Answer: 2mm, 3mm, 4mm, 5mm, 8mm and 10mm, etc.
Answer analysis: There are many sizes of LED direct plug lamp beads, and common sizes include 2mm, 3mm, 4mm, 5mm, 8mm and 10mm, etc. These sizes mainly indicate the diameter of the LED lamp beads, and different sizes correspond to different light output, brightness and application scenarios.
1. 2mm LED direct plug lamp beads: LED lamp beads of this size are usually used in very compact spaces, such as some small electronic devices or indicator lights. Due to its small size, the light output and brightness are relatively low, but it is enough to meet the lighting needs of some specific occasions.
2. 3mm LED direct plug lamp beads: LED lamp beads of this size are widely used in various small lighting and display devices, such as watches, calculators, small lamps, etc. Its light output and brightness are moderate, which can meet the general small lighting needs.
3. 5mm LED direct plug-in lamp beads: This is one of the most common sizes of LED direct plug-in lamp beads, which are widely used in various lighting and display fields, including home lighting, commercial lighting, outdoor billboards, automotive lighting, etc. 5mm LED lamp beads have higher light output and brightness, which can meet a variety of lighting needs.
4. 8mm and 10mm LED direct plug-in lamp beads: These two sizes of LED lamp beads are larger-sized LED lamp beads, which are usually used in occasions that require higher brightness and wider lighting range, such as outdoor billboards, stage lighting, urban night scene lighting, etc. Due to their larger size, they can provide stronger light output and higher brightness, ensuring good lighting effects in various harsh environments.
It should be noted that in addition to size, when choosing LED direct plug-in lamp beads, it is also necessary to consider parameters such as their luminous angle, color and light intensity. These parameters will directly affect the lighting effect and application range of LED lamp beads. Therefore, when choosing LED direct plug-in lamp beads, it is necessary to make comprehensive considerations based on specific application scenarios and needs.
In addition, with the continuous advancement of technology and the emergence of new materials, more sizes and specifications of LED direct plug lamp beads may appear in the future. Therefore, when choosing LED direct plug lamp beads, you also need to pay attention to the latest trends and technological developments in the industry.
