According to foreign media reports, a German company called Ledo has created a new LED bulb . These bulbs look similar to incandescent lighting, but they are fundamentally different. 
The new LED bulbs are made of solid aluminum. They are equipped with 11 super bright LEDs with a light distribution angle of up to 330. The lighting capability is comparable to that of a 60 watt incandescent lamp, but the actual power is only 11 watts.
In terms of heat dissipation, the traditional way is to add a heat sink. But these LED bulbs don't do this, they are implemented with a conical shape design. Because the cone can form a variety of "ventilation ducts", which helps the bulb to transfer heat and achieve heat dissipation. In addition, these LED bulbs have an extremely long life of 80,000 hours, which means that each bulb can accompany you for more than nine years.
