[0002] With the development of science and technology, people's needs for light in modern society have gone beyond mere illumination. People have increasingly higher requirements for light, demanding various colors and applications. Similarly, the daily testing of mobile phones also requires specific lighting conditions.

[0003] For products with adjustable light, the existing similar products on the market are mainly of the following two types:

[0004] The first type is an open-type light-adjusting emitter, which generally consists of a light-emitting device (light bulb) and an external brightness control. Although this device can dynamically adjust the intensity and size of the light, it cannot read accurate luminance values, nor can it block interference from external light environments.

[0005] The second type is the large light-adjusting emission device used in factories. Although it can adjust the intensity and size of the light and block the influence of external light on the test, it is not convenient to move or carry.

[0006] Therefore, how to provide a portable light-adjusting transmitter that can dynamically read the luminous flux value of the adjustment device and isolate the influence of external light is an urgent problem to be solved. Utility Model Content

[0007] This invention provides a portable light-adjusting transmitter to solve the problem that existing light-adjusting transmitters cannot simultaneously possess portability, dynamically read the luminous flux value of the adjusting device, and isolate the influence of external light.

[0008] The technical solution of this utility model is a portable light-adjusting emitter, comprising: a housing, one end of which is recessed inward to form a receiving cavity, a light source assembly, a converging lens, and an emission window being sequentially arranged inside the receiving cavity and facing the opening; and at least one light flux sensor being provided between the converging lens and the emission window, and a light-shielding member being provided between the emission window and the corresponding receiving cavity;

[0009] The outer wall of the housing is equipped with a display screen and a current adjustment assembly;

[0010] The light source assembly is electrically connected to the current regulation assembly, and the display screen is electrically connected to the light flux sensor.

[0011] Furthermore, at least one light flux sensor is attached to the side of the light-shielding member facing the converging lens, and the light flux sensor does not block the emission window.

[0012] Furthermore, a baffle is provided at the opening of the receiving cavity, a transmission window is embedded in the baffle, and a light-shielding element is filled between the transmission window and the baffle;

[0013] Furthermore, the light flux sensor is closely attached to the side of the baffle facing the converging lens.

[0014] Furthermore, a power supply assembly is also provided inside the housing, which is electrically connected to the current regulation assembly, the light flux sensor and the display screen respectively.

[0015] Furthermore, the outer wall of the housing is provided with at least one charging port, which is electrically connected to the power supply assembly.

[0016] Furthermore, the light source assembly is surrounded by a heat dissipation device, which is used to dissipate the heat generated by the light source assembly during operation.

[0017] Furthermore, the outer wall of the housing is also provided with a switch assembly, which is connected to the light source assembly and is used to turn the light source assembly on or off.

[0018] Furthermore, the power supply component is a rechargeable battery.

[0019] Furthermore, the converging lens is a biconvex lens.

[0020] Furthermore, the material used to make the light-shielding component includes any one of sponge, foam plastic, and black rubber.

[0021] Compared with the prior art, the present invention has at least the following beneficial effects:

[0022] This invention can adjust the current passing through the light source component using a current adjustment component, thereby adjusting the light intensity of the light source component. The light emitted by the light source component then passes through a converging lens, which refracts the light into a uniform parallel beam and directs it towards the emission window. A luminous flux sensor then senses and measures the luminous flux of the parallel beam, and feeds back the measured value and displays it on the display screen. This allows the user to determine whether the luminous flux meets the test requirements by viewing the luminous flux value displayed on the screen, facilitating dynamic reading and adjustment of the luminous flux value. Furthermore, a light-shielding component can prevent light from escaping and optical interference from the external environment. Attached Figure Description

[0042] To make the technical problem to be solved, the technical solution, and the beneficial effects of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model. Therefore, a feature pointed out in this specification is used to describe one feature of one embodiment of the present utility model, and does not imply that every embodiment of the present utility model must have the described feature. Furthermore, it should be noted that this specification describes many features. Although certain features may be combined to illustrate possible system designs, these features may also be used in other combinations not explicitly stated. Therefore, unless otherwise stated, the described combinations are not intended to be limiting.

[0043] The principle and structure of this utility model will be described in detail below with reference to the accompanying drawings and embodiments.

