Abstract
A lamp cover includes an array of lenses. Each lens includes an incidence surface for receiving light, and an emitting surface opposite to the incidence surface. One of the incidence surface and the emitting surface is a convex surface. Each lens includes a first end and an opposite second end in a column direction, a third end and an opposite fourth end in a row direction. The lenses in each row, a thickness difference between the first end and the second end of each lens is greater than a thickness difference between the third end and the fourth end thereof. An illumination lamp is also provided in this invention.
Claims18
An illumination lamp comprising:
- at least one lighting member for generating light;
- and
- a light pervious lamp cover arranged spatially corresponding to the lighting member, the lamp cover having a plurality of lenses arranged in columns and rows, each lens comprising an incidence surface facing the at least one lighting member for receiving the light emitted therefrom, and an emitting surface opposite to the incidence surface, one of the incidence surface and the emitting surface being a convex surface, each lens comprising a first end and an opposite second end in the column direction, a third end and an opposite fourth end in the row direction, the lenses in each row, a thickness difference between the first end and the second end of each lens being greater than a thickness difference between the third end and the fourth end thereof.
A lamp cover comprising:
- an array of lenses, an array of lenses, each lens comprising an incidence surface for receiving light, and an emitting surface opposite to the incidence surface, one of the incidence surface and the emitting surface being a convex surface, each lens comprising a first end and an opposite second end in a column direction, a third end and an opposite fourth end in a row direction, the lenses in each row, a thickness difference between the first end and the second end of each lens being greater than a thickness difference between the third end and the fourth end thereof.
An illumination lamp comprising:
- a light source for emitting light;
- and
- a light pervious lamp cover having a plurality of identical lens portions arranged in columns and rows, each lens portion comprising an incidence surface facing the light source for receiving the light emitted therefrom, and an emitting surface opposite to the incidence surface, one of the incidence surface and the emitting surface being a convex surface, each lens comprising a first side surface and an opposite second side surfaces in the column direction, a third side surface and an opposite fourth side surface in the row direction, the third surface having a greater area than that of the fourth side surface, the third surfaces facing toward a same direction.
