CRE x Ρ – E series LED is used as the light source of the lamp. The main reason is that the series of LED contains white, green, red, yellow, blue and other conventional colors, the color temperature fully meets the requirements of the technical specifications of AIDS to navigation, and has high luminous power and outstanding application advantages.
By changing the current, chemical modification, monochromatic light mixing and other methods, LED light source can realize the luminescence and color change of various colors in the visible light band. Even for white LED, it can also be made into a light source of various color temperatures. Therefore, it has obvious advantages in interior decoration lighting and landscape lighting.
With the development of LED lighting technology, the luminous efficiency of LED light source has increased from less than 10lm / w to more than 100lm / W, and its luminous efficiency still has great potential. By changing the current, chemical modification, monochromatic light mixing and other methods, LED light source can realize the luminescence and color change of various colors in the visible light band. Even for white LED, it can also be made into a light source of various color temperatures. Therefore, it has obvious advantages in interior decoration lighting and landscape lighting.
The basic structure of LED light source is a piece of electroluminescent semiconductor material, which is placed on a shelf with leads, and then sealed with epoxy resin. There is no glass shell in the structure, so it is not necessary to pump vacuum in the lamp tube or flush into specific gas like incandescent lamp or fluorescent lamp. Therefore, the anti-seismic and anti shock performance of LED light source is good, which brings convenience to its production, transportation and use. Compared with the traditional light source, LED light source is small in size and light in weight. It can be made into devices of various shapes, which is convenient for the layout and design of various lamps and equipment.
LED point light source is idealized as mass point light source. Point light source is an abstract physical concept, in order to simplify the study of physical problems. Just like the usual smooth plane, particle, no air resistance, point light source does not exist in reality. It refers to the light source that emits light uniformly from a point to the surrounding space.
