NO WINNER??? Great job CADCROWD... another unsuccessful contest. I feel there needs to be a penalty or something when this happens. Also, the client should not be allowed to hold another contest on this site. Lots of work and time go into designing these products.
Hey, hi! I&;m just wondering since you mentioned only the height and width of the LCD panel, can I have the freedom of design the case with a long tear drop rear? I&;m a professional car designing student and trust me, I can make a cool looking streamlined case if you can accept having a case with a lengthy extension in its rear.
Hi,
I&;d like to ask some questions.
The picture shows a grid of 37x8 LEDs. Is this your current grid or the picture is a general example. Secondly, do you need the 5.08cm clearance over the entire depth of the display panel or the case may curve around the top and bottom of the display panel.
Thanks
If you want casing with ventilation holes, then IP43 is the max you can get. For IP67 the whole casing should be sealed and ready to be immersed under water, so there should be no holes at all. Moreover lower IP number means lower costs. Please consider IP43 instead of IP67 and let us know if you want entirely sealed casing or just the casing resistant for all weather conditions.
Please specify what is the quantity you want to produce, as it affects technology and hence the design.
That&;s an awful lot of high-output SMT LEDs. My first concern of many is thermal dissipation, is this device completely programmable by the end-user? If so then there is the possibility that the end user would turn it into a full-ON light bar for any amount of time. Have you noticed the device generating a considerable amount of heat during your testing? This will let me know whether the back can be enclosed or whether it needs to have heat exchanging fins. Thanks!
This seems like an interesting project. I have a couple questions about your requirements.
What is the max speed of the vehicle? This will determine how much force the sign will see from wind, and how much G-force it will see during emergency stops.
What is the pitch and diameter of the LEDs?
Regarding aesthetics, do you have a preference for sharper more "boxy" edges, or do you prefer a more "rounded" or "organic" design?
What is the quantity that you plan on manufacturing? This is really important. It will dictate production methods and some design features, as well as material selection.

Have a look at a product called a Roku it is a case that is simple and cheap in manufacturing cost minus the ends. In particular take note of the housing. A simple aluminium extrusion with caps where the electronics slide into place. (Just a real durable design that would work for your application.
