DOB Or Linear, which one better?

#DOB and #linear solutions are widely used in LED lighting products, especially in outdoor floodlights, highbay lights, and street light for fast selling products. And what differences between #DOB and #linear? How to choose the suitable in Flood Light, street light and highbay?

DOB solutions, in generally speacking, just what led driver eletronic parts showed on the PCB. In this way, the current is working in wide voltage 85~265Vac, and what driver can offer so DOB products is nearly same. Like protection measure meet CE LVD and EMC, so this is a safe led product.

Linear solution, not linear light, it just a new or not new but special solution dealing in led driver. IC and varistor is most important part in this solution, which is directly control the current into led chips. But this solutions is only workable in some stable or safe electric working environment. Based on the limited of the IC for voltage sensor only 100-140Vac and 200-240Vac, so the product will be more suitable for European market or US market.

What strength od DOB and Linear? How am I choose most suitable solution once supplier asking? Check below

1.Heat sink

In the same housing, DOB is absolutely more higher internal temperature, cuz its working module is 220Vac though the driver to led chip, and this measure is working on PCB. What about Linear? Linear solution is more stable in temperature cuz the design is let the temperature most focus on the highest heat resistant electronic components. So temperature in same housing, linear is more good performance in heat sink.

2. Wattage

In another words, if the material and housing can working in 85℃, DOB solutions will light up about 30 minutes and then over 105℃, and so to ensure the lifespan, the electronic components will control the current and wattage of led to avoid high temperature. Same will happen in linear but difference is that the linear is all 85℃ in most resistant. There is a perfomance, that you're whole body hot, so we need to let you cold down into 37℃, so from 100W #floodlight to half watt is showing in this 30 minutes. But Linear is you arm or leg is so hot or pain, let we ice cover your leg, so from 100W #floodlight to ensure the lifespan, which will be stable in 85~90W. By the way, this performance only happen in some fast-selling product and end clients is asking price.

3. Lifespan

As you can see above, the lifespan of linear is more longer than DOB, cuz it only working in stable voltage way and led chips is working in good environment.

4. Safety

With the double IC solution develped, the linear solution is more suitbale to work in Brazil market also, cuz the product can work in 100-140& 200-240Vac both. However, current directly to PCB, and this is absolutely dangerous way once the working environment is really problem happen...like surge, and linear is only 0.5kV. DOB, we can say that there is already led driver, which will protect you and the product also.

Let we in conslusion, #dob solution is more suitable for product with wide voltage requirement and stable way in led lighting. #linear is more suitable for some country already with stable working environment and also great watt performance and heat sink.

Protect Electrical Components:
The electrical components of solar street lights are susceptible to damage from sand and dust ingress. To safeguard these components:

Seal electrical connections: Apply a weatherproof sealant or silicone to seal the electrical connections, such as wire junction boxes, to prevent sand and dust infiltration.
Use protective covers: Install protective covers or enclosures for sensitive components like batteries, controllers, and inverters. These covers shield the components from direct exposure to sand and dust while allowing proper ventilation to prevent heat build-up.
Utilize surge protection devices: Install surge protection devices to safeguard against power surges and voltage fluctuations that may occur during sandstorms. These devices help prevent damage to the electrical circuitry of the solar street lights.
Regular Maintenance and Repairs:
Implement a proactive maintenance schedule for your solar street lights. Conduct routine inspections to identify any signs of wear, loose connections, or damaged components. Promptly address any issues by repairing or replacing the affected parts. Regular maintenance ensures the longevity and optimal performance of your solar street lights, even in challenging weather conditions like sandstorms.

Educate and Train Personnel:
If you have a dedicated maintenance team responsible for solar street lights, ensure they are adequately trained on the specific measures and protocols for maintaining lights during sandstorm weather. Provide them with the necessary knowledge and equipment to handle cleaning, inspection, and minor repairs effectively. Encourage a culture of proactive maintenance and prompt reporting of any issues that may arise.

Conclusion:

Maintaining solar street lights during sandstorm weather is crucial for their longevity and performance. Regular cleaning and inspection, reinforcement of fixtures, protection of electrical components, and scheduled maintenance play pivotal roles in safeguarding the lights against the adverse effects of sandstorms. By implementing these measures and investing in proper care, you can ensure that your solar street lights continue to illuminate streets and public spaces efficiently, even in the face of challenging weather conditions.

Remember, protecting and maintaining solar street lights not only ensures their optimal performance but also contributes to sustainable and energy-efficient lighting solutions for our communities.
