LED Architecture Design Concepts
T-type of LED

T-type of LED

The T-type LED is the righinal style Because the sealed casing does not allow heat to dissipate, this style is not suitable forhigh luminous power applications, but only as a signal/readiness indicator.

SMD of LED

SMD - Surface Mounted Device

With the SMD, Surface Mounted Device style, the component is adhered directly to the printed circuit board. the output ranges differ considerably here. On many LED with a small single-power source, series resistors can be accommodated in the luminaire, and connected in parallel to constant-voltage LED transformers (similar to halogen luminaires).

SMD High output LED

SMD - High Output LED

With the SMD type of individual high output LED (here an example of a luminaire with an energy efficiency of approx . 50 lm/w developed in 2003), the luminaires should be connected in series to constant-current LED transformers (unused sockets must be provided with short-circuit plugs).

SMD - High Power LED

SMD - High Power LED

With the new high power SMD style LED (here an example of a luminaire with an energy efficiency of 80-100 lm/w developed in 2008) the luminaires should also be connected in series to constant-current LED transformers (unused sockets must be provided with short-circuit plugs).
