D light source and traditional light source have great differences in physical size and spatial distribution of light flux, spectrum and light intensity. LED detection cannot copy the detection standards and methods of traditional light sources. Xiaobian below introduces the detection technology of common LED outdoor lighting. LED outdoor lighting optical parameter detection 1. Luminous intensity detection Light intensity, the intensity of light, refers to the amount of light emitted at a particular angle. Due to the concentrated light of the LED, the inverse square law is not applicable in the close range. The CIE127 standard specifies two measurement averaging methods: measurement condition A (far field condition) and measurement condition B (near field condition) for measurement of light intensity. In the case of light intensity, the detector area of both conditions is 1 cm 2 . Normally, the luminous intensity is measured using standard condition B. 2. Luminous flux and light ef...

Now the application of 200w led flood light is gradually becoming wider. It belongs to high-tech lamps and is now accepted by consumers. Since it is a new technology product, it also needs to know the precautions it installs in the factory floor to prevent accidents. happened. 1. The installation personnel must be required to hold a professional electrician's certificate during installation so as to avoid the installation error and damage the LED floodlight; 2. Before installation, the integrity of the 200w led flood light and the completeness of the accessories must be carefully checked; 3. At the time of installation, the LED floodlight temperature connection cable can be connected from the drill hole through the wiring behind the lamp, and can be installed with the wire clamp, so as to ensure the installation is firm; 4. At the time of installation, the product and the flammable materials should be at least 0.2m away. It is necessary to ensure that the installed zenith has a gap...

LED flood light is a point source that can be uniformly illuminated in all directions. Its illumination range can be adjusted arbitrarily and appears as a regular octahedron in the scene. Floodlights can be placed anywhere in the scene. For example, it can be placed outside the scope of the camera or inside the object. It is common to use many different colors of floodlights in the scene. These floodlights can project darkness and blend on the model. Because the floodlights have a large illumination range, the floodlights are very easy to predict, and there are many auxiliary uses for this kind of light. For example, if the floodlight is placed close to the surface of the object, it will be on the surface of the object. Produces bright light on it. Main application areas: hotel exterior wall, square night view, garden lighting, interior decoration, outdoor flooding, construction site, aerial work vehicle, art place, factory building, gymnasium, golf course, shop, subway station, gas...

The Point light source is idealized as a Point light source. Point light sources are abstracted physical concepts in order to simplify the study of physical problems. Just like the smooth plane, the mass point, and the air resistance, the point light source does not exist in reality, and refers to a light source that uniformly emits light from a point to the surrounding space. Point light source is a new type of decorative light, mainly used in building signs, KTV bars and other outdoor decoration. LED point light source is a new type of energy-saving and environmentally-friendly decorative lamp. It adopts LED cold light source to illuminate. It has built-in microcomputer chip, which can be programmed and controlled at will. Multiple simultaneous changes. Monochrome change can also realize synchronous colorful gradient, jump, scan, and water light. Full color change effect and multiple led point light sources form a dot matrix screen. It can change various pictures, texts and animat...
