  LED Lighting Supports Sustainable Fishing and Protect Local Habitat

  LED lighting technology helps to enhance sustainability not only by reducing general energy consumption, it also prevent wildlife in many ways. Recently in Alabama, USA, a turtle-friendly LED lighting is installed in the Gulf Coast to protect a wide variety of sea turtles living in the area. Also, Bangor University in the UK found that attaching LED lights to big holes in net can guide non-target species to escape and significantly reduce bycatch.

  Outdoor and Industrial Lighting Applications

  High Bay Light ,LED Wall Pack,Parking Lot Light, and high-bay fixtures require high flux and efficacy to meet the ever increasing demands for system efficiency and energy cost reduction for these applications. [LUXEON 5050 LEDs are already installed in millions of fixtures worldwide and this performance enhancement extends the energy efficiency and long life benefits that cities and business require," said Mei Yi, Product Marketing Manager [Our manufacturing capabilities allow us to offer even higher typical performance – 684 lumens with our two lowest Vf bins – for customers that require extraordinary light output." Color stability and consistency too are critical factors in most outdoor and sports arena types of applications and LUXEON 5050 LEDs are hot-color tested to ensure the LEDs fall within the specified color bins at typical application conditions of 85°C. LUXEON 5050 with the round LES is offered in color temperatures from 2200K to 6500K at 70, 80 and 90CRI, and with 6V or 24V options. It is an ideal drop-in replacement for emitters with industry standard 5.0 x 5.0 footprint.

  Analysis of LED lamp power deviation

  First, due to cost pressures, the production process cut corners and cut corners, eliminating the necessary product testing procedures, and the unqualified products were not eliminated in the factory and flowed to the market as shoddy products. Second, the LED lamp bead has insufficient heat dissipation design margin, and the deviation of the assembly process and the incoming materials causes the lamp bead to overheat, and the forward voltage drop (Vf) drops out of control, causing the actual power of the lamp to deviate from the lower limit. Thirdly, the thermal stability of the optional driving power supply of the lamp is poor, and the temperature drift of the output current is large, which directly causes the lamp power to deviate in a large range. Fourth, in order to reduce the cost of purchasing LED lamp beads, the lamp beads purchase did not select the LED Vf distribution BIN according to the design requirements, which caused the actual LED power consumption to deviate from the design center value. Fifth, the constant current accuracy of the optional drive power supply is low (generally 5%-8%), and it cannot be adapted to the Vf BIN with various lamp beads.
