Abstract
A module array includes a light emitting device module. The light emitting device module includes a light source unit, a body provided at one surface thereof with a seat on which the light source unit is seated, a plurality of radiation fins disposed on the other surface of the body opposite to one surface of the body, and an air hole perforated in the body from the seat to the radiation fins for the flow of air.
Claims15
A module array comprising first and second light emitting device modules arranged adjacent to one another, each of the light emitting device modules comprising:
- a body having a first side and a second side opposite to the first side;
- a light source unit located at the first side of the body;
- a plurality of radiation fins located at the second side of the body;
- and
- an air hole perforated in the body and extending from the first side of the body to the second side of the body for the flow of air therethrough,
- wherein an air flow passage is defined between the first and second light emitting device modules to extend from the first side to the second side for the flow of air,
- wherein the air flow passage is defined between the bodies of the first and second light emitting device modules,
- wherein side surfaces of the bodies of the first and second light emitting device modules define a portion of the inner peripheral surface of the air flow passage, and
- further comprising at least two connection members configured to connect the bodies of the first and second light emitting device modules,
- wherein the two connection members are spaced apart from each other, and
- wherein side surfaces of the two connection members and the side surfaces of the bodies of the first and second light emitting device modules define the inner peripheral surface of the air flow passage.

A module array comprising first and second light emitting device modules arranged adjacent to one another, each of the light emitting device modules comprising:
- a body having a lower side and an upper side opposite to the lower side;
- a light source unit located at the lower side of the body;
- a plurality of radiation fins located at the upper side of the body;
- and
- a first passive airflow promotion channel extending through the body from the lower side of the body to the upper side of the body, the first passive airflow promotion channel being configured such that rising air heated by the light source unit at the lower side of the body is induced into the first passive airflow promotion channel for passage therethrough to a location at the upper side of the body,
- wherein a second passive airflow promotion channel is defined between the first and second light emitting device modules, the second passive airflow promotion channel being configured such that rising air heated by the light source unit at the lower side of the bodies is induced into the second passive airflow promotion channel for passage therethrough to a location at the upper side of the bodies, and
- wherein the body of the first light emitting device module includes a first side wall having a first recessed portion directed inwardly of the first side wall, the first recessed portion defining a first portion of the inner peripheral surface of the second passive airflow promotion channel.

- and
- an air guide located at the upper side of the body and extending in a direction away from the upper side of the body, the air guide being in communication with the air hole to guide the flow of air therethrough,
- wherein the light source unit includes:
- a board located at the upper side of the body;
- a plurality of light emitting devices disposed on the board;
- a board hole extending through the board, the board hole being in communication with the air hole;
- a plurality of lenses configured to shield the light emitting devices and to refract light emitted from the light emitting devices;
- a lens cover supporting the lenses, the lens cover having a shape generally corresponding to a shape of the board;
- and
- a cover hole extending through the lens cover, the cover hole being in communication with the air hole.
