Abstract
The invention discloses a lamp and a reflector thereof. The lamp comprises a light source and a lamp reflector. The lamp reflector is formed by 180-degree rotation of two symmetrical buses around the symmetry axis. A plurality of reflection rings connected along the axial direction of the lamp reflector successively are arranged on the inner surface of the lamp reflector and are composed of a plurality of convex cambered surfaces which are connected successively along the circumference of the inner surface. Shapes of the convex cambered surfaces of the same reflection ring are different. The numbers of the convex cambered surfaces contained by the reflection rings are identical. Edges of each of the convex cambered surfaces comprise two transverse edges and two longitudinal edges, the longitudinal edges are arcs, and the convex cambered surfaces are formed by sweeping of the longitudinal edges along the transverse edges. The radii of longitudinal edges of all convex cambered surfaces are identical. For the convex cambered surfaces with longitudinal edges of different diameters, the reflection light angles are different if the incident angles are different, initial light distribution can be adjusted by changing the radii of the longitudinal edges, and different-angle light distribution effects can be formed without adjusting of the external structure of the lamp reflector and bus shapes.

Detailed description of the invention
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.
Referring to Fig. 1 to Fig. 3, a kind of light fixture that the preferred embodiment of the present invention provides, comprises lamp reflector 1 and light source 2.Lamp reflector 1 is formed around its symmetry axis Rotate 180 degree by the bus of two symmetries, and the both ends open of lamp reflector 1, is respectively light inputting end and bright dipping end, and light inputting end to bright dipping end diameter increases gradually.Light source 2 is arranged on lamp reflector 1 light inputting end.The bus of lamp reflector 1 is straight line or camber line, and the shape of generatrix of lamp reflector 1 can be determined the initial luminous intensity distribution of light fixture.
The inner surface 10 of lamp reflector 1 comprises the multiple reflexed light rings 11 that connect successively along the axis direction of lamp reflector 1, and reflexed light ring 11 is made up of the multiple convex globoidals 110 that circumferentially connect successively along inner surface 10; The shape size of the convex globoidal 110 of same reflexed light ring 11 is identical; Convex globoidal 110 numbers that each reflexed light ring 11 comprises are identical.Multiple convex globoidals 110 form miniature compound eye, and whole reflector forms miniature compound eye reflector.In order to reach best compound eye effect, the number of reflexed light ring 11 is 10 ~ 16, the number of the convex globoidal 110 that each reflexed light ring 11 comprises is 50 ~ 70, in the present embodiment, the number of reflexed light ring 11 is 13, each reflexed light ring 11 comprises 60 convex globoidals 110, adds up to 13 × 60 convex globoidals 110.The light that light source 2 sends is diffused in target face after reflecting by convex globoidal 110, overlapping in target face finally by the light of crossing all convex globoidals 110, forms evenly soft illuminating effect.
In order to make light distribution angle be convenient to control, the bright dipping end diameter d 1 of inner surface 10 is 1.5 ~ 2.5 times of light inputting end diameter d 2, and the bright dipping end diameter d 1 of described inner surface 10 is lamp reflector 12 ~ 3 times of h along the axial length.In the present embodiment, the light inputting end diameter d 2 of inner surface 10 is 27.53mm, and bright dipping end diameter d 1 is 55.9mm, and length h is vertically 22.3mm, and volume is little, is convenient to configure on portable lamp, is beneficial to the overall construction design of light fixture simultaneously.
