Linear lighting device

A linear lighting device comprising:

• an installation rail including a housing and a power supply terminal, the housing being fixed to an installation object surface and having an accommodating space formed therein, the accommodating space having an open side in one surface thereof, the power supply terminal being disposed in the accommodating space of the housing in a length direction thereof;
• at least one linear lighting module including a power connection terminal and a light emitting device, the power connection terminal being electrically connected to the power supply terminal, the light emitting device being electrically connected to the power connection terminal, the linear lighting module being detachably coupled to the accommodating space of the housing;
• and
• a light transmissive cover detachably coupled to the housing so as to close the open side of the accommodating space of the housing;
• wherein the installation rail has a first coupling portion formed thereon and the lighting module has a second coupling portion formed in a position corresponding to the first coupling portion, the first coupling portion and the second coupling portion being engaged with each other in a state in which the lighting module is accommodated in the accommodating space of the housing,
• wherein the first coupling portion and the second coupling portion have protrusions formed on surfaces thereof facing each other, the protrusions being engaged with each other, and wherein both ends of the protrusion of the second coupling portion is provided with inclined surfaces to guide separation of the second coupling portion,
• wherein the installation rail further includes a side member detachably coupled to a side portion of the housing;
• wherein the side member has a catching portion which is bent from a bottom portion thereof and which is adhered to an outer circumferential portion of the installation object surface around an installation groove.
