Disaster Prevention Supplies Generator-powered LED Light Night Star JP

basic information

●【No Batteries or Bulbs Needed】 Maintenance-free with no need for batteries or bulbs. Thanks to the magnetic power generation system and 50,000-hour durable LED, there are virtually no consumables required. Even after years of being "left alone," it will light up with just a shake. ●【Charge by Shaking】 Power is generated by moving a magnet back and forth within a coil inside the main body. Shaking causes the magnet to move, generating current that charges a capacitor (charge and discharge component). This is converted into light by an LED (light-emitting diode), and the light is efficiently focused and projected by a concave mirror and convex lens. ●【Shock-Resistant Design】 Made with a fully integrated polycarbonate structure, it is extremely sturdy and lightweight. ●【Temperature-Resistant Design】 Achieves a lighting temperature range of -40℃ to 55℃. It can be charged and lit in various expected scenarios. It will light up even if the surface is frozen. ●【Waterproof Design】 The Night Star JP is completely waterproof (up to 100m depth). Even if it accidentally falls into water during floods or heavy rain, it will float with the light-emitting surface facing up. It will not rust even when submerged in seawater. ●【Non-Contact Switch】 Prevents accidental ignition ●【Glow-in-the-Dark Switch】 Responds to sudden darkness

Applications/Examples of results

**Strengths of Capacitors (Condensers)** Generally, rechargeable batteries become unusable when fully discharged, so they need to be used (charged) regularly. The capacitors used in NightStar JP differ from rechargeable batteries that "generate electricity through chemical reactions"; instead, they serve the role of "storing the generated electricity as is" (referred to as electric charge). Since there are no elements that cause degradation, they can theoretically be used semi-permanently, ensuring that the generated electricity can always be utilized when needed. NightStar JP is equipped with a mechanism that reliably stores energy and supplies light, even after being left unused for years. **Mechanism of Power Generation and Emission of Light** NightStar JP applies Faraday's law (electromagnetic induction) to generate electricity by moving a magnet back and forth within a coil. This electricity is charged into the aforementioned high-performance capacitor (charge and discharge component) located at the front of the main unit, which converts it into light using energy-efficient LEDs (light-emitting diodes). The light is then focused and projected without waste using a concave mirror and a convex lens. Since repelling magnets are installed at both ends of the tube, there is no collision of the reciprocating magnets, resulting in quiet operation. The design minimizes energy loss to the greatest extent.

Detailed information

• 

  [No batteries or light bulbs needed] The Night Star JP is maintenance-free and does not require batteries. Thanks to its magnetic power generation system and LED, there are essentially no consumables needed. Even after years of being left untouched, it will light up with just a shake. It continues to illuminate the darkness without running out, even in cases of long-term and extensive use.

• 

  "Charge by shaking" It generates electricity by moving a magnet back and forth within a coil inside the main unit. By shaking, the magnet moves back and forth, generating current that charges a capacitor (charge and discharge component). The energy is converted into light by an LED (light-emitting diode), which is then focused and emitted efficiently by a concave mirror and a convex lens.

• 

  【Shock-resistant design】It will function normally even after being dropped from a height of 1.2 meters onto concrete. The fully integrated polycarbonate structure is extremely sturdy and lightweight.

• 

  [Temperature Design] Achieves a lighting temperature range of -40℃ to 55℃. It can be charged and lit in various anticipated scenarios. It will light up even if the surface is frozen. It can be used in the extreme cold of Antarctica.

• 

  [Waterproof Design] The Night Star JP is completely waterproof (up to 100m depth). Even if you accidentally drop it into the water during a flood or heavy rain and panic, it will float with the light-emitting surface facing up. It is not only useful for disaster prevention but also very convenient for use on boats and fishing. Nighttime work on rainy days is not a problem. It does not rust even when submerged in seawater.

• 

  It uses a non-contact switch, eliminating the risk of sparks caused by metal contact. It prevents gas leaks from earthquakes and spark-induced explosions from gasoline during vehicle inspections. You can safely turn on the switch, preventing secondary disasters.

• 

  Adopting a glow-in-the-dark switch that illuminates in the dark. It responds to sudden power outages. Since it is located on the switch part, operation is straightforward, allowing for quick use.

• 

  Nightstar JP is manufactured one by one with meticulous work at a Japanese factory specializing in precision equipment manufacturing, in order to maintain its overwhelming performance, quality, and reliability. From the mounting of the circuit board to the winding of the coils, magnetic force inspection of the magnets, UV bonding of the lenses and switch components, etc. After going through a manufacturing process without any compromises, only products that have passed numerous strict inspections, including electrical tests, airtightness tests, and visual checks, are shipped.
