Description

Technical Field

[0001] This utility model relates to the field of emergency lighting equipment, specifically to an integrated pendant sign light and an integrated lamp body. Background Technology

[0002] Hanging sign lights can be used as fire emergency sign lights, suspended above building passageways to provide evacuation directions; they can also be used as directional signs to remind people of their current location, and are widely used in various large buildings.

[0003] The existing pendant-type sign light consists of a pendant, aluminum profile, end caps, plastic fixing strips, circuit board, and LED light source. The fixing strip is used to fix and protect the circuit board and LED light source, and also has an insulating function. After the circuit board and LED light source are installed in the fixing strip, the fixing strip is then installed in the aluminum profile, and then the ground wire is installed. The pendant needs to have a round hole set at the top, through which a metal strip is passed, and then the pendant is suspended on the hanging groove of the aluminum profile using the metal strip. Finally, end caps are installed at both ends of the aluminum profile to complete the assembly of the pendant-type sign light.

[0004] The structure has many components, complex steps, long assembly time, and high product cost. To ensure that the fixing strip cannot move after being installed on the aluminum profile, the dimensions of the fixing strip and the aluminum profile must be very precise. However, the aluminum profile is prone to deformation, resulting in a high scrap rate and making assembly very difficult. Some manufacturers even need to use screws for fixing. The aluminum profile and the hanging plate are fixed by metal strips and hanging grooves. The hanging plate is prone to loosening, and there are large gaps between the aluminum profile and the hanging plate, causing light to pass through the gaps, affecting the light efficiency of the lamp. Moreover, water can also enter the lamp body through the gaps, resulting in extremely poor waterproof performance of the product. Utility Model Content

[0005] To address the shortcomings of existing technologies, the purpose of this utility model is to provide an integrated hanging sign light and integrated light body that is simple in structure, robust, low in cost, easy to assemble, and highly waterproof.

[0013] Preferably, the width of the cavity is greater than the width of the opening, and the outer side of the cavity is provided with an inclined surface and connected to the opening.

[0014] Preferably, the opening and the sidewall of the housing are connected by a filled / solid connection.

[0017] B) The connecting part is inclined, narrower at the top and wider at the bottom; or,

[0018] C) The connecting part is inclined, wider at the top and narrower at the bottom.

[0019] Preferably, the housing is provided with a plate groove, and the circuit board enters the cavity from one side of the cavity by lateral movement and is fixed in the cavity by the plate groove;

[0021] B) The slot is located on the left and / or right side of the cavity, and the circuit board is arranged horizontally.

[0022] Preferably, the light-emitting plate further includes a protrusion that protrudes from the opening and extends inward in the direction of the housing.

[0023] Preferably, the height of the protrusion is equal to the distance between the side of the circuit board and the LED light source.

[0024] Preferably, the housing has through-holes on both sides of the front and rear sides of the housing, and the plug is disposed on the through-hole, and the plug has a mounting hole.

[0025] Preferably, the housing includes a housing body and an assembly edge, the notch is disposed between the assembly edge and the housing body, and the mounting hole is exposed to the outside through the notch.

[0026] To achieve and improve the manufacturing efficiency of integrated pendant sign lights, an integrated light body is also proposed, comprising:

[0027] The housing is made of opaque plastic and has a cavity that extends through both sides and an opening located below the cavity.

[0028] The light-emitting panel is made of light-transmitting / light-guiding plastic;

[0029] The opening extends through the bottom of the housing and is injection molded and welded to the front and rear sides of the light-emitting plate to form a connecting part. The height of the connecting part is 1-5 mm, and the thickness of the light-emitting plate is 1-3 mm.

The lamp body does not need to be assembled. The shell and the light-emitting plate cannot be separated. The structure is extremely strong and the cost is low. It greatly speeds up the assembly speed of the product and has excellent waterproof performance; (2) Since the length and height of the light-emitting plate of the sign light are strictly required in the national standard, the opening and the light-emitting plate are connected by injection molding and form a connecting part. When the height of the connecting part is too low, the light-emitting plate may fall off the shell. When the height of the connecting part is too high, the area of ​​the connecting part increases. When injection molding is performed, the required temperature is higher, which causes the shell to deform. Or, the local cooling of the connecting part is too fast, which causes the front and rear sides of the opening and the light-emitting plate to not be connected. The height of the connecting part is 1-6MM, which can ensure that the connection between the shell and the light-emitting plate is firm and the product is exquisite and beautiful.

