by Krista Disano These instructions may be used to create a small LED mount (using a 16mm cage plate to mount the LED) or a large LED mount (using a 30mm cage plate to mount the LED). One advantage of using the larger LED system is the dispersion of heat from the LED onto the cage plate. However, if you plan on assembling a larger LED system, the increase in weight from a larger cage plate will lead to less stability when mounted onto a cage rod. The system may not stay in place at certain angles. Make sure you check this before assembling! The excess heat emitted by the LED can also be resolved by mounting a heat sink on the back of the cage plate. I would recommend that both systems use heat sinks. Otherwise, the LED’s may burn out with prolonged use. MATERIALS:
INSTRUCTIONS: The following assembly is for a small LED illumination system (Notes will be made if you need to modify a step for a large LED system). 1. Take the aspheric lens and mount it into the cage adaptor plate (#sp05) 2. Add the 4 mini cage assembly rods (#SR1) into the holes closest to the lens. If you are making a larger system, the rods (#ER1) will be on the outer 4 holes. 3b. For the small system, the LED must be cut down using the dremel. Beware of the connections when you are trimming the LED. If you are using a large system you will not need to cut down the LED. Solder the BNC lead onto the LED after it has been trimmed. The wire coming from the center of the BNC lead is positive, while the outer cable is negative. Attach the LED to the cage plate with arctic silver. 4. Add on a heat sink to the opposite side of the cage plate with the LED. Be careful that the heat sink is not overlapping with the cage rod holes. Normally these heat sinks are stickers so they can be stuck right on; one could also use arctic silver thermal adhesive (be sure to get the thermal adhesive, not thermal paste). |
