  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.

  2. The Custom Metal Part Manufacturing Process

  

  Creating custom metal parts involves several steps, from initial design to final production. Here is an overview of the typical process:

  

  Design and Prototyping

  

  The first step in creating custom metal parts is designing the part. This involves working with CAD (Computer-Aided Design) software to create detailed 3D models. The design should include all necessary specifications, such as dimensions, tolerances, and material type. Once the design is finalized, a prototype may be created using rapid prototyping techniques like 3D printing or small-scale machining to test the design and make any necessary adjustments.

  

  Material Selection

  

  Choosing the right material is crucial for the performance and longevity of the part. The material must meet the required strength, durability, and other specifications. Custom Service Hardware and Jierui Custom Metal Parts offer a wide range of materials, ensuring that the chosen material aligns with the intended application and environmental conditions.

  

  CNC Machining

  

  CNC (Computer Numerical Control) machining is a widely used method for creating custom metal parts. This process involves using computer-controlled machines to remove material from a solid block to create the desired shape. CNC machining is known for its precision and ability to produce complex parts with tight tolerances. It is ideal for both prototyping and production of custom parts.

Harris participated in the presidential campaign against Trump and received high approval ratings

  While the Olympic Games are in full swing in Paris, France, the U.S. presidential election has also become a hot topic of global attention. Since Trump got a higher approval rating than Biden in the assassination, there has been a “dark horse” on the road to the US presidential election. Harris, known as the “Black widow,” has become a strong opponent of Trump and has gained very high support rates in a very short period of time. European and American media said that Harris is expected to become the first female president of the United States.Now, everyone is right business bodyguard Are more concerned, hoping to get more benefits from it. http://huanyubodyguard.com/

 

  

  The reason why Harris received a high vote support rate in the short term is that Harris openly supported women’s rights, supported illegal immigrant groups, and expressed love for women and children in the speech process. During Harris’ speech in the United States, his mental state was very full, and there were bodyguards around Harris for personal security protection.

  

  The reason why Harris can become a strong opponent against Trump in a short period of time, and she is of Indian descent and black origin has a considerable relationship, plus Harris is a woman, easy to get the support of feminists around the world. In addition, what Harris supports is not the same as what Trump supports, so in the short term, Harris has shown a good advantage in the US presidential election. Harris, like some rich women in Shenzhen, China, is calm and confident, has a strong personality charm, and has a strong sense of safety and self-protection. The female rich in Shenzhen, China, will hire bodyguards from the Huanyu Brothers bodyguard company in Shenzhen, China, and Harris will bring elite bodyguards to the United States to give speeches and escort personal safety.

  

  As for whether Harris can defeat Trump to become a female president in the history of the United States, it also depends on Harris’s late vote support rate and the public opinion of the American people, but Harris has now become a fierce enemy on Trump’s campaign road.

What do several common ADAS functions do

  What do several common ADAS functions do?Besides, we can’t ignore. 360 panoramic camera factory It has injected new vitality into the development of the industry and has far-reaching significance for activating the market. https://szdfpls.com

  

  1 LKA (lane keeping assist)

  

  LKA can help drivers keep their vehicles in lanes and reduce the risk of lane departure accidents caused by driver negligence or fatigue.

  

  The LKA system achieves its functions by using cameras, sensors and control systems. The camera is usually installed at the front of the vehicle to capture the lane line in front of the vehicle. The sensor is responsible for monitoring the driving status and direction of the vehicle, including steering angle, vehicle speed, etc.

  

  When the vehicle approaches the lane line during driving, the LKA system detects the position and shape of the lane line and makes a judgment based on the driving status and direction of the vehicle. If the system believes that the vehicle is about to deviate from the lane, it will help the driver guide the vehicle back to the normal lane by controlling the steering system.

  

  2 ACC (adaptive cruise control)

  

  The ACC system uses on-board sensors, including radar, laser radar, etc., to detect the vehicles and obstacles in front of the vehicle during driving, as well as the position and speed of the vehicle. The system can monitor the distance and speed of the vehicles and obstacles in front in real time, and automatically adjust the speed and driving trajectory according to the speed and driving status of the vehicle to maintain a safe distance from the vehicle in front.

