FLUORESCENT LAMP TYPE LED LIGHTING TUBE, AND FLUORESCENT LAMP TYPE LED LIGHTING DEVICE EQUIPPED WITH THIS LIGHTING TUBE

摘要

PROBLEM TO BE SOLVED: To provide an LED lighting tube equipped with a heat sink coated with a heat-radiation accelerating film which is reduced in noise and has a long life, and can accord to a starter formula for an existing fluorescent lamp other than an inverter formula, and can diffuse and radiate heat generated from an LED element light source outside the system, and an LED lighting device using the above lighting tube.

SOLUTION: The fluorescent lamp type LED lighting tube 50 equipped with a heat sink 8 at an upper part capable of being mounted as it is on a socket 62 of an existing fluorescent lamp lighting tube 60 with a starter formula of either a glow one-lamp, or a rapid one-lamp and a rapid two-lamp formula. An LED control circuit 20 with an output voltage of a ballast 63 of the existing fluorescent lamp 60 as a threshold value has relays 21 to 24 incorporated in the fluorescent lamp 60 automatically changed over according to the starter formulae. Moreover, the heat-radiation accelerating film 103 is coated on the heat sink 8 to radiate heat generated from the light source at high efficiency to the outside.
