Abstract: A lens and a lamp using the same are provided. The lamp includes a lampshade, a base, a lens and a light emitting diode (LED). The lampshade and the lens are assembled on the base, wherein the lens is located in the lampshade. The lens has an accommodating portion, a first light exiting surface and a second light exiting surface. The first light exiting surface is located above the accommodating portion, and the second light exiting surface surrounds the first light exiting surface and located outside the accommodating portion. The first and second light exiting surfaces are concaves. The LED is disposed in the accommodating portion of the lens.

Abstract: An optical lens module includes a lens body and a transflective unit. The lens body has a central axis, and has an incident surface, a refractive surface and a side refractive surface. The refractive surface includes a refractive arc-surface and at least one auxiliary refractive surface on the side of the refractive arc-surface. The transflective unit covers the refractive surface. The light incident on the refractive surface is diverged away from the central axis and the diverged light on the transflective unit is partially through the transflective unit and partially reflected to travel out of the lens body through the side refractive surface. The light incident on the transflective unit is reflected to travel out of the lens body through the side refractive surface. The light incident on the side refractive surface is refracted out of the lens body through the side refractive surface.

Abstract: A lens structure adapted for guiding a light from a light source to a plurality of directions is provided. The lens structure includes a base, a pillar, and an umbrella-shaped body. The base has a containing pit adapted for containing the light source. The pillar is connected to the base. The pillar has a central axis and a first curved surface, in which the first curved surface surrounds the central axis symmetrically. The umbrella-shaped body is connected to the pillar and has a second curved surface and a third curved surface surrounding the central axis symmetrically. The second and the third curved surfaces are located on a top portion of the umbrella-shaped body and next to each other.

Abstract: A lighting apparatus includes a base having a connection surface thereon; a transparent enclosure mounted on the connection surface, wherein the transparent enclosure and the connection surface define a receiving compartment; a support member disposed on the connection surface and within the receiving compartment, wherein the support member includes a bottom surface connected to the connection surface and a plurality of first mounting side-surfaces extending from the flanges of the bottom surface; and a lighting unit including at least three first lighting devices, and the first lighting devices respectively mounted on the first mounting side-surfaces, wherein each of the first lighting devices has a light axis, the connection surface has a normal axis, and a first included angle defined between the light axis of one of the first lighting devices and the normal axis of the connection surface is at least larger than 30 degrees.
