Description

Electronic starter for fluorescent lamp

The utility model relates to a kind of starter.

Existing starter starting time is longer, and lack and job insecurity useful life.

The purpose of this utility model provides a kind of electronic starter for fluorescent lamp, and it has advantages such as starting time weak point, reliable operation, life-span length.

The utility model is made up of step-down rectifying circuit, starter control circuit and executive circuit; Step-down rectifying circuit is by R ₁C ₁Step-down, D ₁～D ₄Rectification is finished, and power supply is by R ₁C ₁Input, voltage step-down is after D ₁～D ₄Full-wave rectification output; The starter control circuit is by current-limiting resistance R ₂, R ₃, relay DZ ₁With delayer R ₄, C ₂Form relay DZ ₁Be connected to R ₃One end, DZ ₁Normally-closed contact be connected to R ₄, C ₂Between; Executive circuit is by triode BG, relay DZ ₂Finish, triode BG base stage is connected to R ₄, C ₂Between, collector electrode meets DZ ₂, DZ ₂Normally-closed contact be voltage output end.Described R ₁C ₁Reduction voltage circuit can be with being with tapped Inductive ballast to replace.

Now in conjunction with the accompanying drawings the utility model is further described:

Accompanying drawing 1 is the utility model electrical schematic diagram.

Accompanying drawing 2 is another electrical schematic diagrams of the utility model.

Circuit diagram when accompanying drawing 3 is the utility model practice

As shown in drawings, voltage is through power input 1-2 to R ₁, C ₁Step-down, D ₁～D ₄Full-wave rectification provides starter work required voltage and current.The starter control circuit is by current-limiting resistance R ₂, R ₃With delayer R ₄, C ₂Finish relay DZ ₁Control delayer R ₄, C ₂Reset.Executive circuit is by BG, DZ ₂Finish, the starter control circuit is controlled BG from by the end of conducting between time delay, relay DZ ₂Change operating state from being failure to actuate into,, make the required high voltage of daylight lamp glow starting by the Inductive ballast generation to disconnect the heating circuit of filament of fluorescent lamp.

As shown in Figure 2, above-mentioned R ₁, C ₁Reduction voltage circuit can be with being with tapped Inductive ballast to replace.

As shown in Figure 3,1 is fluorescent tube, and 2 is the utility model, and C is a building-out capacitor, and L is an Inductive ballast.

Work as power connection, the filament of fluorescent lamp heating, voltage is through R ₁, C ₁Step-down, D ₁～D ₄Full-wave rectification; Because relay DZ ₁Effect, C ₂Pass through R ₄Charging, C ₂Terminal voltage raises, and causes triode BG conducting, DZ ₂Transfer operating state to, cause the filament heating circuit to disconnect, at this moment lamp tube ends moment is added with high voltage, tube starting.

The actual use of the present utility model, have starting time weak point, long service life, The advantages such as stable working state.
