In the LED industry, 2835 and 3014 are package sizes that refer to the dimensions of the LED chip packages. These numbers indicate the length and width of the package, typically measured in millimeters.
Here’s a breakdown of what these numbers represent
2835
The number “2835” refers to a package size commonly used for SMD (Surface Mount Device) LEDs. The first two digits, “28,” represent the package’s length, which is approximately 2.8mm. The last two digits, “35,” indicate the width, which is around 3.5mm.
3014
Similarly, “3013” is another package size used for SMD LEDs. The first two digits, “30,” represent the length, which is approximately 3.0mm. The last two digits, “13,” indicate the width, which is around 1.4mm.
What Are Their Difference?
These package sizes are important specifications when selecting and identifying LED components. The size of the LED package can influence factors such as thermal management, light output, and design considerations.
Different package sizes have various applications based on their size, brightness, and other performance characteristics. Manufacturers and designers choose the appropriate package size based on the specific requirements of the lighting application.
It’s important to note that the package size alone does not provide information about the LED’s performance, such as brightness, color temperature, or beam angle. These aspects are typically specified separately.
