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…
In my earlier post I went through the procedure of how to physically connect a single LED component into an AC network. The connection was made between COB LED and the LED driver. When connecting LED modules (LED diodes assembled on the PCB board) you do it pretty much the same way with slight differences.…
I have two blog posts for you focused on how you connect COB LED components into the electrical network. I mean, when you have either a single COB LED or an LED module based on SMD LED components assembled on a PCB board. Compared to traditional lighting, connecting LEDs to the electrical network is a whole…
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.…
When we talk about color rendering, traditionally that conversation has been filled with CRIs and Ra-indexes. These traditional ways of telling how well certain light source represents sunlight have been criticised because they may not tell the whole truth. In recent years, LED manufacturers have been trying to answer this criticism by creating different products.…
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…
OLED means Organic Light Emitting Diode. It works in similar way than (semiconductor) LED. Both need positive and negative charge carriers to generate electrical current and finally generate light. It is a surface light source based on organic material layers. LED, on the other hand, is a point light source that is based on semiconductor materials. But…
From this post, you can find the most frequently asked questions related to OLED panels. The post will be updated in the future if new questions arise. Q: What is OLED? Does it work in the same way as LED? A: OLED means Organic Light Emitting Diode. It works in similar way than (semiconductor) LED.…
The world market for OLED Lighting will grow to 1.6 billion US Dollars in next five years. This year the market is estimated to be 135 million Dollars. This is according to UBI Research. The situation is similar to LED market in 2007. When we introduced Citizen LED to our customers in 2007, many held…
