Description
Technical field
The present invention relates to a kind of even smooth heat radiating type optical-electric separation LED ceiling lamp with chain sling and groove, belong to field of LED illumination.
Background technology
Namely LED illumination is LED lighting, is a kind of semiconducting solid luminescent device.It utilizes solid semiconductor chip as luminescent material, releases superfluous energy in the semiconductors and cause photo emissions, directly send red, yellow, blue, green, blue or green, orange, purple, white light by carrier generation compound.LED illumination 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 upper end is connected with the built-in fitting of building, and pendent lamp lighting demand can not hinder the normal line of sight of people, also can not hinder the sight line that people hopes mutually, or makes us feeling dazzling.The selection of canopy material wants appropriate, adopts to produce and makes us uncomfortable dazzle.When lampshade moulding is more complicated, in the environment of humidity, many dirt, light fixture gets rusty easily, fall paint, and lampshade covers dirt light can be day by day dim, infrequently maintains, cleans, and illumination one annual reduces by 30 about percent according to statistics, does not go out several years, and pendent lamp is by honorable for dim nothing.
Existing pendent lamp generally all adopts two chain slings to hang, so not only intensity existing problems, and is difficult to pendent lamp is balanced; Meanwhile, its exiting light beam intensity skewness of existing pendent lamp, the place near light source is too bright, and the place away from light source is too dark, need multiple pendent lamp, and the distance between each pendent lamp can not be excessively far away, causes the waste of the energy when throwing light on a large scale; Meanwhile, the light source of existing pendent lamp is generally all arranged on pendent lamp housing not homonymy position with power supply exists together mutually, and this results in the concentrated heating of light source and power supply, be unfavorable for heat radiation, Long-Time Service may cause the damage of burning of power supply or light source; Meanwhile, single light source be arranged so that hot spot is non-adjustable, or regulate hot spot very complicated.
Along with the increase of power, the heat dissipation problem of LED seems more and more outstanding, and a large amount of practical application shows, LED can not strengthen the fundamental cause of input power, is because LED can release a large amount of heat in the course of the work, makes tube core junction temperature increase rapidly, and thermal resistance becomes large.Input power is higher, and heating effect is larger.The rising of temperature will cause device performance to change and decay, and non-radiative recombination increases, and the leakage current of device increases, and defects from semiconductor materials increases, and metal electrode electromigration, encapsulating epoxy resin yellow etc., has a strong impact on the photoelectric parameter of LED.Power LED is even made to lose efficacy.Therefore, for LED component, reduce thermal resistance and junction temperature, research is carried out to the thermal characteristics of light emitting diode seem increasingly important.And the heat abstractor of existing pendent lamp generally can only be dispelled the heat by the wind in one or two direction, radiating efficiency is low, and long-time use may cause light source or power supply to damage.In order to heat-sinking capability is improved on highland as far as possible, the vent rib of existing heat abstractor is all higher, this results in increasing considerably of pendent lamp weight, and Long-Time Service may produce potential safety hazard, even causes the generation of accident.
Summary of the invention
The invention provides a kind of even smooth heat radiating type optical-electric separation LED ceiling lamp with chain sling and groove, mainly solve existing pendent lamp chain sling irrational distribution, in the hot spot that balance is poor, emergent light is formed light distribution uneven, easily cause energy waste, heat dispersion is poor, heat dispersion cannot balance with weight, pendent lamp light source and power supply are arranged on pendent lamp housing not homonymy position exists together mutually, the concentrated heating of light source and power supply and the nonadjustable problem of hot spot.
