LED Warning Light Components
Components of LED warning light
Light diffuser: used to control the distribution of the beam by narrowing the beam angle, concentrating, and focusing it
Heat sink: The LED when in operation it converts electricity into light hence heat is generated. The heat sink dissipates the heat inside the LED to prevent damage to the diodes.
LED array: The LED warning light contains a whole array of light-emitting diodes.
The diodes are semiconductors with two terminals that allow the flow of current in one direction.
Driver: The driver acts as a transformer that steps down the mains voltage which prevents the damage of its circuit hence making it compatible with the LED.
Fitting: Also known as the cap, this is where the bulb is fitted and connected directly to electricity.
Types of LED Warning Lights
There are various types of LED warning lights in the market. Each type has a specific appearance, size, voltage, and color.
Flash Strobing Lights
Feature a high signaling effect through white bursting lights and are mostly used in industrial facilities and warehouses.
They can also be used as an evacuation signal during emergencies.
In aviation industries, they are used in the determination of aircraft position at night or during low visibility conditions.
These lights are designed to provide an effective warning signal.
A rotating mirror light is used to make it efficient.
The mirror works as the reflector, therefore, giving the focused beam of light more attention. Also, the rotating lights are used mostly on emergency vehicles like ambulances, police cars, firefighter cars and so much more.
Also known as blinking warning light.
The pulsing lights are designed to help with safety in hazardous working environments like in mines.
Pulsed lights are used in machinery to serve as an alarm warning to keep people working in harsh environments safekeeping the process efficiently.
Mode of Operation of LED Warning Light
LED warning lights operate in different modes which allows them to fulfill a specific function.
Operating modes include;
You use this mode when you want to produce effects.
By doing so, flashes of light will be produced in a sequence hence creating a pattern.
You will find the flash lighting mode being used mostly in emergency vehicles and concerts.
Here the spacing of flashlights is very small making it difficult to detect the flashes.
You use this mode in photography since it facilitates a continuous beam.
Best Housing Material for LED Warning Light
You need a material with good thermal stability and sturdy to last long under strenuous conditions.
When the housing material is chosen well, you offer protection to the internal components of the light.
When the internal components are well taken care of, you will automatically improve the life span and efficiency of the warning light.
The main materials used for housing are
Aluminum: it is lightweight, non-toxic, has a great heat sink, and is not affected by adverse weather conditions.
Polycarbonate; has up to 90% transparency making it clear, easy to clean, very strong, and can withstand adverse weather conditions.
Average Lifespan of LED Warning Light
The life span of the LED warning light ranges between 10000-15000 hours meaning you can use the warning lights for approximately 6 years no stop.
Disadvantages of LED Warning Light
- High initial price; when looking at the initial capital cost, the warning lights are expensive compared to alternative warning systems.
- Temperature dependency; the overall performance of the LED warning lights depends on thermal management properties.
Overheating of the lights will damage them, therefore, reducing lamp lifespan.
- Electrical polarity; one has to source the correct electrical polarity for the warning lights to light up.
Unlike other warning lights that can work under any electrical polarity, the LEDs have to be fitted with a rectifier to match the source of polarity.
- Voltage sensitivity; you have to apply a voltage higher than the threshold and current below the rating.
For one to achieve this a series of resistors have to be used.
- Blue hazard; the LED warning lights can exceed the limits of blue light hazard as stated in eye safety specifications.
- Blue pollution; the LED warning lights have a high color temperature.
This means that they emit more blue light compared to conventional outdoor sources, therefore, causing light pollution.
- Area light source; the warning lights are not able to approximate a point source of light hence cannot provide divergence below few degrees.
Cost of LED Warning Light
The LED warning lights are sold at a competitive price yet affordable.
Besides, the price depends on size, where to be used, and mostly the cost of production.
The LED warning lights are relatively expensive compared to the traditional light source. This is because of materials used in their production, the long lifespan, and also have higher efficiency.
Due to their long lifespan, they cost less.
The prices of the warning light range from around 3 USD.
How Color Temperature Works with LED Warning Light
LED light color temperature
Color temperature refers to the warmth or coolness of light.
The color temperature is measured in kelvins. Whereby the high temperatures will represent cool colors and low temperatures represent the warm colors.
When choosing the color temperatures, we consider where the warning lights will be used.
What is CRI in Relation to LED Warning Light
Color rendering index (CRI) is the measure of how accurately a light source displays its colors.
We determine CRI by comparing the appearance of a colored object under artificial light.
When the CRI level is low we have more unnatural colors appearing when illuminated with artificial light.
When we have our CRI levels high we have a better rendering of colors by the artificial light.
For effectively rendering colors a CRI value of 80+ is used while when we need very accurate color rendering a CRI value of 90+ is used.
For warning lights, we use a higher CRI value so that colors are visible due to good light rendering.
Selecting Luminous Intensity of LED Warning Light
Luminous intensity is also known as direction flux. It quantifies the luminous flux emitted by a light source in a certain direction.
We measure this in candelas while its viewing angle is in degrees.
The viewing angle of the light source is very important as light is not evenly dispersed.
To determine the luminous intensity of a LED warning light we calibrate the detector of illuminance then calculate luminous intensity using the inverse square law.
The location of the beholder will determine the output of light. Therefore, when the viewing angle is wide enough, a single warning light can be used in an entire building.
To achieve this, diffused lenses are used since they provide a wider viewing angle compared to a clear lens.
