Description

Technical Field

[0001] The utility model relates to the technical field of classroom lamps, in particular to a classroom lamp assembly and a classroom lamp system with a stable light environment. Background Art

[0002] The classroom lamp is an LED eye-protection classroom lamp. It is a lighting system that is efficient, comfortable, safe, economical, beneficial to the environment, and improves the quality of teachers' work and students' study and life, as well as the physical and mental health of teachers and students, and embodies modern civilization. Green lighting aims to save energy, protect the environment, and improve the lighting quality of schools. A stable light environment in the classroom helps protect students' eyesight, so how to build a stable and uniform light environment in the classroom is crucial in lighting design.

[0003] Existing classroom lights generally adopt a 9+3 or 12+3 mode combination, and each light is relatively independent, so that each change will affect the light environment, making the light environment in the classroom easily unstable. Utility Model Content

[0004] In view of the above problems, the present invention aims to solve the above problems. One object of the present invention is to provide a classroom lamp assembly that solves the above problems, so that multiple classroom lamps can be linked and stabilized, and the lamps are not easily affected, so that the light environment is stable and uniform.

[0005] The solution adopted in this embodiment is to connect a row of lights into one, and at the same time change the stress point of the light board to eliminate the impact of the environment on the lamp. The following technical solutions are specifically adopted to solve these problems:

[0006] We have designed a classroom lamp assembly, including a long strip fixing frame, on which a plurality of light source lamp modules are arranged at intervals along the length direction, so that the plurality of light source lamp modules are located in the same straight line and connected as a whole; the long strip fixing frame is fixedly connected to the ceiling by setting a suspension rod. The long strip fixing frame is used to limit and fix a plurality of lamps to improve the overall stability.

[0007] Based on the different functional requirements of different schools for classroom lamps, a functional module is arranged between two adjacent light source lamp modules, and the functional module is detachably connected to the long strip fixing frame.

[0008] The optional functions provided include but are not limited to the following points: the functional module includes a combination of one or more of a sound-absorbing cotton module, an audio module, a germicidal lamp module, a health monitoring module, a human body sensing module, and a light sensing module.

[0009] In order to facilitate the installation and subsequent maintenance of the lamp and improve the stress on the lamp panel, the elongated fixing frame includes limiting ribs on both sides, a supporting portion at the lower edge of the limiting ribs, the supporting portion extending inward, and the frame of the light source lamp module placed on the upper side of the supporting portion.

[0010] Furthermore, in order to facilitate the installation of the long strip fixing frame on the ceiling in conjunction with the hanging rod, a limiting slot is provided at the top of the limiting rib, a connecting beam is provided at the lower end of the hanging rod, and clamping parts are provided at both ends of the connecting beam. The clamping parts are clamped with the limiting slots on both sides, and the hanging rod and the connecting beam are detachably connected by a pin.

[0011] In order to improve the stability and safety of the lamp, an optional solution is also provided: the classroom lamp assembly also includes an elastic pressure piece, an abutment portion is provided on the inner side of the upper end of the limiting rib, one end of the elastic pressure piece abuts against the abutment portion, and the other end abuts against the light source lamp module.

[0012] In order to connect the two limiting ribs into one, an end cover is also included. The limiting rib is provided with a limiting portion on one side of the supporting portion. When installed, the side wall of the light source lamp module abuts against the limiting portion. The end cover is threadedly connected to the abutting portion and the limiting portion respectively by screws.

[0013] In addition, for schools with low functional requirements, an optional functional module is provided, which includes a light guide plate, which is directly installed between the two light source lamp modules, or a further optional solution is: the light source lamp module is provided with a groove near the end of the light guide plate, so that the light guide plate and the light source lamp module are optically conductive.

[0014] Based on the above-mentioned classroom lamp assembly, a solution is provided for the overall lighting of the classroom. This solution uses the above-mentioned classroom lamp assembly to form a classroom lamp system with a stable light environment, including classroom lamp assemblies arranged along the length direction of the blackboard, wherein the light source lamp module is a blackboard lamp; and also includes several rows of classroom lamp assemblies arranged in parallel in the classroom, and the spacing between each row of classroom lamp assemblies is equal.

