Have you ever looked for lights and saw the words “COB light” but had no clue what it stood for? You are not the only one.
From stage and studio lighting to even car headlights, COB lights seem to be everywhere! But what is COB lighting, and why is there a noticeable trend towards its use?
This guide explains the basics of COB lights: their operation, applications, growing popularity, and possible market options. You will see that after reading this article, you will have the answers to what COB lighting entails and if it meets your requirements.
What Does COB Stand For?
The term COB refers to “Chip On Board”. It describes a more advanced LED lighting technology in which several LED chips are grouped closely together and then mounted onto a circuit board.
Instead of emitting numerous small lights, now there is a single smooth and bright light extractable.
Unlike traditional LEDs that feature multiple points of light, COB LEDs appear to be glowing panels. That’s the magic of COB: it produces seamless, high-quality beams illuminating spaces without gaps.
How COB Lights Work
Regular LED lights function very differently from COB (chip on board) lights. With standard LEDs, each diode is separated, and when you turn it on, you see a collection of small light points like stars shining.
COB lighting differs because the manufacturers gather multiple tiny LED chips and place them in one single location. Chips are mounted onto a substrate, which is a base layer, and then a phosphor coating is applied over it to produce the desired color parameters.
This design gives you:
- Increased illumination levels
- Enhanced heat release capabilities.
- Greater energy efficiency savings
- Lack of shadowing effects/light fuzziness.
This method provides sharp visibility without creating glare or scattering the light.
Where You will See: COB Lights Applications
Are you wondering where you can apply COB lights? Below are some key areas where they can be put into use:
1. Stage Lighting
Live performers need specific equipment best suited for their work. They require strong, intense heat, which will cover broad areas—COB stage lights give off intense, broad heat.
2. Home Lighting
Modern homes tend to include these lights, as their aesthetics attract homeowners since they appear simple and sleek yet brighten up spaces evenly.
3. Studio & Photography Lighting
Given the soft and natural illumination of COB lighting, photographers will find their work easier, as it helps in lifting the tone during portraits, products, and video shoots.
4. Automotive Lighting
COB LEDs have found their use in the headlights, taillights, and fog lights of modern cars and motorcycles. These features not only add to the beauty of a vehicle but also offer durability.
5. Torches And Flashlights
For camping or hiking, compact COB flashlights are very useful and can be carried easily due to their slim design.
6. Commercial Areas
Cob lamps can be used in shops and hotel reception rooms because they help set the right mood while keeping energy expenses down.
Advantages of COB Lighting
Let's explore one by one the benefits that have informed people's decision to use COBs these days.
1. Consistent Light Distribution
With COB LEDs, you will not see any multiple shadows or dotted light; they give one strong and even beam, which makes them suitable for photography, video recordings, stage performances, or setups that require good imaging.
2. Greater Brightness
With all chips being closely positioned to each other, you can easily trust that with the use of less energy, greater lumens output will be achieved when using stat-powered cob lights.
3. Effective Cooling System
LED lights cannot endure excessive heat, and since COB designs lanterns are better at managing their heat, they remain cool even after hours of use, making them safer and more dependable as well.
4. Energy Efficiency
The increase in brightness that COB lights produce is accompanied by a decrease in power consumption. Power bills will be minimized while, at the same time, the carbon footprint is reduced.
5. Compact Design
With dense chip layouts, COB lights are comparatively smaller and just as powerful, fitting tightly into more compact spaces without performance being hindered.
6. Longer Lifespan
COB lights can last for over 50 thousand hours, which drastically reduces the maintenance work over the course of several years with only minimal upkeep.
Choosing the Right COB Light
If you are not sure where to begin searching, buying a COB light could be daunting. To assist with your search, here is a quick guide:
1. Brightness (Lumens)
Look for the lumens rating, because higher lumens means brighter lights. For home use, users should aim for 800-1200 lumens, whereas stage or commercial users should aim significantly higher.
2. Color Temperature
Do you wish to have warm and soft light or cool, daylight-style light? Select based on the mood you intend to create:
- Warm white ranges from 2700K to 3000K (cozy and relaxing).
- 4000K neutral white (balanced and clear)
- Cool white ranges from 5000K to 6500K (energizing, daylight-like).
3. Beam Angle
Generally speaking, wider angles of measurement (60-120°) are good for general lighting. Narrow beams are excellent for spotlighting and accent lighting (10-30°).
4. Power Consumption
Notice how many watts the light is using. The higher the COBs are rated, the more brightness they give per watt—for example, a 10W COB light can feel very powerful.
5. Heat Sink Quality
Good quality COB lights usually come with strong heat sinks – metal components that pull heat away from the chips, which makes these lights last longer while performing better.
6. Dimmability
If you want controllable brightness levels, make sure the dimmer switch programmed with it can control brightness reductions.
Installation Tips for COB Lights
The process of installing COB lights is relatively easy, but these helpful hints can make the process easier:
- Always turn off the power before installation.
- Hire a qualified electrician when numerous fixtures need to be installed.
- Select appropriate housing for ceiling or wall installations.
- Make sure not to obstruct the heatsink. Ensure that airflow around the heatsink is unrestricted.
- Ensure that rated dimmers and drivers are used for the CO₂ lights.
If using COB lights for an event or theatre production, look into brackets that allow flexible positioning along with cooling fans.
Are COB Lights Safe To Use?
They are often even safer than traditional lighting.
- Compared to halogen and incandescent bulbs, they do not emit as much heat.
- They are eco-friendly and don’t contain mercury.
- Put out fewer UV rays.
- Shock-resistant and constructed with long-term durability in mind.
Just ensure you are buying from trusted brands. Checking certification labels like CE, RoHS, or UL ensures brand safety. Explore well-known and reliable stage lighting brands here!
Downsides of COB Lighting
The advantages of using COB lights do not outweigh their limitations:
- Higher initial cost: Compared to regular LEDs, good-quality bone lights have a higher purchase price.
- Multicolor effects: Versatility in RGB lighting relies greatly on SMD LEDs, unlike COB, which is limited to single-color use.
- Repair is not easy: the entire unit may need to be replaced if a COB chip becomes faulty.
Most users still find the advantages far more useful compared to the drawbacks.
