The utility model content

Because the disappearance of prior art, main purpose of the present utility model is to provide a kind of LED lighting device, its LED light emitting diode that is provided with on the pedestal throws to the reflecting surface of nonmetal white reflection sheet, principle with the light source reflection, order was point-like and direct light source originally, because of the effect of reflection, and be planar and softer light source.

For reaching above-mentioned purpose, the utility model proposes a kind of LED lighting device, it comprises:

One nonmetal white reflection sheet, it has the reflecting surface of a curved arc indent;

One support plate is arranged on the pedestal, is equiped with the LED light emitting diode on it;

One pedestal is arranged at the place ahead of the reflecting surface of nonmetal white reflection sheet, and the direction to reflecting surface on it is equiped with support plate;

At least one light emitting diode, it is arranged on the support plate;

Preferably, this pedestal is arranged at the place ahead of the reflecting surface of nonmetal white reflection sheet.

Preferably, this LED lighting device can be single individual enforcement, and also denumerable tool is implemented side by side.

Preferably, this LED lighting device can be the light source of street lamp, ceiling Recessed light, pendent lamp, table lamp, flashlight etc.

Preferably, this support plate can be offered hole and makes radiating efficiency more promote on its surface.

Preferably, this pedestal can adopt aluminium matter.

Preferably, this pedestal can be done the processing of aluminium oxide misfit thing on its surface, make pedestal become porous pledge spare, increases area of dissipation, makes radiating efficiency more promote.

The specific embodiment

For making your juror further understanding and approval be arranged for structure purpose of the present utility model and effect, hereinafter with reference to the graphic the utility model of describing of enclosing for reaching employed technological means of purpose and effect, and following graphic cited embodiment only is an aid illustration, your understand in order to juror, but that the technological means of this case is not limited to is cited graphic.

At first, see also Fig. 2 and Fig. 3, Fig. 4, shown in Figure 5, a kind of LED lighting device of the present utility model, it comprises a nonmetal white reflection sheet 11, side can have the reflecting surface 111 of a curved arc indent within it; One pedestal 3 towards the reflecting surface 111 direction places of nonmetal white reflection sheet 11, can establish a storage tank 33 on the pedestal 3, but its mat location structure 321 is equiped with a support plate 32, is equiped with LED light emitting diode 2 on the support plate 32 on pedestal 3; Also can offer hole 320 on the support plate 32 to increase radiating effect, location structure 321 can be location structures such as the solid mode of spiral shell, holding mode, button system mode.

LED light emitting diode 2, pedestal 3 are arranged at the place, reflecting surface 111 the place aheads of nonmetal white reflection sheet 11, and pedestal 3 can make LED light emitting diode 2 be located in position; At least one LED light emitting diode 2, its mat support plate 32 location be arranged at pedestal 3 on; Structure by this, a kind of LED lighting device of the present utility model, be installed on the pedestal 3 reflecting surface 111 direction places by its light source led light emitting diode 2 towards nonmetal white reflection sheet 11, LED light emitting diode 2 can be one or more, and pedestal 3 is arranged at the place, reflecting surface 111 the place aheads of nonmetal white reflection sheet 11; See also shown in Figure 5, when the LED light emitting diode 2 on this pedestal 3 is lighted, the light 21 of its light source is to reflecting surface 111 projections of nonmetal white reflection sheet 11, refraction action by reflecting surface 111, order was point-like and direct light source originally, because of the effect of reflection, and be planar and softer light source, and make lighting device obtain more comfortable soft visual experience.

Other is the person, because pedestal 3 is arranged at the place, reflecting surface 111 the place aheads of nonmetal white reflection sheet 11, the heat of being conducted when lighting by LED light emitting diode 2, its heat radiation is good from more generally having the LED lighting device now, right the utility model more can be to impose on the surface of pedestal 3 processing of aluminium oxide misfit thing 31, makes pedestal become porous pledge spare, increases area of dissipation, make radiating efficiency more promote, and help the heat radiation of LED light emitting diode 2.

Therefore, the utility model is as the general illumination device, and it can hold the lighting device of long rectangle as shown in Figure 2, also can hold the lighting device of circle as shown in Figure 6, or is long rectangle lighting device arranged side by side as shown in Figure 7; And the light source that is installed in Recessed light on lamp socket or the ceiling, pendent lamp, street lamp, table lamp etc. on using is installed, and can obtain softer light source effect.

In sum, the utility model is a kind of LED lighting device, and with the principle of light source reflection, order was point-like and direct light source originally, because of the effect of reflection, and was planar and softer light source; And cooperate the processing of aluminium oxide misfit thing on the hole offered on the support plate surface and the pedestal surface, and make pedestal become porous pledge spare, increase area of dissipation, make radiating efficiency more promote.It is simple in structure, easy to assembly, low cost of manufacture, light and handy, can improve the shortcoming of existing lighting device really and can promote effect, has patentability.

The above person, it only is preferred embodiment of the present utility model, when can not with restriction scope of the present utility model, promptly the equalization of being done according to the utility model claim generally changes and modifies, will not lose main idea of the present utility model place, also do not break away from spirit and scope of the present utility model, the former capital should be considered as further enforcement situation of the present utility model.
