[0001] The present invention relates to the technical field of lamp circuit board testing, and in particular to a circuit board testing device for an intelligent lamp. Background Art

[0002] In recent years, urban night scene lighting in my country has gradually received great attention from people, and the urban night light environment and landscape image have become an inseparable part of the urban landscape. Urban night scene lighting has roughly gone through three stages: initial creation, development, and popularization. Urban night scene lighting has not only made great progress in lighting technology, but also experienced the development process of "dark-bright", "bright-beautiful", and "beautiful-elegant" in lighting quality. From lighting methods to expression techniques, from lighting effects to the audience's aesthetic cognition, and even the relationship between night scenes and urban life or the coordination of major events, there have been very great changes. Excellent night scene lighting, through the appropriate depiction and scheduling of light, can well promote the external image of the building and the inner spirit and morphological meaning it carries, so that the night scene of the building exudes a charm that is worth savoring for a long time.

[0003] Outdoor lighting fixtures can be divided into two categories: one is always on, that is, the brightness, color, and color temperature are constant; the other is with intelligent control, that is, the brightness, color, and color temperature can be changed as required to meet the design effect. In outdoor landscape lighting projects, the proportion of intelligent control lamps is increasing year by year.

[0004] The electronic circuit design of intelligent control lamps is complex, with numerous electronic components. Usually, they are designed into two relatively independent PCB boards, namely the control board and the light source board. The control board is arranged with control chips and other electronic components, and the light source board is arranged with LED lamp beads. The two are connected by cables or pin headers.

[0005] In the mass production process, the control board and light source need to be tested separately, including the circuit, disconnection, controlled conditions, etc. Since PCB boards usually exist in the form of multiple panels, testing PCBs one by one is time-consuming, labor-intensive, and inefficient.

[0008] Furthermore, a pneumatic button is arranged on the upper surface of the cabinet, and the pneumatic button is connected to the motion mechanism. When the pneumatic button is triggered, the motion mechanism can move in a direction perpendicular to the bottom surface inside the cabinet.

[0009] Furthermore, a test button is provided on the upper surface of the cabinet, and the test button is connected to the controller. When the test button is triggered, the controller can send a test signal to the circuit board to control the electrical performance test of the circuit board.

[0026] like Figure 1 As shown, the cabinet 10 includes three layers from top to bottom, namely a first layer 11, a second layer 12 and a third layer 13.

[0027] Specifically, the test probe board of the second layer 12 is composed of five rows of test probes arranged on a transparent acrylic board.

Similarly, the PCB board is tested section by section. The 4 LED digital tubes can be turned 180 degrees to facilitate the test of the control board or light source board.

[0036] When the control board in the circuit board needs to be tested, first place a light source board with a completed patch at the position of the light source board on the third layer 13, and use the light source board as a load. Press the pneumatic button 60, the cylinder works, pushes the probe board on the second layer 12 downward, and connects the control board to the light source board one by one through the probe, and supplies power to the control board and sends signals at the same time. Press the button under the instrument one by one, the LED digital tube displays the current data, and judge whether the control board has quality problems based on the current figures.
