Q:What is the relationship between the power of projection lamp and luminous flux and luminous efficiency?

Start with a formula: light effect = total luminous flux / bulb power. From this formula, we can see that the higher the luminous efficiency is, the stronger the ability of the lighting equipment to convert electric energy into light energy, that is, the higher the light efficiency is, the more energy saving.At the same time, the above formula is deformed: total luminous flux = bulb power * luminous efficiency. That is, under the same power, the higher the light value, the greater the brightness.If some businesses only promote their projection lamp power is relatively large, but the light effect is relatively low, so the relative brightness is relatively small, which is why we have the same brightness power products from different manufacturers is not strengthConsistent cause. Therefore, customers in the purchase of recommended projector products, but also pay attention to light efficiency of this parameter.
