2nd Generation 5W LED Bulb 230VAC

Neat little 2nd generation 5W LED bulb using the remote phosphor technology. This is bulb is built using low tech methods as it is essentially hand assembled from the various components as shown.
This bulb needed proper ventilation to operate and will not operate properly in a enclosded lamp shade as overheating will shut down the bulb.








 
To allow for additional heat transfer another aluminium disk
is added to the LED module. This become necessary since
the design of the main heat sink body did not faciliate a large
contact surface with the LED module. Surprisingly this is effective
in sinking the heat to the main bulb body as it is become hot to
the touch when in operation.

The various parts of the 5W LED bulb. LED module, heat sink
lamp base, driver module, clamp ring, insulation paper, tape
to hold insulation around the driver module.


Inside look of the main heat sink body of the LED bulb.
The large cavity reduce the heat sinking ability, but is needed
in order to house the driver module.
