… technologies indifferent applications. How does the different technologies for light generationwork and what are the advantages and disadvantages? The various technologieslimitations and characteristics provides the opportunities for the LEDs.This report describes a …
… The purpose of the thesis was to make a research if it is possible to produce light emitting weaves with optical fibres in an industrial production. The thesis was divided into several parts, both theoretical and practical. The theoretical part involved taking part of different …
Evaluation and clarification of the new Organic Light Emitting Display technology
Organic Light Emitting Displays (OLEDs) are a new type of thin emissive displays predicted to possess superior properties to existing techniques e.g. Liquid Crystal Display (LCD). The main advantages are low power consumption and a thin display structure. This report contains an …
… A turnable reflector couldn’t be combined with the isolation. The suggested light emitting diodes wouldn’t give enough light, so I cut them out and the problem with light remains to be solved. The old grating had many rods and I changed that to a grating with fewer rods to make …
… design of a headlamp with a cluster of three or possibly four high power LEDs (Light Emitting Diodes). During the work, two different problems have been considered; how to design a lens in order to shape the light beam in a desirable way, and how to design a cooling system which …
… objects from their backgrounds. A dark object is discernible from a lighter background using the OFFpathway and the ON-pathway is used to descry a light object upon a darker background. This study shows that the dog ERG has both ON- and OFF-responses and that these responses can …
The Lovebomb
… confirm message the LoveBomb conveys this to the user by turning on a red LED (light emitting diode) and letting the LED shine for about half a minute. During this time the LoveBomb can only receive messages. If it receives a message, during these 30 seconds, the LED is turned …
