LED spot light is also called projection light, spotlight, floodlight, etc. which is mainly used for architectural decoration lighting purposes (not yet reached functional lighting purposes), its appearance is available for round and square, because generally we have to consider the reasons of heat dissipation, therefore the appearance of led spot lighting still has some differences with the traditional spotlights.
2. LED Spotlights basic parameters
Currently the commonly used LED spotlights on the market basically use 1W high power LED tube (each LED tube has a high optical efficiency lens made of PMMA, whose main function is secondary distribution of the light emitted by the LED tube), few companies choose 3W or higher power LED tube because cooling technologies are handled well. There are 1W, 3W, 8W, 12W, 18W and 36W power forms, because all have to take cooling factor into account, therefore each high-power LED spot light will be equipped with a cooling device (aluminum is commonly used). The size of the heat sink depends on the size of the LED tube power, which more or less brings a little inconvenience to the LED spotlights shape design. Throughout the industry, affected by the price, light efficiency and universal recognition and many other factors, the application of high-power e27 led spot light is not very wide, but this situation is slowly changing, and there are a lot of engineering in the country has applied high-power LED spotlights.
3. LED spot light control form
LED spotlights have external control and internal control two control modes; the internal control doesn't need external controller, can be built-in with many change modes (up to six), and the outer control will have to configure external control controller before color change. The majority applications on the market are external control.
4. Main applications and the effect can be achieved
LED spotlights can be used without controller in minor works applications through the control of built-in microchip, to achieve a gradual transition, color flashing, random flashing, alternating gradient dynamic effects, which can also achieve scan results by DMX control chase. Currently, the main application areas are: single building, historical buildings exterior lighting, the building "inner light penetrating outside" lighting , indoor local lighting; greening landscape lighting, billboard; medical, cultural, and other specialized facilities lighting; bars, discos, etc. entertainment atmosphere, lighting, etc. As LED technology continues to evolve, it is believed that it will replace the traditional spotlights one day.
