You will need a heat sink when you use a COB LED in your luminaire. The traditional way of transferring the heat away from the light source is to use a passive aluminum heat sink. In this blog post, I’ll introduce you the new way of cooling: heat pipe. Traditional heat sinks are based on the…
We redesigned our aLED-modules based on customer and market feedback. Here is a brief explanation on what is different compared to previous version. And why I think you should consider using aLED modules. Better efficacy (159-191 lm/W) We upgraded the SMD LEDs used in the modules to better suit our customers’ needs. aLED modules…
I would like to thank everyone who we met at the Elfack Exhibition in Gothenburg, Sweden. We had some good conversations with our existing customers as well as new people. This year we tested the color quality of Citizen’s LEDs at our stand. We got many answers through our questionnaire and found out that many…
Elfack exhibition will be held in Gothenburg, Sweden from 9th to 12th of May. As it has been with previous exhibitions, we will be releasing new products and presenting the latest technology at our stand. This year we will introduce and present the following products at our stand F04:70. aLED Engine We designed aLED Engine for…
What is AC COB? AC COB is brand new AC LED solution from Citizen Electronics. It is available with holder which contains necessary components to connect package directly to mains voltage. So basically it is designed to make life of luminaire manufacturer easier. What advantages? AC COB has integrated circuit which allows you to control…
Citizen have released generation 6 from their successful series of Citizen COB LEDs. In this post I’ll go briefly through, what is new and what advantages these COBs have compared to previous generations. There are five main points at generation 6 from Citizen: 1. Performance increase Performance will up to 7% depending on CRI of LEDs.…
Datasheets are essential part when you compare how different light sources work in your solution. Usually it can be time taking and exhausting to glance at datasheet and find values you are looking for. This gets even harder if you have multiple LEDs or different LED packages, which would mean that you have look at…
You can use several different dimming options to dim LED Lighting. What are the possibilities and what dimming should you look from a LED driver? I’m going to answer these questions in this blog post by going through the different systems. The goal is to give you the basic understanding of the dimming methods available…
We see more and more light sources that supposed to be exactly the same color temperature, but actually appear different to human eye. So why the same color temperatures look different? When people talk about color temperature, they are usually talking about correlated color temperature instead (CCT). There is a difference between these two. Color…
The selection of Constant Current driver is not always that simple, Esko wrote a post about it some time ago. You can read that here. Below you can find an infographic about the same topic. If you like it, feel free to share. Here is a link to our Lightbuilder.
