A lamp projecting a starry sky is provided. The lamp projecting the starry sky includes at least one beam generator, a reflecting member with uneven and irregular reflecting surface, a first motor, and at least one first lens. The first motor is connected to the reflecting member through a connecting shaft, the reflecting member is driven to rotate when the first motor rotates, a light beam generated by the beam generator irradiates onto a first side of the reflecting member along an incident light path, and a light beam emitted from the reflecting member forms a moving and layering nebula projection after passing through the at least one first lens. In the lamp, after passing from the reflecting member, the light beam is magnified by the lens, so that the generated starry sky will not be too bright and dazzling, which effectively enhances the layering sense of the starry sky.

An educational monument, comprising a designated geographical area accessible to a general public, a first structure having a first face positioned to receive a solar light beam, an aperture formed through the first structure for projecting the light beam at predetermined times and, a second structure positioned to receive the light beam at a first predetermined time. A third structure positioned to receive the light beam at a second predetermined time. Wherein a transition of the light beam reflects a change in the seasons and an alignment of Earth illustrating a physical representation of the transition at a plurality of successive predetermined times, each respective predetermined time being the same hour on a different day. Wherein a plurality of ellipses are scaled from the receiving wall, accurately representing the scaled orbit of the planets.

An LED driver circuit capable of overcoming the issues in that a brightness change is perceived as a stepped change in a very low light amount region or light abruptly goes out by using PWM control and of realizing smooth dimming even at a very low amount of light is provided. In the LED driver circuit, a first circuit including a first resistor and a first power transistor connected in series and a second circuit including a second resistor and a second power transistor connected in series are connected in parallel with each other and are connected to an LED. First and second PWM signal generator circuits drive the first and second power transistors, respectively. When the first and second power transistors are in an on-state, currents flow through the LED via the first and second resistors, respectively, which enable a smooth brightness change even in a low illuminance region.

The present invention relates to collection of water after being exposed to the moonlight. The water resource for exposure under moonlight over any period of time and the storage of such collected water so obtained from any resource. The water resource collected and composed of but not limited to collection of water from resources like river, spring, rain, snow, well water, tap water, distilled bottled water, that is accumulated. The period during which water is exposed to the moonlight can have a combination of significance but not limited to: zodiac, religious, astronomical, calendar, astrological, numerology etc. Further, the exposed water obtained is packed and labeled based on the religious, astronomical, astrological, numerological significance classified or falling under the time when the water resource or the water stored in the container is exposed to the source of moonlight. The water resource collected and composed of but not limited to collection of water from resources like river, spring, rain, snow, tap water, dew, distilled bottled water, well water that is accumulated or placed.
