Though adopt single led or osram lamp use in parallel, be combined into decorative chain, do not influence the luminous of whole group LED or osram lamp in the time of can solving a LED or osram lamp open circuit, but LED or osram lamp quantity in parallel are many more, the operating current that needs is just big more, that is the operating current IF * LED of the electric current I of always working=each LED or osram lamp or the total quantity N of osram lamp.For example: by the LED lamp string that 35 White LEDs compose in parallel, the specification of each White LED is 3.2V/0.02A, and the operating voltage that offers LED lamp string is 3.2V, but operating current then is 0.7A, i.e. 0.02A * 35=0.7A; As forming decorative chain by 35 osram lamps, each osram lamp specification is 3.2V/0.08A, and the operating voltage that offers decorative chain is 3.2V, and then operating current then is 2.8A, i.e. 0.08 * 35=2.8A.It is 3.2V that the operating voltage of these two kinds of lamp strings and operating current convert the operating voltage AC120V of family expenses alternating voltage or appointment to voltage by a rectifier, the electric current of 0.7A and 3.2V, the electric current of 2.8A.When LED in the lamp string or osram lamp open circuit occurred or be moved out of, then other 34 LED or osram lamp still can be normally luminous, can continue to provide illumination and decorative effect is provided.The lamp string that these a plurality of LED or osram lamp compose in parallel, open circuit appears in a LED or osram lamp or do not influence the normally luminous of other LED or osram lamp when being moved out of though can solve on the lamp string, but the rectifier that this lamp string relates to need become household voltage or assigned work voltage transitions the working power of low-voltage, high electric current, on circuit design, bring serious difficulty for the designer, equally also increase the cost of product, be unfavorable for inter-industry competition.
Summary of the invention
The technical problems to be solved in the utility model provides a kind of decorative chain, can either make LED in the lamp string or osram lamp open circuit occur or when being moved out of, then other LED or osram lamp still can be normally luminous, can make the simplicity of design of rectifier again, reduce product cost.
In order to solve the problems of the technologies described above, a kind of decorative chain of the present utility model, comprise attaching plug, described decorative chain has lamp string input and lamp string output, be in series with some illuminators between described lamp string input and the lamp string output, the two ends of described illuminator all are parallel with Zener diode.
As improvement of the technical scheme, described illuminator is osram lamp, LED or both and usefulness.
As further improvement in the technical proposal, described decorative chain also comprises alternating current is converted to galvanic rectifier, the positive pole of described rectifier is connected with lamp string input, the negative pole of rectifier is connected with lamp string output, the P district of Zener diode is connected with the negative pole of rectifier, and the N district of Zener diode is connected with the positive pole of rectifier.
Be parallel with filter capacitor between the positive and negative electrode of described rectifier.
The beneficial effects of the utility model are: this decorative chain is owing to adopted said structure, when LED in the lamp string or osram lamp open circuit occurs or are moved out of, electric current can pass through its corresponding Zener diode, the LED or the osram lamp that guarantee other still can be normally luminous, do not influence the illumination and the decorative effect of decorative chain, and can reduce the design difficulty of rectifier, reduce product cost.
