Using LED light tape

Backlighting is a great way to display stained glass, creating an even and controlled environment both during the day and at night. LED light tape is a popular method for backlighting stained glass. It is important to ensure that the polarity of the connector wires and tape light are consistent to maintain even light coverage. The standard length for LED light tape is 16 feet.

When using LED light tape, it is recommended to use a remote-controlled device to adjust the lighting. This allows for control over the colour and intensity of the light. The remote receiver can be placed outside the frame box by cutting two small slots in the bottom of the frame, ensuring it receives the signal.

To achieve the desired lighting effect, the LED light tape can be cut to the required length and connected to other pieces using connectors. Before gluing the lights in place, it is important to check their functionality. The tape lights can then be glued to the back of the frame box, with plywood or Gorilla Glue gel recommended for a secure and neat finish.

For a neat finish, it is recommended to avoid using glue or metal angles for the final piece. This makes it easier to change the diffuser if needed. Additionally, a white acrylic diffuser can be inserted to enhance the lighting effect.

Overall, LED light tape is a versatile and effective option for backlighting stained glass windows, offering customisation and control over the lighting to showcase the stained glass artwork.

Creating a light box

Materials and Equipment:

  • LED Flat Panel Ceiling Light Fixtures (available at hardware stores such as Home Depot, Lowes, and B&Q)
  • A workbench with a surface that can accommodate the light fixture
  • Electrical box
  • LED light tape, preferably dimmable with a remote (16' is a good standard length)
  • Oak for framing (1"x3")
  • Plywood for enclosing the back
  • White acrylic diffuser
  • Gorilla Glue gel
  • Piano hinges
  • Connectors

Construction:

First, cut a hole in the workbench surface to accommodate the electrical box. Then, assemble the LED Flat Panel Ceiling Light Fixtures to create a large or small light box, depending on your needs.

Next, create a frame for your stained glass. The inner dimension of the light box should be the same or slightly larger than the inner dimensions of the frame. The frame can be made from oak, with a groove for the glass set about 1/4" back from the front.

Now, attach the stained glass to the light box using piano hinges. This will allow you to open the frame and access the lights if needed.

After that, cut and connect the LED light tape to fit the dimensions of your light box. Use connectors to join the pieces and help the tape stay flat. Check the lights before gluing them down with Gorilla Glue gel.

Finally, enclose the back of the light box with plywood. You can also add a white acrylic diffuser to prevent the lights from being visible and create a uniform lighting effect.

Your light box is now ready to use! You can control the lighting intensity and colours using a remote control device.

Alternative Methods:

If you prefer a simpler approach, you can construct an easel in front of a window to view your stained glass. Alternatively, you can use a pre-made light box. Many printing companies have high-quality light boxes that they may be willing to part with.

Using a remote control device

Backlighting is a great way to display stained glass, giving it an illuminated, 3-dimensional look. It can be used to showcase a stained glass window or panel and can be installed in both traditional and modern settings. The number of foot candles needed to backlight a stained glass window will depend on the size and complexity of the window, as well as the desired brightness and evenness of lighting. One way to achieve backlighting is by using LED light strips with a remote control device.

To install LED light strips with a remote control device, follow these steps:

First, determine the size of the LED light strip you need. Measure the length and width of the stained glass window and choose an LED light strip that is long enough to cover the desired area. You may need multiple strips or a longer strip for larger windows.

Next, prepare the LED light strip for installation. Unroll the strip and attach double-sided tape to the back, ensuring that the adhesive side of the tape is facing the glass. If your LED light strips do not have an adhesive backing, you may need to use another method to attach them, such as screws or soldering.

Once the LED light strip is prepared, attach it to the back of the stained glass window, ensuring that it is centred and secure. Make sure all connections are secure and that the light strip is flush against the glass.

Now, you can use the remote control device to control the lighting. Depending on the type of LED light strips and remote control device you have, you may be able to control the colour and intensity of the lights. This will allow you to adjust the lighting to achieve the desired effect and brightness.

Additionally, you may want to consider installing a diffuser panel in front of the stained glass window. This is a piece of frosted or textured glass that helps to diffuse the light, creating a soft, even glow and reducing the visibility of individual lights. The diffuser panel can be secured in a frame or light box, which will also contain the lighting system and stained glass window.

By following these steps and using a remote control device, you can achieve the desired level of backlighting for your stained glass window while also having the convenience of remote control. The exact number of foot candles needed will depend on your specific setup and preferences, but with some adjustments and testing, you should be able to achieve the desired lighting effect.

Arranging the window and exterior shade

When arranging the window and exterior shade for backlighting stained glass, there are a few key considerations to keep in mind. Firstly, ensure that the frame and glass or acrylic panes fit properly by taking precise measurements. This is crucial for achieving a neat and secure fit. Next, decide on the lighting setup that best suits your needs and preferences. One option is to use LED light tape, preferably dimmable with a remote, to provide backlighting for the stained glass. The standard length recommended for the LED light tape is 16 feet, and it can be cut and connected to other pieces using "connectors." These connectors also help the LED tape stay flat.

Another option is to create a light box by building a wooden frame without a diffuser. This involves creating a groove for the glass about a quarter of an inch back from the front and a dado about three-eighths of an inch deep on the back. The final piece is a quarter-inch backboard, and everything behind the glass should be painted white. The inner dimension of the light box should be the same or slightly larger than the inner dimensions of the panel frame to ensure a proper fit. It is also important to ensure that light does not leak out from the back of the box.

When attaching the framed stained glass to the light box, use two piano hinges to allow for easy access in case of any issues with the remote receiver, transformer, or tape. Before gluing the lights down, check that they are functioning properly to avoid unevenness due to polarity changes at the connector. Gorilla Glue gel is recommended for adhering the tape lighting to the back of the frame box as it is less messy than liquid glue.

Additionally, consider the power source for the lighting setup. While a traditional power cord can be used, a remote-controlled device offers a cordless alternative, providing simple control over light colours and intensity. Solar-powered lights are another option, especially if the stained glass window is located outdoors. These suggestions provide a starting point for arranging the window and exterior shade to effectively backlight stained glass windows.

Adding a diffuser panel

There are various types of diffusers available, including acoustic diffuser panels and sound absorbers. Acoustic diffuser panels are designed to scatter sound waves, while sound absorbers, made of dense and porous materials, allow sound to enter but not escape. Sound absorbers convert sound energy into heat energy, reducing its impact.

When adding a diffuser panel to backlight stained glass, it is crucial to consider the type of diffuser and its placement. For example, a translucent vinyl diffuser can help distribute light evenly behind the stained glass, enhancing the overall effect. Additionally, an acrylic diffuser can be used to soften the light and prevent the LED lights from becoming visible and distracting.

The placement of the diffuser panel is also important. In a room, direct reflections are often the most crucial waves to capture, so placing the diffuser at the first reflection points can be optimal. Moreover, diffusers can be suspended from ceilings, effectively reducing echoes and reverberation while adding an eye-catching element to the space.

Overall, adding a diffuser panel is a critical step in achieving the desired lighting effect for backlighting stained glass. It helps distribute light evenly, softens the impact of light sources, and ensures that the final visual result is aesthetically pleasing without distracting elements.
