In the field of lighting, the performance and quality of LED beads, as the core component of light sources, directly affect the effectiveness of lighting products. Laser bead and laser bead, as two common high-tech bead products, are often mentioned in practical applications. This article will provide a detailed introductionLaser beadThe difference between laser beads and laser bulbs helps readers better understand the differences between the two, in order to make more informed choices in lighting engineering.

1、 Working principle

1. Laser bead: Laser is the abbreviation for "stimulated emission amplification of light", and laser bead is a type of bead that uses laser (radium) to excite a specific medium and produce light amplification effect. The principle of its operation is to use radium rays of a specific wavelength as an excitation source to excite atoms or molecules in a specific medium, causing them to transition to an excited state, thereby generating light radiation with a longer wavelength than the excitation source.

2. Laser bead: Laser is the abbreviation for "light formed by stimulated emission amplification", and laser bead is an optical device formed by amplifying the stimulated emission of atoms or molecules at specific energy levels. Its working principle is to use light radiation of a specific wavelength as an excitation source, causing atoms or molecules to transition from a low energy level to a high energy level, and then radiating photons of the same frequency when returning from the high energy level to the low energy level, forming a beam of light.

2、 Performance characteristics

1. Laser beads: Due to the use of laser as the excitation source, laser beads have the characteristics of high brightness, good monochromaticity, and strong directionality. In addition, the lifespan of laser beads is generally longer, reaching tens of thousands of hours or more.

2. Laser beads: Laser beads have the characteristics of high brightness, high purity, and high directionality, and their brightness is usually several times or even tens of times higher than ordinary LED beads. In addition, the lifespan of laser beads is also very long, reaching tens of thousands of hours or more.

3、 Application Fields

1. Laser beads: Due to their good monochromaticity and stability, laser beads are commonly used in fields that require high precision and reliability, such as scientific research, medical, military, etc. In addition, laser beads can also be used to make various decorations and directional signs.

2. Laser beads: Laser beads have the characteristics of high brightness, high directionality, and high purity, so they are widely used in fields such as long-distance communication, measurement, and indication. In addition, laser beads can also be used to produce high-precision beam and light field distribution measurement instruments.

4、 Comparison of advantages and disadvantages

1. Advantages of laser beads: good monochromaticity, high stability, high brightness, long lifespan, etc; Disadvantages: High manufacturing cost, requiring specific driver circuits and heat dissipation systems.

2. Advantages of laser beads: high brightness, high purity, high directionality, long lifespan, etc; Disadvantages: The manufacturing cost is high, requiring specific driving circuits and heat dissipation systems, and attention should be paid to preventing beam scattering and reflection during use.
