The LEDs described here are intended to be used for ordinary electronic equipment (such as office equipment, 

communication equipment and household applications). Consult Betlux’s Sales in advance for information on 

applications in which exceptional reliability is required, particularly when the failure or malfunction of the LEDs

 may directly jeopardize life or health (such as in aviation, transportation, traffic control equipment, medical 

and life support systems and safety devices).

CAUTIONS for Through-Hole LED Lamps

1. Application
The LEDs described here are intended to be used for ordinary electronic equipment (such as office equipment, communication equipment and household applications). Consult Betlux’s Sales in advance for information on applications in which exceptional reliability is required, particularly when the failure or malfunction of the LEDs may directly jeopardize life or health (such as in aviation, transportation, traffic control equipment, medical and life support systems and safety devices).

2. Storage
The storage ambient for the LEDs should not exceed 30℃ temperature or 70% relative humidity. It is
recommended that LEDs out of their original packaging are used within three months
For extended storage out of their original packaging, it is recommended that the LEDs be stored in a sealed
container with appropriate desiccant or in a desiccator with nitrogen ambient.

3. Cleaning
Use alcohol-based cleaning solvents such as isopropyl alcohol to clean the LED if necessary

4. Lead Forming & Assembly
During lead forming, the leads should be bent at a point at least 3mm from the base of LED lens. Do not use
the base of the leadframe as a fulcrum during forming.
Lead forming must be done before soldering, at normal temperature.
During assembly on PCB, use minimum clinch force possible to avoid excessive mechanical stress.

Soldering

When soldering, leave a minimum of 2mm clearance from the base of the base of the lens to the soldering point. Dipping the lens into the solder must be avoided.

Do not apply any external stress to the lead frame during soldering while the LED is at high temperature.

Recommended soldering conditions:

Note: Excessive soldering temperature and/or time might result in deformation of the LED lens or failure of the LED

ESD(Electrostatic Discharge)

Static Electricity or power surge will damage the LED.

Suggestions to prevent ESD (Electrostatic Discharge):

n Use a conductive wrist band or anti-electrostatic glove when handling these LEDs

n All devices, equipment, and machinery must be properly grounded

n Work tables, storage racks, etc. should be properly grounded

n Use ion blower to neutralize the static charge which might have built up on surface of the LED’s

 plastic lens as a result of friction between LEDs during storage and handling

ESD-damaged LEDs will exhibit abnormal characteristics such as high reverse leakage current, 

low forward voltage, or “no light on” at low currents. To verify for ESD damage, check for “light on” 

and Vf of the suspect LEDs at low currents.

The Vf of “good” LEDs should be>2.0V@0.1mA for InGaN product and >1.4V@0.1mA for AlInGaP

Drive Method

An LED is a current-operated device. In order to ensure intensity uniformity on multiple LEDs connected in 

parallel in an application, it is recommended that a current limiting resistor be incorporated in the drive circuit,

 in series with each LED as shown in Circuit A below.

When selecting power for LED systems, it’s essential to understand several key parameters to ensure safe operation, longevity, and optimal performance. Here are some steps and considerations for LED power selection:

  • Determine the Forward Voltage (Vf) of the LED(s):

Each LED has a forward voltage, which is the voltage at which the LED operates when the current is flowing through it. This value can typically be found in the LED’s datasheet.

  • Determine the Forward Current (If) of the LED(s):

The forward current is the current at which the LED is designed to operate. Running an LED at higher than its rated current can reduce its lifespan and increase the heat it produces.

  • Decide on the Configuration:

Series Configuration: When LEDs are connected in series, the forward voltages add up, but the current remains the same.

Parallel Configuration: When LEDs are connected in parallel, the forward voltage remains the same, but the currents add up. This configuration can be risky because if one LED fails or has a slightly lower forward voltage, it can cause the other LEDs to draw more current.

Calculate Total Power Requirements:

Power (W) = Total Forward Voltage (V) x Total Forward Current (A)

For example, if you have three LEDs connected in series, each with a forward voltage of 3V and a forward current of 20mA, the total power requirement would be:

Power = (3V + 3V + 3V) x 20mA = 9V x 0.02A = 0.18W

  • Select an Appropriate Power Supply:
  • Voltage Rating: The power supply voltage should match or slightly exceed the total forward voltage of your LED configuration.
  • Current Rating: The power supply’s current rating should meet or exceed the total forward current of your LED configuration.
  • Safety Margin: It’s a good practice to select a power supply that can provide at least 20% more power than your calculated requirement. This ensures the power supply isn’t operating at its maximum capacity, which can extend its life and ensure safer operation.
  • Consider Additional Features:
  • Dimming Capability: If you want to control the brightness of your LEDs, choose a power supply with dimming capabilities.
  • Overcurrent and Overvoltage Protection: To protect your LEDs, select a power supply with built-in protection mechanisms.
  • Thermal Management: Ensure that the power supply has adequate cooling, especially if it will be enclosed or in a location with limited airflow.
  • Regulation and Efficiency:A power supply with good regulation will maintain a consistent voltage output despite variations in the load. High efficiency ensures minimal power is wasted as heat.
  • Physical Size and Form Factor:Depending on where you plan to place the power supply, its size and shape may be critical factors.

In summary, when selecting power for LED systems, understanding your LED’s requirements and the configuration you plan to use is essential. Then, pick a power supply that meets those needs with some added safety margin, keeping in mind any additional features or constraints relevant to your project.
