Particularly, described lenticule circular array or rectangular array on described first lens face.
Particularly, described annular array is helical form annular array.
Particularly, described lenticule is small convex lens or concavees lens.
Particularly, described lenticular spherical radius is 3 ~ 15mm.
Preferably, described lenticular spherical radius is 8mm.
Particularly, the cross section of described cannelure is triangle.
Particularly, described reflection shield is bowl-type.
Particularly, described reflection shield is spliced by some trapezoidal reflecting plates.
Particularly, described light source is LED lamp.
Light fixture of the present invention is by arranging some equally distributed lenticules on the first lens face at lens, the second lens face at lens is carved some ascending concentric annular grooves, when the first lens of lens is during facing to light source, can realize floodlighting, when the second lens face of lens is during towards light source, can realize spotlighting, thereby can make light fixture adapt to the demand of different occasions to illumination.

The specific embodiment
Below in conjunction with the accompanying drawing in the embodiment of the present invention, the technical scheme in the embodiment of the present invention is clearly and completely described.
As shown in Fig. 1 ~ Fig. 3, the embodiment of the present invention provides a kind of can optically focused and the light fixture of floodlight, comprise lamp holder (not shown) and be located at the reflection shield 1 in lamp holder, in reflection shield 1, be provided with light source 2, lamp base front end is also provided with lens 3 that are oppositely arranged with reflection shield 1, lens 3 comprise first lens face 31 parallel to each other and that be oppositely arranged and the second lens face 32
Wherein, reflection shield 1 is bowl-type, and reflection shield 1 is spliced by some trapezoidal reflecting plates 11, and reflection shield 1 plays reflection and converges the effect of light.
Wherein, light source 2 is LED lamp, and LED light fixture has that volume is little, power consumption is low, the advantage of high brightness, low in calories, long service life, safety and environmental protection.
Wherein, first lens face 31 is sphere, first lens face 31 is provided with some equally distributed lenticules 311, lenticule 311 is circular array or rectangular array on first lens face 31, in this specific embodiment, lenticule 311 annular array in the shape of a spiral on first lens face 31, i.e. lenticule 311 circular array on first lens face 31 not only, and also lenticule 311 is also combined to form a helicoidal structure.Lenticule 311 is small convex lens or concavees lens, and in this specific embodiment, lenticule 311 is small concavees lens, and the spherical radius of lenticule 311 is 3 ~ 15mm, and spherical radius the best of lenticule 311 is 8mm.
Wherein, the second lens face 32 is carved with some ascending concentric annular grooves 321, and the cross section of cannelure 321 is triangle, and to have the shape of one side of concentric annular groove identical for the shape of the second lens face 32 and Fresnel Lenses.
As Fig. 2, 3, 4, shown in 5, when needs light fixture carries out floodlighting, first by the first lens face 31 of lens 3 towards light source 2, the light part that light source 2 sends is directly injected first lens face 31, another part is injected first lens face 31 after reflection shield 1 reflection, light produces refraction at lenticule 311 places of first lens face 31, when light is during from the second lens face 32 outgoing of lens 3, light produces refraction again at cannelure 321 places of the second lens face 32, light is successively after twice refraction of first lens face 31 and the second lens face 32, light is dispersed to surrounding, thereby realize the object of floodlighting.
As Fig. 2, 3, 6, shown in 7, when needs light fixture carries out spotlighting, first by the second lens face 32 of lens 3 towards light source 2, the light part that light source 2 sends is directly injected the second lens face 32, another part is injected the second lens face 32 after reflection shield 1 reflection, light produces refraction at cannelure 321 places of the second lens face 32, when light is during from first lens face 31 outgoing of lens 3, light produces refraction again at lenticule 311 places of first lens face 31, light is successively after twice refraction of the second lens face 32 and first lens face 31, light converges to center, thereby realize the object of spotlighting.
In sum, light fixture of the present invention is by arranging some equally distributed lenticules 311 on the first lens face 31 at lens 3, second lens face some ascending concentric annular grooves 321 at 32 quarter at lens 3, when the first lens face 31 of lens 3 is during towards light source 2, can realize floodlighting, when the second lens face 21 of lens 3 is during towards light source 2, can realize spotlighting, thereby can make light fixture adapt to the demand of different occasions to illumination.
The above is the preferred embodiment of the present invention; it should be pointed out that for those skilled in the art, under the premise without departing from the principles of the invention; can also make some improvements and modifications, these improvements and modifications are also considered as protection scope of the present invention.
