any suggestions

[Ed Angell]

I would appreciate any suggestions as to a light source that would be
suitable for use in a closed space. Naturally temperature is a big factor
and I can provide a small amount of convection cooling to the structure if
necessary. I don't need a great number of lumens as this light is only an
accent in this piece of sculpture. Providing 110 VAC is not a problem to
power the light source if necessary

Thank you for any suggestions

Fluorescent light produces the least amount of heat per amount of light.
LEDs produce the least heat, but also a very small amount of light.
Could you give more details on why you want the light?

The piece will be mostly black with 2 equal elements and I want this
lighting to accent the negative space between them. Your Idea of the LED's
sounds very workable as the light level needs to be even. but very low
intensity. The light source will also be behind a diffuser with very low
density.

What sort of light intensity are you after?
Try a compact fluorescent bulb, say 60W equivalent, add a diffuser, and
see if it's enough light, or if it's too much.

Neon?

LEDs that feed light into an acrylic light guide. The linear light
guide is a rod of diameter 8mm to 15mm. The LEDs are 1 watt Luxeons in
a housing that slips onto the end of the rod. Search for: Luxaura by
Bridgestone, and for Crosspoint.it under eNeon.

It's quite pleasing if you get a bit or acrylic rod and drill a 5mm hole
in the end for the insertion of a standard LED. If the LED is resined
in, then the lens will disappear as the resin LED case is mated to the
acrylic by the glue. This gives a very good light source in the acrylic
rod.

Just make sure that the hole is slightly less deep than the LED, that
the drill is allowed to spin gently against the end to polish the end of
the hole flat and that the resin is wiped into the end of the hole with
a bit of wire before the LED is thrust in, displacing the residual glue.

Use cast acrylic if the pipe is long > 12 in. or 30 cm. While extruded
acrylic is pretty clear (by most manufacturers), cast is still the king of
clarity.
