The invention discloses a bedroom bedside lamp. The bedroom bedside lamp comprises a strip-shaped lamp box inside provided with a light source. The light source is covered by a liquid box. Light transmitting liquid and light shielding liquid are arranged in the liquid box. The density of the light transmitting liquid is greater than that of the light shielding liquid. The light transmitting liquid and the light shielding liquid cannot be mutually dissolved. The lamp box is provided with a rotating shaft and rotates around the rotating shaft. Limiting devices are arranged at the two sides of the rotating shaft. When the bedroom bedside lamp is in use, a user pulls one end of the lamp box downward, so that the other end of the lamp box goes up and the two liquids in the liquid box begin to flow. Since the density of the light transmitting liquid is greater than that of the light shielding liquid, the light transmitting liquid flows to the lower end while the light shielding liquid flows to the upper end. In this way, lamp light of the lower end penetrates through the light transmitting liquid lamp light of the upper end is shielded by the light shielding liquid. In the pulling process, the flowing of the liquids of high density and the liquid of low density seems like the flowing of the liquids carrying with light lamp, so that a light and color flowing effect is achieved and external interest is brought to life.
