Abstract: A lens module with an optical axis passing therethrough from an object side to an image side includes a lens housing and two lenses disposed in the lens housing. The first lens has a first refactive portion and a first positioning portion encircling the first refractive portion. A first mating structure is formed on the image side surface of the first positioning portion and molded with the first refractive portion as a single integral. The second lens has a second refractive portion and a second positioning portion encircling the second refractive portion. A second mating structure is formed on the object side surface of the second positioning portion and molded with the second refractive portion as a single integral. The mating structures are engaged to align the lenses along the optical axis, and the refractive portions are coaxial with each other and have the axis as the optical axis.

Abstract: A lens module with an optical axis passing therethrough from an object side to an image side includes a lens housing and two lenses disposed in the lens housing. The first lens has a first refract portion and a first positioning portion encircling the first refract portion. A first jointing structure is formed on the image side surface of the first positioning portion and molded with the first refract portion as a single integral. The second lens has a second refract portion and a second positioning portion encircling the second refract portion. A second jointing structure is formed on the object side surface of the second positioning portion and molded with the second refract portion as a single integral. The jointing structures are engaged to align the lenses along the optical axis, and the refract portions are coaxial with each other and have the axis as the optical axis.

Abstract: A multipurpose gas light including a bracket mounted on the gas can to hold a glass shield around the lamp head and an annular supporting member above the lamp head, a heat shield for covering on the annular supporting member to shield the heat, a container for mounting on the annular supporting member for cooking food after the removable of the heat shield, a container cover for covering the container, and a container cover holder fastened to the gas can at the top for holding the container cover at any of a series of tilted positions to reflect the light of the lamp head in the desired direction by its inside reflecting surface.
