The growing awareness of environment concerns means that energy saving devices are gaining considerable prominence. In the past decade one such effective means is the LED. LED lighting has come to become the most significant aspect of any house or commercial establishment. LEDs are used today in a variety of forms like LED tubes for lighting up the workspaces and in the house for kitchen and working desks, LED flat panels for lighting up certain areas of the house, they being flush mounted are preferred as they do not alter any architectural design of the house.
The last few years have resulted in further focus on the environment aspect of energy savings and this has resulted in the development of dimmers for further optimizing electricity usage. There are some significant advantages of using dimmers and this subsequently resulted in their popularity among the consumers.
Advantages of Dimmers:
– Convenience and improving ambiance: Homes are becoming increasingly automated. Lights as part of the automated system can therefore be dimmed depending on the time of the day to ensure optimum light maintenance, some are even equipped with intelligent systems which switch off the lights in the absence of any person. They also enable the user to give a nice feel to a house or office using the lighting systems, thus improving ambiance.
– Energy saving: As the intensity of light can be changes depending upon the need of illumination required, it helps by optimizing the use of electricity and in the process it also reduces electricity bills.
How to dim an LED?
There are two techniques used when dimming LEDs, PWM and Analog. Both techniques come with their own advantages and disadvantages.
PWM dimming mainly involves switching the light bulb on and off at an extremely high rate, the advantage of this process is because the quantum of current passing through the LED remains the same, the color of light does not change.
Analog dimming meanwhile involves sending a variable current, the advantage here primarily being simpler logic circuits,
How to use dimmers in Induction lights?
Induction lights have recently reemerged as a strong contender in the lighting industry especially the outdoor lighting realm. They are typically used in gas station lighting, parking garage lighting and street lighting.
Technology also advanced in induction lighting, which involves the use of dimmers. Most of the times inductive lightings are fitted with a dual control switch or some sort of a bi-level dimming feature. Many of them are also fitted to smart and intelligent automated systems which regulate the induction lights for example the induction lights which are fitted in the parking garage now come with a dual switch which is connected to an infra-red system. The system normally maintains low illumination, however if it detects any human through the infra-red then it automatically switches to high illumination.
