1. The basic definition of LED flood light: LED flood light is also called projection light, spot light, flood light, etc. It is mainly used for architectural decoration lighting (currently it has not yet reached the function of lighting), and its appearance There are round and square ones, because heat dissipation generally has to be considered, so there are still some differences between their appearance and traditional floodlights.
2. The basic parameters of LED flood light: The commonly used LED flood light on the market is basically a 1W high-power LED tube (each LED tube will have a high-efficiency lens made of PMMA, and its main function is two The light emitted by the LED tube is distributed twice), and a few companies have selected 3W or higher power LED tubes because of the good heat dissipation technology. At present, I have learned about 1W, 3W, 8W, 12W, 18W, 36W and other power forms, because a heat dissipation factor must be considered, each high-power LED flood light will be equipped with a heat sink (usually made of aluminum). The size of the heat sink depends on the power of the LED tube. , This more or less brings some inconvenience to the shape design of LED flood light. Throughout the whole industry, it is affected by many factors such as price, light efficiency and national awareness. The application is not very wide, but this situation is slowly changing. Many domestic projects (such as the lighting of both sides of the Pearl River, the lighting project of Xiamen Zhongshan Road, etc.) have applied high-power LED floodlights.
3. LED flood light control form: LED flood light has two control methods: external control and internal control. The internal control does not require an external controller and can be built in a variety of change modes (up to six), and the external control needs to be configured with external control The color change can only be realized by the controller. At present, most of the applications on the market are external control.
Fourth, the main application occasions and achievable effects: LED floodlights are controlled by a built-in microchip. In small engineering applications, they can be used without a controller, and can achieve gradual changes, jumps, color flashes, random flashes, and gradual changes. Dynamic effects such as alternation can also be controlled by DMX to achieve effects such as chasing and scanning. At present, the main application fields are: exterior wall lighting of single buildings and historical buildings; interior and exterior lighting of buildings, indoor local lighting; green landscape lighting, billboard lighting; lighting for special facilities such as medical treatment and culture; bars, dance halls, etc. With the continuous development of LED technology, atmosphere lighting in entertainment venues, etc., it is believed that one day it will be able to replace traditional floodlights.
