The specific embodiment

Provide the utility model preferred embodiment below in conjunction with accompanying drawing, to describe the technical solution of the utility model in detail.

LED floodlight of the present utility model is installed on the lamp body by at least two group LED lighting sources and forms, and every group of LED lighting source can only be provided with a LED lighting source, and a plurality of LED lighting sources also can be set, and is determined on a case-by-case basis.Unlike the prior art be, in the LED floodlight of the present utility model, each shooting angle of organizing the LED lighting source is to increase (or reducing) successively, this angle of emergence can be selected from any two or more the combination in narrow angle, Zhong Jiao, Kuan Jiao, the wide-angle, wherein, narrow angle is below 25 °, and middle angle is 25 °～45 °, wide angle is 45 °～75 °, and wide-angle is more than 75 °.

Referring to Fig. 3, it is the LED floodlight structural representation of the utility model one embodiment, and described LED floodlight comprises four groups of LED lighting sources, be arranged on the lamp body 10 with suitable spacing, and in present embodiment, be spaced set.Each LED lighting source 30 comprises LED particle 31 and optical lens 32, LED particle 31 is used to produce illumination light, optical lens 32 is used for determining the shooting angle of illumination light, promptly by adopting different optical lens 32 to realize the different angles of emergence, the A among the figure, B, C, D are respectively applied for the angle of emergence of four groups of lens of sign to present embodiment.In order to reach the effect of uniform irradiation, the angle of emergence of four groups of illuminating lamps can set gradually by from small to large order and be narrow angle below 25 °, and is preferred, angle A=15 ° ± 10 °; 25 °～45 ° at middle angle, preferred, angle B=35 ° ± 10 °; 45 °～75 ° at wide angle, preferred, angle C=60 ° ± 15 °; Wide-angle is more than 75 °, and is preferred, angle D=95 ° ± 20 °.

In other embodiment, the LED floodlight also can adopt four groups of above LED lighting sources, only need satisfy the condition that the angle of emergence increases (or reducing) successively when choosing optical lens gets final product, for example in six groups of LED lighting sources one group of narrow angle, two groups of Zhong Jiao, two groups of Kuan Jiao and one group of wide-angle can be arranged, but wherein two groups of Zhong Jiao and two groups of angle differences that wide angle is chosen, increase the light fixture of (or reducing) successively thereby constitute the angle of emergence, reach the effect of even illumination.Other group LED lighting sources of numbers and shooting angle thereof the scheme of choosing can the rest may be inferred, so do not enumerate one by one at this.

The bottom of lamp body 10 shown in Figure 3 is plate, is not damaged in order to protect illuminating lamp better, and lamp body also can be made and to have sidewall, as shown in Figure 4.Block the light that sends than wide-angle group LED lighting source for fear of the lamp body sidewall, can step 40 be set, raise installation, thereby can avoid interference of light in the bottom of bigger that group LED lighting source of the angle of emergence.

See also Fig. 5, it is the use schematic diagram of the utility model LED floodlight.When adopting LED floodlight of the present utility model to carry out the metope illumination, lamp body can be obliquely installed slightly, and one group of LED lighting source of angle of emergence maximum is arranged on the position of close metope, like this light that sends from light fixture can uniform irradiation at surface of wall.

Referring to Fig. 6, it has shown and adopts LED floodlight shown in Figure 5 to shine the illuminating effect schematic diagram that one 3 meters high 0.8 meter wide metopes obtain, the rectangle frame of bottom is represented light fixture among the figure, represent 36 LED lighting sources by 4 * 9 small circles of arranging in the rectangle frame, promptly 4 groups of LED lighting sources comprise 9 LED lighting sources for every group.Compare with the illuminating effect of existing LED light fixture shown in Figure 2, adopt LED floodlight of the present utility model to throw light on, its body of wall is subjected to light even, and obviously improve four jiaos of dark spaces of body of wall, and the zone of high brightness is diffused into than large tracts of land, has reached desirable illuminating effect.

In sum, adopt LED floodlight of the present utility model to carry out the place that decorating building illumination, indoor wall illumination and other need evenly throw light on to a plane, can reach better illumination uniformity than prior art, enlarge illumination zone, promote visual effect greatly.

The foregoing description only is illustrative principle of the present utility model and effect thereof, but not is used to limit the utility model.Any those skilled in the art all can be under spirit of the present utility model and category, and the foregoing description is modified and changed.Therefore, rights protection scope of the present utility model should be foundation with the scope of claims.
