Description

Technical Field

[0001] The present invention relates to the technical field of lighting fixtures, and in particular to a lighting fixture for preventing students from myopia and a method of using the lighting fixture. Background Art

[0002] Myopia is a common disease with a high incidence and a low incidence rate. Excessive eye use and visual fatigue are important factors leading to myopia in adolescents, and poor lighting environments are more likely to cause visual fatigue. Among them, high school is a very important period in a student's career, so high school students are under heavy academic pressure. Many high school students may study late into the night. Therefore, every high school student's desk is equipped with a corresponding desk lamp for study. Existing desk lamps have a lamp body, a lamp pole and a lamp base. The desk lamp is placed on the desk and is located in front of the user. The light is generally irradiated from the front to the desk for the user to use. However, the light irradiation range of existing desk lamps is relatively small and concentrated, and the light range remains unchanged. When the light irradiation position of the desk lamp needs to be adjusted, it is usually adjusted by moving the desk lamp or bending the lamp pole, which is inconvenient to use. Moreover, there is generally a distance between the lamp body of the desk lamp and the user's head, and the light is generally irradiated from the front to the desk. Therefore, when the user is studying at the desk, the head will unconsciously move forward to get close to the book, which easily fatigues the eyes. The user will inevitably develop a hunchback and myopia if he reads in an unfavorable posture for a long time.

[0003] In view of this, the present inventor has focused on the numerous deficiencies and inconveniences caused by the imperfections in the structure and usage of the aforementioned lighting fixtures, and has actively researched, improved, and trial-produced the present invention.

[0037] See also Figures 1 to 13 The present invention discloses a lighting fixture for preventing students from myopia, the lighting fixture includes a lamp body 10, a lamp pole 20 and a lamp holder 30, the lamp body 10 has two side lamp parts 1 and a middle lamp part 2 movably and slidably arranged between the two side lamp parts 1; the side lamp part 1 has a first lampshade 11 and a first light bar 12 located in the first lampshade 11, the first lampshade 11 has a first top side plate 111, a first bottom side plate 112, a first outer side plate 113, a first inner side plate 114 and two first end plates; The middle lamp portion 2 has a second lampshade 21 and a second light bar 22 located in the second lampshade 21. The second lampshade 21 has a second top side panel 211, a second bottom side panel 212, two second side panels 213 and two second end panels. The two first inner side panels 114 are respectively attached to the outer sides of the two second side panels 213, and the two first inner side panels 114 and the two second side panels 213 are light-transmitting panels. The inner sides of the first outer side panel 113, the two first end panels and the two second end panels are respectively coated with a reflective layer. The lamp body 10 also includes a top folded reflective portion 3 and two side folded reflective portions 4; the top folded reflective portion 3 is arranged on the lamp pole 20 and is located above the end of the middle lamp portion 2 close to the lamp pole 20, the top folded reflective portion 3 has a first folded reflective cloth 31 and a first folded storage groove 32, a first spiral spring 33 is provided in the first folded storage groove 32, one side of the first folded reflective cloth 31 is connected to the first coil spring 33, and the other side of the first folded reflective cloth 31 is fixed to the first coil spring 33. The two top side panels 211 are close to one end of the lamp pole 20; the two side folded reflective parts 4 are respectively arranged on the end surface of the side lamp parts 1 on both sides away from the lamp pole 20, and the side folded reflective parts 4 have a second folded reflective cloth 41 and a second folded storage groove 42, and a second spiral spring 43 is provided in the second folded storage groove 42. One side of the second folded reflective cloth 41 is connected to the second coil spring 43, and the other side of the second folded reflective cloth 41 is fixed to the end of the second side panel 213 away from the lamp pole 20.

[0038] The lamp portion of the lighting fixture for preventing students from myopia of the present invention comprises two side lamp portions 1 and a middle lamp portion 2 which can slide with each other, so that the lamp portion has a folded state and an unfolded state, which is simple to operate, convenient to use, and provides sufficient light. When folded for use, when the middle lamp portion 2 slides and folds between the two side lamp portions 1, the first folded reflective cloth 31 is automatically rolled up into the first folding storage groove 32 by the elastic force of the first coil spring 33, and the second folded reflective cloth 41 is automatically rolled up into the second folding storage groove 42 by the elastic force of the second coil spring 43. The two side lamp portions 1 and the middle lamp portion 2 are combined together, and since the first inner side panels 114 of the two side lamp portions 1 and the two second side panels 213 of the middle lamp portion 2 are translucent panels, the first bottom side panel 112 and the second bottom side panel 2 12 is a light-transmitting structure, and the two first outer panels 113, the two first end panels, the two second end panels, the two first top side panels 111 and the second top side panels 211 form a reflector; the light of the side lamp portion 1 and the middle lamp portion 2 can pass through the first inner panel 114 and the second side panel 213, so that part of the light is directly emitted from the first bottom side panel 112 and the second bottom side panel 212, and part of the light passes through or does not pass through the first inner panel 114 and the second side panel 213 and is reflected and emitted through the first outer panel 113, the two first end panels, the two second end panels, and the first folded reflective cloth 31, thereby improving the light utilization rate of the lighting fixture and providing sufficient light; when unfolded and used, the middle lamp portion 2 slides outward and extends out of the side lamp portions 1 on both sides, and the middle lamp portion 2 slides outward and then pulls the second side panel 112 and the second side panel 213. A folded reflective cloth 31 covers the top of the gap between the two side light parts 1, and the middle light part 2 slides outward to pull the second folded reflective cloth 41 against the outer sides of the two second side panels 213 of the middle light part 2; the two first outer panels 113 of the first lampshade 11, the two first end panels, the two first top side panels 111 and the first folded reflective cloth 31 form a reflector for the two first light strips 12. The first folded reflective cloth 31 can prevent the light of the two side light parts 1 from leaking out from the top of the gap between the two side light parts 1. The light of the first light strip 12 is all emitted from below, thereby improving the light utilization rate of the lighting fixture and providing sufficient light. The second folded reflective cloth 41 is affixed to the two sides of the middle light part 2 and can serve as a reflector. The two second ends of the second lampshade 21 The panel, the second top side panel 211 and the two second folded reflective cloths 41 form a reflector for the second light bar 22. The light from the middle light unit 2 passes through the second side panel 213 and is reflected by the second folded reflective cloth 41 and emitted from the second bottom side panel 212, thereby improving the light utilization rate of the lighting fixture and providing sufficient light. The outward expansion of the middle light unit 2 can not only increase the light irradiation range, but also reduce the distance between the lamp body 10 and the user's head, which can prevent the user's head from lowering lower, reduce eye fatigue, effectively correct bad sitting posture and prevent myopia. When the first folded reflective cloth 31 of the top folded reflective portion 3 is expanded, the first folded reflective cloth 31 slides out of the first folded storage slot 32 along with the middle light unit 2.During the rewinding operation of the first folded reflective sheet 31, after the force for pulling out the first folded reflective sheet 31 is removed, the first folded reflective sheet 31 is automatically retracted into the first folded storage slot 32 by virtue of the elastic force of the first coil spring 33.
