Description
Technical field
The present invention relates to a kind of heat dissipation LED pendent lamp, belong to the LED lighting field with installing plate and groove.
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.
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.Simultaneously, improve heat-sinking capability for highland as far as possible, the vent rib of existing heat abstractor is all higher, has caused increasing considerably of pendent lamp weight like this, and long-term use may produce potential safety hazard, even causes the generation of accident.
Summary of the invention
The invention provides a kind of heat dissipation LED pendent lamp, solved mainly that existing pendent lamp can't be regulated height and angle, being difficult to that pendent lamp is hung flat, heat dispersion and weight can't balance, the problem of heat dispersion difference with installing plate and groove.
Technical solution of the present invention is as follows:
The heat dissipation LED pendent lamp of this band installing plate and groove, 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, the heat dissipation LED pendent lamp of described band installing plate and groove is fixed on the installation position by installing plate, and chain sling is connected with installing plate; Described installing plate is provided with the chain sling installing hole identical with the chain sling number, installing plate is similar to the shape of pendent lamp housing, also be provided with on the installing plate and be mounted a jockey that is connected, described 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, the streamline radiating part is arranged on the streamline radiated rib group on the pendent lamp housing width, it is characterized in that: described pendent lamp housing dorsal part is provided with heat abstractor, the centre of heat abstractor is provided with groove, the width of groove is 1/3～1/4 of a fin width, and the degree of depth of groove is 1/2～9/10 of a fin maximum height.
The cross section of above-mentioned groove is rectangle, arch or ellipse.
Be provided with the frock hole in the above-mentioned groove, the height in frock hole is less than groove height.
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:
The design of installing plate can be regulated the height and the angle of light fixture at any time by 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.
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.
Owing to adopted groove structure, balance the heat dispersion of pendent lamp and the contradiction between the weight, simultaneously, do not weaken heat sinking function yet, also improved the reliability that light fixture uses; The frock hole is arranged in the groove, also can not produce any influence to the installation and the maintenance of light fixture.
