摘要:
A light-emitting device, including a mount substrate, at least one light emitting element, a first light transparent member, a second light transparent member and a covering member, is disclosed. The at least one light emitting element is disposed on the mount substrate in a flip-chip manner. The first light transparent member is configured to receive the incident light emitting from the light emitting element, wherein the first light transparent member is formed of an inorganic substance and an inorganic phosphor, and includes a top surface and a first side surface contiguous to the top surface. The second light transparent member is disposed on the top surface of the first light transparent member and is formed of the inorganic substance and contains no the inorganic phosphor, and includes an externally exposed light emission surface and a second side surface contiguous to the externally exposed light emission surface. The covering member comprises a light reflective material and covers at least the first side surface of the first light transparent member and at least the second side surface of the second light transparent member.
