A kind of LED power supply and there is the LED fluorescent lamp of this LED power supply
Technical field
The present invention relates to lighting technical field, particularly relate to a kind of LED power supply and there is the LED fluorescent lamp of this LED power supply.
Background technology
LED fluorescent lamp adopts light emitting diode as light source, and light efficiency is higher, more energy-conservation, longer service life, and more environmental protection.LED fluorescent lamp energy-saving is up to more than 70%, and it is more than 10 times that the life-span is common fluorescent tube, become the ideal product that the current stage replaces fluorescent tube.
In prior art, as shown in Figure 5, almost on market, all LED fluorescent lamps are all the LED fluorescent lamps 22 that adopts built-in power.So-called built-in power just refers to power supply is positioned over to fluorescent tube the inside.This built-in great advantage can be made the existing fluorescent tube of direct replacement exactly, and without original circuit is done to any change.
For example: the Chinese invention patent that application number is 201120020876.4, " a kind of LED lamp with starter " disclosed, its technical scheme comprises LED fluorescent tube and LED starter, every one end of LED fluorescent tube is all provided with two terminals, two terminal short circuits of LED fluorescent tube one end, two terminals of the other end are distinct terminals, one of them distinct terminals is for joining with an electric power incoming line, another distinct terminals is joined by a terminal of LED starter and short circuit, and another terminal and another electric power incoming line of short circuit join.LED fluorescent tube and LED starter are installed on the line-incoming lamp socket of two ends, the two ends line-incoming lamp socket that this LED lamp with starter can be compatible traditional, and above-mentioned LED lamp has adopted the mode of built-in power.
But there is following defect in this on-chip power formula LED fluorescent lamp: it is large that (1) changes power supply difficulty.Much larger than the service life of power supply, if power supply has been broken, directly change whole LED fluorescent lamp and will cause great waste the service life of LED, if only change power supply, must rely on again professional to carry out dismounting and change to circuit; (2) affect the luminous quality of LED.It is not evenly soft etc. that the heat sending makes LED fluorescent lamp in use can produce dazzle, shadow and bright dipping; (3) weak heat-dissipating.Because power acquisition is with built-in, the heat of power supply also just joins in fluorescent tube, makes the heat radiation of LED increase again difficulty, has shortened the service life of LED; (4) cost recovery is high, and built-in power formula has also increased the cost of the recycling of electronic waste, because power unit must be split out and processes respectively; (5) be difficult to reach the standard of safety.Due to on-chip power, to reaching safety standard, make a big impact.
Because the LED fluorescent lamp of built-in power exists above-mentioned defect, people have invented again a kind of LED fluorescent lamp of external power supply thereupon.
For example: the Chinese invention patent that application number is 200920134372.8 discloses " a kind of LED fluorescent lamp of external LED power supply ", its structure comprises LED daylight lamp body, on this LED daylight lamp body, be connected with an external LED power supply, described external LED power supply comprises PCB circuit board, input and output terminal, power pack, PCB circuit board is built in power pack, and input terminal is connected with LED daylight lamp body by PCB circuit board, lead-out terminal.Though the LED fluorescent lamp of the LED power supply that this is external has solved the more existing defects of the LED fluorescent lamp of built-in power, but because its power supply installation need to change original circuit, just can be fixed on the lamp plate of traditional fluorescent lamp, need to again change original lamp plate circuit structure.
