An embodiment of the present invention relates to a light unit. The light unit disclosed in the embodiment of the present invention comprises: multiple light-emitting devices having a light-emitting chip which has multiple light-emitting structures, and having a heat-radiating plate on which the light-emitting chip is arranged; a housing on which the multiple light-emitting devices are arranged; and a resin member which fills the housing and covers the multiple light-emitting devices. The light-emitting chip has a shape of which the length is longer that the width, and the light-emitting structures are separable in the lengthwise direction. The light-emitting chip comprises; a board for supporting the multiple light-emitting structures; and a projection unit having a ridge in each of the multiple light-emitting structures on the opposite side of the board. According to the present invention, manufacturing processes as well as heat-radiating efficiency can be enhanced. |
