FLUORESCENT LAMP TYPE LIGHTING DEVICE USING HIGH BRIGHTNESS LED

摘要

A fluorescent lamp type lighting device is provided to exclude a ballast by using a high brightness LED(Light Emitting Diode) as an optical source. Both end parts of a lamp tube(110) are opened. One end of a pair of a heat sink(120) is combined inside both end parts of the lamp tube. The heat sink performs the heat discharge. A heat transfer member(130) of a circular shape or polygon is arranged inside the lamp tube. Both end parts of the heat transfer member are combined in a pair of heat sinks. A plurality of light emitting diodes(140) for the optical source are mounted in the outer surface of the heat transfer member. A pair of terminal cases(150) are combined in the outer side of the heat sink. The terminal case has a connection terminal(151). A PCB(Printed Circuit Board)(160) is electrically connected to an LED and a connection terminal. The PCB performs an operation control and a converter function of the LED.
