The LED flood light technology

I. Definitions: LED floodlight called lights, spotlights, floodlights, etc., is mainly used for architectural lighting purposes) which has a circular shape also square, as heat generally have to be considered The reason, so its shape and the traditional spotlights still have some differences.

Second, the parameters: Currently commonly used LED floodlights on the market are basically 1W high-power LED tubes (each LED tube will have a high-efficiency lens made of PMMA, its main function is to distribute the LED tube twice) The light), there are a few companies because of the heat treatment technology, and the choice of 3W or higher power LED tube, currently, mainly 1W, 3W, 8W, 12W, 18W, 36W, etc.. Power form, because both Considering a heat dissipation factor, each high-power LED floodlight 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.

Third, the control form: LED flood light has two control modes: external control and internal control. The internal control can be built with multiple change modes without external controller (up to six types), while external control must be configured with external control controller. To achieve color change, the current application on the market is still dominated by external control.

Fourth, the main application and achievable effects: LED floodlights through the control of the built-in microchip, in small engineering applications, can be used without controller, can achieve gradient, jump, color flicker, random flicker, gradient Alternate dynamic effects, such as chasing, scanning, etc. can also be achieved through DMX control. At present, the main application fields are all: single building, historical building group exterior wall lighting. The building is exposed to light and indoor lighting. Green landscape lighting, billboard lighting. Specialized lighting for medical and cultural facilities. Bars, dance halls and other entertainment venues, etc., with the continuous development of LED technology, I believe that one day can replace the traditional spotlights.
