With the continuous advancement of science and technology, LED light strip and COB light strip 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 lights and LED lights, explore the differences, advantages and disadvantages of COB lights and LED lights, and compare them in combination with actual application scenarios, and finally give selection suggestions suitable for different scenarios.
LED lights, the full name of which is light-emitting diode lights, are a kind of semiconductor light source. It is composed of a PN junction. When electrons and holes recombine in the PN junction, light emission will occur. LED 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 lights, the full name of which is chip-encapsulated lamp beads, are a new type of lighting source. It is to encapsulate multiple LED chips on the same substrate to form a semiconductor light source to replace traditional LED lamp beads, so as to achieve better light efficiency and higher brightness. COB 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.
COB lights and LED lights are both semiconductor light sources, but they are different in the production of light sources. LED lights are composed of a PN junction. When electrons and holes recombine in the PN junction, light emission will occur. COB lights encapsulate 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. Since COB lights encapsulate multiple LED chips on the same substrate, the light efficiency is higher and the light color is more uniform. LED lamp beads are composed of a PN junction, so the brightness and light efficiency are relatively low.
Advantages and disadvantages of COB lights
Advantages of COB lights:
1. High light efficiency. The light efficiency of COB lights is about 30% higher than that of LED lights, so at the same power, COB lights have higher brightness.
2. Uniform light color. Since COB lights package multiple LED chips on the same substrate, the light color is more uniform.
3. Energy saving and environmental protection. COB lights have high luminous efficiency and can achieve high energy saving effects; at the same time, since COB lights do not require the use of harmful substances such as mercury during production, they are more environmentally friendly during use.
Disadvantages of COB lights:
1. High price. Since the production process of COB lights is more complicated, the price is relatively high.
2. High heat. Since COB lights generate a lot of heat during operation, heat dissipation treatment is required.
Advantages of LED lights:
1. Long life. The life of LED lights can reach more than 50,000 hours, which is longer than the life of traditional bulbs.
2. High luminous efficiency. Although the luminous efficiency of LED lights is lower than that of COB lights, compared with traditional bulbs and fluorescent lights, the luminous efficiency of LED lights is still higher.
3. Saturated light color. The light color of LED lights is more saturated than traditional bulbs and fluorescent lights, and can present more realistic colors.
Disadvantages of LED lights:
1. Low luminous efficiency. Compared with COB lights, LED lights have lower luminous efficiency.
2. Uneven light color. Since LED lamp beads have only one PN junction, the light color is not as uniform as COB lights.
COB light strip and LED light strip are both common lighting equipment, and they differ in the way the light source is made. COB light strip 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 light strips are composed of multiple LED lamp beads. Although the light efficiency is lower than that of COB lights, the life span is longer.
Depending on different application scenarios, the choice of COB light strip or LED light strip should be different. If it is a commercial lighting scene that requires high color requirements, it is recommended to choose COB light strip. If it is an indoor lighting scene that requires long-term work, it is recommended to choose LED light strip.
COB lights and LED lights have different advantages in different application scenarios. The following analysis is made from two aspects: commercial lighting and indoor lighting:
Commercial lighting
Commercial lighting scenes require high color requirements, so it is recommended to choose COB lights. Since COB lights 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 lights is also higher, which can achieve better lighting effects.
Indoor lighting
Indoor lighting scenes require long-term work, so it is recommended to choose LED lights. Although the light efficiency of LED lights is lower than that of COB lights, it is still higher than that of traditional bulbs and fluorescent lights. At the same time, the life of LED lights is also longer, which can meet the needs of long-term indoor lighting.
Recommendations for choosing COB lights and LED lights
Depending on different application scenarios, the choice of COB lights or LED lights should be different. The following are selection suggestions for different scenarios:
1. Commercial lighting scene: It is recommended to choose COB lights, which can meet the needs of higher color requirements.
2. Indoor lighting scene: It is recommended to choose LED lights, which can meet the needs of long-term lighting.
3. Other scenes: Choose COB lights or LED lights according to actual needs.
