Abstract
The utility model relates to an energy-saving indicating lamp which can represent whether an industrial electrical device has a power supply or not and represent the breaking state of a circuit breaker. The utility model is characterized in that after voltage reduction, the power supply is connected to a low-voltage luminous tube. Compared with the existing indicating lamp which is an incandescent lamp, the utility model has the advantages that the energy consumption is reduced by more than 80%, and the service life is increased by more than twenty times.
Description
The utility model relates to a kind ofly has non-transformer and breaker to cut-off the indicator lamp of state about electrical equipment.
The indicator lamp that uses on the existing industrial electrical installation mostly is incandescent lamp.The CN87206888 patent disclosure a kind of " exchanging industrial signal lamp ", this indicator lamp is formed with capacitances in series after by bi-directional voltage stabilizing diode and small electric bulb parallel connection again, this indicator lamp operating voltage still is bigger supply voltage, the life-span of indicator lamp is also shorter, and can only work in exchange status.
The purpose of this utility model is a kind of little power consumption of design, the energy-saving indicating lamp that the life-span is long.
The utility model is achieved in that
A kind of energy-saving indicating lamp relates to operating circuit and indicator lamp, it is characterized in that circuit part inserts indicator lamp by reduction voltage circuit and after step-down load circuit forms, and its indicator lamp is a luminous tube.
Further scheme is that reduction voltage circuit is a transformer.
Further scheme is that reduction voltage circuit is by R
1, R
2The bleeder circuit that constitutes.
Because the utility model has adopted the low-voltage luminescence pipe, under same brightness, 20 percent of the not enough existing indicator lamp energy consumption of its energy consumption, its life-span is more than 20 times of the existing indicator lamp life-span.
Fig. 1 is the circuit diagram after the utility model adopts the transformer step-down.
Fig. 2 is that the utility model works in the circuit diagram that exchange status adopts bleeder circuit.
Fig. 3 is that the utility model works in the circuit diagram that dc state adopts bleeder circuit.
Below, in conjunction with the accompanying drawings the utility model is described further.
As Fig. 1 and Fig. 2, load circuit is formed in parallel by two groups of circuit that are in series with 3 luminous tubes formations, and only one of its reduction voltage circuit is a transformer, and another is by R
1, R
2The bleeder circuit that constitutes.
As Fig. 3, be under the situation of direct current at power supply, reduction voltage circuit is by R
1, R
2The bleeder circuit that constitutes, load circuit is in series by 5 luminous tubes.
