The utility model content
For above-mentioned prior art, the technical problems to be solved in the utility model is: iodine-tungsten lamp does that the searchlight power of light source is excessive, the life-span short, price, and packaging effect is poor.
In order to solve the problems of the technologies described above, the utility model adopts following technical scheme:
A kind of LED searchlight, comprise driving power, housing, it is characterized in that, also comprise LED lamp, reflector, radiator, the aluminium base of 3 ~ 10W, described aluminium base is fixed on the radiator through heat-conducting silicone grease, and the LED lamp of 3 ~ 10W is arranged on the aluminium base, the small end of reflector is over against the light-emitting area of LED lamp, and be fixed on the radiator, LED lamp and reflector consist of single lamp group, and described single lamp group has one group at least.
Further, the length of described reflector is 150 ~ 165 millimeters, and opening diameter is 70 ~ 90 millimeters.
Further, the reflecting surface of described reflector adopts Bezier, and its parameter of curve is: weight (W): 0.5 ~ 0.7, size (S): 24 ~ 25, back size (R): 39 ~ 41, front size (F): 7.5 ~ 8.5.
Further, reflector is made by specular aluminium spinning, and its interior reflective surface minute surface is made oxidation processes.
Compared with prior art, the beneficial effects of the utility model show:
One, light efficiency is high, energy-conservation, the light fixture of a 5W, and at 200 meters irradiation distance, spot diameter is 8 meters, center illumination is 3.1LUX, can replace traditional searchlighting light fixture of 20W.
Two, adopt special design, 500 meters of projections apart from the time, hot spot still assembles, loose, the brightness of light beam is high.
Three, the utility model long service life can be used 30000 hours approximately, and not contain any harmful substance, can not pollute environment.
Description of drawings
Fig. 1 is the structural representation of utility model;
Fig. 2 is single Lamp cup constitutional diagram;
Fig. 3 is the square searchlight that 8 Lamp cups are combined into 40W
The curve of light distribution of Fig. 4 searchlight;
Reference numeral is: 1 is housing for cover glass, 11 for Lamp cup tightens up plate, 9 for protection pressing plate, 10 for seal gasket, 8 for sealing ring, 7 for driving power, 6 for reflector, 5 for radiator, 4 for aluminium base, 3 for LED lamp, 2.
The specific embodiment
The utility model will be further described below in conjunction with the drawings and the specific embodiments.
A kind of LED searchlight, comprise driving power 5, housing 11, the LED lamp 1, reflector, radiator, the aluminium base that also comprise 3 ~ 10W, described aluminium base 2 is fixed on the radiator 3 through heat-conducting silicone grease, the LED lamp of 3 ~ 10W is arranged on the aluminium base 2, and the small end of reflector is over against the light-emitting area of LED lamp, and is fixed on the radiator, LED lamp 1 consists of single lamp group with reflector 4, and described single lamp group has one group at least.The LED searchlight comprises that also Lamp cup tightens up plate, cover glass, cover glass pressing plate; Described Lamp cup tightens up plate and aluminium base tightly is clamped in reflector middle; it is cover glass 10, protection pressing plate 9 successively that Lamp cup tightens up plate 8 outsides; Lamp cup tightens up plate, cover glass, protection pressing plate formation frame; and be installed on the circular shell lamp box that consists of sealing with aluminium base; single lamp group is installed in the lamp box, and lamp box can be square or circular.It is not damaged for the protection of glass that the cover glass two ends also are provided with seal gasket 7.
Installation process of the present utility model: first heat-conducting silicone grease is coated at the aluminium base back side, then be fixed on the radiator, the power line of light fixture is passed radiator, be connected with the LED driving power.With the microcephaly of reflector, behind the center of aligning LED light-emitting area, reflector is fixed on the radiator.According to the distance of searchlight needs irradiation, selection needs the LED searchlight of the present utility model of combination to adopt the quantity of reflector.And with these reflectors according to required shape, be fixed on the radiator, be combined into the LED searchlight of a power demand.
Embodiment
According to the distance of searchlight needs irradiation, calculate the general power of light fixture.Take irradiation distance as 200 meters as example: at 200 meters irradiation distance, spot diameter is 8 meters, and the center illumination of single lamp is 3.1LUX, if think clearly object observing, then the hot spot minimal illumination should be 24LUX.With the center illumination of required illumination divided by single lamp, can calculate the number of required single lamp.
In conjunction with shown in Figure 3, this example needs 8 single lamps be combined into a searchlight 200 meters distance, can satisfy instructions for use.At first according to environment for use and the requirement of light fixture, determine that lamp housing is circle or rectangle.Then determine the opening size of lamp housing.Lamp housing should be included in 8 Lamp cups within its profile, so the general power of this routine searchlight is 5W * 8=40W.
Select the radiator that matches with the lamp housing size.Determine the size of lamp housing according to the size of 8 reflectors.After silicone grease is coated at the back side of LED aluminium base, LED is fixed on the radiator, then with the centrally aligned of reflector and LED, with lamp housing reflector is fixed.
The utility model lamp can be widely used in the use occasion of headstock, landscape light in city, stage illumination, lighting and other long distance illumination of large-scale square, physical culture place, train.
The above has carried out exemplary description to the specific embodiment of utility model by reference to the accompanying drawings, and obviously the utility model is not limited to this, and the various remodeling that carry out in the utility model scope all do not exceed protection domain of the present utility model.
