Product Description

1).High quality warm white chip 2835 smd led 0.2w the vertical structure: Chip direct conduction fins to improve the heat dissipation performance, which can withstand the higher current (40-60mA)

2).Large heat sink: larger than 3528,3014 heat sink 2-3 times, excellent heat dissipation design, light decay of LED chip life more secure

3).Oversized light-emitting surface: to improve the rate of light: up to 90%.

4).Ultra-thin structure: to solve the 3528,3014 been long-standing problem spot;

5).High optical efficiency: higher than 3528,3014 luminous efficiency 2-3 times the luminous efficiency of up to 90-100LM / W;

6).Super stability: low light fades material, process, process maturity and stability.

7). The high cost: to achieve the same luminous flux, than 3528,3014 costs reduced more than 20%

Packaging & Delivery

Packaging Details

4000pcs/reel, each reel Anti-static vacuum Bag


Delivery Time

Shipped in 3-5 days after payment

 

image007.jpg

Cautions:

1)Soldering Conditions

Number of reflow process shall be less than 2 times and cooling process to normal temperature is required between first and Second soldering process.


2)Static Electricity

It is recommended that a wrist band or an anti-electrostatic glove be used when handling the LEDs.All devices, equipment and machinery must be properly grounded.Damaged LEDs will show some unusual characteristics such as the forward voltage becomes lower, or the LEDs do not light at the low current. Criteria : (VF > 2.0V at IF=0.5mA) 


3)Moisture Proof Package

It is recommended that moisture proof package be used .


4)Storage

Before opening the package ,The LEDs should be kept at 30°C or less and 70%RH or less. The LEDs should be used within a year.


5)After opening the package, The LEDs should be soldered within 24 hours (1days) after opening the package.
