Description

T5 fluorescent tube built-in power

Technical field

The utility model relates to a kind of T5 fluorescent tube, further relates to the T5 fluorescent tube that a kind of inside can be placed with power supply.

Background technology

The T5 fluorescent tube is a kind of of fluorescent lamp (or claiming fluorescent lamp, light pipe, fluorescent tube), and diameter is 5/8 inch, and about 16 millimeters of T5 fluorescent tube belongs to a kind of of gaseous discharge lamp.Its electrification activates mercury vapor in argon or neon, form plasma and send short wave ultraviolet, makes phosphorus matter send visible fluorescence with illumination.General fluorescent tube is equipped with socket and reaches the fixedly position of fluorescent tube to connect power supply with the glass manufacturing at two ends.

The external diameter of T5 fluorescent tube has only 15.3mm, and internal diameter is 9mm, and general transformer can't be put into.Because the T5 caliber is much thinner than T8, T12 fluorescent tube footpath, the intert-gas atoms that fluorescent tube is filled and the elastic collision probability of electron production are higher, and energy loss is littler, and this raising to light efficiency also is very favorable.Because the inert gas that filled is the unique inert mixed gas of three aurora illumination allotment, negative electrode that can not only the better protection fluorescent tube with help the take-off of fluorescent tube, and can suitably reduce the fluorescent tube the blowing pressure.Further improve the luminous flux output of fluorescent tube.Therefore, though the power of fluorescent tube is low, total light flux does not reduce, and the light efficiency of fluorescent tube is improved.

In order to practice thrift cost; T5, T4 have adopted the form of miniature support to sell, and are exactly the inside, miniature space that ballast is contained in support, the efficient of this ballast and fair all not very good; Cause should very high efficiency fluorescent tube brightly not as conventional T8 fluorescent tube on the contrary, the life-span aspect also a bit gives a discount.

Therefore, existing T5 fluorescent tube subject matter is that power supply can't be put in inside, has influenced luminous efficiency.

Summary of the invention

In view of above content, be necessary to provide a kind of and can save cost, the T5 fluorescent tube of built-in power.The utility model provides a kind of built-in power of T5 fluorescent tube; Comprise magnet ring, output rectifier and filter and input rectification circuit; Its middle magnetic ring, output rectifier and filter are positioned over one side, place of T5 spot plate, and output rectification circuit is positioned over the another side of lamp plate, and magnet ring replaces transformer of the prior art; Be used to regulate the voltage of said fluorescent tube, said output rectifier and filter comprises patch capacitor, the SMA high frequency paster of two 50V106.

Because the power panel width is: 8.8mm, the height of power supply has only 3mm, and the magnet ring size is 10mm*6mm*5mm, places it in above the point space on the power supply edges of boards, adopts patch capacitor and SMA high frequency paster can reduce the space as far as possible; In addition, the electric wire that the electrolysis of input rectification circuit and transformer are placed on after the two end rectifications passes from the centre, is positioned over the another side of power panel.

Through magnet ring is replaced transformer, with changing less patch capacitor of volume and SMA high-frequency diode paster in the output rectifying and wave-filtering electric current, effectively reduced power volume, make power supply can put into fluorescent tube inside, improved giving out light effect and useful life of fluorescent tube.

Description of drawings

Combine embodiment that the utility model is done further to describe with reference to the accompanying drawings.

Fig. 1 is the schematic diagram of the utility model T5 tube circuit.

Fig. 2 is that the internal structure of this practical T5 fluorescent tube is schematically graphic.

Embodiment

See also Fig. 1 and Fig. 2; The built-in power of the T5 fluorescent tube of the utility model dress preferred embodiment comprises magnet ring T 1, output rectifier and filter and input rectification circuit; Its middle magnetic ring T1, output rectifier and filter are positioned over one side, place of T5 spot plate; Output rectification circuit is positioned over the another side of lamp plate, and magnet ring replaces transformer of the prior art, and said output rectifier and filter comprises patch capacitor C6, C7, the SMA high-frequency diode paster of two 50V106.

Among Fig. 2, Fig. 2 A representes the monnolithic case of fluorescent tube, and Fig. 2 B representes original 3W transformer that uses, and Fig. 2 C representes original 6W transformer that uses, and Fig. 2 D representes magnet ring, and Fig. 2 E representes rectifying part.

Preferably, the power panel width is: 8.8mm, and the height of power supply has only 3mm, and the magnet ring size is 10mm*6mm*5mm, places it in above the point space on the power supply edges of boards, adopts patch capacitor and SMA high frequency paster can reduce the space as far as possible; In addition, the electric wire that the electrolysis of rectifying part and transformer are placed on after the two end rectifications passes from the centre, is positioned over the another side of power panel.

The utility model is primarily aimed at the improvement that power supply is carried out in the T5 fluorescent tube; The above is merely the utility model preferred embodiment; Non-so promptly limit to the claim of the utility model; So the simple and easy variation and the equivalent transformation of doing with the utility model specification and graphic content such as all should be contained in the claim of the utility model.
