Reasons for Rising Popularity of LED Lights

LED or Light Emitting Diodes are a type of solid state lighting which is highly durable and efficient. While incandescent and fluorescent lights feature gases filled in bulbs or filaments kept in glass bulbs, LEDs consist of lenses or small capsules in which are placed tiny chips on materials that conduct heat.

LEDs are playing a major role in ensuring that places and people enjoy efficient, clean and affordable light. Incredible innovations for industrial as well as residential applications are underway. The future trend of residential lighting is the pervasive adoption and utilization of LED light bulbs. LED is growing popular as lights in residential lighting fixtures as well as commercial and industrial use.

While present market for white LED lights is serving mainly early adopters and enthusiasts, the cost-effectiveness and efficiency of LED lights will drive future demand for LED lighting that is affordable. This bodes for the exciting area of opto-electronics and experts predict that in the near future, LED lights will become cheap and powerful to replace all incandescent light in offices, homes, outdoor signs and street lights.

Here are a few reasons for growing popularity of LED lights:

Efficiency and Size

The general LED lights measure from 3 to 8mm long and maybe used singly or in form of an array. The low profile and small size of LEDs permit them to be used in spaces which are too small for other light bulbs. Also, because LEDs emit light in a specific direction, they are more efficient in use than fluorescent and incandescent bulbs that waste energy by spreading light in all directions.

Long Life

The operation life of current white LED lamps is 100,000 hours. This implies 11 years of continuous operation or 22 years of 50% operation. The particularly long life of LED’s is in sharp contrast to average life of an incandescent bulb, which is around 5000 hours. In case, lighting needs to be set up in a very inaccessible spot, LED’s are the best option thanks to their durability and avoiding need of changing bulbs frequently.

Cost Factor

There is no comparison between cost of LED’s and traditional incandescent bulbs. With regard to incandescent bulbs, the true cost of bulbs is that of replacing bulbs and the time and expense of labour involved in replacing them. These are substantial factors, particularly where there are a large number of bulbs to be installed. Such issues can be totally avoided with LED lights.

Energy Efficiency

The main strength of LED technology is the lowered consumption of power. When made in a good design, an LED system will offer 80% efficiency which amounts to the fact that around 80% of electrical energy will be converted to light energy. Only 20% is lost as heat energy. Compare this to fluorescent lights which only have 20% efficacy (80% is lost as heat).

Low Temperature

LEDs remain cool when compared to incandescent and fluorescents. Incandescent wastes 90% energy as heat while fluorescents do it for 80%. Also, LEDs do not have any glass components and so they are not prone to breakage or vibrations like conventional bulbs.

Recycling

Traditional lighting sources use chemicals like mercury but LEDs use safe materials like Phosphor, without leaving a carbon footprint in ecological terms. Also, LEDs can be easily recycled.

These are all some reasons for rising popularity of LEDs.
