Description
Technical Field
The utility model relates to an emergency apparatus field specifically relates to emergent sign lamps and lanterns of fire control and optical plate body subassembly wherein.
Background
The fire-fighting emergency marker lamp is used as a lamp for guiding people to escape in danger, is widely applied to large-scale building places such as various marketplaces, and has clear regulations on production requirements and various parameters of fire-fighting emergency lamps according to national standard GB17945-2010 due to the importance and the particularity of the lamp.
In the structure adopted by the existing fire-fighting emergency sign lamp, an LED light source is arranged on a frame, light irradiates to the front side of the frame from the position of the frame, and the purpose of lightening the sign pattern on the sign face cover is achieved by utilizing the diffusivity of the light and the reflection of the bottom plate to the light.
In the prior art, the fire emergency sign lamp includes a light guide plate or a light-transmitting member, and for the sign lamp with single-sided display, a reflective layer is attached to the inner surface of the light guide plate, and the light guide plate and the reflective layer are often attached together by glue. The structure of the pasting combination is difficult to support automatic production aiming at the plate bodies with large size and small size, but requires manual cutting of a single reflection layer and pasting of the reflection layer on the inner surface of the light guide plate, and because the pasting structure between the light guide plate and the reflection layer is difficult to support automatic production and is usually performed manually, in the pasting structure between the light guide plate and the reflection layer, a certain degree of dislocation between the reflection layer and the light guide plate and wrinkles of the reflection layer on the light guide plate are possible, so that the reflection layer cannot be completely adapted to the light guide plate, and further the optical effect of the light guide plate is influenced. Therefore, the structure of pasting between light guide plate and the reflection stratum leads to the light guide plate subassembly and even fire emergency sign lamps and lanterns the assembling also relatively poor, and the assembly efficiency is relatively low.
Similarly, the (optical) diffusion layer possibly existing in the lamp is also a bonding structure with the light-transmitting member and the light guide plate, and the bonding structure also has the defects of poor manufacturability and poor assembly property.
SUMMERY OF THE UTILITY MODEL
Based at least in part on the above-mentioned shortcomings, it is an object of the present invention to improve the assemblability and/or manufacturability (manufacturability) of fire emergency sign lamps or optical panel assemblies therein.
In order to solve the above technical problem, in one embodiment of the present application, an optical board assembly structure is redesigned, and the optical board assembly having the new structure includes:
an optical plate body;
and the cladding is compounded on the optical plate body.
Optionally, in some embodiments, the cladding layer is an optical cladding layer (i.e., a cladding layer with optical function) that coats the surface of the optical board body.
Optionally, in some embodiments, the optical plate body comprises a light guide plate and/or a light transmissive member, and the cladding layer comprises a reflective layer and/or a diffusive layer; the light guide plate is provided with a first surface and a second surface which are opposite to each other; a) The reflecting layer is coated on the first surface, and/or B) the diffusion layer is coated on the second surface or the outer surface of the light-transmitting piece.
Further optionally, in the above embodiment, the following five specific schemes a to E are included:
scheme A) when only a light guide plate exists and is used for a sign lamp with single-sided display, the reflecting layer covers the first surface, and further optionally, the diffusion layer can also cover the second surface; or,
scheme B) when the light guide plate and the light transmitting piece exist simultaneously and are used for the sign lamp with single-sided display, the inner surface of the light transmitting piece is abutted against the second surface, the reflecting layer is coated on the first surface, and further optionally, the diffusing layer is coated on the outer surface of the light transmitting piece; or,
scheme C) when only a light-transmitting member is present, the diffusion layer covers the outer surface of the light-transmitting member; or,
scheme D) when only a light guide plate exists and the light guide plate is used for a sign lamp with double-sided display, the diffusion layers are coated on the first surface and the second surface; or,
scheme E) when the light guide plate and the light transmitting piece exist simultaneously and are used for the sign lamp with double-sided display, the light transmitting piece is attached to the first surface and the second surface respectively, and the diffusion layer is coated on the outer surface of the light transmitting piece.
The reflecting layer is coated on the first surface.
Optionally, in some embodiments, the light guide plate further has a second surface opposite/facing away from the first surface;
in the first case where the optical plate body includes a light-transmitting member, the diffusion layer covers the outer surface of the light-transmitting member, and in this first case, the light guide plate may or may not be present. And in the second case that the optical plate body only comprises the light guide plate, the diffusion layer is coated on the second surface of the light guide plate.
