Today, the editor will share with you what the luminous flux of the LED lens lamp is? How to calculate the light flux of LED lens? And what is the color temperature of the LED lens light?  How to calculate the color temperature of LED lens lamp?

The actual luminous flux of the LED lens lamp(Lumens)/(Single light source luminous flux*Number of light sources) , which is shalloweris the luminous flux actually emitted by the luminaire divided by the luminous flux that the luminaire should emit. For example: There are five LED lens lights1WHigh-power light source, the luminous flux of a single high-power light source is80LM, the whole light should besend80LM*5PCS=400LM But when assembled into a luminaire, the actual LED lens light flux is only350LM. This is the luminous efficiency. Then the light efficiency of this LED lens light is 350LM/400LM=87.5%

What is color temperature? Colour temperature refers to the color changes that the human eye perceives under different energies of light waves. In the calculation of color temperature, yes span>Kelvin is the unit, bold 0° Kelvin= Celsius< /span>-273 ° span>C as the starting point of the calculation . Heating the black body, As the energy increases, will enter the realm of visible light,For example,in 2800 °K , the color light emitted is the same as that of the bulb, we say that the color temperature of the bulb is 2800 °K.

The color temperature change in the visible light field, from low color temperature to high color temperature is orange-red--> span>white--> Blue. The color temperature of standard sunlight is about 5200~5500°K, photojournalistic light 3200°K, generallythe color temperature of tungsten filament lamps is about 2800°K. In LED Lens Lightsproducts,An important specification number is color temperature,this relates toLED lightingProductsThe color characteristics displayed by the product are generally All lamps also have color temperature specifications.
