Before we installed the lights for some occasions, we should make sure different lighting tool for a different place, such as lights for hotel lighting, restaurants lighting and fashion shops lighting application. Some ideas about choosing best COB light for the suitable place following :
CCT & CRI
According to the various environment choosing the right CRI,CCT and accurate light source. In the Parting lot, Shopping Mall, Living room, Exhibition hall, the application should be use high lumen COB light with CCT from 3000k to 5000k,Ra≥80.
Lighting Power & Light-emitting Angle
The power and light-emitting angle of the luminaire will be determined on the basis of the design of the application scenario and layout, as well as the number of lights will be determined by it. The height and the illumination requirements of the ground and work surface also will affect the power and light-emitting angle of the luminaire used. After the above items are determined, the following part is to choose the mold of COB. On the basis of large angle with large light-emitting surface COB, small angle with small light-emitting surface COB, it is more suitable to choose 30W below 15°for 9MM luminous surface COB, 20W is suitable for 6MM, 15W is suitable for 4MM and 10W is suitable for 3MM. Among them, both 4MM luminous surface COB and 3MM luminous COB can reach angles below 10°
Because the heat dissipation of the internal chip of the COB is closely related to the size of the light-emitting surface, so the COB current density of the small light-emitting surface requires higher heat dissipation conditions, and the heat dissipation requirement is relatively more demanding for the COB current density of the large light-emitting surface is relatively small. Therefore, in case of high power and high current Under heat dissipation, it is necessary to consider the use of a large light-emitting surface as much as possible to ensure light efficiency and reliability.
COB brand & Optical Matching
The choice of COB brand, each brand has its own strengths, some brands are strong and terminal recognition is high, some product lines have full power, some have good color consistency, and some have high light efficiency. Choosing COB should be based on the positioning of its own lighting brand. For example, when doing circulation lighting and engineering, it is necessary to choose different COB products for positioning. The optical matching of the product is necessary while choosing the COB. Which work should be carried out at the same time? The quality of a luminaire and the effect of on-site application are largely due to the matching decision of COB and optical devices. It is very important to ask about the most suitable optical device combination for each model of each COB brand. The best course is to develop optics for each luminaire for the project.
Heat Dissipation Effect
The heat sink equipped with the luminaire tests whether the overall heat dissipation design is reasonable. If it is unreasonable, you need to adjust the heat dissipation structure or reselect the COB and optical solutions.
