A light source module according to an embodiment includes a substrate, a plurality of light emitting device packages disposed on the substrate, a plurality of driving devices disposed on the substrate, and a connection terminal part disposed on the substrate, wherein an interval between both ends of the substrate and the connection terminal part is equal to or greater than an interval between the light emitting device package adjacent to the both ends of the substrate and the both ends of the substrate. The light source module is advantageous to slimming and thinning and has an advantage where a design of arrangement of a light emitting device package is free.

Light source module and lighting device

A lighting device may be provided that comprises: a cover; a member comprising a first placement portion, a second placement portion and a guide disposed between the first placement portion and the second placement portion; a light source module disposed on the first placement portion; a heat sink comprising a first receiver and a second receiver, the first receiver being defined by a flat surface and a plurality of heat radiating fins extending from an edge portion of the flat surface; and a circuitry disposed in the second receiver; wherein the second placement portion is disposed in the first receiver, wherein a first portion of the guide is couple to the cover and a second portion of the guide is couple to the heat radiating fins of the heat sink, and wherein the guide is spaced apart from the flat surface, the guide contacts the heat radiating fins, and the guide is disposed on the heat radiating fins.

Lighting device having separable light source and circuitry

A lighting device may be provided that includes: a housing having a top opening and a bottom opening; an optical plate disposed in the top opening; heat sink disposed in the bottom opening; a driving unit which is received in the housing, disposed between the optical plate and the heat sink and receives external electric power; and light source which is received in the housing, disposed between the optical plate and the driving unit, spatially separated from the driving unit and is electrically connected to the driving unit.

Lighting device

A lighting device including: a light emitting module; a heat sink which is disposed on the light emitting module; a heat sink fan which is disposed over the heat sink; an upper case which covers the heat sink fan and the heat sink; and a lower case which is coupled to the upper case and fixes the light emitting module. A first air inlet is disposed in the lower case. A second air inlet is disposed in the upper case.

A lighting device may be provided that comprises: a heat sink comprising a top surface and coupling structures which comprise a first coupling structure and a second coupling structure formed on a side surface of the heat sink; a light source disposed on the top surface of the heat sink; a lens unit disposed on the light source and comprising a first coupling portion which is coupled to the first coupling structure of the heat sink; and a cover unit comprising an optical member which is disposed on the lens unit, and a second coupling portion which is coupled to the second coupling structure of heat sink.

A lighting device may be provided that includes: a light source including: a member which includes a first placement portion and a second placement portion; a light source module which is disposed in the first placement portion; and a first terminal which is disposed in the second placement portion and is electrically connected to the light source module; and a heat sink including: a first receiver in which the second placement portion of the member is disposed; a second receiver in which a circuitry is disposed; and a second terminal which is disposed corresponding to the first terminal of the light source.
