LED grow lights

For LED grow lights, the most important part is the PCB board, which carries LEDs and dissipates thermal quickly. If you plan to develop an LED grow light brand, or if you want to make custom LED grow lights for your farm or indoor bases, this post by the one-stop LED grow light PCB manufacturer PCBONLINE will guide you through.

Part 1: Wavelengths of LED Grow Lights

LED grow lights are designed for plant growth and mainly shed red and blue light. The red light in the wavelength of about 700nm helps plants to bloom and bear fruits, while the blue light in the wavelength of about 400nm promotes plant growth.

Different plants have different demands for red and blue light. For plants whose stems and leaves are what we want, such as lettuce, we can increase the portion of blue light LED beads in the PCB design. For plants whose fruits are what we want, such as tomatoes, we can increase the portion of red light LED beads in the PCB design.

Generally, the ratio of red and blue light of LED grow lights ranges from 9:1 to 6:1.

For the eyes' comfort, a small amount of green light LED beads are also added to the PCB design.

Besides red/blue LED grow lights, there are other types - full spectrum LED grow lights, which imitate sunshine and serve as supplemental lighting.

LED plant lights

Compared with traditional grow lights, such as metal halide bulbs and high-pressure sodium lights, LED grow lights save independent rectifiers and can directly power on. What's more, LED grow lights greatly save energy.

The wavelength and light color of the LED grow lights are custom-designed on the LED PCB assembly. By designing the LED beads and the LED PCB that provide RGB (red, green, and blue) and RGBW (red, green, blue, and white) custom light color options, you can have the LED grow lights manufactured in your brand suitable for the plants you or your customer want to grow.

At the EMS (electronic manufacturing service) provider PCBONLINE, professional engineers can design the LED growth light PCB with custom power, wavelength, color temperature, and lumen for the plant growth that you want. After PCB design, PCBONLINE manufactures the samples and tests the light source with a report for you to review. When everything is okay, PCBONLINE provides bulky production of LED grow lights for you.

Part 2: LED Grow Light PCBs

You may worry about the drop in LED working efficiency when the temperature increases. But you don't have to, if your LED grow lights use quality PCBs that can dissipate thermal quickly.

Most of the LED grow light PCBs are aluminum-based. Aluminum PCBs from PCBONLINE have a thermal conductivity of 1W/mK to 9W/mK. This thermal conductivity is enough for the needs of most LED grow lights. From PCBONLINE, aluminum PCBs for LED grow lights can be single-sided, double-sided, flexible, single-layer, and double-layer.

However, if you want a better thermal conductivity of the LED grow lights, you can also choose ceramic PCBs for your design. Without a dielectric layer, ceramic PCBs have better thermal dissipation than aluminum PCBs. From PCBONLINE, you can have alumina substrate PCBs and aluminum nitride PCBs manufactured.

Besides aluminum PCBs and ceramic PCBs, from PCBONLINE, FR4 PCBs, copper-core PCBs, and flexible PCB LED strips are also available for LED grow lights.

One-Stop LED Grow Light PCB Manufacturing - From Initial Idea to End-Product Assembly

If you have designed PCBs for your LED grow lights and want to make them into reality, or if you plan to have LED grow lights manufactured for your farm but without a PCB design, you can work with the LED grow light PCB manufacturer PCBONLINE.

PCBONLINE, a one-stop advanced PCB manufacturer founded in 1999, has two large PCB manufacturing bases and one PCB assembly factory. PCBONLINE provides one-stop LED grow light PCB manufacturing from your initial idea to bulky production and end-product assembly.

Here are reasons for you to let PCBONLINE manufacture your LED grow light PCBs:

    • Our engineer can custom adjust the LED wavelength best for your plant growing.
    • From PCBONLINE, LED grow light parameters can be tailored, such as light colors and lumen.
    • We already achieved industry 4.0 aluminum PCB production for LED grow lights, and the cost is only $30/㎡ for bulky production.
    • If you don't have an LED grow light PCB design, we can provide free open-source solutions.
    • One-on-one professional engineering support throughout your project until you get what you want.
    • PCBONLINE provides one-stop LED grow light PCB solutions, from prototyping/sampling to bulky production.

If you have any needs or questions about LED grow light PCBs, please feel free to contact PCBONLINE by email at info@pcbonline.com.

Conclusion

It is the PCB that enables LED grow lights to work for a long time and dissipate thermal quickly. If you want to have LED grow lights manufactured or look for turnkey LED grow light PCBs, don't miss the 23-year-old source factory PCBONLINE.
