The Lumen Method is a systematic approach to lighting calculations that considers various factors to ensure adequate illuminance in your space. Let’s break down the steps involved:

1. Calculate the Room Cavity Ratio (RCR): This value helps determine how efficiently light reflects within the space. You’ll need the room’s dimensions (length, width, and height) to calculate RCR.
2. Determine the Coefficient of Utilization (CU): This factor accounts for the light loss due to absorption by surfaces and fixtures. You can find CU tables provided by lighting manufacturers or online resources based on your room’s RCR and the reflectance values of your walls, ceiling, and floor.
3. Apply the Lumen Method Formula: The magic formula is: Number of fixtures=(Area×Illuminance×LLF×CU)(Lumens per fixture×Number of lamps per fixture)Number of fixtures=(Lumens per fixture×Number of lamps per fixture)(Area×Illuminance×LLF×CU)​
   • Area: The total area of the space you want to illuminate.
   • Illuminance: The desired lighting level in lux (or footcandles).
   • LLF (Light Loss Factor): Accounts for the depreciation of light output over time due to dirt, dust, and lamp aging. Typically ranges from 0.7 to 0.9.
   • CU (Coefficient of Utilization): Obtained from CU tables based on RCR and reflectance values.
   • Lumens per fixture: The total light output of a single fixture.
   • Number of lamps per fixture: Some fixtures have multiple lamps, so include this if applicable.
4. Example Calculation: Let’s say you have a warehouse with an area of 10,000 square feet, a ceiling height of 20 feet, and you want to achieve an illuminance of 300 lux. You’ve chosen LED high bay fixtures with 20,000 lumens output and an LLF of 0.8.
   After calculating the RCR and referring to CU tables, you find a CU of 0.6. Plugging these values into the formula, you get:
   Number of fixtures=(10,000×300×0.8×0.6)(20,000×1)=72Number of fixtures=(20,000×1)(10,000×300×0.8×0.6)​=72 So, you’ll need approximately 72 LED high bay lights for this warehouse.

Luminous Flux is the physical quantity that measures the total amount of light emitted by a light source (LED or a LED lights fixture), is a key part of LM-80 test,  usually represented in lumens (lm).Luminous flux is usually measured using an Integrating Sphere. It reflects the light-emitting capability of the light source within the visible spectrum and is unrelated to ultraviolet or infrared radiation, as these do not contribute to luminous flux.

Luminous flux – Professional analysis

In physics, the lumen is the amount of light produced by 1 watt of radiant power at a specific wavelength. For example, at a wavelength of 555 nanometers, 1 watt of radiant power is equivalent to 683 lumens. This definition takes into account the human eye’s sensitivity to different wavelengths of light, meaning that different wavelengths of light, even with the same power, will feel different in brightness.

Luminous flux – Understanding by others

In the lighting industry, “lumen output” or “lumen packaging” are common terms used to describe the brightness of a light source, synonymous with luminous flux, and also measured in lumens. You can imagine it like asking how much heat a central heating boiler produces; the brightness of a light source can also be quantified in lumens.

Luminous flux in the LM-80 test

The LM-80 test is an important experiment for evaluating the performance of light sources, where the measurement of luminous flux is a key part. At the beginning of the test, luminous flux is set as a 100% baseline (L100), and then re-measured regularly during the test process to observe changes in luminous flux over time. Typically, luminous flux will initially increase and then gradually decrease, a phenomenon known as lumen depreciation.

Temperature influences luminous flux

The rate of lumen depreciation of LEDs is significantly affected by temperature, with faster depreciation in high-temperature environments. Therefore, the LM-80 test requires tests to be conducted at different temperatures to ensure the accuracy of the results. Manufacturers pay special attention to the temperature control of LEDs when designing LED lights fixtures to maintain their performance.

Long-term prediction of LEDs

The LM-80 report usually provides data for 6000 to 10000 hours, but many lighting applications require a longer service life. To predict the performance of LEDs in the coming years, the Illuminating Engineering Society of North America (IES) has established the TM-21 standard, which provides an accurate prediction method to ensure the comparability of data from different LEDs and manufacturers.

Misunderstanding about LED lifespan

The terms L80 or L70 often mentioned by manufacturers actually refer to the point in the LED’s lifespan when the light output drops to 80% or 70% of the initial value. The rated life of LED lighting fixtures usually refers to the estimated operating hours when reaching L70. It is important to note that after reaching the rated life, the luminous flux of LED lighting fixtures will continue to decrease gradually, which is different from the performance of old light sources such as fluorescent lamps and HID lamps. CPS LIGHTING various lighting fixtures are all aged tested and reliability tested before leaving the factory. If there are dead LEDs or serious light decay, the reasons will be analyzed in detail to improve the defects of the lighting fixtures and improve the reliability of the lighting fixtures.

