Description

Technical Field

[0001] The present invention relates to the technical field of light guide lighting, and in particular to a light transmission lighting system for dangerous or non-electrical areas. Background Art

[0002] At present, some flammable gases or dusts exist or are produced in important places such as coal mines, chemical industry, petroleum, military industry, aerospace, and medicine in China. When flammable gases or dusts encounter electric sparks, explosions are prone to occur. In order to ensure safety, these places all use explosion-proof lamps. However, the quality of explosion-proof lamps on the market is uneven, resulting in explosion accidents every year and heavy losses.

[0003] In recent years, a new lighting system has been developed in China that uses optical fiber to guide sunlight into the room. Its working principle is to efficiently collect natural light through a skylight and introduce it into the system for redistribution. After being transmitted and intensified by specially made light pipes, the diffuser at the bottom of the system evenly and efficiently irradiates the natural light to any place where light is needed, thereby obtaining a special lighting effect brought by natural light.

[0004] However, at night or on cloudy days, when there is no sunlight or the light is weak, the sunlight cannot meet the lighting conditions, which makes the light intensity of the optical waveguide lighting system unstable and unable to meet the daily lighting needs of all-weather. Therefore, in order to ensure the stability of the light intensity, it is also necessary to equip an electric lighting system to compensate for the defect of insufficient light intensity of the optical waveguide lighting system when natural light is weak. However, this will make the lighting system complicated and increase the installation cost and subsequent maintenance cost. Summary of the invention

[0005] In view of the shortcomings of the prior art, the present invention provides a light transmission lighting system for dangerous or powerless areas, which solves the problem that the existing light transmission lighting system for dangerous or powerless areas needs to be equipped with an electric lighting system to ensure lighting stability, resulting in a complex lighting system and high installation and maintenance costs.

[0006] The above technical objectives of the present invention are achieved through the following technical solutions:

[0007] A light transmission lighting system for dangerous or powerless areas, comprising a light source and an outdoor light beam transmission conduit located outside a building, wherein the light source is aligned with the light input end of the outdoor light beam transmission conduit, the light output end of the outdoor light beam transmission conduit is connected to a first indoor light beam transmission conduit, the first indoor light beam transmission conduit is installed inside a building wall, the light output end of the first indoor light beam transmission conduit extends into the interior of the building and is connected to a diffuse reflection lamp.

[0008] Preferably, the light source is connected to a light collimator. The advantage of such a setting is that the light emitted by the light source can be preliminarily trimmed to make the light a parallel beam, thereby reducing the light beam diffusion angle, so that the light emitted by the light source can be completely emitted into the outdoor light beam transmission duct, thereby reducing the light transmission loss and improving the lighting brightness of the lighting system.

[0009] Preferably, a beam splitter is installed in the light output end of the outdoor light beam transmission conduit, and the beam splitter includes a beam receiving end and a beam separating end. The beam receiving end is installed in the light output end of the outdoor light beam transmission conduit, and the beam separating end is installed in the light input end of the first indoor light beam transmission conduit. The advantage of such an arrangement is that the light is projected more evenly into the interior of the building, effectively improving the lighting uniformity and lighting experience of the lighting system.

[0010] Preferably, the light emitted by the light source is uniform light corrected by a shaping focusing lens. The advantage of such a setting is that the light incident into the outdoor light beam transmission duct can be made more uniform and regular, so that the brightness loss of the light after being introduced into the interior of the building by the outdoor light beam transmission duct and the first indoor light beam transmission duct is small, thereby improving the lighting brightness of the lighting system.

[0011] Preferably, the first indoor light beam transmission duct is equipped with light beam turning, folding, expanding and focusing lenses as needed. The advantage of such an arrangement is that the multiple sub-beams separated by the beam splitter can be transmitted to the diffuse reflection lamp more smoothly, ensuring smooth light transmission and lighting.

[0012] Preferably, the diffuse reflection lamp is equipped with a mechanical switch having multiple gears. The mechanical switch can limit the intensity of the light beam entering the diffuse reflection lamp. The advantage of such a setting is that the intensity of the light shining into the interior of the building can be adjusted to a suitable range by opening and closing the mechanical switch to adjust different gears, thereby improving the user experience of the light transmission lighting system.

