A slide rheostat is connected in series between a driving circuit of the LED and the LED. The sliding body and the chute form the slide rheostat.
Description
Technical field
The utility model relates to a kind of LED lighting device.
Background technology
The LED light fixture is widely used, and progressively replaces traditional incandescent lamp and energy-saving fluorescent lamp.The power adjusting of LED light fixture is very convenient and flexible.Be the multiple-pole switch control and regulation to the most frequently used mode of the power adjusting of LED light fixture on the market at present, the different shelves of switch are used for the LED of control varying number, with the adjusting of the power of realizing light fixture.Above-mentioned these light fixtures can realize rotating and shining the adjustment at the elevation angle, but generally do not possess the adjustment of height, in time have the function of certain Height Adjustment, but power can not be adjusted thereupon.The height of light fixture is higher, and the scope of its irradiation is larger, and in the situation of former power, ground illumination can reduce.
The utility model content
The utility model purpose provides a kind of mobile LED lamp, and it has lifting structure, and the corresponding adjustment of reality power in the height of adjusting the LED light fixture is to keep stable illuminance of ground requirement.
In order to solve above-mentioned technical problem, the utility model proposes a kind of mobile LED lamp, comprise lamp stand, lamp socket and LED light fixture, lamp stand is located on the lamp socket, and it also comprises:
Lift and quadrangle crane;
The quadrangle crane comprises movable upper end joint, lower end turning joint and two intermediate active joints between them;
Lift is fixed on the lamp stand, and it is connected with the lower end turning joint of quadrangle crane by elevating lever;
The upper turning joint of quadrangle crane is fixed on the described lamp stand, is equipped with the LED light fixture in two intermediate active joints;
Be provided with chute at lamp stand, lower end turning joint is connected with chute by slide mass, and it is up and down in chute that elevating lever drives slide mass;
Described LED lamp comprises the drive circuit of LED, is in series with a slide rheostat between drive circuit and the LED, and described slide mass and chute form this slide rheostat, and slide mass upwards moves, and the resistance of slide rheostat reduces, and the LED electric current increases; Slide mass is to moving down, and the resistance of slide rheostat increases, and the LED electric current reduces.
Preferably: described lift is screw-threaded shaft elevator, and described elevating lever is leading screw.
Preferably: described slide rheostat is composed in series by a plurality of resistance, and slide mass makes the change in resistance of slide resistor be stepped change when regulating resistance.
The beneficial effects of the utility model:
Compared to existing technology, the utility model has designed a quadrangle crane, this crane has utilized the quadrangle can movable rule, it provides lifting drive by lift, drive the LED light fixture and move up and down, the movement that the LED light fixture can be made is not limited only to axially-movable up and down, can also move radially, therefore the adjustment mode of its illumination is more flexible, and no matter still to reduce the illumination that all can keep ground under the lamp stable in the rising of light fixture.For example, when needing less range of exposures, elevating lever drives light fixture and descends, and this moment, rheostatic resistance increased, and the LED electric current reduces, the power reduction of light fixture; When needing to increase range of exposures, elevating lever drives light fixture and rises, and this moment, rheostatic resistance reduced, and the LED electric current increases, the increase of output power of light fixture; The increase of output power of light fixture and reduce height correlation with LED, their adjustment make the illumination under the lamp keep in balance as far as possible, and the variation of illumination is unlikely to too obviously in the situation illumination zone of light fixture can be changed obviously under stable or the lamp.
