LED display are popular among users due to their advantages of high brightness, high contrast, long life and low energy consumption.
In the composition of LED display, lamp beads, as one of the core components, directly affect the display effect and service life of the entire screen. Therefore, how to choose suitable LED lamp beads has become a topic worth discussing.
This article will reveal the secrets of how to choose high quality lamp beads.
What Different Types of Lamp Beads Are Available?
Lamp beads come in various types, each suited for specific applications. Understanding these types helps in selecting the right one for your display needs.
1. SMD (Surface-Mount Device) LED
This type of lamp bead is like a small sticker that can be directly pasted on the circuit board. They come in many models, such as 2835, 3528, 5050, etc. These numbers actually indicate the size of the lamp bead. For example, 2835 means the width is 2.8 mm and the length is 3.5 mm. Due to its small size and high brightness, this type of lamp bead is widely used in various electronic devices. If used for home lighting, the 2835 and 3014 models are very suitable because they are energy-saving and suitable for home use.
There is also a high-power LED lamp bead:
This lamp bead is like a small “powerful bulb” because it is very bright and powerful. It is usually used in places that require high brightness, such as outdoor billboards and stadium lighting. If you need bright lighting at home, you can also consider using this lamp bead.
By understanding these different types of lamp beads, you can have more confidence in choosing the product that best suits your lighting needs.
2. DIP (Dual In-line Package) LED
DIP LED are known for their robust construction and high brightness. They are often used in outdoor displays where durability and visibility in sunlight are crucial.
3. COB (Chip on Board) LED
COB is actually the abbreviation of “Chip On Board“, which means that many LED chips are packaged together to form a powerful light source. The advantage of this design is that it provides a more uniform and efficient lighting effect. Therefore, if you need uniform and bright lighting, COB LED lamp beads are an excellent choice.
When choosing LED lamp beads, in addition to considering the type, you should also pay attention to key parameters such as brightness, color temperature, life, energy efficiency, as well as the brand’s reputation and after-sales service. At the same time, it is crucial to choose the right type and specification of lamp beads according to specific application scenarios and needs.
Please note that with the continuous advancement of technology, the types and performance of LED lamp beads are also continuously updated and optimized. In order to ensure that you buy the most suitable products, it is recommended to consult professionals or check the latest information to obtain the latest product information and recommendations.
4. Micro LED
Micro LED technology is emerging as a game-changer, offering incredible brightness and energy efficiency. Although currently more expensive, it promises future advancements in display technology.
What Are the Specifications and Technical Details of the Lamp Beads Provided by the Supplier?
Understanding the technical specifications of LED lamp beads is vital to ensure compatibility and performance. Key factors to consider include:
1. Brightness
Measured in lumens, brightness determines how vivid the display appears. Choose lamp beads with appropriate lumens to suit the display environment.
2. Color Temperature
Color temperature affects the visual appeal and readability of the display. Options typically range from warm (2700K) to cool (6500K) tones.
3. Viewing Angle
The viewing angle influences how well the display is seen from different positions. Wider angles are preferable for larger audiences.
4. Lifespan
A longer lifespan ensures durability and reduces maintenance costs. Look for lamp beads with at least 50,000 hours of operational life.
5. Packaging Material
Packaging material is like the “outer coat” of the lamp bead, protecting the internal structure of the lamp bead. Different packaging materials will affect the durability and reliability of the lamp bead.
How to Judge the Quality of LED Display Beads
Judging the life of LED lamp beads involves multiple aspects, including luminous efficiency attenuation, thermal management, current voltage stability, lamp design quality and use environment. The following key factors are explained in detail:
Overlooking efficiency attenuation:
The life of LED lamp beads is usually represented by L70 life, that is, after a certain period of time, the luminous efficiency drops to about 70%of the initial value. This is an important indicator for evaluating LED lamp life. By measuring the luminous efficiency of LED lamp beads at different time points, their life span can be calculated.
Hot management:
LED lamp beads are very sensitive to calories, and too high temperatures will significantly reduce their life. Therefore, good thermal management is crucial, including reasonable heat dissipation design, high -quality heat dissipation materials and efficient heat dissipation structures, which can help extend the life of LED lamp beads.
Current and voltage:
The right current and voltage are also crucial to the life of LED lamp beads. Excessive current and voltage may damage the LED chip or accelerate its attenuation. Therefore, when selecting power and drive, make sure they can provide stable current and voltage for LED lamp beads.
Use environment:
The use environment will also affect the life of LED lamp beads. The use of LED lamp beads in high temperature and high humidity environment will accelerate its aging and damage. Therefore, when selecting the environment, it is necessary to consider its potential impact on LED lamp bead life.
In addition to the above factors, you can also evaluate the life of LED lamp beads through some experiments and test methods. For example, aging tests can simulate the performance changes of LED lamp beads under long -term use, thereby predicting its life.
In addition, the use of professional testing equipment to measure parameters such as the optical flux, and the color of color rendering index of LED lamp beads can more comprehensively evaluate its performance and quality.
What Is the Industry Standard for the Quality of LED Display Beads?
Industry standards ensure that LED lamp beads meet specific performance and safety criteria. Key standards include:
1. ISO Certification
ISO certification reflects adherence to international quality management systems, assuring reliability.
2. RoHS Compliance
RoHS compliance indicates that the lamp beads are free from hazardous materials, promoting environmental sustainability.
3. CE Marking
The CE marking signifies conformity with EU safety, health, and environmental protection directives.
4. LM-80 Testing
LM-80 testing provides data on LED longevity and light degradation, helping predict lifespan and performance.
Conclusion
In fact, only by considering these factors comprehensively can we ensure that we can choose the right LED display lamp beads to ensure the stable operation and long-term benefits of the display.