Detailed Implementation

[0039] The technical solution of this utility model will be further described below with reference to specific embodiments.

[0040] like Figure 1 , Figure 2 , Figure 3As shown, this utility model provides an integrated hanging sign light, comprising: a lamp body 1, consisting of a housing 2 and a light-emitting plate 3 disposed below the housing 2; the housing 2 is made of opaque plastic, and the light-emitting plate 3 is made of translucent / light-guiding plastic; the lamp body 1 is an integral plastic profile (pull tube) formed by dual-color extrusion molding; the housing 2 has a cavity 21 penetrating both sides and an opening 22 disposed below the cavity 21; the opening 22 penetrates the lower part of the housing 2 and is injection molded and welded to the front and rear sides of the light-emitting plate 3 to form a connecting part 4; the height of the connecting part 4 is 1-5 mm; a circuit board 5, equipped with an LED light source 51, the circuit board 5 is disposed inside the housing 2, and the LED light source 51 is disposed above the light-emitting plate 3; and a plug 6, connected to and enclosed on both sides of the housing 2. The lamp body 1 is a two-color extruded plastic profile produced by a set of molds. The lamp body 1 does not require assembly. The shell 2 and the light-emitting plate 3 are inseparable, resulting in an extremely robust structure, low cost, and significantly accelerated product assembly speed. It also has excellent waterproof performance. Since the length and height of the light-emitting plate 3 of the marker light are subject to strict national standards, the opening 22 and the light-emitting plate 3 are connected by injection molding to form a connecting part 4 (i.e., utilizing the fusible property of plastic, the shell 2 is fused to the already cooled and formed light-emitting plate 3 before it has cooled and solidified, forming a continuous connection). (Connection part 4) When the height of the connection part 4 is too low, the area of ​​the connection part 4 is too small, and the light-emitting plate 3 may fall off the housing 2; when the height of the connection part 4 is too high, the area of ​​the connection part 4 increases, and the required temperature during injection molding is higher, which may cause the housing 2 to deform, or the local cooling of the connection part 4 may be too fast, causing the opening 22 and the front and rear sides of the light-emitting plate 3 to not be connected. Therefore, the height of the connection part 4 is set to 1-6 mm to ensure a firm connection between the housing 2 and the light-emitting plate 3, and the product is exquisite and beautiful.

[0041] The light-emitting plate 3 includes an inner shell portion 31 and a display portion 32. The inner shell portion 31 is disposed inside the housing 2, and the display portion 32 is disposed below the inner shell portion 31. The connecting portion 4 is disposed on the inner shell portion 31. The thickness of the display portion 32 is 1-3 mm. Since the length and height of the light-emitting plate 3 of the sign light are subject to strict requirements in national standards, if the display portion 32 is too thin, the light-emitting plate 3 will crack under stress, while if the display portion 32 is too thick, the light-emitting plate 3 will have poor light guiding properties.

[0042] The display section 32 has a cross-section that is wider at the top and narrower at the bottom. The thickness of the display section 32 near the housing 2 A is greater than the thickness of the part away from the housing 2 B. Since the LED light source 51 is located above the light-emitting plate 3, the light from the LED light source 51 shines from top to bottom. The light will attenuate due to the illumination distance. Therefore, the brightness of the upper part of the light-emitting plate 3 will be higher than the brightness of the lower part of the light-emitting plate 3. This structure can increase the brightness of the lower part of the light-emitting plate 3, making the overall brightness of the light-emitting plate 3 more uniform and the light effect better.

[0043] The circuit board 5 is provided with a driving element and / or a battery. Therefore, the width of the cavity 21 is greater than the width of the opening 22. The outer side of the cavity 21 is provided with an inclined surface and connected to the opening 22. In some embodiments, the cavity 21 is rectangular and the opening 22 is located below the cavity 21.

[0044] In traditional structures, since aluminum profiles are metal, and metals have strong load-bearing capacity and high hardness, due to cost constraints, the opening and the side wall of the aluminum profile are hollow structures. This structure can support the light-emitting plate 3 and is simple to process. However, since the shell 2 in this utility model is made of plastic, the opening 22 and the side wall of the shell 2 are filled / solid connections, which can ensure that the load-bearing capacity of the connecting part 4 is strong enough to prevent the opening 22 from cracking.

