CREE lighting class XP series LED and road lighting reference program

CREE through persistent innovation to promote the popularization and application of LED lighting, the practice of CREE's mission, leading LED lighting revolution, eliminate inefficient lighting, to accelerate the realization of the wide application of LED lighting. CREE LED lighting class leading technology, to help achieve the road lighting energy-saving effect significantly, and completely in the light efficiency, brightness, illumination, heat and life to reach the national standard of road lighting, faster returns on investment, and intellectual property rights and brand advantages for customers to help our customers to escort, leading market position. Leading technology will better promote the market leader, thereby helping companies in the LED lighting change to get more robust development.

According to the LED lighting field, CREE has launched XM series, XP series, XT series, XB series, CXA series of different price level LED lighting products, fully meet customer product design requirements for different market positioning, to help customers achieve lower system cost and higher performance of lighting products and solutions. This article will share CREE lighting class XP LED and road lighting reference program, while CREE look forward to the future with the industry counterparts to carry out more technical exchanges.

CREE XLamp XP series LED SC fand technology platform innovative based on the combination of high light output, high reliability and high efficiency characteristics. XLamp XP-G2 LED, XLamp XP-E2 LED is more than the previous generation of XLamp XP-G LED, XLamp XP-E LED, provides a 20% higher efficiency and more cost-effective for lighting manufacturers (lm/$). At the same time, XLamp XP-G2 LED, XLamp XP-E2 LED can help lighting manufacturers get the same brightness at a lower cost under the condition of the use of LED devices and fewer, also can help improve the level of brightness in the use of the same number of LED devices and under the same power. The new XLamp XP-G2 LED, XLamp XP-E2 LED 85 C temperature test conditions and provide relevant parameters. At the same time, XLamp XP-G2 and LED using the previous generation XLamp XP-G LED the same package size (3.45mm x 3.45mm) and optical design compatible, thus providing the performance of fast and effective promotion to shorten the design cycle and accelerate the LED lighting products market faster. XLamp XP-G2 LED, XLamp XP-E2 LED is widely used in indoor and outdoor lighting to portable lighting and replacement lamps, such as high lumen applications.

Generally speaking, outdoor lighting requirements of high efficiency, high maintenance, Gao Guangtong characteristic, also the relative indoor lighting security needs more and better performance is required in life and reliability. The light effect, light, excellent light color quality, life and reliability is the advantage of CREE XLamp XP series of products. For all kinds of lighting products on the market, the actual case of high efficiency products XLamp XP-G and XP-E LED Series in some module and client application application of street lamp, share and discuss together with lighting manufacturers or designers and other colleagues in the industry.

This design goal for Gao Guangtong, high efficiency, excellent light lamp module, simple structure, easy assembly of lamp design. XLamp XP-G2 LED, XLamp XP-E2 LED is the CREE LED devices with excellent performance, service life, and the color stability based on the good, and the high cost and other factors, the selection of 4500K, color, R3 file is the lamp module design preferred.

XLamp XP-G2 LED, XLamp XP-E2 LED has been tested by LM-80, in line with the requirements of the energy star, which provides a good foundation for safe and reliable street lamp design. The basic performance of XLamp XP-G2 LED, XLamp XP-E2 LED is as follows:

Figure 3 XLamp XP-G2 LED, XLamp XP-E2 LED parameter characteristics

LED lamps need a good cooling system to ensure long-term reliable operation of the lamp.

In the aspect of optics, the scheme of integrated lens is used to support the design of street lamp module. The optical efficiency can reach more than 93% by using Reddick street lamp lens (LL14CR-AOC65150L02).

Figure 5 street lamp lens

Through the combination of 6 parts such as heat dissipation and optics, we have made a series of street lamp modules including LED, aluminum substrate, radiator, optical lens, waterproof and so on.

Comparison of measured data is as follows:

Table 1 XLamp XP-G2 LED, XLamp LED XP-E2 module data measured

The test results showed that the two 14 LED streetlight module can be achieved for high light output, light efficiency is more than 90 lm/W, color temperature and color rendering index reached the street requirements, simple structure, easy assembly, can meet the high quality street design different light efficiency and cost requirements.