What is IK Rating?

The IK rating system is a standardized measure of the mechanical impact resistance of LED fixtures. It’s different from IP rating evaluated waterproof and dust-proof, the IK rating indicates the energy level of impact an enclosure can withstand without being damaged. It was established by the International Electrotechnical Commission (IEC 62262 standard), this system rates the level of protection a LED fixture provides against physical impacts, ranging from IK00 (no protection) to IK10 (the highest level of protection).

Why IK rating is important for LED lights?

IK Rated LED lights are important especially if they are in public areas, high traffic areas, commercial environments. High IK rating ensures safety for both environment and people. For some places like football courts, streets, roadside, and sports stadiums, it is critical to ensure that the lights can work properly even if they are damaged or broken because of a certain degree of impact by balls and other objects. With a low IK rating, it’s more likely to be broken which will lead to a hazard, especially in public areas, such as broken fragments or lack of required illumination/information. Therefore analyzing the risk of an impact is important for deciding if you need a fixture with a high/low IK Rating.

Testing and Certification

To achieve a specific IK rating, products undergo rigorous testing. For lower ratings (IK01 to IK06), a spring impact hammer is used, while higher ratings (IK07 to IK10) are tested with a pendulum hammer that delivers more significant energy impacts. These tests simulate real-world conditions to ensure the product’s resilience. All of our LED lights experienced serious test in CPS lighting’s own laboratory, so that making sure our customers receive good quality products and are not afraid of third part agency to test.

Material and Design Considerations

The materials and design of the enclosure significantly influence its IK rating. Common materials used include stainless steel, aluminium alloy, tempered glass, glass-reinforced polyester, and polycarbonate, each offering different levels of impact resistance and other properties like UV resistance and recyclability. Additionally, the thickness and shape of the enclosure play a role; thicker materials and rounded designs can help distribute impact energy more effectively, enhancing durability.

Practical Applications

IK-rated LED lights are used in areas with high risk of impact, such as industrial zones, public spaces, and places prone to vandalism. Ensuring the appropriate IK rating for the intended application can prevent damage, reduce maintenance costs, and enhance safety and reliability. Generally, a bidding LED lighting project require la mps to reach IK08 rating,and some even require the IK10. 

In summary, understanding and utilizing the correct IK rating for LED lights is essential for their performance and longevity in various environments, particularly those exposed to mechanical impacts.

Principle of LED

An LED consists of a PN junction, which is a combination of a P-type semiconductor (with an excess of holes) and an N-type semiconductor (with an excess of electrons). When current flows from the P-type layer to the N-type layer, electrons and holes combine near the PN junction, releasing energy. This energy is emitted in the form of photons, producing light.

Future trend of LED

The Effective Projected Area (EPA) of a flood light refers to the measure of the fixture’s cross-sectional area that is exposed to the wind, as if it were projected onto a two-dimensional plane. This concept is crucial in determining the structural requirements and safety considerations for mounting outdoor flood lights, particularly in areas where wind forces can be significant.

The EPA is calculated using the following formula:

EPA=Frontal Projected Area (FPA)×Drag Coefficient (DC)

Explanation of nouns:

Frontal Projected Area (FPA): This is the maximum cross-sectional area of the flood light and its mounting as installed. It is the area that the wind can “see” head-on and is typically measured in square feet or square meters.

Drag Coefficient (DC): This is a dimensionless number that represents the fixture’s resistance to airflow. It accounts for the shape of the flood light and how much drag it will produce when exposed to wind. The drag coefficient is determined experimentally, often through wind tunnel testing, and can vary based on the shape of the object.

As an example, let’s consider a floodlight with an FPA of 0.25 ㎡ and a DC of 1.2 (which is a typical value for a flat plate but can vary based on the actual shape of the floodlight). The EPA would be:

EPA=0.25㎡×1.2=0.3㎡

How much EPA rate for flood light is good?

The determination of what constitutes a “good” Effective Projected Area (EPA) rate for a floodlight depends on various factors, including the specific environmental conditions of the installation site and the structural integrity required to ensure the floodlight’s stability and safety. There isn’t a one-size-fits-all answer, but the EPA must be adequate to handle the expected wind loads and other environmental factors.

The Effective Projected Area (EPA) rate for an outdoor floodlight is a specific value that is calculated or provided by the manufacturer, based on the floodlight’s design and the environmental conditions it will face. If the floodlight is designed and manufactured with an EPA of 0.3 m², it implies that it should be suitable for a certain range of wind conditions and mounting heights.

