In the realm of projectors, the spotlight has always been on the "light source." One could even say that the history of projector development mirrors the evolution of light sources. Currently, laser light sources are gaining traction, but new technologies are rapidly emerging. This year, projectors featuring Philips HLD light sources have made a strong entrance. Recently, InASK Indies unveiled two HLD-based projectors in Shanghai, adding another formidable contender to the burgeoning new light source projection market.
The launch of these two InASK Yingshi projectors includes a reflective ultra-short throw series aimed at the education sector and a high-performance engineering series. Both models utilize Philips HLD light sources paired with 3-LCD projection technology. According to reports, the distribution of British English projectors in the Shanghai area is largely handled by Lijing. For Lijing, a company with six years of experience and a solid industry reputation, this partnership with InASK Yingshi represents a strategic move to maintain its competitive edge in the projector market.
The first series targets the education market, featuring reflective ultra-short throw projectors. This series includes three products: NX UT with 0 lumens and XGA resolution, NW400 UT offering 4000 lumens and WXGA resolution, and NU360 UT delivering 3600 lumens with WUXGA resolution. Thanks to their ultra-short throw design, these projectors can project an 80-inch screen from just 50 cm away, meeting the specific needs of educational environments. At competitive prices, these projectors employ engineering-grade LCD panels, ensuring superior image quality. Additionally, they support ±3% vertical lens shift and ±2% horizontal shift, facilitating easier installation.
The second series consists of projectors like DX520, DX620, DW500, DW600, DU450, and DU550. These models boast brightness levels ranging from 4500 to 6000 lumens, with resolutions spanning XGA to WUXGA. For engineering projectors, optical zoom and lens shift capabilities are crucial. The InASK Yingshi engineering projectors offer a full 1.6x optical zoom, a vertical displacement range of ±38%, and a horizontal shift of ±8%, allowing users to project a 100-inch screen from distances between 2.2 to 3.5 meters.
The standout feature of these new products is undoubtedly the cutting-edge HLD light source. HLD, or Philips ColorSpark High Lumen Density LED, was introduced by Philips in 2015. Utilizing advanced chip and packaging technology, it significantly enhances luminous energy density and heat dissipation performance. Through larger-sized chips and multi-chip technology, HLD achieves higher total light output, solving the brightness issues of traditional LED projectors and boosting brightness to 3000-5000 lumens. Consequently, HLD light sources are often referred to as high-brightness LED light sources.
The HLD light source module comprises an HLD module, independent blue and red LEDs, and an HLD driver. At the launch event, the head of Philips Lighting Digital Projection Division highlighted that the breakthrough in this technology involved the use of an HLD stick, which greatly improved light source focus—a critical factor enabling HLD to achieve high brightness.
Beyond enhanced brightness, HLD also excels in color performance. While laser technology has performed well in covering the REC.709 standard color gamut, HLD surpasses it significantly. An independent consumer research firm, Insight Media, surveyed 300 individuals and found that 68% of respondents preferred the Philips ColorSpark HLD LED system projector for its superior contrast, image quality, and color vibrancy. Only 30% opted for laser phosphor technology.
From a safety perspective, HLD light sources eliminate the need for the specialized protective measures required for laser light sources, such as beam expansion and speckle processing. This simplifies product design and reduces costs.
Philips anticipates that advancements in HLD technology will boost brightness by 20% annually, with InASK Yingshi planning to release updated HLD-equipped products. It's foreseeable that within the next 2-3 years, HLD projectors will redefine the projector market.
