Possible power surge i.e. insufficient power supply

What power source are you using for 24 V power power supply?
Looks like deficiency of required current in the source.

Instead of directly connecting the LEDs to the Power supply, connect them through a series resistor.
No, this is not to solve your problem, but will protect the LEDs.

Cheers!

if connect more leds suitable with power supply the needn't use resistor.
