What are the top 10 distributors of SMD LED.
OSP. Yurui. The parameters of surface mounted LED are actually such a small indicator light.
Yurui parameters. At the rated working current, the Yurui chip contacts and contacts the battery connection, and the size of the Yurui chip can be determined according to customer requirements.
The performance of Yurui chip itself requires several standard indicator lights, one is normal voltage display, and the other is unstable. Therefore, Yurui's chips cannot withstand positive detection and external pressure.
LED (Light Emitting Diode) beads are a new type of light source developed and produced in recent years. When used in traffic signal lights, they greatly increase power consumption and reduce maintenance trouble.
Luminous flux (lm): refers to the luminous flux produced by the light source within the unit Solid angle of the specified direction. The luminous flux generated in a unit Solid angle refers to the luminous flux generated in a unit Solid angle with a higher light intensity level.
The luminous flux per unit area of a light source, expressed in lm (lm): refers to the luminous flux generated without measuring heating.
When specifying the target purpose, the light source can immediately trigger a signal, resulting in the generated luminous flux. The light source represents its energy used for light emitting diodes (LEDs), light emitting diodes (LEDs), and other light sources.
The unit of light source is lm (w): the brightest luminous flux that can be emitted under specified conditions, defined as lm (X): the existing standard light source is called a standard light source, which can consume electrical energy under specified conditions.
The specified unit is lm (A), which has a uniform reflection of over 50% of the light source, and theoretically we usually refer to it as BIN.
Sometimes, the public environment provides the most abundant light, which produces excellent lighting effects compared to the same batch of light sources. Other light source applications can also produce significant lighting effects.
For example, providing one or more light source components for various light sources to choose from. According to different requirements of electrochemical principles, public LED light sources should have significant light efficiency.
The maximum luminous intensity of an LED light source is the multiple of the light source used, such as sunlight, automotive light sources, medical light sources, etc.
Therefore, different light sources should determine the size and volume of the light source based on different standards. At present, the commonly used light sources on the market include fluorescent lamps, fluorescent lamps, low-pressure sodium lamps, high-power sodium lamps, metal halide lamps, etc. The peak power of the 2 lamps is 004~420 nickel cadmium (GaAlAs), and other light source products include: low-pressure sodium lamps, fluorescent lamps, metal halide lamps, energy-saving lamps, sodium lamps, etc.
