   COB LED is a light source module that directly encapsulates multiple LED chips on a substrate. This design enables COB LED to have a high luminous flux and uniform light distribution. COB LED is usually used in places where high brightness and large area lighting are required, such as commercial lighting, outdoor billboards, etc.
2. SMD (Surface Mount Device) LED:
   SMD LED is a LED chip fixed on a circuit board through surface mounting technology. It is small in size and flexible, and can be easily integrated into various lamps. SMD LED is widely used in home lighting, car lights, display screens and other fields. Its advantages are long life, low energy consumption, and different colors and brightness can be customized according to needs.
3. DOB (Driver On Board) LED:
   DOB LED is an LED light source with integrated driver circuit. Traditional LED lamps require an external driver to control the current, while DOB LED directly installs the driver circuit on the LED circuit board, reducing additional components and connecting wires, and improving the stability and reliability of the system. In addition, due to the reduction of external components, DOB LED is easier to install and more convenient to maintain. Regarding the price, although the cost of DOB LED is slightly higher than that of traditional LED, in the long run, its high efficiency and low maintenance cost make it more cost-effective. If you are interested in the specific price, you can refer to “led dob price”.
4. RGB LED:
   RGB LED can produce a variety of color effects through different combinations of the three basic colors of red, green and blue. It can not only be used as general lighting, but also realize dynamic color changes, which is suitable for scenes such as decorative lighting, stage lighting, and building exterior wall lighting. The flexibility and diversity of RGB LED make it the first choice for designers and users.
5. UV/IR LED:
   UV (ultraviolet) and IR (infrared) LEDs emit ultraviolet and infrared rays respectively, and are mainly used in specific application fields. For example, UV LEDs can be used for medical disinfection and anti-counterfeiting detection; IR LEDs are often used in remote control equipment, security monitoring, etc. The working principle of this type of LED light source is similar to that of visible light LEDs, but there are significant differences in wavelength.
6. AC LED:
   AC LEDs can be directly connected to an AC power source without the need for an additional DC converter or driver. This makes AC LEDs more convenient to install and use, and is particularly suitable for places without complex power systems, such as remote areas or temporary locations. However, AC LEDs have high technical requirements and relatively high manufacturing costs.

Each of the above types of LED light sources has its own advantages, and users can choose the most suitable product according to their actual needs. Whether pursuing efficient energy utilization or seeking innovative design solutions, LED light sources can provide a wealth of choices.
