what is COB led strip ?
COB即Chips on Board，意思是芯片直接封装在PCB板上。COB灯带就是将芯片封装在软板上的灯带。芯片多采用倒装芯片，呈线性固晶在PCB板上，然后在芯片表面直接滴一层混合有荧光粉的封装胶水。外观酷似一条拉面粘在PCB板上，芯片发出的光在封装胶体里面通过折射、反射，以及与荧光粉的相互作用，胶体均匀的发出不同颜色，色温的光。
COB stands for Chips on Board, which means that the chip is directly packaged on the PCB. The COB light strip is a light strip that encapsulates the chip on a flexible board. Chips mostly use flip-chips, which are linearly solid-bonded on the PCB, and then a layer of packaging glue mixed with phosphor is directly dropped on the surface of the chip. The appearance is exactly like a piece of ramen sticking to the PCB board. The light emitted by the chip is refracted, reflected, and interacted with the phosphor in the encapsulating gel. The gel uniformly emits light of different colors and color temperatures.
COB灯带与灯珠灯带的区别 (the difference between the cpb led strip and lamp led strip )
①Due to the structural characteristics of the COB light strip, the light-emitting surface is a linear colloid; while the ordinary lamp bead type light strip, its structure is a luminous lamp bead, which is attached to the PCB board. Therefore, the light emitted by the COB lamp belt should be much more uniform, linear, and no spot;
② Since the COB chip is directly bonded to the PCB board, the heat of the chip can be quickly transferred to the PCB board. Therefore, the heat dissipation speed of the chip of the COB light strip is faster than that of the bead type lamp, and the light decay of the COB light strip is smaller and the life span is longer;
③The luminous angle of the light-emitting surface of the COB light bar can reach 180°.
①Home decoration (stairway lighting, hall aisle lighting, lighting decoration, edge trimming decoration);
②Path indication and exterior wall contour decoration, billboard backlighting, advertising signs, etc.;
③Buildings, buildings, pavilions, bridges, park squares and other outlines, building body lighting decoration, various indoor and outdoor lighting projects;
④ Application of decorative lighting for holiday decoration, event venue setting, exhibition venue decoration, exhibition hall decoration, showcase, showcase, props, etc.;
⑤Car body decoration, car interior decoration;
⑥Decorative lighting for hotels, bars, KTVs, nightclubs and other high-end entertainment venues.
安装注意事项 (warm tips on installing )
①The COB packaging colloid is directly exposed to the outside, it is made of silica gel, and the hardness is relatively soft. Avoid contact with sharp objects during installation, so as not to scratch the light-emitting surface and affect the light-emitting effect;
②The colloidal material is easily contaminated with dust and is not easy to handle, so please pay attention to keeping the light strip clean when installing. If it is contaminated with dust, use a cotton swab to stick alcohol and wipe gently.
③ During the installation process of the COB light strip, try to install it in place at one time, and do not have too many repeated tearing and pasting operations. Because the COB light strip chip is directly packaged on the PCB board, the chip size is extremely small, and excessive tearing action will cause the COB light strip chip to die.
