Ignition Risk Due to Optical Radiation
It looks like this IEC standard (EN-60079-28) might not actually apply to luminaires anyway, from a draft document I found on the web. We’re looking into it, since it makes sense that there should be some limitations on optical power for HazLoc. Here’s a ballpark analysis, which indicates the CRS Electronics luminaires are not likely to be an ignition source due to the optical radiation emitted. However, if we maxed out the drive current for a luminaire, the optical flux can exceed the limits set by the IEC.
Immersion and Condensation Testing
Condensation has been observed in the head of an early luminaire fixture installed in the field at the Manitouwadge Airport. A sample luminaire was repurposed for R&D evaluation and subjected to condensation and immersion testing. No evidence of condensation was observed after multiple warm-up and cold water immersion cycles, indicating that the fixture is well sealed at least when manufactured according to assembly instructions. However, some concern remains as to the long-term effects of pressure cycling the luminaire head with repeated warm-up/cool-down cycles.
Thermal Testing
This is a study of a luminaire device under various environmental conditions. The testing proceeded in 3 parts. The first part was a 1000 hour test which cycled temperature between -55°C and 105°C while turning the power to the light fixture off and on again. The second part was a 24-hour high temperature soak, where the device was kept at the temperature of 107°C, and while the power to the device was turned off for 2 hours and then turned back on for two hours, and repeated until test conclusion.…
Hydrostatic Pressure Resistance Test
This is a study of hydrostatic pressure resistance of two different lighting fixtures. As per “Device Pressure Testing” quotation, two separate devices, were first filled with oil, attached to our DHI pressure generator system, and then submitted to hydrostatic pressure.
How to kill a mosquito at 30 feet
Interesting question… Are we talking vaporize, ignite, or heat up until death for the mosquito? I’ll assume we want to minimize damage to surroundings so let’s just heat them up till they stop functioning. We’d need to figure out the temperature at which a majority of mosquitos will die. Since they seem to love hot weather, let’s assume we need to hit 100°C for them to fry. Estimating the average absorption coefficient for a mosquito when illuminated with the spectrum of your favorite LED source (50% of incident radiative power…
