Abstract:
A rotatable illumination device includes a first casing, a light emitting module, a first fixing member and a second fixing member. The first casing has a first rotating portion and a first protruding portion is formed on the first rotating portion. The light emitting module is disposed in the first casing. A first indentation is formed on the first fixing member and the first protruding portion can pass through the first indentation. A second indentation and a second protruding portion are formed on the second fixing member and the first protruding portion can pass through the second indentation. The first and second fixing members are fixed together, and the first and second protruding portions are coplanar. The first protruding portion cooperates with the second protruding portion to limit rotating angle of the first casing.
