LED Lamp Beads Common Parameters And Types Explanation
Common parameters of LED lamp beads
Luminous color:
LED lamp beads emit a variety of colors, including red, green, blue, and white, with different wavelengths and brightness parameters for different colors.
Color temperature:
LED lamp beads have the function of adjusting color temperature, with a value range usually between 2500K and 8500K. The lower the color temperature, the warmer the light emitted; the higher the color temperature, the whiter the light emitted.
Brightness:
The brightness of LED lamp beads is usually expressed in lumens (Lm). LED lamp beads of different sizes and specifications have different brightness.
Voltage:
The voltage of LED lamp beads is usually between 1.5V and 4V, depending on the specific model. Usually, a current limiting resistor is required when using 220V mains power.
Lighting angle:
The light emission angle of the LED lamp bead determines whether the light is concentrated. Generally, the smaller the angle, the more concentrated the light emitted by the lamp bead.
Finally, different models and brands of LED lamp beads may also have other parameters.
How many kinds of LED lamp beads are there?
RGB LED lamp beads: The chip emits light in three colors: red, green, and blue. The brightness of different colors can be controlled by an external IC to achieve various color combinations.
SMD LED lamp beads: SMD LED lamp beads are manufactured using a patch process. This product has excellent lighting effects and good crash resistance, while being small in size, low in brightness, and low in power consumption.
COB LED lamp beads: using integrated circuit packaging technology, multiple LED chips are integrated into a small area to form high-brightness lamp beads.
The above are several common types of LED lamp beads. Different types of LED lamp beads are suitable for different application fields. If you want to know more about lamp beads, please consult our specialists.
What are the conventional types of LED lamp beads?
LED lamp beads are a common type of LED product and are widely used in the LED lighting market. Different LED lamp bead specifications have different power, brightness, color, and other characteristics to meet the needs of different situations. Here are some common LED lamp bead specifications.
2835 LED lamp beads
The 2835 lamp bead is a common monochromatic lamp bead with a size of 2.8 mm x 3.5 mm and a power range of 0.2-0.5 watts, emitting red, yellow, blue, green, white and other colors. Due to its small size and good heat dissipation performance, it is widely used in various portable lighting devices and automotive headlights.
3528 LED lamp beads
The 3528 lamp bead has a size of 3.5 mm × 2.8 mm and a power range of 0.06-0.08 watts. It can emit red, yellow, blue, green, white and other colors of light. It is suitable for backlighting, indoor lighting and other fields.
5050 LED lamp beads
5050 lamp beads, with a size of 5.0mm×5.0mm, have a power range of 0.15-0.2 watts and can emit multiple colors with good heat dissipation. They are suitable for outdoor lighting, architectural contour lighting, automotive lamps, indoor lighting, and other fields.
In general, the specifications and models of LED lamp beads have their own application ranges and characteristics, and should be selected according to actual needs when purchasing. With the continuous advancement of LED technology, we believe that in the future, there will be more specifications and models of LED lamp beads.
