Description
Technical field
The utility model is about a kind of illuminator, the illuminator in its espespecially a kind of changeable supply operating voltage source.
Background technology
In environmental consciousness surging epoch now, the exploitation of the energy and consuming is paid attention to more.For energy resource consumption aspect, be main consideration with electrical energy saving again, cover traditional electric energy production process and can consume a large amount of environmental resource, and the use of electric energy, then can cause environmental pressure.In addition, national governments, for promoting public and social interest, take tune to rise electricity price measure more, to increase state revenue and expenditure, also indirectly impel power customer's independence to manage power consumption, reach the effect of environmental protection and energy saving.Therefore power consumption is as can be effectively controlled, makes the consumption of electric energy reach maximal efficiency, avoid unnecessary waste, except industrial economy benefit can be made to increase, to the cost management of businessman, also there is suitable help.
For extending mankind's activity time and increasing operational environment, lighting apparatus be daily in can not obtain scarce thing, at present conventional illumination with bulb or fluorescent tube for principal light source, even if only those devices still have its shortcoming through repeatedly improveing, wherein bulb is luminous with tungsten filament, photoelectric conversion efficiency is low, most energy more consumes at heat energy, therefore power consumption is high, reaction damages slowly or easily, and for making electronics mutually clash into generation light in fluorescent tube, needs to fill mercury gas, only mercury pollutes environment is unavoidable, is unsuitable for environmental protection application.Replace the mainstream technology of conventional bulb or fluorescent tube, the highest with light-emitting diode (Light-Emitting Diode:LED) cry, it utilizes electronics mobile characteristic producing light in semi-conducting material energy rank, have that power consumption is low and efficiency is high, again not like conventional bulb with filament light-emitting, therefore long service life and not fragile, or fill mercury gas and cause substantial pollution to environment, widely uses light-emitting diode and replaces conventional lamp system and point the day and await for it.
Current most light fixture specification is all formulated by most manufacturer is unified, for making light-emitting diode user without the need under changing lighting apparatus situation separately, the application of light-emitting diode is mainly coordinate known light fixture specification, by most light-emitting diode in serial or parallel connection mode, be arranged on lamp socket, form a light fixture.Ge Jia manufacturer is according to its application target and environment again, arranges light-emitting diode string or quantity in parallel is inconsistent in every lamp interior.Such as, a current light-emitting diode rated voltage about 3 ~ 4 volts, multiple light-emitting diode serial or parallel connection is become a light fixture by system of manufacturer, and this light fixture can the rated voltage being suitable for 110 volts, family that makes of serial or parallel connection again.Thus, it is namely different that each manufacturer produces the required voltage consumed of light fixture, make the light fixture that the light-emitting diode of different pattern or varying number is formed, required voltage is different, user as using different lamps simultaneously, then needs the power supply unit of various light fixture, if the improper application of power supply unit, light fixture may be caused to burn, or the situation such as brightness of illumination is not enough.Now, therefore, the power supply unit of different demand must be carried respectively, for different location or at any time mobile use the user of those light fixtures be one to bear greatly.
For solving the problem, in known techniques, providing a kind of light fixture, arranging a luminous lamp strip, luminous lamp strip comprises multiple light-emitting diode, and this light fixture comprises: a driver module, a housing, a lampshade and lamp socket.Driver module comprises a driver element and a specification identification unit, and the specification data that driver element corresponding specification identification unit obtains provides the electronic environment of specific electronic characteristics to give luminous lamp strip, makes luminous lamp strip luminous.Luminous lamp strip is arranged between housing and lampshade, and be electrically connected driver module via lamp socket, and wherein, foregoing metrics data system obtained by specification identification unit self-luminescent lamp bar.By the specification identification unit be arranged in light fixture, obtain the specification data be stored in the specification storage element of luminous lamp strip, to pick out the characteristic electron of luminous lamp strip and/or the luminescence component in it, thus the electronic environment meeting luminous lamp strip characteristic electron used is provided, make luminous lamp strip luminous.Only the light fixture of this kind of method dependence specification identification unit identification different size, need arrange specification storage element in addition, cause extra power consumption or light fixture space.
A kind of LED control circuit of another known techniques system, be applicable to control one light-emitting diode lamp tube, this light-emitting diode lamp tube comprises multiple LED light string, wherein this light-emitting diode lamp tube preferably maximum input voltage be no more than 70 volts and the lamp string number of LED light string is better be limited to 4 strings within.This LED control circuit comprises multiple diode, a protective circuit, multiple constant-current circuit and a diverter switch.The positive pole of each diode connects the output of single LED light string.Protective circuit is connected to the negative pole of each diode, and when having light-emitting diode to occur short circuit during the input terminal voltage of this light-emitting diode lamp tube is higher than a critical value or this light-emitting diode lamp tube, this protective circuit exports a switching signal.Each constant-current circuit connects the output of single LED light string, and control this constant-current circuit according to a switch controlling signal and whether work with and then control this light-emitting diode lamp tube and whether work, and control the brightness of this light-emitting diode lamp tube according to a dimming control signal.Diverter switch does not affect this switch controlling signal when not receiving this switching signal, and controls this light-emitting diode lamp tube when receiving this switching signal by this switch controlling signal and do not work.Said method utilizes constant-current circuit, each LED light string can be worked, and control brightness, only the method is for avoiding the excessive damage of voltage, it limits lamp string maximum voltage for being no more than 70 volts, thus, if user needs more lamp string, use more than 70 volts, the method and infeasible.
Therefore, known techniques is for the operating voltage of light fixture, cannot accurately grasp, especially when light fixture quantity is for knowing, the selection of relative power supply device is with regard to particular importance, as only driven whole illuminator with a kind of power supply device, when power supply device cannot work, namely illuminator cannot operate.In addition, when power supply device replys normal work, the rear end light fixture that maximum current may make instantaneously burns, therefore is necessary to arrange at power supply device and lamp locker the equipment avoiding problems to occur.
