The Bridgelux family of LED Array products delivers high performance, compact and cost-effective solid-
state lighting solutions to serve the general lighting market. These products combine the higher efficacy,
lifetime, and reliability benefits of LEDs with the light output levels of many conventional lighting sources.
The Bridgelux ES Array Series enables lamp and luminaire designs surpassing efficacy and quality of
light requirements driven by regulatory standards with reasonable system design margins, enabling
lighting product compliance to Energy Star, DLC, Title 24, Part L and other global standards.
The Bridgelux ES Array products are a high performance alternative to conventional solid state solutions,
delivering between 700 and 3000 lumens under application conditions in warm, neutral and cool white
color temperatures. These compact high flux density light sources deliver uniform high quality
illumination without pixilation or the multiple shadow effect caused by LED component based solutions.
To simplify system design for appropriate light output, Bridgelux LED Arrays are specified to deliver
performance under typical use conditions.
These integrated plug and play solutions reduce system complexity and enable miniaturized cost-
effective lamp and luminaire designs. Lighting system designs incorporating these LED Arrays deliver
comparable performance to that of 60-200 Watt incandescent and halogen, 7-42 Watt compact
fluorescent, and 18-50 Watt HID based luminaires and feature increased system level efficacy and
service life. Typical applications include replacement lamps, task, accent, spot, retail, track, down light,
low bay, wide area, security, wall pack and street lighting.

Product Nomenclature
The part number designation for Bridgelux LED Arrays is explained as follows:
BXRA – AB C DEFG – H – IJ - KLM
Where:
BXRA – Designates product family
AB – Designates the nominal ANSI color temperature; 27 = 2700K; 30 = 3000K, etc.
C - Designates minimum CRI; C = 70, E = 80, G = 90
C++ 属于面向对象的编程语言，OOP的思想不必多说，特别对于复杂的软件工程来说，利用OOP绝对是事半功倍，相对于传统的C来说； 当然用C来写单片机程序无可厚非，已经延续了一个传统，从大学时学的开始到工作岗位，好多人都是一直用C来做，但是既然Keil支持C++编译， 可以用C++来编写你的代码，可以利用高级语言来结构化，清晰化你的程序，为嘛不用呢！哈哈，个人看法！下面进入正题： C+...[详细]
