The specific embodiment
Below in conjunction with Figure of description the utility model is described further:
The AC LED fluorescent tube, comprise lampshade 2, the lamp holder 1 at two ends and pin 4, lampshade 2 adopts the transparent pipe of PC, be provided with integrated encapsulated LED luminescence component 3 in the described lampshade 2, integrated encapsulated LED luminescence component 3 is made up of circuit board 7 with an electronic circuit and integrated brilliant LED6 of heap of stone, circuit board 7 adopts the two-sided copper coin of CEM-3, circuit board 7 is provided with the electric current that the EMC/EMI circuit is controlled integrated brilliant LED6 of heap of stone, integrated brilliant LED6 of heap of stone is set to a group or more and is welded on the circuit board 7, every group of integrated brilliant LED6 series connection of heap of stone back is arranged in parallel with other groups, circuit board 7 and pin 4 are connected by lead, described integrated encapsulated LED luminescence component 3 surface-coated are provided with layer of even silica gel 5, and structure described in the utility model is applicable to T5, T6, the fluorescent tube of multiple model such as T8.
The utility model adopts integrated brilliant LED6 of heap of stone to connect and encapsulation in parallel, improve luminous efficiency, use EMC/EMI circuit control LED electric current, single crosstalk stream is 35mA, makes led circuit keep constant temperature, adopt the two-sided copper coin of CEM-3, as the basis of conducting heat, the LED lamp is worked under 35-40 degree constant temperature, can light decay, fluorescent tube adopts the PC Transparent lamp tube, impact resistance is difficult for breaking, control LED work constant temperature, thereby need not do heat radiation, do not use the aluminium flake heat radiation, alleviated the weight of LED fluorescent tube, also reduced the fluorescent tube cost, can replace traditional tube completely and directly replace, need not the professional person.
Adopt the EMC/EMI integrated circuit, directly take AC power, power supply is incorporated in fluorescent tube inside, do not take up space, adopt integrated encapsulation technology, improved optical efficiency, the LED integrated light-emitting, become a line source, do not put luminous effect, light efficiency is good, has the AC frequency multiplication, fluorescent tube does not glimmer fully, can control the LED heating, does not need to use aluminium base, need not to use the heat radiation aluminium flake, directly adopt alternating current, can be directed in fluorescent tube inside, energy-saving effect is obvious, can reach energy-conservation more than 60%, circuit board adopts general CEM-3 dual platen, and application circuit board copper-clad surface freely reaches the distribution heat radiation, effectively reduces product cost.
