Power source for two different electronic components

Hello

I'm a woodworker with really minimal technical knowledge about electrical and electronics. I am blue skying an idea about incorporating electronics into some wood lamp designs I have.

One idea is to make a lamp that includes LED strip lighting and also a spot to wirelessly charge your smartphone.

I'm not sure how I would go about determining power supply requirements, and if any fancy wiring or circuitry is required.

For example, I might include:
- a PCBA Circuit Board and Coil (a Qi wireless charger). It has 5V output and Input:12-24V/2.4A. I have used these by themselves before and connect to a USB cable to wall wart or computer
- a length of 12V LED strip light. Stuff I might use is consuming 4.8W/metre.

So supposing I would have 1m of strip in the light and the Qi charger, how would I choose a power supply? And, what is a good way to manage the wiring inside and small lamp assembly?

Thanks

Paul

Determine the voltage and current requirements for the lamp. If other than 120 vac, purchase a power supply (PS) that will provide the required voltage and current as a minimum, If the lamp requires DC voltage, the PS will be a ac/dc type. The PS can be remote from the lamp with several feet of wire connecting the PS DC output to the lamp

We'd like to see some of your lamps...... How-to-insert-pictures

It's a great idea to use a plug-in adapter as it keeps all the wiring in your lamp as low voltage.
No worries about unsafe shorts or high voltage wiring.

Well shucks

Here is a screenshot from my instagram. The lamps I am making in the future will be sort of smaller version of these floor lamps, with the addition of wireless charging in the base.