Here’s how the EPA is generally used and what factors influence it:

1. Wind Loads: The EPA is calculated by multiplying the wind pressure (which depends on local wind speeds and gust factors) by the frontal area of the floodlight that’s exposed to the wind. Different regions will have different wind load requirements based on climate and geography.
2. LED Fixture Design: The shape and size of the floodlight impact its EPA. A larger floodlight or one with a shape that presents more resistance to airflow will have a higher EPA.
3. Mounting Height: The height at which the floodlight is mounted can affect the wind forces it experiences. Higher installations are typically subject to stronger winds, which means they may require a higher EPA to ensure stability.
4. Regulations and Standards: Compliance with local building codes and standards, such as those from the American Association of State Highway and Transportation Officials (AASHTO) or the Canadian Standards Association (CSA), is crucial. These standards provide guidelines on how to calculate the EPA and the structural support needed.
5. Worst-Case Scenarios: Manufacturers often calculate the EPA for worst-case scenarios to ensure the floodlight can handle the most extreme conditions it might encounter.
6. Installation Specifics: The EPA can vary based on the specific installation, including whether the floodlight is mounted on a pole, a building, or another structure.

When selecting floodlights for outdoor use, it’s advisable to consult with lighting professionals or follow guidelines from reputable sources, such as those outlined in our ultimate guide to outdoor flood lights, to determine the appropriate EPA for a given application. This ensures that the floodlight is not only bright and energy-efficient but also safe and durable in the intended outdoor environment.

The EPA is important because it helps to:

Determine the mounting requirements for a flood light to ensure it can withstand the expected wind loads. Learn more about floodlights and spotlights here.

Assess the safety of the flood light installation, particularly in areas prone to high winds or storms. Guide the design of flood lights to minimize wind resistance and potential for damage. Flood lights with a higher EPA will experience greater wind forces and thus require more robust mounting solutions and possibly heavier or more aerodynamically designed fixtures to ensure they remain secure and functional under windy conditions.

Understanding Corrosion: The Invisible Killer of LED Lights

Corrosion, especially that caused by salt fog, is a primary concern for LED lighting in coastal regions. Chloride ions in salt fog can penetrate the protective layers on the surface of the lighting fixtures, initiating electrochemical reactions with the internal components, leading to oxidation, short circuits, and even complete failure. This corrosion not only affects the appearance of the lights but more importantly, it shortens their lifespan and reduces lighting effectiveness. All of CPS’ products had been experienced serious trials before launch, we are able to provide 2/3/5 years warranty or base on our clients’ requirement to offer a warranty in various harsh circumstance.

Corrosion Resistance Design: Starting from the Source

To effectively prevent corrosion of LED lighting, it is essential to consider it from the design phase. The design should prioritize materials and components with high protection ratings, such as IP68-rated waterproof and dust-proof designs, which can effectively block the intrusion of salt fog and moisture. In terms of material selection, it is crucial to prioritize materials with strong corrosion resistance. For example, stainless steel (316 stainless steel) and aluminum alloys not only offer high strength but also possess good corrosion resistance. Surface treatment is another important method; advanced techniques like fluorocarbon painting (Dacromet surface treatment) can create a robust protective film that effectively isolates corrosive substances from the outside world.

H series LED Heatsink (LED housing) are selected high quality materials and have a advantage design to achieve a excellence performance in heat dissipation and meet IP65 at least. CPS are often entrusted to produce LED lights which are used in harsh circumstance as the target, such as a steel workshop, a seaside port etc. Nowadays, CPS has rich experience in outdoor lighting over decade, which have won a lot of clients’ approval all over the world.

Regular Maintenance: Extending Service Life

Even with anti-corrosion design and materials, regular maintenance and inspection are indispensable. This includes cleaning the surface deposits of the lighting fixtures, checking the integrity of sealing parts, tightening connections, and more. Through these maintenance tasks, potential corrosion issues can be identified and resolved promptly, thereby extending the service life of the lighting fixtures. Unless the LED lights were installed at a very high pole, it is better to maintain each LED lights regularly.

The Conclusion for Corrosion Resistance

The issue of LED lighting corrosion is not insurmountable. By employing reasonable design, high-quality materials, advanced sealing technology, and regular maintenance, we can effectively protect lighting fixtures from the erosion of harsh environments. Choosing the right anti-corrosion strategies not only ensures the long-term stable operation of illumination devices but also saves the costs of replacement and repair, achieving a true win-win of economy and efficiency.