When the optical plate body only comprises the light guide plate, the second surface coated with the diffusion layer on the light guide plate directly faces the outside of the shell through the mark hole of the mark lamp shell. When the optical plate includes both the light guide plate and the light-transmitting member, the light-transmitting member is generally installed in the mark hole of the lamp housing of the sign lamp, the second surface of the light guide plate is attached to the inner surface of the light-transmitting member, and the outer surface of the light-transmitting member, which is coated with the diffusion layer, directly faces the mark hole. When the optical plate only includes the light-transmitting member, the light-transmitting member is generally installed in the mark hole of the lamp housing of the mark lamp, and the outer surface of the light-transmitting member covered with the diffusion layer directly faces the outside of the mark hole.
Alternatively, the outer surface of the light-transmitting member may be convexly formed with a logo pattern protruding into the logo hole, exposed to the outside through the logo hole. Through this convex sign pattern on the printing opacity piece, can be with printing opacity piece block in the sign hole, promoted structural stability.
Under the condition that the optical plate body only comprises the light guide plate, a mark pattern can be formed on the second surface of the light guide plate in a planar/protruding mode, and light guide points can be distributed on the mark pattern; the mark hole has the shape of the mark pattern, and the convex mark pattern formed on the second surface of the light guide plate also protrudes into the mark hole to form a clamping structure between the mark hole and the mark hole, so that the structural stability is improved.

The plates formed by cutting are respectively used for a plurality of fire-fighting emergency sign lamps. In other words, the optical plate assembly may be small in size, for example, just suitable for fitting into a fire emergency sign housing, thereby forming a fire emergency sign light fixture. Of course, the optical plate package may also be larger in size, in which case the optical plate package within a single fire emergency sign light fixture is divided from a larger sized plate package. Moreover, an optical plate assembly several times the size of a fire emergency sign light fitting may allow: according to the shape and the inner space of a single fire emergency sign lamp, the optical plate body assembly with larger size is divided and cut, so that the optical plate body assembly with any shape for the single fire emergency sign lamp is obtained. Therefore, through the large-size optical plate body assembly, the material types can be reduced, a large number of small-size light guide plates with different shapes and different mark pattern types do not need to be prefabricated, the manufacturing difficulty and the material demand are reduced, the flexibility of material preparation of the optical plate body and the lamp shell is improved to a great extent, the manufacturability of the mark lamp is improved, and the matching degree and the mutual applicability of two different materials of the optical plate body and the lamp shell of the mark lamp are also improved.
For the large-sized optical plate assembly, if the light guide plate and the cladding layer are chemically adhered in a manual assembly mode, defective products are more easily generated due to the problems of dislocation, wrinkles and the like of the cladding layer on the plate body, and the assembly efficiency and the assembly quality are lower. Consequently, the bigger size design structure of these optics plate body subassemblies in this application supports the production of automated mode, has promoted manufacturability, the assembly nature of optics plate body subassembly and fire emergency sign lamps and lanterns.

[ technical effects ] of
In some embodiments, the light guide plate and the cladding thereon form a "composite" structure, or a "cladding" structure, or cladding on the optical surface of the light guide plate. The composite structure, in particular the cladding structure, is adapted to be integrated with the light guide plate in an automated manner by means of plastic deformation of the plastic material of the light guide plate, and the new structural design of the "cladding" in the embodiments of the present application improves the manufacturability and assembly of the optical plate body assembly with respect to the integrated structure between the light guide plate and the cladding layer, which is done in a manual chemical bonding manner.
Specifically, the composite/cladding structure between the cladding and the optical plate body ensures that the optical plate body assembly is not limited to a chemical sticking mode in the manufacturing/assembling process of the optical plate body assembly, but a reflecting layer or diffusion paper and the like can be combined to the optical surface of the light guide plate/light transmission member by utilizing the hot melting state of the light guide plate/light transmission member after the light guide plate/light transmission member is manufactured and molded.
In addition, compared with a chemical bonding structure, the cladding structure has stronger bonding firmness between the light guide plate and the cladding layer on the light guide plate, and the structural strength of the optical plate body assembly is improved to a certain extent.
In addition, in other embodiments, the optical board assembly has a size capable of being divided into a plurality of boards, so that the optical board assembly can be more suitable for automatic production under a large size, and after the optical board assembly is manufactured into the board assembly with the large size, the optical board assembly is divided into small light guide plates and small light transmission plates suitable for single sign lamp, thereby realizing batch automatic production and manufacturing efficiency of the light guide plate assembly and the light transmission plate assembly in the single sign lamp. In addition, also removed these manual operation of cutting out/pasting reflection of light paper among the prior art from, also avoided pasting between reflection of light paper and the light guide plate among the manual operation and unmatched, promoted the yields of optics plate body subassembly.
The design of the composite/clad structure of the optical board body assembly of these embodiments, as well as the improvement of the dimensions of the optical board body assembly, improves the manufacturability and/or assemblability of the light guide plate, the light-transmitting member, and even the entire luminaire.
