An astral lamp is provided to adjust a color rendering, a brightness, and a color temperature by variably driving plural LED(Light Emitting Diode) chips independently from one another. An astral lamp includes a light source module(110), a reflector(150), and an elevator. Plural LEDs are arranged along a length direction of a bar-type core member to expose the LEDs from an outer periphery of the light source module. The light modules are arranged so that an exit axis of the LED is normal to the outer periphery of the light source. The light source module is coupled with the reflector through a central coupling member. Plural stripe-type sector reflective surfaces are formed in a step-wise cross-sectional shape on the reflector. The light received along the exit axis of the LED is reflected toward a front portion of the core member. The elevator elevates the light source module in a vertical direction with respect to the reflector. |
