Lamp unit for use in or with an umbrella

摘要

An umbrella is provided with a fluorescent lamp unit as part of or adjacent to (Fig 13) the shaft between the uppermost position of the slider and the canopy. The lamp may include a cylindrical lens 38 containing a U-shaped discharge tube 41, and means for receiving a low voltage supply which is stepped up by an inbuilt transformer or inverter unit 43. The lamp unit is sealed by caps 42,44 having threaded sockets 50,56 which receive threaded studs (48,54) formed on the shaft. The power supply may be a rechargeable battery in the umbrella base with wiring inside the shaft (Fig 1), or an external supply may be wired directly to the lamp (Fig 9).
