Q:How to scientifically maintain the light bulb of projection lamp and prolong the service life?

The bulb of the projection lamp is maintained as follows:1, according to the procedures of the normal switch machine, switch machine interval is generally greater than 5 minutes;2, the use of the process should not frequent power outages, as far as possible to ensure that the work process of power supply reliability;3, each work time is best not more than 4 hours, in the process of using a larger time interval, it is best to shut down for some time;4, the use of ambient light is not too bright, reflecting the brightness of the projector will lead to an increase in the bulb;5, as much as possible the power of identity, the nominal value of the power voltage, grounding and polarity, and matching the projector.

Q:What materials do you need to make star projection lights?

Q:The most famous manufacturer of projection lamps

Its color recovery performance is good, can bring a good user experience, try to understand.

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.
