Product Description: Shenzhen Langte TechnologyHigh-Efficiency Radar Light Tube Product IntroductionIn the field of underground garage lighting, Shenzhen Langte Technology's high-efficiency radar light tube stands out with its exceptional performance, making it an ideal replacement for traditional 40W fluorescent lamps. This light tube, model LT-T8-120-8W, has a power consumption of only 8W while delivering efficient illumination, significantly reducing energy consumption compared to traditional tubes.I. SpecificationsLuminous Efficacy: With a luminous efficacy of up to 180lm/W, it emits 180 lumens of luminous flux per watt of electricity consumed. Compared to ordinary light tubes (with an efficacy of about 100lm/W), it provides brighter illumination at the same power level, effectively enhancing the garage's lighting level.Dimensions: The tube diameter follows the common T8 specification, approximately 26mm, with a length of 1200mm. This design allows it to fit most garage lighting fixtures, facilitating direct replacement and retrofitting while reducing installation difficulty and cost.Input Voltage and Frequency: Supports a wide voltage input range of AC185–265V, adapting to grid voltage fluctuations in different regions and settings to ensure stable operation. The power frequency is 50/60Hz, compatible with common mains frequencies. LED Chips and Related Parameters: Utilizes high-brightness, high-efficiency LED chips, with the specific quantity depending on the design. The chips offer excellent luminous performance and strong stability, ensuring high luminous efficacy and long service life. The color rendering index (CRI) is generally ≥70, accurately reproducing object colors to help drivers identify vehicles and surroundings in the garage. The common color temperature is 6000–6500K cool white light, providing bright and clear illumination to enhance garage visibility and ensure driving and pedestrian safety.Service Life and Operating Temperature: Designed for a long service life of over 50,000 hours. With daily use of 10 hours, it can operate continuously for over 13 years, greatly reducing the frequency of replacements and maintenance costs. The operating temperature range is -20°C to 45°C, allowing it to adapt to seasonal and environmental temperature changes in garages, ensuring reliable operation in both cold winters and hot summers.II. PrinciplesLight Emission Principle: The core of the LED chips inside the tube consists of a PN junction made of semiconductor materials. When current passes through the LED chips, electrons and holes recombine at the PN junction, releasing energy in the form of photons to produce light. The high electro-optical conversion efficiency of LED chips means most electrical energy is directly converted into light energy, minimizing heat loss, which is a key factor in its high luminous efficacy.Radar Sensing Principle: The tube is equipped with a built-in millimeter-wave radar sensor that operates based on the Doppler effect. The radar sensor continuously emits high-frequency microwave signals and receives reflected signals. When a vehicle or pedestrian enters the radar sensing area, the movement of the target object causes a change in the frequency of the reflected signal. The sensor detects this frequency change, processes it through an intelligent recognition circuit, and transmits the signal to the lamp's driver circuit, prompting the tube to quickly switch from low-power sleep mode to full-power operation for automatic illumination. After the target object leaves the sensing area, the tube automatically returns to low-power sleep mode after a delay of 15–60 seconds (adjustable as needed), saving energy.III. Product DetailsHousing Material: Made of high-quality aluminum alloy for the tube housing. Aluminum alloy offers excellent heat dissipation, quickly dissipating heat generated by the LED chips during operation, effectively lowering the chip temperature and extending the service life of both the chips and the entire tube. Additionally, aluminum alloy is lightweight, facilitating installation and maintenance, and provides sufficient strength to protect internal electronic components from physical damage.LED Chips and Substrate: Features a full aluminum substrate design, with LED chips directly soldered onto the aluminum substrate. The aluminum substrate has excellent thermal conductivity, rapidly transferring heat from the chips to the aluminum alloy housing, further enhancing heat dissipation. Compared to traditional substrates like fiberglass boards, this design ensures the chips operate in a stable temperature environment, improving the lamp's reliability and luminous efficacy stability.Driver Power Supply: The driver is a critical component of the light tube, responsible for converting input AC power into DC power suitable for LED chip operation while stabilizing current and voltage output. The product uses a high-quality constant-current driver with multiple protection features, including over-current, over-voltage, and short-circuit protection, effectively preventing power supply failures from damaging the chips and ensuring safe and stable operation. The high-efficiency design of the driver also contributes to improved energy utilization and reduced power consumption.Lens Design: To achieve better light distribution and illumination effects, the tube is equipped with a specially designed lens. Made of high-transmittance optical material, the lens's shape and angle are meticulously engineered to evenly scatter and refract light emitted by the LED chips, providing wider and more uniform coverage while minimizing dark spots, creating a bright and comfortable lighting environment for the garage.Installation Methods: The tube supports various common installation methods, such as traditional T8 lamp holder installation, allowing direct replacement of existing T8 fluorescent tubes without extensive fixture modifications, making installation simple and convenient. Additionally, suspension or wall-mounted installation options are available to meet the lighting layout requirements of different garage spaces. Outer Packaging: Uses corrugated cardboard boxes for outer packaging. The boxes offer sufficient strength and compression resistance, capable of withstanding certain levels of squeezing and impact to protect the tubes during transportation and storage.In summary, Shenzhen Langte Technology's high-efficiency radar light tube, with its outstanding specifications, advanced working principles, and meticulous product details, offers significant advantages in garage lighting energy-saving retrofits. It not only provides high-quality illumination for garages but also substantially reduces energy consumption and maintenance costs, making it the optimal choice for upgrading underground garage lighting.
