Product Application


3. High Bay Light: 300W UFO LED High Bay The 300W UFO high bay light emits 45,000lm at 6500K daylight, replacing 600W HID fixtures in warehouses, sports arenas, or manufacturing plants. With a 120° beam angle and IP66 waterproof rating, it withstands dust and water jets. Technical specs: 150lm/W efficiency, 100-277V AC input, and 100,000-hour lifespan. The aluminum heat sink reduces maintenance costs by 70% compared to traditional lighting. 4. Digital Microscope: 4K USB Digital Microscope This 4K digital microscope (3840x2160 resolution) offers 20-2000X magnification via a 12MP sensor, connecting to PCs/tablets for real-time 4K video recording. Equipped with 16 adjustable LED lights and a 3D measurement function, it features a flexible stand for 360° viewing. Technical features: 0.1mm depth of field, 5-30cm working distance, and compatibility with Windows/macOS/Linux. Ideal for electronics repair, semiconductor inspection, or educational research.

The Hongxuan(Shenzhen Hongxuan Optoelectronic Technology Co.,Ltd) lens offers low-profile lenses specifically designed for the Luxeon LEDs, OSRAM LEDs ,Bridgelux LEDs or Seoul LEDs,Cree LEDs. A software-optimized aspheric profile enables the generation of several different beam output patterns:narrow,medium,elliptical and wides beams. The high collection efficiency reaches 85% of the total flux emitted by the LEDs. Lens holders are available in white or black,and provide the proper alignment the between the LEDs and the lenses,set correct distance between the lens and LED. The lens holder can be glued to the PCB to provide a secure assembly.

The LED lenses are for CREE,Lumileds,Osram,Seoul,Nichia,Bridgelux,Citizen,Prolight LEDs.and can provide street light lens,flood light lens,lighting lens,MR16 lens,Par22 lens,Par30 lens,Par38 lens,stage lighting lens,flashlight lens,hybrid light lens. These TIR optics are used to get narrow beams with smaller LED's or allow you to use the larger source LED’s and even multi chip LED's. As with the other TIR ranges, we have a number of beams to allow you to use the same size optics for a number of beam angles.
