LED DownlightWhen contacting LED equipments, sometimes we come across two different equipments, LED Downlights and rgb LED flood lights. So what is the difference between them?LED Downlight is also called LED spotlight, LED castlight, LED shoot light and so on, it mainly used for architectural decoration lighting, and commercial space lighting, decorative elements are heavier, its appearance is round and square, because generally have to consider the cause of heat dissipation, so there are some differences between the shape and the traditional spotlight.
features of LED Downlight:At present, the commonly used LED Downlight in the market basically choose 1W high-power LED(each LED component will have a high-efficiency lens made of PMMA, whose main function is to distribute the light emitted by LED, namely secondary optics). There are also a few companies that choose 3W or even higher power LED due to the good heat dissipation technology.Suitable for large occasions, such as lighting, building lighting.
rgb LED flood lightrgb LED floodlight is a point light source that can be uniformly illuminated in all directions. Its irradiation range can be adjusted arbitrarily, and it is shown as a regular octahedron in the scene.Floodlights are the most widely used light source in rendering.
Standard floodlights illuminate the entire scene. Several floodlights can be used in the scene to produce a better effect.Floodlight is a kind of illuminant with the most extensive application in effect diagram, in setting can use much floodlight to coordinate action, in order to produce better effect.
Features of rgb LED flood lights:The best analogy to a light bulb and a candle is to shine an object uniformly in all directions from a particular point. Floodlights can be placed anywhere in the scene.For example, it can be placed out of camera range or inside an object.
It is common to use many different colored flood lights at great distances in a scene. These floodlights can cast shadows and blend them into the model.Because the illuminative range of floodlight is bigger, so the illuminative effect of floodlight is very easy to predict, and this kind of lamplight still has a lot of auxiliary use, for example, place floodlight to be close to the position of object surface, can produce bright light on object surface.
Pay attention to, that rgb LED flood lights should not be built too much, or renderings will appear flat and rigid. Therefore, we should pay more attention to the effect of lighting parameters and layout on the light sense of the entire effect diagram scene in the usual rendering, and accumulate more experience to master the lighting collocation skills.The difference between LED Downlights and floodlightsThe distinction of rgb LED flood light and LED Downlight is shown not only on illume vision effect, the matters needing attention in using to rgb LED flood light and LED Downlights also differs somewhat.
The difference between rgb LED flood light and LED Downlight is that rgb LED flood light cannot be built too much, so in the visual effect will appear flat and inflexible, in the production of more attention to experience the light parameters and the effect on the whole picture scene light sense. The distinction of rgb LED flood light and LED Downlight still behaves on the illuminate range between them, LED Downlight is called again cast shoot the lamp, spotlight, shoot the lamp to wait, basically do architectural adornment illume and commercial space illume, its adornment sex composition is heavier, design kind is more on modelling design.A rgb LED flood light is a kind of uniform point light source that can shine in all directions and places, and its irradiation range can be adjusted arbitrarily.
A standard rgb LED flood light can be used to illuminate the whole scene. RELATED QUESTION I didn't get Google Glass Explorer Edition. Is trying to learn Glass dev without the hardware a futile effort?
No, you can still learn the fundamentals of Glass development without the hardware. There are three main approaches for accomplishing this: 1) Visit the Mirror API documentation, get into the playground, and start hashing up some code. Download the PHP, Java, and Python library, whichever you're most comfortable with.
Familiarize yourself with the jargon and converntions (timeline, bundles, menus, etc). Read the support documentation (second link below) to see how the Glass hardware actually functions. Build some apps to this specification.
Soon enough, you will find a friend with hardware to t
