LEDs proprietary characteristics mentioned above determines their ideal suitability to be applied in a wide range of products and applications.
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 the WLED (White 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 new WLED based illumination products.
Indoor and Outdoor Visual 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 more cost effective through a variety of designs, resolutions, and varied pixel pitch.
Because of LEDs compact size, durability, energy savings, long life, and low power consumption, LEDs are perfect light sources for LCD backlight displays.
The advancement of LED technology and color control systems have brought about a very broad spectrum of single, mixed RG, RB, GB, AWB (Amber White Blue) RGB, RGBY, Cool White, Warm White, and Ultra-Warm White. Varied combinations of varied blue wavelengths, blue green combinations, applied with various mixtures of phosphors have brought about a 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 (LV), and is specified in milli-candela (MCD). A LED with higher 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 the LED chip type and the epoxy lens that distributes the light. LEDs with different chips and epoxy lens will have different viewing angles. lf two LEDs have the same luminous intensity value, the lamp with
the larger viewing angle will have the higher total light output.
