Abstract

The utility model discloses a removable formula electronic ballast for fluorescent lamp, including the electronic ballast circuit board, in the box body of circuit board installation, be equipped with on the box body with input, output electrode that the circuit board electricity is connected still including holding the power supply seat of electronic ballast box body be equipped with on the power supply seat with input, output electrode corresponding input, output electrode on the box body. When the electronic ballast needs to be replaced, the clamping tenon can be taken out of the locking hole, and then the ballast box body is taken out of the power supply base, so that a user can replace the damaged electronic ballast at any time, and the convenience of maintenance is guaranteed.

Description

A kind of changeable type electric ballast

Technical field

The utility model relates to the electric ballast that is used on the fluorescent light fixture, is specifically related to a kind of electric ballast that is convenient for changing.

Background technology

In the prior art, the fluorescent light fixture of T8, T6, T5 model is energy-conservationly all to change the employing electronic ballast into by the original inductance type ballast that adopts, but electrochemical capacitor and trigger triode in the assembly of electronic ballast very easily damage, when changing, whole electric ballast need be pulled down replacing,, have certain specialty difficulty for the people who is not proficient in the electrician, dangerous, while replacement cost height.

The utility model content

The purpose of this utility model is, a kind of above-mentioned defective of prior art that overcomes is provided, and under the state of safer replacing, can use the changeable type electric ballast of using on light fixtures such as T8, T6, T5, straight pipe type or ring-like formula.

The technical scheme that the utility model provides is as follows: a kind of changeable type electric ballast that is used for the fluorescent light fixture, comprise the electronic ballast circuit board, in the box body that circuit board is installed, on box body, be provided with the input, the output electrode that are electrically connected with described circuit board, also comprise the power supply supply seat that can hold described electric ballast box body, be provided with on the described power supply supply seat with described box body on the corresponding input of input, output electrode, output electrode.

In above-mentioned changeable type electric ballast, input, output electrode on the described power supply supply seat are copper electrodes, and described output, input copper-base can be located at the same side or its both sides or its top of power supply supply seat housing.

In above-mentioned changeable type electric ballast, be provided with in the bottom of mounting circuit boards box body one be communicated with circuit board the LED luminous tube, can show whether the changeable type electric ballast damages.

In above-mentioned changeable type electric ballast, the contour structures of described electric ballast box body can be one of following array structure: trapezoidal flat cuboid, non-positive circular bluff body, inequilateral quadrangle bluff body.

In above-mentioned changeable type electric ballast, have microscler lockhole at the dual-side of described power supply supply seat, other is provided with one and can inserts and prevent the tenon that the electric ballast box body comes off in this lockhole.

The utlity model has following advantage: with the changeable type electric ballast according to preventing that wrong trapezoidal minor face from inserting power supply supply seat in last design, and with in two tenons insertion lockholes changeable type electric ballast box body being fixed in power supply supplies.When needs are changed, tenon can be taken out from lockhole, again the ballast box body is taken out from Power Block, can allow the user electric ballast that has damaged can be changed at any time, ensured the convenience of maintenance.

Embodiment

With reference to Fig. 1; Earlier finishing the electronic ballast circuit board that can work after tested with one inserts among the trapezoidal long strip type plastic box body 11, one end of plastic box body 11 has a protecgulum 12 that is provided with two power input terminals, its other end has a bonnet 13 that is provided with 4 current output terminal, output on the ballast circuit board or input interface are welded with above-mentioned terminal respectively, constitute the fluorescent lamp current supply circuit, again working of plastics 11 is shut, just manufacture and finish a changeable type electric ballast, be provided with a LED lamp 15 that is communicated with the ballast circuit board in the bottom surface of working of plastics 11, be available for users to know that this electric ballast 11 is work or does not work.

With reference to Fig. 2; It is identical with electric ballast box body 11 to make a shape with flame-retarded plastic again, and the power supply supply seat 21 that each external dimensions is big 2 millimeters, power supply supply seat 21 is being provided with 6 copper-

bases

22,23 at the position with input of the power supply of electric ballast box body 11 corresponding protecgulums 12 and bonnet 13 and electric current output, can make input power supply that electric ballast box body 11 is required and institute must output current can conduct electricity with external power source and fluorescent lamp formation by the copper-

base

22,23 at power supply supply seat 21 two ends fully and be connected.

With reference to Fig. 4, power supply supply seat 21 can adopt securing member to be connected with the fixedly connected mode of light fixture 31 or the mode of welding or embedding is fixed, no longer indicate explanation in the drawings, the shape of power supply supply seat 21 can cooperate the external form of electric ballast 11 to change into the flat cake body of non-positive circle, or the flat cake body of inequilateral quadrangle, as long as external dimensions guarantees the input of power supply and the output of electric current for big 2 millimeters, the body of looking lamp interior can no longer indicate or explanation among the figure arbitrarily for it.

With reference to Fig. 2, Fig. 3; Respectively have an elongated hole 24 at the two ends of power supply supply seat 21, other is provided with two can insert the tenon 14 that comes off of preventing in the elongated hole 24, power supply supply seat 21 can be installed in T8, T6, T5, in the various fluorescent light fixtures of straight pipe type or annular, again changeable type electric ballast box body 11 is inserted, re-use the tenon 14 that prevents to come off Figure 31 is finished in the two fixing i.e. configuration, the user can know that electric ballast is work or does not work according to LED 15, whether decision changes electric ballast 11, if electric ballast 11 has damaged, can extract out and prevent to come off tenon 14, from power supply supply seat, take out electric ballast 11, change a new product again, can finish the maintain and replace of self-convenience.
