Utilization of light emitting diode lighting
Podola, David ; Černý, Michal (referee) ; Paloušek, David (advisor)
This bachelor thesis deals with problems of illumination by LED diodes. Basic concepts of lighting technology are defined in the first part. The second part is dealing with the construction of body LED diodes and explains the principle of white light formation to LED. Introduces problems of cooling. Gives an overview of the available power sources for LEDs. Provides an overview of how to control lighting by using motion sensors and presence sensors. Will be made basic economic balance sheet, which will evaluate the advantages of using LED sources. Attachments provide the LED catalogs of manufacturers, accessories for LED and comment on other sources of information.

Photometry and spectroradiometry of LEDs
Vysoudil, Martin ; Škoda, Jan (referee) ; Drápela, Jiří (advisor)
This thesis deals with the processing of light technical parameters and performance of key LED chips for their applications in lighting systems. The aim is to create a laboratory model for measuring the qualitative and quantitative parameters of highly luminous light LED emitted depending on the angle, using a spherical integrator 0.3 m, goniometer and fiber spektroradiometr /luxmeters. Goniometer is designed using modular optomechanical parts company Thorlabs. Due to the current passing through the LED chips heat up considerably. To light LED chip parameters tested were not affected by heat from the chip is required to pay the heat generated by a passive radiator. Another part of this thesis is the reconstruction of an older model spherical integrator. Reconstruction must be undertaken so as to ensure sufficient cooling again tested LEDs. Light scattered in the ball of the integrator is led by the optical cable to the spektroradiometr that are subsequently recorded its parameters. The second element used to measure the light produced by the LED source is photocell. Spherical integrator must be appropriately modified to indicate the two measuring elements and also meet the standards of determining the correctness of measurement. At the end of the measurement results will be compared with catalog values provided by the manufacturer.

A light source with ligh emmiting diode
Novák, Matyáš ; Mojrová, Barbora (referee) ; Boušek, Jaroslav (advisor)
This work starts with the basic description of function of light-emitting diode. It also describes the basic techniques of design of cooling housings for power LEDs and possibility of heat removal. In the theoretical part of this work is also described the possibility of heat dissipation regulating and the possibility of the power sources for LEDs. The practical part includes description of LED light source design and construction, using knowledge about cooling and power from theoretical part. The light source is designed for different kinds of power supplies for maximum flexibility of usage.
