Introduction
When people talk about RGB LED flood lights, they normally only know that these lights can display 3 colors: red, green and blue. In fact, there are more. Red, green and blue are the basic colors of each color. Though mixing these 3 colors, the RGB LED flood lights can display many many different colors, such as yellow, cyan, purple, orange, etc. So actually how many colors in total can they display and though which way do they change the colors? We will study in this post deeply.
How many colors can RGB LED flood lights display?
As we know, red, green and blue are the basic colors of all colors. That means any color can be formed by mixing these 3 basic colors. One basic color has 256 grey level, so 3 basic colors can combine 256*256*256=16,777,216 (16 millions) colors! But in the practical applications, not all RGB LED flood lights can display 16 millions of colors. This still depends on what solutions these lights use.
How many solutions are there for RGB LED flood lights?
There are many different solutions for RGB LED flood lights, and the designers or owners will choose the most suitable solutions according to their actual applications. Overall, there are two different solutions. They are internal control solution and external control solution. For the internal control solution, the colors are controlled by the internal programs. Meanwhile, for the external control solution, the colors are controlled by the external components, such as remote controls or controllers.
RGB LED Flood Lights with Internal Control
This kind of RGB LED flood light has built-in controlling IC chips, which storing the programs to display different colors and lighting effects. Once powered up, the RGB flood lights will start running the internal programs and control the colors and effects. The RGB LED flood lights with internal control in the market will normally display red, green, blue, yellow, orange, cyan and purple in turn and some normal color changing effects.
Wireless RGB LED Flood Lights with RF Remote Control
The RGB LED flood lights with this solution are also common in our daily life. The following is one of the normal remote controls in the market.
For the RGB LED flood lights with this solution, normally the users can select multi colors such as red, green, blue, white, yellow, orange, purple, etc. And it supports dimming and multiple color changing effects such as jumping, fading, strobing and smoothing.
Because it is RF remote control, its maximum controlling distance is 10-15 meters.
This kind of RGB LED flood light is also used widely. Normally they are used in internal/external the house, and various kinds of landscape applications.
This kind of flood light is normally connected to the phone via WIFI or Bluetooth, and the colors are controlled on the APP. It enables you to select any color in the spectrum, and providing more lighting effects. Now some new APPs even support Google Assistant and Amazon Alexa.
This kind of RGB LED flood light is normally used inside or outside the buildings or houses. There is limitation for their usages, for some flood lights require WIFI network.
This solution is normally for large projects or those customers who need to control the lights flexibly. These RGB LED flood lights are compatible with DMX protocol (Digital Multiplex). They can be connected to a DMX controller and display any color or lighting effects via this controller.
This type of DMX controller normally has two models. One is SD card model and the other is PC software programming model. For SD card model, there are some programs stored in the SD card and the user can select these programs by the buttons on the controller or by a remote control. And these programs are replaceable. For PC software programming model, the controller can be connected to the computer to be operated by the software, and you can build new programs on the software.
This solution is the most powerful and has the highest flexibility. It is very easy to use its SD card model, but for the programming model, it might require the user has the basic knowledge of DMX.
We have a special wireless solution for DMX RGB LED flood lights, which combines wired DMX and wireless technology. The whole system will use an extra transmitter which will convert the wired DMX signal to wireless signal. Each light has a receiver to receive and decode the signal and commend the lights to display the colors or lighting effects accordingly.
The covering distance of our transmitter can be several hundreds of meters if there are not many big buildings or houses around. This kind of solution reduces the trouble of connection and it has a big advantage on the usage that is you can put the controller in your room, the transmitter on the widow and install the lights outside the building. This is really very convenient!
How to Choose a Suitable Solution According to Your Practical Application?
There are so many solutions for RGB LED flood lights. The user should choose the most suitable solution according to the practical application. For example, to select the correct power, beam angle, color options and controlling ways for the RGB LED flood lights. If you don’t have any idea which solution is suitable for you, you can contact us. We will advise the most suitable and cost-effective solution for you according to your detailed requirement.
