Looks as if it's a Jinbei:

I never used a ring flash. Does the ring light source really have to surround the lens? I am thinking about using a beauty dish with a circle-shaped mask in the center to simulate the effect.

It does need to surround the lens to be a ring flash.
A beauty dish is going to give you a different look because you can't get it that close to the lens.

Thanks. It looks like the ring flash needs to be close to subject; otherwise, it's acting like a point light source.
It's a ringflash, initially judging by the casing it looks like an Elinchrom or Hensel ringflash, but those two lights (red and white) make me think otherwise.

As mentioned above, yes, it has to surround the lens. If it doesn't, it's not a ring flash.

Well, you may get a "ringlight-like" catch light in the subject's eyes (if you're photographing a person), but it won't be dead-center in the eyes like the reflection of a true ring light would be.
The other characteristic of a ring light -- the shadowless effect caused by the light coming equally from all side of the lens axis -- won't be recreated by using a dish with a mask, because the dish cannot encircle the lens. The light will be off axis to one degree or another.
To get that effect without a ring light, you would need to set up multiple lights an all sides of the camera, all firing at equal intensity. A ring light is simpler, both in setup and in syncing.

An on axis point source...which may be just what's wanted under some circumstances.
It's a Lumedyne Ring Flash - essentially the same model used by Hensel and Elinchrom. Not sure who actually makes it. The Lumedyne has the charging and flash ready lights.
