A Patent
1 A shower head in which LEDs give a feedback about the water temperature, comprising:
• An alternator which provides the power,
• A mini turbine which is coupled to the alternator,
• A plurality of LEDs of different colors,
• A temperature sensor which activates the LEDs,
• A control module which controls the LEDs,
• A housing, for being hand held in a user’s hand.
2 The shower head of claim 1, in which the alternator used for the control of watering systems in field crops, is further used: as a component of the shower head.
3 The shower head of claim 1, wherein: the turbine is located along the water passage.
4 The shower head of claim 1, wherein: according to the water temperature detected by the temperature sensor, the selection is made to one set of LEDs rather than to another set of LEDs.
5 The temperature sensor of claim 4, wherein: two sets of LEDs can be activated at the same time to create a third color.
6 The temperature sensor of claim 4, wherein: some LEDs are red and the control module activates the red LEDs when the water temperature is too hot, and constitutes a danger to persons, or it activates other colors when the water temperature is warm, and constitutes no danger.
7 The shower head of claim 1, wherein: an ON/OFF switch may be built into the device.
8 The shower head of claim 1, wherein: three styles are available, single, sensitive or rainbow LED color.
9 The shower head of claim 1, wherein: the cover of the shower head is removable.
