Abstract

The utility model discloses a light-emitting diode (LED) floodlight which comprises an LED luminous element, a lampshade and a light filter. The LED luminous element is arranged in the lampshade, the light filter is arranged on a lampshade opening, and a central light filtering degree of the light filter is different from peripheral light filtering degrees. By means of the technical scheme of the LED floodlight, the light filer is arranged in the front of the LED floodlight, so that light intensity can be appropriately reduced, besides, the light filter can be changed, and different light filters can be changed to meet different lighting requirements according to different positions.

Description

The LED floodlight

Technical field

The utility model relates to a kind of lighting apparatus, more particularly, relates to a kind of LED floodlight.

Background technology

The divergence of beam degree of at present common LED floodlight is bigger, and the position of light source is more shallow.Consider the floor height problem of general house decoration, the installation site of LED floodlight can be too not high.When this LED floodlight was applied to daily finishing, because its position is lower, and the position of light source was more shallow; Therefore often the user can receive direct light stimulation when coming back; Produce dazzle thus, if things go on like this, also can produce more serious eyesight disease; Retinal burn for example, even cause losing one's sight.

The utility model content

The purpose of the utility model aims to provide a kind of LED floodlight, solves the various deficiencies that exist in the prior art.

According to the utility model, a kind of LED floodlight is provided, comprise LED light-emitting component, lampshade and optical filter.Wherein, the LED light-emitting component is arranged at lampshade inside, and optical filter is arranged at the lampshade mouth, and the center optical filtering degree of optical filter is with degree of optical filtering is different all around.

According to an embodiment of the utility model, the center optical filtering degree of optical filter less than around degree of optical filtering.

According to an embodiment of the utility model, the center optical filtering degree of optical filter greater than around degree of optical filtering.

According to an embodiment of the utility model, the lampshade inwall posts reflecting piece.

According to an embodiment of the utility model, the lampshade mouth is provided with the steady pin of being convenient to replace said optical filter.

Adopt the technical scheme of the utility model, before the LED floodlight, optical filter has been set, can suitably reduce light intensity.And the optical filter of the utility model is removable, can change different optical filters and adapt to different daylighting demands according to different positions.

Description of drawings

In the utility model, identical Reference numeral is represented identical characteristic all the time, wherein:

Fig. 1 is the sketch map of the utility model LED floodlight.

Fig. 2 is the sketch map of light path among Fig. 1.

The specific embodiment

Further specify the technical scheme of the utility model below in conjunction with accompanying drawing and embodiment.

Fig. 1 is the sketch map of the utility model LED floodlight.As shown in Figure 1, the LED floodlight of the utility model comprises lampshade 10, LED light-emitting component 11 and optical filter 12.Lampshade 10 is bowl-shape hollow hemisphere, and a plurality of reflecting piece 13 are posted in its inside.LED light-emitting component 11 is arranged at lampshade 10 inside, is positioned near the place, arc top.Optical filter 12 is arranged at the opening part of lampshade 10, promptly bowl-shape the rim of a bowl place, and the center optical filtering degree of optical filter 12 is with degree of optical filtering is different all around.Opening part at lampshade 10; Be to be provided with a plurality of steady pins 14 near bowl-shape the rim of a bowl place; Be used for optical filter 12 is fixed on the opening part of lampshade 10, prevent that optical filter 12 from dropping from the opening part of lampshade 10, the structure of steady pin 14 also can be convenient to the replacing of optical filter 12 simultaneously.

Fig. 2 is the sketch map of light path among Fig. 1.As shown in Figure 2, LED light-emitting component 11 is as light source, to a plurality of direction emission light.Wherein, Part light can directly penetrate optical filter 12; And another part light forms reflection on optical filter 12 surfaces, and reverberation after touching reflecting piece 13 secondary reflection again takes place, and partial reflection light can penetrate optical filter 12 again after reaching certain intensity; And some reverberation on optical filter 12 surfaces secondary reflection again, by that analogy.

In the utility model, optical filter 12 has two kinds of embodiments, the one, center optical filtering degree less than around degree of optical filtering, the 2nd, center optical filtering degree greater than around degree of optical filtering.

For center optical filtering degree less than around the situation of degree of optical filtering, promptly optical filter 12 around part can the elimination more rays, thereby most of light all concentrates on the mid portion of optical filter 12.Floodlight in this case is fit to be installed in the corner in room, do not need too much to around divergent rays, but in the middle of the room throw light.

For center optical filtering degree greater than around the situation of degree of optical filtering, promptly the mid portion of optical filter 12 can the elimination more rays, thus most of light all concentrate on optical filter 12 around part.Floodlight in this case is fit to be installed in the central authorities in room, because close together, should avoid too much light direct projection, and need to around divergent rays.

Those of ordinary skill in the art will be appreciated that above specification only is one or more embodiments among the numerous embodiment of the utility model, and is not the qualification of using the utility model.Any for the above embodiment equalization variation, modification and be equal to technical schemes such as alternative, as long as meet the connotation scope of the utility model, all will drop in the scope that claims of the utility model protect.
