Technical field
The present invention relates to the rotary cooling LED floodlight of a kind of even light, belong to the LED lighting field.
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.
After the installation of existing LED floodlight, can't regulate, in the time of must carrying out the adjusting of irradiating angle, need floodlight to be pulled down, very inconvenience is installed after readjusting setting angle again by extraneous instrument to irradiating angle; Simultaneously, the emergent light intensity skewness of existing floodlight, the local intensity of illumination near apart from light source is big, has caused waste; Local intensity of illumination apart from light source is far away is poor, does not reach the requirement of illumination again, and therefore, intensity distributions is unreasonable in the hot spot of existing floodlight.
Simultaneously; Tradition LED floodlight power is little, and heat dissipation problem is not serious, as long as the Copper Foil printed circuit board (PCB) that the general electronics of utilization is used promptly is enough to deal with; But along with the high-capacity LED floodlight is more and more in vogue; Just be not enough to deal with radiating requirements, therefore need again printed circuit board (PCB) to be attached on the metallic plate, to improve its heat-transfer path.Also have a kind of way directly directly to make insulating barrier or title dielectric layer on the aluminium base surface, make circuit layer on the dielectric layer surface again, led module can directly be bonded on lead on the circuit layer.For avoiding increasing thermal impedance, take chip directly to stick together sometimes because of the poor heat conduction of dielectric layer.But above-mentioned dual mode still can't satisfy the requirement of growing LED floodlight power.
Summary of the invention
The present invention provides a kind of even light rotary cooling LED floodlight, has mainly solved existing LED floodlight can't be regulated irradiating angle, emergent light intensity skewness, heat dispersion difference after installation problem.
Concrete technical solution of the present invention is following:
Should spare the rotary cooling LED floodlight of light, and comprise led light source, LED power supply, floodlight housing and floodlight lampshade, 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, and installing rack one end is connected with firm banking through the tightening device, and the other end is connected with mounting points; The tightening device moves in draw-in groove; 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, and 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.
Above-mentioned subzero temperature groups of fins and streamline radiated rib group are integral piece.
Distance between above-mentioned each fin is 1cm-6cm.
Above-mentioned tightening device comprises screw rod and nut, said screw rod and with installing rack be integral piece.
Above-mentioned led light source is that LED crystal grain is arranged on thin-film ceramics substrate or the metal composite substrate; Accomplish through sputter, electrochemical deposition and the preparation of yellow light lithography at the thin-film ceramics substrate.
Above-mentioned floodlight housing is the housing through the aluminium alloy compression casting moulding on electrostatic spraying surface.
The invention has the advantages that:
Should the even rotary cooling LED floodlight of light when need carry out the adjusting of irradiating angle, rotate after unclamping the tightening device, again with the locking of tightening device, angle adjustment is accomplished when arriving angle on target, efficiently solves the problem that floodlight can't be adjusted irradiating angle that has now.Energy-saving and environmental protection can not pollute environment even break yet, and the recovery rate more than 99% is arranged, and are the environment-friendly and green light sources.Operating frequency is high, does not have stroboscopic effect fully, can not cause eye fatigue.The visible light ratio is high, good visual effect.Need not preheating.Can start immediately and restart, the light decay that multiple switching does not have in the normal tape electrode discharge lamp moves back phenomenon.
The light source emergent light that should spare the rotary cooling LED floodlight of light is behind the once even light of reflector; The part emergent light is through the outgoing of floodlight lampshade; Also has the part emergent light by the floodlight lampshade 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, has effectively utilized light source.
Owing to adopted the mode of subzero temperature radiated rib and streamline radiated rib combination, 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.
