Abstract
An optical semiconductor based illuminating apparatus includes a first unit which is disposed on an upper side of a housing and includes protrusions formed on a lower outer side of an optical member surrounding a semiconductor optical device and having an inclined surface inclined upwards from a lower edge of an optical member; and a second unit which accommodates and holds the first unit, so that it can reduce defect rate, improve assembly efficiency, and has excellent durability.
Claims27
An optical semiconductor based illuminating apparatus, comprising:
- a housing;
- at least one semiconductor optical device disposed on an upper side of the housing;
- an optical member disposed on the upper side of the housing;
- a first unit disposed on a lower outer side of the optical member, the first unit comprising a protrusion extending outwardly from an outer surface of the first unit, the protrusion comprising an inclined surface inclined from a lower edge of the optical member;
- and
- a second unit disposed on the upper side of the housing, the second unit comprising a cutout portion formed in an inner surface thereof,
- wherein the first unit is configured to be inserted into the second unit, and
- wherein the inclined surface of the protrusion is configured to contact a first side of the cutout portion.
An optical semiconductor based illuminating apparatus, comprising:
- a housing;
- at least one semiconductor optical device disposed on a first side of the housing;
- an optical member disposed on the first side of the housing;
- a first unit disposed on a lower side of the optical member, the first unit comprising a protrusion extending towards an outside surface of the illuminating apparatus, the protrusion comprising an inclined surface;
- and
- a second unit disposed on the first side of the housing, the second unit comprising a first groove disposed in an inner surface of the second unit,
- wherein the inclined surface of the protrusion contacts a first side of the first groove.
A light emitting device, comprising:
- a housing;
- a semiconductor device disposed on the housing and configured to emit light;
- an optical member disposed on the housing and configured to receive the emitted light from the semiconductor device;
- a first unit coupled with the optical member and comprising first coupling members;
- and
- a second unit coupled with the housing and comprising second coupling members configured to receive the first coupling members, respectively, the first unit being detachably coupled with the second unit via the first and second coupling members.
