Product Description of 3mm red led

3mm dip diode led view angle is 30-60 degree. It can do water clear lens or transparent lens or white diffused lens or color diffused lens. 3mm red led is widely used for indicator. Our factory has large capacity and guarantees high quality for this popular dip led.

1. Standard 625nm red light, zero color difference in batch
Using high-quality chips, precisely lock in the golden wavelength range of 620-630nm. Through strict automated spectral and color management, ensure that each batch of shipped red LEDs have highly consistent color purity.

2. Dual-effect packaging of matte/transparent, precisely matching light effect requirements
Frosted (Diffused) model: Light is diffused by the frosted gel, with a wide light emission angle (up to 60°-100°), soft and without glare, very suitable for equipment status indicator lights for close observation.
Transparent (Clear) model: Strong focusing power, extremely high brightness penetration, suitable for warning signals requiring long-distance recognition or outdoor strong light environments.

3. 2V standard forward voltage drop, 20mA stable drive
Strictly follow the standard electrical characteristics of red light of 1.8-2.4V. At the rated current of 20mA, maintain the best light emission efficiency and low power consumption performance. Excellent electrical compatibility enables seamless adaptation to various logic circuits and conventional PCB board designs.

4. Excellent anti-oxidation pins, easily passing through wave soldering
The pins use high-quality metal substrate and uniform coating process, with strong anti-oxidation ability, rapid and full soldering. Perfectly compatible with automated wave soldering and manual welding, improving the line throughput rate.

5. Industrial-grade temperature resistance and ultra-long lifespan
Using high-quality epoxy resin packaging, featuring excellent heat resistance, moisture resistance and impact resistance. Can still work stably in the wide temperature range of -40°C to 85°C. Typical service life exceeds 50,000 hours, significantly reducing the maintenance and replacement costs of end devices.

FAQ

Q1: What is the specific dominant wavelength of this red LED, and how do you ensure color consistency across large batch orders?
A: The dominant wavelength is strictly controlled within the 620-630nm spectrum, which is the industry standard for a pure, vibrant red. To guarantee consistency for B2B orders, we utilize an automated binning process that sorts LEDs by both wavelength and luminous intensity. This ensures that every unit in your batch matches perfectly, eliminating visible color variations in your final product.

Q2: From an optical engineering perspective, when should I choose the Diffused package over the Clear package?
A: The choice depends entirely on your viewing requirements. The Diffused package scatters light evenly over a wider angle, making it perfect for status indicators where a soft, glare-free glow is needed for close-up viewing. The Clear package acts as a lens, concentrating the light into a narrow beam for higher intensity and longer viewing distances, which is ideal for outdoor signals or high-ambient-light environments.

Q3: What are the precise thermal constraints during soldering to prevent damage to the internal semiconductor junction?
A: While our epoxy packages are robust, excessive heat can degrade the LED chip. For hand soldering, we strictly recommend a maximum temperature of 260°C for no longer than 3 seconds. If you are using wave soldering, ensure the preheat and solder wave profiles are optimized to keep the component's internal temperature within safe limits, preventing early light decay.

Q4: Can this standard 3mm LED be used directly in outdoor applications exposed to moisture and UV radiation?
A: While the epoxy resin package offers a basic level of moisture resistance, standard DIP LEDs are primarily designed for indoor or protected environments. For harsh outdoor conditions involving direct rain or prolonged UV exposure, we strongly advise either using an IP67-rated sealed variant or ensuring your final assembly provides a conformal coating or waterproof housing to prevent oxidation of the leads and package degradation.
