With regard to existing daylight lamp fixture, must on lamp socket, install ballast, and fluorescent tube is installed on lamp socket and is electrically connected at ballast, external power source is converted to by ballast to the electric power of high frequency and high pressure, in order to activate fluorescent tube, and after fluorescent tube is lighted, continuing provides stabling current to fluorescent tube, makes fluorescent tube that illumination is provided.
Yet the service life of fluorescent lamp is not long, especially, in the frequency opening and closing place comparatively frequently, its loss is very fast.And because fluorescent tube receives ac signal, therefore when luminous, can produce flicker, cause the problem of user's eyes discomfort.
Since light emitting diode (Light Emitting Diode; LED) since development, due to itself luminous characteristic, be the illumination that is applied to directive property at the beginning, for example: the status indicator lamp of the machinery equipment in factory, or the use of the traffic lights such as traffic lights.But because LED has advantages of that efficiency is high, power consumption is low, the life-span is long, reliability is high, reaction speed is fast and failure rate is low, add the raising of environmental consciousness now, so LED lamp transfers room lighting to from traditional directive property illumination gradually, to replace existing daylight lamp fixture.
Although LED has above-mentioned various advantages, but because the popularity rate of existing fluorescent lamp is quite high, and LED lamp is neither identical in structural design and on circuit with fluorescent lamp, therefore, if replace existing fluorescent lamp with LED lamp, just whole group of daylight lamp fixture must be removed, and be replaced with LED light fixture, time-consuming taking a lot of work not only, cost is also high.If so LED lamp is directly installed on to existing daylight lamp holder, can causes LED lamp to burn from the different of project organization because of circuit.
Therefore, the LED lamp that how to overcome above-mentioned prior art cannot directly be installed on the problem of existing daylight lamp holder, has become in fact the problem of desiring most ardently at present solution.
Summary of the invention
In view of the defect of above-mentioned prior art, the present invention discloses a kind of LED fluorescent tube, cannot directly be installed on the problem of existing daylight lamp holder to solve LED fluorescent tube.
LED fluorescent tube provided by the present invention is applied to have the lamp socket of ballast, and this LED fluorescent tube comprises light emitting module, the first controller and second controller.This light emitting module has first end and the second relative end, this first controller is arranged on the first end of this light emitting module, this second controller is arranged on the second end of this light emitting module, so that this light emitting module is electrically connected this ballast by this first controller or second controller.Wherein, this first controller or this second controller come from the electric power signal parameter of this ballast in order to adjust, and are sent to this light emitting module, luminous so that this light emitting module receives electric power signal after adjusting.
The present invention separately provides a kind of LED fluorescent tube, is applied to solar DC power system, and this LED fluorescent tube comprises light emitting module, has the illuminator being comprised of a plurality of light emitting diodes, and this light emitting module has first end and the second relative end.
As from the foregoing, LED fluorescent tube provided by the present invention, owing to thering is the first controller and second controller in fluorescent tube, therefore capable of regulating comes from the electric power signal of this ballast, to convert the receivable electric energy of lighting module in LED fluorescent tube to, make this lighting module receive electric power signal after adjusting and luminous, therefore also make the present invention can be without existing daylight lamp holder is removed, or change under the prerequisite of its structure, directly LED fluorescent tube is installed on to existing daylight lamp holder, not only simple and convenient in replacing operation, also can save meaningless expenditure.And, the invention is not restricted to ballast kind all applicable, electronic type or inductance type all can.