[0015] In order to more conveniently adjust the lighting environment of the entire classroom, the light source lamp module can be slidably arranged along the length direction of the long strip fixing frame to adjust the distance between two adjacent light source lamp modules.

[0016] Compared with the prior art, the classroom lamp assembly of the utility model has the following technical effects:

[0017] A plurality of light source lamp modules are installed using a long strip fixing frame so that the plurality of light source lamp modules are located in the same straight line and connected as a whole, thereby ensuring that the illumination angles of the plurality of lamps remain consistent and the illumination uniformity of the light environment is higher, while effectively reducing the shaking of the lamps and making the light environment more stable.

[0018] The long strip fixing frame is fixedly connected to the ceiling by setting a hanging rod, and the frame of the light source lamp module is placed on the supporting part of the long strip fixing frame. The stress points are concentrated on the long strip fixing frame, and the installation is more stable and firm. At the same time, the stress points of the light source lamp module are distributed on the outer frame, so that the light strip is no longer stressed, which effectively increases the life of the light strip. At the same time, it reduces the impact of the light environment caused by the shaking of the lamp directly transmitted to the deformation of the light strip, making the light environment more stable.

[0019] A functional module is arranged between two adjacent light source lamp modules, and the functional module is detachably connected to the long strip fixing frame. Installing the functional module between the light source lamp modules can meet various needs of the school. At the same time, the standard size of the functional module makes the spacing between the two light source lamp modules uniform after installation, and the illumination uniformity of the light environment is higher.

[0033] In order to make the purpose, technical scheme and advantages of the embodiments of the present invention clearer, the technical scheme in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments in the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention. It should be noted that the embodiments in this application and the features in the embodiments can be combined with each other arbitrarily without conflict.

[0034] The classroom lamp assembly and the classroom lamp system with a stable light environment are described in detail below in conjunction with the accompanying drawings and embodiments. Example

[0035] This embodiment is the most basic configuration, and the functional module 3 only selects the sound-absorbing cotton module 31.

[0036] like Figure 5 , Fig. 9As shown, the classroom lamp assembly in this embodiment includes a long strip fixing frame 1, and the long strip fixing frame 1 is provided with a plurality of light source lamp modules 2 at intervals along the length direction, so that the plurality of light source lamp modules 2 are located in the same straight line and connected as a whole. Figure 1 or Figure 2 , a plurality of light source lamp modules are limited and fixed by a long strip fixing frame 1 to improve the overall stability. In this embodiment, the light source lamp module takes a long strip classroom lamp 22 as an example. This embodiment adopts the preferred technical solution, and the length direction of the classroom lamp 22 is consistent with the length direction of the long strip fixing frame 1. It should be noted that the technical solution that the length direction of the classroom lamp 22 is perpendicular to the length direction of the long strip fixing frame 1 also falls within the protection scope of this patent. According to the size of the classroom, 3 or 4 classroom lamps 22 can be selected to be connected to a long strip fixing frame 1. When multiple classroom lamps 22 are connected to the long strip fixing frame 1, their illumination angles will remain consistent, and the light source can also better keep parallel with the long strip fixing frame 1 and the classroom wall, making the lighting environment more uniform.

