How to calculate the projection distance of LED projector

2021-08-05

Generally, the LED projection lamp commonly used in landscape lighting will choose the appropriate wattage according to the different projection distance. In addition, the projection distance of different types of projection lamps is also different. So how to calculate the projection distance of LED projector?
 
 
Generally speaking, the illumination distance has a great relationship with the illumination angle. The smaller the angle, the more concentrated the light is, and the farther the illumination distance is. The power can roughly judge the brightness of the lamp. It is estimated that the high-power 60 degree angle of the general 24W can shine about 15m, and the 30 degree angle can shine 20 meters away, and the spotlight with the reflector can find more than 30m.
 
 
 
The lighting distance of 10W landscape projection lamp is about 2m, that of 20W is about 4m, that of 30W is about 6m, and that of 50W is about 8m-10m; if it is necessary to reach the height of tree crown, it is suggested to use the highest wattage point. Calculated luminous efficiency = the higher the lumen / watt luminous efficiency value is, the stronger the ability of the luminaire to convert the electric energy into the luminous energy is, that is to say, the more energy-saving the luminaire is under the condition of providing the same brightness.
 
 
 
Under the same power, the stronger the illuminance of the luminaire, that is, the greater the brightness. The higher the building is, the more powerful the floodlights are. At present, 1W high-power LED is basically selected as the common LED floodlight in the market, and a few companies choose 3W or higher power LED according to the light flux of a single 1W because of good heat dissipation technology.
