What is the Advantage and Disadvantage of Cob Led 600w

COB LED Definition:

What does COB stand for? According to Wikipedia, COB is the abbreviation of the chip on board. It is a kind of manufacturing where integrated circuits are wired and bonded directly to a printed circuit board, with LED lamps in the front and drive ICs at the back to make up a COB LED module. Then such LED module COB composes an LED display.

The COB LED encapsulation gathers the upstream of LED chip technology, midstream of encapsulation technology and downstream of display technology. As a result, COB LED display could be applied widely based on the upstream, midstream and downstream close cooperation.

Here are some advantages of COB LED:

☛ R&D: There is no diameter of per single LED, and it could be made even more micro in theory.

☛ Technical craftsmanship: COB LED holder cost is reduced, the production process is simplified, the LED chip thermal resistance is lowered, high-density packaging is achieved.

☛ Project installation: It is much more convenient and faster to install of COB LED module.

6 Features as follows:

1. Ultra slim: PCB boards with 0.4mm ~ 1.2mm thickness could be adopted according to clients’ requirements. This makes the weight lighter than about 1/3 compared with traditional LED displays. As a result, it could help to lower down the cost of transportation and project steel structure.
2. Anticollision and crush resistance: For the COB LED, it is to encapsulate the LED chip on the PCB board, then solidify with an epoxy resin glue. The surface would convex as a sphere, making it anticollision.
3. Big view angle: The view angle is about 180°.
4. Good heat dissipation: The COB LED is to encapsulate the LED lamp on the PCB board. It could dissipate the heat easily with the copper foil on the PCB. Besides, the thickness of the PCB copper foil is strictly demanded. Adding immersion gold technology, there is no severe luminance attenuation. So it could prolong the life span of the LED display.
5. Easy to clean: It is enough to use water and cloth to clean the COB LED if there is dust.
6. It is waterproof, damp proof, anticorrosion, dustproof, anti-static, anti-oxidation. Besides, it could work perfectly even it is under -30℃ or above +80℃.

Although COB LED has the above advantages, there are some technical problems need to be solved:

☛ The passing rate is low for one-time encapsulation. And the maintenance cost is high.

☛ The homogeneity of the COB LED display is not as good as that of the SMD LED display.

☛ The COB LED at the moment still needs solid crystal and wire solder craftsmanship, which brings many problems during this process.

☛ The production cost is much higher than the SMD type due to a high failure rate.

Conclusion:

Although COB LED technology has achieved many breakthroughs, SMD LED is still widely applied in P1 or above types. We could say the COB LED display is made only for P1 or below pixel pitch types. And the COB LED could be applied more in the future.

COB LED strip lights are a reliable and creative way to illuminate any space. Light strips are commonly used in various environments such as landscape lighting, playground lighting, carnival lighting, commercial lighting, home lighting, architectural lighting, cabinet lighting, homes, businesses and commercial properties. COB LED strips, also known as pointless LED strips, are particularly interesting because of their continuous line of lighting without hot spots.

What is a COB light strip?

COB light strip is an LED light strip manufactured using COB (Chip on Board) technology. COB technology integrates multiple LED chips on a substrate and realizes the connection between lamp beads through connecting lines, thereby achieving high brightness, High uniformity and high energy efficiency. This makes COB light strips have higher brightness and better color reproduction, and are more energy-saving than traditional LED light strips.

What are the advantages of COB LED strips?

The brightness of COB light strips is very high. One meter of COB light strips can reach a brightness of more than 2,000 lumens, which is enough to meet the lighting needs of many large commercial and industrial places. At the same time, COB light strips also have a wider range of use scenarios and can be used in home lighting, commercial lighting, indoor and outdoor lighting and other occasions.

COB light strips also have excellent color reproduction, allowing people to see more realistic and natural colors. The color temperature range of COB light strips is also very wide. You can choose the color temperature suitable for different occasions, such as warm white (K-K), natural white (K-K) and cool white (K-K).

In addition, COB light strips also have better uniformity and anti-interference. Due to its high chip density, the light is more uniform and there will be no "dots forming lines". During use, COB light strips are also more resistant to interference and more sensitive to changes in voltage, current and other factors.

What are the disadvantages of COB LED strips?

The disadvantage of COB light strips is that the price is relatively high, and due to the high chip density, their product prices are usually more expensive than traditional LED light strips.

Larger heat: Due to the large number of COB lamp bead chips, the heat generated is also relatively large. If there is no heat dissipation design, it will affect the life of the product.

Susceptible to voltage fluctuations: Each LED chip in a COB lamp requires stable current and voltage. If the power supply is unstable, it will have an adverse impact on brightness and lifespan.

Taken together, COB light strips have some advantages and disadvantages compared to traditional LED light strips. Although the price is relatively high, COB light strips are still irreplaceable in high-demand lighting needs such as commercial and industrial places. lighting solutions.
