Guangmai Technology is professional in making the 1W Surface Mounted Diode 3030 SMD LED Chip.
SMD LED lamp beads are widely used in daily life. They are usually used in lighting. Many people have no way to judge the positive and negative poles of SMD LED lamp beads. The high-grade LED diode brand GMKj LED will share with you: SMD LED lamp Judgment method and basic knowledge of the positive and negative poles of beads!
SMD LED lamp beads-distribution
SMD LED lamp beads are usually produced in red, green, and blue. According to the different distribution positions of the SMD LED lamp beads, it can be divided into high directivity SMD LED lamp beads, standard SMD LED lamp beads, and scattering SMD LED lamp beads. High directivity is a pointed epoxy package. Or it can be packaged with a metal reflective cavity without adding any scattering agent. It has high directivity and can be used as a local lighting source. The standard type is usually used as an indicator light, and its half-value angle is between 20° and 45°. The scattering type refers to the indicator light with a larger viewing angle, and the half-value angle is before 45°～90° or greater.
SMD LED lamp beads-Features
SMD LED lamp beads are divided into ordinary brightness LED lamp beads according to luminous intensity and working current. The luminous intensity between 10-100mcd is called high-brightness SMD LED lamp beads. The working current of common SMD LED lamp beads is more than ten mA to tens of mA, while the working current of low current lamp beads is below 2mA. SMD LED lamp beads have small size, long service life and low power consumption during use. , High brightness, environmental protection, suitable for mass production, durable and reliable, fast response, energy saving, shockproof, shockproof, high resolution, designable and many other advantages. It is widely used in the current industrial field.
SMD LED lamp beads-color classification
With the development of society, SMD LED lamp beads are used in large quantities, making the types, styles and performance of SMD LED lamp beads continue to increase. According to SMD LED lamp beads, it can be divided into: orange, red, green, yellow-green, and pure green. , Standard green, blue light, white light and other different types. There are also chips with two or three colors inside the SMD LED lamp beads. SMD LED lamp beads can be divided into four types: colorless and transparent, colored and transparent, colored scattering, and colorless scattering according to whether the light from the SMD LED lamp beads is mixed or not mixed with a scattering agent, colored or colorless.
SMD LED lamp beads-positive and negative discrimination
The judgment of the positive and negative poles of the SMD LED lamp bead is particularly important. The brightness of the lamp is determined by the SMD LED lamp bead. The observation method for judging the positive and negative poles of the SMD LED lamp bead: Looking down, one side with a colored line is the negative electrode, on the contrary The other side is the positive pole. For large-sized LED lamp beads, there are some marks near the pole piece pins, such as cutting corners, painting, or different pin sizes. Generally, there are signs. Smaller and shorter pins are negative; small size The 0805 and 0603 packages have a T-shaped or inverted triangle symbol at the bottom. The T-shaped one is the positive pole. The side of the triangle symbol is close to the positive polarity, and the corner close to the negative is the negative pole.
3535 rgbw smd leds are mainly from ceramic and Osram/Sanan chips.
It has 4 chips inside and each chips can be powered with 1 watt 300-350mA.
It is very very small package with reliable performance.
Many clients are using it for the outdoor LED wall washer lights, stage lights and so on.
