in prior art, in the termination of LED fluorescent tube, be built-in with power supply, power supply can produce amount of heat in use, therefore, needs in time the heat conduction of power generation to be distributed.Otherwise a large amount of heat accumulations, in inside, termination, causes power supply temperature to raise, easily cause power failure, power supply to reduce service life, produce the aging series of problems that equals of termination sheathing material.At present, the mode generally adopting is to pour into heat-conducting glue in the shell of termination.But the heat-sinking capability of aforesaid way is limited, and increase cost, reduce production efficiency.
Summary of the invention
for the problems referred to above, the purpose of this utility model is to provide a kind of LED fluorescent tube, and its termination has good heat-sinking capability.
for solving the problems of the technologies described above, the technical solution adopted in the utility model is:
a kind of LED fluorescent tube, comprise body, be plugged in substrate in body, be arranged at the termination on body one end along the length direction of body, on described substrate, be provided with the LED lamp pearl of multiple integration packagings, described termination comprise have cavity housing, fit in inner walls heat-conducting piece, be arranged at the power supply on heat-conducting piece, described LED lamp pearl is electrically connected mutually with power supply, described housing is made up of heat-conducting plastic, and described heat-conducting piece is made up of metal or metal alloy.
preferably, described power supply is IC power supply.
preferably, described power supply is Switching Power Supply.
preferably, described power supply is resistance-capacitance depressurization power supply.
preferably, on described heat-conducting piece, be provided with draw-in groove, described power supply removably inserts in draw-in groove.
preferably, the thermal conductivity factor of described heat-conducting plastic is more than or equal to 0.25W/mK.
preferably, described housing is made up of nano composite plastics.
preferably, described heat-conducting piece is made up of the one in aluminium, copper, aluminium alloy, copper alloy.
preferably, described housing is sheathed on the end of body.
the heat-conducting plastic that the utility model is addressed refers to and inorganic filler is dispersed in to the heat-conductive composite material forming in plastic substrate with sub-micron grade to nano-grade size, and the diameter of inorganic filler is wherein 10
