Model specifically designed for SMD-LED maximizing Heat Dissipation efficiency
As LED lighting been rapidly adopt in commercial and industrial application in the past 10 years. Based on our customer’s feedback and our own evaluation:
High efficiency
It is known by fact that lower LED temperature increase the luminous efficiency LED, therefore a good heat dissipation of LED is very important. When LED driver is installed in the light fixture’s structure. A higher efficiency LED driver consume less power for converting AC power into DC power. Therefore, it will emit less non-useful power inside the lighting fixture, thus reducing the temperature rise of lighting fixture. By doing this we can maintain the light output and reduce the negative impact because of higher temperature and extend LED light’s lifetime.
High reliability
especially like the led driver of LED Flood light, generally they are installed outside, of course, maybe separate from the light fixture as well. such as hidden in the light pole or installed on the fixed bracket. We must comprehensively think of its waterproof, aluminum housing and any other performances. High reliability led driver is not easy to break and help to reduce the cost of maintenance.
High power factor
For commercial and industrial outdoor lighting, it is very common for lighting manufacturer to registered product with Design Lights Consortium. One of the requirement for Lighting Fixture certified as DLC listed is power factor must large than 0.9. The power factor of an AC power system is defined as the ratio of the real power absorbed by the load to the apparent power flowing in the circuit, and is a dimensionless number in the closed interval of −1 to 1. In an electric power system, a load with a low power factor draws more current than a load with a high power factor for the same amount of useful power transferred. The higher currents increase the energy lost in the distribution system, and require larger wires and other equipment the power factor is the load requirement of the power grid and is an important technical data of power system. Therefore, we only use LED driver with power factor higher than 0.9.
Constant Current and Constant Voltage driving methods.
It is common to see there are two type of LED driving method, one is Constant current and the other one is Constant voltage, what make it difference is the way in which they deliver the power. LED drivers are the main driving force that provides and regulates the needed power to make sure the LEDs operate in a safe and consistent condition.
Constant current LED drivers are designed for a selected range of output voltages and a fixed output current. Constant current driver requires a designated supply of current usually specified in (mA) or (A). These drivers vary the voltage along an electronic circuit which allows current to remain constant throughout the LED system. Higher current ratings do make the LED brighter, but if not regulated, the LED will draw more current than it is rated for. Thermal Runaway refers to excess current beyond the LEDs maximum drive current which results in drastically lower LED life-spans and premature burn outs due to increased temperature. A constant current driver is the best solution to drive high power LEDs as it maintains a consistent brightness across all LEDs in-series.
Constant voltage drivers are designed for a single direct current (DC) output voltage. It is quite common to have an 24VDC or 36VDC. An LED light that is rated for constant voltage usually specifies the amount of input voltage which needs to operate correctly. A constant voltage power supply receives standard line voltage. For USA’s residential application, it is usually 120V AC to 277V AC. This is the type of power that is typically output from the wall outlets in the home. Constant Voltage Drivers switch this alternating current voltage (VAC) to a low direct current voltage (VDC). The driver will always maintain a constant voltage no matter what kind of current load is put on it. Most often, constant voltage drivers are implemented in under-cabinet lights and other LED flex strip applications but it is not limited to those categories.
It sometimes called as surge protector, it is an indispensable device for electronic equipment to protect against lightning or surges. The function of the surge protector is to use components such as gas discharge tubes or varistors to discharge the transient over voltages such as strong lightning or surge currents into the power or signal transmission lines into the earth, limiting the voltage range of the equipment or system within the range that can withstand, the protected equipment or system will not be damaged by the electric shock (voltage surge). It is very common for outdoor lighting driver to have build in minimum 4kV surge protection.
Internet has not only created abundance of convenience in today’s society, it has also created a lot of issues. With thousands of Floodlights over the counter and over several online platforms, how do you make the right choice in buying the right type of Floodlights?
Today we compiled 3 tips on which Lights are the best choice when browsing through online, what types are best for which application, and what types are best to avoid:
1. Lowest Price doesn’t always mean the best
With the convenience of Amazon/Wallmart and many online platforms, which allows anyone to be able to offer LightingProducts, however from time to time, it will also mean a lot of these product have not gone through proper validation. This could mean not going through proper aging, thermal testing, and all these could contribute to early life failure, so buy looking for the cheap product could result in having to replace the product again in 2-3 years. If you are buying expendable products like torch etc, then it would not matter, but having products like a lighting fixture, for example: floodlights, where it requires a large amount of labor to install, then go with companies that know what they are doing. With companies has been doing lighting for over 30 years now, we’ve experienced it all and know how to build quality lights, as well as conducting through the proper validation. A General Rule of thumb: when your dividing the Fixtures Lumen output by the dollars sold, if the Lumen per dollar is over 500lumens/dollar, then chances are there is some falsified information of the product and that it should be avoided.
2. Choosing COB/SMD can make a difference in terms of the application:
Are you looking for a simply wall wash flood? A bullet flood to shine a flag? An Area Light to cover the Parking lot? Whilst Lighting Product can be categorized into different application, the LED itself can also make a big difference in the longevity and the Light angle that comes out. For example, COB(Chips on Board) type LED Fixtures offer a more concentrated beam angle, which is generally Ideal for Spot Light(pin pointing on certain spot) However we also see Spot Lights today utilizing SMD for a more thermal dissipation alternative. For general Wall wash with no requirement for Beam Angle, we would generally look at Utility flood for maximum coverage in terms of the area. If you are unaware of what type of Lighting Distribution or type of lighting suitable for what application, please speak to your local Electrical Distributor or lighting specialist, or can contact us at info@firstlighting.com where we can provide solutions for your requirement.
3. Different Mounting Options and what’s best for you
With every Lighting fixture, there is several ways of Mounting Options to install the Lighting Fixture, be sure to choose the right one that’s most suitable to the areas you will be installing it on. Whether it be Wall Mount(installing onto a Vertical Wall surface by connecting to a junction box of Conduit Pipe) Yoke/Trunnion Mount(a U-Bracket to allow Fixture to be able to adjust angle and lighting direction) or Knuckle/Slip fitter(installing onto Pole Mount or Pipes). Choosing the right Mounting Option will mean allowing the Fixture to be firmly installed and can prevent any loosening due to external environments. This will ensure the longevity of the Fixture in Operation.