[0037] In order to facilitate the installation and subsequent maintenance of the lamps and to improve the stress of the lamp panels, such as Figure 4 As shown, the long strip fixing frame 1 is fixedly connected to the ceiling by setting a suspension rod 4, and the long strip fixing frame 1 includes limiting ribs 14 located on both sides, and the limiting ribs 14 are hollow, and the two limiting ribs 14 are connected as a whole through end covers 15 at both ends. The lower edge of the limiting rib 14 is a supporting portion 11, and the supporting portion 11 extends inward, and the frame of the light source lamp module 2 is placed on the upper side of the supporting portion 11. In order to connect the two limiting ribs 14 as a whole, it also includes an end cover 15, and the limiting rib 14 is provided with a limiting portion 16 on one side of the supporting portion. When installed, the side wall of the light source lamp module abuts against the limiting portion 16, and the end cover 15 is threadedly connected to the abutting portion and the limiting portion 16 respectively by screws. The limiting portion 16 can limit the left and right sides of the light source lamp module 2 after installation, and the position is accurate and the stability is good after installation. After the end cap 15 is installed, the whole structure is more beautiful. At the same time, the combination of the end cap 15 and the connecting crossbeam 41 makes the connection between the two limiting ribs 14 stable. The light source lamp module 2 is installed from top to bottom and is directly placed on the supporting part 11. The light is irradiated downward from the hollow area between the two limiting ribs 14, which is very convenient for installation and later maintenance. Traditional lamps are generally provided with two connecting seats on the lamp housing to connect with the suspension rod 4. When the lamp is subjected to force, it will first be transmitted to the light bar, causing the light bar to deform and change the irradiation angle, making the light environment easy to change. In this embodiment, the suspension rod 4 is connected to the long strip fixing frame 1, and the force points are all on the long strip fixing frame 1, and the edge of the classroom lamp 22 is in contact with the supporting part 11. When the entire long strip fixing frame 1 is subjected to force, it will not affect the light bar in the classroom lamp 22, and the light environment will not change, so that the overall light environment remains stable.

[0038] like Figure 4 As shown, further, in order to facilitate the installation of the long strip fixing frame 1 on the ceiling with the hanging rod 4, a limiting slot 12 is provided at the top of the limiting rib 14, a connecting beam 41 is provided at the lower end of the hanging rod 4, and a clamping portion 42 is provided at both ends of the connecting beam 41. The clamping portion 42 is clamped with the limiting slot 12 on both sides, and the hanging rod 4 and the connecting beam 41 are detachably connected by a latch. Figure 1 or Figure 2 In this embodiment, five suspension rods 4 are connected to the long strip fixing frame 1 at the same time. The connection points are located on both sides of the long strip fixing frame 1 through the connecting beam 41. Ears 43 are provided on the connecting beam 41. When the connecting beam 41 is inserted into the limiting slot 12, the ear 43 can be bent to lock the connecting beam 41 and the limiting slot 12.

[0039] Since the space between the limiting ribs 14 is hollow, Figure 5 As shown, a sound-absorbing cotton module 31 can be optionally provided between two adjacent light source lamp modules 2, and the sound-absorbing cotton module 31 is detachably connected to the long strip fixing frame 1. This makes the lamp more beautiful as a whole. The light source lamp module 2 and the functional module 2 are both provided with a frame wrapping on the outside, and can be independently installed on the long strip fixing frame 1. The light source lamp module 2 and the functional module 2 are both electrically connected to the control center. At the same time, due to the setting of the sound-absorbing cotton module 31, the sound waves generated by the loudspeaker can be absorbed. When the sound is transmitted to the classroom lamp assembly, the vibration of the sound wave will cause the lamp to fluctuate at a certain frequency. After the sound-absorbing cotton module 31 is provided, most of the sound waves can be absorbed, so that the influence of the loudspeaker on the classroom lamp 22 is reduced, the stability of the lamp is ensured, and the light environment is more stable. Example

[0040] In this embodiment, the functional module 3 selects a combination of a sound-absorbing cotton module 31 and an audio module 32, and the rest is the same as in the first embodiment.

[0041] like Figure 2 As shown, a sound-absorbing cotton module 31 and an audio module 32 are selected to be set between two adjacent light source lamp modules 2. The sound-absorbing cotton module 31 and the audio module 32 are set in series, and the sum of the lengths of the sound-absorbing cotton module 31 and the audio module 32 is the required spacing between the two light source lamp modules 2. An audio module 32 is set next to each classroom lamp 22 so that the sound of the teacher's lecture can be transmitted to every place in the classroom. When the audio module 32 occurs, it will generate downward sound waves and part of the sound waves acting on the lamp. The sound-absorbing cotton module 31 can absorb this part of the sound waves, so that the impact of the sound waves on the lamp is reduced, so that the light environment can still remain stable when the audio module 32 is used. Example

[0042] In this embodiment, the functional module 3 selects a combination of a human body sensing module 34, a light sensing module 35 and a sound-absorbing cotton module 31, and the rest is the same as the first embodiment.

