Application Notes:
Please ensure that when connecting to supply, the correct polarity printed
on strip is observed.
Use of a regulated 12V DC supply is recommended.
To prevent voltage drop, a power feed at each end is recommended for
chains longer than 5 strips in length. For very long lengths it is recommended to connect a power feed after every 10 400mm strips.
Cut only at designated cut-points, which are positioned every quarter-strip.

PCB Layout:
PCB comprises 3 chains in parallel, each with an open central link and consisting of 4 LED pads in series. Circuit diagram is given below.
Note: LED pads are shown populated for ease of illustration. Actual population varies from strip to strip as explained overleaf. Some pads may therefore remain unpopulated.
Page 11
Standard populations:
Strip dimensions (4 LED population shown)
PCB pads are designed to accomodate TO-220 High Power LEDs. Standard populations are shown in the table below. Unpopulated pads may be populated with loose TO-220 High Power LEDs through the use of thermally conductive adhesive.

Application Notes
Precautions:
Current should be derated in order to keep junction temperature below maxmum by reducing power dissipation.
Current spikes should be avoided especially during power up. It is good practice to initially connect PCB to unactivated supply, then gradually ramp up voltage to desired value.
Proper management of the thermal path should be observed. Adequate heatsinking of strip should be provided in order to maintain junction temperature below maximum. Proper thermal conduction layers should be introduced at all interfaces to prevent insulating air gaps in the thermal path.
If the LED package has a lens fitted, note that the lens should not be taken above 110 degrees Centigrade.
It is recommended that a constant-current source is used for the driving of these LEDs.
As with all semiconductor devices, it is good practice to avoid electrostatic discharge (ESD).
