Abstract
A lighting device may be provided that includes: a light emitting module; a heat sink disposed on the light emitting module; a heat radiating fan disposed on the heat sink; and a housing which receives the light emitting module, the heat sink and the heat radiating fan, and includes an air inlet port and an air outlet port which are separated from each other, and includes a partition separating the air inlet port from the air outlet port, wherein the air inlet port is connected to a space between the heat radiating fan and the housing, and wherein the air outlet port is connected to a space between the heat sink and the heat radiating fan.
Claims20
A lighting device comprising:
- a light emitting module;
- a heat sink disposed on the light emitting module;
- a heat radiating fan disposed on the heat sink;
- and
- a housing which receives the light emitting module, the heat sink and the heat radiating fan, and includes an air inlet port and an air outlet port which are separated from each other, and includes a partition separating the air inlet port from the air outlet port, wherein the air inlet port is connected to a space between the heat radiating fan and the housing, and wherein the air outlet port is connected to a space between the heat sink and the heat radiating fan.
A lighting device comprising:
- a heat sink;
- a light emitting module disposed under the heat sink;
- a heat radiating fan which is disposed on the heat sink and inhales air and emits to the heat sink;
- a driving unit disposed on the heat radiating fan;
- and
- a housing receiving the light emitting module, the heat sink and the heat radiating fan,
- wherein the housing includes a first hole connected between the heat radiating fan and the driving unit and a second hole connected between the heat radiating fan and the heat sink,
- wherein the housing includes a partition separating the first hole from the second hole,
- wherein, by the operation of the heat radiating fan, air having a first temperature is introduced into the first hole and air having a second temperature is emitted to the second hole, and
- wherein the second temperature is higher than the first temperature.
A lighting device comprising:
- a heat sink;
- a light emitting module disposed under the heat sink;
- a heat radiating fan disposed on the heat sink;
- a first case which receives the light emitting module and the heat sink;
- and
- a second case which receives the heat radiating fan and is coupled to the first case,
- wherein the first case includes a first path and a second path, both of which have been formed independently of each other, and a partition separating the first path from the second path,
- wherein the heat radiating fan inhales air introduced through the first path and emits the inhaled air to the heat sink, and
- wherein the heat sink which guides the air emitted from the heat radiating fan to the second path.