[0044] This utility model includes the PCB board, wires, and corresponding components that are required for existing light-adjusting transmitters.

[0045] In some embodiments, such as Figure 1-2 As shown, this utility model proposes a portable light-adjusting emitter, comprising: a housing 10, one end of which is recessed inward to form a receiving cavity 111, a light source assembly 20, a converging lens 30, and an emission window 40 sequentially arranged inside the receiving cavity 111 and facing the opening; and at least one light flux sensor 50 is provided between the converging lens 30 and the emission window 40, and a light-shielding member 60 is provided between the emission window 40 and the corresponding receiving cavity 111;

[0046] The outer wall of the housing 10 is provided with a display screen 70 and a current adjustment component 80. The current adjustment component 80 is used to adjust the current passing through the light source component 20. When the current increases, the electrical power passing through the light source component 20 increases, the temperature of the light source component 20 rises, and the light intensity of the light source component 20 increases. Similarly, when the current decreases, the electrical power passing through the light source component 20 decreases, the temperature of the light source component 20 decreases, and the light intensity of the light source component 20 decreases.

[0047] The light source assembly 20 is electrically connected to the current adjustment assembly 80, and the display screen 70 is electrically connected to the light flux sensor 50.

[0048] It should be noted that, to ensure the portability of the portable light-adjusting transmitter, the housing 10 proposed in this embodiment is preferably cylindrical, with a diameter of approximately 80 mm and a length of approximately 150 mm. Of course, the shape of the housing 10 can also be prismatic or other easily portable shapes, which are not limited here; correspondingly, the values ​​of the diameter / width and length of the housing 10 can also be selected according to the actual situation, which are not limited here.

[0049] It is understood that the light source assembly 20 is located at the bottom of the receiving cavity 111, and the emission window 40 is located at or near the opening of the receiving cavity 111. The distance between the light source assembly 20 and the converging lens 30 is preferably the focal length of the converging lens 30. The emission window 40 is made of transparent material to prevent absorption and obstruction of light by colored materials, so that the light emitted by the light source assembly 20 can pass through the emission window 40 to illuminate the outside world.

[0050] Therefore, this utility model can adjust the current passing through the light source component 20 by the current adjustment component 80, thereby achieving the purpose of adjusting the light intensity of the light source component 20. Then, the light emitted by the light source component 20 passes through the converging lens 30, causing the light to converge at the real focal point of the converging lens 30. According to the principle that light is reversible, the light emitted from the real focal point to the converging lens 30 will be refracted into a uniform parallel beam after passing through the converging lens 30, so that the light directed towards the emission window 40 is evenly distributed. Then, the luminous flux sensor 50 senses and measures the luminous flux of the parallel beam, and then feeds back the measurement value and displays it on the display screen 70, so that the user can determine whether the luminous flux value required for the test is met by looking at the luminous flux value displayed on the display screen 70, thereby facilitating the dynamic reading and adjustment of the luminous flux value of the portable light-adjusting emitter; and the light shield 60 is used to prevent light from escaping and optical interference from the external environment.

[0051] In a further embodiment, the converging lens 30 is a biconvex lens. Because a biconvex lens is a spherical surface with two outwardly convex surfaces and is completely symmetrical on both sides, light entering from either side has the same effect; and because both surfaces are convex, the biconvex lens has a strong ability to converge light, so the focal length is usually shorter, which can further reduce the length of the housing 10 and improve portability; and the biconvex lens can better correct chromatic aberration, has better correction ability for spherical aberration and other aberrations, and has higher image quality; and when light passes through the biconvex lens, it undergoes two refractions, resulting in a more complex path, but allowing for better beam control.

[0052] Of course, in other embodiments, to control costs, the converging lens 30 can be selected as a plano-convex lens, with one side being a flat surface and the other side being an outwardly convex spherical surface.

[0053] In a further embodiment, to reduce the measurement error of the light flux sensor 50, such as Figure 1 As shown, at least one light flux sensor 50 is attached to the side of the light shield 60 facing the converging lens 30, and the light flux sensor 50 does not block the emission window 40.

