coconut

The coconut palm is grown throughout the tropical world, for decoration as well as for its many cooking and non-culinary uses, virtually every part of the coconut palm has some human use.The flowers of the coconut palm are polygamomonoecious, with both male and female flowers in the similar inflorescence. Flowering occurs continuously, with female plants producing seeds. Coconut palms are believed to be largely cross-pollinated, although some dwarf varieties are self-pollinating. Coconut water can be used as an intravenous fluid.
Nearly all parts of the coconut palm are useful, and the palms have a comparatively high yield, it therefore has important economic value. The name for the coconut palm in Sanskrit is kalpa vriksha, which translates as the tree which provides all the requirements of life. In Malay, the coconut is known as pokok seribu guna, the tree of a thousand uses. In the Philippines, the coconut is generally given the title Tree of Life. The white, fleshy part of the seed is safe to eat and used fresh or dried in cooking.

LED

A light-emitting diode (LED) is a semiconductor device that emits incoherent narrow-spectrum light when electrically prejudiced in the forward direction of the p-n junction. This effect is a structure of electroluminescence. An LED is usually a small area source, often with extra optics added to the chip that shapes its energy pattern. The color of the emitted light depends on the composition and situation of the semi conducting material used, and can be infrared, noticeable, or near-ultraviolet.
LEDs produce more light per watt than do luminous bulbs; this is useful in battery powered or energy-saving devices. It can emit light of an proposed color without the use of color filters that traditional lighting methods require. This is more proficient and can lower initial costs. The solid put together of an LED can be designed to focus its light. Incandescent and fluorescent sources often need an external reflector to collect light and direct it in a usable manner. When used in applications where dimming is required, LEDs do not change their color tint as the current transient through them is lowered, unlike incandescent lamps, which turn yellow. They are ideal for use in applications that are subject to common on-off cycling, unlike fluorescent lamps that burn out more rapidly when cycled frequently, or HID lamps that require a long time before restarting.
