Described radiating block is provided with the link slot with light pipe, and light pipe and link slot are pegged graft.

Its cross section of described light pipe is annular, and the radiating block that is connected with circular ring section is provided with the insertion pipe with light pipe, and light pipe and insertion pipe (8) are pegged graft.

Be provided with LED driver in the pipe of described light pipe, external power supply is electrically connected to the LED lamp plate by LED driver.

The radiating block (1 ') that connects on two faces of described longitudinal section can be connected as a single entity.

The beneficial effects of the utility model: due to luminous be by being luminous by the reflective spot scattering of whole fluorescent tube, not only light-emitting area is large, light is even, and lamp tube wall is owing to being arc, save the space than the flat lamp with homalographic significantly, and can be to the side-irradiation of fluorescent tube, whole irradiation ambient light is even; Owing to being whole lamp luminescence, be accustomed to the use of the general user of traditional fluorescent tube and more easily adapted to for making, due to more energy-conservation than traditional fluorescent lamp, effect of light is better, more universal the use; Owing to just in cross section and the middle section of fluorescent tube, single LED lamp pearl being set, obviously reduce than traditional LED fluorescent tube with the quantity of lamp pearl, so the cost of manufacture decrease.
