Abstract
The utility model relates to an electric switch. The switch is arranged inside with an appropriate electric condenser C, and a florescent lamp circuit is connected with the C in series through selection, making the operating current of the tube lying near the corresponding number value of the highest light effect, achieving the purpose of light modulating and power saving. The switch can take the action of an ordinary switch. When modulating light with the switch, because the light effect is improved, compared with a florescent lamp with conventional circuit and the same luminous flux output, the power can be saved about 24%. Besides, the utility model has the advantages of slowing senescence of the tube, improving luminous stability, improving supply mains power factor and reducing the installation cost. The utility model can also be used for the power regulation of filament lamps and electric fans.
Description
Adjusting brightness of fluorescent lamp/battery-conserving switch belongs to a kind of electric switch.
The brightness of fluorescent lamp and its operating current are approximate proportional, but luminous efficiency is non-linear relation with operating current, sees accompanying drawing 1.In the conventional some lamp driver (seeing accompanying drawing 2), have bigger luminous flux (brightness) output, its operating current I for making fluorescent lamp
1Pairing numerical value I when the highest far above luminous efficiency
0, add that the loss on ballast L this moment is bigger, so with the bigger waste of existence of lighting a lamp of this conventional line.
The purpose of this utility model is exactly by whether selecting the suitable current limiting element (capacitor C sees accompanying drawing 4) of series connection in above-mentioned conventional line, to reduce the operating current of fluorescent tube, makes it to be in fluorescent tube light efficiency pairing I when the highest
0Near the value, and realize light modulation, economize on electricity; Or make fluorescent tube line work routinely.
In the frame of broken lines, be exactly design of the present utility model in the accompanying drawing 5.In a SP3T K switch is arranged, its moving contact 0 can be respectively connected with fixed contact 1,2,3, capacitor C is that light modulation (economize on electricity) element R is the bleeder resistance of C, resistance is got hundreds of K Ω, A, B are binding post.With the stay-supported is example, when moving contact places 3, and circuitry cuts, lamp goes out.When moving contact is transformed into 1 by 3 (the stay-supported switch can only be changed by this order), circuit is connected, and this moment, fluorescent lamp was in conventional line utilization state, equivalent electric circuit such as accompanying drawing 3.Behind the normal build-up of luminance of lamp, when needing light modulation (economize on electricity), draw a pull-down line again, moving contact just is transformed into 2 by 1, with the capacitors in series place in circuit, plays current limliting (light modulation) effect, and the utilization state just economizes on electricity this moment.Equivalent electric circuit such as accompanying drawing 4.
Power savings, straight pipe type fluorescent lamp with ∮ 38mm standard design is an example, it for rated power 40 watts YZ40RR fluorescent tube, when capacitor C gets 2.1 μ F, the actual measurement of its output light flux is 1435 lumens, is equivalent to the luminous flux output (1400 lumen) of 30 watts of YZ30RR fluorescent tubes of conventional line work, but power consumption have only its 75.4%, save 24.6%, see attached list.
Replace the common power switch that fluorescent lamp is installed with the utility model, except that making it have light modulation, electricity-saving function, can adapt to outside the different illumination needs, when making fluorescent tube be in the utilization of light modulation (economize on electricity) state, owing to sealed in capacitor C, can also bring a series of advantage:
1, suitably reduced the operating current of fluorescent tube, to slowing down the aging of fluorescent tube, it is useful to prolong its useful life, and measured result is seen attached list.
2, the equiva lent impedance of fluorescent tube is raise, improved the stability of photoluminescence (the logical output of light be subjected to the influence of mains fluctuations littler) of fluorescent tube than conventional line.
3, broadening the accommodation of fluorescent tube to supply voltage, see attached list, even superelevation significantly of normal phase of supply voltage is unlikely that also fluorescent tube is caused damage; Also be difficult for when descending significantly fluorescent tube is extinguished.
4, the power factor of fluorescent tube branch road increases than conventional line.
5, make the impedance operator of circuit be capacitive (overcompensation), it is rarely that this specific character is in the electrical appliance, so can compensate a part of reactive power of other perceptual household electrical appliance such as transformer, motor by it, improve the load characteristic structure of electrical network, it is useful that the power factor that improves electrical network is reduced loss.
6, because the impedance operator of circuit is capacitive, just need not again the building-out capacitor C also (power factor is low all the better after the adjunction) in the adjunction conventional line, the disposable installation cost of fluorescent lamp is minimized.
In addition, the utility model also can be used for the power adjustments of other household electrical appliance such as incandescent lamp, electric fan, one-object-many-purposes, (A, B binding post can exchange use as regular tap in the accompanying drawing 5) easy to use, dependable performance, capacitor C also just makes the light modulation of this switch, economize on electricity effect disappear just in case puncture, on-off action still exists, unlikely scrapping.
According to the subordinate list data, just can produce the utility model product of adapted different size fluorescent tube, in addition, producer also can comprehensive selection parameters (mainly being the capacity of C), produce can adapted all size fluorescent tube the utility model product (this moment, power savings can slightly fluctuate), to improve the versatility of product, reduce the user and select supporting trouble.
Stay-supported embodiment schematic diagram of the present utility model is seen accompanying drawing 6, and D is an outer terminal among the figure, and C is a capacitor, and R is a resistance, and thick black line is an internal connecting wire.
The utility model is simple in structure, and economic and reliable need not special producing equipment and technological requirement, is example with the stay-supported, and producer only need strengthen the shell of original double control-type (SP3T) pulling switch, and C is loaded into capacitor, just can go into operation.
