Description
Technical field
The present invention relates to the rotary cooling LED floodlight of a kind of even light, belong to the LED lighting field with groove.
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 combine with the fluorescence discharge principle and luminous by electromagnetic induction principle, 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, 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.
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, install again after readjusting setting angle by extraneous instrument to irradiating angle, very inconvenient; Simultaneously, the emergent light intensity skewness of existing floodlight, the local intensity of illumination near apart from light source is big, has caused waste; Poor apart from the local intensity of illumination that light source is far away, do not reach the requirement of illumination again, therefore, intensity distributions is unreasonable in the hot spot of existing floodlight.
Simultaneously, tradition LED floodlight power is little, 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.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 floodlight 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 the rotary cooling LED floodlight of a kind of even light, the problem of solved mainly that existing LED floodlight can't regulate after installation that irradiating angle, emergent light intensity skewness, heat dispersion are poor, lamp body heat dispersion and weight can't balances with groove.
Concrete technical solution of the present invention is as follows:
The rotary cooling LED floodlight of even light of this band groove, comprise led light source, the LED power supply, floodlight housing and floodlight lampshade, described 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, described fixed connection apparatus comprises firm banking and installing rack, firm banking is fixedlyed connected with the floodlight dorsal part, and be provided with the rotation draw-in groove, installing rack one end is connected with firm banking by the tightening device, 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, 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; Described floodlight 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 floodlight housing short transverse, the streamline radiating part is arranged on the streamline radiated rib group on the floodlight housing width, the centre of described 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 1cm-6cm.
Above-mentioned tightening device comprises screw rod and nut, described screw rod and and 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; Finish by 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:
The rotary cooling LED floodlight of the even light of this band groove is in the time need carrying out the adjusting of irradiating angle, rotate after unclamping the tightening device, again with the locking of tightening device, angle adjustment is finished when arriving angle on target, efficiently solves the problem that existing floodlight can't be adjusted irradiating angle.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.The operating frequency height does not have stroboscopic effect fully, can not cause eye fatigue.Visible light ratio height, 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 of the rotary cooling LED floodlight of even light of this band groove 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 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 floodlight 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.
