In 2020, LEDs are estimated to achieve a 61 percent penetration of the global lighting market. As Asian countries are likely to increase their share in global sapphire production, thus eroding the price of semiconductors, the cost of LED lamps is expected to decrease rapidly. Currently, LED lighting is predominantly used as a backlight technology for television and mobile phone screens. As of 2015, the lighting segment dominated the overall LED market worldwide. LEDs are applicable to many different uses due to its compact size, resistance to breakage, and ability to focus light in one direction. Its ability to focus in one direction reduces the need for reflectors and other diffusers that trap light, making it useful for various purposes such as task lighting.