[0054] In some embodiments, such as Figure 1 As shown, a baffle 130 is provided at the opening of the receiving cavity 111, a transmission window 40 is embedded in the baffle 130, and a light-shielding member 60 is filled between the transmission window 40 and the baffle 130.

[0055] Furthermore, the light flux sensor 50 is closely attached to the side of the baffle 130 facing the converging lens 30.

[0056] Understandably, the baffle 130 is made of an opaque material. Furthermore, the emission window 40 is positioned through the baffle 130.

[0057] In this way, the baffle 130 can better block external dust, moisture and other pollutants from entering the cavity 111 or the housing 10, and can further reduce the interference of external light on the light flux sensor 50, ensuring measurement accuracy.

[0058] In a further embodiment, the material of the light-shielding member 60 includes any one of sponge, foam plastic, and black rubber. Of course, the material of the light-shielding member 60 may also include black polyurethane foam or other light-absorbing materials, which are not limited here.

[0059] It should be noted that the material of the light-shielding component 60 proposed in this embodiment is preferably sponge, because sponge is soft and compressible, and can fit tightly against the edge of the emission window 40 to ensure good sealing; in addition, sponge has strong light absorption, and its porous structure can absorb and scatter light, reducing reflection; sponge is easy to process and can be cut into different shapes and sizes as needed; and sponge also has a cushioning and protective function, providing physical cushioning to protect sensitive components such as the emission window 40 from impact or vibration.

[0060] In some embodiments, such as Figure 1 As shown, the light source assembly 20 is surrounded by a heat dissipation device 110, which is used to effectively dissipate the heat generated by the light source assembly 20 during operation, thereby ensuring that the operating temperature of the light source assembly 20 is within a preset range and ensuring the stability and lifespan of the light source assembly 20.

[0061] It is understood that the light source component 20 proposed in this embodiment is circular in shape, and the heat dissipation device 110 is preferably an annular metal heat sink, with the light source component 20 located in the center of the heat dissipation device 110.

[0062] In some embodiments, such as Figure 1 As shown, the housing 10 also includes a power supply assembly 90, which is preferably a rechargeable battery; the power supply assembly 90 is electrically connected to the current regulating assembly 80, the light flux sensor 50, and the display screen 70.

[0063] The outer side wall of the housing 10 is also provided with at least one charging port 100, which is electrically connected to the power supply assembly 90.

[0064] In this way, the power supply component 90 can provide power to the entire portable light-adjusting transmitter, ensuring that the portable light-adjusting transmitter can work normally; and when the power supply component 90 is low on power, the charging port 100 can be connected to an external power source through a matching charging cable to charge the power supply component 90.

[0065] In some embodiments, such as Figure 1 As shown, the outer side wall of the housing 10 is also provided with a switch assembly 120, which is connected to the light source assembly 20 and is used to turn the light source assembly 20 on or off.

[0066] In some embodiments, such as Figure 2 As shown, the display screen 70, current regulation component 80, charging port 100 and switch component 120 are all integrated on an operation panel 140, which is located on the outer side wall of the housing 10.

[0067] The power supply component 90 is located inside the corresponding operation panel 140 of the housing 10, or the power supply component 90 is located inside the operation panel 140, which is not limited here.

[0068] The method of using this utility model is as follows:

[0069] The user first presses the switch assembly 120, and the light source assembly 20 emits light. The light is emitted through the emission window 40 and directed to the outside. Then, the user adjusts the current adjustment assembly 80 to change the intensity of the light emitted by the light source assembly 20. At this time, the display screen 70 receives the luminous flux of the light passing through the converging lens 30, measured by the luminous flux sensor 50. The user then uses the luminous flux value displayed on the display screen 70 to determine whether the required luminous flux value for the test has been met. If not, the user adjusts the current adjustment assembly 80 again until the luminous flux value displayed on the display screen 70 reaches the required luminous flux value for the test. Then, the user aligns the emission window 40 with the object being tested to perform the test. After the test is completed, the user only needs to press the switch assembly 120 again to stop the entire portable light adjustment transmitter from working.

[0070] Obviously, the embodiments described above are only some embodiments of this utility model, not all embodiments. The accompanying drawings show preferred embodiments of this utility model, but do not limit the patent scope of this utility model.
