The terminology used in the description of the present application herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the application. As used herein, the term "and/or" includes any and all combinations of one or more of the associated listed items.
In order to ensure the safety of teachers and students, ultraviolet disinfection lamps are generally arranged in classrooms. The ultraviolet disinfection lamp generally adopts an ultraviolet quartz glass lamp tube with strong radiation capability and the wavelength of 253.7 nM.
For example, the following two forms of sterilizing lamps:
1. the electroplated iron sheet support lamp is directly provided with a 36-watt ultraviolet lamp tube, but when the peripheral lighting lamp is in practical application, the lighting lamp is irradiated by the ultraviolet lamp for a long time, the lighting light source is yellowed, and the corresponding function can be lost.
2. The size of a base plate of the classroom lamp is unchanged, a grid space is separated behind an electroplating grid, or the grid is cut short, and one end of the grid is provided with a low-power ultraviolet lamp of 3-9W, so that the overall harmony and the cost of the grid have certain advantages, but the power of the ultraviolet lamp is small, and the disinfection effect is poor.
In order to avoid the increase of the disinfection effect of the illuminating lamp when the illuminating lamp is irradiated by ultraviolet rays, as shown in fig. 1 to 3, the illuminating lamp and the ultraviolet lamp are connected through the shell in the prior art, and the distance between the illuminating light source 10 and the ultraviolet light source 20 is almost set to be zero. When the ultraviolet light source 20 is operated, the ultraviolet light is blocked by the outer shell outside the illumination light source 10, and the blocked angle is almost 90 degrees, so that the problem that the sterilization blind area is large and the sterilization effect is not ideal exists.
In order to solve the problem, as shown in fig. 4 to 7, the application provides a classroom lighting device including a lighting source 10 and an ultraviolet light source 20, a lamp housing 11 is configured at the periphery of the lighting source 10, and a bottom surface of the lamp housing 11 in a use state is a light exit surface 12 arranged horizontally;
the bottom side of the ultraviolet light source 20 is 0-10 mm higher than the light-emitting surface 12, and the horizontal distance between the center of the ultraviolet light source 20 and the corresponding side edge of the lamp housing 11 is 40-80 mm;
at least one part of the area is a disinfection blind area 30 right below the light-emitting surface 12, the projection light of the ultraviolet light source 20 towards the disinfection blind area 30 is blocked by the lamp housing 11, the connecting line between any point in the disinfection blind area 30 and the edge of the lamp housing 11 is a reference line 31, and the included angle between the reference line 31 and the light-emitting surface 12 is less than or equal to 24 degrees.
The usage status referred to in this application is a status when the illumination light source 10 is working, β shown in fig. 5 to 7 is an included angle between the reference line 31 and the light emitting surface 12, and E in fig. 6 is a height difference between the bottom side of the ultraviolet light source 20 and the light emitting surface 12.
In this embodiment, the lamp housing 11 is made of aluminum, the illumination light source 10 is made of cold-rolled sheet, the ultraviolet light source 20 is disposed below the aluminum profile bracket, the end caps at both ends are black ultraviolet-resistant PC, and the lamp holder is black ultraviolet-resistant PC.
When the ultraviolet light source 20 is approximately a light emitting point, a connecting line between any point in the dead sterilization zone 30 and the edge of the lamp housing 11 is a reference line 31, and an included angle β between the reference line 31 and the light emitting surface 12 is less than or equal to 24 degrees.
When the space volume of the ultraviolet light source 20 is considered, as shown in fig. 5, which is a schematic cross-sectional view of the disinfection dead zone 30 generated when the ultraviolet light source 20 operates, the disinfection dead zone 30 can be understood that even if any point on the ultraviolet light source 20 projects light in all directions, the light projected by all the light source points is blocked by the lamp housing 11 and cannot be projected directly to the disinfection dead zone 30.
For example, the top end reference line 31a and the bottom end reference line 31B of the ultraviolet light source 20 in fig. 5 divide the area a, the area B, and the area C below the illumination light source 10.
In the area A, any light source point of the ultraviolet light source 20 can project light rays to the area, and the area A is not regarded as a disinfection blind area 30;
in the area B, the light source point at the top of the uv light source 20 cannot directly project light to the area, but the light source point at the bottom of the uv light source 20 can project light to the area, so the area B is not regarded as the disinfection dead zone 30;
in the area C, all light source points on the uv light source 20 cannot directly project light to the area, so only the area C is regarded as the disinfection dead zone 30.
Therefore, it can be seen from the above analysis that the magnitude of the disinfection shadow zone 30 has a large relationship with the height position of the bottom of the ultraviolet light source 20 (i.e., the extending direction of the bottom end reference line 31 b).
In one embodiment, in order to minimize the area of the disinfection shadow 30, the uv light source 20 includes a first uv light source and a second uv light source, which are disposed at two opposite sides of the horizontal direction of the lamp housing 11. The problem of uneven distribution of the disinfection area during irradiation can be avoided. As shown in fig. 4, the light emitting surface 12 is rectangular, and the illumination source 10 is a first strip-shaped lamp 13 arranged along the length direction of the light emitting surface 12; the first ultraviolet light source and the second ultraviolet light source are arranged at two opposite sides of the lamp housing 11 in the width direction of the light-emitting surface 12.