[0045] The shape of the opening 22 is adapted to the shape of the connecting part 4; the connecting part 4 is vertically arranged perpendicular to the horizontal plane; or, the connecting part 4 is inclined with a narrower top and a wider bottom; or, the connecting part 4 is inclined with a wider top and a narrower bottom. This structure ensures that the opening 22 and the front and rear sides of the light-emitting plate 3 are tightly connected after injection molding and welding, and the shape of the connecting part 4 can also be adjusted according to production conditions (such as the thickness, shape, and position of the LED light source 51) to increase the adaptability of the product.

[0046] The housing 2 is provided with a slot 23. The circuit board 5 enters the cavity 21 from one side by moving laterally and is fixed in the cavity 21 by the slot 23. The slot 23 is located on the upper and / or lower side of the cavity 21. The circuit board 5 is vertically arranged. This structure can prevent the circuit board 5 from shifting and ensure that the circuit board 5 is assembled stably. In some embodiments, the slot 23 is located on the left and / or right side of the cavity 21, and the circuit board 5 is horizontally arranged.

[0047] The light-emitting plate 3 also includes a protrusion 33 that protrudes from the opening 22 and extends inward into the housing 2. The height of the protrusion 33 is equal to the distance between the side of the circuit board 5 and the LED light source 51. This structure facilitates the production of the circuit board 5, reduces the defect rate and cost, and ensures that the light from the LED light source 51 is fully utilized.

[0048] The housing 2 has through-holes 24 on both sides of the front and rear sides of the housing 2. The plug 6 is disposed on the through-holes 24 and has a mounting hole 61. The housing 2 includes a housing body and an assembly edge 25. The through-holes 24 are disposed between the assembly edge 25 and the housing body. The mounting hole 61 is exposed to the outside through the through-holes 24.

[0049] To achieve and improve the manufacturing efficiency of integrated pendant sign lights, such as Figure 4 , Figure 5 As shown, an integrated lamp body is also proposed, comprising: a housing 2 made of opaque plastic, the housing 2 having a cavity 21 extending through both sides and an opening disposed below the cavity 21; a light-emitting plate 3 made of light-transmitting / light-guiding plastic; wherein, the opening 22 extends through the lower part of the housing 2 and is injection molded and welded to the front and rear sides of the light-emitting plate 3 to form a connecting part 4, the height of the connecting part 4 being 1-5 mm, and the thickness of the light-emitting plate 3 being 1-3 mm. The lamp body 1 is a two-color extruded plastic profile produced by a set of molds. The lamp body 1 does not require assembly. The shell 2 and the light-emitting plate 3 are inseparable, resulting in an extremely robust structure, low cost, and significantly accelerated product assembly speed. It also has excellent waterproof performance. Since the length and height of the light-emitting plate 3 of the sign light are subject to strict requirements in national standards, the opening 22 and the light-emitting plate 3 are connected by injection molding to form a connecting part 4 (i.e., utilizing the fusible property of plastic, the light-emitting plate 3 is fused to the shell 2 before it cools and solidifies, forming the connecting part 4). If the height of the connecting part 4 is too low, the area of ​​the connecting part 4 will be too small, and the light-emitting plate 3 may fall off the shell 2. If the height of the connecting part 4 is too high, the area of ​​the connecting part 4 will increase, requiring a higher temperature during injection molding, which may cause the shell 2 to deform or the connecting part 4 to cool too quickly in some areas, preventing the front and rear sides of the opening 22 and the light-emitting plate 3 from connecting. The height of the connecting part 4 is 1-6 mm, which ensures a firm connection between the shell 2 and the light-emitting plate 3, resulting in a refined and aesthetically pleasing product.

[0050] To accelerate the manufacturing efficiency of the integrated lamp body 1, the integrated lamp body 1 used in a sign light is not molded separately, but is pulled (extruded) as a whole by a set of molds (equipment), and then cut according to the required size and quantity. Therefore, the integrated lamp body 1 is provided with a cut 7, which divides the integrated lamp body 1 into a first lamp body and a second lamp body. The cross-section of the first lamp body and the cross-section of the second lamp body are the same.

[0051] The cross-section of the light-emitting plate 3 is wider at the top and narrower at the bottom, and the thickness of the portion of the light-emitting plate 3 closer to the housing 2 is greater than the thickness of the portion farther away from the housing 2.

[0052] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
