Abstract
A night-light (100) having a light source (104) and control circuitry (110), which is arranged to receive a temperature input comprising a measure of temperature measured by a temperature sensor (208). The light source (104) is arranged to emit light in a first color when the temperature measured by a temperature sensor (208) is within a predetermined range and to emit light in an alternative color when the temperature measured by the temperature sensor (208) is outside the predetermined range. The night-light may be of particular use in babies' nurseries.
Claims24
A nursery night-light comprising:
- a housing;
- a light source being located within the housing;
- a frosted dome being attached to the housing, the dome configured to diffuse light generated by the light source;
- control circuitry arranged to receive a temperature input comprising a measure of temperature measured by a temperature sensor and to control the light source, the light source being arranged to emit light of a first colour when the temperature input is within a predetermined range and to emit light of at least one alternative colour when the temperature input is outside the predetermined range;
- and
- at least one secondary temperature indicator arranged to indicate whether the temperature input is within the predetermined range, the at least one secondary temperature indicator is additional to the light source,
- wherein the at least one secondary temperature indicator is located on the housing such that a viewer visualizes without looking through the dome.
The night-light according to claim lwherein the at least one secondary temperature indicator comprises a display means arranged to display a symbol.
