Summary: Compared with common integrating sphere, the all-new 3m integrating sphere has many improvements. LISUN engineers add the infrared anti-pinch device, the cross laser positioning and adjustable multifunctional holder base in the integrating sphere. The world famous company Sharp Laboratories of America and some other European companies have purchased the 3m integrating sphere. Here ...
IES TM-30-15 is a document approved by the Illuminating Engineering Society (IES) that describes a method for evaluating light source color rendition. The method encompasses several individual measures and graphics that complement one another and provide a comprehensive characterization of how the light will affect the color appearance of objects. The three highest-level components of the system a...
LED luminaries consist of LED power driver, single LEDs and fixtures, which the LED power driver is like the heart of human, so it is the key part. Since the LED is sensitive semiconductor device and also has the negative temperature characteristics, it needs to be applied in steady state operation and protection in the application, resulting in a drive concept. LED devices is strict with LED powe...
LED manufacturers must learn some basic luminaries’ parameters such as brightness, spectrum and color temperature and so on as standard to identify pros and cons. We will introduce following LED lighting products normal parameters and tell you how to design and improve LED lighting products. 1、Brightness/Luminance Brightness/luminance L: Luminance is the luminous flux per Unit solid angle per ...
As the basic test equipment to measure LED luminaries or other lighting product’s performance, the photometer & integrating sphere system has been used at lighting industry for many years. The first generation test instrument is photometer, then single-monochromator spectrocolorimeter, double- monochromator spectrocolorimeter and developed array CCD spectroradiometer in now days, the lightin...
IEC/EN 62471 is to assess relative optical radiation safety of different lamps and lamp system. It fully replaces IEC/EN60825 regarding the requirements of LED products energy level and adds the requirements of photobiological, including spectral irradiance and spectral radiance. According to the test data, it classify the hazard level of the products, including exemption level, low hazard level, ...
Due to the LED light source manufacturing technology development, widely application layer surface, so in order to ensuring the safety of consumers, UL established UL8750 for LED module and lighting lamps and lanterns and safety standards to regulate the LED lighting products. This standard is the industry sales LED products to North America essential safety norms, apply to the LED as the main sou...
