out several years, and pendent lamp is with dim nothings brilliance.
Its emergent light intensity skewness of existing pendent lamp, place near light source is too bright, place away from light source is too dark, need a plurality of pendent lamps when throwing light on a large scale, and the distance between each pendent lamp can not be far away excessively, caused the waste of the energy, simultaneously, along with the increase of power, the heat dissipation problem of LED seems more and more outstanding, and a large amount of practical applications show, LED can not strengthen the fundamental cause of input power, be because LED can emit a large amount of heat in the course of the work, the tube core junction temperature is risen rapidly, it is big that thermal resistance becomes.Input power is high more, and heating effect is big more.The rising of temperature will cause device performance to change and decay, non-radiative compound increase, and the leakage current of device increases, and defects from semiconductor materials increases, the metal electrode electromigration, encapsulating epoxy resin yellow or the like has a strong impact on the photoelectric parameter of LED.Even power LED was lost efficacy.Therefore, for the LED device, reduce thermal resistance and junction temperature, thermal characteristics research of light emitting diode is seemed increasingly important.And the heat abstractor of existing pendent lamp generally can only dispel the heat by the wind of one or two direction, and radiating efficiency is low, and long-time use may cause light source or power supply to damage.
Summary of the invention
The invention provides a kind of even light type subzero temperature cooling LED pendent lamp, mainly solved light distribution in the hot spot that existing pendent lamp emergent light forms inhomogeneous, easily cause the problem of energy waste, heat dispersion difference.
Technical solution of the present invention is as follows:
Should spare light type subzero temperature cooling LED pendent lamp, comprise led light source, LED power supply, pendent lamp housing and canopy, described canopy is arranged at the led light source outside and is connected with pendent lamp housing light source side, described even light type subzero temperature cooling LED pendent lamp also comprises speculum and reflector, speculum and reflector are located in the canopy, fixedly connected with the light source side of pendent lamp housing; Reflector is arranged at reflecting surface one side of speculum and overlaps with the reflector central point, led light source is arranged on the central point of reflecting surface and reflector, pendent lamp housing dorsal part is provided with heat abstractor, described heat abstractor is made up of equally distributed fin, comprise subzero temperature radiating part and streamline radiating part, described subzero temperature radiating part is arranged on the subzero temperature radiated rib group on the pendent lamp housing short transverse, and the streamline radiating part is arranged on the streamline radiated rib group on the pendent lamp housing width.
Above-mentioned subzero temperature groups of fins and streamline radiated rib group are integral piece.
Distance between above-mentioned each fin is 5cm-10cm.
Above-mentioned canopy is sphere, hemispherical, oblateness, discoid, square, rectangle, rhombus, triangle, taper, olive shape or tassel shape etc.
The invention has the advantages that:
Even light type subzero temperature cooling LED pendent lamp provided by the invention, the emergent light of its led light source is through behind the once even light of reflector, the part emergent light is through the canopy outgoing, also has the part emergent light by canopy once more in the reflected back lamp body, at this moment reflect at the speculum that is different from reflector through radian, emergent light is more even, and it has effectively utilized light source; Simultaneously, owing to adopted the mode of subzero temperature radiated rib and the combination of streamline radiated rib, improved the heat-sinking capability of light fixture, its wind that can effectively utilize a plurality of different directions dispels the heat to lamp body.
