Abstract: A tent is safely unfolded or folded when used and requires less time to unfold or fold and can be pitched automatically as well as manually to solve the problems of the prior art. In the tent, a worm gear and worm wheels are combined and tent connecting rods are attached to the worm wheels, respectively, so that when the worm wheels are moved, the tent connecting rods are moved to fold or unfold the tent. The worm wheel can be manually moved within the tent or the worm wheel can be automatically operated by providing a motor controlled through a remove controller so that the tent connecting rods can be unfolded or folded. In the tent, a central cavity part of a worm wheel body may be used as an air vent, and used as a passage for a smoke outlet from a heater in the winter.

Abstract: An optical semiconductor lighting apparatus having at least one or more clamping units are formed along a longitudinal direction of a race way. A first sealing unit finishes both ends of a housing attached to or detached from the clamping unit. A second sealing unit surrounds upper and lower portions of both edges of an optical member disposed on the bottom surface of the housing. A wireless communication unit receives a dimming signal through a wireless communication network, and outputs the received dimming signal to a power supply unit. The power supply unit supplies a DC voltage to the light emitting module to control the illuminance of the light emitting module according to the dimming signal input from the wireless communication unit.
