Refraction-type LED ceiling lamp

A refraction-type LED ceiling lamp, especially a plate-type ceiling lamp which is used on an indoor ceiling, includes primarily a fiber light guide plate, a reflection surface of which is provided with multiple chip-shape reflection elements, distributed in arrays. A chip size of the reflection elements decreases gradually toward an entrance surface by a geometric series; whereas, a gap between the reflection elements increases gradually. A reflection curve of the reflection element allows light to be projected out uniformly and a required illumination angle to be achieved.

Piezoelectric Pump

A piezoelectric pump having a first opening in a center portion of a pump body, and a second opening apart from the center. An outer peripheral portion of a metal diaphragm is fixed to the pump body, and a piezoelectric element having a size that covers the first opening and does not cover the second opening is bonded to a back center portion of the diaphragm. By applying a voltage near the resonance frequency to the piezoelectric element, a portion of the diaphragm opposing the first opening and a portion of the diaphragm opposing the second opening are bent in opposite directions so that fluid is drawn in from one of the first opening and the second opening and is discharged from the other opening. Such a piezoelectric pump can increase the discharging pressure, and can reliably discharge the fluid even under a condition where the pressure on the discharging side is high.
