Hi all,
Sorry for not being clear. My company makes commercial lighting fixtures and we do have our own photometric testing rig, which is a rotating mirror goniophotometer type of rig. The data comes in raw form. I'm trying to learn how to convert this data into IES format. The raw data is in...
Hi,
I'm fairly new to lighting design. I have an unhelpful boss, who can't seem to help me in anything. Anyway, I'm writing this to ask for help on the conversion of photometric data into IES format? Any suggestions on how to convert or what literature to read up on will be appreciated.
Thanks
Hi,
I'm currently trying to design an enclosure to withstand an explosion. But since my company had refused to purchase a Cosmosworks software, I'm stuck with the express version. Anyway, I had done the design for the body with 4 constraints at each of the corners on the base of the box. Since...
Wow, thanks for everybodies help in my clarification. I had learnt much more about SS316 than I already know. Ok, one of the main concerns when I asked this question is that the customer may decide to try a magnetic test on the boxes to see the composition, so right now it will fail the test. At...
Hi guys, the following is what I managed to obtain regarding the properties of the castings.

Hi all, my company produces explosion proof boxes for hazardous areas. Recently, a customer asked for 4 boxes to be casted in 316 stainless steel. We just received them today but the boxes are attracted to magnet and seems to be a bit rusty too. My question is whether this is normal? I've always...
Ok, I'm not sure whether my suggestion has a name for it or whether it's mentioned. My suggestion is to use a long threaded rod with the pitch travel you wanted per revolution. Add a coupling at one end so that a motor can be attached directly or through a step down. Next, put a piece of metal...
Just use assembly and assemble the parts together. If there's only some differences between the parts but have some identical features on the faces. Assemble at the identical features and just play around. Example, assuming each of your two parts has a square face. Mate at the face and...
Hi, I'm currently helping a friend to improve his charcoal burning business. It generates lots of smoke during burning and I'm thinking of making special vanes that utilizes airflow to create vortices to help suck out the smoke and expel it to the atmosphere, at the same time it should help...
I get the point about the oven. The problem is that this so called oven doesn't have any temperature control switch. It's not really an oven but it does look like one. It's more like a barbeque pit. What I'm doing here is to sense the temperature and cut off the air supply to it, thus...
Hi, currently I'm in a bind. I'm trying to make a temperature switch which can be used to turn off power to an oven. As I'm on a budget, I can't go for sophisticated stuff. I measured the potential difference of a thermocouple but since it's in mV. I can't do much with it to trigger a relay. Are...
