Introduction

The solar spectrum is an absorption spectrum of different wavelengths. It is divided into two parts: visible light and invisible light. Visible light has a wavelength of 400-760nm. After being scattered, it is divided into 7 colors: red, orange, yellow, green, cyan, blue, and purple. When concentrated, it becomes white light. Invisible light is divided into two types: infrared light, which is located in the outer area of ​​red light, has a wavelength greater than 760nm and a maximum length of 5300nm.… Read More

Before knowing how much money is needed to light up a football field, you need to know the size of your football field and the sport level of the football field, so that you can roughly know how many wattage lights you need. After knowing the wattage, you will know the cost of the lights and even the related electricity bill.… Read More

Dali and DMX are often compared for comparison, so what is the difference between them?

What is DALI?

DALI stands for Digital Addressable Lighting Interface.

DALI is a two-way digital communication protocol, developed to manage networked lighting-control systems used in building automation projects. A trademarked international standard, DALI enables smooth hassle-free integration of LED gear from diverse manufacturers – equipment that can include dimmable ballasts, receiver and relay modules, power supplies, dimmers/controllers and more.… Read More

One aspect that makes LED lighting unique is the various color options available. Many are familiar with the different light temperatures: warm white, cool white and natural daylight. Though, RGB LEDs are also growing popular for their beautiful colors, along with the versatile uses and benefits. Want to know what they are? Well, here we go…

What is RGB color?

RGB is an acronym for the colors red, green and blue.… Read More

With the advent of LED technology more attention needs to be paid to the way light fittings are controlled.  Switching LEDs is very straightforward but dimming is a bit more complicated.  There are different ways of dimming (see below for the different dimming types) and the type of LED Driver needs to be matched to the control system in use.  It is also recommended to test drivers and dimmers together; even if theoretically compatible, they aren’t always so in practice. … Read More