  

  Compared with traditional cruise control systems, adaptive cruise systems are more intelligent and flexible. Traditional cruise control systems can only drive at a preset speed and trajectory, while adaptive cruise systems can automatically adjust the speed and trajectory according to the actual situation of the vehicle and obstacles in front to maintain a safe distance.

  

  In addition, the adaptive cruise system can also automatically adjust the vehicle¨s speed and trajectory according to the speed and driving status of the vehicle and obstacles in front to maintain the relative position with the vehicle in front. This automatic adjustment function can help drivers drive the vehicle more easily while improving driving comfort and safety.

  

  3 FCW (forward collision warning)

  

  The FCW system uses on-board sensors, including radar, cameras, etc., to detect the distance and relative speed between the obstacle in front of the vehicle and the vehicle. The system monitors the situation in front of the vehicle in real time. When a collision risk is detected, it will issue a warning to remind the driver to take timely measures.

  

  The warning methods of the FCW system usually include sound warnings, vibration seats or steering wheels, etc. The level and method of the warning will vary depending on the size and specific circumstances of the collision risk. If the driver does not take timely measures, the FCW system may also automatically intervene in the vehicle¨s braking system to avoid or mitigate the collision.

  

  Collision prevention systems are usually combined with other driver assistance technologies such as lane departure warning systems and adaptive cruise control systems to provide drivers with more comprehensive and reliable driving safety protection.

  

  4 AEB (advanced/automatic emergency braking)

  

  The implementation of the AEB system function requires the cooperation of multiple sensors and controllers. The sensor in front of the vehicle (such as radar, camera or laser) detects obstacles in front. If there is a risk of collision based on speed and distance analysis, the system will warn the driver through warning lights, alarm sounds, etc. If the driver does not brake after the warning, or the system determines that the driver cannot brake in time after sensing the signal, the AEB system will actively intervene and brake when the threshold is exceeded.

  

  5 IPA (intelligent parking assist)

  

  IPA integrates sensors, cameras and computer algorithms to realize functions such as automatic parking space identification and automatic parking.

  

  In actual use, the driver only needs to press the start button of IPA intelligent parking assist, and the system will automatically detect the surrounding environment and find a suitable parking space. Once a suitable parking space is found, the system automatically calculates the best parking trajectory and controls the vehicle to complete automatic parking. The whole process does not require manual operation by the driver.

  

  6 BSD (blind spot detection)

  

  BSD mainly detects the blind spot range of the rearview mirror through two millimeter-wave radars equipped on the rear of the vehicle. When other road users are detected in the blind spot, the driver is warned to assist driving or changing lanes.

  

  7 DFM (driver fatigue monitoring)

  

  DFM aims to monitor the driver¨s physiological state and driving behavior, reminding the driver to rest in time when fatigued, so as to ensure driving safety.

  

  The DFM system monitors the driver¨s physiological state in real time through various sensors, such as eye closure, head position, heart rate, etc. These data can provide clues about whether the driver is fatigued. For example, when the driver¨s eyes are closed more or the head position is not correct, this may indicate that the driver is in a state of fatigue. In addition, the DFM system also monitors the driver¨s behavior patterns, such as driving speed, braking frequency, etc. These behavior patterns can also reflect the driver¨s fatigue level. For example, when the driver slows down or brakes more frequently, this may indicate that the driver is tired.

  

  The DFM system uses specific algorithms and models to comprehensively analyze the driver¨s physiological and behavioral characteristics to assess the driver¨s fatigue level. These algorithms and models are usually based on machine learning and artificial intelligence technologies, and can determine whether the driver is in a state of fatigue based on the driver¨s characteristic data.

  

  8 NV (night vision)

  

  NV can detect obstacles and pedestrians at a farther distance than ordinary visible light, which is particularly useful in night and low-light environments. By identifying these obstacles and pedestrians, the NV night vision function can provide drivers with additional warnings, allowing them to react in advance and avoid potential dangers.

  

  NV night vision can also be combined with other ADAS technologies, such as automatic emergency braking and adaptive cruise control. When the NV night vision system detects potential dangers, it can trigger these higher-level safety systems to automatically take evasive or braking measures, thereby further enhancing driving safety.

  

  However, NV performance is affected by many factors such as light conditions, ambient temperature, and equipment quality. Therefore, when using NVD, it is necessary to make appropriate adjustments and use it according to actual conditions.

