led lighting - what are beam angles?

by:DGT Lighting     2020-06-29
One thing you often hear about LED bulbs is that they have a narrower beam angle than the old stylish incandescent lamp, or even a narrower beam angle than the new CFLs.
What does that mean, is this a problem?
The beam angle is the angle from which the light is emitted from the bulb.
So for the spotlight, a small angle of 20 degrees is appropriate to focus the light on a small area.
If you want more general lighting to spread the light throughout the room, it\'s better to have a bigger angle of 90 degrees.
In most domestic lighting cases, the beam angle is 30-
45 degrees is enough to illuminate the room comfortably.
The idea that Led has a narrow beam angle stems from the old technical led, which is indeed designed for focused light in a narrow area.
This is no longer a fact today.
Now, the new technology means that LED bulbs can be provided at various beam angles from narrow spotlights to wider general lighting.
Some LEDs can be purchased in the beam angle range of 15, 30, 40, 45, 60, 90 to 120 degrees.
This means that there are a lot of choices in the market, and sometimes too many choices, buyers will be confused.
You can no longer grab a light bulb from the supermarket shelves.
Have a decision to do!
When choosing LED lighting for your home, the most important thing is to determine what is needed for each area.
Rooms illuminated by a single ceiling light definitely need the maximum beam angle, while rooms with several downlights placed in different areas of the room can use an average of 35-
40 beam angles as the lights will cover different areas of the room and overlap with each other.
You need an LED bulb that is different from the ceiling light, otherwise you may find that you throw the light directly back to the ceiling instead of illuminating your desk or reading material!
When you are just starting to use LED lighting, it makes sense to consult an expert in the field who understands all the different options and can advise on the best lighting solution as per your needs.
Led was a considerable investment at the time of initial purchase, although they made several times as much money in terms of long life and energy saving, so you want to start right.
Look for a lighting expert in your area that stores a wide range of high-quality LED lighting.
They should be happy to take the time to advise on your request.
