COB LED Technology

February 7th, 2013 Posted in worth knowing Tags: , , ,

Flat as a cracker – that is how the future of High Performance LEDs appears. And in this flat lies the secret of the powerful LEDs. Because the latest generation of high-power LEDs is characterized by COB (Chip-On-Board) manufacturing.

Advantages are a better heat dissipation, a minimum chip distance and an easy control of the LED arrays or LED clusters (also called modules).

Warm white, cold white – do you know why?

November 29th, 2012 Posted in worth knowing Tags: ,

For a lot of our spots, we indicate the temperature of the white light. However, that has nothing to do with the warmth of a spot, but with the „color“ of the white light. So why are we talking about temperatures?

To explain that, we have to go back in time. The famous men, who essentially contributed to classifying colors by temperature, were Lord Kelvin and Max Planck. In the 19th century, the latter found out that a black metal body glows in different colors when heated by electromagnetic radiation. The higher the temperature of the metal, the shorter the wave lengths of the light emitted by the black body. That means: The body starts glowing in a in a dark red color at low temperatures and becomes brighter and brighter. In those days, temperatures were measured in the unit „Kelvin“, named after the Lord. This way, the classification of colors in degrees Kelvin developed. Concerning color temperatures, the prefix “degrees” is not used nowadays

This is why we still speak of color temperatures today. Take this as a rule of thumb: The higher the color temperature is, the cooler the light appears. A warm white is at 3300 K, a cold white at approx. 5600 K. Sun light, by the way, is a „cold“ white at almost 6000 K.

So if you see a spot with the description „warm white“ or „cold white“ in future, you know exactly what it means. By the way: Warm white colors create a rather harmonious mood, cold ones create a more realistic daylight atmosphere.

Import orders in the online shop

November 6th, 2012 Posted in worth knowing Tags: ,

Some of our customers do not order online yet, because it seems to be a big effort for them. That’s true if you want to add 56 single articles to your cart. But there’s a quick and easy way to order many articles online:

That’s what the import function in our online shop is for. With that function, small orders as well as big orders can be imported  effortlessly and quickly.

Here’s how it works:

1. First you need to log in.

2. When logged in, you can go to your cart and…

3. …click on „to cart“ in the right corner.

Now you see your empty cart. You can now import your order.

4. Therefore, you click on „Cart import CSV“ and then on „choose file“ (5.).

6. Now all you need to do is choose the right file with the stored data for your order.

7. As soon as the order has been chosen, you can start the import by clicking „Import“. You’ve got the possibility to add your imported order to your cart or to replace the cart by your imported order.

You can immediately see the prices of the articles now and if they are in stock. If you want to, you can change the amounts now in order to adjust them to the packaging units. You can also add other articles.

That’s how the CSV should look like:

article number; amount

e. g. 51704210; 5

Have fun importing!
