A chemical luminescence apparatus comprises a tube container, having an open top, which contains a first chemical luminous liquid and an ampul which in turn contains a second chemical luminous liquid, chemically reactive with the first chemical luminous liquid for producing a luminescent reaction product, wherein the open top of the tube container is hermetically sealed by a cap at a lower portion of such cap. At the upper surface of the cap is formed a groove to which upstanding walls of a mount member, a stand member, or a coupler are detachably mounted, thereby enabling not only wide range uses of the apparatus, but also enabling maintenance operation, such as exchange of parts, to be easily performed.
