Instead of heating up the bulb to produce light the led uses semiconductors that bond atoms with surrounding diodes to create power.
Led light bulbs no heat.
The energy consumed by a 100 watt gls incandescent bulb produces around 12 heat 83 ir and only 5 visible light.
There is no source of heat necessary to form light.
In contrast a typical led might produce15 visible light and 85 heat.

In contrast the led has no.
The heat produced by an incandescent bulb is largely emitted in the form of infrared radiation so it heat up everything in the room around it.
In addition there is heat conducted into the air by the bulb and the base.
Especially with high power leds it is essential to remove this heat through efficient thermal management.
