How to choose power supply for your led light??
Whether you are building your own LED fixture, fixing and retrofitting existing fixtures, or purchasing new LED lights, you will need to find the correct power source for your LEDs. You will either need a constant current LED driver or a constant voltage power supply (or a combination of both) in order to make your LEDs work properly. There are many different factors to consider when choosing a power supply for LED lighting. Firstly, make sure if your led light is constant voltage light or constant current model. Now i want talk about constant voltage power supply. A constant voltage power supply can be used to power LED lights that have resistors or constant current drivers already within the system. These types of products will typically call for a constant DC voltage. If you are powering from a battery or happen to have a constant DC voltage that is adequate for your lights, then consider yourself lucky. Nine times out of ten this will not be the case and you will need a power supply to convert your power to a safe DC voltage for your lights. For example, LED flex strips have on-board current limiting resistors. If you wanted to install this in your car, you wouldn’t need any power supply. Cars batteries give off 12VDC give or take. The 12V supply from the battery would be totally adequate for your lights. But in order to incorporate these strips in homes there is the need for an AC to DC converter that will take the 120VAC standard household voltage and convert it down to 12VDC.
What is efficiency of power supply:
The efficiency of a power supply tells the amount of power that actually goes toward making the LED light up. The higher the efficiency percentage of the power supply-the more power you end up saving. For LED applications it is a good idea to select a power source with 80% efficiency or higher. Check out Mean Well and Phihong power supplies for the most efficient selection as they have efficiency ratings running well into the 90 percentile.
How to choose right size for led light project:
When selecting a power supply for your LED project it is important to know where it needs to fit or be installed. If you wish to put it inside the product you are making, it has to be small enough to fit in the space provided. If it is outside the application, it should have a way to mount close by. There are a variety of power supplies offered in different sizes and shapes to fit your needs.
