NEW DELHI: You must have heard the terms LED and OLED. Do you know the difference between the two?
OLED is an organic light emitting diode whereas LED is a light emitting diode in which emissive electroluminescent layer is the film of the organic compound, which emits light in response to the electric current.
Organic LED lighting has many benefits. Few of them are given below:Lifespan of OLED lights is more
They last 2 to 4 times as long as most florescent, metal halide and even sodium vapor lights. The LED lights have low maintenance costs in terms of labor and the lower costs for the replacement parts. OLEDs are Energy EfficientOLEDs usually consume low amounts of power. The statistics to look for whenever comparing the energy efficiency of various lighting solutions are called by one of the two terms: useful lumens and luminous efficacy. These two items describe the amount of light emitted per unit of power consumed by the bulbs.
Most of the LED lighting retrofit projects result in 60 % to 75 % improvement in overall energy efficiency of the facility lighting. Based on the existing lights and particular LEDs installed, the savings can be more than 90 %.
OLEDs are safe
Safety is often overlooked advantage whenever it comes to LED lighting. The first hazard whenever it comes to lighting is emission of heat. LEDs emit no forward heat while the traditional bulbs convert more than 90% of the total energy used to power them directly into heat.
OLEDs are physically small
The actual LED device is very small. Various uses of OLEDs include a wide spectrum from their roots in circuit board lighting and the traffic signals to modern mood lighting, commercial and residential property applications and major stadium lighting.
OLEDs have great color rendering index (CRI)
CRI is the measurement of the lights ability of revealing the actual color of the objects compared to the ideal light source i.e. natural light. High CRI is a desirable characteristic. LEDs usually have poor CRI ratings whenever it comes to CRI.
Hence the best way of appreciating CRI is to look at the direct comparison between LED lighting and traditional lighting solutions like the sodium vapor lamps.
