1. Introduction

With the rapid development of LED technology, the demand for LEDs in industrial applications continues to grow. From mechanical equipment lighting to automated inspection systems, LEDs have become a core component in industrial lighting and indication systems. In order to ensure the reliability and efficiency of the system, the correct selection of industrial LEDs is particularly critical.

2. Key performance indicators of industrial-grade LEDs

2.1 Optical performance

Brightness (lumens): Determine the required luminous flux according to the application scenario

Emitting angle: For example, narrow angle (<30°) is used for focusing, and wide angle (>120°) is used for floodlighting

Color rendering index (CRI): It is recommended to use CRI > 80 in industrial lighting situations

2.2 Electrical characteristics

Forward voltage (VF) and current (IF) matching: Ensure stable operation of LEDs

Power consumption control: Low power consumption design helps system energy saving and thermal management

ESD protection capability: LEDs with high anti-static ability should be selected in industrial environments

2.3 Thermal performance

Thermal resistance parameters (RθJA/RθJC): The lower the thermal resistance, the better the heat dissipation

Packaging form: For example, ceramic packaging is better than plastic packaging and is suitable for high temperature environments

2.4 Environmental adaptability

Operating temperature range: Industrial LEDs usually require -40℃ to +85℃ or even wider

Protection level (IP level): If dust and water resistance are required, IP65 or above should be selected
