Abstract: A planar light source apparatus includes a number of lighting elements disposed in a common plane, and a number of mirror reflectors arranged perpendicular to the common plane and facing the lighting elements. The mirror reflectors each have a reflecting surface facing the lighting elements. The light elements are arranged in a lattice such that the distance from one of the reflectors to the nearest lighting element is a maximum of the half the distance between two adjacent lighting elements.

Abstract: The present invention discloses a regular circuitry for reducing ripple resulting from a line voltage transmitting to a secondary side of a power transformer. The regular circuitry electrically connected in parallel with the power transformer includes a ripple sampling circuit, a proportional amplifier circuit, and a reversing amplifier circuit. The ripple sampling circuit selects a sampling ripple from the input port of the power transformer, which is electrically connected in series between a primary side rectification circuit and a secondary side rectification circuit. The proportional amplifier circuit receives the sampling ripple to generate an amplified sampling ripple. The amplified sampling ripple transmits to the reversing amplifier circuit so that a reversed sampling ripple is generated. Thus, the reversed sampling ripple can be input to the output port of the power transformer to superimpose on the signal output from the power transformer to reduce the ripple resulting from the line voltage.

The body has an inner wall formed with a receiving chamber for receiving the electronic ballast and the socket which is rested on the electronic ballast. The fixing seat has one end locked on a closed end of the body. Each of the two safety locking members is mounted and locked between the body and the fixing seat, so that the body and the fixing seat may be locked with each other, thereby integrally combining the body with the fixing seat. Thus, the separation device may be assembled and disassembled easily and conveniently, thereby facilitating replacement and maintenance of the separation device of the present invention.
