Dimmer switches

A dim light emits fewer photons than does a bright light. So a dimmer switch is merely a device for varying the flux of photons emitted by a light bulb. The energy per photon is not significantly altered in this way. 

In practice, the dimmer switch incorporates a small variable resistor into the switch box, which allows differing amounts of voltage to be tapped off. ... 

Deviating from the historical development, we will illustrate these effects by a modification of the double-slit experiment. Let us equip the laser source with a dimmer switch capable of reducing the light intensity by several orders of magnitude, as shown in Fig. 2.4. With each successive filter the diffraction pattern... 

Resistors are used to regulate volume on a television or radio or through a dimmer switch for lights. 

This paper involves the Kansei evaluation of eight light dimmer switches by estabhshing which designs provoke specific emotions and ultimately which are the most pleasing to the potential user. The study also investigates if the level of satisfaction differs between genders and whether product opinion differs between coimtries. 

The adjective antonym pairs in this study were boring fun looks easy difficnlt to use looks robust fragile would look nice or terrible in my home modem traditional attractive ugly looks cheap expensive high low quahty decorative not decorative looks rehable umeliable. In the electronic version of the qnestionnaire the hst of words/terms was randomly ordered for each product to avoid bias during completion. Each respondent was asked to rate each pah of antonyms for each product on a 10-point semantic differential scale, with the opposites anchored at each end. The respondents were also asked if they would buy the dimmer switch if it was to be used on a standard (floor) lamp. Demographic... 

The location of all wall switches should not exceed 48 in above the floor. A dimmer switch with a lever handle can control the proper amount of lighting for the main kitchen light fixture and should be placed by the main door on a wall. Additional simple on/off switches can be located by other entrances. 

There is an increased use of electronic devices in electrical installation work for example, in dimmer switches and ignitor circuits of discharge lamps. These devices should be temporarily disconnected so that they are not damaged by the test voltage of, for example, the insulation resistance test (IET Regulation 612.3). 

However, enei -efficient lamps are expensive to purchase and they do take a few minutes to attain full brilliance after switching on. They cannot always be controlled by a dimmer switch and are imsuitable for incorporating in an automatic presence detector because they are usually not switched on long enough to be worthwhile, but energy-efficient lamps are excellent for outside security lighting which is left on for several hours each night.

Lighting should be bright with spotlights over the stoyes, sink and worktops. Dimmer switches are required. Fluorescent strip lighting should be used as the general lighting.
