[0028] Please see Figure 1 , Figure 2 and Figure 3 The present invention provides an embodiment of a neon lamp brightness tester, comprising a test body 1, a neon lamp fixing mechanism 2, a photoelectric detection component 3, and a control display 4. An operating platform 5 is fixedly installed on the top of the outer wall of the test body 1, the neon lamp fixing mechanism 2 is fixedly installed on the top of the outer wall of the operating platform 5, the photoelectric detection component 3 is embedded inside the test body 1, and the control display 4 includes a circuit board connected to the inside of the test body 1 and a display screen 6 embedded in the outer wall of the test body 1.

[0029] The detection end of the photoelectric detection component 3 faces the clamping area of ​​the neon lamp fixing mechanism 2. The main circuit board is electrically connected to the power supply terminal, the photoelectric detection component 3 and the display screen 6 respectively. The front end of the clamping area of ​​the neon lamp fixing mechanism 2 is directly facing the photosensitive surface of the photodiode 19. The photodiode 19 is connected to the input end of the signal amplification circuit. The output end of the signal amplification circuit is connected to the main circuit board. The photodiode 19 is fixedly installed inside the photoelectric detection component 3.

[0030] Specifically, first, place the N1-23X10 neon lamp with a lead wire diameter of 0.15mm on the neon lamp fixing mechanism 2 of the operating platform 5. Adjust the horizontal adjusting slide rail 7 so that the two clamping blocks 9 of the vertical clamping rod 8 are aligned with the two ends of the neon lamp. Since the inner wall of the clamping block 9 has an arc-shaped groove 10 that complements the outer wall of the neon lamp, and there is an insulating pad 11 in the groove, after the neon lamp is inserted into the groove, the insulating pad 11 can prevent the neon lamp shell from conducting electricity with the clamping rod. Then, select a power supply terminal connector 12 with a diameter of 0.15mm and connect the lead wire of the neon lamp to the connector 12 to make the circuit conductive.

[0031] Then, press the operation button 17 on the control display 4. The main circuit board outputs a 110V drive voltage through the voltage regulator 15. The voltage is transmitted to the neon lamp through the power supply terminal to light it up. The photosensitive surface of the photodiode 19 in the photoelectric detection component 3 faces the neon lamp clamping area. The light signal emitted by the neon lamp is received by the photodiode 19 and converted into a weak electrical signal. The signal is amplified by the signal amplification circuit and transmitted to the main circuit board. The light shield 13 outside the photoelectric detection component 3 and the rubber sealing ring 14 at the opening end isolate external light interference to ensure that only the neon lamp light signal is detected.

[0032] Finally, the circuit board processes the amplified electrical signal, converts it into a brightness value, and displays it in real time on the display screen 6. During the test, the anti-slip pads 18 on the bottom of the test body 1 prevent the instrument from sliding, and the heat dissipation holes 16 on the side of the housing dissipate the heat generated by the circuit board in a timely manner.

[0033] Please see Figure 1 , Figure 2 and Figure 3The present invention provides an embodiment of a neon lamp brightness tester, wherein the neon lamp fixing mechanism 2 includes a horizontal adjustment slide rail 7, a vertical clamping rod 8 and a power supply terminal. The horizontal adjustment slide rail 7 is arranged along the length direction of the operating platform 5. The vertical clamping rod 8 is slidably connected to the horizontal adjustment slide rail 7. The power supply terminal is arranged on the inner side of the vertical clamping rod 8 and is connected to the lead wire of the neon lamp.

[0034] The longitudinal clamping rod 8 includes two clamping blocks 9 arranged opposite to each other. The inner side of the clamping block 9 is provided with an arc-shaped groove 10 that is complementary to the outer wall of the neon lamp. An insulating pad 11 is provided on the inner wall of the arc-shaped groove 10.

[0035] Specifically, first, select a high-brightness neon lamp of model NE-2H3810 with a lead wire diameter of 0.35mm. Place the neon lamp on the operating platform 5. Since the length of this model of neon lamp is 10mm, adjust the horizontal adjustment slide rail 7 to make the spacing of the vertical clamping rods 8 suitable. The arc-shaped groove 10 of the clamping block 9 fits the outer wall of the neon lamp. The insulating pad 11 prevents leakage. Replace the wiring head 12 of the power supply terminal with a 0.35mm diameter specification and connect the neon lamp lead wire.

[0036] Then, the test parameters are set by operating button 17. The circuit main board controls the voltage adjustment block 15 to output a 331V drive voltage. After the neon lamp is lit, the strong light signal is captured by the photodiode 19 of the photoelectric detection component 3. Since the high-brightness neon lamp light is strong, the signal amplification circuit automatically adjusts the amplification factor to avoid signal saturation and ensure linear conversion of the electrical signal. The rubber sealing ring 14 of the light shield 13 fits tightly against the surface of the operating platform 5 to further block ambient light from entering the detection area.

[0037] Finally, the brightness value processed by the circuit board is displayed on the display screen 6, and the positioning scale line helps to record the distance between the neon lamp and the photoelectric detection component.

