Projection photographic lamp

Many times, when you buy projection lamp products, you will be asked about their power, lumen and luminous flux. Due to the different power of different models, their lumens and luminous flux are also different. Today, Le Di Optoelectronics will give you a simple answer to these data.

The higher the light efficiency value, the more energy saving.

The higher the luminous efficacy value, the stronger the ability of lighting equipment to convert electric energy into light energy, that is, under the same brightness, the higher the luminous efficacy value, the more energy-saving it is.

The higher the luminous efficiency value, the greater the brightness.

Under the same power, the higher the light efficiency value, the greater the brightness.

Luminance value affects brightness.

If some merchants only advertise that their projector lamp power is relatively high, but the light efficiency is relatively low, then the brightness is relatively small, which is why the brightness of products with the same power from different manufacturers is not necessarily the same.

The light efficiency value needs attention.

Customers should also pay attention to the parameter of light efficiency when purchasing the recommended projection lamp products. Only when the power is high and the light efficiency is high, the brightness is large.

Light Efficiency Value of Le Di Photoelectricity

Take our company as an example, the luminous efficiency of the LED lamp bead of projection lamp is100-110lm/w, and the luminous efficiency of the metal halide lamp bulb is relatively low, only 50-90lm/w. ..
