Mention ‘touch control’ or ‘touch sensors’ today and mostly all will think about a device similar to touch screens. Touch control devices are wide in practice like in grocery stores, tablet computers, smart phones, cash machines at banks, security devices at home, etc. now even touch sensor lamps are also been widely used in market.
From many years switches that must be pushed or flipped to break and make mechanical connects are not choose over switches that are sensitive to human touch. The main advantage of these touch sensitive lamp or switch is that they do not get gummed by or damaged by touch that brings moisture and dirt to the switch. Over a period of time different human body property have been used to flip touch sensitive lamps
There are many advantages to touch control lamps but before going there let us consider it in boarder sense to acknowledge the segmentation of the markets into which they come under and the multitude of applications. These touch sensor lamp and other technologies are not new and simple search on internet will give you thousands of similar results. Most of these are used in vanity products (makeup mirror illumination), table, desk and bedside lamps and mood lighting systems but it is interesting that they are effectively reducing the market of standard lamps.
Reason to this is not single line answer. These are used for their –
- Cool technology
- Practical nature.
Technology has added more features than just sensor touch. 3 to 4 level of light diming mechanism is added to the touch sensor lamps making more apt for consumer usage.
Mechanical wear of moving parts is not suffered by these capacitive touch sensors adding a natural advantage in its bag and so are more reliable. The electronics as placed behind closed or sealed surface environment contaminations like moist and dust are effectively avoided. Thus increasing the shelf life of the device.
When evaluating lighting controls power consumption may not be a designer’s first priority as most lighting systems powered by mains electricity. Parameters such as current and the availability and operating voltage of any low power modes are important selection criteria.
