Disclosed is a bubble lamp for quasi bubble flow. A buffer made of a transparent material having an excellent heat conduction effect and impact moderating performance is configured on the top of the bulb configured on the main body of the bubble lamp or on the bottom of the glass tube configured on the upper cover, and the casing made of a transparent and no-easily-broken material is put around the glass tube, thereby abutting the glass tube against the top of the bulb across the buffer when the upper cover is covered on and coupled to the main body, allowing both the glass-made bulb and glass tube to be buffered by the butter and thus to block or decrease an impact when a contact force is too large upon assembly, and preventing the bulb or glass tube from being broken.
