LED lamp bead

LED lamp bead classification

‌ 1.Sort by luminous color ‌ : ‌

• Red LED lamp beads: ‌ emit red light, ‌ wavelength between 620-750 nm. ‌
• Blue LED lamp beads: ‌ emit blue light, ‌ wavelength of about 450 nm. ‌
• Green LED lamp beads: ‌ emits green light, ‌ wavelength of about 500-550 nm. ‌
• Yellow LED lamp beads: ‌ emits yellow light, ‌ wavelength of about 580-600 nm. ‌
• Purple LED lamp beads: ‌ emit purple light, ‌ wavelength of about 420-450 nm. ‌

‌ 2.Classified by package ‌ : ‌

• In-line LED lamp beads: ‌ such as 3mm, ‌5mm and other models, ‌ is often used for display screen, ‌ decorative lights and so on. ‌
• Chip LED lamp beads: ‌ such as 2835, ‌3528 and other models, ‌ is widely used in lamp belt, ‌ panel light and so on. ‌
• High power LED lamp beads: ‌ such as 1W, ‌3W and other models, ‌ for high brightness lighting occasions. ‌
• COB LED lamp beads: ‌ will be a number of LED chips packaged together, ‌ to provide better lighting effect. ‌
• SMD LED lamp bead: ‌ the LED chip is welded to one end of the substrate, ‌ small size, ‌ high brightness ‌.

led headlight beads and small light beads difference

‌ 1.Power and brightness ‌ : ‌

• High-power LED lamp beads: ‌ power is usually between 1W and hundreds of watts, ‌ high brightness, ‌ suitable for large lighting equipment, ‌ such as street lamps, ‌ stage lights and so on. ‌
• Low power LED lamp beads: ‌ power is generally between 0.06W and 0.5W, ‌ brightness is low, ‌ is suitable for indicator lights and small lighting equipment. ‌

2‌. Application scenario ‌ : ‌

• High-power LED lamp beads: ‌ because of its high brightness and high efficiency, ‌ is more suitable for occasions that need strong lighting. ‌
• Low-power LED beads: ‌ are often used in situations where low power consumption and small lighting range are required. ‌

‌ 3.Heat dissipation requirements ‌ : ‌

• High-power LED lamp beads: ‌ because of the higher power, ‌ generated more heat, ‌, so the need for better heat dissipation design. ‌
• Small power LED lamp beads: ‌ heat dissipation requirements are relatively low.

4. Frequently Asked Questions and Answers

• - Select power and light color according to application requirements.
• - Consider whether the operating voltage and current range meets the power supply requirements.
• - Pay attention to the heat dissipation performance and use environment of the lamp beads.

• - The lamp bead is not bright: it may be a poor power connection or the lamp bead is damaged.
• - Insufficient brightness: may be insufficient power supply current or lamp bead aging.
• - Color offset: The chip temperature may rise due to poor heat dissipation.

• - Use constant current power supply to drive LED lamp bead, keep current stable.
• - Strengthen heat dissipation design, reduce chip temperature.
• - Avoid frequent switching and overvoltage shocks.
