Really diverse size color and shapes of LEDs Reasonable price costs saving from polymer materials so LEDs are durable easy to transport without the fear of breakage LEDs generates more light and have a lifespan up to 70 thousand hours of use if a LED lamp has 8 hours lighting a day after 23 years it need replacing saving power up to 70 80 in comparison with conventional lamps Insignificant thermal energy generated during operation Works well in low temperature conditions Use direct current with small voltage Environmental friendly because LEDs do not generate ultraviolet rays or mercury Applications LEDs are used in many fields in our life such as decorating reading lighting advertising Especially outdoor advertising in the toughest places for fitting or replacing lights because we can take advantage of its many times longer lifespan than Neon lights Moreover they are various in colors red green blue amber We will use super bright LEDs commonly used as billboards with low power consumption high reliability and good performance in this project 1 2 2 The Idea Our idea 1s to combine multiple LEDs to create many different effects served in the outdoor advertising or indoor decoration as a prominent furniture in the room We use multiple LEDs connected together in a cube to create the 3D effect by turning off the lights automatically at various locations thro
