    LED Lighting – thermal management

    High Power LEDs develop by the current flow in the semiconductor such as other light sources and heat. To ensure normal luminous flux and life, the maximum junction temperature of the LEDs even in continuous operation are not exceeded. ERCO therefore places particular importance on the thermal management in the light, so that the LED modules operate below the critical temperature range and provide throughout the life of their full capacity. ERCO uses passive heat sinks, which are maintenance-free and reliable, and in contrast to active systems do not consume additional energy. The thermally optimized design reduces the principle of…

    Sony Xperia Z Video

    When capturing video, you can set not only as photos or sports scenes such as night mode, but also take photos while recording video with 1 megapixel. This is done via a second virtual trigger, which was placed over the video trigger. A surprise is the sequence mode. There you can expect as your photos with different effects, which will be shown live – about fisheye lens or drawing. The secret is that all nine possible effects appear reduced simultaneously. With so much calculation in the background, however, it comes to visible imperfections. Panoramic shots are not convincing. A slow…
