According to analysts of "Fortune Business Insight", the global LED lighting market is currently experiencing a year -on -year growth of double digits. It is expected that from now to the end of this century, the compound annual growth rate will continue 19.2%.This is equivalent to at the end of this period, its annual value is nearly $ 300 billion.In order to share this favorable opportunity, LD manufacturers need to develop the limits that can break through the performance limit and provide significant differentiation for end usersofproduct.

By improving performance characteristics, the new generation of LED canSignificantReduce the number of devices that need to be installed in lighting equipment.Therefore, the overall fixed device cost is reduced, and it also makes it more compact.Innovation brings a higher driving current value and lower thermal resistance value, and provides a wider range of related color temperature (CCT) and color rendering index (CRI) options.In addition, optical devices that are particularly suitable for specific application scenarios have brought considerable returns.

In any industry, when a complete product line has been significantly improved, the current users and new users will notice this.In this regard, high -power LEDs are no exception -the upgrades of existing design and new designofThe implementation of the system has benefited.

LED revolution

The Cree LED XP-G LED, which was initially launched in 2009, represents a breakthrough in performance and helped create a new era of solid lighting.These launch devices generate up to 400 light output at a current level of 1A, only350maAt the current level of more than 130iumns/W, 43%brighter than their previous generations, 53%higher efficiency.

A few years later, XLAMP XP-G2 LED will supportofThe output of the lingering output increased by 20%.When the XLAMP XP-G3 device came out in 2016, the lingering output increased by 31%, and the flow/W also increased by 8%.Now, with the release of XLAMP XP-G4 launcher products, this standard has been further improved.

The devices in this new LED series can provide 75%more lumen than the XP-G2 similar device, lower thermal resistance, 1.3 ° C/W.These LEDs have been widely accepted in the implementation of outdoor lighting, portable lighting, indoor lighting and solar lighting.In addition to the benefits of enhanced performance, sharing the same area as the original XP-G, XP-G2 and XP-G4 LED sharing means seamlessupgradePath and shortened design cycle.

The improvement of XLAMP XP-G4 LED products is based on the latest raw materials, packaging and chip technology.The effective use of ceramic high -power LEDs in many directed lighting applications usually means one -on -one configuration and special optical devices.XP-G4 LED has a generation than previous generationsEvenSmall luminous surfaces (LES) and 69%of the strength, which is closer than previously closer beam angles and higher Campra values.

For the XP-G3 family (see Figure 1), we must weigh with glow to maximize the efficiency and long-term operation reliability.In contrast, the XPG4 series introduces a highly optimized optical outline to emphasize the output of the axis and provide a greater enhancement function than the previous LED series.Compared with the XP-G3 device, the maximum light output of the XPG4 device increases by 41%, up to 1130 lumens.

Using proprietary technologies can better guide the launching light to a narrower and more uniform cone.This leads to 120 ° at the maximum half -maximum value (FWHM) in the neutral white neutral angle.Smalled launch, reduced overflow and clear LES make the new LED series very suitable for targeted lightingdeploySuch as spotlight, advanced torch and stadium lighting.

The flat and smooth phosphorus light layer produces a superior color than the outline of the angle.In addition, andcompeteCompared with the opponent's high -power LED, the 70 ° deadline has significantly improved the coupling efficiency with secondary optical devices.
The new generation XP-G has a CRI option of 1800K to 6500K and 70, 80, and 90.Apart fromalreadyIn addition to the applications, other uses include architecture, entertainment and garden lighting.
