Sažetak
The subject invention is a portable illuminator for external photodynamic diagnostics for medical and cosmetic purposes, which can also be used for photobiostimulation which, as a light source, uses a new type of lamp that emits light of wave lengths that can be found around the absorption maximum of a photo-sensitizer, which is consists of a considerable number of light-emitting diode crystals that are closely and evenly spaced in two dimensions upon a base which conducts thermal energy and insulates electrical energy. This new type of light source, consisting of a considerable number of highly effective small, light-emitting diode crystals, was named "Cluster LED", which means a lightemitting diode cluster. The cluster is fitted into a reflector of suitable shape - most often paraboloidal, which significantly reduces divergence of emitted light. Further reduction of light divergence is achieved by placing an appropriately shaped dioptre in front of the reflector. This combination of cluster, reflector and dioptre creates a new type of lamp based on the light-emitting diode - a light-emitting diode cluster-lamp, known as the "Cluster LED Lamp". The invention uses this cluster-lamp as a source of light for photodynamic diagnostics because it is an inexpensive, compact, light and effective light source. The invention utilizes those wave lengths emitted by the cluster which are found around the absorption maximum of the appropriate photo-sensitizer, and which provoke it to fluorescence.
