Pros and Cons of LED Sign Board
The world of LED Lighting, LED Screen & LED Sign Board can be very confusing for the general public to get there head around. To a large extent because many industries use different terminology and standards.
In this blog we attempt to discuss the pro & cons and point out some of the similarities and some of the differences.
LED lights are solid-state sources of light, and therefore, they normally have a very long lifespans and are generally very robust. Older style Incandescent lights, in general had a very much shorter lifespans of anything even as low as 1000 hours. LED lightbulbs used in today’s LED Board and LED Screen are able totake this lifespan out to more than 100,000 hours at 50% brightness, which is greater than ten years.
In reality, this estimate can be a bit misleading. Like any other source of light, an LED light’s performance degrades over time. The level of degradation is directly proportional to many different factors such as operating temperature and current.
Presently, LEDs do not come with a defined lifespan, although different parties suggest different lifespans. What is excepted is that the light output of good quality LEDs’ will deteriorate by 3 -5% a year with constant use.
Even today, LED light bulbs lack general standardization. Various industries use their own standards for LED lights. For instance, the automobile industry uses a different standard of LED lighting for its automotive lighting equipment. At the same time, traffic signals require a specific kind of LED light for general use. Different bodies are still conducting their research to derive a standard for use across all industries.
- Low maintenance
LED light bulbs require very limited maintenance, and as we have discussed above offer a superior lifespan in comparison to any other type of light source. That is why the LEDs once correctly installed do not require frequent replacement. This feature greatly reduces the overall life cost of the LED Screen or LED SignBoard. The capital required to stock large inventories of spares is significantly reduced. They are robust and highly efficient in comparison to all other types of light sources. It is for these reasons why LEDis the only choice in our modern world.
LED bulbs are highly efficient sources of light. White LED bulbs produce an efficacy of 25lm/W, far outpacing the output of fluorescent and incandescent light bulbs. The kind of light generated by the LED bulbs is directional, which helps the manufacturers design the LED bulb with higher luminance’s and better overall efficiency.
- Lower power consumption
LED bulbs consume very little power. As a result, you will experience significant savings in energy when you install LED-based lighting solutions in all situations and in particular LED signboard. And LED Screen. Often clients who may have had a static signage installation with tradition flood lightning can replace these old signage technologies with a new self-illuminating LED Sign Board, and notice very little difference to their energy costs.
Although LED light bulbs are highly efficient and consume very little energy, the LED devices generally produce a smaller quantity of total lumens. For instance, in lighting a 60-watt incandescent light bulb with an efficiency of approx. 20lm/W generates about 1200 lumens. The one-watt LED that has an efficiency of about 30lm/W generates only 30 lumens. In simple terms, one needs 40 LED bulbs to get the same brightness as produced by one incandescent light bulb.
LED light bulbs produce very little heat or any infrared radiation. Therefore, the LED light bulb does not become as hot as an incandescent light bulb would. The total absence of infrared radiation allows the LED bulbs to be fixed in various locations where conventional light sources could cause serious problems, such as while illuminating textiles and food.
Without proper heat sinking and thermal management, the LED s junction temperature rises, this can cause a reduced lifespan. Driving the LEDs above there rated current input causes the temperature of the junction to the PCB to increase to higher temperature levels where you would likely experience permanent damage to the LED failure.
In the modern world of mass production, the cost of LED’s has come down considerably making them the clear winner in virtually every area. They are perfectly suited to be incorporated into a LED signboard, and higher resolution LED Screen. They are inexpensive to mass produce, very reliable and offer very low whole of life costs. LED manufacturers are always working on ways to reduce their production costs and this has been very evident over the past 5 years or so with much higher resolution screens becoming more affordable, as an example.
We have attempted in this blog to layout the advantages of LED technology by discussing the benefits as well as the drawbacks of the technology for industrial or commercial use. LED’s are the most sustainable solution to produce highly efficient light and to save energy.
