DOB Street Light

LEDs generally require a stable power supply to turn on. The on-screen driver, or DOB, means removing the power supply or light source from the LED. However, this does not mean completely removing the driver or light source from the LED. Instead, in the DOB LED light, only the external driver is removed, and in fact, the drive is installed on the same board as the DOB LED, fully compressed, and improved and simplified with other technologies.

DOB lights are usually completed in two categories and divided into several steps. In the first model, the current is drawn from a square pulse from the input and goes to other parts; Features of this one-step model include low price, less complexity and lower; This model has much weaker electrical and optical properties than multi-stage models; Among them, we can mention the harmonics above 20% low efficiency; But the second category, which is considered a few steps; The shape of the input current is similar to sine waves, which makes this function much better. Among these specifications, we can mention the 20% better harmonic harmonics and less filters.

Other features of DOB lights of Noorfan Espadana Engineering Company include the following:

1- DOB lights use linear IC power supplies that are commonly used for indoor use. For this reason, these models of lights are anti-lightning shock and are generally not recommended for exterior lights such as street lights.

2- Lower efficiency of DOB lights and cost reduction

The use of IC linear boards for this type of product has reduced the efficiency of LEDs and ultimately uses 70% of the capacity of LEDs to produce light and waste the rest.

3- Instant lighting, faster than ordinary lights.

And one very important thing to keep in mind when using DOB boards is that because both the LED and the AC to DC power module are on the same board, of course more heat is generated and a heatsink is needed. It has a stronger heat dissipation and not using a suitable heatsink has shortened the life of the light.
