Product Description
A high-power LED chip is a solid-state light-emitting device designed for high-luminance applications. This single LED unit operates without an integrated driver board, providing flexibility for custom lighting solutions. It requires an external constant current driver and proper heat management for optimal performance.
High Luminance: Delivers intense, focused light output suitable for industrial, automotive, or architectural lighting.
Single-Chip Design: Simplifies integration into custom circuits or fixtures.
No Driver Board: Allows users to select compatible drivers based on voltage/current requirements.
Wide Voltage/Current Range: Typically operates at 3V-3.4V forward voltage, with current ratings from 350mA to over 1000mA depending on power rating (1W, 3W, 5W, etc.).
Thermal Management: Requires a heatsink or PCB with thermal dissipation to prevent overheating and ensure longevity.
Applications
Spotlights, floodlights, and task lighting
Automotive headlights or auxiliary lights
Stage and entertainment lighting
DIY lighting projects and prototyping
Note: Always use with a constant current LED driver and appropriate cooling. Reverse polarity or excessive current may cause permanent damage.
Product Description
An electrical test pen is a handheld safety tool used to detect the presence of AC voltage in conductors, outlets, or circuits without direct electrical contact. It provides visual and/or audible alerts when voltage is detected, making it essential for electricians and DIY enthusiasts.
Key Features
Non-Contact Detection: Safely identifies live wires through insulation (typical range: 90V-1000V AC).
Visual & Audible Indicators: LED lights and beeping sounds signal voltage detection.
Pocket-Sized Design: Portable and easy to use with one hand.
Auto Power-Off: Conserves battery life when idle.
Self-Test Function: Allows users to verify tool functionality before use.
Operation
Press the power button to activate.
Hold the tip near a wire, outlet, or device.
If AC voltage is present, the indicator lights and beeper will activate.
The tool may differentiate between low/high voltage via multi-color LEDs.
Applications
Checking live wires, outlets, or circuit breakers
Verifying power absence before electrical work
Diagnosing electrical faults in home or industrial settings
Safety Note: This tool detects voltage but does not measure exact values. Always follow electrical safety standards and confirm power isolation with a multimeter when necessary.
