Description
Technical field
The present invention relates to a kind of even light heat dissipation LED pendent lamp, belong to the LED lighting field with chain sling.
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.
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, its emergent light intensity skewness of existing pendent lamp, too bright near the place of light source, too dark away from the place of light source, need a plurality of pendent lamps when throwing light on, and the distance between each pendent lamp can not be far away excessively, caused the waste of the energy on a large scale.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, 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 heat dissipation LED pendent lamp with chain sling, mainly solved existing pendent lamp chain sling irrational distribution, balance is poor, reliability is low, in the hot spot that emergent light forms light distribution inhomogeneous, heat dispersion is poor, easily causes the problem of energy waste.

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 even light heat dissipation LED pendent lamp chain sling of this band chain sling distributes rationally, bonding strength is big, the even distribution of four chain slings makes that the pulling force that each chain sling bore is identical, 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.
Simultaneously, the emergent light of the led light source of the even light heat dissipation LED pendent lamp of this band chain sling 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.
The even light heat dissipation LED pendent lamp of this band chain sling has improved the heat-sinking capability of light fixture owing to adopted the mode of subzero temperature radiated rib and the combination of streamline radiated rib, and its wind that can effectively utilize a plurality of different directions dispels the heat to lamp body.
