Description

TECHNICAL FIELD

[0001] The present application relates to a kind of soft light skylight, in particular a kind of skylight soft light system for building roof. BACKGROUND

[0002] In sports stadium, high-speed rail station and other large buildings, often need to install light-transmitting skylight on its building top, so that external natural light can be transmitted through light-transmitting skylight to illuminate the interior of the building, while ensuring the brightness of the room to achieve the effect of energy saving and environmental protection. In order to improve the installation stability and structural strength of the light-transmitting skylight, the light-transmitting skylight needs to be fixed by steel frame structure, so that the four edges of the light-transmitting glass can be fixed at the bottom of the steel frame structure, and the building roof is completely covered by using several small area light-transmitting glass to achieve the functions of waterproofing and light transmission. On the other hand, in order to avoid the crowd directly observing the steel frame structure from the inside of the room, the glass at the bottom of the steel frame structure will also use frosted glass, so that the frosted glass can shield the steel frame structure, and the light-transmitting skylight only has the function of light transmission, and the crowd cannot observe the steel frame structure through the frosted glass.

[0003] But the defect of this structure is that, since the steel frame structure needs to be set as a three-dimensional structure due to strength, i.e. a large number of columns and side connecting ribs are installed in the middle of the steel frame structure, so that when external natural light enters, part of the light will be transmitted through the steel frame structure and directly shine on the frosted glass, and another part of the light will be blocked by the steel frame structure, resulting in a shadow on the frosted glass. This makes the crowd in the room observe the light-transmitting skylight on the roof from below, and see a large number of disordered and mottled light and shadow, affecting the overall lighting effect and aesthetics of the light-transmitting skylight.

[0004] In addition, when natural light enters from the outside, it also causes the temperature in the room to rise, thereby increasing the power consumption of the air conditioner in the room. If the light transmission of the light-transmitting skylight is reduced to reduce the temperature rise, it will also cause the brightness in the room to decrease, which cannot meet the lighting needs of the building.

[0005] Therefore, the existing light-transmitting skylight on the roof of the building has the problems of poor lighting effect and high heat in the room. SUMMARY

[0006] The purpose of the present application is to provide a kind of skylight soft light system for building roof. It can eliminate the shadow generated by the steel frame structure after being irradiated, and alleviate the increase of heat in the room caused by external light.

[0015] The skylight soft light system for building roof has the steel frame structure, the main body part, the lower end of the main body part is connected with the light transmission film through the lower cross beam.

[0016] Compared with the prior art, the present application has the following characteristics:

[0017] (1) The present application is provided with the ground glass light transmission layer on the top of the steel frame structure, so that the external natural light can be reflected in different directions after entering, thereby irradiating on the light transmission film below the steel frame structure shelter, avoiding the formation of shadow on the light transmission film below the shelter; through the light transmission film at the bottom of the steel frame structure, the strong light directly irradiating on the light transmission film can be filtered, so that the brightness of the sheltered part and the non-sheltered part is more close, further reducing the brightness difference of different parts of the light transmission film;

[0018] (2) Through the cooperation of the lower cross beam and the indoor decoration frame, the indoor decoration frame can shield the shadow formed by the lower cross beam after connecting the light-transmitting film, so that the light-transmitting film below the lower cross beam is shielded by the indoor decoration frame and cannot be directly observed, and the remaining light-transmitting part can maintain uniform brightness, further improving the lighting effect of the light-transmitting skylight; on this basis, through the structural optimization of the light-transmitting assembly and the light-transmittance limitation of the frosted light-transmitting layer and the light-transmitting film, the light-transmittance of the light-transmitting assembly can reach 43.55%, and the overall light-transmittance of the light-transmitting skylight can reach 20.4% after superimposing the light-transmitting film, so that the lighting brightness of the light-transmitting skylight is ensured while the shadow is removed, and the discomfort caused by the direct irradiation of external light on the human body is avoided;

[0019] (3) Through the light-shielding assembly arranged on the side walls around the steel frame structure, the four edges of the steel frame structure can be shielded to avoid the light in the light-transmitting skylight from entering the surrounding ceiling frame to cause the brightness of the edge position to increase, and the reflection of the light-shielding assembly is used to improve the brightness of the light-transmitting skylight at the edge, so that a clear boundary line can be formed at the edge joint of the light-transmitting skylight, thereby improving the observability and contour aesthetics of the light-transmitting skylight at the edge;

[0020] (4) Through the cooperation of the protruding part and the transparent skylight, the four edges of the light-transmitting skylight can also be supplemented with light, so that the decrease in brightness caused by the fact that the external light cannot form diffuse reflection at the edge of the light-transmitting skylight due to the influence of the roof panel is alleviated, and the brightness of the edge position and the center position of the light-transmitting skylight tends to be consistent, further improving the overall lighting effect of the light-transmitting skylight; at the same time, when the brightness of the edge of the light-transmitting skylight is improved, the brightness difference between the light-transmitting skylight and the ceiling frame at the boundary position can be further improved, thereby further improving the prominence and clarity of the contour line;

[0021] (5) Through the cooperation of the steel frame structure, the light-transmitting assembly and the light-transmitting film, the overall light-transmitting skylight can form a sealed space, thereby playing the role of air heat insulation between the external environment and the indoor environment, avoiding the direct heat transfer from the external environment to the indoor environment through the roof structure; on the other hand, through the arrangement of the light-transmitting film, the temperature rise caused by the direct entry of external light into the room can be effectively avoided, so that the heat generated by the light can be accumulated in the light-transmitting skylight; on this basis, through the cooperation of the light-transmitting film and the sealed cavity, a secondary heat insulation function can also be played, so that the heat in the light-transmitting skylight is separated above the light-transmitting film, further reducing the influence of the high temperature of the light-transmitting skylight on the indoor environment;

