Today's building structure allows us to marvel at its intricacies and provide us with the technology we need for comfort. The development of emergency lighting further demonstrates how buildings can be digitally transformed to achieve cleaner, smarter cities.
Emergency lighting professionals point out that “lighting is the ideal coordinator of smart technology; it is fixed, has a constant power supply, and can be easily installed without causing interference to building occupants.”
Thanks to the software and services used to store, process and analyze the collected sensor data, the lighting itself will become more technologically advanced, which will help transform emergency lighting into its current state and continue to help future industry innovations.
“As the demand for smart devices increases, including lighting, the cost base will fall, and the market will reach the critical point of wholesale adoption. At this point, the promise of the new industrial revolution will really happen.” - Emergency lighting professionals
In any emergency lighting study, there is often a debate about the type of lamp that can be effectively executed. Some people like fluorescent lights, and some people prefer LED lighting. Recently, however, many have concluded that the latter provide better services than conventional fluorescence.
Emergency Light Manufacturers will show you why LED technology takes precedence over fluorescent technology in emergency lighting. We will also show you the benefits of using LEDs for emergency lighting.
Clear comparison between LED and fluorescence technology
Unless you have a career in the lighting industry, managing the differences between LED lighting and fluorescent light types can be difficult. This similarity exists because both bulbs have a familiar physical appearance. However, there is a significant difference between these two types of light.
LED and fluorescence: longer duration?
All luminaires have an expected life. This is the time required before the failure, and its value is in hours. For T5 fluorescent lamps under constant lighting conditions, the lifetime may be 15,000-30000 hours, equivalent to 1.7 to 3.4 years.
Or, LED luminaires have the advantage of being longer running. These lights can work between 50,000 and 100,000 hours, which is 5.7 or 11. 4 years, uninterrupted use. In short, the life of LEDs is more impressive than fluorescent tubes.
In addition, T5 fluorescence technology uses electronic ballasts that are different from previous fluorescence techniques using traditional mechanical ballasts. On the other hand, LED technology uses new components in the form of LED drivers.
However, different levels of quality of the LED driver and electronic ballast may result in additional components having an indeterminate life expectancy, resulting in complete replacement of the luminaire. Therefore, users should consider the quality and service life of the product when looking for suitable lighting technology.
LED or fluorescent: Cost?
LEDs should be used as a relevant option when selecting economical emergency lighting. It is a factor worth choosing; it lasts longer than ordinary fluorescent technology. In terms of emergency lighting, the cost of the product must be considered. In this case, not only the cost of the purchase but also the annual functional cost should be considered. The price of LED lamps for commercial purposes has risen. However, the lower operating cost and long life characteristics make fluorescence less favorable.
LEDs are more effective than fluorescent bulbs
Studies have shown that LED lamps are more efficient than fluorescent lamps. The results of the energy saving study show that the LED is more efficient because there is no loss in the side of the lamp. In addition, LED lamps consume less power and last longer than other types.
Another study on the use of 6-watt LED lamps for about 5.93 hours showed an energy savings of about 66.12%. These lamps replace the use of 13-watt compact fluorescent lamps.
Directional light source
Unlike the 360-degree pattern associated with fluorescent lamps, LED bulbs are illuminated in a 110 degree manner. However, for tubular fluorescent illumination, only a small fraction (about 30%) of the light is illuminated to the intended target. This means that we don't use all the light from the fluorescent bulbs because they also brighten the fixture.
Unlike a fluorescent bulb that "burns out" or dies over time, the LED light maintains its brightness for a longer period of time. This is because lumens are attenuated, that is, the light intensity of the LED is slowly dimmed.
LED lighting products emit light through their energy. On the other hand, fluorescent lamps use heat to generate light, making it unpopular with homeowners.
the effect on the environment
We can see another difference in the presence of mercury in fluorescent bulbs. According to Aucott et al. (2003), a discarded fluorescent bulb emits a large amount of toxic mercury gas when it is broken. This operation can pollute the environment. However, LED lights do not contain glass or mercury, making them a safer alternative to lightning.
LED lights match natural sunlight. This similarity occurs because the LED chip contains a representation of all colors that display the brightest white. It also emits every color like the sun. However, fluorescence has a small rendering due to the sharpness of the wavelength of its particular color and cannot mimic sunlight.
