Abstract: A lighting device in which a heat sink and a cover are formed by co-extrusion and a manufacturing method for the same are provided. The heat sink and the cover may be co-extruded. A shape control portion may be formed at the heat sink to control a shape of a seating portion to seat a circuit substrate during extrusion of the heat sink. In addition, a light characteristic control portion may be provided between a light emitting diode (LED) and the cover to control characteristic of light generated from the LED.

Abstract: A light source module including a substrate, a plurality of light emitting devices installed on the substrate, and a plurality of lenses installed on the substrate to cover the plurality of light emitting devices, respectively, and each of the plurality of lenses having a pair of open end portions facing one another, the plurality of lenses arranged such that an open end portion of one lens faces an opened end portion of an adjacent lens is provided.

Abstract: The present invention relates to a spread lens and a light emitting device assembly using the spread lens for miniaturization and improving a spread characteristic of a lens. In accordance with the present invention, a spread lens spreading light emitted from a light emitting device may include a first lens surface through which the emitted light from the light emitting device is inputted; a second lens surface spreading the light inputted through the first lens surface to an outside; refraction parts which extend between both side ends of each of the first and second lens surfaces, are formed in a concave-convex shape, and refract the emitted light from the light emitting device; and support parts which extend at both side ends of the second lens surface and separate the refraction parts and the light emitting device from each other.
