摘要： An ink-jet image forming apparatus. The ink-jet image forming apparatus includes a print head having a plurality of nozzles to eject ink, an ink tank to store the ink, an ink supply passage to supply the ink in the ink tank to the print head, an ink return passage to return the ink in the print head to the ink tank, a regulator mounted in the ink supply passage to regulate ink flow supplied to the print head, a shut-off valve mounted in the ink supply passage, between the ink tank and the regulator, to intercept ink flow supplied to the regulator, and an ink pump mounted in the ink return passage to forcedly flow the ink in the ink return passage. The ink pump is configured to be driven in forward and reverse directions so as to change an ink flow direction. Since the shut-off valve intercepts forcedly the ink flow in the ink supply passage, the ink in the ink tank is prevented from flowing abnormally to the print head and leaking from the print head.

摘要： An image forming apparatus is configured to include an ink supply device with an ink flow path to a print head to eject ink toward a printing medium and a flow regulating valve for the ink flow path. The flow regulating valve to perform opening/closing operations according to at least the ejection amount of ink from a print head. The ink supply device includes a body, which has an ink discharge path coupled to the print head, a first chamber coupled to the ink discharge path, an ink introduction path coupled to the ink tank, a second chamber coupled to the ink introduction path, and a connecting path to coupled the first and second chambers to each other. The flow regulating valve is configured to open or close the connecting path, and a valve drive unit is configured to operate the flow regulating valve.

摘要： A light emitting diode floodlight includes a hollow housing, a lens, a cover, a light source, an illumination reflector, an intermediate portion, and a power source. The cover is coupled to the end of the housing and configured to hold and support the lens. The light source has a pyramidal frustum-shaped portion installed at an opposite end of the housing. The illumination reflector is installed within the housing so as to surround a periphery of the pyramidal frustum-shaped portion of the light source. The intermediate portion is connected to a first heat sink of the light source and has a second heat sink on an outer peripheral surface thereof. The power source has a power supply electrically connected to the light source.
