The advantages and disadvantages of LED floor lighting

The advantages and disadvantages of LED floor lightingCharacteristics of LED street lamp, semiconductor lighting, lamps, light emitting diodes as a light source, because it is a solid cold light source, environmentally friendly non-polluting, low power consumption, led high bay, high luminous efficiency, long life, made of LED lights.
Advantages:
1, LED street light its own characteristics – light one-way, led floor lighting, there is no diffusion of light to ensure that light efficiency.
LED street lamp has a unique optical design, LED street light shines on the required area lighting, led floor lighting, and further improve the light efficiency, in order to save energy.
3, the efficiency of the LED light source and currently has 110-130lm / W, but there is still much room for development, the theoretical value of 250lm / W. The luminous efficiency of high pressure sodium lamp with the power increase only increase the overall light efficiency LED lights than high pressure sodium;
4, the light color of the LED lights than high pressure sodium high many, high pressure sodium lamp color rendering index is only 23 or so, led floor lighting, while the LED street lamp color rendering index to reach 75 above, from the perspective of visual psychology to consider, to achieve the same brightness, LED lights light degrees average can more than 20% lower than the high pressure sodium.
5, LED street light a small decline, the light fades less than 3% a year, for 10 years to reach the road using the illumination requirements, high pressure sodium lights and feeble, led floor lighting, has fallen more than 30 percent a year or so, LED lights on the design of the use of power can be low than high pressure sodium lamp.
6, LED small piece of each unit is only a small volume, so the device can be fabricated into various shapes, and is suitable for variable environment.
7, long life: 50,000 hours or more, a three-year quality assurance. Inadequacies in the life of the power supply is not guaranteed.
Disadvantages:
A. Single LED low power.
In order to obtain high-power, more used in parallel.
Two. Low color rendering index.
Color LED irradiation is not true incandescent, from the spectral distribution up analysis, a technical problem.
3. Spot.
Since the white LED manufacturing defects in workmanship coupled with the errors of the reflector or lens, led floor lighting, likely to cause a yellow circle.
4. LED irradiation uniformity
If you do not second optical design, LED exposure is more concentrated, so be sure to conduct a second optical design so that it was the bat-shaped light intensity distribution of mini-integrated LED street map.