[0043] like Figure 3 As shown, this embodiment selects to set a human body sensing module 34, a light sensing module 35 and a sound-absorbing cotton module 31 between two adjacent light source lamp modules 2. The human body sensing module 34 and the light sensing module 35 are set on the same side of the sound-absorbing cotton module 31. At the same time, the human body sensing module 34 and the light sensing module 35 are connected to the control center of the lamp. The human body sensing module 34 can automatically turn on the classroom light 22 when detecting a human body, and automatically turn off the light when detecting that there is no one in the classroom, so as to achieve energy saving and emission reduction. When the light sensing module 35 detects the light intensity of the environment, it transmits data to the control center. When the ambient brightness is low in the morning, the classroom light 22 is controlled to turn on with increased brightness, and when the ambient light is strong, the brightness can be appropriately reduced, so as to achieve intelligent control and effectively save energy. Example

[0044] In this embodiment, the functional module 3 selects a combination of a sound-absorbing cotton module 31, a germicidal lamp module 33, a health monitoring module 37 and a human body sensing module 34, and the rest is the same as in the first embodiment.

[0045] refer to Figure 1 , choose to set a sound-absorbing cotton module 31, a human body sensing module 34 and a germicidal lamp module 33 between two adjacent light source lamp modules 2, and the sum of the lengths of the three is the required spacing between the two light source lamp modules 2. Preferably, the germicidal lamp module 33 and the human body sensing module 34 are set on both sides of the sound-absorbing cotton module 31. The human body sensing module 34 monitors whether there is someone, and the light can be turned on when someone leaves. At the same time, after the human body sensing module 34 detects that there is no one in the classroom, the germicidal lamp module 33 is turned on at night to sterilize the classroom. At the same time, the sound-absorbing cotton module 31 can absorb the sound waves of the loudspeaker, so that the impact of the sound waves on the lamps is reduced, so that the light environment can still remain stable. The health monitoring module 37 can monitor students' body temperature and other physiological data, and judge the students' health status in time. When it is detected that there is a problem with the students' health status, the control center will promptly notify the teacher. At the same time, the germicidal lamp module 33 is controlled at night to sterilize the classroom, ensuring that the classroom has a healthy environment. Example

[0046] Compared with the first embodiment, this embodiment further includes an elastic pressing member 5, and the rest is the same as the first embodiment.

[0047] The classroom lamp assembly also includes an elastic pressing member 5, such as Figure 6As shown, the inner side of the upper end of the limiting rib 14 is provided with an abutment portion 13, one end of the elastic pressing piece 5 abuts against the abutment portion 13, and the other end abuts against the light source lamp module 2. For the convenience of installation and later maintenance, the light source lamp module 2 and the function module 3 are directly overlapped on the abutment portion 13. When the student jumps up to touch it, there is a certain probability that the light source lamp module 2 or the function module 3 will fall and hit the student. In this embodiment, a plastic elastic pressing piece 5 is used. The elastic pressing piece 5 is installed on the light source lamp module 2 and the function module 3 respectively, and a downward squeezing force is generated thereon. When the student jumps up to touch the lamp, the force is absorbed by the elastic pressing piece 5, making the lamp more stable and safe. At the same time, the elastic pressing piece 5 has a certain elastic plasticity. When the lamp is subjected to external forces such as fans or air conditioning wind, it helps to reduce the amplitude of the light source lamp module 2, so that the light source remains stable, and the light environment always remains stable. Example

[0048] In this embodiment, the functional module 3 is configured as a light guide plate 36 , and the rest is the same as that of the first embodiment.

