Description
Technical field
The present invention relates to a kind of rotary photodetachment LED floodlight, belong to the LED lighting field with protection chain sling and 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 photodetachment 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, existing floodlight is when vibrations of high frequencies such as roadbed, rail and the medium-term and long-term work of hot environment, its fixed connection apparatus may be thrown off from mounting points owing to vibrations, cause the accident, existing floodlight light source generally all is arranged on the floodlight housing with power supply and does not exist together mutually the position of homonymy, caused the concentrated heating of light source and power supply like this, be unfavorable for heat radiation, long-term use may cause the damage of burning of power supply or light source; It is very complicated that being arranged so that of single light source regulated hot spot, part hot spot even can't form.
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 a kind of rotary photodetachment LED floodlight with protection chain sling and groove, mainly solved existing photodetachment LED floodlight after installation, can't regulate in irradiating angle, the vibration environment directly from mounting points come off, the light source power position overlaps and is unfavorable for dispelling the heat and can't adjusts the problem that hot spot, lamp body heat dispersion and weight can't balances arbitrarily.
Concrete technical solution of the present invention is as follows:
The rotary photodetachment LED floodlight of this band protection chain sling and groove, comprise led light source, 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, and the tightening device moves in draw-in groove; Described floodlight dorsal part also is provided with at least two root guard chain slings, and described floodlight housing dorsal part is provided with heat abstractor; Described led light source is two, and two led light sources are symmetricly set in floodlight housing light source side; Described LED power supply is arranged in the heat abstractor of floodlight housing dorsal part, in the centre at the back side, position, two led light source positions and do not overlap with led light source, 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 protection chain sling is two, is symmetricly set on the fixed connection apparatus outside.
Above-mentioned protection chain sling is earlier through spraying the manganese steel chain or the alloy steel chain of electrophoretic paint after the electroplating processes again.
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 photodetachment LED floodlight of this band protection chain sling and 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.
This floodlight has been set up the protection chain sling; when fixed connection apparatus is thrown off mounting points owing to vibrations; play the temporary protection effect; prevented the generation of accident; also make simultaneously floodlight have stronger anti-powerful collision and impact capacity, can be in vibrations of high frequencies such as roadbed, rail and the medium-term and long-term work of hot environment.
Because led light source is divided into two, emergent light distributes more even, can also utilize difform floodlight lampshade to adjust the light spot shape of emergent light, make hot spot adjustable, light is soft evenly, free from glare, can effectively avoid staff's discomfort and fatigue strength, increases work efficiency; Simultaneously, light source and power supply have carried out physical separation, are beneficial to heat radiation more, have increased the service life of light fixture.
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.
