LED lamp bead's technical parameters

2. LEDs with strong antistatic ability and static capabilities have long life, so the price is high. LEDs, which are usually anti -static than 700V, can be used for LED lighting 3. LEDs with the same wavelength and wavelength. If the color is consistent, if the color is consistent, the price is high. Manufacturers without LED spacing divisions are difficult to produce pure color products.大功率LED灯珠详细参数及点光源选择技巧白光分暖色（色温2700-4000K），正白（色温5500-6000K），冷白（色温7000K以上）欧洲人比较喜欢暖白红光：波段600-680, Among them, 620,630 is mainly used for stage lights. 690 is close to infrared blue light: band 430-480, of which 460,465 stage lights are used more. Green Light: The band is 500-580, of which 525,530 stage lights are used more. 4. The leakage current LED is a unidirectional conductivity luminous body. If there is a reverse current, it is called LED with a large leakage current with a large life span and a low price. 5. LEDs with different use of light emitting angle are different. The special lighting angle, the price is high. 6. The key to different quality of life is life span, and life is determined by light. Light failure, long life, long life, high price. 7. The luminous body of the LED chip LED is a chip, with different chips, the price is very different. Chip in Japan and the United States is more expensive. The price of LED chips between Taiwan factories and Chinese manufacturers is lower than Japan and the United States. 8. The size of the chip size chip is represented by the side length. The size of the chip is generally: 38-45MΩ. The quality of the large chip LED is better than that of small chips. Price is proportional to the size of the chip. 9. The colloidal colloid with ordinary colloids is generally epoxy resin. The price of LEDs with anti -ultraviolet and fireproof agent is more expensive. High -quality outdoor LED lighting should resist ultraviolet rays and fire prevention. Detailed parameter and point light source selection techniques of high-power LED lamp beads 10. The color rendering value is white: 60-6, warm white: 50-60. Because the packaging fluorescent powder used by different companies is different, the color rendering value is different. From the perspective of health, the price of products with non -toxic materials should be high, especially indoor LED lighting. Don't be greedy for cheap LED lighting. At present, only a few LED manufacturers are produced by non -toxic materials to distinguish methods. You can use the nose directly, and the product with odor is much lower than the odor without odor. Toxins such as lead, mercury, cadmium, etc. need to analyze professionals. From the perspective of applicable environmental safety, there is a reliable dustproof and moisture and anti -anti -design, material fire prevention, ultraviolet rays, and low -temperature cracking LED products. The technical parameters of LED mainly include luminous strength, color, wavelength, color temperature, etc. Below we give a brief introduction to these parameters. The light intensity (IV) light strength is defined as the optical flux emitted by the three -dimensional corner of the unit, and the unit is candlelight (CD). Generally speaking, the light source radiates its light flux in different directions in different directions, and the visible light radiation intensity released in the three -dimensional angle of the unit in a specific direction is called the light intensity. Chromaticity's perception of human eyes is an intricate process. In order to quantify the description of color, the International Lighting Association (CIE) according to the visual experiments of the standard observer, the radiation energy in different wavelengths of the wavelength is based on the visual experiments of the standard observer. Calculating the visual sense of visual and calculating the color matching function of the three primary colors of red, green, and blue. After mathematical conversion, the so -called CIE1931COLOLORMATCHINCTION (x ((), y ((),), z (())函数，后续发展出数种色彩度量定义，使人们得以对色彩加以描述运用。根据CIE1931配色函数，将人眼对可见光的刺激值以XYZ表示，经下列公式换算得到x,y值，即CIE1931( X, y) color coordinates, through this unified standard, the description of color can be quantified and controlled. X, Y: CIE1931 chromaticity coordinates The color gamut constructed is non -uniform, making the color difference difficult to quantify, so in 1976, CIE converted the CIE1931 chromaticity coordinates to make the color gamut formed by the color space close to uniformity, so that the color difference can be quantified, and the color difference can be quantified. That is, CIE1976UCS (UniformchromativeScale) color coordinates, which are represented by (u ', v'). The calculation formula is shown below: the main wavelength (λD) is also one of the methods to express the color. After x, y), marked it on the CIE chroma coordinates (as shown below), and connect E -light source chroma (color coordinates (x, y) \u003d (0.333,0.333)) Line, the wavelength value of this extension line with the spectral trajectory (horseshoe shape) is called the main wavelength of the measuring part. However, it should be noted that the same main wavelength will represent multiple different chroma points under this label method, It is more meaningful to be used to be adjacent to the spectral trajectory of the color point to be tested, while the white LED cannot describe its color characteristics in this way. Purity is the assistant representation when the color is described by the main wavelength, and the percentage is percentage. The calculation is defined as a percentage of the colorful coordinates of the color coordinates and the color coordinate of the E -light source to the e -light source to the main wave of the test parts to the main wave of the test parts (SpectralLocus) color coordinate distance. The closer the color coordinates of the main wavelength, the higher the spectrum of the main wavelength. When a standard black body (Blackbodyradiator) radiation energy distribution is the same, its light source chroma is the same as the color of this black body radiation. At this time (ColorTemperator) The color of the black body radiation at each temperature may be marked on the color map, which is called the PlanckianLocus. The higher the temperature of the standard black body, the more the radiated light has blue stimulation to the human eye, and the red stimulus component is relatively reduced. However, in terms of actual measurement, no light source has the same radiation energy distribution as the black body. In other words, the color of the light source usually does not fall on the Plack trajectory. Therefore, calculate the closest coordinate point on Platin's trajectory of the color coordinates of the light source. The black body temperature of this point is defined as the correlation -related color temperature (CCT) of the light source (CCT). Seek the diagram and describe the color difference △ UV. It should be noted that this means of the formation of the square in the light source is adjacent to the Planck trajectory. For the LED amount, it is only suitable for the color description of the white light LED.
