LED : Advantages

Features and Benefits of LED

The inherent features of LED is decided on the ability of LED to become the best alternative to conventional light sources, and provide a wider range of applications.

Small Size

An LED is essentially a microscopic chip once encapsulated in an epoxy resin are extremely small and light weight.

Lower power consumption

LED consume very little power, far less than standard light bulbs leading to greatly reduce energy costs and extremely enhanced global energy savings. LED also requires far less energy to manufacture than other light sources, reducing the environment impact of artificial lighting even further. Generally a LED is designed to operate at 2-3.6V, 0.02-0.03A current which means LED typically requires no more than 0.1W to operate.

Rugged

LEDs are rugged, solid state devices and are not susceptible to vibration such as with incandescent filament based bulbs.

Long Lifetime

When operating at specified voltage, current and within specified environment conditions, LED can enjoy a long life of up to 100,000 hours. A newer way to evaluate LED lifetime has been established which is based on lumens depreciation over time to determine the mean time between failure.

High lumen efficiency and low heat emitting

Due to the special materials that are used to manufacture LEDs during electrons transition, LEDs mainly emit electromagnetic energy in the visible part of spectrum. This is unlike incandescent filaments which are heated and emits large amount of electromagnetic energy in the infrared spectrum which canít be seen and felt as heat. That is to say, LED can convert significantly more of the energy applied into light and therefore LEDs have higher luminous efficiency with substantially lower amounts of heat produced.

Environment Protection

LEDs are made from non-toxic materials, unlike fluorescent lights that contain mercury which poses a danger to the environment and human health. LEDs are recyclable.

Unbreakable

The LED semi-conductor chip is embedded in an epoxy resin enclosure which is much sturdier than traditional glass bulbs and fluorescent tubes. They are solid state technology thus no loose and moving parts which makes LEDs virtually indestructible.



The Application of LED

LEDs proprietary characteristics mentioned above determine their ideal suitability to be applied in a wide range of products and applications.

Decorative Lighting

Due to the rich variety in colors, compact size, durability, energy savings and long life, LEDs are a perfect light source for decorative application. Mounted on a PCB, flexible PCB, cable wire or other electrically conductive materials LEDs are versatile and are being applied to the entire range of decorative lighting.

General and Commercial illumination

With the advance of LED technology applied singularly, in clusters or arrays are now bright enough to be used for general and commercial illumination. Homes, offices, public buildings, shopping centers and alike all around the world are applying LED based illumination products.

Displays

Indoor and outdoor display systems are rapidly becoming the mainstay of the display and signage industry. The affordability of LED based screens and displays are also rapidly becoming cost effective through variety of designs, resolutions and varied pixel pitch.

Color

The advancement of LED technology and color control systems have brought about a very broad spectrum of single, mixed RG, RB, GB, AWB, RGB, RGBY, cool white, warm white and ultra warm white. Varied combinations, applied with various mixtures of phosphors have brought about true rainbow of available colors.

Intensity, Beam Angle and viewing angle

LED light output varies with the type of chip, encapsulation process as well as other variables. Generally the amount of light emitted from a LED is quantified by a single point, on-axis luminous intensity value and is specified in milli-candela (MCD) A LED with luminous intensity value does not mean that it has higher total light output. To measure the total light output, the viewing angle must be taken into account too. LED viewing angle is also a function of LED chip type and epoxy lens that distributes the light. LED with different chips and epoxy lens will have different viewing angles. If two LEDs have same luminous intensity value, the lamp with the larger viewing angle will have the higher total light output.
