Claim 10:
11. A lamp, comprising:
at least two illumination parts;
a lamp body having an upper portion and a lower portion corresponding to the upper portion, wherein the lamp body comprises:
a photopermeable and circular surrounding wall having an accommodation space therein;
an opaque partition member dividing the accommodation space of the surrounding wall to form at least two optical cavities extending between the upper portion and the lower portion of the lamp body, wherein the at least two illumination parts are arranged to generate lights in the at least two optical cavities respectively, wherein the partition member is configured in such a manner that the light generated by one of the at least two illumination parts in one of the at least two optical cavities is only allowed radiating to outside through the surround wall and prevents from passing through the partition member to enter another one of the at least two optical cavities, wherein the partition member comprises:
a circular spacer body arranged in the accommodation space of the surrounding wall, wherein a circular cross section of the spacer body and a circular cross section of the surrounding wall are concentrically arranged; and
at least two spacer boards respectively extended between an outer wall of the spacer body and an inner wall of the surrounding wall in a spaced manner with respect to each other, wherein two ends of each of the at least two spacer boards and the spacer body are respectively extended to the upper portion and the lower portion of the lamp body so as to define the at least two optical cavities between the surrounding wall and the spacer body and at least two spacer boards respectively, wherein an outer edge of each of the at least two spacer boards is extended to the inner wall of the surrounding wall in such a manner that a radian of an outer edge of each of the at least two spacer boards is consistent to a radian of the inner wall of the surrounding wall, such that when the one of the at least two illumination parts arranged in one of the at least two optical cavities generates the light, the spacer body and the at least two spacer boards of the partition member block the light from entering the another one of the at least two optical cavities, wherein an outer wall of the spacer body and outer walls of the at least two spacer boards have a reflection layer for reflecting the lights generated by the at least two illumination parts to pass through the surrounding wall and radiate to the outside;

an upper cover body arranged on the upper portion configured to close upper openings of the at least two optical cavities;
a lower cover body arranged on the lower portion configured to close lower openings of the at least two optical cavities; and
a conical oblique inner wall obliquely extended from the spacer body towards an edge direction of the upper cover body upwardly and outwardly, wherein the at least two illumination parts face towards the oblique inner wall such that the lights generated by the at least two illumination parts is able to be reflected by the oblique inner wall to pass through the surrounding wall and radiate to the outside; and

a circuit board arranged in the lower cover body, wherein the at least two illumination parts are arranged on the circuit board such that the two illumination parts are held on the lower portion of the lamp body to generate the lights in the at least two optical cavities respectively.
