Abstract

The utility model discloses a light bulb lighting and electricity-saving device for DC low-voltage (50v) bulb. The utility model is composed of an astable circuit whose duty ratio is adjustable and a contactless switch circuit which is divide into three grades according to electric parameter of different light bulbs of lighting apparatuses. The electricity can be saved by 40% under the condition that the light stability and brightness of the lighting apparatus light emitting source (light bulb) are not changed with the standard of human eye observation, and namely, the electricity saving time can be saved by 24 seconds if the light bulb is ignited for one minute. The utility model has the advantages of low cost, small size, light weight, damp prevention, water prevention, explosion prevention, fire prevention and no fear of vibration, and is suitable for the lighting and electricity-saving need of people.

Description

Power-saving means for dc low-voltage (50V) bulb

The utility model relates to a kind of illumination power-saving device, in particular for dc low-voltage (≤50V) power supply bulb be the battery saving arrangement of light emitting source.

At present, known dc low-voltage (≤3V) torch for illumination battery saving arrangement.Bulb works in the state of flashing 90 times/minute, and the control impuls conduction ratio is 3:1, but power saving nearly 1/4.But bulb works in blink states, and having lost throws light on needs the main purpose of stabilized illumination.

The purpose of this utility model provides a kind of under the situation of the light stability that does not change ligthing paraphernalia light emitting source one bulb, brightness, and economize on electricity 40% was promptly lighted bulb one minute, 24 seconds the time of can economizing on electricity, dc low-voltage (≤50V) bulb illumination battery saving arrangement.

The purpose of this utility model is achieved in that the power save circuit piece that installs a whole embedding in ligthing paraphernalia additional; And the mains switch work of ligthing paraphernalia suitably changed, change double-throw into as singly throwing mains switch, wherein spend the circuit that still connects former luminaire tool extravagantly, another is thrown and connects the battery saving arrangement circuit; (do the global design that promptly keeps former luminaire tool like this, bring convenience for again this device of installation, ligthing paraphernalia reliability behind this device also improve to be installed) when this device circuit is connected, (former luminaire tool power supply disconnects simultaneously) exports the pulse with critical flicker frequency, optimum taking air ratio by the astable circuit that mixes up duty ratio, triggers, controls the next stage noncontacting switch; Make light emitting source-bulb synchronous light-emitting of being serially connected in the noncontacting switch, extinguish, luminous ... reach the purpose of economize on electricity.

The utility model is that 46Hz～54Hz duty ratio is the adjustable astable circuit (I) of 3:1～11:9 by " a 555 " time-base integrated circuit or by the output frequency of oscillation that transistor is formed, and divides the non-contact switch circuit (II) of three class according to the bulb electric parameter of different ligthing paraphernalias; First grade is the noncontacting switch (II-a) of the triode formation that common emitter is oppositely saturated and voltage VCES value is little, second grade is the noncontacting switch that constitutes of once-through type solid-state relay DC-SSR (II-b), third gear is the noncontacting switch that constitutes of the little one-way SCR of an on-state average voltage drop VF value (II-c), and with reference to behind the volume of different ligthing paraphernalia mains switches, the electric parameter, the commutator of replacing (III); Ligthing paraphernalia-low-voltage DC supply power supply (IV) and light emitting source-bulb (V) are formed.

The human eye critical flicker frequency of the utility model basis is to be 0.03 second～0.2 second the effective visible sensation time of persisting of 46Hz-47Hz and human eye, go out " the no stable state of EDM Generator of Adjustable Duty Ratio " each component values of circuit by frequency and computation of Period, overlap circuit diagram shown in Figure 2, the numerical value that draws by experiment conforms to measured value.(seeing Table)

Light emitting source-bulb switching time ratio	3：2
		But light emitting source-bulb energising power saving second	24
This device economize on electricity percentage	40％

Compared with the prior art the utility model has the advantages that: can under the situation that does not change the light stability of bulb, brightness, economize on electricity 40%; And cost is low, volume is little, in light weight, moistureproof, waterproof, explosion-proof, prevent fires, be not afraid of vibration, install simplely, be fit to the needs of people's illuminating energy-saving.

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

Fig. 1 is the utility model electricity functional-block diagram.

Fig. 2 is the utility model circuit diagram.

Embodiment 1: this device double-throw mains switch is pulled when connecting energy-saving circuit, and the circuit of former luminaire tool mains switch disconnects simultaneously; Matrix is started working when " 555 "; Because diode D ₁, D ₂Matrix charge circuit R during with " 555 " ₁, R ₂The first half and discharge loop resistance R ₅, R ₂The latter half is separated, so regulator potentiometer R ₂The time, charging resistor R ₁+ R ₂The first half and discharge resistance R ₅+ R ₂The latter half changes, and promptly duty of ratio changes; Because charge and discharge resistance summation is constant, 50Hz is constant frequently so matrix output is shaken when " 555 "; 3. pin, resistance R of matrix when " 555 " ₃Be transferred to II-a noncontacting switch; At the high level frequently that shakes, when the direct impulse of square wave arrived, II-a non-contact switch circuit made the ligthing paraphernalia light emitting source-bulb of serial connection get electroluminescence by saturated by being turned to; During low level, II-a is ended by saturated being turned to, bulb outage stopping luminous lighting.

Embodiment 2, and operation principle is with embodiment 1, and difference is that noncontacting switch has improved a class on the electric parameter that bears ligthing paraphernalia light emitting source-bulb.（Ⅱ－b）

Embodiment 3, and operation principle is with embodiment 1, difference be that (II-c) improves a class to noncontacting switch once more on the electric parameter that bears ligthing paraphernalia light emitting source-bulb.
