Abstract
The utility model provides an LED tube, and aims to solve problems that the power supply structure of a conventional LED lamp is complex in circuit, high in cost, large in power supply size and low in power source factor. The LED tube comprises a high voltage integration IC, an aluminium substrate, and n sets of LEDs. Both the high voltage integration IC and the n sets of LEDs are connected on the aluminium substrate. All the LEDs are connected in a mixed connection mode of both parallel and series connection. A power supply drive and a luminescent plate are integrated, so that a complex drive circuit is simplified. A rectification circuit and a constant current source are merged, and an AC circuit is rectified directly via a bridge pile. The LEDs are connected in a mixed connection mode of both parallel and series connection, thereby preventing the whole set of LEDs or the whole tube from extinguishing once one tube stops working. Moreover, the cost and the failure rate are reduced, the size is minimized, and the power factors are improved.
Description
Technical field
The utility model relates to a kind of LED fluorescent tube, belongs to LED lamp technical field.
Background technology
Existing LED lamp is the operating on low voltage device of a necessary constant pressure and flow.Traditional LED always drive with the AC/DC conversion again the constant pressure and constant diffluence to drive the low-voltage LED diode promptly be outside the LED luminous plaque, to connect drive circuit again; This scheme makes driver be suitable for voltage wide (80V-260V), constant current accuracy is high; But its shortcoming is: 1, power supply architecture complicated circuit, cost height; Failure rate is also high; The damage of fluorescent tube 70% is a power failure almost, and power supply has become the restriction bottleneck of LED fluorescent tube fault, and the electrochemical capacitor power drive pipe transformer in the power supply etc. have restricted the quality bottleneck of power supply.2, power volume is big, and the two ends that are contained in the LED fluorescent tube make the length of illumination of whole fluorescent tube shorten 7%, have influenced the sight and the service quality of outward appearance.3, the power factor is low, is merely 40%～70%.
Summary of the invention
The purpose of the utility model is high for solving existing LED lamp power supply architecture complicated circuit, cost, and failure rate is also high, and power volume is big, the problem that the power factor is low, and then a kind of LED fluorescent tube is provided.
The purpose of the utility model realizes through following technical scheme:
A kind of LED fluorescent tube; Comprise the integrated IC of high pressure, aluminium base and n group LED lamp pearl; The integrated IC of said high pressure and n group LED lamp pearl all is connected on the aluminium base, and the series-parallel connection that adds series connection for parallel connection between every group of LED lamp pearl connects, every single ledly all encapsulate with twin-core; To save encapsulation overhead, improve single led brightness.
The beneficial effect of the utility model: the utility model power drives and luminous plaque are integrated, have simplified complicated drive circuit.Rectification circuit and constant-current source merge, and alternating current circuit is directly through the rectification of bridge heap.Adopt the parallelly connected series-parallel connection mode that adds series connection between several groups of LED lamp pearls, prevented a situation generation that the dead lamp of lamp causes whole group lamp pearl or whole piece fluorescent tube not to work.Reduce cost and failure rate, reduced volume, improved the power factor.
Description of drawings
The electrical block diagram of a kind of LED fluorescent tube that Fig. 1 provides for the embodiment of the utility model.
Embodiment
This embodiment provides a kind of LED fluorescent tube, and is as shown in Figure 1, comprises the integrated IC of high pressure, aluminium base and n group LED lamp pearl, and integrated IC of said high pressure and n group LED lamp pearl all are connected on the aluminium base, connect for the parallelly connected series-parallel connection that adds series connection between every group of LED lamp pearl.
Concrete, as shown in Figure 1, the drive circuit of LED and LED lamp pearl are incorporate, and parallel connection adds the series-parallel connection connection of series connection between several groups of LED lamp pearls, i.e. one group of LED lamp pearl such as L
1, L
2----Ln is for being connected in series another group LED lamp pearl such as Ln+
1, Ln+
2----L
2N is also for being connected in series, but also is connected in parallel simultaneously between every group of LED lamp pearl, like one group LED lamp pearl L
1With other several groups LED lamp pearl Ln+
1, L
2N+
1, L
3N+
1, L
4N+
1And L
5N+
1Between be connected in parallel, by that analogy.To have high-voltage rectifying and the integrated IC of high pressure of electric current constant current is connected on the aluminium base; The AC alternating current is through the constant electric current of the integrated IC output of high pressure; Electric current is all assigned on the n group LED lamp pearl again; Under the situation that the necrosis of any lamp pearl maybe can't be switched on one group of lamp pearl, electric current can all be assigned to this all the other lamp pearls of group lamp string, and all the other lamp pearls that make the LED fluorescent tube are not because of the lamp pearl of a non-conductive or downright bad and whole group of lamp pearl or whole fluorescent tube no power all.
The above; Be merely the preferable embodiment of the utility model; But the protection range of the utility model is not limited thereto; Any technical staff who is familiar with the present technique field is in the technical scope that the utility model discloses, and the variation that can expect easily or replacement all should be encompassed within the protection range of the utility model.Therefore, the protection range of the utility model should be as the criterion with the protection range of claims.
