Abstract

The utility model relates to an electroluminescence lamp which comprises a light-emitting component composed of one to one hundred semiconductor luminous bodies connected in series. Both ends of the light-emitting component are respectively connected to a rectifying electronic circuit, and are again connected to both poles of an electrical contact through a depressurization capacitance. Because the utility model does not have a resistive load, the energy consumption is low. In addition, because of the light-emitting component belonging to a cold light source, the life is particularly long and is scores of times as long as that of an ordinary lighting lamp. Accordingly, the utility model belongs to an idea lamp particularly used as a civil electroluminescence lamp.

Description

A kind of electroluminescent lamps

The utility model relates to a kind of be used in the buildings or other needs the electroluminescent lamps of low-level lighting occasion, is suitable for especially comprising that an electrical contact that joins with power supply and one place the made lamp of case in it with luminous component.

Electroluminescent lamps of the prior art mainly is made up of the electrical contact, case and the luminous component that join with power supply.And luminous component generally all is lean on tungsten filament red-hot luminous, or luminous by gas discharge.These two kinds of luminous components all belong to resistive load, and the person's character that resistive load all has the obstruction electric current to pass through, will generate heat when electric current flows through to consume bigger comparatively speaking energy.The existing way that cuts down the consumption of energy to by by the red-hot alight of tungsten filament be the diameter that reduces tungsten filament, reduce electric current and reduce power, owing to hitting the also minimizing thereupon of ability and anti-volatilization ability in its anti-current of diameter that reduces tungsten filament, make become shorter original serviceable life, generally all do not reach 1,000 hours with regard to very short lamp; And for the lamp of making by gas discharge principle, as high-frequency electrodeless fluorescent lamp etc., its solution is the power frequency electricity to be become that high-frequency electrical is come for its gas discharge and luminous with electronic circuit, thereby improve luminescence efficiency, cut down the consumption of energy, but its cost cost is very high, and all must have relatively many annexes to exist.

For addressing the above problem, patent that Chinese patent CN2230466Y has announced a kind of " being directly used in the light emitting diode indicator of alternating current ".It is serially connected mutually separately with two groups and then the light emitting diode of reverse parallel connection as luminous component, and connect between light emitting diode and the AC power decompression capacitor and current-limiting resistance, discharge resistance in parallel on decompression capacitor.Because it has adopted capacitance-resistance electronics reduction voltage circuit, can cut down the consumption of energy with significantly measuring.But be used for AC power, the serial connection of resistance must produce pressure drop and generate heat, and what also will consume certain energy.In addition, can only utilize half energy in the alternating current with the electroluminescent lamp of this circuit production, promptly Zheng Xianbo positive half cycle or negative half period just can be finished as the luminotron that will utilize second half energy to waste twice again, so it is not optimal electroluminescent lamp.

Task of the present utility model provides a kind of electroluminescent lamps, and it can cut down the consumption of energy to greatest extent, improves the power factor of electrical network, and arranged long serviceable life.

For finishing above-mentioned task, luminous component of the present utility model is made up of 1～100 semiconductor light emitting body that is serially connected; The two ends of luminous component and rectified current electronic circuit join, and join with the two poles of the earth of electrical contact through decompression capacitor again.Owing to adopted capacitance decompression rectified current electronic circuit, there is not resistive load in the circuit, consumed energy is extremely low, in can also be effectively and in the electrical network as the induction reactance of generations such as coil, ballast resistor and the transformer of common electrical kilsyth basalt, so can improve the power factor of electrical network, in addition, rectification circuit adopts the full-bridge type rectification circuit, can make full use of energy sinusoidal wave in the alternating current.

Above-mentioned semiconductor light emitting body can be made up of the light-emittingdiode of super brightness.

Above-mentioned rectification circuit is made of full-bridge type rectified current electronic circuit.

Because the utility model has adopted capacitor step-down rectifier circuit, and luminous component adopts the diode luminophor, and it does not have resistive load, so energy consumption is especially little.In addition since the diode luminophor to belong to its life-span of cold light source long especially, it is tens times of common electrical electroluminescent lamp, so it is a kind of very desirable particularly civilian electroluminescent lamps.

The utility model is described in further detail below in conjunction with drawings and Examples.

Accompanying drawing 1 is a synoptic diagram directly perceived of the present utility model;

Accompanying drawing 2 is circuit theory diagrams of the present utility model.

Provided the structure of an embodiment of the utility model among Fig. 1, it comprises an electrical contact 4, is provided with two electrodes 3 on this electrical contact, and it can directly join with power supply.Electrical contact 4 is similar to the lamp holder of incandescent lamp in the prior art, can be screwed in and get final product energized on the power socket.Certainly electrical contact 4 also can be made into other shape, and as two board-like skewer heads or different shapes such as skewer mouth or screw socket etc., these all are prior aries, no longer describes in detail here.Case 1 top is fixed on the lower end of electrical contact 4, and luminous component 2 is installed in it.Case 1 can be made by material transparent, as glass, plastics, also can add colored as red, green, orchid etc., can make light bright in luster like this.

Accompanying drawing 2 has provided circuit theory diagrams of the present utility model, and it is connected with rectification full-bridge Q by a decompression capacitor C and forms capacitance decompression full-bridge type rectified current electronic circuit, and its output terminal is connected with the light-emittingdiode D that is connecting one by one.This circuit can change the positive and negative half-wave of electrical network into fully can supply the required direct current of semiconductor light emitting diode D, so can improve the efficient of light-emittingdiode D.Here used light-emittingdiode D is the super brightness light-emittingdiode.The 1-100 that is serially connected among Fig. 2 light-emittingdiode D is the stack for brightness, and the number of light-emittingdiode D is decided on the purposes of this electroluminescent lamps.When this lamp is used for domestic lighting, during required low-light level illumination, the number of light-emittingdiode D get final product between 1～40, when this electroluminescent lamps usefulness in public, when particularly being applied in the illumination that is similar to giant-screen, the number of light-emittingdiode D is about 10～100.The utility model can be done desk lamp, pendent lamp, floor lamp, wall lamp etc., and particularly the illumination of the public occasion of buildings is more suitable.
