Abstract
The utility model belongs to products of fluorescent lamp domestic electronic class. The utility model adopts high-frequency oscillation principle to generate high pressure to start the dimming igniting device for lumination of fluorescent lamps. The dimming igniting device alters the current flow amount flowing through a lamp by increasing light regulating lines and regulating coil inductance to achieve the purpose of light regulation. Products produced with the technique has the advantages of simple structure, low cost, favorable performance of starting with low pressure, and obvious light regulation.
Description
The utility model relates to a kind of fluorescent lamp light modulation and lights device, belongs to the domestic electronic series products.
The more traditional Inductive ballast of electronic ballast for fluorescent lamp has many advantages at aspects such as economize on electricity, starters, but because of its can not light modulation, complex structure and cost Gao Erwei be widely adopted (seeing Chinese patent 93237140.X, Chinese patent 2207225.6 etc.).
The purpose of this utility model provides a kind of simple in structure, and cost is low, and device is lighted in the fluorescent lamp light modulation of tunable optical.
The utility model circuit theory as shown in Figure 1.It comprises current rectifying and wave filtering circuit, oscillation inverter circuit, light adjusting circuit, starter rectification circuit.The energized switch, electronics is lighted device and is started working, and obtains direct voltage by current rectifying and wave filtering circuit, and the oscillation inverter circuit converts this direct voltage to high frequency voltage, and this voltage makes the normal starter of fluorescent lamp behind the circuit of starter ballast.At this moment, a light adjusting circuit K, L connect at oscillation inverter output choke place
2, when K was closed, fluorescent lamp sent normal luminosity; K disconnects dimmer L
2Start working, this moment, the light of lamp weakened.Above-mentioned light modulation circuit also can be designed to dimmer L
2With after switch is connected again with choking-winding L
1In parallel (as shown in Figure 2), thus reach the purpose of light modulation.
Be described further below in conjunction with 40w fluorescent lamp example: the energized switch, electric ballast is started working, form the high direct voltage of about 300V through current rectifying and wave filtering circuit, high-frequency oscillating circuits converts this direct voltage to the high frequency voltage of the about 30KHz of frequency, this voltage is behind starter, just can make the fluorescent lamp operate as normal, when the K in the light adjusting circuit was in closure state, this moment, fluorescent lamp sent the brightness that luminous flux is equivalent to 40W; K disconnects, dimmer L
2Start working, this moment, the light of lamp weakened to being equivalent to the luminous flux of 20W fluorescent lamp, thereby reached the purpose of light modulation.
The utility model is compared with prior art products has following characteristics: simple in structure, cost is low, and the low-voltage starter performance is good, and light modulation is obvious.
Claims (2)
1. the utility model is a kind ofly to produce high-frequency and high-voltage with the oscillation inverter principle and light device to start the luminous light modulation of fluorescent lamp, is characterised in that ballast higher-order of oscillation output choke place connect a light adjusting circuit K, L
2
2. be characterised in that dimmer L according to the bright device of claims 1 described fluorescent lamp light modulation electricity
2With after switch is connected again with choking-winding L
1In parallel.
