1. Look at the solder joints. The LED strips produced by regular LED strip manufacturers are produced by SMT patch technology, using solder paste and reflow soldering. Therefore, the solder joints on the LED light strip are relatively smooth and the amount of solder is not too much. The solder joints extend from the FPC…
1. The packaging protection of the LED flexible light strip is not perfect, causing the lamp bead to be damaged by impact during transportation. 2. The welding point of the LED flexible light strip has a phenomenon of virtual welding, and the vibration during transportation causes the welding point to fall off and the light…
1) Light distribution technology expands the LED point light source into a surface light source, enlarges the light-emitting surface, eliminates glare, sublimates visual effects, and eliminates visual fatigue; 2) Integrated design of lens and lampshade. The lens has the functions of concentrating and protecting at the same time, avoiding the repeated waste of light and…
1. The life span is different, and the key to quality is life span. Life is determined by light decay. Low light decay, long life, and high price. 2. Chip The luminous body of the LED is a chip, and the price of different chips varies greatly. Chips in Japan and the United States are…
LED bulbs have a long lifespan, and almost no need to be replaced after installation. People may forget what it is to replace bulbs in the future. In addition to being durable, this light bulb also has great potential for energy saving. According to calculations, if half of the light bulbs in the United States…
Light-emitting diode bulbs are fundamentally different from traditional incandescent lamps in terms of structure and light-emitting principles. Diode is a common component in electronic circuit, it is made of semiconductor PN junction, plus electrode lead and tube case. A diode has two electrodes with a PN junction, so it is called a diode. The diode…
Light color is the basic element of visual aesthetics and an important means to beautify the room. The selection of the light source directly affects the artistic effect of the light. LEDs show unparalleled advantages in the art of light color display lamps; color LED products have covered the entire visible spectrum, and have good…
Although the incandescent lamps and halogen tungsten lamps for general lighting are cheap, they have low luminous efficiency (the thermal effect of the lamp consumes nothing power), short lifespan and heavy maintenance workload. However, if white light LEDs are used for lighting, not only the luminous efficiency is high, but also the lifespan Long (more…
Process structure of white LED and white light source. For general lighting, in terms of process structure, white light LEDs are usually formed by two methods. The first is to use “blue technology” and phosphors to form white light; the second is a variety of monochromatic light mixing methods. Both of these methods have successfully…
According to the characteristics of the light emitting surface of the luminous tube According to the characteristics of the light-emitting surface of the luminous tube, it can be divided into round lamps, square lamps, rectangular, surface luminous tubes, lateral tubes, and microtubes for surface mounting. Round lights are divided into φ2mm, φ4.4mm, φ5mm, φ8mm, φ10mm…
