How to choose the led light bar?
There are several kinds of LED light strips. When it comes to LED light strips, many people may not be very clear. For those who do interior design, they should be very clear about LED light strips. How to select the LED light strip? When selecting the light strip, we also need to pay attention to the brand. From what I have learned, there are many brands of light strips on the market, but the quality is uneven.

How many kinds of led light bars are there?
1. Backlit led light box light strip:
Advantages: flexible size, flexible spacing, simple installation and convenient maintenance, which can meet the requirements of different light box sizes. There are two kinds of products, waterproof and waterproof.
Disadvantages: It is not convenient for small special-shaped light boxes.
It is applicable to light boxes with a thickness of more than 5cm. The lighting of light boxes with different sizes, different brightness requirements and different application scenarios can be adjusted as required. Its application fields are very wide, such as various advertising light boxes, soft film ceilings, etc.
The backlight led light box light bar is a kind of light box factory used at present.
2. Side led light box light strip:
Advantages: the overall power consumption of the light box is low, the material cost is low, the brightness is moderate, the installation is simple, and 220V direct power supply does not require power.
Disadvantages: It is not suitable for customers with high brightness requirements. Most of the light strips of side LED light boxes are not waterproof, and the requirements for waterproof treatment of light boxes are relatively high.
It is applicable to the light box with a distance of less than 3m, such as the light box in the waiting hall and the mobile phone light box.
How to choose the led light bar?
Chips are now mostly chip packaged, such as 5730283530143528, etc. The technology is relatively mature, the difference is mainly in light efficiency, light attenuation, and color rendering. At present, whether Kerui (too expensive for few people to use) or the chip, or domestic chips such as San'an, or the lamp beads of Samsung Philips, the gap is not very big. It is mainly about the fluorescent powder and packaging technology, as well as the power supply, heat dissipation, and overall coordination of the bulbs. It's a bit like the cask effect.
In terms of the shell, the aluminum shell is a little more expensive than the plastic one, and the heat dissipation is also better; However, the aluminum shell also needs an isolated power supply (a little expensive), otherwise it is not safe enough; The isolated power supply will lose some efficiency; Therefore, most manufacturers in the market currently choose "plastic coated aluminum+non isolated power supply", which has low cost. The bad thing is that they sacrifice heat dissipation, which has some impact on their life.
At present, there are many mid-range LEDs on the market (some international brands are expensive, but they do not show particularly good performance, they are all OEM). It is difficult to find particularly good LEDs. Most of them have a color rendering index of 80. The light always feels awkward. I would like to recommend that we are not satisfied with the LED in the market (there are too few high color rendering LEDs), so we made a LED with a color rendering index of 96. The color temperature is 4500K and 3000K, the strobe free isolated power supply (low PF), 1060 aluminum fin shell, and the luminous efficiency of the lamp bead is 100lm/w.
There are several kinds of LED light strips. Now there are more and more light strips on the market. You must be careful when choosing. How to select the LED light bar? There are certain methods. When you buy, we can also use it personally to see if there is a bad light bar. If there is a bad light bar, you can replace it with the merchant on the spot. When installing, you must pay attention to cutting off the power.
