Top 8 important issues for clients in the
The team compiled those issues.
Currently on the market LED packaging companies are numerous, staggering a variety of small and medium-sized enterprises, the overall production process is excellent mixed, so the industry competitive pressure, resulting in the emergence of a lot of bad money to drive out the good money, thus allowing customers to lose confidence in the Chinese market as it should be. Let the end consumer understand that China is making rubbish products and fraudulent products it is not so but because our suppliers want to expand the profitability of the situation made against the rules of the game of equal product trading.
GOY appeared to maintain the purpose of the customer so that customers belonging to their own should get the goods and prices in line with the product, we will list the LED beads products of several technical analyses and problems to show our understanding of the industry.
LED light-emitting diode (SMD beads) components:
Components include bracket, chip, glue, phosphor, wire (chip and bracket conductive), and bottom glue.
Our friends and cooperative customers at present ask our GOY technical team the most questions in the entire industry.
1. What brand of the beads?
2. What chip of the bead?
3. What is the brightness of the bead?
4. What is the of the lights?
5. What is the of the whole ?
6. How much is the color rendering?
7. How much W is used for the LED?
8. What kind of bracket is the LED?
Comprehensive above, we have the market analysis of these issues. From the purchasers of view, to avoid some unreasonable problems. Thus ensuring that the price of goods purchased matches the product.
1. LED bead brand
In the early years due to the immaturity of the production process, the process and the overall technical quality of the personnel were not high, so China's production of beads in the market retention was very small, at that time, mainly to Japan, the USA, South Korea as the country of origin. With the introduction of industry equipment and encapsulation technology to share and innovate with each other, thus driving the development of China's local brand building, on behalf of the , National Star, , and other brand building, and many foreign brands are also carried out in China's local production of their products.
So for the time being, as long as the beads meet the design life and design parameters, we don't have to think too much about the brand, because the brand will bring a higher brand premium, which is to be passed on to customers. Of course, in the case of reasonable market demand, we can also use international brands.
2. LED chip
The current LED chip problem is the same power with the same voltage with the brightness of different manufacturers in the production, so that the supplier is profitable, many supplier’s standard is to use the large size of the product for quotation and sample, but in the case of large quantities of goods with a small size of the parameters of roughly the same product supply, resulting in the lamps and lanterns attenuation of the great, up to the use of the life span of the effect of the need to maintain. This problem requires a professional to carry out data comparison and size measurement to avoid this mixed trick.
3. Lamp bead brightness and what brightness and light effects
These three challenges are interconnected with the chip size in the material processing concentration. Understanding the power consumption of LED chips is crucial; for instance, when using 0.2W LED chips, varying chip dimensions yield differing luminous flux (LM) outcomes and efficacies (LM/W). Our technology is instrumental in navigating these complexities.
Currently, our team, in collaboration with suppliers, successfully attains the desired brightness levels (LM) and luminous efficiency (LM/W) while maintaining a careful balance between chip size, cost-effectiveness, and quality. This approach ensures optimal benefits for our customers. Moreover, we are dedicated to developing a diverse range of products and pioneering energy-efficient solutions, all tailored to meet specific needs and push the boundaries of performance.
4. Rendering Ra how much
The ongoing phosphor iteration upgrades have enabled the market, in its pursuit of high-end performance, to simulate sunlight with a near-perfect color rendering index (CRI) of Ra99. Consequently, in the current scenario, SMD LED chips can be manufactured within the broad range of RA60-99 to meet specific customer demands. However, an issue arises where the inclusion of red phosphors to achieve enhanced color rendering leads to a compromise in light efficiency. This necessitates the intervention of skilled technical engineers who must optimize the luminous efficacy (LM/W) while addressing the heightened color rendering requirements. Typically, such adjustments denote a move towards customized product solutions.
5. How many W lamp beads?
This matter is intricate, as it entails determining the total lamp power of the customer before allocating it to individual LED chips, factoring in the controller's power consumption. Given the customer's overall lamp power, our task is to select suitable LED chips with matching power ratings. We then tailor the configuration based on additional photoelectric parameters provided by the customer. A critical consideration in this process is the lamp's heat dissipation capability. In instances of inadequate heat dissipation, we adjust by employing larger LED chips with lower thermal resistance to effectively manage heat generation. This strategy is vital for ensuring the designed lifespan of the lamp and controlling light attenuation. The GOY team leverages its expertise to holistically integrate components, striking a balance between product performance and cost-effectiveness. Our comprehensive approach guarantees optimized solutions tailored to customer needs.
6. LED bracket
The core of the current problem lies in the choice of thermally conductive materials, especially the difference between the iron bracket and the copper bracket, which have a large difference in market price. Generally speaking, iron brackets are mostly used for low-power products, and copper brackets are mostly used for about 0.5 watts, although there may be exceptions in special customized cases. An easy way to distinguish between the two is to use a magnet attracted to the iron mount. In addition, the choice of insulating optical material is also crucial, which concerns the choice of plastic materials, such as PPA, PCT, EMC, ceramics, etc., which are currently the mainstay. By clearly agreeing on the material specifications with the supplier and signing a contract, the risk of material stealing can be effectively avoided, as the supplier is usually unwilling to bear the consequences of large-scale returns due to small cost differences. At the same time, with the help of professional testing organizations to carry out sample testing, potential problems can also be detected on time.
The above summarises a brief analysis by our team of common customer issues. For more in-depth information on specific solutions to these points, please feel free to contact a member of the GOY team for further professional answers and support.