In addition, in some embodiments, light deeper within the housing is directed into the indicia bores of the housing by the light guide plate and exits the housing, whereby the light guide plate establishes an optical channel between the interior of the housing and the indicia bores based on the light guide material, such that the face cover of the light fixture can emit light outwardly through the indicia bores to present an indicia pattern.
In another embodiment of the present invention, the optical plate body may be integrally extended to form a mark pattern protruding from the light guide plate body. The projected mark pattern is projected into the mark hole on the shell to form a light guide plate capable of displaying on a single side or two sides and a fire-fighting emergency mark lamp. The mark pattern is a part integrally connected with the light guide plate, and forms a protruding part on one side or two sides of the optical surface of the light guide plate, the protruding direction of the protruding part is different from the main extending direction of the light guide plate main body, for example, the protruding part has an included angle of about 90 degrees, so that the light guide plate main body part and the protruding mark pattern part are integrally formed by the same material, the two parts jointly define (define) a bent light propagation path, and the mark pattern as the protruding part is integrally formed by extending the light guide plate main body, so that the bent light propagation path is continuous and uninterrupted, which can be understood as that the light guide plate has both light guiding property and light transmitting property in some embodiments, and the light transmission/transmission performance of the light is improved, for example, the light in the light guide plate main body part can be smoothly and transmitted to the mark pattern with low loss to be presented to the outside through the light propagation/transmission path. Moreover, the integrally extending protruding structure of the logo pattern on the light guide plate body also simplifies the structure of the light guide plate in the logo lamp, so that the light guide plate with the simple structure is convenient to be integrally formed and manufactured by plastic deformation of the material thereof, and the assembly property of the logo lamp and the manufacturability of the light guide plate in the logo lamp are improved.
Optionally, in the fire emergency sign lamp of some embodiments, I) the optical surface of the light guide plate protruding outside the sign hole, or II) the optical surface of the light guide plate exposed to the outside through the sign hole, forms a distributed light guide point; and A) the distributed light guide points increase in size as the positions thereof are far away from the light source body; or, B) the light guide point farther from the light source body has a larger size, and the light guide point closer to the light source body has a smaller size.
Through the size (diameter for example) that this kind of leaded light point adjusted the leaded light point along with its change with the distance of the light source body such as the circuit board that has LED, can make the position farther apart from the light source body on the light guide plate, through bigger light guide point to the external stronger light of emittings, this has compensatied to a certain extent: the light in the light guide plate attenuates as the distance from the light source body increases, which makes the light intensity emitted outward from the entire light guide plate through the optical surfaces in the index holes more uniform.
In some embodiments, the light guide plate protrudes into the mark hole at a portion covering the mark hole, or protrudes out of the housing through the mark hole, that is, a side of the light guide plate facing the mark hole is not a plane but has a protrusion adapted to the mark hole, the protrusion and a main body portion of the light guide plate are integrally formed by plastic deformation of the light guide plate at a high temperature, during the installation of the lamp, the protrusion can be directly snapped into the mark hole on the surface cover/housing, and the light guide plate and the surface cover are connected by gluing, which also reduces the number of components of the lamp, simplifies the structure, and enhances the assembly.

Fig. 4a, 4b, 7a, 7b show schematic cross-sectional views of an optical plate assembly in an emergency sign light fixture according to embodiments of the present invention.
In these embodiments, a fire emergency signage light is presented, comprising:
an optical plate body assembly;
a housing FC1 provided with a mark hole H1;
and an optical plate assembly covering the mark hole H1.
Specifically, the optical plate assembly is accommodated inside the housing FC1 and exposed to the outside of the sign lamp through the sign hole H1. Alternatively, the second surface OS2 faces the outside of the case FC1 through the index hole.
Optionally, in the fire emergency sign light fixture of these embodiments, the optical plate assembly further comprises:
the optical plate bodies Tr11, SI22;
the cladding layers L19, L23 are compounded on the optical plate bodies Tr11, SI22. For example, the cladding layer is an optical cladding layer, and is coated on the surface of the optical plate Tr11, SI22.
Optionally, in some embodiments, the optical plate body Tr11, SI22 further includes a light guide plate Tr11 and/or a light transmissive member SI22. The light guide plate Tr11 has a first surface OS1 and a second surface OS2 facing/away from each other.
The cladding layer further comprises a reflective layer L19 and/or a diffusion layer L23, the reflective layer L19 cladding the first surface OS1.
In some embodiments, the optical plate assembly has dimensions that fit into a single fire emergency sign light fixture such that the optical plate assembly can be mounted directly into the housing of the fire emergency sign light fixture.
