The difference between cob light strips and led light strips

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, etc., 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.

1. Light source structure

 COB (Chip on Board) light strip is a lamp that integrates multiple LED chips on a substrate. Multiple LED chips on the substrate are arranged side by side to form a whole, and the light-emitting area is continuous and uniform. The LED (Light Emitting Diode) light strip arranges single LED chips side by side on the light strip. Therefore, the light source structure of COB light strips is more compact and integrated, while the light source of LED light strips is relatively more dispersed.

2. Brightness

 Because the light source structure of COB light strips is more compact, when multiple LED chips work at the same time, the light-emitting area is larger and the brightness is higher. As the light source of LED light strips is relatively dispersed and the individual LED chips are small, their brightness is relatively low. Therefore, when higher brightness lighting effects are required, it is more appropriate to choose COB light strips.

3. Energy efficiency

 The lighting effect of COB light strips is relatively better, the light is uniform, the reflection effect is stronger, and the energy efficiency is higher. Due to the compactness of its light source structure, COB light strips can better control the propagation direction of light and reduce energy loss during the lighting process. However, the energy efficiency of LED light strips is relatively low due to the scattered light sources during the lighting process.Therefore, while pursuing energy efficiency, choosing COB light strips can save energy and reduce lighting costs.

4. Price

 Because COB light strips require higher production processes and have better lighting effects and energy efficiency, their prices are relatively high. The price of LED light strips is relatively low due to their simple production process. Therefore, when the budget is limited, it may be more economical to choose LED light strips.

Five application scenarios of COB lights and LED lights

 COB lights and LED lights have different advantages in different application scenarios. The following is an analysis 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.

 To sum up, there are obvious differences between COB light strips and LED light strips in terms of light source structure, brightness, energy efficiency and price.  COB light strips have the advantages of compact light source structure, high brightness and high energy efficiency, and are suitable for occasions that require high brightness lighting effects and energy saving. LED light strips have the advantage of relatively low prices, and can meet certain lighting requirements under specific lighting needs. Therefore, when choosing light strips, you should consider comprehensively based on specific needs and budget to make the most reasonable choice.
