　　The performance of security inspection equipment has improved a lot compared with previous years. Security inspection X-ray machines are essential equipment for security inspection channels. How this equipment can distinguish dangerous items such as explosives, drugs, guns, knives, etc., we need to start with the principle of security inspection machines.

　　x-ray machines

　　ZA5030A

　　The security inspection machine is an electronic device that uses a conveyor belt to send the checked luggage into the X-ray inspection channel to complete the inspection. When the luggage enters the X-ray inspection channel, it will block the package detection sensor, and the detection signal will be sent to the system control part, generating an X-ray trigger signal, triggering the X-ray source to emit an X-ray beam.

　　The X-ray beam passes through the inspected objects on the conveyor belt, and the X-rays are absorbed by the inspected objects and finally bombard the semiconductor detector installed in the channel. The detector converts the X-rays into signals, and these very weak signals are amplified and sent to the signal processing chassis for further processing. After these signals are processed, they are displayed on the display screen.

　　”No matter how many layers a package has, X-rays can penetrate it and display the items in the package layer by layer.” Dangerous items are identified by different colors. Multi-energy colored organic matter is displayed in orange, inorganic matter is displayed in blue, and mixtures are displayed in green. High energy/low energy are switched to display. High energy displays metals, etc., and low energy displays non-metals. In the image display system, the X-ray sensor L-shaped photodiode array detector (multiple energies are optional), 12-bit depth, high penetration display increases the brightness of dark areas in the image, so that items hidden behind highly absorbent objects are clearly displayed. Low penetration display increases the contrast of low absorption (easy to penetrate) objects, making easy to penetrate objects clearer; therefore, the X-ray security inspection machine is not a decoration, but actually undertakes the work of protecting railway safety.

　　So how does the security inspection machine detect these dangerous items?

　　1. Image monitoring method

　　Image monitoring method directly determines the object from the X-ray image configuration. Therefore, whether the object is suspicious depends on the image on the monitor or display. Unusual objects or objects with different shapes that appear on the display or monitor should be considered suspicious objects. Objects that cannot be accurately identified should also be considered suspicious objects and need to be carefully investigated. The image can be located and analyzed as needed.

　　2. Color analysis method

　　The color analysis method is to identify the type of material based on the different colors that different materials show under the x-ray image. The various colors that appear on the monitor are a reflection of the density, quality and quantity of the object. Therefore, the quality of the object can be evaluated based on the depth of the image color.

　　Light yellow is generally the color of a single piece of clothing, thin plastic, and a small amount of paper.

　　Orange is generally the color of soap, soap, explosives, drugs, wood, leather products, etc.

　　Dark orange is generally the color of a large number of books, paper, RMB, high-concentration liquids, large bags of rice and flour, etc.

　　Blue is the color of inorganic substances such as copper, iron, and zinc. Thick cables, stun guns, bullets, gun barrels, guns, and knives show different shades of blue. Green is the color of mixtures, stainless steel products, cables, etc. show different shades of green. Red is the color of impenetrable objects, mostly heavy metals and thick objects.

　　LED car lights refer to lamps that use LED technology for external and internal lighting in both the light sources inside and outside the car. External lighting equipment is about thermal limits and EMC. Use LED car lights to create an in-car environment with a lifespan of 50,000 hours. The structure of LED is sturdy and not easily affected by vibration, and the light output brightness will not decrease significantly during use.By comparison, it can be seen that led emergency warning lights It has certain advantages and great cost performance. https://www.lkx-mascarello.com

　　LED car lights are suitable for various lighting applications in automotive electronics, including headlights (high beam and low beam), fog lights, tail lights, brake lights, turn signals, daytime running lights, pedal lights, instrument lights, license plate lights, door lights, interior lights, width lights, navigation, entertainment systems, backlights and indicator lights. 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.

　　It is not possible to generalize between memory foam pillows and latex pillows. It depends on personal pillow needs. First of all, let us understand the essential difference between them. As the name implies, their essential difference is the material. In terms of touch, latex material will be softer than memory foam. If it is a real natural latex or a latex pillow with a high content, although it is soft, its support is also very good. Secondly, in terms of the effectiveness of the pillow, the memory foam material has the characteristic of automatic temperature adaptation at 37 degrees. When the human body contacts the pillow, the pillow will automatically fit the cervical spine, perfectly fitting the physiological curvature of the cervical spine. Therefore, if you are purchasing for the purpose of cervical health care or cervical repair, then the memory foam pillow is obviously better than the latex pillow.If we can practice these points, memory foam pillow Will be unique, become a leader in the industry, and keep moving forward. https://tainengjikang.com/

　　In-depth analysis: Which is better, a memory foam pillow or a latex pillow?

　　We can choose whether to buy a memory foam pillow or a latex pillow based on our personal needs and the following situations.

　　In-depth analysis: Which is better, a memory foam pillow or a latex pillow?

　　1. Latex is a relatively environmentally friendly material. The premise of this environmental protection is natural latex. The pillow made of real pure natural latex has excellent antibacterial and anti-mite effects, which is very suitable for infants and young children who have high requirements for anti-mite and anti-bacterial. In addition, latex feels very soft, but still has a certain degree of support, which is suitable for people who like to sleep on soft pillows.

　　2. The main function of memory foam is to absorb the pressure of the cervical spine and relieve the cervical spine. If used consistently, it can maintain the physiological curvature of the cervical spine at 12＼5. Due to its professionalism in cervical spine repair, memory foam is very suitable for people with sub-healthy cervical spine or cervical spine lesions. Using it all night can help users repair the cervical spine during sleep and effectively relieve the discomfort of the cervical spine caused by strain.

　　3. In terms of smell, newly produced memory foam has a slight smell, but this smell is harmless to the human body. Generally, the smell of memory foam pillows disappears in about 3-5 days. The real natural latex pillow has a very strong latex smell, which generally fades in 3 to 6 months, but there will always be a faint latex smell that will not disappear. Therefore, if you are very sensitive to smell, it is recommended to choose a memory foam pillow.

　　4. In terms of service life, latex material has a natural fatal weakness, that is, it ages very quickly. During use, latex material will oxidize with air, and after oxidation, it is easy to shed small dandruff on the surface and produce odor, and the pillow will become hard, which will not provide any support for the cervical spine. Although under normal circumstances, it is recommended to replace the pillow every 2 to 3 years to prevent bacterial growth, if the pillow has begun to age before it is replaced, it will not have any positive effect on the cervical spine.

　　In-depth analysis: Which is better, a memory foam pillow or a latex pillow?

　　If it is used daily to protect the vertebrae and relieve the cervical spine, it is recommended to choose memory foam or latex material. Of course, if the focus is on the neck protection function, memory foam is definitely more preferred. The most intuitive difference between these two materials is that the real memory foam material feels harder than real latex or latex pillows with a high latex content. The real natural latex material or latex pillow with a high latex content feels quite soft, but both have very good support. Of course, this premise is that you buy high-quality products. If it is a memory foam with talcum powder added, or a latex pillow made of synthetic latex, its effect and comfort level will be greatly reduced.
