Description
Technical field
The present invention relates to a kind of even light cooling LED pendent lamp, belong to the LED lighting field with chain sling and installing plate.
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, in semiconductor, through carrier compound energy of emitting surplus takes place and causes photo emissions, 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.
Existing pendent lamp generally all adopts two chain slings to hang, and so not only intensity has problems, and is difficult to make the pendent lamp balance.Simultaneously; Existing pendent lamp generally all is connected the upper end with the built-in fitting of building; Like this when when regulating the pendent lamp balance, because adding man-hour its length, chain sling possibly have error, need chain sling is blocked to meet the demands; This mode possibly destroyed the reliability of chain sling, and pendent lamp possibly cause the chain sling fracture when long-term the use; Simultaneously, can't regulate after the existing pendent lamp installation; And light distribution is inhomogeneous in the hot spot that emergent light forms, and is prone to cause energy waste.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 that LED can not strengthen the fundamental cause of input power, is because LED can emit a large amount of heat in the course of the work, and the tube core junction temperature is risen rapidly, and 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, and non-radiation recombination increases, and the leakage current of device increases, and defects from semiconductor materials increases, the metal electrode electromigration, and 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 through the wind of one or two direction, and radiating efficiency is low, and long-time use possibly cause light source or power supply to damage.
Summary of the invention
The present invention provides a kind of even light cooling LED pendent lamp with chain sling and installing plate; Mainly solved existing pendent lamp chain sling irrational distribution; Balance is poor, reliability is low, heat dispersion is poor, it is inhomogeneous to regulate in the hot spot that height and angle, emergent light form light distribution, is prone to the problem that causes energy waste, can't use for a long time.
Technical solution of the present invention is following:

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 chain sling is earlier through spraying the manganese steel chain or the alloy steel chain of electrophoretic paint after the electroplating processes again.
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:
The chain sling of the even light cooling LED pendent lamp of this band chain sling and installing plate distributes rationally; Bonding strength is big, and the even distribution of four chain slings makes that the pulling force that each chain sling bore is identical, and is not fragile; Can adapt to various operating mode; Chain sling adopts manganese steel chain sling, steel alloy chain sling, good rigidly, and plating, electrophoresis plating are difficult for getting rusty, fall lacquer.
The design of installing plate can be regulated the height and the angle of light fixture at any time through the installing hole on the installing plate, solved existing pendent lamp and can't effectively regulate comparatively complicated problems of height, angle and adjustment light fixture height and angle.
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.
Owing to adopted the mode of subzero temperature radiated rib and streamline radiated rib combination, 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.
