4-Pin Luxeon-Style High-Power LED Beads Product Introduction
This 4-pin Luxeon-style high-power LED bead is a high-performance light source designed for high-brightness and multi-scenario applications. Its core features are as follows:
✨ Core Product Features
1. Integrated Design with Rich Color Performance
The LED bead adopts a multi-chip integrated solution (commonly RGB three-in-one or dual-color chips), encapsulating red, green, and blue (or two different wavelength) chips under the same lens. It supports independent drive control, enabling various light effects such as monochrome, mixed color, and full-color gradients, meeting diverse needs for atmosphere creation, stage lighting, and color rendering. The lens is made of high-transmittance PC material, offering excellent light-gathering effect, uniform and soft light output, and reduced glare issues.
2. Powerful Brightness with Stable High-Power Performance
The mainstream power range covers 1W~3W (1W per single chip, with higher power achievable via multi-chip combinations). Equipped with high-brightness LED chips, it delivers high luminous flux and excellent luminous efficiency. Compared with traditional low-power LED beads, it significantly boosts brightness, easily meeting the high-brightness requirements of outdoor lighting, stage lights, automotive lighting, phototherapy equipment, and more.
3. 4-Pin Luxeon-Style Packaging with Outstanding Heat Dissipation
Featuring a classic Luxeon-style packaging structure and 4-pin metal lead design, it has a larger contact area with the PCB than standard 2-pin LED beads, greatly improving heat conduction efficiency. It quickly dissipates heat generated by the chips during operation, effectively reducing junction temperature, minimizing light decay, and ensuring long-term stable operation. The combination of a metal substrate and thermal adhesive further enhances heat dissipation, extending the service life of the LED bead.
4. High Durability for Versatile Applications
High reliability: Encapsulated with epoxy resin/silicone, it offers excellent moisture and vibration resistance, adapting well to complex environments such as outdoor and automotive settings.
Long lifespan: With optimized heat dissipation and high-quality chips, it can last over 50,000 hours under normal operating conditions, reducing replacement and maintenance costs.
Wide compatibility: The standard Luxeon-style packaging allows direct replacement of traditional high-power LED beads, offering flexible application with compatibility for various lamp and device circuit designs.
5. Low Energy Consumption and Eco-Friendly
Compared with traditional light sources, this LED bead features high electro-optical conversion efficiency and lower energy consumption. It contains no harmful substances such as mercury, complying with environmental standards. Additionally, it supports low-voltage DC drive for enhanced safety and peace of mind.

5.Precaution
5-1. Handling with care for this product
Because of the LED lens is composed of resin materials. Please avoid the resin area from being pressed,
stressed, rubbed, come into contact with sharp metal nail because the function, performance and
reliability of this product are negatively impacted.Please be aware that this product should not
come into contact withany other parts while incorporating in your lighting apparatus or your other
products.
5-2. Countermeasure against static electricity
Handling of this product needs countermeasures against static electricity because this is a
semiconductor product.-Please take adequate measures to prevent any static electricity being
produced such as the wearing of a wristband or anti-static gloves when handling this product.
Every manufacturing facility in regard to the product (plant,equipment, machine, carrier machine
and conveyance unit) should be connected to ground and please avoid the product to be electric-
charged.ESD sensitivity of this product is over 1000V (HBM, based on JEITA ED4701/304).After
assembling the LEDs into your final product(s), it is recommended to check whether the assembled
LEDs are damaged by static electricity (electrical leak phenomenon) or not.It is easy to find static
damaged LED dies by a light-on test with the minimum current value.
5-3. Caution of product assembly
Roughness, unevenness and burr of surface negatively impact thermal bonding between the product
and heat sink and increase heat thermal resistance between them.Confidence of thermally and
mechanical couplingbetween the product and heat sink are confirmed by checking the mounting
surface and measuring the casetemperature of the product.In order to reduce the thermal resistance
at assembly, it might be good to use TIM (Thermal Interface Material) on whole contact surface of the
product.-In case of using thermal grease for the TIM, it might be good to applyuniformly on the
contact surface of the product.It might be good to make sure that the product heat sink is NOT strained
by stress after solid for assembly to PCB.
5-4. Thermal Design-
The thermal design to draw heat away from the LED junction is most critical parameter for an LED
illumination system. High operating temperatures at the LED junction adversely affect the performance
of LED’s light output and lifetime.
Therefore the LED junction temperature should not exceed the absolute maximum rating in LED
illumination system.
The LED junction temperature while operation of LED illumination system depends upon thermal
resistance of internal LED package (Rj-c), outer thermal resistances of LED package, power loss and
ambient temperature. Please take both of the thermal design specifications and ambient temperature
conditions into consideration for the setting of driving conditions.
5-5. Driving Current
A constant current is recommended as an applying driving current to this product.-In the case of
constant voltage driving, please connect current-imiting resistor to each products in series and control
the driving current to keep under the absolute maximum rating forward current value.Electrical
transient might apply excess voltage, excess current and reverse voltage to the product(s).They also
affect negative impact on the product(s) therefore please make sure that no excess voltage, no excess
current and no reverse voltage is applied to the product(s) when theLED driver is turn-on and/or turn-off.
5-6. Recommended soldering Condition
Soldering shall be implemented using a soldering bit at a temperature lower than 350℃, and shall be
finished within 3 seconds for one land.No external force shall be applied to resin part while soldering
is implemented.Next process of soldering should be carried out after the product has return to ambient
temperature. Contacts number of soldering bit should be within twice for each terminal
