Application status and prospects of new energy products LED street lights
The LED light source, an important component of which is a light emitting diode, is a solid-state semiconductor device that can convert electrical energy into visible light. Compared with ordinary light sources, LED light sources have many advantages. They are changeable and can use the principle of red, green and blue to form different light color combinations. At the same time, they can be used flexibly. Products in various forms of dots, lines and surfaces are extremely controllable. Convenient, as long as you adjust the current, you can adjust the light at will.
The performance of the LED light source is reliable, and its half-life (that is, the time for the light output to decrease to half of the initial value) is about 10,000 to 100,000 hours. At the same time, its brightness has a huge room for expansion. Like computer technology, the development of LED follows Moore's Law, and its brightness will double every 18 months. Therefore, LED light sources have become the first choice for machine vision system integrators and equipment manufacturers.
Machine vision LED light source has the advantages of long service life, adjustable brightness, low temperature, balance, stability, no flicker, no shadow, consistent brightness and color temperature, etc., which meets the technical requirements of machine vision users for high quality and high precision. However, in the production and application of LED light sources, a series of issues need to be paid attention to in order to better exert its performance advantages, that is, how to achieve high light efficiency, achieve high color rendering, improve reliability, and reduce costs.
With the development of the current solar street lighting industry, the spectral distribution of LED white light is similar to that of sunlight. It is necessary to fully consider visual comfort, humanized lighting, etc., and implement intelligent dimming control to reduce power consumption and improve energy saving effects. Enabling semiconductor lighting to truly provide people with an energy-saving, environmentally friendly, healthy and comfortable lighting environment, regardless of the status quo, and constantly develop new application areas.
