STANDARD LED DEVICES

DIP LED

DIP LED diodes are traditional through-hole light-emitting devices widely used in applications that require high brightness, robustness, and long operational lifetime. With a classic dual in-line package structure, these LEDs are mounted directly onto PCB boards, ensuring strong mechanical stability and reliable electrical connections. They are commonly used in indicator lights, traffic signals, outdoor displays, and signage, where high visibility, wide viewing angles, and durability under harsh environments are essential.

SMD LED

SMD LED diodes are widely used solid-state light sources designed for surface mounting directly onto PCB boards. They are available in various package sizes such as 2835, 3528, and 5050, offering flexibility in brightness, power consumption, and application design. Compared to traditional through-hole LEDs, SMD LEDs feature a compact structure, excellent heat dissipation, and uniform light output, making them ideal for LED strips, general lighting, backlighting, signage, and automotive applications.

CSP LED

CSP LED diodes are advanced solid-state light sources in which the LED chip is packaged at nearly the same size as the die itself, eliminating the need for traditional lead frames or bulky housings. This ultra-compact design enables higher packing density, lower thermal resistance, and improved optical efficiency. CSP LEDs are widely used in high-end applications such as automotive lighting, flash modules, backlighting, and miniaturized lighting systems where high brightness, precise light control, and space optimization are critical.

High Power LED

High Power LED diodes are high-intensity light sources designed to operate at higher drive currents, delivering superior brightness and luminous efficacy compared to standard LEDs. Typically built with robust thermal structures, these LEDs are widely used in applications such as street lighting, industrial lighting, automotive headlights, stage lighting, and outdoor floodlighting. Their ability to provide high lumen output, stable performance, and long lifespan makes them essential for demanding environments where efficiency and reliability are critical.

UV LED Device

UV LED devices are semiconductor light sources that emit ultraviolet radiation, typically covering wavelength ranges from 200 nm to 400 nm, including UVA (315–400 nm), UVB (280–315 nm), and UVC (200–280 nm). These devices are widely used in applications such as sterilization and disinfection, UV curing, fluorescence detection, water and air purification, and medical phototherapy. Compared with conventional UV lamps, UV LED devices offer compact size, instant on/off capability, precise wavelength targeting, and mercury-free environmental safety.

IR LED Device

IR LED devices are semiconductor emitters that generate infrared radiation, typically within the wavelength range of 700 nm to 1000+ nm, with common bands such as 730 nm, 850 nm, and 940 nm. These devices are widely used in applications including remote control systems, security and surveillance (CCTV/night vision), optical sensors, biometric recognition, industrial automation, and communication systems. IR LEDs offer advantages such as low power consumption, fast response time, compact size, and stable spectral output.

Flashing & Pixel LED

Flashing and Pixel LEDs combine integrated control functions with reliable LED packaging for blinking, color-changing, and individually controllable lighting. Available in both DIP through-hole and SMD surface-mount package formats, they are widely used in indicators, decorative lighting, signage, displays, toys, and smart lighting applications.

Traffic Signal LED

Traffic Signal LEDs are high-reliability light sources specifically engineered for road signaling systems, including traffic lights, pedestrian signals, railway indicators, and warning beacons. Designed to meet strict visibility and safety requirements, these LEDs provide high luminous intensity, excellent color consistency, and wide viewing angles to ensure clear signal recognition under various environmental conditions. Compared with traditional light sources, LED-based traffic signals offer significantly longer service life, lower energy consumption, and reduced maintenance costs, making them the standard solution for modern traffic infrastructure.

Automotive LED

Automotive-Grade LEDs are high-reliability light sources specifically engineered for vehicle lighting and signaling applications, including headlights, daytime running lights (DRL), brake lights, turn signals, interior lighting, and ambient systems. These LEDs are designed to operate under extreme conditions such as high temperature, vibration, humidity, and long duty cycles, while maintaining stable optical and electrical performance. With high brightness, precise color control, and long service life, automotive LEDs are essential components in modern vehicle safety and design systems.

Phototherapy LED

Phototherapy LED diodes are specialized light sources designed to deliver precise wavelengths for medical and therapeutic applications, such as neonatal jaundice treatment, dermatology (e.g., acne and skin rejuvenation), pain relief, and wound healing. These LEDs typically operate in specific spectral ranges such as blue (around 460–470 nm), red (620–660 nm), and near-infrared (800–900 nm), where controlled light exposure can produce clinically beneficial effects. Compared with conventional light sources, phototherapy LEDs offer advantages including narrow wavelength control, low heat generation, long lifespan, and stable output, making them ideal for safe and effective medical use.

Biological & Growlight LED

Sensor and Detector

Sensor and Detector LED diodes are specialized emitters designed to work in conjunction with photodiodes, phototransistors, or integrated sensors for detection, measurement, and control systems. These LEDs operate across both visible and infrared wavelength ranges, typically including visible red (around 620–660 nm) for alignment and indication, and near-infrared bands such as 730 nm, 850 nm, and 940 nm, which are widely used for invisible sensing applications. The selection of wavelength is critical to match detector sensitivity and optimize signal accuracy, penetration capability, and ambient light immunity. They are commonly used in proximity sensing, optical switches, encoders, smoke detectors, medical diagnostics, and industrial automation systems.

Outdoor LED

Outdoor LED diodes are high-durability light sources specifically engineered for exterior applications exposed to harsh environmental conditions. They are widely used in outdoor lighting, signage, landscape illumination, architectural lighting, and public infrastructure. Designed to deliver high brightness, strong weather resistance, and long service life, these LEDs maintain stable optical performance under challenges such as UV exposure, humidity, temperature fluctuations, and dust. Their wide viewing angles and high visibility ensure reliable performance in both daytime and nighttime environments.