The first strip-shaped lamp 13 can increase the light source area and ensure the lighting effect in the classroom, and the form and the arrangement direction of the ultraviolet light source 20 also influence the distribution of the disinfection blind area 30 to a certain extent.
For example, the first ultraviolet light source and the second ultraviolet light source are both the second strip-shaped lamp 21 arranged along the length direction of the light-emitting surface 12, and the length of the first strip-shaped lamp 13 is equal to that of the second strip-shaped lamp 21. In order to distribute the disinfection dead zones 30 as evenly as possible, the first ultraviolet light source and the second ultraviolet light source are aligned relatively along the length direction of the light emitting surface 12 and are arranged at equal heights.
In an embodiment, the first ultraviolet light source and the second ultraviolet light source are both the second strip-shaped lamp 21 arranged along the length direction of the light emitting surface 12, and the length of the first strip-shaped lamp 13 and the length of the second strip-shaped lamp 21 can be selected as required. When a more effective disinfection block is needed, the lamp tube can be set to be 36W 1.2 m, and if no other requirement exists, the lamp tube is generally defaulted to be 18W 0.6 m.
The ultraviolet light source 20 and the illumination light source 10 can also utilize related structures of the prior art in terms of the two, and because the two are close to each other, no matter mechanical parts or circuit arrangement, some structures can be integrated, such as a common mounting connection structure, a common part of driving circuit and the like, and can be configured independently, thereby being more convenient for flexible adjustment and arrangement.
As a classroom lamp, multiple hangers are installed on the ceiling, in one embodiment, the uv light source 20 and the illumination light source 10 share the same hanger 40, and the hanger 40 includes:
a boom 401;
the connection frame 402 is fixed to the bottom end of the suspension rod 401, and the illumination light source 10 and the ultraviolet light source 20 are both fixedly attached to the connection frame 402.
The top surface of the linking frame 402 has tabs 41, the tabs 41 being arranged in pairs and extending upwardly, and the bottom of the hanger bar 401 being located between the tabs 41 and connected to the linking frame 402 by a latch.
In other embodiments, as shown in fig. 7, the ultraviolet light source 20 and the illumination light source 10 are independently provided with a hanger 40. During specific installation, the ultraviolet light source 20 and the illumination light source 10 can be directly provided with different lengths of the suspender 401 to realize the height difference, and if no disinfection requirement exists, the independent support lamp can be quickly installed on the hoisting frame 40 used by the ultraviolet light source 20, so that the independent support lamp can meet various requirements.
Along the width direction of the light emitting surface 12, the middle portion of the connection frame 402 is fixed to the lamp housing 11, and the first ultraviolet light source and the second ultraviolet light source are respectively fixed to two sides of the connection frame 402 through the respective matched housings.
In one embodiment, the second strip-shaped lamp 21 has a circular cross section and a diameter D1, and the diameter D1 is 15-28 mm.
As shown in fig. 5, although the region B can also be sterilized and disinfected, only a part of the uv light source 20 can be projected to the region, when the diameter D1 is increased, the included angle between the top reference line 31a projected by the uv light source 20 and the light emitting surface 12 is increased, and at this time, the area of the region B is also increased, and the energy radiation, i.e., the disinfection effect in the unit space is weakened, therefore, when the other conditions are not changed, the size D1 is preferably reduced.
In one embodiment, the center of the UV light source 20 is horizontally spaced from the corresponding side edge of the lamp envelope 11 by a distance W1; the width of the light emitting surface 12 is W2; the ratio of W1 to W2 is 1:3 to 6.
The ratio of W1 to W2 affects the direction of extension of the bottom reference line 31b and the overall size of the classroom lighting equipment, and the appropriate ratio can achieve both compactness of the equipment and distribution of the disinfection shadow zones 30, thereby achieving better expected effects.
In this embodiment and the cross-sectional view are examples, when W2 is 295mm, and β is 24 degrees, it is preferable that W1 is 60mm, and E is 1.5 mm. The shadow area of the sterilizing dead zone 30 shown in FIG. 6 is set to S1, and the height H1 thereof can be set according to
H1 is calculated to be about 65 mm;
at this time
Comparing with the prior art in fig. 3, the shadow area of the disinfection dead zone 30 is S2, where W2 is 295mm, H2 is the distance from the light-emitting surface 12 to the ground, and where S2 is W2 × H2, 619000mm2；
Therefore, the classroom lighting equipment not only can protect the lighting source 10, but also has a wider disinfection range, a better sterilization effect and lower energy consumption per unit area.
The technical features of the above embodiments can be arbitrarily combined, and for the sake of brevity, all possible combinations of the technical features in the above embodiments are not described, but should be considered as the scope of the present specification as long as there is no contradiction between the combinations of the technical features. When technical features in different embodiments are represented in the same drawing, it can be seen that the drawing also discloses a combination of the embodiments concerned.
The above examples only express several embodiments of the present application, and the description thereof is more specific and detailed, but not construed as limiting the claims. It should be noted that, for a person skilled in the art, several variations and modifications can be made without departing from the concept of the present application, which falls within the scope of protection of the present application.
