Description

Relay starting switch for lamps in various kind of type

The utility model relates to a kind of illuminating lamp, particularly a kind of fluorescent lamp mixed lighting lamp relay starter of incandescent lamp ballast.

Replace the mixed lighting lamp of fluorescent lamp ballast with incandescent lamp, have that two kinds of photochromic complementations, ornamental strong, in light weight, no hum are disturbed, technology simply reaches advantages such as saving copper, iron, its light efficiency is higher than incandescent lamp, power factor is higher than the inductance ballast fluorescent lamp.Certainly, the fluorescent lamp mixed lighting of incandescent lamp ballast be realized, two kinds of lamps luminescent condition separately must be satisfied simultaneously.

The purpose of this utility model is that a kind of mixed lighting lamp relay starter will be provided, and can make fluorescent lamp under the situation of incandescent lamp ballast, and is normally luminous with white heat, realizes mixed lighting.

Task of the present utility model is finished like this:

Have the mixed lighting lamp relay starter of direct current relay J, starter S, capacitor C and diode D1 to the D3 formation of one group of transfer contact, its relay, starter and diode D1 are serially connected with between two groups of filaments of fluorescent lamp, form start-up circuit.Capacitor is connected in parallel on incandescent lamp ZP two ends, forms ballasting circuit.The end of fluorescent lamp RG is connected ballasting circuit by relay transfer contact J, and diode D3 in the normal-closed end parallel connection of transfer contact, and its Chang Kaiduan is connected to the nearly power end of start-up circuit through diode D2.When energized, the starter closure, relay gets electronic work, and the normal-closed end of its transfer contact disconnects, and makes diode D3 seal in ballasting circuit, and Chang Kaiduan connects diode D2 and makes the capacitor charging.Simultaneously, the half-wave DC through diode rectification makes the filament of fluorescent lamp preheating by the incandescent lamp current limliting.After starter disconnected voluntarily, capacitor lost discharge loop, and the voltage on it rises rapidly, and was superimposed to lamp RG two ends with supply voltage, made it starter.Relay electric-loss resets therebetween, and the Chang Kaiduan of transfer contact disconnects, and normal-closed end is with diode D3 short circuit, and fluorescent lamp, incandescent lamp transfer alternate current operation to together and normally luminous, and starter is no longer closed.

Above-mentioned mixed lighting lamp, the rated current of its incandescent lamp has determined the fluorescent lamp operating current, the operating voltage of fluorescent lamp has determined the rated voltage of incandescent lamp.Capacitor is connected in parallel in the ballasting circuit, can cooperate incandescent lamp to provide fluorescent lamp desired operating current, and can provide the enough voltage that refires to fluorescent lamp, has avoided pure electric capacity ballast that lamp tube current is impacted and scintillation again.

Therefore the mixed lighting lamp relay starter that provides of the utility model, change by the starter control relay, satisfied fluorescent lamp under the situation of incandescent lamp ballast, necessary condition with the incandescent lamp mixed lighting, and for adopting the ballast of various ways, fluorescent lamp created condition, LC Energy-saving ballast especially.

Below elaborate again in conjunction with the accompanying drawings with embodiment:

Fig. 1 is a kind of application circuit of the mixed lighting lamp relay starter that provides of the utility model.

Fig. 2 is the another kind of circuit diagram of utilization Fig. 1 circuit theory.

Fig. 3 is the energy-saving daylight lamp circuit diagram that the utility model cooperates the LC ballast to use.

Mixed lighting circuit for lamp as shown in Figure 1, energising back starter S closure, relay J gets electronic work, and diode D2, D3 and resistance R x are switched on, and diode D4 seals in incandescent lamp ZP circuit, and in parallel with resistance R x, diode D3 branch road.Half-wave DC through diode D1 rectification by Rx, the D3 current-limiting circuit in parallel with ZP, D4, makes two groups of lamp preheatings of fluorescent tube RG, and resistance R x cooperates with incandescent lamp to replenish the enough preheat curents of filament.Be serially connected in diode D5 to D7 and capacitor C2 in the start-up circuit, can provide relay stable operating voltage, resistance R P makes the fault fuse protection.When alternating current is reverse,, can only charge to capacitor C3 through diode D2 because of diode D3, D4 blocking-up.Starter closes Quan Houfu and disconnects again, and capacitor C3 loses discharge loop, and charging voltage rises rapidly, and is superimposed to fluorescent tube RG two ends with supply voltage and then makes its starter.Meanwhile relay electric-loss resets, and diode D2, D3, resistance R x all are disconnected, and diode D4 is by short circuit, and fluorescent lamp and incandescent lamp transfer Alternating Current Power Supply to simultaneously and normally luminous, and starter is no longer closed.

In the mixed lighting circuit for lamp as shown in Figure 2, the high-pressure side of transformer B is connected in the ballasting circuit, low pressure side joint tungsten halogen lamp LZ.During energising, starter S closure makes the relay adhesive, and resistance R x and diode D3 insert ballasting circuit, through transformer B, makes fluorescent lamp preheating by current-limiting resistance Rx through the half-wave DC of diode D1 rectification, and its starter process is identical with circuit shown in Figure 1.Relay electric-loss resets back resistance R x and diode by short circuit, and the electric current by transformer becomes interchange, makes that low-voltage halogen tungsten L2 is luminous to throw light on jointly with fluorescent lamp.

In LC ballast daylight lamp circuit shown in Figure 3, relay and starter are with being connected in the heater chain of fluorescent tube RG, and capacitor C2 and inductor ZL are connected into the LC ballasting circuit.Energising back starter S closure, the relay J adhesive makes the contact conversion, and alternating current is through capacitor C2 and inductance ZL current limliting, and two the reverse parallel connection branch roads of Chang Kaiduan by diode D1, starter S and diode D2, transfer contact J make fluorescent tube RG preheating.After starter disconnected, power supply propped up road direction capacitor C2 charging by D2 and makes daylight lamp glow starting, treats that relay resets, and diode D2 branch road disconnects, and fluorescent lamp is normally luminous, and starter S is no longer closed.
