Types of LED Light
Let's talk about the different types of L. E. D. Lights are three basic types. This can get a little technical so we're gonna try to spice it up and make it fun. So we're I have a power point slide here to spell this out. So the three types are D. I. P. S. And D. And C. O. B. Let's begin by talking about dip that's dual in line package. These are the LED lights that you see on all kinds of electronic devices and in your car remote and the stuff that annoys you at home. Little light on your T. V. In fact we have uh some on our soundboard right now and you can see them. They are just little flashy things like that. So this is these are the LED lights that we have grown up with and know and love those are not the type of LED lights that we use in constant light. That's not what we're gonna be using I think many years ago people did use some of those to try to light some stuff but they're just not bright enough. And so really what we're talking about constant light, we begin with the secon...
d type of LED lights And those are the S. M. D. Surface mounted devices. Now this let me just read this to you. So we have three diodes per chip or more. And that allows these chips are these diodes these LED lights to change color and they are much smaller and they use a lot less energy. They're more efficient than the old school lights that we showed you on. The little sound counsel. So I have some here that I want to show you. And so I've got these two little light panels here and one of them you can see really clearly these Fc and D. Chips and the other one still the same thing but it's got a screen in front of it so it's it blocks that. So what I'm gonna do is I'm gonna take this guy, I'm gonna turn it on and lamb. Oh when it turns on you can see that we have all of these little diets, these little chips that are illuminating brighter and darker and so what we can also do is change the color and notice that when I'm changing the color. One of those lights is turning on, the other is fading out and it's going back and forth. So these are two white chips, we're gonna talk a little bit more about that. This helps us to adjust the color temperature between a more warm light or color temperature like a 32 100 kelvin up into something that's got more blue Which is like a 5600 Kelvin and back and forth. So we can control white with different colored white chips and we have the same thing on the other guy over here. I turn this guy on, it's the same thing, you can see that the color temperature is changing I think. Yeah. There we go. You see it's much more amber, it's much more blue. So we're changing our colour temperature but this is a white panel, we'll turn that up a little bit, you can see that. So these are these are just normal LED lights, smd lights where we're changing the color temperature between uh an amber to a more bluish color. So this is 3200 kelvin to 5600 kelvin. So um 3200 emulates tungsten lights. 5600. When we go to a more bluish light emulates sunlight daylight. And so that's something that you can't do with tungsten lights. You have to use gels to make those changes. Now there's a third kind of LED light and these are the latest and greatest and really amazing. And these are called C O B lights chip on board. Now what we do is in technical mumbo jumbo, this is when you mount bear LED chips directly in contact with the substrate. So you're putting it on the silicone on the board itself, it's the most efficient thing. They're going to get the most light output per watt. And you can put a bunch of different diodes for color control. So you can do RGB white, different colors of what you can do, all kinds of really cool things. So Theresa is going to bring out one of these fancy ship on board lights. Thank you so much and then we can show you what this looks like. So there you see that's the front of that, you can't really see the individual leads anymore. So it looks like one big thing and if I go to the side you can see there we go. It's flat it's very very thin. So this is chip on board so it's mounted on the board itself. Now let me explain sort of the differences between the D. I. P. And the S. M. D. And the C. O. B. So when we look and we compare how many leads we can get in a very certain amount of space. So if I have uh 10 millimeter by 10 millimeters space I have a little diagram here. You can see that in the D. I. P. Lights of the old school lights, you might put nine of those in that space. They're not very bright. Smd the second light, the little LED that we showed you in that same amount of space. You can have 40 different led lights. And inside of those 40 different led lights that can be multiple colors. You could have uh amber light and a more bluish light. You could have red, green and blue. You can mix it all up but in the same amount of space chip on board you can have 342 LED. So they're all smushed together and you get really amazing um light output and it doesn't consume a lot of electricity because it's more efficient. You're not having multiple things. So that's sort of the technical thing. There's one other thing I want to um review and that is when you're looking at RGB lights, we have a difference between RGB, RgB W in a RgB W W. So what is that? Well, RgB is red, green and blue. If you mix red, green and blue in light, you can get any color that you want. So we have that, then we have RgB W and that is red, green and blue and white. Why would we have that? Well, there is one serious drawback to L. E. D. Lights and that is that in nature we have a full spectrum of light from the sun. So we have from our blues to our yellows, to amber, the whole rainbow, we have an equal distribution of light and we get all the colors there in diodes, You don't necessarily have that depending on how they're manufactured in the quality you get a little dips. So you might have in a blue diet, you might not have all of the blues, you might not have all of the reds or all of the greens and yellows or whatever. You might have little pockets that you have color that's missing now to our bare eyes, you don't really see that, but when you take photos or you're making videos, it does show up on the camera. And so what will happen is if you're trying to get white light and you're mixing red, green and blue, you might not actually get all of the colors in the rainbow, and so you'll have weird spikes of color or were dropouts where things have a strange tent or something. So to correct for that, what manufacturers do is they do red, green and blue. So you can mix and create all nifty colors, but then they add a white chip there and that white is what's used to create white light. Remember when I showed you earlier when I was changing the color temperature of that little panel, we had two diodes there, one was an amber white light, one was more of a blue white light. So we have RGB W W, so that's red, green, blue, white cool, so white, like 3200 kelvin, the cooler uh, temperatures. And then white warm, which is maybe up to 50 to kelvin, and then you mix between those two whites to go the full range of white light. And so that's why you have, when you're buying lights, sometimes you'll see RGB RGB W. RGB W W. So if you're doing video and you want to be able to mix all the different colors and also have nice uh, white light that you can color correct, then you want RGB W W and we've got some of those lights with us here, we're gonna be working with those a little bit later on. Okay, now that, you know, all these technical things, the bottom line is if you want to mix colors and have some really groovy effects, you need an RGB light on RGB W W light, we have some nanotubes and stuff that we'll be using. Um If you just want to have a really high output light, you need to have a C. O. B. Light and so that's going to be the most punch. If you really need a lot of light, you need a C. O. B. Chip on board light, that's what these guys are back here. Um and then you can mix and match all of those things and it's gonna be a lot of fun. So what we're gonna do next is we're gonna talk about how we can control all of these different lights and put them into practical use.

Great course very informative and a pleasure to watch love the way you teach so easy to understand and follow through. learned a lot about continuous lighting ty

This is a very useful class for who want to start shooting video or photo with constant light. Creative Live should make more class on videography.
