Abstract:
A light emitting apparatus including a circuit board (10), at least one light emitting chip (20), an integrated optical cover (30) and a fluorescent layer (40). The light emitting chip (20) is arranged on the circuit board (10). The integrated optical cover (30) has a peripheral wall (31), a top wall (32) and a light guiding post (33). The peripheral wall (31) is arranged around the circuit board (10). The top wall (32) is arranged on the peripheral wall (31). The light guiding post (33) extends from the top wall (32) toward the light emitting chip (20). The light guiding post (33) includes a recess portion (332). The light emitting chip (20) is accommodated in the recess portion (332). The fluorescent layer (40) is arranged between the recess portion (332) and the light emitting chip (20). By using the recess portion (332) and the light emitting chip (20) cooperatively to confine the fluorescent layer (40), the thickness thereof can be controlled to be consistent.
