What is dob in lighting?

A DOB LED light is an LED lighting system (either an LED bulb or an LED luminaire) that contains a light engine with an integrated on-board driver. DOB is short for "driver-on-board". In standard LED lighting systems the driver is normally isolated from the LED assembly and manufactured on an FR4 printed circuit board (PCB) (PCB). This architecture is based on the assumption that LED drivers have been dominantly developed as switching mode power sources. SMPS drivers often make use of large, costly, and unstable reactive components such as inductors and capacitors. The usage of reactive components demands a specific FR4 board that offers enough routing layers for component interconnects. In an integrated lighting system, the large bulk of a typical SMPS driver generates a requirement for a sufficient area inside the lighting system in order to fit the driver circuit. Furthermore, reactive components such as electrolytic capacitors are temperature sensitive. Remote installation may ease these components of thermal strains otherwise imposed by the LEDs.

A DOB lighting system employs solely solid-state driver components which are available in surface-mount packages capable of being constructed on circuit boards with a single-sided copper architecture. This makes it feasible to install driver components on a metal-core printed circuit board (MCPCB) where LEDs are placed. Typically, the driver is designed as a linear power supply. Since there is no high-frequency switching, electromagnetic interference (EMI) is almost nonexistent in linear power supply. The total absence of EMI radiation permits linear power supplies to be constructed with a greatly reduced component count. The reduced circuit parts count and tiny form factor of circuit components create a small footprint of the driver, which introduces little influence on the LED assembly when it comes to photometric performance. The drive current is controlled by tiny driver ICs without utilizing electrolytic capacitors. The weakest component with the lowest life expectancy decides the life of the driver. The elimination of electrolytic capacitors corresponds to greatly increased driver dependability.

DOB light engines, however, have their limits. Linear supplies are fundamentally inefficient. The headroom voltage is dissipated as heat which imposes an extra thermal strain on the co-located LEDs. The absence of flicker is vital for any lighting system but may be problematic to DOB lighting systems due to the existence of huge waves in the DC current given to LEDs. The LEDs in a DOB light engine are not only strained by the increased thermal load supplied by the driver but are also prone to electrical overstresses since the driver has limited capabilities of absorbing voltage surges that may be present on the AC line. The output circuit is not galvanically insulated from the mains. In this instance, all-metal connections must be appropriately separated to give protection against electric shock.

What are the advantages of driverless LED Light technology？

1. These driverless LED lights are more cost-effective to produce. The expense is minimized, and the system needs relatively little maintenance.

2. It is suitable for usage in high bay lights because of its enhanced flicker index. Additionally, the workplace, room, and education sectors use driverless AC LED lights.

3. When the LED driver is removed, the reshaping function is enabled. LED products are available in a variety of forms and sizes.

4. Another excellent characteristic of driverless AC LED lights is their ease of installation.
