Technology leadership will better promote market leadership and help companies achieve stronger growth in LED lighting revolution.
For the field of LED road lighting, Cree currently introduces XM series, XP series, XT series, XB series, CXA series and other cost-effective lighting-level LED products, fully satisfying customers' product design requirements for different market positioning, helping customers achieve lower Products and solutions for system cost and higher lighting performance. This article will share the Cree Lighting XP series LED and road lighting reference solutions, while Cree looks forward to more technical exchanges with industry peers in the future.
Based on the revolutionary SC® technology platform, Cree XLamp ® XP Series LEDs combine high light output, high reliability and high light efficiency. XLamp ® XP-G2 LEDs, XLamp ® XP-E2 LEDs provide 20% higher light efficiency and higher performance for lighting fixture manufacturers than previous generation XLamp ® XP-G LEDs and XLamp ® XP-E LEDs The price/performance ratio (lm/$).
At the same time, XLamp ® XP-G2 LEDs and XLamp ® XP-E2 LEDs help lighting manufacturers achieve the same brightness and use fewer LEDs at lower cost, and can help use the same number of LED devices and Increase the brightness level with the same power. The new XLamp ® XP-G2 LEDs, XLamp ® XP-E2 LEDs test bins at 85 ° C and provide relevant characteristic parameters.
At the same time, XLamp ® XP-G2 LEDs are available in the same package size (3.45mm x 3.45mm) as the previous generation XLamp ® XP-G LEDs and are optically compatible, providing fast and efficient performance improvements to shorten LED luminaire design cycles and speed up Customer product launch speed. XLamp ® XP-G2 LEDs, XLamp ® XP-E2 LEDs are widely used in high lumen applications ranging from indoor and outdoor lighting to portable lighting and replacement lighting.
Generally speaking, outdoor lighting requires high luminous efficiency, high luminous flux, high maintenance characteristics, etc. In addition, it requires more safety protection than indoor lighting, and requires better performance in terms of life and reliability. Light efficiency, optical communication, excellent light color quality, longevity and reliability are the advantages of the Cree XLamp ® XP series. For the various street lighting products on the market, the high-efficiency series XLamp ® XP-G and XP-E series LEDs are used in some of the module solutions of the street lamp application and the actual application of the customer application, and the lighting manufacturers or designers and other industry colleagues. Share and discuss together.
1. Street light module solution
The design goal is a high-light-pass, high-efficiency, light-distributing street lamp module, which realizes a simple structure and easy to assemble street lamp design. XLamp ® XP-G2 LED, XLamp ® XP-E2 LED is Cree's excellent LED device, based on good performance, lifetime and color coordinate stability, and high cost performance, selected, 4,500K color temperature, R3 The file is the first choice for this street light module design.
The measured data is compared as follows:
