This is a super high-brightness LED bar with a narrow width of 6mm, used as a light source for the light input surface of a light guide plate. (Principle of thin light guide plate advertising) - Light is introduced from the frame part of the thin advertisement → into the light guide plate using an LED aluminum bar → guiding light to the light guide plate on the back of the advertisement → the light guide plate backlights the screen. (Cautions for use) - Due to the high current value, the lighting length of a single aluminum bar is limited to 1 meter. (Terminology) - SMD: (Surface Mount Device, a block of surface-mounted components on a circuit board) here refers to the commonly known caramel-shaped automatic soldering LED, measured in millimeters.

(Product Description) - Based on moisture and external temperature, the snow sensor determines whether the moisture adhered to its surface is rain or snow, activates a relay to operate devices such as snow melting systems, and outputs a detection signal externally (this model outputs a relay signal and RS485 external signal: wiring diagram available). - The capacitive rain and snow sensor is based on the reflection principle in the frequency domain, utilizing high-frequency electronic technology, and can measure with high sensitivity whether it is raining or snowing (capacitive detection diagram available). - The sensor incorporates a capacitor, thermometer, IC, and heater. - The moisture adhered to the sensor surface is detected by the potential difference of the capacitor, and the IC determines whether the moisture is rain or snow based on moisture and external temperature, activating the relay and outputting a detection signal externally. - After detecting rain or snow, moisture remains on the surface, so the sensor surface is dried with a heater to prepare for the next normal detection.

(Custom Products) - DC output voltage: In addition to 12V and 5V, we can also produce 4.2V/3.3V, 24V, and adjustable power supplies. - Output wire: If no specifications are provided, we use all-copper black parallel wire. Other options include changing wire length, white wire, round wire, braided wire, and coil wire. - With output terminals: Terminals can be customized (for example, for an additional cost of about 50 yen per unit, we can change from a male DC terminal to a male micro USB or SM2 pin terminal, etc.). - Without output terminals: We can process the wire by cutting one end only (it can be cut to any desired length) or provide custom wires with approximately 3mm of insulation stripped for easy soldering. - Stabilized power supply: Switching power supplies can be pulse-adjusted to focus on either constant current, constant voltage, or constant power depending on the application. In particular, for charging constant voltage power supplies, if we receive the voltage characteristic data of the battery to be charged, we can design the voltage to facilitate complete charging. Please consult us separately regarding your application.

- Fast charging: An abbreviation for quick charging. It is also referred to as rapid charging, and in docomo, it is called high-speed charging, but since the abbreviation does not fit well, we have standardized it as fast charging here. Description of fast charging operation: Built-in QC/PD compatible IC charger → QC/PD cable with an additional signal line → When charging a smartphone: - When the smartphone is QC/PD compatible, the charging voltage progresses as follows: DC 12V 1.5A → 9V 2A → 5V 3A. As charging progresses, the IC control changes the charging voltage from 12V to 5V, protecting the smartphone while charging in about one hour. - When the smartphone is not QC/PD compatible, charging is possible only at 5V. Moreover, since the charger/cable is designed for high current, it can charge faster than the typical 1A charger/cable that usually comes with smartphones. Note: Caution against overheating on the smartphone side!

(Sterilization Principle) Two types of sterilization: 1. The high energy of UVC destroys the RNA of the coronavirus. 2. When the wavelength of the UV tube CCL is short, ozone O3 is generated (185nm < 220nm), and the decomposition of O2 + O: (253.7nm) occurs simultaneously. During the decomposition of ozone, the generated nascent oxygen O: has a strong oxidative power that also oxidizes the coronavirus. Main Functions: - Sterilization using UV tube CCL - 10W Qi wireless charging for smartphones Compatibility: Up to 7 inches, iPhone 8 and later / New Android models Standard Accessories: - Input QC cable: 1m long, type A-C charging data, Android QC cable, 2A 4-core Optional Parts: - Dual-port QC/PD charger with voltmeter - Dual-port QC/PD car charger with voltmeter - QC/PD cable type C-C - iPhone PD cable type C-Lightning - Qi wireless charging card (to be attached externally to the smartphone when the smartphone does not support Qi) Note: - This device can also be used with a standard 5V USB charger, but in this case, it will only accept 5V normal input and will not support QC 9V input.
