Description
Technical field
The present invention relates to a kind of even light heat radiating type photodetachment LED pendent lamp, belong to the LED lighting field with 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, 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 is connected the upper end with the built-in fitting of building, like this when when regulating the pendent lamp balance, because chain sling adds man-hour its length and may have error, need chain sling is blocked to meet the demands, this mode may be destroyed the reliability of chain sling, and pendent lamp may cause the chain sling fracture when long-term the use; Simultaneously, can't regulate after the existing pendent lamp installation, and its emergent light intensity skewness of pendent lamp, place near light source is too bright, and is too dark away from the place of light source, needs 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; And existing pendent lamp light source generally all is arranged on the pendent lamp housing with power supply and do not exist together mutually the position of homonymy, caused the concentrated heating of light source and power supply like this, is unfavorable for heat radiation, and use for a long time may cause the damage of burning of power supply or light source; Simultaneously, single light source be arranged so that hot spot is non-adjustable, it is very complicated perhaps to regulate hot spot.
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 radiating type photodetachment LED pendent lamp with installing plate, mainly solved existing pendent lamp can't regulate height and angle, be difficult to pendent lamp hang that light distribution is inhomogeneous in the hot spot of flat, emergent light formation, heat dispersion is poor, easily cause energy waste, the pendent lamp light source is arranged on the pendent lamp housing with power supply and do not exist together mutually the position of homonymy, the concentrated heating of light source and power supply and the nonadjustable problem of hot spot.
