[0028] As shown in the figure, a technical scheme provided by the utility model comprises: Figure 2 、 Figure 4 and Figure 5 ​As shown, the mounting seat 3 and the lampshade 4 are provided with a protection mechanism, which comprises a protective cover 14, the protective cover 14 is movably installed on both sides of the lampshade 4, a top frame 15 is fixedly installed on the top end of the lampshade 4, the top end of the protective cover 14 is movably connected to the inner side of the middle part of the top frame 15 through a connecting rod 16, the inner side of the bottom of the protective cover 14 is movably connected to the outer side of the mounting seat 3 through a rotating shaft, a driving mechanism cooperating with the protection mechanism is arranged in the inner side of the stand 2, the driving mechanism comprises a motor 11, the motor 11 is fixedly installed on the inner side of the middle part of the stand 2, a lead screw 12 is fixedly installed on the output shaft end of the motor 11, a sleeve 13 threadedly connected with the lead screw 12 is fixedly installed on the middle bottom end of the lampshade 4, the motor 11 is electrically connected with the adapter plug-in end 9;

[0029] In this embodiment, when the device is not in use, the protective cover 14 will automatically close to cover the lampshade 4 and the light-transmitting cover plate 5, preventing dust from entering or external damage, while avoiding light leakage, reducing the interference to the surrounding environment, not only prolonging the service life of the device, but also reducing the maintenance cost, improving the durability and reliability of the equipment.

[0030] Working principle: when the device is in white backlight mode, the RGBW lamp tube 7 emits uniform white light, which irradiates the mountain-shaped logo 6 through the light-transmitting cover plate 5, the user observes the clarity of the mountain-shaped logo 6 to judge the vision condition, thereby completing the measurement of the vision degree, when the device is switched to red, green and blue three-color light mode, the RGBW controller 8 controls the RGBW lamp tube 7 to emit red, green and blue light in turn, the user needs to directly observe the display effect of the light-transmitting cover plate 5 under different color light, if the user cannot accurately distinguish one or more colors, it may indicate that he has color blindness. In addition, when the device is not in use, the protection mechanism will automatically start, the motor 11 drives the lead screw 12 to rotate, driving the sleeve 13 to move, so that the protective cover 14 is stably closed through the linkage action of the connecting rod 16 and the top frame 15, covering the lampshade 4 and the light-transmitting cover plate 5, preventing dust from entering or external damage.

[0031] It should be noted that the color switching function of the RGBW lamp tube 7 is based on the four LED chips of red (R), green (G), blue (B) and white (W) integrated inside, and the current intensity of each chip is adjusted by the RGBW controller 8 using the PWM (pulse width modulation) technology, so as to accurately control the brightness of them; when a specific color needs to be output, the RGBW controller 8 will adjust the brightness ratio of the red, green and blue chips according to the color requirement, for example, increase the brightness of the red chip and reduce the brightness of the green and blue chips, the lamp tube will present red, at the same time, increase the brightness of the red and green chips and reduce the brightness of the blue chip, the lamp tube will present yellow, and the white chip directly provides high-brightness pure white light without generating mixed white through red, green and blue, thereby avoiding the problem of inaccurate color temperature or insufficient brightness when mixed white.
