Philips TW6 Blacklight Ultraviolet Lamp
|
|
|
 |
The TW6 is a cold-cathode lamp operating directly from the 240V mains electricity supply, and apart from the outer bulb its construction is the same as the clear-glass TUV6 variant. It contains a resistance in the base to limit the current between the pair of cup-shaped electrodes. The lower electrode is connected directly to one terminal, the upper is connected to the other and its supply wire is sleeved in a glass tube painted with colloidal graphite. The electrically conductive graphite layer is connected via a high resistance to the lower electrode, and it forms an auxiliary starting electrode in just the same was as high pressure mercury lamps. The gas-filling also contains neon for easy ignition.