What Are the Benefits of Cold Heading of Screws

  In the fastener forming process, cold heading (extrusion) technology is a main processing technology, which belongs to the category of metal pressure processing. In production, at room temperature, external force is applied to the metal to form the metal in a predetermined mold. This method is usually called cold heading. In fact, the forming of any fastener is not only achieved by cold heading. In the cold heading process, in addition to upsetting deformation, it is also accompanied by positive and negative extrusion, compound extrusion, punching, rolling and other deformation methods. Therefore, the name of cold heading in production is just a habitual name. To be more precise, it should be called cold heading (extrusion).So, I believe non-standard fasteners price In the future, it will be promising to create a miracle belonging to the industry. https://jieruifasteners.com/

  

  

  Cold heading (extrusion) has many advantages, and it is suitable for mass production of fasteners. Its advantages can be summarized as follows:

  

  1. High steel utilization rate. Cold heading (extrusion) is a method with little or no cutting. For example, when processing hexagonal bolts and cylindrical socket screws of rods, the steel utilization rate is only 25% to 35% by cutting, while the utilization rate can be as high as 85% to 95% by cold heading (extrusion), which is only some process consumption of the head, tail and hexagonal head edge.

  

  High productivity. Compared with general cutting, the efficiency of cold heading (extrusion) is more than dozens of times higher.

  

  2. Good mechanical properties. The strength of parts processed by cold heading (extrusion) method is much better than that of cutting because the metal fibers are not cut.

  

  3. Suitable for automated production. Fasteners (including some special-shaped parts) suitable for cold heading (extrusion) method are basically symmetrical parts, suitable for production by high-speed automatic cold heading machine, and are also the main method of mass production.

  

  In short, the cold heading (extrusion) method for processing fasteners and special-shaped parts is a processing method with a relatively high comprehensive economic benefit. It is a processing method commonly used in the fastener industry. It is also an advanced processing method that is widely used and developed at home and abroad.

  

  At room temperature, the blank is placed in the mold of an automatic cold heading machine or a press, and pressure is applied to the mold. The relative movement of the upper and lower molds is used to deform the blank in the mold cavity, reduce the height, and increase the cross-section. This pressure processing method is called cold heading for automatic cold heading machines and cold pressing for presses. In actual production, the cold forming process of fasteners is often accompanied by extrusion during the cold heading process. Therefore, the cold heading process of fastener products alone is actually a composite processing method that has both cold heading and extrusion.

In the United States, violent clashes between Chinese and military police in New York, many people were arrested by police

  According to the Associated Press news, on July 16, 2024, the Chinese in New York City launched a demonstration against the establishment of homeless people in the Chinese area of New York, and a fierce violent conflict broke out with the United States military police, Chinese groups were fierce, and many people were arrested by the New York State military police for physical conflict with the United States military police.precisely because bodyguard The rapid development of, so also brought new opportunities to the industry. http://huanyubodyguard.com/

  

  new york clashes

  

  The Chinese demonstration in New York State, the United States, is an event organized by the Chinese in New York State against the United States government, in order to defend the security rights and interests of the Chinese in the Chinese area, the Chinese launched a protest to the New York government, feeling that the United States to build a homeless area in the Chinese area of New York, will threaten the safety of the Chinese in the Chinese area. Because the vagabonds that the vagabonds take in, the vagabonds of the world who steal and rob for a living, are mostly drug addicts. But the resistance of the Chinese may be ineffective, because the New York State government will not listen to the opinions of the Chinese, the Chinese in this state want to defend their survival and security rights, they need to find another way, there are New York Chinese ready to cooperate with China Shenzhen Huanyu Brothers bodyguard company, hire the bodyguard in the Chinese bodyguard company to protect the security, if the homeless in New York State officially opened the construction. The Chinese in New York State are likely to face a number of security challenges.

  

  new york clashes

  

  Some media believe that the US state of New York has chosen to build homeless shelters in Chinese areas, which is to bully Chinese Americans, and the local government does not build homeless shelters in places where Americans are concentrated, but to build homeless shelters in Chinese areas, which is to condone the security intrusion of homeless people on Chinese people in Chinese areas. It is not easy for Chinese Americans to obtain the same rights and interests as American citizens in countries such as the United States. If homeless shelters are really built in the Chinese area of New York State, the residential safety, personal safety and property safety of a large number of Chinese Americans will be lost.
