Hey there, friends! As a supplier of wall lamp plastic housing, I've gotten a ton of questions lately about whether the plastic housing has any impact on the light output of wall lamps. Today, I'm gonna dig deep into this topic and share some insights based on my experience in the industry.
Let's start by understanding why wall lamp plastic housing is even used in the first place. There are a bunch of reasons for that. First off, plastic is lightweight, which makes it easy to install and transport these wall lamps. You don't have to worry about heavy, cumbersome materials. Secondly, it's cost - effective. Producing wall lamp housings with plastic can significantly bring down the overall cost of the product, making it more accessible to a wider range of customers. Plus, plastic is highly customizable. We can mold it into all sorts of shapes and sizes, creating unique and aesthetically pleasing designs for wall lamps.
Now, onto the main question: does wall lamp plastic housing affect the light output? The answer is yes, and there are several ways it can do so.
1. Light Transmission
One of the most obvious factors is the light - transmitting properties of the plastic. Different types of plastic have different levels of transparency. Clear plastic allows almost all the light to pass through. So, if you use clear plastic for the wall lamp housing, the light output won't be significantly obstructed. The light can shine through just as brightly as it would without the housing.
On the other hand, frosted or opaque plastic is used in some cases for aesthetic reasons. Frosted plastic diffuses the light, creating a softer, more even glow. While it doesn't totally block the light, it does reduce the overall brightness that reaches the outside. Opaque plastic, however, blocks most of the light. It's often used to hide the light source or for decorative purposes, but you'll definitely notice a big drop in the amount of light that's visible.
Let me give you an example. Say you have a LED light source in a wall lamp. With a clear plastic housing, the light can spread out far and wide, illuminating a large area. But if you swap that for a frosted or opaque plastic housing, the area that gets well - lit will be smaller, and the light will seem dimmer.
2. Color Absorption
Plastic can also absorb certain colors of light. For example, if the plastic has a slight tint, it will absorb light in the wavelengths corresponding to the complementary color of the tint. A yellow - tinted plastic housing will absorb some of the blue light, which can change the color temperature of the light that comes out.
This isn't always a bad thing, though. Sometimes, a change in color temperature can create a more cozy or inviting atmosphere. But if you're looking for a specific color of light, like pure white light for a workspace, the color absorption by the plastic housing can be a problem.
3. Reflection and Refraction
The internal surface of the plastic housing can cause reflection and refraction of light. If the plastic has a smooth surface, it can reflect light in an organized way, which might direct the light in a specific direction. This can be useful for creating a focused beam of light.
However, if the surface is rough or has irregularities, the light will be scattered in all directions. While this can create a more diffused light, it can also reduce the overall efficiency of the light output. Some of the light energy is wasted as it bounces around inside the housing instead of being directed outwards.
4. Heat and Light Output
Plastic can be affected by heat. As the LED light source in the wall lamp heats up during operation, the plastic housing can absorb some of that heat. If the plastic starts to deform due to heat, it can change the way it interacts with the light. For example, if the plastic warps, it might block more of the light or change the direction of the light rays.
Moreover, excessive heat can also reduce the lifespan of the LED bulb itself. So, a good wall lamp plastic housing should be able to dissipate heat effectively to maintain a stable light output.
At our company, we've taken all these factors into consideration when designing our wall lamp plastic housings. We have a wide range of products to meet different needs. For instance, if you're looking for a wall lamp that provides a bright, focused light, you might be interested in our LED Wall Lamp In Curve With PIR. This lamp has a clear plastic housing that allows for maximum light transmission and is equipped with a PIR sensor for added convenience.
If you need a wall lamp for outdoor use, our Waterproof Outdoor Wall Light is a great option. The plastic housing is made of high - quality, waterproof material that can withstand various weather conditions while still providing a decent light output.
And for those of you who have a garden porch and want a stylish yet functional light, check out our Plastic Garden Porch Light with PIR Sensor. The frosted plastic housing creates a soft, inviting glow that's perfect for a relaxing outdoor space.
