Abstract
A lighting device includes a housing including a power connection hole, at least one light source module disposed on a lower surface of the housing, and a front cover coupled to the housing to define a space in which the light source module is located. The front cover transmits light generated by the light source module. The light source module includes a support protrusion supported by the front cover. The front cover presses the support protrusion when the front cover is coupled to the housing.
Claims18
A lighting device comprising:
- a housing having a power connection hole therein;
- at least one light source module disposed at a lower surface of the housing, the light source module including a support protrusion;
- a front cover coupled to the housing to define a space in which the light source module is located, the front cover configured to permit light generated by the light source module to pass therethrough;
- a power unit spaced apart from the housing, the power unit configured to supply power to the light source module;
- a connection unit connecting the housing to the power unit, the connection unit including:
- a cable hole through which a cable is configured to pass;
- and
- a connection body surrounding the cable hole;
- and
- a light source fixing unit to fix the light source module to the connection unit, the light source fixing unit including:
- at least one light source fixing groove provided on the connection body and recessed in a direction extending outwardly of the cable hole;
- and
- a light source fixing protrusion provided on the light source module and receivable within the light source fixing groove,
- wherein the front cover presses against the support protrusion when the front cover is coupled to the housing to support the light source module, and
- wherein a portion of the connection body is inserted into the power connection hole in the housing.
