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

 product.

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.

Surface Mount Devices (SMDs) refer to electronic components mounted directly onto a printed circuit board (PCB) surface. SMDs are well-suited for automated assembly lines as they are placed on PCB using pick-and-place machines and then soldered, making production faster and more efficient.

Examples of SMDs are passive components like resistors and capacitors, active components like transistors and diodes, and Surface Mount LEDs often called SMD LEDs. This blog will teach us about SMD LEDs, including their packages, types, and SMD LED vs COB (chip-on-board) LED.

What are SMD LEDs

An LED or Light-emitting Diode is a semiconductor device, which emits light when electric current is passed through it. They produce light through a process called electroluminescence - when electrons gain energy from the applied voltage, they release that energy as photons (light) when they return to a lower energy state.

A surface mount Device light-emitting diode (SMD LED) is a type of LED that is designed to be mounted directly onto the PCB using SMT assembly.

SMD LEDs are compact, highly efficient, and versatile in design. They are ideal for a variety of lighting applications from household and commercial use to industrial applications.

They allow a variety of colors in output, have a high brightness, and use energy efficiently. Each package is recognized by numbers that represent its physical dimensions in millimeters (mm).

Common SMD LED Packages and Specifications

Many SMD LED packages are standardized owing to their usefulness in different applications and scenarios. They vary in size (physical dimensions), power consumption, level of brightness, and how efficiently they use energy. A few common packages are discussed here.

SMD LED

The LED SMD package has a very low power consumption and is available in colors of red, green, blue, white, etc. It's compact and light, suitable for tight spaces and portable applications. It is used in backlighting, indicator lights in compact devices, and lighting in wearables.

SMD LED

The LED SMD has a better light output than the package. It finds applications in indicator lights in consumer electronics, backlighting for buttons and displays, and decorative lighting in automotive and home applications.

SMD LED

The LED SMD package makes a good balance between size and light output. It's used for general lighting for applications requiring a moderate brightness level.

SMD LED

The LED SMD package is commonly used in applications that have lower power consumption, such as indicator lights, lighting for ambiance, etc. It is typically used in scenarios where intense brightness is not required. However, energy efficiency is preferred.

SMD LED

SMD LED is larger in size or dimensions. It can have three diodes, which enables it to produce more light and support variations in RGB color. This package is widely used in applications that require higher brightness. Commonly, we can find SMD LEDs in LED strips, floodlights, and solutions providing high-output lighting.

SMD LED

SMD LED is an enhancement of , and is known for providing high brightness and better energy efficiency compared to the latter. This package is suitable for applications that require high output without having a tremendous increase in power consumption. The applications include ceiling lights, panel lights, etc.

SMD

SMD LED 's size is smaller than that of or . It offers an ample amount of brightness with reasonable energy efficiency. It is well-suited for specialized lighting applications such as backlighting and automotive lighting.

SMD

The package is smaller in size but its lighting is highly efficient. Therefore, it is best suited for applications that require compact designs and structures with high-output light. Often, it is used in architectural lighting and compact lighting solutions.

SMD

SMD LED is designed for applications where space is very limited, as in slim LED strips, wearables, etc.

SMD LED vs COB LED

SMD LED and COB (Chip-on-Board) LED are two common types of LED technologies used for lighting applications. They differ in various aspects including design, performance, and functionality.

1. Design

An SMD LED consists of separate light-emitting diodes mounted directly onto a PCB, while a COB LED integrates multiple diodes onto a single chip, which is mounted on a board.

SMD LED allows for individual control of color and brightness, while COB LEDs combine all diodes in a large efficient light emitting area, producing a more concentrated and intense light.

2. Heat management

In SMD LEDs, heat dissipation is moderate but must be managed well using cooling mechanisms, specifically in applications where multiple LEDs are grouped, such as LED strips.

In contrast, COB LEDs have extremely good heat dissipation abilities, as the diodes are spread out on a larger area, so heat is evenly distributed and doesn't require much cooling.

3. Efficiency

SMD LEDs are efficient but their efficiency is dependent on the design or structure of the lighting solution, whereas COB LEDs are more efficient owing to their streamlined design.

4. Brightness

SMD LEDs offer high brightness that can be adjusted according to the arrangement and number of diodes they have. On the other hand, COB LEDs produce very bright and focused light owing to that all the diodes are packed into a small chip.

5. Light output and distribution

The SMD LED gives a focus and directional light, for which we use reflectors or lenses to control its beam angle.

On the contrary, COB LEDs offer an evenly distributed broader output providing an intense source of light.

6. Color options

SMD LED can produce different colors. They are available in RGB (Red, Green, Blue) versions, which allow them to mix and match colors for different applications. In contrast, COB LEDs are more limited in terms of color output. Since they integrate all diodes onto a single chip, they typically emit a single color or a fixed range of colors.

Overall, SMD LED is used for basic devices, and COB LED serves more advanced applications, due to its high brightness, uniform light, and excellent thermal dissipation.

Types of SMD LEDs

Here are the three types of SMD LEDs:

1. Chip SMD LEDs

Chip SMD LEDs, the most commonly used SMD LEDs, are flat and compact, often placed directly on a circuit board, allowing for better heat dissipation and easier mass production. They are made up of a small semiconductor die mounted on a lead frame. The lead frame connects to external terminals, which carry the electrical signal to the LED chip.

2. Top SMD LEDs

3. Sideview SMD LEDs

To assemble the SMD components on the PCB, a process called surface mount technology (SMT) is used.

Sideview SMD LEDs are specifically designed to emit light sideways, parallel to the circuit board. They are often used in edge-lighting applications, such as backlit keyboards or displays. The LED is oriented so that the light is emitted from the side of the component, instead of directly upwards. This makes them useful for applications where low-profile lighting or side illumination is needed.
