1. Application
The Seven Segment LED is widely applied for ordinary electronic equipment (such as office equipment,
communication equipment and household applications). Checking with 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

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

3. Cleaning
Avoid using any unspecified chemical solvent to clean LED . For example, Trichloroethylene, Chlorosen, Acetone, and Diflon S3MC.
Any cleaning method can only be taken under normal temperature in one minute or less if it is required.
Use water to clean the Seven Segment LED if necessary under room temperature
dry it immediately after that.

Any unsuitable stress applied to the epoxy may break bonding wires in LED
Any forming on lead pin must be done before soldering, not during or after soldering.
Avoid applying any stress to resin in order to prevent the epoxy fracture and break on bonding wire.
While forming, please use a tie bar cut or equivalent to hold or bend the pin.
2mm from the base of resin is the minimum distance for the place bending the lead pin.
Avoid bending the lead pin at the same point twice or more.

seven segment display forming caution


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.

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

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.
