That made things clear. I wasn't able to find that information myself. Thank you very much Ulrich, regards.

I answered a similar question a while ago, please have a look here for details about the advertising data. Please also look in the comments of that answer for some extras.

Please let me know if there are something that wasn't clear enough. To decode advertisement structures, you might need to download - or find a reference to - the core spec supplement pages.

Structuring your data in the same format yields this:

Length | Type | Data
  0x0B | 0x09 | 0x4C, 0x45, 0x44, 0x5F, 0x42, 0x6C, 0x69, 0x6E, 0x6B, 0x79, 
  0x03 | 0x19 | 0x00, 0x00, 
  0x02 | 0x01 | 0x06
  0x0B | 0xFF | 0xDE, 0xEF, 0xFF, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00, 0xFF

The first two bytes of the Data in "Manufacturer Specific Data" (Type 0xFF) make up the company identifier. The rest of the types are explained here, with more detail found in the Core Spec Supplement. This includes data lengths, formats etc.
