Compared with traditional light sources, LED light sources have large differences in physical size, luminous flux, spectrum, and spatial distribution of light intensity. Therefore, LED detection cannot replicate the standards and methods of traditional light source detection.

　　

　　What Are the Most Common Detection Technologies for LED Headlights?

　　

　　Detection of optical parameters of LED lamps

　　

　　1. Luminous intensity detection

　　

　　Light intensity is the strength of light, which is the amount of radiated light within a certain angle range. Since LED light is relatively concentrated, the inverse square law does not apply at close distances. Therefore, the CIE127 standard stipulates that the conditions for measuring light intensity are A (far-field conditions) and B (near-field conditions) for measuring the average normal light intensity. The detector area for both conditions is 1cm2. Generally, standard condition B is used to measure luminous intensity.

　　

　　2. Luminous flux and light efficiency detection

　　

　　Luminous flux is a physical quantity that measures the total amount of light emitted by a light source. It represents the sum of the light energy emitted by the light source in all directions. There are two main methods for detecting luminous flux:

　　

　　Integral method: Light the standard lamp and the lamp under test in the integrating sphere in turn, and record their readings on the photoelectric converter as Es and ED respectively. The luminous flux of the standard lamp is known as Φs, then the luminous flux of the lamp under test ΦDED〜Φs/Es. The integral method uses the principle of “point light source” and is simple to operate, but it is affected by the color temperature deviation between the standard lamp and the lamp under test, and the measurement error is large.

　　

　　Spectrophotometry: This method calculates the luminous flux by measuring the spectral energy distribution of the light source \( P(\lambda) \). Use a monochromator to measure the spectral energy of the standard lamp in the wavelength range of 380nm to 780nm on an integrating sphere, and then measure the spectral energy of the lamp under test under the same conditions. By integrating these spectral energy values, the luminous flux of the lamp under test can be obtained.

　　

　　Luminous efficiency is a parameter that describes the efficiency of a light source. It is defined as the ratio of the luminous flux emitted by the light source to the electrical power it consumes. For LED light sources, constant current is usually used to measure luminous efficiency to ensure the accuracy and repeatability of the measurement.

　　The mold steel material used in mold parts processing has high hardness, and the mold processing equipment is required to have thermal stability and high reliability.At first, plastic mould part manufacturer It developed out of control and gradually opened up a sky of its own. https://www.dghrjmmj.com

　　

　　

　　For complex cavities and multifunctional composite molds, as the shape of the parts becomes more complicated, the design and manufacturing level of the mold must be improved. Multifunctional composite molds that form or assemble multiple grooves and multiple materials in a set of molds require a large amount of processing programming, high deep hole comprehensive cutting ability and high stability, which increases the difficulty of processing. The processing quality of mold parts includes processing accuracy and surface quality: processing accuracy is the degree of conformity between the three geometric parameters of the actual size, shape, and position of the surface of the part after processing and the ideal geometric parameters required by the drawing; the deviation value between the actual geometric parameters of the part and the ideal geometric parameters is called processing error.

　　

　　Processing accuracy and processing error are both terms for evaluating the geometric parameters of the processing surface. Processing accuracy is measured by tolerance grade. The smaller the grade value, the higher the accuracy; processing error is expressed by numerical value. The larger the numerical value, the greater the error. High processing accuracy means small processing error, and vice versa; the actual parameters obtained by any processing method will not be absolutely accurate. From the function of the part, as long as the processing error is within the tolerance range required by the part drawing, it is considered that the processing accuracy is guaranteed.