[0022] Therefore, the present application can eliminate the shadow generated by the steel frame structure after being irradiated, and alleviate the increase of indoor heat caused by external light. BRIEF DESCRIPTION OF DRAWINGS

[0031] The light-transmitting assembly 2 includes the first hollow tempered laminated glass 7, the 12mm inert gas layer 8, the second hollow tempered laminated glass 9, the matt light-transmitting layer 3 and the third hollow tempered laminated glass 10 connected in turn from outside to inside; wherein the first hollow tempered laminated glass 7 can be selected from 6mm LOW-E hollow tempered laminated glass, the second hollow tempered laminated glass 9 can be selected from 6mm super white hollow tempered laminated glass, and the third hollow tempered laminated glass 10 can be selected from 6mm super white hollow tempered laminated glass.

[0032] The light transmittance of the frosted light-transmitting layer 3 is 65%, the light transmittance of the light-transmitting film 4 is 47%, and the light transmittance of the first hollow tempered laminated glass 7, the second hollow tempered laminated glass and the third hollow tempered laminated glass 10 after being stacked is 67%, so that the light transmittance of the light-transmitting assembly 2 reaches 43.55% after the frosted light-transmitting layer 3 is stacked, and the overall light transmittance of the light-transmitting roof window reaches 20.4685% by stacking the light-transmitting film 4.

[0033] The material of the frosted light-transmitting layer 3 is a 1.52mm pvb frosted film, and the material of the light-transmitting film 4 is an A-grade light-collecting tension film.

[0034] The light-shielding assembly 5 is formed by arranging a plurality of light-shielding louvers side by side, and each light-shielding louver completely covers the side wall surface of the steel frame structure 1 in the horizontal direction.

[0035] The steel frame structure 1 is provided with a suspended ceiling frame 11 around, the bottom of the suspended ceiling frame 11 is covered with a transparent frosted plate for decoration, the top of the suspended ceiling frame 11 is provided with a non-light-transmitting or low-light-transmittance roof panel 12, the roof panel 12 and the top of the steel frame structure 1 are arranged in a high-low staggered manner, the upper and lower ends of the light-shielding assembly 5 and the edges of the suspended ceiling frame 11 are mutually connected, the upper end of the steel frame structure 1 extends above the roof panel 12 and is provided with a protruding part 13 connected with the roof panel 12, the protruding part 13 is detachably connected to the top edge of the roof panel 12 and the roof panel 12 overlaps each other, and the outer wall of the protruding part 13 is provided with a transparent skylight 14 which is vertically arranged by the light-transmitting assembly 2.

[0036] The top of the light-transmitting film 4 is provided with a transparent waterproof layer 15 connected with the steel frame structure 1, and a sealed cavity is formed between the transparent waterproof layer 15 and the light-transmitting film 4.

[0037] The working principle of the present application is as follows: the frosted light-transmitting layer 3 of the steel frame structure 1 can make the external light enter and then be diffused in different directions of the steel frame structure 1 through diffuse reflection, so as to be shot on the light-transmitting film 4 below the shielding object, that is, to avoid the formation of shadows on the light-transmitting film 4 at the shielding part due to the shielding of the steel frame structure 1. The light-transmitting film 4 can filter strong light, so as to make the brightness of the bright part and other parts of the light-transmitting film 4 more close, and improve the brightness uniformity of the light-transmitting film 4 at the local position. Since the light-transmitting film 4 is installed at the bottom of the steel frame structure 1 through the lower cross beam 102, a black shadow will be formed on the light-transmitting film 4 at the position of the lower cross beam 102; and the black shadow can be shielded by the indoor decorative frame 6, so that the brightness of the light-transmitting film 4 at the visible position remains consistent.

[0038] The light-transmitting membrane 4 at the middle position of the light-transmitting skylight is subjected to more diffuse reflection of light under natural light, so that the brightness thereof is higher; the edge position of the light-transmitting skylight is subjected to the influence of the outer roof panel 12, so that the light-transmitting part around the edge position is reduced, and the brightness is relatively lower, so that the light-transmitting skylight has the phenomenon that the brightness at the middle position is higher and the brightness at the edge position is lower during use. The cooperation of the protruding part 13 and the transparent skylight 14 can compensate light at the edge position of the light-transmitting skylight, that is, external light can directly enter from the transparent skylight 14 and increase the brightness at the edge position, so that the brightness at the middle position and the edge position of the light-transmitting skylight is closer, and the lighting effect of the application is further improved.

[0039] The light at the edge position of the light-transmitting skylight is subjected to diffuse reflection, and is emitted to the side wall of the light-transmitting skylight and illuminates the suspended ceiling frame 11 outside, so that the brightness of the roof gradually becomes dark from the light-transmitting skylight to the suspended ceiling frame 11, and there is no clear boundary. The light-shielding assembly 5 at the side of the light-transmitting skylight can shield the light emitted to the suspended ceiling frame 11, and form reflection to further increase the brightness at the edge position of the light-transmitting skylight, so that the edge of the light-transmitting skylight can form a clear light-dark boundary, and the clarity of the contour line of the light-transmitting skylight is improved.

[0040] The cooperation of the steel frame structure 1 and the light-transmitting assemblies and light-transmitting membranes on both sides makes the light-transmitting skylight form an over area between the inner and outer areas of the roof, so that the light-transmitting skylight has the effect of air isolation, and effectively reduces the influence of external temperature on the room.
