Abstract
The utility model relates to a luminescent diode signal lamp which comprises a luminescent diode body. The utility model is characterized in that the luminescent diode body is connected with a resistance in series, the two ends of the resistance are connected with a voltage stabilizing diode in parallel, and the resistance is connected with a resistance in series. The utility model has the advantages that luminescent diodes with long service life and low power consumption can take the place of incandescence lamps and can be use as signal pilot lamps.
Description
Technical field
The utility model relates to a kind of signal source, particularly a kind of light-emitting diode signal source.
Background technology
In field of electronics, can use some incandescent lamps at present usually and do signal optical source; the not only existence of shows signal of signal source this moment; the size of also wanting shows signal is the variation of signal optical source light and shade power; but because service life of incandescent lamp is shorter; power consumption is big; the needs of incompatible development in the use, the light-emitting diode long with the life-span, that power consumption is little is then owing to voltage---and light intensity curve and incandescent lamp be inconsistent to be difficult to the effect that reaches identical.
Summary of the invention
The purpose of this utility model is to solve the light-emitting diode long with the life-span in the prior art, that power consumption is little to replace incandescent lamp to do signal source, because voltage---and the inconsistent and problem that can't use of light intensity curve.Technical solutions of the utility model design light-emitting diode signal source, comprise light-emitting diode group, current-limiting resistance, it is characterized in that: light-emitting diode group is serially connected with at least one light adjusting circuit, light adjusting circuit is connected in series current-limiting resistance again, light adjusting circuit is made of a voltage stabilizing didoe resistance in parallel, and light-emitting diode group has a plurality of light-emitting diode series connection back formation in parallel.The utility model has the advantages that and light-emitting diode group long with the life-span, that power consumption is little to replace incandescent lamp to make signal optical source.
Description of drawings
Accompanying drawing 1 is a circuit diagram of the present utility model,
Accompanying drawing 2 is a voltage of the present utility model---light intensity curve figure,
Accompanying drawing 3 is a plurality of light adjusting circuit schematic diagram of the present utility model,
Comprise light-emitting diode group 1, current-limiting resistance 2 among embodiment Fig. 1, it is characterized in that: light-emitting diode group 1 is serially connected with at least one light adjusting circuit 3, light adjusting circuit 3 is connected in series current-limiting resistance 2 again, light adjusting circuit 3 is made of voltage stabilizing didoe 4 resistance 5 in parallel, it is characterized in that: light-emitting diode group 1 has a plurality of light-emitting diodes 6 series connection backs formation in parallel.During use, when input voltage is low, voltage-stabiliser tube diode 4 does not reach the voltage stabilizing value, the series connection that the characteristic of circuit shows as resistance 2 and resistance 5 is connected in series light-emitting diode group 1 again, and when input voltage increased, voltage-stabiliser tube diode 4 reached the voltage stabilizing value, the characteristic of circuit shows as resistance 5 and is connected in series with light-emitting diodes body 1, can approach the voltage of incandescent lamp---light intensity curve, many group light adjusting circuits 3 of also can connecting then can improve matching voltage---the precision of light intensity curve greatly.