[0038] Please see Figure 1 , Figure 2 and Figure 3 The present invention provides an embodiment of a neon lamp brightness tester, wherein the power supply terminal includes a replaceable connector 12, the diameter of which is adapted to neon lamp lead wires with diameters of 0.15mm, 0.35mm, 0.40mm, and 0.42mm respectively; a light shield 13 is fixedly installed on the outer wall of the photoelectric detection component 3, the opening end of the light shield 13 faces the neon lamp fixing mechanism 2, and a rubber sealing ring 14 is fixedly installed on the edge of the opening end;

[0039] The circuit board has an integrated voltage regulator block 15 on its outer wall, and the voltage regulator block 15 is connected to the power supply terminal.

[0040] Specifically, first, place the NE-2C-4X10.5 model quasi-high brightness neon lamp with a lead wire diameter of 0.35mm on the operating platform 5. Based on the length of the neon lamp (10.5mm), move the longitudinal clamping rod 8 along the horizontal adjustment slide rail 7. Confirm that the distance between the neon lamp and the photoelectric detection component 3 is 50mm by using the positioning scale line on the surface of the operating platform 5. The arc-shaped groove 10 of the clamping block 9 holds the neon lamp in place, the insulating pad 11 protects the lead wire insulation layer, and a 0.35mm diameter connector 12 is used to connect the lead wire.

[0041] Then, press the operation button 17 to start the test. The voltage regulator 15 outputs 351V voltage, the neon lamp lights up, and the photodiode 19 receives the light and converts it into an electrical signal, which is then transmitted to the main circuit board through the amplifier circuit. The light shield 13 effectively blocks external stray light, ensuring that the detection signal comes only from the neon lamp itself. The main circuit board also records parameters such as the power supply voltage and test distance, and processes them synchronously with the brightness signal.

[0042] Finally, display screen 6 shows the brightness value and test conditions.

[0043] Please see Figure 1 , Figure 2 and Figure 3 The present invention provides an embodiment of a neon lamp brightness tester, wherein the outer surface of the operating platform 5 is provided with positioning scale lines, which are distributed along the length direction of the transverse adjustment slide rail 7; the control display 4 also includes an operation button 17 fixedly installed on the front end of the outer wall of the test body 1, and the operation button 17 is connected to the circuit motherboard.

[0044] The test body 1 has heat dissipation holes 16 on the side of the shell. The heat dissipation holes 16 are arranged in an array along the height direction of the shell. A dustproof net is installed inside the heat dissipation holes 16. Anti-slip pads 18 are fixedly installed on the bottom of the outer wall of the test body 1.

[0045] Specifically, first, select the HF-2G632G model green plastic-cased glow lamp with a plastic cover, 20mm in length, and a plastic outer shell with a slightly irregular shape. Adjust the two clamping blocks 9 of the longitudinal clamping rod 8 so that the arc-shaped groove 10 fits against the outer wall of the plastic shell. The insulating pad 11 prevents the outer shell from conducting to the circuit. The lead wire diameter is 0.42mm. Replace the power supply terminal connector 12 with a 0.42mm diameter hole. After connecting the lead wire, confirm that the lamp head of the plastic-cased glow lamp faces the opening end of the photoelectric detection component 3.

[0046] Then, by selecting the "plastic shell lamp mode" using the operation button 17, the circuit main board controls the voltage adjustment block 15 to output 200V voltage, and the glow lamp is lit. The light shield 13 of the photoelectric detection component 3 covers the front end of the glow lamp, and the rubber sealing ring 14 seals the gap to prevent green light leakage from affecting the detection. The photodiode 19 is sensitive to the green spectrum. After converting the light signal into an electrical signal, it is transmitted to the main board through the amplification circuit. The main board compensates for the wavelength characteristics of green light.

[0047] Finally, display screen 6 shows the corrected brightness value. During the test, heat dissipation holes 16 continuously dissipate heat to ensure that the circuit board works stably during long-term testing.

[0048] Working principle: First, the neon lamp fixing mechanism mechanically fixes the neon lamp under test to the circuit. According to the size of the neon lamp model and the diameter of the lead wire, the horizontal adjustment slide rail is adjusted to match the spacing of the vertical clamping rods. Physical fixation is achieved by using the complementary arc-shaped grooves on the inner wall of the clamping block and the outer wall of the neon lamp. The insulating pad in the groove prevents the neon lamp shell from conducting electricity with the clamping structure. At the same time, a replaceable connector with the corresponding hole diameter is selected to connect the neon lamp lead wire to ensure the power supply circuit is conductive.

[0049] Then, the main circuit board controlling the display outputs a driving voltage adapted to the neon lamp model through a voltage regulator. The voltage is transmitted to the neon lamp through the power supply terminal to light it up. The light signal emitted by the neon lamp is received by the photodiode facing the clamping area and converted into a weak electrical signal. The signal is amplified by the signal amplification circuit and then transmitted to the main circuit board. The light shield outside the photoelectric detection component and the rubber sealing ring at the opening end isolate external light interference.

[0050] Finally, the circuit board processes the amplified electrical signal, combines it with the spectral characteristics of the neon lamp model to convert the electrical signal into a brightness value, and simultaneously records parameters such as power supply voltage and test distance. Finally, the brightness result and test conditions are output through the display screen. During the test, the anti-slip pads on the bottom of the test body prevent the instrument from sliding, and the heat dissipation holes on the side of the housing ensure continuous heat dissipation of the circuit board.

[0051] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description.
