    摘要: A lamp device includes a ring-shaped bulb, terminated at a prescribed annular length, each terminated portion of which is formed in a linear shape so as to make the bulb axis of one of the terminated portions coincide with that of the other terminated portion, and a base structure rotatably mounted around the opposite terminated portions of the bulb. Thus, the location of the bulb can be adjusted to a desirable position by the rotation of the bulb when the lamp device is attached to an external supporting device.