Benefits of using LED technology for emergency lighting
Due to the advantages of the aforementioned tubular LED illumination, the problem of the benefits of LEDs as an ideal source of emergency illumination should be considered.
LED lights almost meet the standards of each photometric parameter. The end of life of LED lighting is an advantage, while at the same time having the amazing ability to save energy. In addition, LEDs are popular with designers and architects for their associated with more efficient implementations of emergency lights.
Now let's take a closer look at how LEDs achieve emergency lightning and it's the best choice for installers and users.
Cheaper long-term costs
Compared to other light sources, LEDs seem to be at a disadvantage due to installation costs. However, LEDs have a higher advantage when considering the entire life cost. For example, comparing a conventional 8W maintenance independent bulkhead with an identical watt LED, the cost comparison ratio is 1:2 or 1:4, respectively.
A rigorous review of the cost of replacing two light sources and batteries within eight years also makes LED a suitable alternative. During this time, both sources need to be replaced; however, the 8W fluorescent bulkhead needs to be replaced several times. This requirement burns a hole in the user's pocket because the change in each lamp equals the initial cost of the expensive labor and the cost of the bulkhead.
Making safety a top priority
Emergency lighting is required for locations with so many infrastructures, such as underground parking lots, around buildings or within buildings. Emergency lights can move quickly and safely during difficult times such as fires. Thus, the presence of a suitable exit light sign is indicative of an exit route that prevents panic.
Recently, LED modules that can replace fluorescent lamps have become popular with installers and users. These lamps are low cost and highly efficient, making them a sought after product in the emergency lighting industry.
Since LED systems have so many positive properties, this technology has the potential to be an ideal source of light. Because it does not contain environmental toxins such as lead or mercury, LED lights do not have any negative impact on the environment. In addition, its non-volatility makes it a valuable material in environments considered to be explosive. Mines and oil rigs.
Due to their energy efficiency, LED luminaires can operate on backup batteries or generators that start up in the event of a power failure. The LED light acts as a point source so it is easy to direct it where it is needed. This feature, combined with its high optical efficiency, increases its energy efficiency.
LED-based emergency lights also have an advantage in terms of energy consumption. LED lamps consume only a fraction of the energy required for fluorescence technology and have the ability to further reduce energy consumption through intelligent dimming technology.
No need for as many replacements as fluorescent light
As mentioned earlier, the cost of replacing a 8W fluorescent emergency light lamp exceeds the installation cost, considering the labor involved. Or, LED-based lamps do not require so much variation during their useful life.
In addition, before the fluorescent lamps reach their end of life, they decrease over time, resulting in a rated output that is lower than their rated output. However, for LEDs, degradation is slower and therefore critical for emergency lighting.
Improve lighting for high-risk tasks through light control
It is well known that LEDs provide directional light to make the distribution of light more direct. This control allows the light to move to the desired location, such as an escape route and an open area.
Reduce the heat of emergency lights
As LED efficiency is further increased, the heat generation of these devices becomes less. Similarly, the current trend of using more mid-level powered LEDs instead of LEDs with high power also reduces the amount of heat generated. By keeping the battery cooler and generating less heat, the LEDs are suitable for self-contained lamps, ensuring longer product life.
Provide better light quality
A light source with a color rendering index (CRI) greater than Ra 40 performs well when looking for an ideal source of emergency lighting. With such low requirements, we can see that the light quality of emergency lighting does not have to have high standards. However, since main power lighting requires better light quality, there is a tubular LED illumination with a higher CRI to meet this demand.
To see the importance of LED as an emergency lighting source, let us look at its relevance to smart buildings (LED lights).
The benefits of LED technology for smart buildings
As shown by WBS Technology's EMIoT solution, LED lights can be used as a means of digital communication and create a wired intelligent building network.
Lighting plays an important role in modern architecture, and LEDs and fluorescent lamps are potential choices for builders. Although fluorescent lamps are less expensive, LEDs have lower maintenance costs, less heat, no toxins, and lower energy consumption. These features make LED lights ideal for emergency lighting.
LEDs also have the advantage of being easily integrated with wireless technology to form a network with various devices to create an intelligent lighting system. Intelligent LED light systems still have many uses in the construction industry. They include ensuring energy efficiency, safety and predictive maintenance.
