High-power LED floodlights mainly refers to the power in a single power of more than 1W for high-power. Ordinary lights 0.05w or less.
Power LED floodlights is less power consumption, low power consumption more.
When consumers buy LED lamps, manufacturers often see the high-power or small power logo, then the main difference between high-power and low-power What is the difference? Your ideal lamp should use high-power lamps or small power?
Zhihai LED lighting manufacturers tell you more about this question.
Standard Versus High-Power LEDs
To illustrate how a standard LED array can provide significant design process, cost, and real-estate savings compared to a high-power LED, consider a theoretical application that requires 90 lumens of light output or brightness. This brightness can be achieved by using a single 1-W high-power LED or an array of six standard LEDs (Fig. 1).
The design process required for a standard LED array can be far simpler than that required for a high-power technology because of greatly simplified thermal-management considerations. In our example, the 1-W LED will be driven at 350 mA of current compared to just 120 mA of current for the array of six standard LEDs.
The high-power technology will require a heatsink and metal-core printed-circuit board (MCPCB) to ensure the junction temperature isn’t high enough to cause a loss in efficacy, a decrease in life hours, or color degradation. Standard LEDs don’t require heatsinks, an MCPCB, capacitors, or resistors, so they’re easier to design, test, and manufacture. This simplified process not only saves time and money during the manufacturing process, it speeds up time-to-market as well.
LED lamp beads of different power
As the name implies, high-power single-bead lamp is 1W or more, or COB is a kind of integrated light source, which can make even light, no dead light, no plaque, soft fiber and no glare. High-power LED flood light, single LED power can do more than 200W.
Low-power LED lights, the general is the use of SMD lamp beads, including these types: 5050 lamp beads, each 0.2W, 3528 lamp beads, each 0.06W, 3014 lamp beads, each 0.01W, 5630 lamp beads, Each 0.5W, 5730 lamp beads, each 0.5W.
The thermal management needs of a high-power LED can add significant cost to the LED. The most costly design addition is the heatsink, which can be made from a variety of metal materials from relatively inexpensive aluminum to more conductive but also more expensive materials such as copper and silver. These expensive materials can add between $1 and $10 to the cost of the high-power product, a cost that isn’t applicable to standard LED devices.
Similarly, high-power LEDs also require the use of an MCPCB to serve as another passive cooling technique for controlling junction temperature. These boards dissipate heat more efficiently than the more affordable FR4 PCBs used with standard LEDs because materials in MCPCBs have better thermal conductivity. However, they can be up to five times more expensive than the FR4 PCBs. The ability to use a more affordable FR4 PCB, eliminate the need for an expensive heatsink, and simplify design considerations can lead to cost savings up to 60%.
Real Estate Savings
Finally, when there are significant internal space limitations in a device, a standard LED will again often be the best choice. As mentioned, high-power LEDs require the addition of heatsinks, a bulky cooling technology overall. Their primary task is to create more surface area to be cooled by convection and radiation. A larger surface area can help reduce heat more effectively, but it also adds bulk to the high-power LED, which can create design obstacles in smaller spaces and smaller products.
So how is it possible to figure out if a high-power LED or some combination of one or more standard LEDs is more suitable for a particular application? For some designs, the choice is clear.
Smaller, battery-operated, or portable devices such as consumer electronics, accent lighting, and standard indicator lights have long used standard LEDs and will likely continue to do so. Along the same line, some areas will continue to use high-power LED technology including general outdoor lighting, large area indoor lighting (track lighting, bulb replacement), and automotive forward lighting.
Other applications, though, fall into a gray area and may take careful consideration, such as small-space lighting like glove compartments and cabinets, interior and exterior signage, dental and medical devices, and industrial control status indicators.
Making The Right Choice
The best way to make the right LED choice for your product is to speak with your supplier, who should have a wide catalogue of both standard and high-power LEDs. Rather than pushing you toward a particular cookie-cutter technology, the supplier should take the time to truly understand your unique technology needs and specific application requirements.
