It solves the problems of bad brightness and narrow projecting range, provides a LED lighting device which can effectively increase the projecting angle of light resource and improve the brightness.
Description
Technical field
The utility model relates to a kind of LED (light emitting diode) lighting device, relates in particular to a kind of LED lighting device that increases the light source projects angle, can increase brightness effects simultaneously.
Background technology
The domestic lighting light fixture generally all adopts osram lamp, and the LED luminescence component is popularized gradually because of energy-conservation, long service life, stabilized intensity now.When being distinguished with regard to two kinds of light-emitting modes, the irradiation of its light source of tradition osram lamp is fan-shaped mode, though and the LED bulb has bright projection source, very big with traditional tungsten filament difference, mainly,, illumination range popularizes thereby having limitation to influence it with linear fashion projection source effect.
The light source characteristic of LED light emitting diode is: luminous angle heals small light source will be brighter, otherwise angle more then brightness is darker, can't reach the light source of approximate bulb fan shape, also because of the shortcoming of LED angle illumination deficiency, have only from structure and improve, just may enlarge range of exposures and brightness.
In addition, the heating of great power LED luminous tube also influences its service life.
Summary of the invention
Technical problem: exist bright inadequately and projection scope problem widely inadequately in order to solve on the light source projects effect, the utility model provides a kind of can effectively increase integrated light source crevice projection angle scope, also reaches the LED lighting device of bright more effect simultaneously.
Technical scheme: to achieve these goals, LED matrix of the present utility model, adopt single lamp that reverberation bowl is arranged, carry out the solid combination of LED lamp at a plurality of faces, promptly install by screwed socket, handle, radiator, great power LED light emitting diode, reverberation bowl lampshade, constant-current drive circuit, intelligent fan, bonnet and formed; Wherein, the great power LED light emitting diode is arranged on the radiator, the reverberation bowl lampshade is enclosed within the outside of radiator, the great power LED light emitting diode is arranged in each the little reverberation bowl on the reverberation bowl lampshade, bonnet is fixed on the back side of radiator, the side of radiator is fixed on the handle, and screwed socket is fixed on the outer end of handle.
Install the intelligent micro fan additional at the back side of radiator, to increase radiating effect.Described great power LED light emitting diode is driven by constant-current drive circuit.Described great power LED light emitting diode is multiaspect and arranges on radiator.Keep more high strength thereby the projection scope that makes light is identical with traditional tungsten filament.In addition, force cooling to guarantee the long-life of luminous tube operate as normal by the heat radiation aluminium and the intelligent micro fan of base.
Beneficial effect: LED lighting device of the present utility model has following advantage:
1, power saving, life-span are long.
2, can use for a long time, temperature is in constant temperature.
3, brightness of illumination is fan shape, and range of exposures approaches conventional bulb.
4, improve that original LED bulb angle is little, the shortcoming of the broad deficiency of brightness.
5, irradiated area is wide, and don't the thorn eyes.
Description of drawings
Fig. 1 is a contour structures schematic diagram of the present utility model.
Fig. 2 is the deployed configuration schematic diagram of the utility model each several part.Have among the figure: screwed socket 1, handle 2, radiator 3, great power LED light emitting diode 4, reverberation bowl lampshade 5, bonnet 6.
The specific embodiment
Describe structure of the present utility model, function in detail below in conjunction with accompanying drawing:
Great power LED light emitting diode 4 is arranged on the radiator 3, reverberation bowl lampshade 5 is enclosed within the outside of radiator 3, great power LED light emitting diode 4 is arranged in each the little reverberation bowl on the reverberation bowl lampshade 5, bonnet 6 is fixed on the back side of radiator 3, the side of radiator 3 is fixed on the handle 2, and screwed socket 1 is fixed on the outer end of handle 2.Install the intelligent micro fan additional at the back side of radiator 3, to increase radiating effect.Described great power LED light emitting diode 4 is driven by constant-current drive circuit.Described great power LED light emitting diode 4 is multiaspect and arranges on radiator 3.
As shown in Figure 2, the utility model is a kind of high-power LED lighting device, its primary structure is: press 49 LED luminous tubes of grouping Boulez on 7 faces of aluminium radiator 3, be fan-shaped outside projection source by reverberation bowl lampshade 5 from 7 different faces (front, the left side, lower-left face, the right side, bottom right face, front, preceding below) then, thereby under the situation of the light intensity that guarantees the LED lamp, enlarged the scope of irradiation again.Power supply passes handle 2 by screwed socket 1 and receives on the constant-current drive circuit at the back side of aluminium radiator 3, and " lights " grouping LED by this drive circuit.In addition,, install the intelligent micro fan additional, the great power LED operate as normal is not generated heat, guaranteed the long-life characteristics of product at the back side of aluminium radiator 3 in order to increase radiating effect.At last bonnet 6 is docked driving fit with reverberation bowl lampshade 5, prevent that the dust foreign material from entering, make device become as a whole.The length and width of plant bulk etc. are close in golden section proportion, and the integral product moulding meets practical and attractive characteristics.
