The Difference and Advantages and Disadvantages of Lamp Beads and Patches

Lamps are inseparable from our lives. In our lives, the appearance of various lightings brings many conveniences to people's lives. Among the various lighting products, the two types of lighting, led lamp beads and patches, have attracted consumers' attention. For these two different lighting types, what are the main differences between them?

The difference between led lamp beads and patch 　 　

Let’s first take a look at what are the characteristics of the LED lamp beads? The angle of the LED lamp beads is very small. The light is relatively concentrated, and the range is very far, but the irradiation range is limited; while the general angle of the LED patch is very large. Belongs to the light is relatively scattered, the irradiation range is wide, but the range is relatively short. LED lamp beads are used for discharge light emission, while LED patches are used for cold light emission.

In contrast, what are the advantages of SMD? SMD LED is also a kind of LED lamp beads. Common LEDs have two or four pins, and some do not have pin-shaped pins, and they are soldered close to the copper foil of the circuit board. The key to choosing lamp beads is to consider the color temperature, color rendering index, luminous efficiency, luminous decay, and the quality of the power supply.

What is the difference between them? There are many forms of LED lamp beads, which are mainly formulated in consideration of various power dissipation forms.

The advantages and disadvantages of each　　

For led lamp beads, what is its advantage? The shape of cob led lamp beads in LED lamps has undergone direct insertion and patching. With technological progress, it is logical that multiple LED light-emitting chips are highly integrated and directly packaged in On the substrate (integrated design of circuit and heat dissipation), a compact, high-power, ultra-high-power LED light-emitting element is formed, which is "COB".　　

As for the patch, what are its advantages? Integrated LED is generally another name for COB light sources in the market, but in fact, the characteristics of COB light sources cannot be clearly described. COB refers to Chip-On-Board, which directly encapsulates low-power chips on an aluminum substrate to quickly dissipate heat. The chip area is small, the heat dissipation efficiency is high, and the drive current is small. Therefore, it has low thermal resistance, high thermal conductivity, and high heat dissipation. Compared with ordinary SMD low-power light source features higher brightness, low thermal resistance.

If the light is on, it means that the lamp bead is basically functional. If it does not light up, exchange the red and black test leads, and test again. In order to avoid the cathode and anode of some lamp beads are opposite to the general ones. The lamp bead lights up to observe the color of the lamp bead and whether the color temperature meets the requirements. Whether the brightness is appropriate. Choose suitable lamp beads. Therefore, we found that both of them have their own advantages.　　

In summary, LED lamp beads and patches each have their own advantages. When you are interested in buying lighting, you can buy different styles and different types of products according to your own choice. Speaking of LED lamp beads and patches, their scope of use is not the same. At this time, everyone can choose according to their needs.
