A mobile terminal includes an optical modulation projector. The mobile terminal also includes a control system, a projection control unit, and an optical modulation system. The control system outputs a projection control signal and image data. The projection control unit receives the image data from the control system, and generates and outputs a drive control signal depending on the image data received. The optical modulation system generates and modulates light and generates an image in response to the drive control signal and then scans the image for projecting onto a screen.

Disclosed herein is a method of controlling beam scanning timing and beam energy and a light beam scanning apparatus using the method. The light beam scanning apparatus includes a beam generation and processing means, a calculation and control means, a diffraction and scanning means and a scanning and processing means. The beam generation and processing means generates a beam and converts the beam into collimated light. The calculation and control means calculates scanning periods and beam energy, controls the operation periods and diffraction amounts of pixels of a light modulator. The diffraction and scanning means diffracts and modulates the beam and scans a plurality of diffracted beams.

Disclosed herein is a lighting apparatus. The lighting apparatus includes: a first light emitting unit including one or more main light sources radiating white light downward; one or more second light emitting units formed at the sides under the first light emitting unit and including one or more sub-light sources radiating color light that is mixed with the white light radiated from the first light emitting unit; and a light guide plate mixing the white light radiated from the main light sources and the color light radiated from the sub-light sources and radiating the mixed light downward.According to the embodiments, it is possible to remove non-uniformity of luminance of the lighting apparatus that can control color temperature by efficiently disposing main light sources radiating white light and sub-light sources radiating color light. Further, it is possible to increase efficiency of the lighting apparatus by radiating light, using all of the main light sources even at any color temperature.
