LED Lighting BASIC PHYSICS:
a) Give typical forward I-V curves for R-G-B LEDS. Be specificin your three explanations and use manufacturers spec sheets. Alsoexplain why LED lights are both Hg (think bulb breakage effects andland fill issues with dead fluorescent bulbs) and UV free ascompared to fluorescents. UV rays cause colors to fade in retailclothing stores, art work to fade in museum lighting and UVaccelerates the rancidity of meat fat. UV accelerates the rancidityof meat fat.
b) Explain how and why LED emission takes place over a smallsolid angle or in simple terms in beam like and unidirectional. Usemanufacturer spec sheet plots of emission angles. In contrastfluorescent and incandescent light is omni-directional spreadevenly over all 4Ï€ sterradians.
