Key Features of LED Modules
Luminous efficiency and energy savings
LED modules are great at saving energy. They are very efficient at turning electricity into light. This is called luminous efficiency. Modern LED modules can give over 100 lumens per watt (lm/W). Some advanced ones even go beyond 200 lm/W. This means they use less power but shine brighter than old lights.
LED modules save a lot of energy. For example:
They use up to 90% less power than old bulbs.
A study found they cut energy use by 75.65% when replacing regular lamps.
Since 2010, LED efficiency has improved by about 4 lm/W every year.
These improvements lower electricity costs and help the environment. To meet Net Zero goals, LED efficiency must reach 140 lm/W by 2030. That’s 30% better than in 2022. By using LED modules, you save money and help the planet.
CRI and colour accuracy
CRI, or Colour Rendering Index, is another key feature of LED modules. It shows how well a light shows the true colours of things. CRI scores go from 0 to 100. Higher scores mean better colour accuracy. For most lights, a CRI of 80 or more is best for natural-looking colours.
High CRI lights have many benefits:
They make objects look more real and clear.
They help you see better when working or studying.
They can even improve your mood by making spaces feel nicer.
For shops, a CRI of 75 or more is good. For homes, a CRI of 70 works well. Choosing LED modules with high CRI gives better colours and a nicer lighting experience.
Colour temperature and its applications
Colour temperature, measured in Kelvin (K), shows how light looks. It can be warm yellow or cool blue. Knowing this helps you pick the right light for each space.
Warm white light (2700K-3000K): Great for cosy spaces like bedrooms or living rooms.
Neutral white light (3500K-4500K): Good for kitchens, bathrooms, or offices needing balanced light.
Cool white light (5000K-6500K): Best for work areas like garages or hospitals, as it helps focus.
Picking the right colour temperature lets you create the perfect mood. LED modules offer many choices, making them useful for all kinds of spaces.
Heat dissipation and longevity
Getting rid of heat is key for LED modules to work well. LEDs make heat when they turn electricity into light. If this heat isn’t managed, it can build up. This lowers efficiency and wears out parts faster.
Why is heat control so important? Studies show that a 20°C rise in heat can cut LED life by six times. High heat also makes lights dim over time. In powerful LED systems, heat can go over 100 watts per square centimetre. So, good heat control is needed to keep LEDs working longer.
Manufacturers use smart ways to handle heat. Soldering moves heat away better than glue. Sintering, which joins materials with high heat, is great for thin LEDs. These methods stop heat from harming important parts.
Labs test how well LEDs handle heat. Two common tests are:
Test Method | What It Does |
|---|---|
Thermographic Analysis | Uses special cameras to find hot spots on the surface. |
Temperature Cycling Test | Checks performance by switching between hot and cold conditions. |
These tests show if an LED can manage heat and work reliably.
Bad heat control causes problems. Temperatures over 85°C speed up wear and tear. This makes LEDs less bright, changes colours, and shortens their life. Picking LEDs with good heat control means better, longer-lasting lights.
Performance Metrics of LED Modules
Wattage and energy use
When picking LED modules, know wattage and energy use. Wattage shows how much power an LED uses, measured in watts (W). Lower wattage often means less energy used, but not always less brightness. Instead, focus on how efficient the module is.
LED modules are very efficient. They turn most electricity into light, wasting little. For example:
Luminous efficacy shows how much light is made per watt.
High-efficiency modules give over 120 lumens per watt (lm/W).
Standard ones range from 80 to 120 lm/W, balancing cost and output.
Metric | What It Means |
|---|---|
Luminous Flux | Total light made, measured in lumens (lm). |
Connected Module Wattage | Power used by the module, measured in watts (W). |
Luminaire Luminous Efficiency | Light output compared to power used, in lumens per watt (lm/W). |
Choosing high-efficiency LED modules saves money and helps the planet.
Lumens and brightness
Brightness is key when looking at LED modules. It’s measured in lumens, showing total light output. More lumens mean brighter light. But design and colour can change brightness.
Manufacturers test LED modules to ensure steady brightness. Tests check things like resistance and LED size. Always check the lumen rating to match your needs. For example:
A living room might need 1,500-3,000 lumens for a warm feel.
A workspace may need 4,000-5,000 lumens for clear visibility.
Knowing lumens helps you pick the right LED module for each area.
Lifespan and strength
LED modules last long and are tough. Unlike old bulbs, they work for tens of thousands of hours. This means fewer replacements, saving time and money.
Tests like IES LM80 and IES TM21 check how long LEDs last. LM80 measures how light fades over time. TM21 predicts how long they’ll work. For example:
LM80 tests run 6,000 to 10,000 hours to see light loss.
TM21 uses this data to guess life span, often over 36,000 hours.
Test Name | What It Checks | Test Time | Predicted Life |
|---|---|---|---|
IES LM80 | Measures light fading in LEDs | 6000 to 10,000 hours | N/A |
IES TM21 | Predicts long-term light levels | N/A | 6 times test time (e.g., >36,000 hours for 6000 hours tested) |
Picking strong LED modules gives you lasting, reliable lighting.
Compatibility with different lighting systems
When picking LED modules, check if they fit your lighting system. This ensures they work well and give the best results. Testing helps find out how easily an LED module works with various setups, improving your lighting.
Manufacturers test LED modules to ensure they fit systems. For example, the Lutron LED Testing Program checks modules and shares detailed reports. These reports show how well the modules perform and fit. They are shared publicly to help you choose wisely.
