The COB light source is widely used in different industries, including automotive, electronics, and consumer goods. The reason is that the light is brighter, and energy consumption is lower compared to traditional lighting sources. Below are the common types of COB light source that are commonly sold.
COB LED lights
COB LED lights are lighting devices that consist one or more light emitting diodes. The diodes are mounted on a circuit board. The board is then mounted on a heat sink. The heat sink helps to dissipate heat from the LED. These lights are popular because they consume less power and have a long lifespan.
COB Work lights
A COB work light is a portable and versatile lighting device. It is widely used for emergency, outdoor and indoor lighting. It uses a chip on a board technology to produce bright and uniform light. The advantages of these lights are they consume less energy and have a long lifespan.
COB Strip light
A COB strip light is a flexible strip that is illuminated using chip on board LED technology. The strip is designed with multiple LED chips that are closely packed. This gives it a brighter and more uniform light output compared to the traditional LED strips. The lights are used for decorative and architectural lighting because they are energy efficient and versatile.
COB Fog lights
COB fog lights are used for illumination when there is fog. They are low to the ground and produce a bright light. The lights are popular because they consume less energy and have a long lifespan.
COB Headlight
COB headlights are chip on board LED headlights. They emit a brighter and more focused beam of light. This improves visibility while driving. The lights are also energy efficient and have a long lifespan.
COB Tail lights
Tail lights that use chip on board LED technology emit a brighter and more uniform light. They are more energy efficient. Additionally, they have a faster illumination time. This improves the visibility of the vehicle.
COB Interior lights
These are automotive interior lights that use chip on board LED technology. They provide brighter and more uniform illumination. This enhances the visibility of the vehicle’s interior.
COB LED lights have different functions and features from traditional lighting sources. Here are some important features and functions of COB LED lights for industry buyers.
Higher Efficacy
COB LEDs have higher efficacy compared to other light sources. The efficacy of a light source is its ability to produce visible light. It is measured in lumens per watt. The COB LEDs produce less wattage and have higher lumens. The higher efficacy of COB LEDs makes them suitable for applications where energy consumption is a major concern.
Better Heat Dissipation
Heat is an important consideration in lighting devices. All light sources produce it during operation. The amount of heat produced varies from one source to another. Traditional LEDs dissipate heat through individual chips. In contrast, chip on board light source LED lights have a better heat dissipation system. They use a metallic substrate that dissipates heat efficiently. The substrate is part of the LED chip. Better heat dissipation allows the COB LEDs to operate at high levels without overheating.
Uniform Lighting
A chip on board light source produces a uniform lighting effect. It has closely packed LED chips that reduce shadows and glares. The uniform lighting makes the COB LEDs suitable for uses where lighting quality is important, for example, in architectural and commercial lighting.
High CRI
The color rendering index (CRI) shows a light source's ability to render colors naturally. COB LED lighting has a high CRI of about 80 or more. A high CRI allows the LEDs to render colors naturally, making them suitable for uses in applications where accurate color representation is important.
Long Lifespan
Chip on board light source LEDs have a long operational life. Their average lifespan can exceed 50000 hours. The long lifespan lowers the need for frequent replacements, making them cost-effective over the long run.
Dimmability
COB LEDs have advanced dimming capabilities. They can be dimmed to a certain percentage without losing their efficiency. Dimming the light sources can save energy and create customized lighting solutions.
Compact Design
The design of the COB LEDs is compact. They consist of multiple chips that are closely packed on a small area. Their compact design allows them to be used in applications where space is a constraint, for example, in small fixtures and devices.
There are various applications of cob light source in different industries. Business buyers can use the source lights in the following scenarios.
Automotive Lighting
Buyers can use cob LED lights in vehicle headlights, taillights, brake lights, turn signals, and interior lighting. The lights provide improved visibility and safety on the road. Also, they add a modern look to vehicles.
Consumer Electronics
COB LED lights are suitable for use in electronic devices. For instance, in laptop and tablet displays, keyboards, and ambient lighting. The light sources provide uniform illumination. Also, they enhance the visibility of electronic device features.
Smartphone Lighting
COB LEDs are integral to smartphone camera systems, flash modules, and front-facing lighting. The lighting improves low-light photography. Also, it enhances facial illumination during video calls and selfies.
Home Lighting
COB LED lights are applicable in living rooms, bedrooms, kitchens and outdoor spaces. The lights create a cozy ambiance for relaxation and entertainment. Additionally, they provide task lighting for reading and cooking. More importantly, these lights enhance the aesthetic appeal of outdoor landscapes and patios.
Architectural Lighting
COB LED lights illuminate buildings, landmarks, and bridges. The lights highlight architectural features and details. This creates a visually appealing effect. Additionally, the lights create dynamic lighting schemes that enhance the beauty of structures.
Commercial Lighting
Business owners use COB LED lights in retail stores. For instance, in clothing, grocery, and electronics stores. The lights illuminate merchandise. This attracts customers and improves sales. Also, they create appealing lighting schemes for restaurants. This enhances dining experiences and ambience.
Industrial Lighting
Manufacturing plants and warehouses use LED COB lights. The lights offer bright and uniform illumination. This improves worker visibility and safety. Also, they reduce the risk of accidents and errors in industrial settings.
Healthcare Lighting
COB LEDs have applications in hospitals and clinics. The lights are beneficial in operating rooms, patient rooms, and examination areas. They provide bright and sterile lighting for surgeries. Additionally, they create a calming environment in patient rooms.
When considering light sources for a certain project, customers should consider several factors to determine the ideal light source for their needs. Here are some important factors to consider when buying COB light sources in bulk.
Heat Management
Buyers should look for light sources with effective heat management systems. Such systems include built-in fans and heat sinks. Proper heat management is important for the optimum performance of the lights. It prevents overheating which can damage the light source and affect its lifespan.
Light Quality
Business owners should choose light sources that offer high-quality light. This is usually measured by a high color rendering index (CRI). A COB light with a CRI of more than 90 will produce high-quality lights that will render colors naturally.
Power Consumption
Buyers should look for COB light sources with low power consumption. Such light sources have a high lumen output per watt. Low energy consumption LED lights are cost effective. They will save customers on energy bills and maintenance costs.
Durability
Buyers should choose durable COB lights. They should consider the construction materials used to make the lights. For outdoor lights, the materials should be weather resistant, especially to water and UV rays.
Beam Angle
Buyers should select COB lights with different beam angles to suit various applications. A narrow beam angle is ideal for accent lighting. A wide beam angle is suitable for general illumination.
Dimming Capabilities
To enhance flexibility and energy efficiency, buyers should choose COB lights with dimming capabilities. The dimmer lights consume less power and extend the lifespan of the light source.
Compatibility
Buyers should ensure the compatibility of the light sources with existing lighting systems. They should check the power supply requirements and other technical specifications to ensure everything will work properly.
