What is DOB flood light?

February 28, 2023

Dear friends, you must be wondering what is DOB?

"DOB" is the abbreviation of "Driver on board" in English, which means that the power supply is on the board. The so-called DOB is the AC high-voltage light source power supply, which means integration. The so-called "de-power supply" in the market is a false proposition and an inaccurate statement.

The DOB lighting drive mode is a new LED drive mode in addition to the traditional switching power supply mode, which directly converts 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 floodlight (linear floodlight) material description:

1. The lamp body is made of die-cast aluminum, and the wattle + 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%;

4. High-strength tempered glass is adopted, which has strong compressive performance, high light transmittance and uniform light;

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

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


LED lamp beads:

1. The lamp beads adopt high-brightness 3030 lamp beads, with high light efficiency and low energy consumption;

2. Lamp pearl effect: 160lm/w (the whole light effect can reach up to 125lm/w), color rendering index Ra>75;

3. Color temperature value: 3000-6500K;

DOB floodlight (linear floodlight) application places:

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 completed in full patch, saving labor costs;

3) The defect 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 prolonging the service life of the LED;

5) No need for electrolytic capacitors, stable function, low cost, and long life;

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

7) Turn on the light and start instantly, no need to wait, faster than traditional LED.
