Description
Technical field
It is the fluorescent tube of light source with LED that the utility model relates to a kind of;
Technical background
The scheme that existing LED fluorescent tube adopts usually is that the LED driving constant-current power is built in fluorescent tube aluminium section bar radiator inside, causes the operating temperature of power supply higher, can influence the service life of power supply; And can be several times as much as service life of power supply under the normal condition service life of LED illuminator, when on-chip power, in case power supply breaks down, maintain and replace is inconvenience very.
Summary of the invention
In order to overcome the deficiency of prior art, the utility model provides a kind of the LED driving power has been placed independently in the power pack, is one with power pack and fluorescent tube through socket connection; Can dismantle easily between power pack and the fluorescent tube, isolate, can effectively reduce the operating temperature of power supply because of the radiator of external power supply and fluorescent tube; Improve the service life of power supply; When external power supply breaks down, can change power supply easily in addition, make fluorescent tube can continue to use, thereby improve the bulk life time of fluorescent tube.
The technical scheme that its technical problem that solves the utility model adopts is:
A kind of LED fluorescent tube of external power supply is made up of fluorescent tube 2 and 4 of a power pack, and fluorescent tube 2 has two kinds of different connected modes with power pack 4:
Said fluorescent tube 2 is by aluminium section bar radiator, diffuser, first lamp holder 1 at LED luminous plaque and two ends, 3 compositions of second lamp holder; Described power pack 4 is built-in with the LED constant-current supply; One end of power pack 4 has two electrode jacks 8; The output of LED constant-current supply is connected with two electrode jacks 8 respectively; Power pack 4 other ends are equipped with the 3rd lamp holder 5, have a locating hole 7 at the end face of the 3rd lamp holder 5, and the output of LED constant-current supply is connected with two contact pins of the 3rd lamp holder 5 respectively; Second lamp holder 3 and the power pack 4 of fluorescent tube 2 has an end of electrode jack 8 to become a complete fluorescent tube through socket connection; Power pack 4 is provided with circular alignment pin 9, two semicircle draw-in grooves 10 and outside fix covers 11 at the LED power output end; Alignment pin 9 is used for cooperating when preventing to assemble LED polarity opposite with locating hole 7, the location when draw-in groove 10 and positioning sleeve 11 are used for the grafting with fluorescent tube 2;
Perhaps; Fluorescent tube 2 is made up of aluminium section bar radiator, diffuser, LED luminous plaque and 1 in first lamp holder; There is an end of electrode jack 8 to be provided with two semicircular draw-in grooves 10 and positioning sleeve 11 at power pack 4; Directly the output with power pack 4 is plugged on fluorescent tube body 2, and the input of LED luminous plaque directly is connected with two electrode jacks 8 of power pack 4 outputs through lead.
Preferably, the 3rd lamp holder 5 on two lamp holders of fluorescent tube 2, first lamp holder 1, second lamp holder 3 and the power pack 4 is the G13 lamp holder.
The beneficial effect of the utility model is:
Constant-current driving power supply places independently in the power pack, effectively reduces the operating temperature of power supply, when power supply breaks down, can change power supply easily, significantly improves the bulk life time of power supply and fluorescent tube.
Description of drawings
Below in conjunction with accompanying drawing and embodiment the utility model is done further explanation.
Fig. 1: the utility model sketch map;
Fig. 2: power pack shell section figure;
Fig. 3: power pack and the fluorescent tube sketch map of directly pegging graft;
The specific embodiment:
Below in conjunction with the accompanying drawing and the specific embodiment the utility model is explained further details:
With reference to Fig. 1; The utility model discloses a kind of LED fluorescent tube; Comprise LED fluorescent tube 2 and independently external power supply box 4 two parts form; Fluorescent tube 2 is made up of aluminium section bar radiator, diffuser, LED luminous plaque and first lamp holder 1,3 in second lamp holder, and the input of LED luminous plaque is connected with two contact pins of second lamp holder 3, and the termination of second lamp holder 3 has an aperture that is used to locate 7; Power pack 4 is built-in with the LED driving power; End at power pack 4 has two electrode jacks 8; The output of LED driving power is connected with two electrode jacks 8 respectively, and power pack 4 is provided with circular alignment pin 9, two semicircle draw-in grooves 10 and outside fix covers 11 at the LED power output end, at the other end of power pack the end cap of the 3rd lamp holder 5 as power pack 4 is housed; The 3rd lamp holder 5 usefulness screws and power pack 4 are fixed together; The input of driving power is connected with two contact pins of the 3rd lamp holder 5 respectively, and fluorescent tube 2 is plugged on power pack 4 just becomes a complete fluorescent tube, during grafting second lamp holder 3 is inserted in the positioning sleeve 11; Alignment pin 9 inserts in the locating hole 7, can not occur opposite polarity situation when guaranteeing to peg graft and take place.
Present embodiment also has a preferred version to be: as shown in Figure 3; There is an end of electrode jack 8 to be provided with two semicircular draw-in grooves 10 and positioning sleeve 11 at power pack 4; Therefore need not second lamp holder 3 can directly be plugged on power pack with fluorescent tube body 2; The input of LED luminous plaque directly is connected with two electrode jacks 8 of power pack 4 outputs through lead, becomes that a power pack can not plug but fluorescent tube that driving power separates with radiator, when driving power breaks down; Need not the whole power pack 4 of changing, only need opened the 3rd lamp holder 5 of end cap built-in driving power replacing is got final product.
During concrete the realization, the 3rd lamp holder 5 on two lamp holders of fluorescent tube 2, first lamp holder 1, second lamp holder 3 and the power pack 4 is the G13 lamp holder.
