Which one is better, LED light strip or COB light strip, and what are the differences between them?

With the continuous advancement of science and technology, LED lights and COB lights have become indispensable lighting equipment in people's lives. However, many people do not understand the differences, advantages and disadvantages of these two types of lighting equipment. This article will start from the basic concepts of COB lights and LED lights, discuss the differences, advantages and disadvantages of COB lights and LED lights, and compare them based on actual application scenarios. Finally, we will give selection suggestions suitable for different scenarios.

What are LED lights and COB lights
LED lamp, the full name is light-emitting diode lamp, is a semiconductor light source. It is composed of a PN junction. When electrons and holes recombine in the PN junction, light emission occurs. LED lamps have the advantages of high efficiency, long life, saturated light color, energy saving and environmental protection, so they are widely used in lighting, display, signal and other fields.

COB lamp, which stands for chip packaged lamp bead, is a new type of lighting source. It packages multiple LED chips on the same substrate to form a semiconductor light source to replace traditional LED lamp beads, thereby achieving better light efficiency and higher brightness. COB lamps have the advantages of high light efficiency, uniform light color, and high brightness, so they are widely used in commercial lighting, indoor lighting and other fields.

The difference between COB lights and LED lights
COB lamps and LED lamps are both semiconductor light sources, but they are different in the production of light sources. The LED lamp is composed of a PN junction. When electrons and holes recombine in the PN junction, light emission occurs. COB lamps package multiple LED chips on the same substrate to form a semiconductor light source. Therefore, from the perspective of light source production, COB lights are more advanced than LED lights.

In addition, COB lights and LED lights are also different in terms of light efficiency, uniformity and brightness. Because COB lamps package multiple LED chips on the same substrate, they have higher light efficiency and more uniform light color. The LED lamp bead is composed of a PN junction, so the brightness and light efficiency are relatively low.

Advantages and Disadvantages of COB Lamps and LED Lamps
Advantages and Disadvantages of COB Lamps
Advantages of COB lights:

1. High light efficiency. The luminous efficiency of COB lights is about 30% higher than that of LED lights, so under the same power, COB lights are brighter.

2. The light color is uniform. Because COB lamps package multiple LED chips on the same substrate, the light color is more uniform.

3. Energy saving and environmental protection. COB lamps have high luminous efficiency and can achieve high energy-saving effects; at the same time, because no harmful substances such as mercury are used in the production process of COB lamps, they are more environmentally friendly during use.

Disadvantages of COB lights:

1. The price is higher. Because the production process of COB lamps is more complicated, the price is relatively high.

2. High in calories. Since COB lamps generate a large amount of heat during operation, heat dissipation treatment is required.

Advantages and disadvantages of LED lights
Advantages of LED lights:

1. Long life. The life of LED lights can reach more than 50,000 hours, which is longer than traditional light bulbs.

2. High light efficiency. Although the luminous efficiency of LED lights is lower than that of COB lights, compared with traditional light bulbs and fluorescent lamps, the luminous efficiency of LED lights is still higher.

3. Light color saturation. The light color of LED lights is more saturated than traditional light bulbs and fluorescent lights, and can present more realistic colors.

Disadvantages of LED lights:

1. Low light efficiency. Compared with COB lights, LED lights have lower luminous efficiency.

2. The light color is uneven. Since LED lamp beads have only one PN junction, the light color is not as uniform as that of COB lamps.

Which one is better, COB light strip or LED light strip?
COB light strips and LED light strips are relatively common lighting equipment, and they are different in the way the light source is made. COB light strips package multiple LED chips on the same substrate to form a semiconductor light source, so the light efficiency is higher and the light color is more uniform. The LED light strip is composed of multiple LED lamp beads. Although the light efficiency is lower than that of the COB lamp, it has a longer lifespan.

Depending on the application scenario, the choice between COB light strips or LED light strips should be different. If it is a commercial lighting scene that requires high color requirements, it is recommended to choose COB light strips. If it is an indoor lighting scene that requires long-term work, it is recommended to choose LED light strips.

Application scenarios of COB lights and LED lights
COB lights and LED lights have different advantages in different application scenarios. The following analyzes are conducted from two aspects: commercial lighting and indoor lighting:

commercial lighting
Commercial lighting scenes require higher color requirements, so it is recommended to choose COB lamps. Because COB lamps package multiple LED chips on the same substrate, the light color is more uniform and can present more realistic colors. At the same time, the light efficiency of COB lamps is also higher and can achieve better lighting effects.

Indoor lighting
Indoor lighting scenes require long working hours, so it is recommended to choose LED lights. Although the luminous efficiency of LED lights is lower than that of COB lights, compared with traditional light bulbs and fluorescent lamps, the luminous efficiency of LED lights is still higher. At the same time, the life of LED lights is also longer, which can meet the needs of indoor lighting for a long time.

Suggestions for choosing COB lights and LED lights
Depending on the application scenario, the choice between COB lights or LED lights should be different. The following are suggestions for selection in different scenarios:

1. Commercial lighting scene: It is recommended to choose COB lamps, which can meet the demand for higher color requirements.

2. Indoor lighting scenarios: It is recommended to choose LED lights, which can meet the needs of long-term lighting.

3. Other scenarios: Choose COB lights or LED lights according to actual needs
