Abstract
The utility model belongs to the technical field of LED (Light-Emitting Diode) lamp strings, and relates to an LED lamp string with consistent brightness. The LED lamp string comprises a plurality of LED lamps connected via an electric wire, wherein after all LED lamps are connected in parallel in sequence via the electric wire, the anode of a first LED lamp is electrically connected with the anode of a power supply, the cathode of a last LED lamp is electrically connected with the cathode of the power supply, and a protective resistor is connected in series to the electric wire for connecting the cathode of the last LED lamp with the cathode of the power supply. The LED lamp string has the advantages that the quantity of lamp caps can be expanded to 1,000 or more, a first bulb and a last bulb are of consistent brightness, resistance existing in the electric wire can be utilized, and selection of the resistor R is facilitated; and the LED lamp string is suitable for decorating lamp strings.
Description
Technical field
The utility model belongs to LED lamp string technical field, and the brightness of refering in particular to a kind of all LED lamps is consistent LED lamp string all.
Background technology
Fig. 1 has provided that input power is DC3V-6V(contains battery as power supply in the prior art) the lamp string that is connected in parallel, the problem that this structure exists is: the one, be subjected to the impact of electric wire 10,11 resistance, LED lamp quantity in parallel is restricted, and is no more than at most 200; The 2nd, when the lamp holder number of LED lamp reached some, the LED lamp of first LED lamp and centre and the brightness of last LED lamp were obviously inconsistent.
Summary of the invention
The purpose of this utility model provide a kind of before, during and after the equal consistent LED lamp string of brightness of all LED lamps.
The purpose of this utility model is achieved in that
The LED lamp string that brightness is consistent; comprise and connecting with electric wire and several LED lamps; after all LED lamps are connected in parallel with the electric wire order; the positive pole of first LED lamp is electrically connected with positive source; the negative pole of last LED lamp is electrically connected with power cathode, being connected with being connected in series with protective resistance on the electric wire between the negative pole of last LED lamp and the power cathode.
Above-mentioned protective resistance is variable resistor.