Dimmability of LED warning light
First, we need to understand that not all LED warning lights are dimmable, and those designed as dimmable may not work with certain dimmers.
We advise that you read the manufacturer’s packaging instructions so that you don’t use a non-dimmable lamp with a dimmer.
By doing so you may reduce the durability of the lamp.
Dimming the LED lamps helps conserve energy by 50%, which means you use half the normal required energy to illuminate.
Dimming creates less heat in the lamp hence less stress. Thereby increasing the lifespan and therefore add up to a lot of savings.
A dimmable LED warning light gives you flexibility in setting the mood for the situation that you are in.
However, the dimmable LED warning light has the following issues:
Drop out; happens when the LED dims to its maximum percentage hence completely turns off.
The inverse of drop out is pop on that is when you start to rise the light brightness from dimming it pops on to full illumination.
Flickering can be either constant or in irregular intervals.
It can cause loose of driver efficiency hence making it impossible for it to protect the lamp from power surges as it might overheat.
You can dim the warning lights in two ways:
Pulse-width modulation dimming (PWM) works by turning the LED warning light on and off at a high speed.
This allows the warning light to be on for less time, lowering the internal temperature and in return adding the lifespan of the light.
The main setback of PMW is you will have a generation of noise and consequently flickering.
Constant current reduction (CCR) is also known as analog dimming.
When you pass the electrical current that is necessary for illumination of the lamp through it, the current lowers and dims the light.
CCR will help you increase the lifespan of the light as less current passes in the lamp hence less heat will be generated.
In addition to that CCR will not result in any noise generation or flickering.
Importance of Center Beam Candle Power (CBCP) for LED Warning Light
Center beam candle power is the measure of luminous intensity at the center of the directional source of light.
Among the fixtures of the same delivered lumen, CBCP could vary depending on the beam angle.
CBCP will create a more use case-specific matrix for the determination of lights in a given space.
When you take CBCP into account you are sure to have the right light distribution for your application.
Therefore, CBCP is more effective when it comes to the selection of lights for a given space.
Why you should consider Efficacy Ratio when choosing LED Warning Light
LED warning light
This is the number of lumens a bulb or lamp produces for each watt it consumes.
When the number of lumens produced is high, this means that the bulb is more efficient.
Efficacy should be given serious consideration as it will help you deliver the same features of lighting using less energy.
Efficacy is calculated by dividing lumens by watts.
Considerations for LED Warning Light Flash Patterns
You will be able to change the flash patterns of your warning light depending on the situation you are in.
To make this possible you apply different power to different pattern select lines.
For white and red warning lights you are advised to use a flash rate of 90 flashes per minute to get the desired attention.
Adding to that, you use a flash rate of 60 flashes per minute to get desirable blue lights.
Your warning lights should concentrate their brief flash to around 20% of the total on-off cycle.
By doing so the flash will get more visual effect from the same amount of energy.
How to determine the Total Power Consumption of an LED Warning Light
When you compare the power consumption of LED to that of the traditional lighting system the latter is high that’s why people are switching to LED lighting.
You use wattage to measure the power supply used in running these lights.
Before you purchase the lights, you need to know their wattage and by doing so you will be able to know how much you will pay for them.
The glowing in LED lights with one end brighter than the other is a result of voltage traveling in the length of wires then gradually dropping in DC circuits.
You are advised to use constant 24-volt strips for long-run applications since they don’t lose voltage quickly.
To determine the total power consumed by the warning light, you will use the following formula;
Power = LED power consumption per foot multiplied by LED strip length.
Also, it is important to note the voltage your strip lights always use to ensure you do not damage the strips when using them hence reducing their efficiency.
For example, when you want to calculate the total power consumption of your LED strip of length 10 feet and power consumption per foot is 6 watts then the total power will be;
10 multiply by 6 giving you 60 watts.
Notable Features of Weatherproof LED Warning Light
In most cases, you will use LED warning lights outdoors.
Here are some of the notable features you should consider
Bright Clear Light
the warning lights are bright and clear hence are visible even in adverse weather conditions.
You can see the warning light when it’s raining or the weather is foggy.
The LED warning lights covers are made from hard glass protecting the inner lamp from rain
Most warning lights have a metal casing to protect them from dust, mud and so much more.
Besides, they should have proper sealing. This will protect the LED warning light system from any form of damage.
So, the light must be IP rated.
Sizing Options for LED Warning Light
The sizing option of the LED warning light greatly depends on where you will use it.
If you are going to place the light in an outdoor setting the sizing is much bigger compared to those that will be used in a building.
You also decide the sizing option with the purpose of the warning light.
For example, the alarm warning lights in a residential house used to alert of fire are not the same as those used in road flares because they serve different purposes.
The material used by the manufacturer also will determine the size of your LED warning light.
Safety Rating Requirements for LED Warning Light
You should place the warning light away from faces because their brightness easily irritates the eyes.
Always place the warning lights in open to make them visible.
Ensure you do not overuse the warning lights because by doing so you could end up causes seizures due to their bright light.
You are only allowed to use the warning lights in times of emergency to not cause a false alarm.
Warranty Duration for LED Warning Light
Most LED warning lights are warranted for a period of one to two years.
If the manufacturer proves that the damage is not their fault, they can avoid the warrant and this mostly happens if you are not careful during installation.
If you buy a cheap LED warning light the warranted period is shorter compared to if you bought an expensive one.
Mounting and Installation Options for LED Warning Light
