What color is the lamp

In order to decorate homes, there are often many accessories with decoration effects that may have unexpected and good results. For example, talk about lights! What is a light strip? The light strip is a type of light fixture that is connected to a power source by soldering the LED light to a copper wire or a strip-like circuit board through a special process. Because the shape of the light strips is changeable and the colors are varied, people choose the light strips to make a choice of phobias. What kind of colors do the lights have? Do not worry, Xiao Bian take you to see what color of the light with a good look!

Light strips

The lamp strip refers to the LED lamp is welded to a copper wire or a ribbon-shaped flexible circuit board by a special processing technology, and then connected to the power supply to emit light, and its shape is named as a light strip when it is lighted.

Lamp features

1, soft, can curl like a wire;

2, can cut and delay;

3, bulb and circuit are completely covered in flexible plastic, insulation, waterproof performance, use safety;

4, strong weather resistance, not easy to break, long service life;

5, easy to create graphics, text and other modeling.

What color is the lamp

With the choice of lamp color, it should be said that everyone has their own hobby, generally speaking, the ceiling is usually white and other light colors.

Study room, children's room should use yellow, color. A room with a hue is good.

Light belt quality identification skills

1, see solder joints.

The LED strips produced by the manufacturer of the regular LED strips are produced using the SMT chip process using solder paste and reflow soldering processes. Therefore, the solder joint on the LED lamp strip is relatively smooth and the amount of solder is not large, and the solder joint is arc-shaped and extends from the FPC pad to the LED electrode. On the other hand, the amount of solder in the solder joints of the cottage version of the LED strip is not uniform, and it is often surrounded by a dot that covers the solder fillet. At the same time, tin spikes of different degrees appear. This is a typical phenomenon of manual soldering.

2, see FPC quality.

FPC is divided into copper and rolled copper. The copper foil of the copper is protruding. If you look closely, it can be seen from the joint between the pad and the FPC. The rolled copper is closely integrated with the FPC, and can be bent freely without pad dropout. If the copper plate is bent too much, the pad will fall off. If the temperature is too high during repair, the pad will fall off.

3, look at the cleanliness of the LED light strip surface.

If the LED light strips produced by the SMT process are used, the surface cleanliness is very good and no impurities and stains are visible. However, if the cottage version of the LED light strip produced by the hand-welding process is used, no matter how the surface is cleaned, there will be traces of stains and cleaning residues, and there will be residual flux and tin residue on the surface of the FPC.

4, see the packaging.

The regular LED strips will be packaged in anti-static roll trays, typically 5 meters in rolls or 10 meters in rolls, and then sealed with anti-static moisture-proof bags. The cottage version of the LED strip will use recycled reel trays because of cost savings, and then there is no anti-static moisture-proof packaging bag. Look carefully at the reel tray to see traces and scratches left on the exterior when the label is removed.

5, see the label.

The regular LED lights will have a printed label on top of the bag and reel, not a printed label. The cottage version of the label is printed, while the specifications and parameters are not uniform.

6, see attachments.

The regular LED strips will be accompanied by instructions and lamp strips in the box, and will also be equipped with LED strip connectors or decks, while the cottage version of the LED strips will not contain these accessories because After all, some manufacturers can still save the province.

Lamps with purchase and use precautions

1, led lights with the components, there are light beads - guide plate - wire - glue - resistance - wire - accessories. Pay attention to the selection of regular big brands when purchasing, so that the quality can be well protected. (The width of the lamp guide should be more than 6mm when it is selected. Less than 6mm of the guide will lead to the lamp with insufficient board width. Produce a lot of heat, there is a serious safety hazard, so pay attention to the width of the guide plate when buying.)

2, when the lights with a cut to pay attention, there is a special scissors mouth, the light belt is generally one meter a circuit, the whole meter place will generally have a 1 cm blank is a special scissors need to cut from the scissors mouth .

3, the light belt is equipped with accessories, accessories generally have cross current plug (is the transformer lamp must use) line card (fixed lamp with a plastic clip) tail plug (protection lamp with a plastic tail of the sets) to buy a lamp with When you want to ask business, oh, or leaking accessories will not work.
