LED flat light structure analysis and planning considerations

the structure of the surface light source first has the following information:1. Aluminum Structureappearance structure, and the main structure of the LED heat dissipation-usually using AL6063, aluminum extrusion die, the upfront cost of low investment, the appearance of beautiful treatment, heat dissipation, the previous days to see the exhibition also found that there are manufacturers to do die-casting structure, so the IP level can do a higher point, and seal the light better, all beautiful,

Study on the Influence of optical fiber nonlinear effects on optical OFDM signals (1)

Study on the Influence of optical fiber nonlinear effects on optical OFDM signals (1) Optical Orthogonal Frequency Di-vision Multiplexing (O-OFDM) is a new type of Optical transmission technology that has been developed in recent years, it applies Orthogonal Fre-quency Division Multiplexing (OFDM) technology to optical fiber channels. Transmitting OFDM Signals in optical fiber channels can improve the spectrum utilization and resist dispersion and va

Basic Principles of focus (I)

1. Focus) When parallel light is injected into a convex lens, the ideal lens aggregates all the light to a point, which is called the focus. The focal length is the distance from the focal point to the convex lens optical center. 2. Circle of confusion) Before and after the focus point, the light from the aggregation to the diffusion, the point of the image from the circle to the point, and then spread to the circle, the front of the focus and the back of the circle, is called the

Fast development of optical communication testing technology

operation interface, the 10 Gbit/s optical port and electrical port can meet the R D, production, and testing needs for devices, modules, and subsystems, and can be used in field engineering installation and Fault Locating environments. However, due to the popularity of new Internet applications represented by P2P, IP traffic continues to increase rapidly. Currently, 10 Gbit/s-based long-distance WDM Networks are insufficient, some sections 80 × 10 Gbit/s have been used up, so the application

Hotelling T2 test and multivariate variance analysis

1.1 Hotelling T2 TestHotelling T2 test is a common multivariate testing method, which is a natural generalization of single-variable test, and is often used for the comparison of two groups of mean vectors.A sample of two content analysis is n,m from q-dimensional normal distribution N (μ1,∑), N (μ2,∑) with a common covariance matrix, to examineH0:μ1=μ2 h1:μ1≠μ2The average vector x, Y and the combined intra-group covariance matrix s are calculated for the mean value of each variable of two sampl

VariableThe variable value of variable can be divided into continuous variable and discrete variable. Continuous variables (continuous variable) and discrete variables (discrete variable)Continuous variablesIn a certain interval can be arbitrary value of the variable called continuous variable, its value is continuous, the adjacent two values can be infinite segmentation, that is, an infinite number of values.Discrete variablesA discrete variable is a discrete variable whose value can only be co
