Abstract
The utility model discloses a novel decorative LED lamp string which is composed of a plurality of LEDs which are connected in series or in parallel, and a variable resistor with an appropriate resistance value is connected in series with the series circuit or the parallel circuit of the LEDs. The limitation of LED lamp products, which is caused by the self work voltage, can be solved by the utility model, lamp products with any quantity of LEDs can be made by the method of increasing resistors under the condition of any voltage.
Description
Technical field
The utility model relates to person in electronics, a kind of specifically New LED decorative chain.
Technical background
Manufacture the production technology of string shape LED lamp decoration product at present, be subjected to the restriction of LED self operating voltage, the serial connection lamp number of manufacturing has been subjected to certain restriction, can not satisfy the demand in market.
The utility model content
The utility model proposes a kind of New LED decorative chain, at the problem of above-mentioned appearance, solved the limitation that the LED lamp decoration product is subjected to self operating voltage, by increasing the mode of resistance, reach and under the situation of any voltage supplied, to make the lamp decoration product of any LED quantity.
The technical solution of the utility model
A kind of New LED decorative chain is contacted or is formed in parallel by a plurality of LED light emitting diodes, it is characterized in that: the resistance of having contacted in the serial or parallel connection circuit of LED light emitting diode.
Described a kind of New LED decorative chain is characterized in that the bunchiness of connecting after the parallel connection of per two LED light emitting diodes.
Described resistance is variable resistor, and the computing formula of its resistance is as follows: R=(V-UaN)/I, and wherein R represents variable-resistance resistance; V refers to that the voltage of working power can be direct current, also can exchange; U refers to single led work rated voltage, and its basic parameter is 2.5V; A refers to the coefficient value of LED operating voltage, and the coefficient of different colours or brightness LED can be different, and coefficient value is between 0.8～1.8; N refers to the lamp number that will make; I refers to the rated operational current of LED, and it is 0.02 ampere of a constant.
If directly LED is applied in the lamp string, directly insert to use the 110-220V circuit, must there be the LED of some could satisfy the rated voltage requirement of each LED.
The utility model carries out step-down by the mode that inserts resistance.By inserting the resistance of divider resistance and setting divider resistance, LED lamp string can be designed to any amount of lamp string, and inserts the civil power of different voltages.
The utility model adopts connect the then mode of bunchiness of single group LED parallel connection, under the situation that any one LED damages, Bing Lian LED still works with it, extremely important when design LED operating current, consider his maximum operating currenbt and the ability of overcurrent here, so the LED maximum operating currenbt of the utility model selection 70% is used as its operating current.
Because the utility model adopts paired LED design in parallel, not luminous as one of them LED, but whole lamp string still works, and the user can be very easy to find idle LED.
Effect of the present utility model
The LED number of the serial connection that the utility model is made can not limited by voltage, can satisfy different occasions and client's needs.
Description of drawings
Fig. 1 electrical block diagram of the present utility model.
The specific embodiment
Referring to Fig. 1.The operating voltage of producing string shape lamp decoration product is 120V, the LED light emitting diode that choosing is red, its coefficient value is 0.8, makes series connection of 35 lamps, the resistance R that will seal in the lamp decoration product=(V-UaN)/I=(120-2.5 * 0.8 * 35)/0.02=2500 ohm.According to different LED light emitting diodes, its coefficient value is different, and lamp number as required calculates resistance.
