In a wireless communication terminal having a flashlight, the power consumption is decreased by means of enabling a transmitter to transmit during transmission periods, and disabling the transmitter outside the transmission periods. Moreover, a supply of voltage from a common power supply to a flashlight unit is disabled during the transmitting periods of the transmitter.

Wireless terminal having a flashlight

A lighting control arrangement controls the user interface lighting in a portable electronic device. An output of the lighting control arrangement selectively provides lighting intensity commands to a lighting controller. Each of the lighting intensity commands indicates one of certain basic lighting intensity levels. A level selector repeatedly changes, at a frequency that is higher than an integration frequency of a human visual system, the lighting intensity command to be provided at said output.
