The uniform light rotation type heat dissipation LED floodlight with a protective sling chain comprises an LED light source, an LED power supply, a floodlight shell and a floodlight shade, wherein the LED power supply comprises a circuit board, a power supply box body and a power supply box cover; and a vacancy unit is independently and vertically arranged on the circuit board. According to the uniform light rotation type heat dissipation LED floodlight, the vacancy unit is vertically arranged on the circuit board and independently replaced, so that the uniform light rotation type heat dissipation LED floodlight can be suitable for the high-temperature and high-pressure environment; an air duct can be formed due to the vertical arrangement and is beneficial to airflow circulation so as to take away heat, and the heat dissipation effect is further improved; the power supply box body is an integral piece which has the advantages of uniform heat radiation and high strength; and the back of the box body is processed and can be tightly contacted with a mounted piece, which is beneficial to heat conduction.
Description
Technical field
The present invention relates to a kind of rotary cooling LED floodlight of even light, belong to the LED lighting field with the protection chain sling.
Background technology
Floodlight is a kind of spot light of uniform irradiation to all the winds, floodlight produces be the height diffusion, nondirectional light but not the light beam of clear-cut; Floodlight does not have electrode, is to lean on electromagnetic induction principle to combine with the fluorescence discharge principle and luminous, so there is not the inevitable assembly that limits the life-span in it; The shade that produces is soft and transparent, when being used for the object illumination, the speed that illumination weakens when throwing light on spotlight slowly many, even some illumination weakens very slow floodlight, looks similarly to be a light source that does not produce shade.
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.
The vacant unit of existing LED power supply is generally positioned on the wiring board, and this set-up mode is unfavorable for heat radiation, is not suitable for the operate as normal of hot and humid environment.
The existing power supply box body is generally the split part, cause the intensity of power supply box body lower like this, and the each several part heat dispersion is inconsistent, is unfavorable for heat radiation; Simultaneously, does not generally handle existing power supply box body bottom, and it is not tight to cause power supply bottom and mounted piece to be fitted, and is unfavorable for the heat conduction.
Summary of the invention
The present invention provides a kind of rotary cooling LED floodlight of even light with the protection chain sling, has mainly solved the power supply heat sinking poor performance of existing LED floodlight, works in the hot and humid environment again; The problem that existing power supply heat-conductive characteristic and intensity are relatively poor.
Concrete technical solution of the present invention is following:
A kind of rotary cooling LED floodlight of even light with the protection chain sling comprises led light source, LED power supply, floodlight housing and floodlight lampshade, and said floodlight lampshade is arranged at the led light source outside and is connected with floodlight housing light source side; The floodlight dorsal part is provided with fixed connection apparatus, and said fixed connection apparatus comprises firm banking and installing rack, and firm banking is fixedly connected with the floodlight dorsal part; And be provided with the rotation draw-in groove; Installing rack one end is connected with firm banking through the tightening device, and the other end is connected with mounting points, and the tightening device moves in draw-in groove; Said floodlight dorsal part also is provided with at least two root guard chain slings; Also comprise speculum and reflector, speculum and reflector are located in the floodlight lampshade, are fixedly connected with the light source side of floodlight housing; Reflector is arranged at reflecting surface one side of speculum and overlaps with the reflector central point; Led light source is arranged on the central point of reflecting surface and reflector; Said floodlight housing dorsal part is provided with heat abstractor; Said 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 floodlight housing short transverse, and the streamline radiating part is arranged on the streamline radiated rib group on the floodlight housing width; Said LED power supply comprises wiring board, power supply box body and power supply lid; Said wiring board is fixedly set in the power supply box body; Said power supply box body is " U " type or " L " type, comprises power pack body sidewall and power supply box plate, and wiring board is fixedly set on the power supply box plate; Said vacant unit independently is vertically installed on the wiring board, and the operating temperature of vacant unit is-40 ℃～100 ℃; Said power supply box plate away from circuit board one side be mounted the position and fit the insulating heat-conductive box that power supply box plate and power pack body sidewall are formed in one fully.
The invention has the advantages that:
1, the power supply of the rotary cooling LED floodlight of even light of this band protection chain sling is taked mounting means is in the circuit board erect in vacant unit; Be provided with like this and be prone to heat radiation; Can carry out independent replacing to vacant unit; Be applicable to hot and humid environment, can be at-40 ℃～100 ℃, operate as normal in 90% humidity environment; When humidity in the power supply was big, dew can flow down along the wiring board of erectting; Simultaneously, erect setting and can form the air channel, be beneficial to airflow and take away heat, further improved radiating effect.
2, the power supply box body of the rotary cooling LED floodlight of even light of this band protection chain sling is an integral piece, and heat radiation is even, and intensity is high; Simultaneously, the box body back is handled, make its with mounted piece between contact closely, be beneficial to the heat conduction.