[0013] Preferably, a beam adjuster is also installed in the outdoor light beam transmission duct, and the beam adjuster is located between the light source and the light beam receiving end. The advantage of such a setting is that the beam adjuster can be used to adjust the amount of light passing through or change the propagation path of the light, thereby achieving precise light control, ensuring that the light can be efficiently transmitted to the interior of the building, and improving the reliability of the lighting system.

[0014] Preferably, an optical filter amplifier is also installed in the outdoor light beam transmission duct, and the optical filter amplifier is located between the light beam adjuster and the light beam receiving end. The advantage of such a setting is that the light intensity can be enhanced, thereby improving the lighting intensity of the lighting system and further improving the reliability of the lighting system.

[0015] Preferably, the light-emitting end of the first indoor light beam transmission conduit is connected to a lamp connector, and the diffuse reflection lamp is connected to the light-emitting end of the first indoor light beam transmission conduit via the lamp connector. The advantage of such an arrangement is that it is easy to disassemble the diffuse reflection lamp, thereby making the replacement and maintenance operations of the diffuse reflection lamp more convenient, thereby improving the convenience and reliability of the lighting system.

[0016] Preferably, it also includes a second indoor light beam transmission duct installed inside the building wall, the light input end of the second indoor light beam transmission duct extends to the upper side of the building top wall and is connected to a light collector, the light output end of the second indoor light beam transmission duct extends into the interior of the building and is connected to a diffuse reflection lamp through a lamp connector. The advantage of such an arrangement is that natural light can be used for lighting when there is sufficient external light, which can effectively reduce the energy consumption of the lighting system and improve the economy and reliability of the lighting system.

[0017] In summary, the present invention mainly has the following beneficial effects:

[0018] 1. Through the provided light source and the first indoor light beam transmission duct, light can be provided by the light source, and the light source is installed in a safe area outside the building, thereby avoiding the power system of the light source causing safety hazards in dangerous areas that need lighting, and the light source of the lighting system is outside the building, so it can provide lighting for areas without electricity. At the same time, the light source can provide sufficiently stable light intensity for the interior of the building, thereby improving the lighting stability and reliability of the lighting system.

[0019] 2. By setting up the beam adjuster and the optical filter amplifier, the beam adjuster 5 can be used to adjust the amount of light passing through or change the propagation path of the light, so as to achieve precise light control, ensure that the light can be efficiently transmitted to the interior of the building, and improve the reliability of the lighting system. At the same time, the optical filter amplifier can enhance the light intensity, thereby improving the lighting intensity of the lighting system and further improving the reliability of the lighting system.

DETAILED DESCRIPTION

[0022] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0023] See also Figure 1 , a light transmission lighting system for dangerous or non-electrical areas, comprising a light source 1 and an outdoor light beam transmission conduit 2 located outside a building, the light source 1 is aligned with the light inlet end of the outdoor light beam transmission conduit 2, the light outlet end of the outdoor light beam transmission conduit 2 is connected with a first indoor light beam transmission conduit 3, the first indoor light beam transmission conduit 3 is installed inside the building wall, the light outlet end of the first indoor light beam transmission conduit 3 extends into the interior of the building and is connected with a diffuse reflection lamp 4;

[0024] The light source 1 is driven by a power system to emit light, and the power system can be a battery, an external power supply, a diesel generator or a gasoline generator, etc.

[0025] The light source 1 is connected to a light collimator 31 .

[0026] Specifically, the light emitted by the light source 1 can be preliminarily trimmed to make the light a parallel beam, thereby reducing the beam diffusion angle, so that the light emitted by the light source 1 can all be emitted into the outdoor beam transmission conduit 2, reducing the light transmission loss and improving the lighting brightness of the lighting system.

[0027] Among them, a beam splitter 32 is installed in the light output end of the outdoor beam transmission conduit 2, and the beam splitter 32 includes a beam receiving end 321 and a beam separating end 322. The beam receiving end 321 is installed in the light output end of the outdoor beam transmission conduit 2, and the beam separating end 322 is installed in the light input end of the first indoor beam transmission conduit 3.

[0028] Specifically, after receiving the light transmitted from the outdoor light beam transmission duct 2 through the light beam receiving end 321, the received light beam can be separated into multiple sub-beams through the light beam separation end 322, so that the multiple sub-beams can be fully reflected and transmitted in the first indoor light beam transmission duct 3, and the light can be more evenly incident on the diffuse reflection lamp 4, so that the light can be more evenly projected into the interior of the building, effectively improving the lighting uniformity and lighting experience of the lighting system.

