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 LEDs, there are essentially no consumables required. Even after years of being "left alone," it will definitely light up when shaken. ●【Charge by shaking】 Electricity is generated by moving a magnet back and forth within a coil inside the main unit. Shaking causes the magnet to move, generating current that charges a capacitor (charge/discharge component). This is converted into light by an LED (light-emitting diode), and the light is efficiently focused and emitted 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 still light up even if the surface is frozen. ●【Waterproof design】 The Night Star JP is completely waterproof (up to 100m depth). Even if accidentally dropped into water during floods or heavy rain, it will float with the light-emitting surface facing up. It does 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** Common rechargeable batteries become unusable when fully discharged, requiring regular use (charging). 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" (known as charge). With no elements that cause degradation, they can theoretically be used semi-permanently, ensuring that the generated electricity can be utilized when needed. NightStar JP is equipped with a mechanism that reliably stores energy and provides light, even after being left unused for years. **Mechanism of Power Generation and Emission** 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 (charging and discharging component) located at the front of the unit, and is converted into light by energy-efficient LEDs (light-emitting diodes), which are then focused and emitted without waste using a concave mirror and convex lens. The ends of the tube are equipped with repelling magnets, preventing collisions of the reciprocating magnet and ensuring quiet operation. The design minimizes energy loss to the greatest extent possible.

Detailed information

• 

  [No batteries or bulbs required] 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 when shaken. It continues to illuminate the darkness without running out, even in cases of long-term and extensive use.

• 

  "Charge by shaking" The device generates electricity by moving a magnet back and forth within a coil inside the main body. By shaking, the magnet moves back and forth, generating current that charges a capacitor (a charge and discharge component). The energy is converted into light by an LED (light-emitting diode), which is considered to have the highest energy efficiency, and that light is focused and emitted without waste by a concave mirror and a convex lens.

• 

  【Shock-resistant design】It can remain lit even after falling from a height of 1.2 meters onto concrete. Its fully integrated polycarbonate structure makes it very sturdy and lightweight.

• 

  [Temperature Resistance 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 when 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 100 meters deep). Even if you accidentally drop it into the water during a flood or heavy rain, it will float with the light-emitting surface facing up without any issues. 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 occurrence of sparks due to 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 coil, magnetic force inspection of the magnets, UV bonding of the lens 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 confirmations, are shipped.
