is led lighting ready for the mass market?
Although it is developing rapidly, it is still a relatively new technology that will take a while to build itself.
Are the consumers of LED ready?
Since its first development in 1927, LED technology has undergone many changes, most of which have occurred in the past five years.
This is mainly due to changes in legislation worldwide to stop the production of incandescent lamps, as well as consumers who have not been given their CFL (
You may think that the argument to convert to LED is persuasive;
With the rapid rise in energy prices, LED lighting uses about 80% less energy than incandescent lamps, and with the use of intelligent lighting control systems, these savings can be further increased.
In addition, LED manufacturers claim that most LEDs have a life span of 30 years, or 5-compared to 6 to 12 months of conventional bulbs-
10 years of CFL
In addition, led does not contain toxic mercury, unlike CFLs.
Therefore, during the service life of the products, they are much cheaper than other light sources, and environmental protection: With their duration, landfill sites will be reduced and no harmful chemicals can be disposed, and can save energy.
So while more and more people are moving from traditional to LED, why not everyone?
The main reason consumers delay investing in LED is the initial high cost until this cost drops, which will be in the process of this fast
Mobile market, even with long term knowledge, many people will not be persuaded to switch
Long term cost savings.
Put your hands in your pocket and hand over £ 30 for an LED bulb is a lot harder than buying a traditional bulb for £ 1.
The CFLs are not quite like 10 years ago, with the launch of the compact fluorescent bulb, the last major change in the lighting space.
These are sold with their energy.
Save benefits and can be purchased between 2 and 10.
Many people have made changes but are not happy with the product: they don\'t like the slow start --
At the time, the color output is poor, the bulb looks ugly and there is a problem with dimming.
This makes the public cautious about another new product.
Changes in LED technology all major lighting manufacturers are investing in research and development of LED technology, trying to improve the product while expanding the product range.
This means that the product changes every few months, and there are more and more demands on the life and efficiency of the led, which makes the market very chaotic.
When the same manufacturer replaces the new LED bulb with a \"better\" model within 4 months of release, how can consumers buy it confidently?
One of the main problems of how to compare different light sources is the lack of standard test procedures between products, so it is very difficult to compare incandescent lamps, compact fluorescent bulbs and LED bulbs.
If consumers want to replace their traditional bulbs with LED, they want to get similar or better light output, but it is difficult to compare power and lumen output.
In fact, viewing the lumens per watt may be the best way to compare, but there are also problems with it: directing other technologies to project light into multiple directions, whereas LEDs are one-way, more like
Therefore, when comparing lumens, you are comparing the light that travels through a larger angle (
Light moves in one direction (LEDs).
Therefore, the direct lumen comparison does not accurately reflect the amount of light reaching the surface of the application.
This means that in the case where a directional beam is required, the LED will usually do a good job, but in the case of replacing incandescent lamps that need to expand the light, the LED will look much darker.
Before the LED bulb usually has a larger beam angle, for example, when it is 120 ° compared to standard 38, the quality of the light will not be the same.
Rendering color index (CRI)
CRI is the effect of measuring the color of the bulb rendering, and the measurement of 100 is the most complete.
The CRI of incandescent lamps is 100, but the average of LEDs is still around 85 degrees.
The light will still not look so good until this improves.
In the current future, the initial cost of expenditure is too high, the technology changes too fast, and the quality of light output at a reasonable cost has not yet been achieved.
However, with all the money the manufacturer has invested in R & D, the LED bulbs will one day be ready for the mass market, just not ready yet.
