DOB, Driver on Board, or Driverless, is commonly known as removing the light source. However, this does not mean that the LED has no light source at all, it is just a new driving method that is different from the traditional Power IC.

DOB LED lights are LED lighting systems (LED bulbs or LED fixtures)

DOB LED Light is LED lighting system (either an LED bulb or an LED luminaire) .


The manufacturing principle of DOB light board:

It combines a light engine with an integrated onboard driver. DOB is short for "driver". In traditional LED lighting systems, the drivers are usually separated from the LED components and fabricated on an FR4 printed circuit board (PCB). This configuration is based on the consideration that the LED driver is primarily designed as a switch-mode power supply. SMPS drivers typically use bulky, expensive, and unreliable reactive components such as inductors and capacitors. Using reactive components requires a dedicated FR4 board that provides sufficient routing layers for component interconnection. In an integrated lighting system, the considerable size of a typical SMPS driver requires sufficient space within the lighting system to accommodate the driver circuitry. In addition, reactive components such as electrolytic capacitors are sensitive to temperature. Remote mounting mitigates these components of thermal stress imposed by LEDs.


What is DOB technology?

Professional LED lighting systems - especially those that control the light - ensure high-quality lighting while reducing energy consumption. Therefore, in order to maintain the high quality and reliability of the lamps, we use driver-based (DOB) technology power adapters.


The DOB lighting driving mode is a new LED driving mode, following the traditional switching power supply mode, which directly rectifies the AC mains into DC and then controls the LED current through the IC, so that the LED can output constant current within a certain range to drive the LED lamp beads to emit light.


DOB flood light (linear flood light) material description:

1. The lamp body is formed by die-casting aluminum, and the vitex + spiral heat dissipation design can efficiently dissipate heat and ensure the service life of the lamp;


2. The surface of the lamp body is treated with outdoor powder, and the appearance is beautiful and generous;


3. Using nano-reflector, the reflection efficiency is as high as 90% or more;


4. High-strength tempered glass is used, with strong compression resistance, high light transmittance and uniform light;


5. 360° adjustable angle mounting bracket, easy to use and firm;


6. The exposed fixing parts are made of stainless steel to ensure outdoor use and durability;


LED lamp beads:

1. The lamp beads are made of high-brightness 3030 lamp beads, with high luminous efficiency and low energy consumption;


2. Luminous efficiency of lamp beads: 160lm/w (the whole light efficiency can reach up to 125lm/w), color rendering index Ra>75;


3. Color temperature value: 3000-6500K;


DOB flood light (linear flood light) application place:

Stadium square lighting, overpass lighting, building lighting, garden landscape, tunnel lighting, outdoor lighting, etc.;


Advantages of DOB floodlights (linear floodlights):

1) It can be made ultra-light and ultra-thin, and the product is beautiful and saves transportation costs;


2) It is easy to produce and can be fully patched, saving labor costs;


3) The defective rate of fully mechanized patch products is low;


4) Since the IC chip and the LED are on the same aluminum substrate, the chip has an over-temperature protection point, which will be protected when the temperature is too high, effectively extending the service life of the LED;


5) No electrolytic capacitor, stable function, low cost and long life;


6) With high power factor, it can achieve real energy saving in practical application;


7) Turn on the light and start instantly without waiting, which is faster than traditional LED.


Advantages of using DOB drivers?

Ultra-thin and ultra-light, saving shipping costs.

Fully automatic SMT, saving labor costs and reducing defective product rate.

Over temperature protection, IC chip and LED are on the same PCB, extending LED life.

Almost no electrolytic capacitor components are used, which is more stable and reduces costs.

Instant on, faster than traditional lights.
