LED filament lights gradually rose in the first half of 2014

In 2014, LED filament products became a highlight in both the Frankfurt exhibition and the Guangya exhibition. The perfect combination of traditional incandescent lamp technology, the realization of 360 lighting, and the preference of Europeans and Americans for incandescent lamps have made LED filament lamps attract more attention. The manufacture of LED filaments is a packaging method in which a plurality of low-power LED chips are packaged in series on a substrate, which are connected in series by a gold wire, and the phosphor coating is wrapped. The filament substrate is mostly sapphire, and a few are glass or metal substrates. . If the LED filament is made with a flip chip, its heat dissipation and light efficiency will be better. Therefore, the current flip chip COB package is the best method for LED filament fabrication. With the in-depth research and complete improvement of LED filament manufacturing technology, LED filament application technology, glass bubble encapsulation and non-strobo power technology, many incandescent lamps have successfully transformed and upgraded into LED lighting field. At present, there are more than dozens of manufacturers involved in the field of LED filament lamps in China. These manufacturers are mainly divided into three categories, one is traditional lighting and incandescent lamp manufacturing enterprises, including Buddha Photo, Yaming, NVC, etc. LED lighting products manufacturing enterprises, including Dongshan Lighting, Yapu Er, Yinjing Optoelectronics, etc.; and one type of LED packaging companies, including Zhongzhou, Hongli, Hangke, Baishi and so on. Some of the company's products have been publicly available, but not much to achieve mass production. Some of the LED filament lamp products and photoelectric parameters sold in Taobao are shown in Table 1. The average luminous efficiency has exceeded 100Lm/W, the light color is warm white, white, cool white, and the lamp socket interface is E14 or E27, so Direct replacement of incandescent lamps. CSAResearch believes that because LED filament lamps are currently the closest LED lighting products to incandescent lamps, combined with features such as full-angle illumination, no lens, and incandescent lamp production lines, if the heat dissipation and cost issues are solved, today's nostalgic retro trend There will be great market prospects in the replacement market below.

Matt Vinyl Wrap

Matte vinyl wrap is a type of vinyl material that has a non-glossy, flat finish. It is commonly used to wrap vehicles, such as cars, motorcycles, and boats, to change their appearance and protect the original paintwork. Matte vinyl wrap gives a sleek, modern look to the vehicle and can be customized with various colors and designs. It is a popular alternative to traditional glossy vinyl wraps and offers a unique aesthetic appeal.

Installing matte vinyl wrap can be a bit tricky, but with the right tools and techniques, you can achieve a professional-looking finish. Here's a step-by-step guide on how to install matte vinyl wrap:

1. Gather your materials: You will need matte vinyl wrap, a squeegee, a heat gun or hairdryer, a sharp utility knife, rubbing alcohol or a vinyl wrap cleaner, and a microfiber cloth.

2. Prepare the surface: Clean the surface thoroughly with rubbing alcohol or a vinyl wrap cleaner to remove any dirt, grease, or wax. Use a microfiber cloth to ensure a clean and dry surface.

3. Measure and cut the vinyl wrap: Measure the area you want to wrap and cut the vinyl wrap slightly larger than the area to allow for trimming. Use a sharp utility knife and a straight edge to make clean and precise cuts.

4. Peel off the backing: Carefully peel off a small portion of the backing from the vinyl wrap, exposing the adhesive side. Be careful not to touch the adhesive with your fingers to prevent any oils or dirt from transferring onto the wrap.

5. Apply the vinyl wrap: Align the exposed adhesive side of the vinyl wrap with the edge of the surface you are wrapping. Slowly press down the vinyl wrap onto the surface, using a squeegee to smooth out any air bubbles or wrinkles. Work from one edge to the other, applying even pressure.

6. Use heat to stretch and conform the wrap: Use a heat gun or hairdryer to warm up the vinyl wrap as you go. This will make the wrap more pliable and easier to stretch and conform to the contours of the surface. Be careful not to overheat the vinyl, as it can cause damage.

7. Trim the excess vinyl: Once the vinyl wrap is applied, use a sharp utility knife to trim off the excess vinyl. Be careful not to cut into the surface underneath. Use the squeegee to press down and smooth out the edges.

8. Heat and reapply if necessary: If you encounter any air bubbles or wrinkles, use the heat gun or hairdryer to warm up the vinyl wrap and reapply it, smoothing out any imperfections.

9. Final touches: Once the vinyl wrap is applied and trimmed, use the heat gun or hairdryer to heat up the edges and corners, and use the squeegee to press them down firmly for a secure and clean finish.

10. Allow time to cure: Give the vinyl wrap some time to cure and adhere properly. Avoid washing or exposing the wrap to extreme temperatures for at least 24-48 hours.

Remember, practice makes perfect, so don't be discouraged if your first attempt is not perfect. Take your time, be patient, and follow these steps carefully to achieve a professional-looking matte vinyl wrap installation.
