LED’s proprietary characteristics above mentioned determines their ideal suitability in a wide range of application.
Decorative lighting Due to the rich variety in colors, small size, durability, energy savings, LEDs are perfect light source for decorative application. Attached on a PCB, flexible cable, or other desired materials; LEDs can be used for light source of [...]
While LED (light-emitting diode) costs are still high, this type of lighting is extremely long-lasting. And as prices come down, its efficiency could lead to huge energy savings.
The first consumer LED products lit up in the 1970s, with red light numbers on pocket calculators and push-button displays on big, geeky Pulsar watches. Then came those [...]
Foreword AC responses of LED drivers are critical but usually ignored in LED display applications. AC responses affect the major performance of LED display panels, such as grayscales, linearity, EMI, and reliability. Although there is trade-off within these requirements, LED drivers can provide balance. This article will further explain the importance of the AC responses [...]
Common infrared LED that emits infrared rays has the same appearance with visible light LED. Its appropriate operating voltage is around 1.4v and the current is generally smaller than 20mA. Current limiting resistances are usually connected in series in the infrared LED circuits to adjust the voltages, helping the LEDs to be adapted to different [...]
Nowadays, LED products are being used in numeric displays and indicator lights to a range of new and potential new applications, including exit signs, accent lights, task lights, traffic lights, signage, cove lighting, wall sconces, outdoor lighting and downlighting.
The following is the list of LED applications:
• Streetlights • Large scale video displays • Architectural lighting [...]
Conserving energy is now a mandate, not a choice, and part of that mandate is the need to go Green. When it comes to lighting, we can easily imagine the impact of globally improving the efficiency of lighting sources by 10 percent. But what if it could be improved by 1,000 percent? Newly enhanced LEDs [...]
LED is made up of a very small chip packaged in the epoxy resin. Generally, the operating voltage is 2-3.6V and the operating current is 0.02-0.03A. Traditional incandescent lamp emits light depending on tungsten filament, and the power-saving lamp depends on tricolor powder. Different from these two kinds of lamps, LED emits light through electric [...]
What is an LED printer? LED printer was firstly invented by the Okidata co. in Japan and has been put into use for a period of time. Currently, it is developed and manufactured mostly by Japanese companies. The cost of LED printer is lower than laser printer, which scans the information onto the rotating drum [...]
Unlike conventional incandescent lamps which need to convert the electricity into thermal energy first and then to light, LED illumination is achieved when a semiconductor crystal is activated so that it directly produces visible light in a desired wavelength range. With the continuous development of lighting technologies, more possible future applications of LEDs will be [...]
An introduction to Solid State Lighting
Solid-state lighting (SSL) is the new lighting technology to emerge for many years: it uses semi-conducting materials to convert electricity into light. The term “solid state” refers to the fact that light in an LED is emitted from a solid object (a block of semiconductor) rather than from a vacuum [...]
