The first article of this 3-part blog post series was dealing with the near-term history of European directives and regulations related to energy efficiency and different energy-related products (ErP), not only energy-using products (EuP). Starting from Kioto 2005, this process has then proceeded to the situation, where new kinds of regulations have been taken into…
Generally, we can say that LEDs are environmentally friendly and recyclable. They have a long lifetime and low power consumption. They don’t contain hazardous substances, for example, mercury as compact fluorescent lamps do. In this blog post, I will present to you four environmentally friendly luminaire component choices. LED That Don’t Need a Driver Have…
Nowadays LEDs have great efficacy and lifetime. They produce more and more light with less power. I think that it’s less important to increase efficacy because we have already reached what the market demands. What else we need from the light than a lot of lumens? In this blog post, I’ll compare the differences between…
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…
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…
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…
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.…
COB LEDs are very popular nowadays in LED lighting business. We talk and write about COBs, and our customers use COBs in their luminaires, but what exactly is COB? First of all, the abbreviation COB comes from words Chip-on-Board. In COB packages many LED chips are usually attached to substrate with non-conductive adhesive. LED chips…
