Abstract
The utility model discloses a starting switch for lamplight, which can start a fluorescent lamp without any starter or ballast. The voltage of the starting switch for lamplight is lowered by a capacitor 1. The voltage at both ends of a load is 300V or so through a voltage doubling rectifying power supply composed of capacitors 2, 3, and rectifying diodes 4, 5. Therefore, the voltage at both ends of the load is less than 600V which is an index in the prior art, the service life of a lamp filament is prolonged, and simultaneously the cost is reduced.
Description
The utility model relates to a kind of fluorescent lamp Starting switch for lamplight.
At present, people's fluorescent lamp used in everyday all is that starting time is long by ballast and starter starter, and the instantaneous power consumption of starter is big.
The purpose of this utility model provides a kind of Starting switch for lamplight that does not need ballast and starter just can make daylight lamp glow starting.
The purpose of this utility model be achieved in that it by electric capacity 1, electric capacity 2, electric capacity 3, diode 4, diode 5, resistance 6, and housing 10 form.Wherein: one of electric capacity 1 terminates on the input, the other end is connected with an end of electric capacity 2 and electric capacity 3, the other end of electric capacity 2 is connected with the anode of diode 4, the other end of electric capacity 3 is connected with the negative electrode of diode 5, they are placed in the housing 10, draw input termination 220V power supply from the negative electrode of electric capacity 1 and diode 4 and the anode of diode 5 respectively, draw output 8 from the anode of diode 4, the negative electrode of diode is drawn output 9.
Fig. 1 is a structural representation of the present utility model.
Also the utility model will be further described to provide embodiment of the present utility model below in conjunction with accompanying drawing.
As shown in Figure 1, switch opens with lamp, feed 220V voltage, reduce voltage through electric capacity 1, behind the voltage multiplying rectifier power supply of electric capacity 2,3 and rectifier diode 4,5 compositions, the voltage between the output 8,9 is reached about 300V, thereby reduced many again than the 600V of prior art, lamp tube service life is prolonged, reduce device cost.The voltage multiplying rectifier power supply that above-mentioned parts are formed places in the housing 10, draws output 8,9 connecting resistances 6 and fluorescent lamp 7.The span of each parts is according to the different corresponding selection of fluorescent lamp (being load) 7 power, as: when fluorescent lamp 7 was 60W, electric capacity 1 was 14～20 μ F, and electric capacity 2,3 is 7～10 μ F, withstand voltage 250～630V, and resistance 6 is 60W; When fluorescent lamp 7 was 40W, electric capacity 1 was 9.5～12 μ F, and electric capacity 2,3 is 4.75～6 μ F, the electric capacity of withstand voltage 250～630V, and resistance 6 is 30～60W; When fluorescent lamp 7 was 20W, electric capacity 1 was 4.4～6 μ F, and electric capacity 2,3 is 2.2～3 μ F, withstand voltage 250～630V, and resistance 6 is 20～30W; When fluorescent lamp 7 was 15W, electric capacity 1 was 4～4.75 μ F, and electric capacity 2,3 is 2～2.2 μ F, and withstand voltage 250～630V, the power of resistance 6 are 10～20W; Diode 4,5 is IN4007, withstand voltage 1000V, 1A.
The utility model is simple in structure, and volume is little, and is in light weight, noiseless, and power saving, and cost is low, and starter is fast.
Claims (2)
1, a kind of Starting switch for lamplight, it is characterized in that it is by electric capacity 1, electric capacity 2, electric capacity 3, diode 4, diode 5, resistance 6, and housing 10 is formed, wherein: one of electric capacity 1 terminates on the input, the other end is connected with an end of electric capacity 2 and electric capacity 3, the other end of electric capacity 2 is connected with the anode of diode 4, the other end of electric capacity 3 is connected with the negative electrode of diode 5, they are placed in the housing 10, draw input termination 220V power supply from the negative electrode of electric capacity 1 and diode 4 and the anode of diode 5 respectively, draw output 8 from the anode of diode 4, the negative electrode of diode is drawn output 9.
