Abstract
The utility model belongs to serially-connected LED bulbs without a transformer driving circuit. The serially-connected LED bulbs comprises a plug (J1), a bulb 1 (AC/LED1), and a bulb 2 (AC/LED2) and are characterized in that one end of the bulb 1 (AC/LED1) is connected with one ends of variable resistors (PTC1) and (PTC2) and one ends of resistors (R4) and (R5). The other ends of the variable resistors (PTC1) and (PTC2) and the other ends of the resistors (R4) and (R5) are connected with the second end of the plug (J1). The other end of the bulb 1 (AC/LED1) is connected with the one end of the bulb 2 (AC/LED2). The other end of the bulb 2 (AC/LED2) is connected with one ends of resistors (R3), (R2), (R7), and (R6). The other ends of the resistors (R3), (R2), (R7), and (R6) are connected with the first end of the plug J1. The serially-connected LED bulbs prevents a transformer and has characteristics of low environmental factor influence, high reliability, no transformer luminous efficacy loss, no pollution, no reduced efficiency caused by heat, saving material, low cost, good energy saving effect, and long service life.
Description
Technical field
The utility model belongs to illuminating lamp, particularly a kind of transformer drive circuit series LED lamp.
Background technology
The LED lamp is that a kind of power savings is remarkable, is the extraordinary Novel lighting lamp of a kind of application background.But price comparison is high, and main cause is the AC/DC transformer drive circuit; Be subject to the drive circuit life-span, and drive circuit is easily leading because of environment and factor own; Transformer also can cause environmental pollution; Need design driven circuit installing space, because of LED and drive circuit reflection, reliability and Efficiency Decreasing; Transformer loss 20-30% light efficiency causes the waste of the energy.
Summary of the invention
The object of the invention is to overcome above-mentioned technical deficiency, a kind of transformer drive circuit of not establishing is provided, such environmental effects is low, and reliability is high, and is pollution-free without light loss, causes the transless drive circuit series LED lamp of Efficiency Decreasing without heat.
The technical scheme that the utility model technical solution problem adopts is: a kind of transless drive circuit series LED lamp, comprise plug, bulb one and bulb two, the termination variable resistor and resistance one end that it is characterized in that bulb one, 2 ends of the other end plug of variable resistor and resistance; One end of another termination bulb two of bulb one, an end of the other end connecting resistance of bulb two, the other end of resistance is connected with 1 end of plug.
The beneficial effects of the utility model are: this utility model transless, need not the AC/DC transformer drive circuit, and such environmental effects is low, and reliability is high; Transformerless light efficiency loss; Pollution-free, without the hot Efficiency Decreasing that causes; Save material, cost is low, good energy-conserving effect, and the life-span is long.
Description of drawings
Illustrate with enforcement below in conjunction with accompanying drawing.
Figure is the circuit theory diagrams of transless drive circuit series LED lamp.
In figure: the J1-plug; PTC1, PTC2-variable resistor; R2, R3, R4, R5, R6, R7-resistance; AC/LED1-bulb one; AC/LED22-bulb two.
Embodiment
Embodiment, with reference to a kind of transless drive circuit of accompanying drawing series LED lamp, comprise plug J1, bulb one AC/LED1 and bulb two AC/LED2, it is characterized in that a termination variable resistor PTC1, the PTC2 of bulb one AC/LED1 and resistance R 4, R5 one end, 2 ends of the other end plug J1 of variable resistor PTC1, PTC2 and resistance R 4, R5; The end of another termination bulb two AC/LED2 of bulb one AC/LED1, the other end connecting resistance R3 of bulb two AC/LED2, the end of R2, R7, R6, resistance R 3, R2, R7, the other end of R6 is connected with 1 end of plug J1.Two lamp series connection are classified in this enforcement as, can carry out the series connection of a plurality of lamps by this way, just appropriately adjust to get final product on resistance quantity and numerical value.Plug J1 is inserted on the AC220V power supply.
