Solar powered lamp with brightness control

摘要

A solar powered garden lamp (100b) is disclosed. The lamp (100b) includes a lamp assembly, a solar panel (192), a rechargeable battery (150), a sunlight-hour switch (154), an LED (146) and a control circuit. In use, a user estimates the number of hours of sunlight incident on the solar panel (192) and then indicates this using the sunlight-hour switch (154). A weather variability factor is applied to the battery charger capacity that is connected to the solar panel to help account for days of lesser light. The solar panel (192) converts solar energy into electric power to recharge the battery (150) during the day so that the battery (150) has sufficient power to light up the LED (146 at the predetermined brightness, determined by the sunlight-hour switch (154), continuously from dusk to dawn.
