A projective LED dental lamp designChung, Yu-Lin 17 August 2011 (has links)
Halogen lamps are mostly applied as a light source to the traditional lamp for medical treatment due to its proper color temperature, but it has its disadvantages such as ultraviolet rays and infrared rays which will be harmful to the patients and faculties in the hospitals under long-term exposure. Consequently, using light emitting diode(LED) as a new light source instead of the traditional halogen lamp will be the trend of the future. The purpose of this study is to design a projective LED dental lamp that can achieve the goals of 200mm¡Ñ100mm for light shape and 11000lux illuminance energy by using the optics simulation software, LightTools. Firstly, a single LED lamp module with a high focusing hollow tubular light guide structure was designed and developed comparing with the solid light guide structure used in many commercial projective dental lamp, the hollow tubular light guide structure can decrease illuminance energy lose due to the absorption by tube material. Because the required objective light shape could not be achieved by using the designed light guide structure only, so a lens component was adopted and designed in order to shrink the output light shape to the required size. Finally, through the specific arrangement of position and angle of each LED lamp module, a projective LED dental lamp with 9 LEDs lamp modules which conform with the required illuminance energy was proposed.

Campos de luz: contaminações luminosas no Teatro Paulistano 2011-2012 / -Ochoa, Manoel João 14 December 2012 (has links)
Este trabalho pesquisa as aplicações da iluminação cênica em alguns coletivos teatrais paulistanos no período de 2011-2012, para entender a prática do desenho da luz, constatando a utilização ou não de novos equipamentos e técnicas. Para isso, fez-se o estudo de peças produzidas e apresentadas no período mencionado, e entrevistas com iluminadores, diretores e outros profissionais da cena ligados a grupos filiados à Cooperativa Paulista de Teatro e contemplados com o Programa de Fomento ao Teatro da Cidade de São Paulo. Outra preocupação deste trabalho foi a análise da formação dos profissionais de iluminação desses coletivos. / This work researches the aplication of Lighting designer in Drama groups from São Paulo between 2011 and 2012, for understand the pratice of light shape and the using of modern equipments and technics. Therefore, a study was made about plays produced and presented in the mentioned period, and interviews with lighting designers, directors and other professionals in the area related of groups affiliate with the São Paulo Drama Company e benefit from the Program of Promotion of the Theater in the city of São Paulo. Another of this work was a analysis of the formation of the Light Designers of this groups.
