[0021] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0022] Example:

[0023] See also Figure 1-4 The present embodiment provides a pupil lamp suitable for children, including a lamp tube 1, a screw rod 14 is installed at one end of the lamp tube 1, a lamp group 16 is installed on the inner side of the screw rod 14, an adjustment mechanism 2 is installed at one end of the lamp tube 1, and the adjustment mechanism 2 includes a light-emitting tube 21, a threaded ring 24 and a sleeve 23. The light-emitting tube 21 and the threaded ring 24 are threadedly connected to the screw rod 14, an annular groove 17 is opened at one end of the screw rod 14, one end of the sleeve 23 is inserted into the inner side of the annular groove 17, the lamp group 16 is located on the inner side of the sleeve 23, and a lens 22 is embedded at one end of the light-emitting tube 21. The edge of one end of the sleeve 23 coincides with the edge of one side of the lens 22. The pupil lamp for children is used. When in use, the light emitted by the lamp group 16 is gathered on the inner side of the sleeve 23, and the sleeve 23 is used to emit the light source emitted by the lamp group 16 through the lens 22 on the light output tube 21 to illuminate the pupil range of the child patient. When it is necessary to adjust the size of the light source emitted by the lamp group 16, the light output tube 21 is rotated clockwise on the screw rod 14 to make the distance between the lens 22 and the lamp group 16 closer and closer. At this time, the size of the light source emitted is larger. Therefore, there is no need to bring the pupil lamp close to the pupil of the child patient. The illumination range of the light source can be magnified from a distance, which is convenient for checking the pupil condition of the child patient and avoids the situation where the pupil lamp is brought close to the child patient and causes the child patient to panic and refuse to cooperate.

[0024] In this embodiment, if Figure 1 and Figure 2 As shown, a collar clip 12 is installed on the side of one end of the lamp tube 1 away from the adjustment mechanism 2, and a display screen 13 is embedded on the collar clip 12. The display screen 13 is designed as a miniature size structure. The display screen 13 displays the percentage of the remaining power of the pupil lamp through a numerical value, so that the remaining power of the pupil lamp can be observed more intuitively.

[0025] In this embodiment, if Figure 2 As shown, a push switch 11 is installed on the outer surface of the lamp tube 1, and the lamp group 16 is composed of two lamp beads with a color temperature of 4000K and 5000K. When the push switch 11 is pushed forward, the lamp beads with a color temperature of 4000K are lit, and when the push switch 11 is pushed backward, the lamp beads with a color temperature of 5000K are lit. Therefore, it is convenient to adjust to different light source color temperatures in different usage scenarios to avoid strong light irradiating the pupils.

[0026] In this embodiment, if Figure 1 、 Figure 2 and Figure 4 As shown, a charging mechanism 3 is installed at the end of the lamp tube 1 away from the adjustment mechanism 2, and a base 31 is installed on the charging mechanism 3. An adhesive sticker 32 for sticking the base 31 on the desktop is installed at the bottom of the base 31, and a charging tube 33 is fixedly installed at the top center of the base 31. The charging mechanism 3 can be connected to a USB power interface. Two positive and negative charging pads are provided at the bottom inner side of the charging tube 33, and a slide is provided on the inner side surface of the charging tube 33. A slider with a size matching the slide is provided on the side surface of one end of the lamp tube 1, and two positive and negative charging electrode posts are provided on the inner side of the bottom of the lamp tube 1. After the bottom of the lamp tube 1 and the slider are inserted into the charging tube 33 and the inner side of the slide respectively, the electrode posts touch the charging pads on the inner side of the charging tube 33, so that charging can be conveniently performed. At the same time, when the pupil lamp is not in use, it is directly plugged into the charging tube 33 for charging to prevent insufficient power.

[0027] In this embodiment, if Figure 1 and Figure 2 As shown, a lamp post 15 is installed inside the screw rod 14, and the lamp group 16 is installed on the outer surface of the lamp post 15. The sleeve 23 is inserted into the inner side of the annular groove 17 and then sleeved on the outer ring surface of the lamp post 15. Therefore, when the lamp group 16 is lit, the light source is transmitted to the lens 22 through the sleeve 23 and emitted through the lens 22.

[0028] In this embodiment, if Figure 1 、 Figure 2 and Figure 3As shown, after the threaded ring 24 is threadedly connected to the screw rod 14, one end of the light emitting tube 21 is threadedly connected to the screw rod 14. After the threaded ring 24 and the light emitting tube 21 are tightened clockwise on the screw rod 14, they are spliced ​​together with the lamp tube 1. When the light emitting tube 21 is screwed to a suitable position, one end of the light emitting tube 21 is squeezed by screwing the threaded ring 24, so that the position of the light emitting tube 21 can be fixed to prevent it from rotating actively.

[0029] Working principle: When the children's pupil lamp is in use, the push switch 11 is pushed forward to light up the 4000K color temperature lamp bead, and the push switch 11 is pushed backward to light up the 5000K color temperature lamp bead. When the lamp group 16 is lit, the light source is transmitted to the lens 22 through the sleeve 23 and emitted through the lens 22 to illuminate the pupil range of the child patient. When the size of the light source emitted by the lamp group 16 needs to be adjusted, the distance between the lens 22 and the lamp group 16 is closer and closer by rotating the light tube 21 clockwise on the screw rod 14. At this time, the size of the light source is larger. , the smaller the light source illumination size is when the light tube 21 is rotated counterclockwise, so the light source illumination range can be magnified from a distance without bringing the pupil lamp close to the pupil of the child patient, making it convenient to check the pupil condition of the child patient and avoiding the situation where the child patient panics and refuses to cooperate by bringing the pupil lamp close to the child patient. At the same time, one end of the lamp tube 1 can be charged by inserting it into the charging tube 33. The display screen 13 will flash during charging, and the display screen 13 will go out when the power is fully charged, so that charging can be convenient. When the pupil lamp is not in use, it can be directly plugged into the charging tube 33 for charging to prevent insufficient power.

[0030] All technical features in this embodiment can be freely combined according to actual needs.

[0031] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the present invention can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention, which should be covered by the protection scope of the present invention.
