In the fast-paced world of lighting technology, the demand for energy-efficient, durable, and high-performance light sources continues to grow. Among the myriad options available, the 3W COB LED Chip stands out as a versatile solution for both commercial and residential applications. Designed to deliver optimal brightness while minimizing energy consumption, this component has become a go-to choice for manufacturers, DIY enthusiasts, and lighting professionals alike. If you’re considering integrating this technology into your projects, understanding its key features, applications, and selection criteria is crucial—and this guide is here to break it all down for you.
At the forefront of supplying high-quality 3W COB LED Chips is Shenzhen Liandun Optoelectronics Co., Ltd., a China-based manufacturer with a track record of exporting to key markets like Canada, Brazil, and the United States. With a focus on reliability and performance, the company’s 3W COB LED Chip (available at https://www.6688789.com/sell/show-736.html) is engineered to meet the rigorous demands of modern lighting systems. From long operational lifespans to impressive color accuracy, this product addresses the core needs of users seeking to upgrade their lighting setups without compromising on quality.
One of the most compelling reasons to choose a 3W COB LED Chip over traditional lighting components is its exceptional efficiency. Unlike incandescent bulbs or even standard SMD LEDs, COB (Chip-on-Board) technology packs multiple LED dies onto a single substrate, resulting in higher luminous efficacy and more uniform light distribution. For instance, Shenzhen Liandun’s 3W COB LED Chip boasts a luminous efficacy of 110 lm/W—meaning it produces 110 lumens of light per watt of energy consumed. This not only reduces electricity bills but also aligns with global sustainability goals by lowering carbon footprints.
Another critical factor that sets the 3W COB LED Chip apart is its durability. With a rated working lifespan of up to 12,000 hours, this component outperforms many competitors in its class, minimizing the need for frequent replacements. This longevity is further backed by a 3-year warranty from Shenzhen Liandun Optoelectronics Co., Ltd., a testament to the manufacturer’s confidence in its product. For businesses operating 24/7 lighting systems (such as retail stores or industrial facilities) or homeowners looking for low-maintenance solutions, this combination of lifespan and warranty offers unparalleled peace of mind.
To fully leverage the benefits of the 3W COB LED Chip, it’s essential to pair it with compatible components and understand its application boundaries. While the chip excels in general lighting, spotlights, and customized projects, factors like heat dissipation and voltage compatibility can impact its performance. In the following sections, we’ll dive deeper into technical specifications, practical use cases, and expert tips to help you make informed decisions—whether you’re a seasoned lighting engineer or a hobbyist embarking on your first DIY project.
Key Technical Specifications of the 3W COB LED Chip
Understanding the technical details of the 3W COB LED Chip is the first step toward selecting the right component for your needs. Below is a comprehensive breakdown of its core specifications, based on data from Shenzhen Liandun Optoelectronics Co., Ltd. and industry standards.
Specification | Value | Description |
|---|---|---|
Power Rating | 3W | Standard rated power for optimal performance; compatible with most 3W-driven lighting systems. |
Luminous Efficacy | 110 lm/W | High efficiency, producing bright light while minimizing energy use. |
Color Rendering Index (CRI) | 80Ra | Ensures accurate color representation—ideal for applications where color accuracy matters (e.g., retail displays, art galleries). |
Working Lifespan | Up to 12,000 hours | Long operational life reduces replacement frequency and maintenance costs. |
Warranty | 3 years | Manufacturer-backed coverage for defects in materials or workmanship. |
Origin | Guangdong, China | Produced in a region known for advanced electronics manufacturing. |
Package Dimensions | 1cm x 1cm x 1cm | Compact size, suitable for space-constrained designs (e.g., small spotlights, decorative fixtures). |
Gross Weight | 0.050 kg per unit | Lightweight, simplifying shipping and integration into lightweight fixtures. |
Minimum Order Quantity (MOQ) | 50 pieces | Ideal for small-scale projects or bulk orders, with discounts available for larger purchases. |
Price Range | $0.14–$0.36 per unit | Cost-effective pricing, with 20% discounts on bulk orders to reduce project costs. |
These specifications are not just numbers—they translate directly to real-world performance. For example, the 80Ra CRI ensures that colors appear true-to-life, making the chip suitable for residential lighting where warmth and accuracy matter, as well as commercial settings like clothing stores or museums. The compact dimensions, meanwhile, allow for flexible design possibilities, from slim ceiling spotlights to portable work lights.
Practical Applications of the 3W COB LED Chip
The 3W COB LED Chip’s versatility makes it suitable for a wide range of lighting scenarios. Its combination of power, efficiency, and size allows it to adapt to both indoor and controlled outdoor environments. Below are the most common and effective applications:
1. General Lighting
For residential, commercial, and industrial spaces, the 3W COB LED Chip serves as an excellent general lighting solution. Its 3W power output and 110 lm/W efficacy provide sufficient brightness to illuminate rooms, offices, or factory floors without overconsuming energy. For example, a single chip can replace a 25W incandescent bulb in a bedroom, while multiple chips can be arrayed to light up larger areas like warehouses. The long 12,000-hour lifespan also means fewer bulb changes, a major advantage for high-ceiling spaces where maintenance is difficult.
2. Spotlights and Accent Lighting
The chip’s high CRI (80Ra) and focused light distribution make it perfect for spotlights and accent lighting. In retail stores, it can highlight product displays by enhancing color vibrancy; in homes, it can draw attention to artwork or architectural features. When paired with PCB aluminum radiators (a common complementary component), the chip maintains stable performance even when used in enclosed spotlight fixtures—preventing overheating and extending its lifespan.
3. Customized Lighting Projects
DIY enthusiasts and OEM manufacturers will appreciate the 3W COB LED Chip’s compatibility with various components, such as LED chip beads and low-voltage power supplies. It can be integrated into custom fixtures like under-cabinet lights, LED strips, or portable work lights. For instance, a hobbyist building a photography fill light can use multiple 3W COB LED Chips to create a bright, uniform light source, while manufacturers can incorporate the chip into custom industrial indicators.
4. Controlled Outdoor Lighting
While the chip is not explicitly rated for waterproofing, it can be used in outdoor settings when paired with waterproof enclosures or fixtures. For example, it can be integrated into IP68-rated outdoor spotlights (similar to Shenzhen Liandun’s recommended outdoor RGB pixel lights) to illuminate gardens, building facades, or walkways. The key is to ensure proper sealing to protect the chip from moisture and dust, which can degrade performance over time.
