Abstract

The utility model discloses a capacitive type luminous diode indicator lamp, which comprises a lamp body and concrete circuits. The utility model is characterized in that two groups (each group is provided with more than two LEDs) of LEDs are connected in succession, then are reversely connected in parallel, and are connected with a capacitor in series, wherein, both ends of the circuit are connected into an AC network. The utility model has the characteristics of small volume, light weight, high efficiency, energy saving, long service life and low cost, can be widely used for a control table of an electrical panel of high and low pressure, a planeside control box and a mimic panel, and can also be applicable to situations, such as dance halls, show windows, etc., when made into festoon lamps.

Description

Capacitive type luminous diode indicator lamp

The utility model belongs to the lighting device of using as signal, further is meant a kind of indicator light.

At present, the indicator light that uses in the AC distribution net generally has two kinds, be incandescent lamp and neon lamp, they are low voltage bulb, and the voltage of power supply network is generally 110V, 220V, 380V, when stating bulb in the use, necessary first step-down, its way can adopt resistance step-down or transformer step-down; Because the power consumption of incandescent lamp own is big, adopt the resistance step-down, power consumption reaches 8-15W, adopts the transformer step-down also to have more than the 2W, though and the power consumption of neon lamp own is little, also between 0.66-1.14W, service time one is long for power consumption after the step-down, total power consumption is also very considerable; Above-mentioned bulb service life short (generally at 1000-1500 hour) needs often to change; Though use transformer step-down power consumption to reduce, total power consumption is still big, and volume is big, Heavy Weight, need precious metal materials such as a large amount of copper materials and silicon steel sheet, the cost height, and luminous a little less than.Also have a kind of nonpolarity energy-efficient indicator light, though also be to adopt light-emitting diode as light emitting source, it needs rectification circuit, and light-emitting component is worked under dc state, and cost is still high.

The purpose of this utility model provides the indicator light that a kind of body is little, amount is light, efficient, energy-conservation, long-lived, inexpensive.

Technical solution of the present utility model is: light-emitting component of the present utility model is a light-emitting diode, and it comprises lamp body and circuit.Lamp body can utilize existing product, but also otherwise designed; Its circuit connecting relation is, by suitable separately back (every group light-emitting diode is more than the two) reverse parallel connection again of going here and there of two groups of light-emitting diodes, connect with a decompression capacitor again, the power input of the two ends of circuit for joining with AC network, because alternating current is through the process of electric capacity charge and discharge, the positive and negative half-wave that makes electric current can both obtain complementation in arbitrary group of light emitting diode string and operate as normal reaches purpose of indicating.

Below in conjunction with drawings and Examples the utility model is described in detail.

Fig. 1 is the lamp body surface structure schematic diagram of the utility model embodiment 1;

Fig. 2 is the line map of the utility model embodiment 1;

Among the figure, the 1-lampshade, 2-decorates thread cap, 3-plastic washer, 4-fastening screw filament plate, 5-lamp socket, 6-screw rod sleeve pipe, 7-bonnet, 8, the 9-screw that goes between, C-electric capacity, D1, D2, D3, D4, D5-light-emitting diode.

Embodiment 1: referring to accompanying drawing 1, utilize existing lamp body shell, consider the capacity of lampshade (1), 5 homochromy light-emitting diodes (D1-D5) are arranged in the lampshade (1) quincunxly, referring to Fig. 2, wherein with the suitable respectively string of two groups of light-emitting diodes (D1-D2, D3-D5), with one group of light-emitting diode (D1-D2) and another group light-emitting diode (D3-D5) reverse parallel connection, connecting one can only anti-220V again, capacity is the decompression capacitor C of 0.1 μ f, in two ends (8,9) the incoming transport electrical network with circuit, can become an indicator light.As required, lampshade (1) can be divided into red, green, yellow three looks, and light-emitting diode also has red, green, yellow three kinds, after the corresponding configuration, can make colour code clear, and the parameter that its luminous intensity can suitably be adjusted capacitor C satisfies;

Embodiment 2: 9 light-emitting diodes are arranged in the light trough of the square indicator light of cordwood system type mimic panel, are divided into two groups, 4 of one group of strings, 5 of another group strings, a decompression capacitor, the method connection of press embodiment 1;

Embodiment 3: 22 light-emitting diodes is arranged in one in addition in the light trough of the indicator light of design, is divided into two groups, and 11 of every group of strings, a decompression capacitor, the method for press embodiment 1 connects, and can make color lamp usefulness.

Light-emitting component of the present utility model is owing to adopt light emitting diode, and it and existing incandescent lamp and neon lamp relatively have efficient, energy-conservation, long-lived advantage, by the design of exquisiteness, can make the indicator lamp that volume is little, in light weight, cost is low; Compare with electrodeless high efficiency energy-saving indicator lamp, saved rectification circuit, cost is low, can be widely used on high and low voltage electric distribution dish, console, the other control box of machine and the mimic panel, makes color lamp and also is applicable to the occasions such as dance hall and shopper window.
