COB strip light, also known as COB LED strip light, is a type of LED strip that uses Chip On Board (COB) technology. In COB technology, multiple LED chips are packaged together as a single module to form a high-powered LED light source.

Why is it called a COB light?
The COB technology is called so because it involves directly mounting multiple LED chips onto a substrate material instead of packaging each LED chip individually. The substrate material can be a ceramic, metal or silicon wafer. The resulting LED package is then encapsulated with a phosphor layer and a lens cover to produce a high-powered and energy-efficient light source.

Advantages of cob strip light
COB strip lights offer several advantages over traditional SMD LED strip lights. Firstly, COB technology allows for a higher density of LED chips per unit area, resulting in a higher brightness and greater illumination. Secondly, COB strip lights have a higher color rendering index (CRI), which means they can produce more accurate and natural colors. Finally, COB strip lights have a higher energy efficiency and a longer lifespan compared to traditional LED strip lights.

COB strip lights are commonly used in commercial and industrial lighting applications, such as warehouse lighting, shop lighting, and street lighting. They are also used in residential applications, such as under-cabinet lighting, accent lighting, and task lighting.

COB strip lights are a type of LED strip that utilizes Chip On Board technology to provide a higher brightness, color accuracy, energy efficiency, and lifespan compared to traditional LED strip lights.

How to select cob strip light for ordinary users?
When selecting a COB strip light, ordinary users should consider the following factors:

Brightness: The brightness of the COB strip light should be chosen according to the application scenario. For example, if it is used for general indoor lighting, a strip light with a brightness of 1000-2000 lumens per meter is sufficient. However, if it is used for task lighting or high brightness applications, a strip light with higher brightness, such as 3000-4000 lumens per meter, may be necessary.

Color temperature: COB strip lights are available in different color temperatures, from warm white (2700K-3500K) to cool white (6000K-6500K). The color temperature should be chosen based on the intended use of the light and personal preferences.

CRI: The Color Rendering Index (CRI) measures the ability of a light source to reveal the true colors of objects as compared to natural light. A high CRI value is desirable for applications where color accuracy is important, such as in retail stores or art galleries.

Power consumption: COB strip lights come in different wattages, and choosing the appropriate wattage will depend on the desired brightness and the length of the strip light. It is important to select a strip light with a power consumption that matches the power supply being used.

IP rating: The Ingress Protection (IP) rating indicates the level of protection against solid and liquid particles. For outdoor or wet area applications, it is important to choose a strip light with a higher IP rating to prevent damage from moisture or water.

Dimmability: If dimming is desired, it is important to choose a COB strip light that is compatible with the dimmer being used.

Length: COB strip lights come in different lengths, and it is important to choose the appropriate length for the intended application.

By considering these factors, ordinary users can choose the appropriate COB strip light for their needs.
