LED Dimmer Switch Enables More Possibilities for LED Lighting
When it comes to LED lighting, the most important features are high energy efficiency, luminous flux and low heat generation. Actually more possibilities of LEDs can be activated while working with a LED dimmer switch.
A LED dimmer switch enables users to create the right moods for their different environments by adjusting the brightness of LED lamps and setting dynamic changing patterns. Many people have no idea that how to choose a right dimmer switch for their LEDs since there are many types of LED dimmer switch available in the market. Actually it is not that difficult as they think, figure out the following issues prior to purchasing a dimmer switch for your LED lamps, you will definitely get what you want.
LED lamps in the market are available with different input types: AC and DC. First you have to confirm the input type of your LED lamps. Generally the lights with high power LEDs as light source are designed with AC high voltage input, for instance LED bulbs and high power LED downlights. The lights with SMD LEDs as light source are designed with DC low voltage input, for instance LED strip lights and LED panel lights. These specifications are clearly printed on the package or user manual of the lamps.
Of course the basic requirement is that your LEDs shall be dimmable. Please be noted that not all of them are dimmable and some are non-dimmable. It is impossible to dim non-dimmable LEDs, what you get will be flickering or burning out if you do so.
Once above issues are clear, the next step is to calculate the total load of LED lamps you would like to control. And the maximum load shall not exceed the LED dimmer switch’s maximum output power, otherwise the lamps can not work well.
There are various types of dimmer switch available in the market, Triac (phase cut) and PWM are the most popular ones. Generally Triac is for only for AC LEDs, and PWM can be used for both AC and DC input LEDs depending on the dimmer design. What you need to do is to choose corresponding ones according to the input type of your lights. AC LEDs shall work with an AC output dimmer, DC LEDs shall work with an DC output dimmer.
Control unit is a signal sender that sends control signal to the dimmer, there are many types of control unit available in the market including traditional push switch, analog signal (0/1-10V), digital signal (DMX, DALI) and wireless signal (RF, IR) etc. You can choose according to your preference, and you have to make sure that the dimmer shall designed with the corresponding control interface. Once figure out all these 5 issues, you will choose the correct dimmer switch for your LEDs.