[0049] For some schools, this embodiment also provides an optional solution for a functional module 3, such as Figure 7 As shown, the functional module 3 includes a light guide plate 36, and the light guide plate 36 is directly installed between the two light source lamp modules 2. Since the space between the limiting ribs 14 is hollow, and some schools do not have the need to increase functions, the lamp retains the hollow area between the limiting ribs 14, which is not aesthetically pleasing. The addition of the light guide plate 36 can not only make the classroom lamp assembly more beautiful, but also the setting of the light guide plate 36 can reflect the light to a certain extent, making the classroom lamp 22 light look brighter and making the overall light environment better. Both sides of the light guide plate 36 can transmit light, and the light below can pass through the light guide plate 36 to the ceiling, so that the amount of light passing upward is increased, and the overall brightness of the classroom is increased. Example

[0050] In this embodiment, the functional module 3 is configured as a light guide plate 36 , but the installation method of the light guide plate 36 is further optimized, and the rest is the same as that of the fifth embodiment.

[0051] Further options are: Figure 8 As shown, the end of the light source lamp module 2 near the light guide plate 36 is provided with a slot 23, so that the light guide plate 36 is in optical communication with the light source lamp module 2. Increasing the thickness of the light guide plate 36 allows more lateral light to enter the light guide plate 36, thereby increasing the overall brightness of the light guide plate 36, and increasing the amount of light passing from top to bottom, making the overall appearance brighter. Example

[0052] This embodiment is an overall solution for classrooms, taking the original 9+3 classroom as an example.

[0053] Traditional small classrooms generally use a combination of 9 classroom lights and 3 blackboard lights. Since the illumination angle of each lamp cannot be adjusted to be consistent, slight alternation between light and dark is prone to occur, making the overall illumination uniformity not high enough. At the same time, a single lamp is easily affected by fans and air-conditioning wind and shakes, making the overall stability low. The shaking frequency of each lamp is also different, and the light environment will undergo complex changes. This change can easily lead to visual fatigue and affect students' eyesight.

[0054] like Fig. 9 As shown, in this embodiment, the above-mentioned classroom lamp assembly is used to form a classroom lamp system with a stable light environment, including a classroom lamp assembly arranged along the length direction of the blackboard, wherein the light source lamp module 2 is a blackboard lamp 21; and also includes several rows of classroom lamp assemblies arranged in parallel in the classroom, and the spacing between each row of classroom lamp assemblies is equal. The three blackboard lamps 21 are connected as one by a long strip fixing frame, so that the three classroom lamps 22 can be evenly irradiated to the blackboard surface, effectively improving the uniformity of illumination of the blackboard surface. In this embodiment, the classroom lamp 22 is installed in a direction perpendicular to the blackboard. It should be noted that the installation method of the classroom lamp 22 parallel to the blackboard lamp 21 also belongs to the protection scope of this patent. The three classroom lamps 22 in the same row are connected as one by a long strip fixing frame 1, and a total of three rows are set. Since the length of the long strip fixing frame 1 is large, it is easy to control the three long strip fixing frames 1 to be parallel to each other during installation, so that the overall illumination is more uniform. The three classroom lamps 22 in the same row have the same irradiation angle, and the three rows of lamps make the illumination in the classroom uniform, and there is no alternation of light and dark. At the same time, since the long strip fixing frame 1 is connected by a plurality of suspension rods, the overall stability is higher and it is less likely to shake due to environmental influences, so that the light environment is more stable, visual fatigue is reduced, and students' eyesight is effectively protected. Example

[0055] In order to more conveniently adjust the light environment of the entire classroom, the light source lamp module 2 can be slidably arranged along the length direction of the long strip fixing frame 1 to adjust the distance between two adjacent light source lamp modules 2. When the length of the classroom is large, but four classroom lamps 22 cannot be installed, the distance between the light source lamp modules 2 can be adjusted, and the distance between the two light source lamp modules 2 can be increased to make the irradiation range larger, so that the overall light environment is uniform when the illumination meets the requirements, and there will be no dark areas.
