Description

Energy-efficient electric daylight lamp

The utility model relates to a kind of light fixture, does not especially have the electric daylight lamp of ballast and starter.

The present fluorescent lamp that uses, major part is also all continued to use the structure of old-fashioned ballast and starter.Ballast is very heavy, the cost of manufacture height, and the power factor of reduction electrical network is installed inconvenience, and safety factor is low, easily produces and rings, and has a lot of drawbacks.Thereby existing a lot of with the scheme of electronic circuit replacement ballast and starter, but the complex structure that has, the poor reliability that has, the really new solution that can effectively implement and few.

The purpose of this utility model provides a kind of simple in structure, the electric daylight lamp that cost is low, energy-efficient.

The utility model is made up of fluorescent tube and electronic circuit, and it adopts electronic component to replace ballast and starter, and electronic component comprises two diode D ₁, D ₂, two capacitor C ₁, C ₂, a resistor R.Civil power 220V phase line of power is connected to diode D by K switch ₁Anode, D ₁Negative electrode connect two pins of fluorescent tube L one end, and by capacitor C ₁, C ₂Be connected to diode D ₂Anode, D ₂Anode connect two pins of the fluorescent tube L other end by resistance R; D ₂Negative electrode receive D ₁Anode, zero-power line connects C ₁, C ₂Between contact.

In the circuit, diode D ₁, D ₂With capacitor C ₁, C ₂Formed voltage doubling rectifing circuit.Behind the power connection, the fluorescent lamp two ends can produce high pressure, and fluorescent tube is lighted rapidly.

The utility model is simple in structure, adopts element few, and cost is low, and volume is little, and is easy for installation; Save ballast, helped improving power factor of electric network, like this can power saving, can reduce working temperature again; Because circuit has saved starter, fluorescent lamp no longer includes scintillation, has prolonged the useful life of fluorescent tube; In addition, two pin short circuits of fluorescent tube one end, no current is by filament, thereby fluorescent tube is not fragile, even the useless pipe of fracture of wire is arranged, as long as air tight, still can use; Electronic component can be concentrated and be contained in the small and exquisite lamp socket, makes light fixture aesthetic in appearance.

Accompanying drawing 1 is circuit theory diagrams of the present utility model.

The component parameters of execution mode is as follows:

Fluorescent tube L:220V/40W;

Rectifier diode D ₁, D ₂: more than the withstand voltage 620V;

Capacitor C ₁, C ₂: metallized-paper capacitor 3 μ F/620V;

Resistor R: 200 Ω electricity group line.
