If any of you guys could help me out, or point me in the right direction, it would be a great help!
Thank you in advance!

What is the context of the question? What are your thoughts on it so far? What factors go into the efficiency of an LED, from electrical energy to the final light energy that makes it out into the air?
greynoon said:My thoughts so far are: It has something to do with total internal reflection or snells law!
http://en.wikipedia.org/wiki/LED#Light_extraction"Substrates that are transparent to the emitted wavelength, and backed by a reflective layer, and light spreading layer, increase the LED efficiency. The refractive index of the package material should match the index of the semiconductor, otherwise the produced light gets partially reflected back into the semiconductor, where it may be absorbed and turned into additional heat, thus lowering the efficiency.
The main difference between square and triangular LEDs is their shape. Square LEDs have a square shape, while triangular LEDs have a triangular shape. Additionally, square LEDs tend to have a larger light emitting area, while triangular LEDs have a more focused beam of light.
Square LEDs have a larger light emitting area, which means they can produce a brighter light and cover a larger area. They also have a more uniform distribution of light, making them ideal for applications where even lighting is important, such as in displays or signage.
No, square and triangular LEDs are not interchangeable. The shape of the LED affects the direction and distribution of the light it emits. Therefore, they are designed for different purposes and cannot be used interchangeably.
Yes, both square and triangular LEDs can be used for outdoor lighting. However, square LEDs are more commonly used for outdoor lighting as they have a larger light emitting area and can produce a brighter light, making them more suitable for outdoor applications.
One limitation of conventional square and triangular LEDs is their relatively low efficiency compared to other types of LEDs. This means they may consume more energy and may not be as cost-effective in the long run. Additionally, their shape limits the direction and distribution of light, so they may not be suitable for all lighting applications.
