Abstract
A non-polar LED light fixture power supply module has an input terminal and an output terminal respectively connected with the output terminal of the LED driver and the input terminal of the LED light fixture. The module is characterized in being a bridge type transfer circuit. The module of the utility model can remove the troubles of distinguishing polarities for user when mounting and replacing LED lamp, changes the LED light fixture form a polar light fixture into a non-polar LED light fixture; enables that the LED light fixture can work normally whether connected on the positive or the negative terminal of the output DC power source of the driver; and provides great convenience to user when installing or replacing LED light fixture.
Description
Technical field
The utility model relates to the LED light fixture, especially about a kind of Power Entry Module, makes the LED light fixture can receive the positive and negative terminal in led driver output DC source arbitrarily, can both normal power-up work.
Technical background
No matter the LED light fixture is Lamp cup shape or straight tube shape, all must join a driver.Driver can be the DC/DC type, also can be the AC/DC type, but no matter be the former or the latter, driver all is a direct current with being connected of LED, and direct current divides anodal, negative pole, as connects anti-LED lamp and just do not work, this just sit to lamp or support on installation LED light fixture bring very big inconvenience; Adorn instead, even to take for the LED lamp be bad.Need a kind of both positive and negative polarity that is regardless of, install and change nonpolarity very easily LED light fixture.
Summary of the invention
At above deficiency, the purpose of this utility model is to provide a kind of LED lamp power input module, makes the LED light fixture can connect DC power supply arbitrarily, and needn't distinguish both positive and negative polarity, thereby make the LED light fixture become nonpolarity light fixture from the polarity light fixture is arranged.
The technical solution of the utility model realizes in the following manner: a kind of nonpolarity LED lamp power module, power module has input and output, be connected with LED light fixture input with the led driver output respectively, it is characterized in that: power module is a bridge conversion circuit.
Described power module is the monolithic type, has 4 terminal pins, and two terminal pins of identical one side are just connecting the LED light fixture, the negative supply input, and two lead-in wires of another side are connected with the led driver output, form nonpolarity light fixture.
Described power module is two piece types, and A is arranged, two of B, and every has three lead-foot-lines, and two terminal pins of identical one side are just connecting the LED light fixture, the negative supply input, the other end single line terminal pin of A piece and B piece is connected with the led driver output respectively.
The utility model, the user is installing, when changing the LED lamp, need not to distinguish the hardship of polarity.Thereby make the LED light fixture become nonpolarity light fixture from the polarity light fixture is arranged.This module makes the LED light fixture can receive the positive and negative terminal in led driver output DC source arbitrarily, can both normal power-up work, change the outfit to the user, and change the LED light fixture and bring great convenience.
Description of drawings
Fig. 1 is the utility model structural representation.
Fig. 2 is that power module is the connection diagram of monolithic type.
Fig. 3 is that power module is the connection diagram of two piece types.
Embodiment
Known that by Fig. 1 structure of the present utility model is made up of power module, driver and LED lamp, the terminals of power module are connected with driver, output and LED light fixture just, the negative supply input forms nonpolarity light fixture.Thereby when making user installation change the LED light fixture, need not distinguish, identification both positive and negative polarity and can inserting arbitrarily gets final product.
As shown in Figure 2, be that power module is the connection diagram of monolithic type.Power module is the monolithic type, is applicable to the single end LED lamp.3 just are being connected the LED light fixture, the negative supply input with 4 as long as will go between; Lead-in wire 1 and 2 promptly can be changed into nonpolarity power input.
As shown in Figure 3, power module is the connection diagram of two piece types.Power module is two pieces, is applicable to both-end LED lamp., A piece 2 links to each other with B piece 2 and inserts LED lamp positive pole, and A piece 3 links to each other with B piece 3 and inserts LED lamp negative pole, and then A piece 1 and B piece 1 promptly can be changed into nonpolarity power input.
