Hello everyone, I am a dream. Today, let ’s introduce the problem of detailed explanation of the 500LED lamp bead LED lamp bead parameter. Here are a dream to summarize this issue and related issues. Let’ s take a look. Catalog of the article: 1. What are the parameters of the LED lamp beads 2. The parameters of LED lamp beads explanation 3. What brand of lamp beads can reach 500 lumens and 4, 500 watts of LED heat How many areas of photos What are the parameters of LED lamp beads? Lantern cup: Generally brightness is 60-70lm; Bubble Lights: Generally brightness is 80-90LM. , Voltage, several strings. 1W red light, the brightness is generally 30-40lm; 1W green light, the brightness is generally 60-80lm; 1W yellow light, the brightness is generally 30-50lm; 1W blue light, the brightness is generally 20-30lm.led lens: one lens is generally used for one lens. PMMA, PC, optical glass, silicone (soft silicone, hard silicone) and other materials. The larger the angle, the higher the light efficiency. With a small angle LED lens, the light must be shot far. 2. LEDs with strong anti -static capabilities with resistance to static capacity, 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. The color is consistent. If the color is required, the price is high. Manufacturers without LED spacing divisions are difficult to produce pure color products.大功率LED燈珠詳細(xì)參數(shù)及點(diǎn)光源選擇技巧白光分暖色（色溫2700-4000K），正白（色溫5500-6000K），冷白（色溫7000K以上）歐洲人比較喜歡暖白紅光：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 (())函數(shù)，后續(xù)發(fā)展出數(shù)種色彩度量定義，使人們得以對(duì)色彩加以描述運(yùn)用。根據(jù)CIE1931配色函數(shù)，將人眼對(duì)可見(jiàn)光的刺激值以XYZ表示，經(jīng)下列公式換算得到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.
LED lamp bead parameter description 1, brightness
LED lamp beads have different brightness and different prices.
Light bead: Generally the brightness is 60-70lm bubble light: Generally brightness is 80-90lm. 1W red light, the brightness is generally 30-40lm1W green light, the brightness is generally 60-80lm1W yellow light, the brightness is generally 30-50lm1W blue light, and the brightness is generally 20-30lm. Note: The 1W brightness is 60-110LM3W brightness up to 240lm5W-300W is an integrated chip, which is packaged with a string/parallel.
LED lens: A lens is generally used in PMMA, PC, optical glass, silicone (soft silicone, hard silicone) and other materials. The larger the angle, the higher the light efficiency. With a small angle LED lens, the light must be shot far. 2, the wavelength The wavelength is consistent and the color is consistent. The price is high.
white light is divided into warm color (color temperature 2700-4000K), white (color temperature 5500-6000K), cold white (color temperature above 7000K) Europeans prefer warm white.
Red Light: The band 600-680, of which 620, 630 are mainly used for stage lights, 690 is close to infrared.
Blu-ray: Band 430-480, of which 460,465 stage lights are used more.
green light: band 500-580, of which 525, 530 stage lights are used more. 3, light emitting angle LED with different uses of different luminous angles. The special lighting angle, the price is high.
4. Anti -electrostatic capabilities LED lamp beads with strong anti -static capabilities have long life, so the price is high. LED lamp beads that are usually more than 700V can be used for LED lighting. 5. Leakage current LED lamp bead is a unidirectional conductivity luminous body. If there is a reverse current, it is called LED lamp beads with large leakage currents. The life span is short and the price is low. What brand of lamp beads can reach 500 lumens LED lamp beads. This is a lamp bead that uses T6. The brightness is still very good. It is about 500 lumens. Both brightness and workmanship are much better. I have bought the two brands of this brand, and I bought one for myself. 500 watts of LED fever is the same Generally, downlights are three to five watts. This power is all used to fever and it is not hot, not to mention that the LED luminous rate is very high. First of all, the LED lamp beads are the manufacturers who will heat up during the work process. You can see the heat dissipation problem of the heat dissipation. 500 beads solar lamps can be shined in the area of \u200b\u200b10 square meters The more the number of lamp beads of solar LED street lamp head, the better, the better. When you encounter integrity manufacturers, you will give you a single 1W high -power high -light bead. If you encounter a bunch of inferior and cheap lamps, you will tell the customer that the more the lamp beads are. Of course, again, the integrity solar street light manufacturers will not push the customer of 6 meters 80 watts of 100 watts of solar lamps. The brightness of the LED lamp head with 30 watts and 40 watts is enough. It must be pushed to push 80-100 watts. The overall price of solar street lights has increased sharply, but also seriously wastes resources. So when you buy solar LED street lamp heads, don't count the lamp beads. Video directly to see the test brightness of the manufacturer's lamp head. The brightness can be visible to count. The above is the answer to the detailed explanation of 500LED lamp bead LED lamp bead parameters and related questions. I hope it will be useful to you [Responsible editor: a dream] |
