Abstract
A signal lamp for preventing wrong lighting mainly comprises an LED, a branch circuit is connected in parallel at two ends of the LED, and the branch circuit comprises a resistor R or the resistor R and a capacitor C which are connected in parallel. The signal lamp has the advantages that the LED does not emit light within the range of rated voltage value when the voltage is increased by 15%, and no wrong lighting of the signal lamp is ensured.
Description
Technical field: the utility model relates to distribution field signal lamp, the anti-error bright signal lamp of particularly a kind of LED.
Background technology: in switchboard cabinet and the casing signal circuit, all use the LED energy-saving signal lamp, in actual applications, owing to reasons such as electromagnetic induction and electric leakages, make the signal lamp two ends that should not give out light originally have ten volts of above voltages, it is luminous that this voltage begins LED, is mistaken as signal lamp easily and is in bright state.
Summary of the invention: the purpose of this utility model is to overcome the prior art diode (LED) signal lamp of giving out light and has the bright defective of mistake, provides a kind of signal accurate, errorless bright signal lamp.
The technical solution of the utility model is a kind of anti-error bright signal lamp, mainly constitutes by LED, and diverter branch in parallel at the LED two ends, diverter branch is composed in parallel by resistance R or resistance R and capacitor C.
The utility model has the advantages that LED is not luminous in voltage increases 15% load voltage value scope, it is bright to guarantee that mistake does not take place signal lamp.
Description of drawings: accompanying drawing 1 is anti-error bright signal lamp embodiment 1 circuit diagram of the utility model.
Accompanying drawing 2 is anti-error bright signal lamp embodiment 2 circuit diagrams of the utility model.
The specific embodiment: the utility model further specifies as follows in conjunction with specific embodiments referring to accompanying drawing.
Embodiment 1, a kind of anti-error bright signal lamp, mainly constitute by LED, physical circuit is referring to accompanying drawing 1, and it is connected in series successively by resistance R 1, LED, resistance R 2, diverter branch 1 of being made up of resistance R in parallel at the LED two ends.Embodiment 1 is applicable to direct current or alternating current circuit.
Among embodiment 1 and the embodiment 2, by a shunt resistance in parallel or capacitance-resistance diverter branch at the LED two ends, make signal lamp in voltage increases 15% load voltage value scope, the electric current that flows through LED is being given out light below the door current value, guarantees that signal lamp does not work.
Claims (1)
1. an anti-error bright signal lamp mainly is made of LED, it is characterized in that LED two ends diverter branch in parallel, and diverter branch is composed in parallel by resistance R or resistance R and capacitor C.
