Why does an LED PCB need a heat sink?

The supplier whom I ordered LED PCB design is asking details of LED heat sink, but actually we have no idea about it. Why does an LED PCB need a heat sink? This is a new project for our house supplies brand. Any tip can inspire us?

LEDs cannot suffer high temperatures. Most of the energy wasted by an incandescent bulb is radiated away from the filament as infrared energy, and since the filament operates at a white-hot temperature, the bulb is made to withstand that temperature.

LEDs have to be operated at a much lower temperature, and all of the waste heat is removed by conduction and convection, which requires a heatsink.
