Description

The multi-functional dimmer of fluorescent lamp

The utility model relates to a kind of light modulating device that can change civil day light modulation brightness in the lighting field, makes the fluorescent lamp adjustable brightness and can hold concurrently and transfer incandescent lamp brightness and temperature adjustment, speed governing.

At present, the incandescent lamp dimmer is seen everywhere on the market, and the normal domestic fluorescent lamp does not also have practicable light modulating device to come out, fluorescent lamp list lamp Dan Liang, and the power power consumption is fixed, and can not need regulate by operating position and illumination.

The purpose of this utility model provides a kind of tunable arrangement of civil day light modulation brightness, and it can not only light modulation, and can also economize on electricity, and can hold concurrently and transfer incandescent lamp brightness and temperature adjustment, speed governing, to satisfy people's various different needs.

The utility model is provided with voltage multiplying rectifier starting circuit 1 in insulation crust, polarity switching 2, and electric capacity light adjusting circuit 3, external connection electrical apparatus socket 4a4b, function control switch 5 is formed structure such as accompanying drawing figure one.Circuit theory is seen accompanying drawing figure two.Capacitor C 1, C2, C3, C4, C5 (appearance value scope is 0.5 μ F-5 μ F/630V) among the figure two, diode D1, D2, D3, D4, D5, D6 (withstand voltage 630V electric current 1A) constitute the voltage multiplying rectifier starting circuit, and the electric current I flow direction and direct current (+) (-) polarity are as shown in FIG.; K1, K2, K3 and K are function control switches, and RD is a fuse; 4a and 4b are the external connection electrical apparatus sockets; C is adjustable dividing potential drop electric capacity, mainly undertakes the light modulation effect; Polarity switching is an inner double-point double-throw switch through certain electrical connection (as shown in the figure), and fluorescent tube two ends direct voltage polarity can be changed, to overcome the electrophoretic effect (being fluorescent tube one end obfuscation phenomenon) that occurs in the burning-point process; Current limliting starter resistance R 1 and R2 are 25 Europe/4 watt, and R3 is 150 kilo-ohms/1 watt.Getting rid of external connection electrical apparatus socket 4a, 4b and K switch 3, promptly is fluorescent lamp dimmer main circuit.In the main circuit, the dividing potential drop capacitor C that the appearance value is adjustable, after being linked in sequence by K switch 2 and voltage multiplying rectifier starting circuit and polarity switching, be connected on lamp tube ends respectively by R1, R2 again, direct voltage (+) (-) polarity is connected on respectively on two cuttves of polarity switching double-point double-throw switch.After control switch K1, K2 close, exchange 220 volts of supply voltages and become direct current by dividing potential drop capacitor C and voltage doubling rectifing circuit, be added in lamp tube ends by polarity switching and R1, R2 again, daylight lamp glow starting is lighted.Change the capability value of adjustable dividing potential drop electric capacity, promptly changed fluorescent tube both end voltage and line current, and then changed fluorescent lamp brightness, reached the purpose of light modulation.

The circuit that appliance socket 4a4b and K switch 3 constitute is the circuit of setting up outside the homophony optical circuit, has increased the function of fluorescent lamp dimmer.After control switch K2 disconnected, outer meeting resistance electrical equipment or capacitive character electrical equipment among the socket 4a impelled line current to change and also can reach the light modulation purpose, and make the electrical equipment that seals in bring into play original part effect.And socket 4b is connected between the dividing potential drop capacitor C and the power supply other end by control switch K3, can external incandescent lamp or electrical equipment such as electric mattress or electric fan, and the capacity that changes the dividing potential drop capacitor C just can carry out light modulation or temperature adjustment or speed governing to the electrical equipment on the 4b socket.

In accompanying drawing two main circuits, the dividing potential drop capacitor C can be separated separately and constitute independently dimmer switch, is used for regulating the inductance ballast formula or the electronic ballast formula fluorescent lamp of former various power, and the main circuit after C isolates can directly be put fluorescent lamp, but can not light modulation.

The employing of above technical scheme has improved former civil day light modulation list lamp Dan Liang, and power, power consumption are fixed and the weak point that can't change, and can satisfy people to the various different demands of illumination and saved electric energy, benefits the nation and the people.

In the accompanying drawing, figure one is the structure composition diagram, the 1st, and the voltage multiplying rectifier starting circuit, the 2nd, polarity switching, the 3rd, electric capacity light adjusting circuit, 4a4b are the external connection electrical apparatus sockets, the 5th, function control switch.Figure two is electrical schematic diagram (each mark is aforementioned among the figure mentions).Figure three is the 3rd enforcement illustrations, and K, K1 are control switchs among the figure, and C is the dividing potential drop dimming capacitors, and L is the fluorescent lamp Inductive ballast, and S jumps bubble, and RD is a fuse.

Now reaching specific embodiment in conjunction with the accompanying drawings further specifies:

Example one: have high light, middle light, the low light level and stop shelves 40W fluorescent lamp dimmer, referring now to accompanying drawing two explanations.Close a switch in proper order during the high light shelves behind K (making the capacitor C short circuit), K1 and the K2, directly put fluorescent lamp, and overcome dark end electrophoretic effect, lamp power 40W with polarity switching; Middle light shelves (disconnecting K) dividing potential drop electric capacity value 10 μ F, lamp power 25W, power saving 35%; Low light level shelves dividing potential drop electric capacity value is 4 μ F, lamp power 14W, power saving 65%.The adjustable extent of dividing potential drop capacitor C is between 0.5 μ F-15 μ F.

Example two: with reference to accompanying drawing two explanations.In only needing night in winter during optical illumination, K (short circuit C) and K1 can close a switch, in the 4a socket, insert Electric heat matress for double bed, can make 40W inductance ballast fluorescent lamp power be adjusted to 25W, electric blanket sends about 14W power heating bed by usefulness simultaneously, makes the fluorescent lamp dimmer play two kinds of effects of illuminating and heating.

Example three: three explanations in conjunction with the accompanying drawings.Utilize the independent light modulation effect of dividing potential drop electric capacity, to 40W inductance ballast fluorescent lamp carry out by force, in, the light modulation of low light level third gear, among this embodiment, the K that closes (short circuit C) promptly is former inductance ballast 40W, is the high light shelves; Disconnecting K is middle light shelves, dividing potential drop capacitor C value 2.2 μ F, lamp power 25W; Low light level shelves dividing potential drop capacitor C value 1 μ F, lamp power 10W.
