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 colour when the temperature measured by a temperature sensor (208) is within a predetermined range and to emit light in an alternative colour 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.

Claims

1. A night-light comprising.

a light source;

and

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.

2. The night-light according to claim 1, further comprising a temperature sensor arranged to provide the temperature input and arranged to affix to the exterior of the night-light.

3. The night-light according to claim 1, wherein the color of the emitted light has an intrinsic meaning to an observer.

4. The night-light according to claim 3, wherein the intrinsic meaning is associated with one of hot or cold.

5. The night-light according to claim 1, further comprising at least one secondary temperature indicator arranged to indicate whether the temperature input is within the predetermined range.

6. The night-light according to claim 5, wherein the at least one secondary temperature indicator comprises one or more of the following:

a display means arranged to display a symbol, a colour, a light, a coloured light, textual instructions, temperature information;

an alarm means.

7. The night-light according to claim 5, wherein the secondary temperature indicator means has an intrinsic meaning to an observer.

8. The night-light according to claim 1, wherein the light source is arranged to emit light of at least three colours, a first colour when the temperature input is within the predetermined range, a second colour when the temperature input is below that range and a third colour when the temperature input is above that range.

9. The night-light according to claim 8, wherein the predetermined range is between roughly 16°

C. and roughly 20°

C.

10. The night-light according to claim 1, wherein the light source is arranged to emit light of four colours, a first colour when the temperature input is within the predetermined range, a second colour to indicate that the temperature input is below the predetermined range, a third colour when the temperature input is above that range, but not substantially so, and a fourth colour to indicate that the temperature input dangerous exceeds the predetermined range.

11. The night-light according to claim 10, wherein the third colour is used when the temperature input is above 20°

C.

12. The night-light according to claim 11, wherein the fourth colour is used when the temperature input is above 24°

C.

13. The night-light according to claim 1, further comprising an instruction set, linking the colour of the light to a recommended action.

14. The night-light according to claim 13, wherein the recommended actions relate to the provision of sleepwear.

15. The night-light according to claim 13, wherein the recommended actions include one or more of the following:

cool room, heat room, use light sleepwear, use moderate sleepwear, use heavy sleepwear, use an alternative room.

17. The night-light according to claim 26, wherein the kit further comprises a power supply means arranged to supply power to the night-light, the power supply means comprising the temperature sensor.

18. The night-light according to claim 17, wherein the kit further comprises a set of instructions providing details of the action recommended given the temperature of a room as indicated by the colour of the light.

19. The night-light according to claim 18, wherein the set of instructions provides a sleepwear guide which can be used by a carer to select sleepwear for a baby with an appropriate level of thermal resistance.

20. The night-light according to claim 19, wherein the set of instructions defines the correct level of sleepwear with reference to the Tog value.

21. The night-light according to claim 18, wherein the set of instructions comprises information printed on one of the night light or in an instruction manual.

22. The night-light according to claim 21, wherein the kit further comprises sleepwear of known thermal resistance.

23. The night-light according to claim 26, wherein the set of instructions further comprises information on how to site the night-light.

26. The night-light according to claim 1, further comprising a kit.
