Abstract

A lamp with a housing; a battery mounted within the housing; an illumination LED or array thereof mounted on the housing; a status display LED array mounted on the housing; an inertial sensor for sensing change of position and/or orientation of the housing; circuitry adapted to control the lamp between a quiescent state when no LED is ON, an active state when the status display LED array is ON and an illumination state when at least one illumination LED is ON and to: switch from the quiescent state to the active state on detection via the inertial sensor of a position/orientation user action of a first type alone, switching ON one or more status LED and to switch from the active state to the illumination state on detection via the inertial sensor of a position/orientation user action of a second type alone, switching ON one or more illumination LED.

Dependent claims

A lamp comprising:

a housing;
a battery mounted within the housing;
an illumination LED or array thereof mounted on the housing;
a status display LED array mounted on the housing;
an inertial sensor for sensing change of position and/or orientation of the housing;
circuitry that controls the lamp between
a quiescent state when no LED is ON,
an active state when the status display LED array is ON and
an illumination state when at least one illumination LED is ON:
wherein the circuitry switches from the quiescent state to the active state to turn the status display LED array ON upon detection of only the inertial sensor detecting a position/orientation user action of a first type;
and
wherein the circuitry switches from the active state to the illumination state on detection of only the inertial sensor detecting a position/orientation user action of a second type, switching ON one or more illumination LED, wherein the status display LED array includes a first array of LEDs to indicate battery status and a second array of LEDs to indicate illumination brightness.
