COB LED STRIP

COB LED strip lights are a type of LED strip lighting that uses chip-on-board (COB) LED technology. Here are some key details about COB LED strips:

– COB refers to the LED packaging – instead of individual small LEDs, COB LEDs combine multiple LED chips into a single module or “chip.” This allows for higher light output.

– COB LED strips have the LED chips mounted directly onto a substrate or circuit board. This allows for better thermal management compared to traditional SMD LED strips.

– COB LED strips produce a brighter and more focused light output compared to standard LED strips using SMD LEDs.

– They are more energy efficient and durable than older LED strip lighting technologies.

– COB LED strips are available in a range of colors including RGB options for color-changing effects.

– They are commonly used for accent and task lighting, under cabinet lighting, and decorative lighting applications.

– Higher initial cost but longer lifespan and lower operating costs compared to incandescent or fluorescent lighting.

In summary, COB LED strip lighting delivers brighter, more efficient and more flexible lighting compared to traditional LED strip lights. The COB LED design allows for better light quality in a more compact form factor.

One of the biggest complaints about traditional LED strips is the lighting dot throughout the strip. A lighting dot is a bright area through the strip where you can see where the light is coming from. Light is more soft and attractive when it looks like a smooth light source rather than a lighting dot mess.

With 5050 SMD flex strips, the larger diodes are squeezed close enough so that the light is spread out and consistent across the illuminated surface at a distance. But if the light is too close to the surface or the strip itself is visible, the hot spot is an obstacle that the human eye cannot ignore.

With a 480 chip/M COB strip, it is pretty challenging to pick out any hot spots on the COB flex strip. This strip shines a soft, uniform light from end to end. Even light with no lighting dot is more attractive to the human eye and gives off a steady light even in the narrow places. The only natural way to see the lighting dot is to look at the back of the strip, where it is easier to see the individually placed flip-chip LEDs. You can only see the individual led if you dim strip down to about 5% brightness. This makes COB flex strips ideal for applications where

1. The led strip itself cannot be hidden from view.
2. The surface being illuminated is within 2 feet of the light bar.
3. Reflective surfaces like granite/glass are all around.
4. Those applications where you want an excellent neon effect.

– Under Cabinet Lighting – COB LED strips provide focused, high lumen lighting for kitchen counters, shelves, and displays.

– Cove Lighting – Installing COB LED strips in coves provides attractive indirect illumination.

– Task Lighting – The narrow beam angle makes COB LEDs ideal for workstations, desks, and hobby spaces.

– Accent Lighting – Use COB LED strips to highlight architectural features, artwork, or accessories.

– Display Case Lighting – Shining COB LEDs in retail display cases spotlights products dynamically.

– Backlighting – COB LEDs can backlight mirrors, alcoves, shelves and transparent signs.

– Outdoor Lighting – Utilize waterproof COB LED strips to illuminate gardens, gazebos, patios and walkways.

– Under Cabinet Lighting – Illuminate the interiors of cabinets, showcases, and shelving.

– Signage – COB LEDs can provide brightness for illuminated business signs and displays.

– Automotive Lighting – Use COB LED strips for custom interior car lighting effects.

– Stage Lighting – Uplight stages, theaters, and performing arts venues.

The high lumen density and energy efficiency of COB LED technology make it versatile for both focused spotlighting and large area illumination. The narrow beam angle helps concentrate light where needed most.

1. LED Chip Expanding – The LED chips undergo a specialized expansion process to enlarge the p-n junction area and enable higher luminous efficacy and tighter chip packing density on the PCB.

2. Die Bonding – Using advanced high-precision pick-and-place equipment, the expanded LED chips are die bonded onto the PCB substrate through eutectic bonding or solder bonding using high-temperature solders or silver-filled epoxy adhesives.

3. SMD Resistor Integration – Precision SMD chip resistors are populated onto the PCB through an automated pick-and-place machine to enable current regulation to each LED.

4. Solder Reflow – The PCB assembly passes through an industrial convection reflow oven with a tightly controlled thermal profile exceeding 165°C to achieve complete solder reflow and permanent electrical interconnection.

5. Phosphor Deposition – The LEDs are coated with a fluorescing phosphor compound matrix through electrophoretic deposition or conformal coating processes.

6. Automated Dispensing – The phosphor/silicone mixture is precisely dispensed onto each LED chip through an automated fluid dispensing system for uniform coverage.

7. Post-Dispensing Cure – The phosphor-coated PCBs are cured in industrial ovens to anneal the phosphor particles and cure the silicone encapsulants.

8. Quality Testing and Inspection – 100% of PCB assemblies undergo comprehensive ICT/Flying Probe testing combined with automated optical inspection.

9. Termination – Low-profile solderable copper pads are terminated at the end of each PCB for connectivity to power supplies.

10. Back-end Reliability Testing – The finished COB LED strips undergo reliability testing, burn-in, and packaging per CE standard prior to shipment.

We put tremendous effort into the design and manufacturing process, using high-quality LED chips, efficient heat dissipation, and waterproof coatings to further enhance product stability and durability. Users can have peace of mind when using our products, as we are confident to provide a 5-year warranty. This is an industry-leading level among similar products.

COB LED strips offer high brightness, high efficiency, long 50,000 hour lifespan, flexible installation, pure uniform lighting, and energy savings compared to other types of LED and conventional lighting.

Common placement spots include under cabinets, display cases, cove lighting, accent walls, pathways, staircases, decorative and task lighting, outdoor areas, undercar, and more. Their flexible thin profile allows lighting in spaces other lights can’t fit.

COB LED strips have an adhesive backing for easy peel and stick installation. Connect the low voltage 12V or 24V power supply wires to the end of the strips observing polarity. Be sure to calculate the correct wattage power supply for the total strip length. And CREELUX also has DC5V and AC110V, AC220V COB LED Strip. 

The COB LED Strips can be shortened by cutting at designated intervals marked on the strip. Simply resolder new connections to rejoin the ends. Polarity must be maintained for proper functioning. Connectors are often included. CREELUX also provide Mini Cutting Series, it’s a good choice for customer too. Please contact us if you’re interested.

CREELUX Neon Series of COB LED Strip is IP67, waterproof rated for wet location usage outdoors. Check specs to ensure strips have silicone coating and waterproof power connectors.
