LED lighting is a terrific way of lighting signs in an effective and affordable way. When done right, it looks terrific.
However, the biggest problem with LED lighting is it has the propensity to generate hot spots in-between the sign. Hot spots are basically excessive lighting in a particular part of the sign which creates a shadow on the areas with lower lighting.
This happens when LED lights are put very close to the sign’s face or aren’t properly distributed all over the sign. In order to make sure the lighting remains consistent throughout, proper LED placement is critical.
Experimentation is required which places the LED’s in various areas in order to find the correct placement in each of the signs. All of the signs will need more LEDs in some areas and fewer in others. LED lighting remains custom for each of the signs based on shape, size, and the amount of light that is required.
Emphasize Lettering using LED Lights
When used properly, LED lights can help create some sterling designs and make letters pop. But there are many problems that incorrect installation of these lights could cause as well. For example, if the lights face straight forward, they could end up creating hot spots as well as uneven lighting. Instead, they need to be facing backwards and evenly reflecting the light outward from the back of the sign instead of shining directly towards the viewers.
This will help in creating the brightness required by the sign without creating uneven lighting or overdoing it. The most paramount aspect in any LED lighting project is the precise placement of the lights.
LED can also prove to be terrifically useful when it comes to lighting signs with large faces. But it isn’t as simple as sticking lights just anywhere and then putting a face over it. If you do this, you are going to face the same problem of uneven lighting and hot spots over the sign’s face.
Uneven lighting will also affect the clarity and visibility of a sign and looks very bad.
It is crucial that each of the LED lights are placed inside the sign and distributed evenly at the correct distance. Remember that if the lights get too close to the face, they are going to reflect the light unevenly too. It is also vital to pay attention to anything inside the sign which might cause shadows.
Experimenting with various positions until you are able to produce an even lighting from the placement is necessary almost every single time.
Now, let’s look at a couple of the benefits of using LED lighting on signs:
- Long life: A quality LED will last for as much as 100,000 hours which is six years longer than regular neon or fluorescent bulbs. They don’t just outlast them but since they do not have any gases in them, they maintain a constant level of brightness too. So they are clearly advantageous.
- Appearance: It is a constant battle to keep fluorescent or neon signs fully lit and with constant brightness. Some of the lights are going to invariably need replacing or get dimmer than the others. This can create a sincere problem since dim lit signs can send a bad message about a business and make customers believe you aren’t conscientious. With LED’s you will not have this problem since they last very long and are made using efficient technology which keeps them illuminated in a far more uniform way than traditional lights.
Keeping the above tips in mind is essential if you want to have hot spot free, well-lit signs.

I know what you mean when you describe hot spots in illuminated signs. It makes poorly lit LED signs hard to read at night. Placing the LEDs so they face backwards and that the light is reflected to the surface is such a smart idea. I can see how that would easily illuminate the hot spots.
