At present, people's lives can not be separated from the existence of lamps and lanterns. With the development of the times, indoor lamps and lanterns have changed from the original bulbs to the current LED lamps. They not only have better brightness, but also play a certain eye protection mode, and also have great advantages in power saving. For example, Oval LED,oval led lights, 546 346mm Queendom led ,Oval LED can be easily used in any lamp to play the role of light source. Today, let's lea
In life, we often see some outdoor advertisements or signal indicators showing a variety of colors, so that people can better identify them. In fact, these are the effects of LEDs. Decorating some scenes with LEDs can not only play the role of lighting, but also beautify the scene. It can be said that the effect is quite large. How to buy rectangular LEDs? Is the price expensive?
Only when we know how to judge the quality of a product, can we make more accurate choices when we buy it. Therefore, when we buy some items, we will first have a simple understanding of them. For example, LED lamps can be more clearly selected in the process of purchase after we accurately judge the quality. So how to correctly distinguish the quality of round leds?
Lamps are an important part of our life, and the traditional existence of lamps is only for lighting, but with the development of the times, people have higher and higher requirements for lamps, not only for lighting, but also for certain aesthetics, so as to meet people's needs for decoration. In addition, many people will buy a variety of lamps and lanterns to decorate the scene, and LED lamps have become the choice target of many people, What are the selection methods of through hole LED lamp
High power lamp beads are essentially the same as ordinary LED lamp beads, except that the power is larger than ordinary LEDs. Generally speaking, if the rated current exceeds 100mA, it can be called high-power lamp beads. High power lamp beads can be 1W, 3W, 10W, or even 100W, 200W, and 1000W. They are loved by many customers because of their strong light efficiency, fast response speed, good color change effect, and high efficiency and energy conservation.
More and more purple light beads have come into people's vision, such as money validators, nail polish lamps and disinfection lamps. We can easily distinguish purple lights, but what does purple light beads mean? What are its uses?
At present, there are many kinds of LED lamps on the market, which makes people dizzy. Many people are very confused when choosing IR LED, and do not know what characteristics and advantages IR LED have. Let's take you to know today.
LED is a kind of light-emitting diode that can convert electrical energy into visible light. The medium and high-power LED is a light-emitting diode that can convert electrical energy into visible light and has a large rated working power.
I believe there are many LED products in many families, such as Through hole LED lights, LED displays, led bedside lamps, etc. we get along with LED products day and night, but do you know what in-line LED is?
LED diode bracket
1.1 The role of the bracket: conduction and support;
1.2 The composition of the stent: the stent is formed by electroplating the stent material, which is composed of five layers of material, copper, nickel, copper and silver from the inside to the outside;
LED light-emitting diodes have a great effect, and it is known that light-emitting diodes are widely used. In the field of car lights, lighting industry, wall washers, beauty instruments and other fields have played a great role. But what are the installation tips for such a small light-emitting diode.
Queendom LED light-emitting diodes have a great effect, and it is known that light-emitting diodes are widely used. In the field of car lights, lighting industry, wall washers, beauty instrument
What is a DIP LED?I believe that there are many LED products in many families, such as in-line LED lights, LED displays, LED bedside lamps, etc. We get along with LED products every day, but do you know what in-line LEDs are? Below I will take you to find out.
What are LED specifications?According to the light-emitting color of the light-emitting tube, it can be divided into red, orange, green (subdivided into yellow-green, standard green and pure green), blue light, etc. In addition, some LED light-emitting diodes contain chips of two or three colors. According to whether the light-emitting diode is doped with or not doped with a scattering agent, colored or colorless, the above-mentioned light-emitting diodes of various colors can also be divided in
led manufacturing process flow chart?Queendom Technology led lamp bead production process crystal bonding (crystal bonding machine) - into the baking (oven) - welding wire (wire bonding machine, push-pull test instrument) - spot fluorescent glue (glue dispenser) - glue filling (mixer, vacuum machine, glue filling machine) - front cutting (front cutting machine) - testing (exhaust testing machine) - back cutting (rear cutting machine) - spectroscopic (spectroscope), the production process and the
