Core tip: Dimming curve is one of the important parameters of dimming equipment, it directly affects theThe effect of light output is the embodiment of the performance of digital dimming equipment.

The above sentence contains three points, we analyze it by article.

Dimming curve is one of the important parameters of dimming equipment.This article refers to the dimming equipment is not limited to the light console this point, usually with dimming related things, are dimming equipment. The most common are the silicon boxes. The dimming curve is one of the most frequently cited parameters in these equipment manuals. Dimming curve in short, it is a dimming device after receiving the input signal according to the predetermined function of the output of light, this function image is the dimming curve. The x-axis represents the input, expressed as a percentage, and the y-axis represents the output, represented by a 0-255 value. dimming curve and light output effectDimming curve There are many kinds of equipment in the factory will have a preset, support users to switch different curves, we commonly used are the following two. These two curves are the default curves of the dimming device, and there is almost no difference in visual sense, but the former more emphasis on the linear output. A pass-through line is a typical way of changing a dimming silicon box into a straight-through silicon box, once the device has received a signal to maintain full value operation. The Super S curve is the default light dimming curve for many models of the lamp console, and the advantage is that (traditional Tungsten Filament age) when pushing the actuator, the luminaire can have a small preheating process. When it comes to traditional lighting, you have to say the following two brothers. One is a 90% linear line, one is a 80% linear line, they are used in a silicon box for traditional Lamps Dimming The occasion is very useful. Even if the lamp is rated at a nominal voltage range of 240V, an appropriate voltage limit is applied to the output values in areas where the voltages are not stable. There are some less commonly used curves, just like these, think about what effect it will be. Did I say that using linear lines would get the perfect linear intensity output? Of course not! So how do you get a smoothWhat about illuminance output? This is the goods, looks a bit ugly, seems to be a close relative of the S curve, using this curve can be obtainedthe uniformity of brightness has changed. Do not forget that the dimming curves are very simple mathematical graphics, and the usual functions are not just these. There are also sine, cosine, radical, cubic, and so on, which are applied to the built-in effects of the light console by overlaying, modifying, shifting, or creating new curves for rich or original variations. The effect editor in the MA console also has many function images. Therefore, the dimming curve is not only the basic knowledge of the review, but also should be extended and innovative! Dimming curve is the embodiment of the digital performance of dimming equipmentIf a silicon box cannot customize the dimming curve, then you can speculate that the silicon box is still an analog signal product. If a light console cannot modify the dimming curve, there are too many places for the system to be upgraded. Dimming curves are important, but they are not omnipotent and require all dimming equipment to maintain performance and use the same a curve can work. All Digital products should have the ability to visualize pre-editing footage and Datum parameters according to the needs of the application. This must be the future of the lighting control equipment in the software development direction.
