Category: Light Laser LED Circuits / Fluorescent Circuits This circuit is also crossed to: Lighting Views: 5017 Rank: 0 In this circuit, one, two or three neon indicator bulbs can be made to flash in sequence at rates determined by the R and C values. In the single stage circuit, using one lamp, the capacitor charges through the resistor until the ionization potential of the neon is reached (about 70 volts) and then discharges quickly through the lamp until the voltage falls below what is needed to sustain the lamp which is approximately 45 volts. The cycle then repeats at a rate of about 3 Hz for values shown. Smaller R or C values increase frequency, larger values decrease frequency. All capacitors should be the non-polarized variety with a 100 volt or more rating. For more than 3 stages, the lamps may need to be matched for similar turn-on voltages. visit page.

Related circuits 12 Volt Fluorescent Lamp circuits Here is the schematic diagram for a 20 Watt driver. I developed this circuit in 1985, and used it to build a lamp that found much use both as camping light and as emergency light during the then-frequent power outages. The two transistors work as a push-pull oscillator. To avoid crossover... Digital DALI Ballast for 36W/T8 220V The Digital Addressable Lighting Interface (DALI), international standard prlEC929, is a communication protocol and method to interface lighting units on a 2-wire network. The DALI protocol is 16 bits and supports addressing up to 64 ballasts individually, 16 groups or broadcasting to the... A ballast that is dimmed from a (phase cut) dimmer Virtually all domestic and professional dimming systems are based on triacs. These devices will conduct once they have been fired, only while current flows in excess of the holding current of the device. These dimmers work very well with a resistive load such as an ordinary Tungsten filament... The circuit is based on IC1, which is a 555 timer IC in astable mode. It will power a 6 inch 4 Watt fluorescent tube off a 12 volt supply, consuming 300 mA. It may also be powered by a suitably rated universal AC/DC adapter. Advantages of the design are: good light, low power consumption, and...
