PURPOSE: A solid state lighting apparatus is provided to replace only a lamp cover with an optical unit, thereby saving manufacturing costs. CONSTITUTION: A solid state lighting apparatus comprises a support object, a solid state lighting source, and a lamp cover(10). Light emitted from the solid state lighting apparatus passes the lamp cover and is irradiated to an object. The lamp cover is integrated with an optical unit(101). The optical unit varies the distribution of optical fields. |
