Abstract
The utility model relates to an energy saving device for a gas discharging lamp, which mainly solves the problem of the energy saving of a lamp source. The energy saving device for a gas discharging lamp is mainly composed of an alternating current supply circuit, a voltage regulating executive circuit, a smoothing voltage regulating circuit, a timer circuit, a voltage comparing circuit, and a low voltage direct current circuit. When a lamp is started, the energy saving device supplies electricity to a lamp by the voltage of commercial power to ensure the starting of the lamp; when the lamp enters normal operation, the energy saving device automatically regulates voltage and provides the voltage for the lamp according to lower working voltage set in advance. Thus, twenty percent to forty percent of electric energy can be saved, and bright lamp light which is stable chronically can be obtained; the service time of the lamp can be extended two to four times. The utility model can be widely used in high power lighting lamps and places of dense lamp light.
Description
The utility model belongs to the saves energy device, and particularly a kind of gaseous discharge lamp is saved the general power electronic equipment of electricity.
As everyone knows, electric consumption on lighting is one of rich and influential family of various countries' power consumption, and China is no exception, and annual nearly nearly 10% electricity is used for illumination.In order to improve illumination; the conservation of power resource; various countries have formally proposed " Green Lighting Project " in succession; its main contents are: adopt efficient of low pollution light source, improve lighting quality, labor productivity and the energy and effectively utilize level, reach energy savings; reducing lighting expense uses; reduce the thermal power project construction, reduce the effusion and the discharging of harmful substance, reach the purpose of protection environment for human survival.The electric lighting device that relates in Green Lighting Project mainly contains: (1) development third generation high-intensity gas discharge lamp (HID), particularly metal halide lamp and high-pressure sodium lamp; (2) development Ф 26mm (T
8) tubule footpath fluorescent lamp; (3) adopt one end fluorescent lamp to replace incandescent lamp; (4) recommend PAR opening tungsten halogen lamp; (5) output and the single power thereof of restriction incandescent lamp, at present incandescent lamp is 8.2: 1 with the PR of fluorescent lamp, strives for reaching 2: 1 in several years, and limits the production of 150W and above incandescent lamp; (6) replace Inductive ballast with electric ballast.Can expect, over the next several years between, comprise that the gaseous discharge lamp of fluorescent lamp, sodium vapor lamp, metal halide lamp, mercury lamp will have a flourishing great development.But these lonely light discharge lamps generally have negative resistance charactertistic, need the ballast steady-working state, required operating voltage when promptly their starting resistor is higher than their operate as normal.By the curve 1 of Fig. 9 as can be seen, directly power with civil power, ballast can make lamp normally start, and enters operating state.Because this moment, lamp did not need very high voltage, thereby overvoltage will be inevitable.This superpotential appearance will make the characteristic control breakdown of lamp, initial hundreds of to 1,000 hours in lumen fraction descend about 15%, and the 40-50% that descends in afterwards 6,000 to 8,000 hours has wasted electric energy greatly.
The purpose of this utility model is the physical phenomenon according to the above-mentioned gas discharge lamp, design a kind of can mains-supplied when starting gaseous discharge lamp, and the gaseous discharge lamp electricity-saving appliance of the low voltage power supply that in steady-working state subsequently, can be close with its operating voltage, to solve saves energy, improve the operating state of lamp, prolong problem service time of lamp.
The new purpose of this practicality is achieved in that
The utility model mainly is made up of ac power circuit, pressure regulation executive circuit, level and smooth regulating circuit, timing circuit, voltage comparator circuit, low-voltage dc circuit.Wherein ac power circuit is connected with the comparison circuit of low-voltage dc circuit, level and smooth regulating circuit, pressure regulation executive circuit, voltage respectively; Low-voltage dc circuit is connected with voltage comparator circuit, pressure regulation executive circuit simultaneously; Level and smooth regulating circuit is connected with timing circuit, voltage comparator circuit, pressure regulation executive circuit and lamp load circuit again simultaneously; When lamp in when startup stage, provide operating voltage by low-voltage DC road direction voltage comparator circuit and pressure regulation executive circuit, timing circuit picks up counting, and the pressure regulation executive circuit is not driven with level and smooth regulating circuit, this moment, level and smooth regulating circuit was electrically communicated to the lamp load circuit with the city, 5./6. holding of voltage comparator circuit with 2./3. the two ends level is different, and obtain the driving of line voltage always; After lamp reaches operate as normal from startup, timing circuit finishes timing, output low level, drive pressure regulation executive circuit and level and smooth regulating circuit work, when level and smooth regulating circuit 2./3. terminal voltage be transferred to when consistent with the operating voltage of 5./6. end setting, voltage comparator circuit holds output LOW voltage, civil power disconnects with level and smooth regulating circuit, low-voltage dc circuit quits work, and the voltage of setting is kept to the lamp power supply that enters operating state always, starts up to next time.
The utility model is owing to adopted when starting gaseous discharge lamp with mains-supplied, and in steady-working state subsequently, the circuit structure of the lower voltage that is close with its operating voltage is provided to lamp, thereby for using at the monomer power of occasions such as road, tunnel, market, bank, goods yard, hospital, workshop, industrial canopy storehouse, harbour, airport, shopping center, stadiums, heavy construction place, the public illumination gaseous discharge lamp of big (400W, 1000W), though and monomer power is little, but use intensive fluorescent lamp, all have following advantage:
(1) reliable operation, the mean free error time is long;
(2), use the utility model can save the electric energy of 20-40% for dissimilar gaseous discharge lamps and dissimilar ballasts;
(3) can prolong the service time of lamp more than 3-4 times, and reduce the effusion of harmful substance, protect environment, reduce maintenance cost and lighting expense and used.
Actual measurement shows, when being adjusted to when saving electric power and being 25-35%, in incipient hundreds of hours of lamp, outside lumen fraction slightly reduced, in the operating time thereafter, the decay of luminous flux was very slow, shown in the curve among Fig. 92.As seen using gases discharge lamp electricity-saving appliance is not only saved electric power, and in the operating time of most of lamp, compares with the lamp of directly powering with civil power, can obtain brighter more stable light.
