    摘要: An apparatus for manufacturing a surface light source apparatus in which a light guide pattern portion is formed on a light guide panel includes a pattern design system to which data about a pattern to be formed on the light guide pattern is input. A control system is connected to the pattern design system and transmits a position signal matching a coordinate value of each pattern to be formed on the light guide panel. A header moving portion mechanically moves vertically and horizontally according to the position signal received from the control system. A laser system outputs a laser beam according to a pulse signal synchronized with a movement of the header moving portion. A lens portion allows a laser beam output from the laser system to pass the header moving portion and to be focused on a scanning surface of the light guide panel. A warp prevention unit prevents the light guide panel from warping due to a local heating by the laser beam. An absorption and scattering prevention unit prevents smoke generated when the light guide pattern portion is formed on the light guide panel.

    摘要: A power supply apparatus for LED is provided. The power supply apparatus for LED includes a detector, a voltage dropper, and a control switch. The detector detects whether an LED is connected to the power supply apparatus. The voltage dropper drops a voltage applied to the LED. The control switch is connected to the voltage dropper in parallel, and changes a path of a power applied to the LED according to the detected result of the detector. Accordingly, the power supply apparatus for LED compensates for a low impedance of an LED to an impedance equal to or higher than a predetermined impedance at a time when connection of the LED is detected, thereby inhibiting an overcurrent from flowing in the LED.
