Viewing brightness: Different LED beads have different prices. Light emitting diodes must meet the laser first level standard.
Anti static performance: LED lamp beads with strong anti static ability have a long lifespan and are therefore expensive. Generally, anti-static LED beads can be used with LED beads above 700V.
Check if the wavelength consistency meets the standard: LED beads with consistent wavelengths have consistent colors. If color consistency is required, the price is high. It is difficult for manufacturers to produce color separators without LED lamp beads to achieve pure color.
Detection of leakage or not: The leakage current LED bead is a unidirectional conductive light emitting body. If there is reverse current, it is called leakage or leakage current LED bead, with short lifespan and low price.
Observation of luminous angle: LED beads with different purposes have different luminous angles. Unique luminous angle and expensive price. If the scattering angle is complete, the price is higher.
Evaluation of lifespan: The key to different quality of life is lifespan, while light decay depends on light decay. Low light attenuation, long lifespan, and high price.
Distinguishing chip level: Chip light-emitting diodes are chips, and prices vary greatly depending on the chip. In Japan and the United States, chips are relatively expensive, while in general, the prices of chips in Taiwan and China are lower than those in Japan and the United States.
Difference in chip size: The chip size is represented by the side length, and the quality of LED lamp beads on large chips is better than that on small chips. The price is proportional to the size of the chip.
Whether the safety meets the standard: The gel of ordinary LED light beads is generally epoxy resin, and LED light beads added with UV and fireproof agents are relatively expensive. High quality outdoor LED light beads should be UV and fireproof. In terms of reliability design, LED lighting includes factors such as electrical safety, fire prevention, applicable environment, mechanical safety, health and safety, usage safety, usage safety, and usage safety. In terms of electrical safety, it should comply with relevant international and national standards.
