Technical Field
[0001] This utility model relates to the field of stray light testing technology for vehicle-mounted cameras, specifically to an ultra-high brightness point light source. Background Technology
[0002] In the modern automotive industry, performance testing of onboard cameras is crucial. Among these, glare testing (QCT1128, ISO16505, GB15084), ghosting testing (QCT1128), and point light source testing (GB15084, UN-R46) are key stages. However, traditional point light source equipment suffers from the following problems:
[0003] 1. Insufficient brightness: It cannot meet the high brightness requirements of some standards.
[0004] 2. Flickering problem: Traditional driving methods are prone to causing light source flickering, which affects the accuracy of test results.
[0005] 3. Low adjustment precision: The brightness adjustment range is limited, making it difficult to achieve precise control.
[0006] 4. Difficulty in calibration: The lack of effective self-calibration function leads to a decline in the long-term stability of the test equipment.
[0007] Therefore, it is particularly important to design a point light source device that can fully meet the above testing standards and has high brightness, flicker-free operation, high-precision adjustment and self-calibration functions. Utility Model Content
[0008] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide an ultra-high brightness point light source that fully considers the actual needs of vehicle-mounted camera testing. It has the characteristics of high brightness, high precision adjustment, no flicker, and convenient calibration, and fully meets the requirements of testing standards such as QCT1128, ISO16505, GB15084 and UN-R46.
[0009] To achieve the above objectives, this utility model is implemented through the following technical solution: an ultra-high brightness point light source, including an LED light board PCB, a housing assembly, a light source control cable, a cooling fan, and a control box. The LED light board PCB is disposed inside the housing assembly. A point light source control cover is provided on the front side of the housing assembly. A cooling fan is provided on the back side of the housing assembly. The LED light board PCB is connected to the control box through the light source control cable.
[0010] Preferably, the housing assembly is a magnetically attached housing.
[0011] Preferably, the LED light board PCB is a light board PCB with three LEDs.
[0012] Preferably, the point light source control cover is a single point light source control cover or a double point light source control cover.
[0013] Preferably, the light-emitting hole of the single-point light source control cover is located in the middle.
[0014] Preferably, the light-emitting holes of the dual-point light source control cover are located on both sides.
[0015] This utility model has the following beneficial effects:
[0016] 1. High brightness: The brightness of the central LED point light source can reach 5 million cd / m². 2 It fully meets all kinds of testing standards.
[0017] 2. High-precision adjustment: 4000 levels of brightness adjustment range, linear constant current drive, ensuring no flicker.
[0018] 3. Multifunctionality: It supports glare testing, ghosting testing and point light source testing at the same time.
[0019] 4. Convenient calibration: Quick calibration is achieved through software and external measuring equipment, improving testing efficiency.
[0020] 5. Long lifespan: Service life exceeds 20,000 hours, reducing maintenance costs. Attached Figure Description

[0026] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.
[0027] Example 1: Refer to Figure 1-3This embodiment provides an ultra-high brightness point light source, including a control box 1, an LED light board PCB 6, a housing assembly 2, a light source control cable, and a cooling fan 3. The LED light board PCB is disposed inside the housing assembly 2. A single-point light source control cover 4 is disposed on the front side of the housing assembly 2, and a cooling fan 3 is disposed on the back side of the housing assembly 2. The LED light board PCB 6 is connected to the control box 1 through the light source control cable (the control box controls the brightness of each group of light sources with high precision by connecting the light source control cable on the light source assembly). The light outlet hole of the single-point light source control cover is disposed in the middle and is precisely positioned and fixed in front of the light source assembly by magnetic attraction to achieve the light output effect of a single point light source.
[0028] It is worth noting that the outer shell assembly 2 is a magnetically attached outer shell.
[0029] It is worth noting that the LED light board PCB is a light board PCB with three LEDs.
[0030] The highest brightness of the central LED point light source in this embodiment is ≥5,000,000 cd / m². 2 It fully meets the glare test requirements of QCT1128, ISO16505 and GB15084; at the same time, the LED can achieve an illuminance of 200±20lx at a distance of 40cm through brightness adjustment, which fully meets the point light source requirements for ghost image test in QCT1128.
[0031] Example 2: Refer to Figure 4 The difference between this embodiment and Embodiment 1 is that this embodiment uses a dual-point light source control cover plate 5, with the light emission holes of the dual-point light source control cover plate 5 located on both sides. It is precisely positioned and fixed in front of the light source assembly via magnetic attraction, achieving a paired point light source emission effect and precisely controlling the light emission diffusion angle and light-emitting area of the light source. The maximum brightness of the two LED point light sources is ≥300,000 cd / m². 2 It fully meets the requirements for point light source testing in GB15084 and UN-R46. The software allows users to create, save, and recall preset light sources, and supports external measurement devices for rapid measurement and calibration of light sources. API functions can be used for client software self-calibration and integration.
