Hi everyone,

I have a Pure Tempus-1 Digital Radio and the LED light has stopped working. It is very difficult to see the LCD display now, so I was wondering if someone could recommend me a very bright LED component, so I can put this next to the LCD display to light the screen back. I have measured the voltage in the broken LED and it is getting 4.5V.

Thank you
 

An LED is fed a current with a voltage high enough to light the LED.
A white LED clamps its voltage to about 3.2V. Then if the 4.5V is fed through a 68 ohm series resistor the current in the LED is (4.5V - 3.2V)/68 ohms= 19.1mA.

Usually a very bright LED has a case that focusses and concentrates the light into a very narrow beam. Instead you probably want an LED with a wide viewing angle then its rated brightness is less than an LED with a narrow angle.
 


Thank you for your very clear reply. If I understood you correctly, the best solution would be to use a 3.2V wide angle LED like this one https://i.ebayimg.com/t/50pcs-6000MCD-5mm-straw-hat-Yellow-LED-Wide-Angle-3-2v-/00/s/NTUwWDU1MA==/$(KGrHqV,!hUE5qnL01SiBOcJiIu-dw~~60_3.JPG.

This is the pricture of my radio, so you can have an idea about the LDC display **broken link removed**

Would you mind to recommend me a specific LED?

Thank you for your help
 

The wide angle LED looks like the ones in my cheap solar garden lights.
Since the radio uses only one LED then maybe it has a diffuser to spread out the light. Then nearly any white LED will work.

Thank you, I will try with a random white LED and I will see what happens.
