Which is better, LED strip light or COB strip light?

With the continuous advancement of technology, LED strip lights and COB strip lights have become indispensable lighting equipment in people's lives. However, many people do not understand the differences and advantages and disadvantages of these two lighting equipment. This article will start with the basic concepts of COB strip lights and LED strip lights, explore the differences, advantages and disadvantages of COB strip lights and LED strip lights, and compare them in combination with actual application scenarios, and finally give selection suggestions suitable for different scenarios.

What are LED strip lights and COB strip lights

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

COB strip lights, the full name of which is chip packaged strip lights, are 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 strip lights 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.

Differences between COB strip lights and LED strip lights
Both COB strip lights and LED strip lights are semiconductor light sources, but they are different in the production of light sources. LED strip lights are composed of a PN junction. When electrons and holes recombine in the PN junction, light emission will occur. COB strip lights encapsulate multiple LED chips on the same substrate to form a semiconductor light source. Therefore, from the perspective of light source production, COB strip lights are more advanced than LED strip lights.

In addition, COB strip lights and LED strip lights are also different in terms of light efficiency, uniformity and brightness. Since COB strip lights encapsulate multiple LED chips on the same substrate, the light efficiency is higher and the light color is more uniform. LED strip light beads are composed of a PN junction, so the brightness and light efficiency are relatively low.

Advantages and disadvantages of COB strip lights and LED strip lights

Advantages of COB strip lights:

1. High luminous efficiency. The luminous efficiency of COB strip lights is about 30% higher than that of LED strip lights. Therefore, at the same power, COB strip lights have higher brightness.

2. Uniform light color. Since COB strip lights encapsulate multiple LED chips on the same substrate, the light color is more uniform.

3. Energy saving and environmental protection. COB strip lights have high luminous efficiency and can achieve high energy saving effects; at the same time, since COB strip lights do not require the use of harmful substances such as mercury during the production process, they are more environmentally friendly during use.

Disadvantages of COB strip lights:

1. High price. Since the production process of COB strip lights is more complicated, the price is relatively high.

2. High heat. Since COB strip lights generate a lot of heat during operation, heat dissipation treatment is required

Advantages of LED strip lights:

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

2. High light efficiency. Although the light efficiency of LED strip lights is lower than that of COB strip lights, it is still higher than that of traditional strip lights and fluorescent strip lights.

3. Saturated light color. The light color of LED strip lights is more saturated than that of traditional strip lights and fluorescent strip lights, and can present more realistic colors.

Disadvantages of LED strip lights:

1. Low light efficiency. Compared with COB strip lights, the light efficiency of LED strip lights is lower.

2. Uneven light color. Since LED strip light beads have only one PN junction, the light color is not as uniform as COB strip lights.

Which is better, COB strip light or LED strip light?
COB strip light and LED strip light are both common lighting equipment, and they differ in the way the light source is made. COB strip light is to encapsulate 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. LED strip light is composed of multiple LED lamp beads. Although the light efficiency is lower than that of COB lamp, the life span is longer.

Depending on different application scenarios, the choice of COB strip light or LED strip light should be different. If it is a commercial lighting scene that requires high color requirements, it is recommended to choose COB strip light. If it is an indoor lighting scene that needs to work for a long time, it is recommended to choose LED strip light.

Application scenarios of COB lamps and LED lamps
COB lamps and LED lamps have different advantages in different application scenarios. The following analysis is made from two aspects: commercial lighting and indoor lighting:

Commercial lighting
Commercial lighting scenarios require high color requirements, so it is recommended to choose COB lamps. Since COB lamps encapsulate multiple LED chips on the same substrate, the light color is more uniform and can present more realistic colors. At the same time, COB lamps have higher luminous efficiency and can achieve better lighting effects.

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

Suggestions for choosing COB lamps and LED lamps
Depending on different application scenarios, the choice of COB lamps or LED lamps 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 needs of high color requirements.

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

3. Other scenes: Choose COB lamps or LED lamps according to actual needs.
