Abstract
A double-frequency acousto-optic electric signal sounding energy-saving pilot lamp is composed of a character display head of the semiconductor, a double-frequency acousto-optic signal generator and a sounding device. The utility model is characterized in that the display head of the pilot lamp is provided with two characters, two colors with double operating states, and simultaneously is provided with flashing and signal sounding functions. One pilot lamp of the utility model can display whether the power supply circuit and the device is on normal work or go out of order according to the operating states of the power supply circuit and the device. When the device goes out of order, the character displayed by the display head which is accompanied by signal sound flashes automatically. The utility model can substitute the two pilot lamps used traditionally on the electrical distribution switchboard.
Description
The utility model is that the board-like bifurcation electronics news of a kind of switch that supplies high and low voltage electric distribution and control panel to use are rung energy-saving indicating lamp.
The board-like pilot lamp of existing switch, it mainly is the incandescent lamp bulb of connecting various power by serial connection divider resistance or step-down transformer, determine the color of pilot lamp by the colour filter lampshade, usually with two of the same type and pilot lamp different colours indicate respectively circuit and equipment normally and fault state, wherein a lamp is operated in normal bright state, consumption of electric energy (is generally 8～30W) greatly, its illuminant colour is with the illuminant colour aberration is not little, not eye-catching, the disconnected maloperation that causes takes place to judge by accident because of bulb damages in incandescent lamp bulb life-span weak point often simultaneously.
The utility model is that a kind of duplex with two kinds of characters of demonstration, two kinds of colors of design is made the state bubble head, has the board-like bifurcation electronics news of the switch sound energy-saving indicating lamp that flicker and news are rung function simultaneously.It is except that can also being directly used in alarm terminal for using on high and low voltage electric distribution and the control panel.
The approach that the utility model solves above-mentioned task is: the board-like pilot lamp of a kind of improved switch, be made up of semiconductor character bubble head, bifrequency sound and light signal generator and microphone device.This pilot lamp can directly provide electric current about 0.01A, total power consumption about 2W to luminescent device by current-limiting resistance by civil power when showing normal operating conditions; Power supply is by flicker of bifrequency sound and light signal generator driven for emitting lights diode and loudspeaker sounding during device fails.This pilot lamp is because semiconductor character bubble head can show red a kind of character and green another kind of character respectively, therefore it is that a kind of duplex is made status indicator lamp, it can replace two pilot lamp that tradition is used, particularly when device fails, the character that bubble head shows can glimmer and accompany by specific news sound automatically (in multichannel monitors, but the news resonant of each branch road transfers preset to be distinguished), the staff can listen and watches timely failure judgement place by ear, thereby has shortened the time of fixing a breakdown.This pilot lamp have light emitting semiconductor device long advantage of low energy consumption of intrinsic life-span, the aberration of its illuminant colour and illuminant colour not is big, it is eye-catching directly perceived to show.
The utility model can be according to different occasion needs, design different character display, color, working power, installation bore, the board-like pilot lamp of switch, and need not change former designed lines and bore is installed.
Description of drawings the utility model embodiment:
Fig. 1 is that the board-like news of switch are rung the energy-saving indicating lamp longitudinal sectional view.
Fig. 2 is semiconductor character bubble head figure.
Fig. 3 is that the board-like news of switch are rung energy-saving indicating lamp electricity principle schematic.
Fig. 1 represents that the board-like bifurcation electronics news of switch sound energy-saving indicating lamp critical piece comprises: bubble head (1), main body box (2), circuit board (3), transformer (4), loudspeaker (5), modified tone potentiometer (6), handle cap (7) landing (8) connection terminal (a 9) bonnet (10).Bubble head is the shell of a plastic pressure forming, and its root puts in landing (8), revolve turn 90 degrees after, rely on handle cap (7) to be fastened on the switching motherboard.
Fig. 2 represents that the front surface of bubble head has the plastic compression plate (B) that is carved with specific character shape grid hole of a black, (C) be a printed circuit board, (several double-colored (tube core that refers to two different colors of same body the inside encapsulation) or single color LEDs (A) of arranging as required of top welding.This routine bubble head shows that T represents to lead to, D represents to break, and T partly need be with red, green dichromatic LED, and remainder only needs red or green single color LED, and these light emitting diode body heads stretch out grid orifice plate (B), and surperficial concordant with (B).The light emitting diode body is water white.Printed circuit board (PCB) (C) is by one three termination plug-in unit (E) place in circuit.
Fig. 3 represent civil power through control contact (the output switches of various sensors) as be added to the board-like bifurcation of switch news ring energy-saving indicating lamp connection terminals (9) 1 and 2 on, at this moment civil power provides electric current about 0.01A to be added to bubble head (1) by current-limiting resistance R to form on the one group of green or red light emitting diodes tube core of T shape, as normal bright operate as normal indication.During device fails, civil power changes and is added on connection terminal 2 and 3, at this moment power supply is through transformer (4), on one group of redness that drives that bubble head (1) forms by bifrequency sound and light signal generator or the green LED tube core flicker luminous, drive loudspeaker (5) sounding simultaneously.
Claims (2)
1, the board-like bifurcation electronics news of a kind of switch are rung energy-saving indicating lamp, it is characterized in that semiconductor character bubble head, bifrequency sound and light signal generator and microphone device that pilot lamp is made state by duplex combine.
2, the board-like bifurcation electric energy-saving of switch according to claim 1 pilot lamp is characterized in that the character graphics of being made up of two above light emitting diodes in the bubble head.