[0029] The light emitted by the light source 1 is uniform light corrected by a shaping and focusing lens.

[0030] Specifically, the light incident into the outdoor light beam transmission duct 2 can be made more uniform and regular, so that the brightness loss of the light after being introduced into the interior of the building by the outdoor light beam transmission duct 2 and the first indoor light beam transmission duct 3 is small, thereby improving the lighting brightness of the lighting system.

[0031] Wherein, the first indoor light beam transmission conduit 3 is equipped with light beam turning, folding, expanding and focusing lenses as required.

[0032] Specifically, the distribution of beam rotation, folding, expansion and focusing can be designed according to the laying path of the first indoor light beam transmission conduit 3, so that the multiple sub-beams separated by the beam splitter 32 can be more smoothly transmitted to the diffuse reflection lamp 4, ensuring smooth light transmission and lighting.

[0033] The diffuse reflection lamp 4 is equipped with a mechanical switch, which has multiple gears. The mechanical switch can limit the intensity of the light beam entering the diffuse reflection lamp 4.

[0034] Specifically, different gears are adjusted by a mechanical switch so that the intensity of light entering the interior of the building is within a suitable range, thereby improving the user experience of the light transmission lighting system.

[0035] A beam adjuster 5 is also installed in the outdoor beam transmission conduit 2 , and the beam adjuster 5 is located between the light source 1 and the beam receiving end 321 .

[0036] Specifically, the light beam adjuster 5 can be used to adjust the amount of light passing through or change the propagation path of the light, so as to achieve precise light control, ensure that the light can be efficiently transmitted to the interior of the building, and improve the reliability of the lighting system.

[0037] An optical filter amplifier 6 is also installed in the outdoor optical beam transmission conduit 2 , and the optical filter amplifier 6 is located between the optical beam adjuster 5 and the optical beam receiving end 321 .

[0038] Specifically, the light intensity can be enhanced, thereby improving the lighting intensity of the lighting system and further improving the reliability of the lighting system.

[0039] The light-emitting end of the first indoor light beam transmission conduit 3 is connected to a lamp connector 33 , and the diffuse reflection lamp 4 is connected to the light-emitting end of the first indoor light beam transmission conduit 3 via the lamp connector 33 .

[0040] Specifically, it is convenient to disassemble the diffuse reflection lamp 4, thereby making the replacement and maintenance operations of the diffuse reflection lamp 4 more convenient, thereby improving the convenience and reliability of the lighting system.

[0041] It also includes a second indoor light beam transmission duct 7 installed inside the building wall, the light input end of the second indoor light beam transmission duct 7 extends to the upper side of the building top wall and is connected to a light collector 8, and the light output end of the second indoor light beam transmission duct 7 extends into the interior of the building and is connected to a diffuse reflection lamp 4 through a lamp connector 33.

[0042] Specifically, external natural light can be transmitted into the interior of the building through the light collector 8 and the second indoor light beam transmission duct 7, so that natural light can be used for lighting when there is sufficient light outside. This can effectively reduce the energy consumption of the lighting system and improve the economy and reliability of the lighting system.

[0043] Working principle: When there is sufficient light outside the building, the natural light is collected by the light collector 8, and then transmitted to the diffuse reflection lamp 4 through the second indoor light beam transmission duct 7. Then the natural light is emitted into the interior of the building through the diffuse reflection lamp 4 to provide lighting.

[0044] When the external light intensity is insufficient, the light source 1 can be started to emit light, and then the light is trimmed by the light collimator 31 and the beam adjuster 5 and transmitted to the optical filter amplifier 6 to enhance the light intensity. The enhanced light is dispersed into multiple sub-beams by the beam splitter 32, and then the multiple sub-beams are transmitted to the diffuse reflection lamp 4 under the transportation of the first indoor beam transmission conduit 3. Finally, the light emitted by the light source 1 is projected into the interior of the building to provide lighting.

[0045] By adjusting the mechanical switch on the diffuse reflection lamp 4 to different gears, the intensity of light shining into the interior of the building can be within a suitable range, thereby improving the user experience of the light transmission lighting system.

[0046] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
