Explore Led Signs, Rooftop, and more!

Diamond Vision flood beam CRT's. Predecessors to today's bright RGB LED's in large display signs. They differ from the CRT tubes used in old monitors by being small, and having a nonfocused electron beam “flood” spraying onto single color phosphor. Diamond Vision once had a rooftop sign near Times Sq. at 47th@7th, but large LED signs have now taken completely over.

An unmanned aerial vehicle you can throw in your rucksack and bust out later for mid-expedition filming | You can program 3D flight paths with its autopilot software, fly it yourself with RC, or have it automatically tail you in the wilderness. It’s like a hiking buddy—except it’s battery-powered and doesn’t complain about blisters or eat your trail mix.

If you look closely at the "filament", you can see the individual LED dies.

How do filament LED bulbs work, looking very similar to incandescent bulbs?

Philips Illuminate, partly controllable RGB LED set. Control is with mobile app. Limited control-ability now, but can be improved with software updates. Also adds warm white LED inside module, so it can switch between color and warm white (cool white is made with RGB).

In the lighting district of Chinatown, the lamp stores are filled with bulbs using these LED rods that emulate incandescent filaments. They actually contain rows of tiny LED dies in a substrate coated in the yellow phosphor (which turns the emitted blue into white. Both "soft" and "cool" white are available).

Filament LED bulbs use very narrow strips containing the LED, which look similar to filaments of an old incandescent bulb: They look like a normal bulb with large "old-style" coal filaments, and a.

Whenever you see a traffic light with a yellow sun shield, you know the scene is in Canada. (Fairly recent example, city scenes in "Pixels").

My own BetaBrite Prism (from Amazon, for an amazing $69; when it's worth about $300 new!) showing off the colors (which are distorted by the photography), and how it can be used for transit. I have been putting it in the window with holiday messages for the past few years.

Philips comes out with a "mini" version of the new Illuminate lights, and even though the program was updated to allow you to make "soft white" with RGB, it still squeezes in a separate 2700K die.

Not NYC Deskeys, but train set models. They do resemble what Baltimore had on its highways decades ago. I called them "gas station lights", as shorter versions were common on service stations everywhere. Both Harlem and Hollywood had poles with longer fluorescent luminaires like that, in the past.
