Light bulbs have become a staple in modern technology. Ever since they were invented, the candle and sunlight were no longer the main methods of brightening up a room.
Their uses are extremely valuable, and as a result, we see them constantly. However, bulbs run a very small but important risk – they explode.
For a multitude of reasons, bulbs can explode, and when they do, they can become problematic.
Projector’s use bulbs in a unique way to show images on a screen (essentially, projectors project). Due to their entwined use, projector health and bulb health are really important for anyone using them.
So, why does a bulb explode anyway? And what does the projector have to do with any of that?
Well, these rhetorical questions do actually have answers.
Let’s dive into the potential issues that arise with the use of projects and bulbs, and try to work out the best environment for both of them to work in harmony.
What would cause a bulb to explode?
With any piece of technology, there is always the potential for a malfunction or failure.
Lightbulbs are, of course, no different, and a bulb could potentially explode for a multitude of reasons.
Faulty design and cheap material can be a factor, but assuming the bulb is made perfect, there are still some things that can cause explosions.
Incorrect Wattage – putting in a lightbulb that is, for example, 75W, in a circuit only for 50W, the circuit will attempt to adjust for the increase in wattage. When this happens, it increases the risk of the bulb exploding because of the increase in current.
Depending on the wattage, a bulb typically can’t handle this increase of current for very long. Additional current for a long period of time will cause a bulb to explode.
Not Tight Enough – if a bulb is incorrectly placed into a fixture, then it can increase the risk of the bulb exploding.
Without a close connection, the electrons have to make a large jump between the fixture and the bulb in order to light it. This jump generates a lot of heat, which in turn can cause a bulb to explode.
The good news is that this is easily avoided by just making sure that your bulbs are properly and tightly screwed into place.
Oil From Hand Contact – one of the lesser known ways a bulb explodes, oil from the skin of your hands can actually increase the risk. Halogen bulbs especially are prone to this, because of how the bulb is designed.
All human skin naturally produces oil, which, when coming in contact with the bulb, leaves a residue that can become overheated.
The spots where you touch your bulbs can become overheated, and in turn, explode. Wearing gloves when you replace your bulbs or making sure to wash your hands before can negate this.
Is it dangerous if a projector lamp bulb exploded?
Of course it is! A bulb that explodes can send hot material scattering in random directions.
Hot glass especially is dangerous. Other parts of the bulb too can be sent flying.
Cleaning up after this mess can also lead to injury, with glass especially needing extreme care to clean up.
While it can’t be controlled where you are in relation to the bulb when it explodes, the aftermath needs to be treated seriously, or else there could be consequences.
Is it normal for a projector to get hot?
Nearly all forms of technology can get hot after prolonged use. Projectors are no different, and could heat up rather quickly, due to the high power they need to function.
However, projectors are built to withstand this pressure, so as long as there is a proper airflow, this shouldn’t be too big of a concern.
Heating problems are extremely common, so taking the right precautions takes some of the pressure off the projector.
How do I stop my projector from overheating?
Airflow is needed to cool the projector down; without it, a projector can quickly burn itself out and shut off.
As long as there is nothing blowing a projector’s fans, it is self-sufficient and can cool itself off. Having a clean environment to avoid this is extremely beneficial.
To speak more on the fans inside the projector, it may also be in your best interest to make sure these fans are clean and work properly.
Cleaning them may be occasionally necessary, to stop any dust or other sort of dirt from blocking them.
Not leaving the projector on for extremely long periods of time, and giving it time to cool off in between uses, is also better for the health of the projector.
How long can a projector run continuously?
This can change a lot based on the type of projector, as well as the precautions you take to stop it from potentially burning out.
Assuming the conditions are fine for the projector, it can stay running for several hours continuously, before needing a short break.
Projector bulbs have a certain life span – often called a “bulb life” or a “lamp life,” it’s expected for the bulbs to eventually die out after a certain amount of hours.
Depending on the projector, this can range from 1000 hours of use, to some projectors which claim to get up to 5000 hours of use.
As long as you can replace the bulb, it shouldn’t be too big of a concern – but obviously, it is healthier for the projector to be treated with care.
