    8 choices to a cost-effective LED grow light  

     

    Smart design delivers longlasting performance - Part 1

     

    To grow crops successfully and cost-effectively with LED grow lights, your LED system must be designed to perform reliably in the harsh conditions of your greenhouse environment. In part 1 of a 2-part series, we explain 4 smart design choices we’ve made for Philips GreenPower LED toplighting compact that give you peace of mind. With this proven design, your Philips LED lighting system is guaranteed to work reliably for many years and much more than 36,000 hours of intensive use, while being easy to maintain and clean. 

     

    Smart design #1: Aluminum body and passive cooling for better heat management

     

    LED lighting generates much less heat than high pressure sodium (HPS) lighting, but it still generates heat. So the housing of your LED module needs to efficiently manage excess heat. Otherwise the light output of your LEDs will decrease dramatically. There are two choices to keep the LED module cool. Active cooling with water or a fan. Or passive cooling that uses the material of the housing to dissipate the heat from the LEDs. Signify opts for passive cooling because active cooling introduces extra parts to the product that can cause the LED system to fail. For instance, water cooling can leak and has to keep running to avoid algae formation even when lights are off, so it uses more energy. 

     

    That’s why we’ve used a cast aluminum body for our LED modules to create a heat sink. It has large cooling vents that promote air flow and make it easy to clean the module. Small vents can collect dust and moisture that lower the module’s cooling capacity and make it difficult to clean. Our large cooling vents let water easily run off during cleaning and reduce pool forming that can produce moisture in the product. The top of the module and all of the cooling vents are rounded to prevent moisture from standing.

     

    The cast aluminum body has been milled to create a completely flat surface. The Metal Core Printed Circuit Board (MCPCB) is attached to that milled surface, but we still fill even the smallest spaces between the milled surface and the MCPCB to optimize the thermal resistance. In fact, the LED toplighting compact module has an IP66 ingress protection rating. This means it can withstand dust and water from coming in. The design of the toplighting compact thus ensures that the grow light delivers very high light output, consistently over time, while being easy to clean.

    Smart design #2: Standard connector for easy, cost-saving switch to LED 

     

    The LED toplighting compact is designed with a Wieland connector and adapter that fits existing HPS connectors, so you can easily replace your HPS lighting with our LED lighting, using your existing HPS set-up and trellis. We use standard Wieland connectors because they are a dependable and proven product in the horticulture industry. In fact, 85% of our current HPS installations are also equipped with Wieland connectors. You can replace HPS with our LED lighting as long as the power load of the connection is not higher. For example, 1040 W HPS can be replaced by an LED product of max 1040 W without any problem. Because the LED module is mounted under the trellis the connector is placed on the side of the housing, allowing you to easily access and mount the cable or a splitter.

     

    An important advantage of our LED toplighting compact is that it does not have an inrush current; this is the instant surge of current drawn by an electrical device when first turned on. That means you do not need to change your breakers when switching to the LED toplighting compact. Many LED products have high inrush currents that can overload a standard breaker, meaning you have to modify your circuit breaker cabinet to use them, which can be very costly. 

    Smart design #3: Driver in a separate compartment 

     

    When you turn the LED module on, the air around it warms up. And when you turn it off, the air cools down. You want to do this in a controlled manner, otherwise as the module cools down, moist air will be drawn into the module which can corrode electronic components over time. To prevent this, we’ve placed our driver in a separate compartment and sealed it with a gasket to create an enclosed component. A gore-tex vent on the compartment works just like self-breathing raincoat, allowing air to circulate but preventing moisture from coming in and depositing on the driver. Our drivers are developed in-house and meet the most stringent standards to protect against sulfur and safeguard electronic performance.

    Smart design #4: Powder coating provides solid resistance to corrosion and flaking


    Our aluminum body has a white powder coating. Why powder coating? Unlike paint which is very sensitive to chemicals, powder coating is applied electrostatically and then cured with heat or UV light making it much more robust. It costs slightly more, but pays for itself in the long run. Your powder-coated LED module resists chemicals used in the greenhouse that can erode paint and cause corrosion. It also looks great and no paint flakes fall off after a few years of use.
