LED Lights COB new tech for Office Home Interior Decoration Bangladesh
The greatest power densities on the smallest space are often the basis for unique selling points of various products on the market. These criteria can be realized by the (Chip on Board ) COB LEDs technology.
Direct contacting of the semiconductors (LEDs) on PCBs allows for optimal thermal management, high packaging density and thus long-lasting and high-performance COB LED modules.
COB LEDs have some technical advantages, such as thermal resistance, larger cooling area, better lighting effect and high light efficacy. That can increase lighting area 10 times more and no uncomfortable glare.
For small size chip, some famous LED chip manufacturer can reach 249lm/watt @ 20mA. And big size LED chip can only reach 161lm/watt @350mA. The light efficacy decrease when chip size is bigger. Also when LED driver increase current to LED, the light efficacy per watt is even low. COB with small size chips is a trend of LED light source package.
