Latest Patents
One of Yang-Jui Chao's latest patents is for a lamp tube. This lamp tube includes a lamp shade, connectors fixed to opposite ends of the lamp shade, and a circuit board received in the lamp shade, which is electrically connected with the connectors. At least two resilient members protrude from opposite sides of the circuit board. Each resilient member is resiliently deformed and urged into contact with an inner surface of the lamp shade. The deformation of the at least two resilient members provides a spring push force to the circuit board, thus causing it to tightly engage the inner surface of the lamp shade, retaining the circuit board in position inside the lamp shade.
Another significant patent is for a driving circuit and illumination apparatus using the same. This illumination apparatus includes an LED and comprises a battery holder, an AC/DC adapter interface, an LED unit, and a switch unit. The battery holder is configured to receive a battery, while the AC/DC adapter interface connects to an AC/DC adapter. When the AC/DC adapter is not connected, the switch unit allows the driving unit to receive power from the battery. Conversely, when the AC/DC adapter is connected, the switch unit turns off to allow power from the AC/DC adapter.
