Abstract
The field of lighting technology is rapidly evolving. Among these technologies, Light Emitting Diode (LED) systems stand out as highly efficient light sources. LEDs are manufactured with various characteristics and structures. For instance, RGB (Red Green Blue) LEDs are capable of producing a wide spectrum of colors. By using RGB LEDs, it is also possible to achieve white light with different color temperatures Color temperature plays a crucial role in how our eyes perceive the colors of objects. We can observe the true colors of an object under daylight illumination with a color temperature of 6500K. The same object may appear differently under lighting with various color temperatures. Consequently, there has arisen a need to adjust different color temperatures within a single lighting fixture. Existing LED lighting systems often struggle with achieving precise control over color temperature and brightness due to limitations in hardware integration and computational efficiency. Additionally, these systems may require costly sensors or lack the flexibility to adapt to varying environmental conditions. To address these gaps, the proposed system integrates PSoC technology with an AS7261 XYZ Chromatic White Color Sensor, enabling real-time adjustments of color temperature and brightness with enhanced precision and cost-effectiveness. In this study, a design of an adjustable LED luminaire in terms of both brightness and color temperature has been developed using PSoC (Programmable System on Chip) technology, which is gaining significant traction and importance in the field of embedded systems. The necessary XYZ data for the color temperature of the luminaire, which consists of RGB LEDs, were obtained from the AS7261 XYZ Chromatic White Color Sensor. The XYZ information gathered from this sensor was utilized in the algorithm of the designed system. By adjusting the brightness levels at which the RGB LEDs operate according to the desired color temperature and illumination level, the system was successfully implemented. This innovative approach has practical applications in energy-efficient lighting systems, industrial production processes, and customizable illumination solutions for residential, commercial, and automotive environments, highlighting its potential for widespread industrial adoption.

Abstract
Aydınlatma teknolojisi hızla gelişmektedir. Bu teknolojiler arasında, yüksek verimli ışık kaynakları olarak öne çıkan Işık Yayan Diyot (LED) sistemleri bulunmaktadır. LED'ler, çeşitli özellikler ve yapılarla üretilmektedir. Örneğin, RGB (Kırmızı Yeşil Mavi) LED'ler geniş bir renk yelpazesi üretebilmektedir. RGB LED'leri kullanarak, farklı renk sıcaklıklarına sahip beyaz ışık elde etmek de mümkündür. Renk sıcaklığı, gözlerimizin nesnelerin renklerini nasıl algıladığı üzerinde önemli bir rol oynar. Bir nesnenin gerçek renklerini, 6500K renk sıcaklığına sahip gün ışığı aydınlatması altında gözlemleyebiliriz. Aynı nesne, çeşitli renk sıcaklıklarına sahip aydınlatma altında farklı görünebilir. Sonuç olarak, tek bir aydınlatma armatüründe farklı renk sıcaklıklarını ayarlama ihtiyacı doğmuştur. Mevcut LED aydınlatma sistemleri, renk sıcaklığı ve parlaklığın hassas şekilde kontrol edilmesinde genellikle donanım entegrasyonu ve hesaplama verimliliği konularında sınırlamalar yaşamaktadır. Ayrıca, bu sistemler genellikle yüksek maliyetli sensörler gerektirmekte veya değişen çevresel koşullara uyum sağlayabilme esnekliğinden yoksun kalmaktadır. Bu eksiklikleri gidermek için önerilen sistem, PSoC teknolojisini AS7261 XYZ Kromatik Beyaz Renk Sensörü ile birleştirerek renk sıcaklığı ve parlaklık seviyelerini gerçek zamanlı olarak daha hassas ve maliyet etkin bir şekilde ayarlama imkanı sunmaktadır. Bu çalışmada, hem parlaklık hem de renk sıcaklığı açısından ayarlanabilir bir LED armatürü tasarımı, gömülü sistemler alanında giderek daha fazla önem kazanan PSoC (Programmable System on Chip) teknolojisi kullanılarak geliştirilmiştir. RGB LED'lerden oluşan armatürün renk sıcaklığına yönelik gerekli XYZ verileri, AS7261 XYZ Kromatik Beyaz Renk Sensörü'nden elde edilmiştir. Bu sensörden toplanan XYZ bilgileri, tasarlanan sistemin algoritmasında kullanılmıştır. RGB LED'lerin istenen renk sıcaklığı ve aydınlatma seviyesine göre çalıştığı parlaklık seviyeleri ayarlanarak sistem başarıyla uygulanmıştır. Bu yenilikçi yaklaşım, enerji verimli aydınlatma sistemleri, endüstriyel üretim süreçleri ve konut, ticari ve otomotiv ortamları için özelleştirilebilir aydınlatma çözümleri gibi pratik uygulamalara sahiptir ve yaygın endüstriyel benimseme potansiyelini vurgulamaktadır.
