Newest and smallest Green 5W projector for laser man device

[kecked]

I have to agree here. This is a really unsafe device with or without the safety board. You'd be better to do a lower wattage device like 100mw and add a fog device in the box. In fact I would sell it as a vertical laser projector for ceiling or planetarium use and let the end user misuse it. Definitively drop the laserman show name as it would allow a legal person to use it to show you knew it was to be misused or could be used in an unsafe way and you didn't do anything to stop them. That opens you up to a large loss of funds.

在这里我不得不同意。这是一个非常不安全的设备带或不带安全板。你最好做一个像100MW瓦数较低的设备， 并在框中添加雾设备。事实上，我想卖掉它作为一个垂直的激光投影机天花板或天文馆使用，并让最终用户滥用。 明确下降laserman的显示名称，因为这将使法人用它来显示你知道这是被滥用或可能以不安全的方式使用 你没有做任何事情来阻止他们。打开你到一个大的资金损失。

Copyright issues aside. From my understanding this a laser projector with the aperture on top, designed to sit on the floor, scanning upwards for 'laserman' to stand over and choreograph a dance surrounded by beams... Not wearable. As with any laser projector, the burden of safety for the show falls on the show operator.

Not my cup of tea, and perhaps I'm misunderstanding the purpose of these, but I fail to see how these are any more potentially dangerous to the audience say mounted on stage pointing upwards at the ceiling, than a conventional laser projector scanning over the audience, providing standard safety precautions are followed such as the audience is restricted from coming on stage and an emergency stop is employed with an operator watching for anyone approaching the stage.

The 'laserman' of course would need good eye / skin protection, and regardless of that would be taking a risk. I suppose the dangers to the audience would be if the 'laserman' would be using any mirrors or otherwise reflecting the beam into the audience, but again that's all up to the show operator.

I guess the potential danger lies in someone not knowing the potential dangers using it without proper protection, or proper regard for safety. But same can be said about laser projectors in general.

The gloves and hand held devices on the other hand are something that really shouldn't exist, inherently very dangerous.

My biggest question is how they are so cheap for a complete projector with 5W of green. What brand of module inside ?

Buy a Coherent Taipan 5W or Jenoptic D2.5 ; they cost over double the price but last 20 x longer.

Absolutely! But from my understanding they are way over double the cost.. Or have they come down to a more affordable level ?

This is a difficult issue. Free trade agreements have made lasers accessible to everyone on this forum (bar the few lucky people who work in the research industries).

Maybe as a forum we could help write the safety section in GoldenStar Lasers' user manual? From my experience, this is what severely lacks in all of the lasers I have purchased from China. They always state that they should be installed by a competent person, but so do the manuals for any other type of disco light. The dangers are never really stated properly.

Would it help the industry if laser user manuals stated the risks and consequences properly?

A heavy emphasis on safety in user manuals could definitely help. An education campaign in general. Sadly is not too uncommon to see lasers in night clubs misused, around here, they seem to generally be the biggest offenders. A few production companies as well, though the more reputable ones do take it seriously. Whenever I see something like that I always try to explain how to safely use their lasers, but there are some that just ignore the advice.

If it were very clearly stated in the manuals along with suggested ways to set them up safely (such as including in all projectors easy x, y adjustments to make keep beams overhead when run on sound to light or dmx, built in beam block or safety lens mounts, scanfails, etc) Unfortunately among the less reputable manufacturers, the drive to offer the lowest price, and the customers that buy them will always keep that from being a reality.

If so I misunderstood its purpose what with the fanned effect appearing to come from the man in the picture - on close inspection it appears to come from behind. That said, the picture does then raise another concern - it appears to show 2 pencil beams coming from 2 projectors in the floor (?) and these pencil beams then being reflected off gloves into the audience. Static pencil beams are even worse than the original scenario!

I really think Winni your company would be better off staying away from these type of effects or at least promoting the projectors as vertical cage style effects for dancers wearing goggles Kvant trade show style rather than promoting them for Laserman use with their reflection into the audience.

I'm afraid I'm going to have to disagree with most people here on the safety thing.
As laserists, it is our responsibility to ensure a show is safe, and given the wide range of ways we can use a laser projector (and make it unsafe!) it is unrealistic to suggest that Goldenstar should be accountable for that.
This is a very specific effect, and people wishing to do it should makwe themselves aware of the dangers.
As m0f says, the documentation included should make it very clear as to the nature of the effect and the hazard it presents, but as to any further responsibility, I think you need to let users get on with it. you cannot legislate for everything, that is why we have the controls on use in place (whether they are effective in your country or not). That to me is a separate issue.

I notice that when a laser product comes on the market, like a 4watt laser with sound-to-light, the forum shudders, knowing that there are DJs out there likely to set them up 2 meters high and at point blank range to their audience. It is the laserist's responsibility but it's also the DJs and the kids in their bedroom that have access to this stuff, often without adequate warning of the dangers.

I think the thing people on here are trying to avoid additional legislation and licensing but that may only be avoided through personal and corporate self-responsibility. It only takes one teenage lad to buy one of these or something similar, blind themselves or their friends and the whole business could change forever.

I'm not suggesting that the manufacturer should be responsible for dangerous use of a product. I am suggesting that their warnings should be adequate and proportionate to the risks involved in that product based on the recommended directions for use.