Further, the light guide plate Tr11 has a size suitable for being divided into n panels each of which P1-1, P1-2, P1-3 is used for a single fire emergency sign lamp, respectively. The first surface OS2 is distributed to form an array of 1 group of mark patterns (for example, "human figure" and the prompts on the left and right sides of the "human figure"; "safe Exit", "Exit", etc.), wherein n is an integer, and n ≧ 2.
In both embodiments shown in fig. 4a and 4b, the optical plate body only includes the light guide plate Tr11 and does not include the light-transmissive element SI22, the diffusion layer L23 covers the second surface OS2 of the light guide plate Tr11, and the reflective layer L19 covers the second surface OS1 of the light guide plate Tr 11. In the marker light fitting of the embodiment shown in fig. 4b, the light guide plate Tr11 is formed with a projection at a position corresponding to the marker hole H1, the projection portion projects into the marker hole H1, and the optical surface OS2 on the outer side of the projection portion is covered with the diffusion layer L23.
In the emergency sign lamp of the embodiment shown in fig. 4b, a sign pattern is convexly formed on the second surface OS2 of the light guide plate Tr11 at a portion corresponding to the sign hole H1, and light guide points (not shown) are distributed on the sign pattern. The marking hole H1 has the shape of a marking pattern, which is shown in reference to fig. 5a to protrude into the marking hole H1.
In both embodiments shown in fig. 7a and 7b, the optical plate body includes a light-transmitting member SI22, the sign lamp of the embodiment of fig. 7a does not include a light guide plate, while the optical plate body of the sign lamp of the embodiment of fig. 7b further includes a light guide plate Tr11, the light-transmitting member SI22 is installed in the sign hole H1, the second surface OS2 of the light guide plate Tr11 abuts against the inner surface (not labeled) of the light-transmitting member, and the outer surface OS2' of the light-transmitting member is covered with a diffusion layer L23.
Further alternatively, the outer surface OS2' of the light-transmitting member SI22 convexly forms a logo pattern protruding into the logo hole H1 to be exposed to the outside through the logo hole H1.
Further alternatively, the index hole H1 is an optical through hole, which means that the index hole H1 optically penetrates the housing, particularly the face cover FC1, without being limited to a physical penetrating structure. For example, some transparent material may be filled in the mark hole, in which case, the mark hole H1 of the face cover FC1 is not physically penetrated, but only has the transparent and light-transmitting property. In popular terms: the indicia bores H1 remain light transmissive but are not necessarily "air permeable". Accordingly, the optical surface of the light-transmitting plate SI22 is "exposed to the outside" through the mark hole H1 of the front cover FC1, or the light guide plate Tr11 or the light-transmitting plate SI22 is exposed to the outside of the mark hole, and the "exposure" is also referred to as "optical exposure", and is not limited to being physically through-exposed. For example, a transparent paper may be disposed in the mark hole H1, or the outer surface of the transparent member SI22 may be covered with a diffusion paper, so that the transparent plate tran _1 is optically exposed to the outside through the transparent paper or the diffusion paper.
The reflecting layer is used for reflecting light rays and avoiding the loss of the light rays caused by the emergence of the light rays from the first surface. The diffusion layer is generally coated on the light exit surface of the optical plate body for better emitting the light inside the optical plate body from the optical surface. Additionally, in some embodiments, the reflective layer may be implemented in the art as a reflective paper and the diffusive layer may be implemented in the art as a diffusive paper. For the fire emergency sign lamp with double-sided display (or simply referred to as emergency sign lamp, or lamp), two optical surfaces opposite to each other on the optical plate are both light-emitting surfaces, in this case, only the portions corresponding to the sign holes H1 and H2 on the two optical surfaces OS1 and OS2 of the light guide plate P1 shown in fig. 6 are covered with the diffusion layer, and the reflection layer is not covered any more. Alternatively, the lamp further includes a light-transmitting member (not shown in fig. 6), and the light-transmitting member includes two portions, the first surface OS1 and the second surface OS2 of the light guide plate P1 respectively abut against the two portions of the light-transmitting member, and the first portion and the second portion of the diffusion layer respectively cover the outer surfaces of the light-transmitting member on both sides of the light guide plate P1, which is not shown in the figure. It should be understood, of course, that the cladding structure between the optical plate body and the diffuser layer is not limited to the portion of the optical surface aligned with the index hole, and the diffuser layer clad on the optical surface of the plate body may also exceed the area of the index hole H1, and the area and shape of the diffuser layer clad on the surface of the optical plate body are merely an example and not intended to be limiting.
In addition, it should also be noted that: the optical plate, particularly a light transmitting plate, may be mounted inside or outside the lamp housing of the emergency sign lamp, for example, the light transmitting plate may cover the sign hole H1 from the outside of the face cover FC1 to isolate the inside and the outside of the housing of the lamp and transmit light inside the housing from the inside to the outside of the housing. Of course, the light-transmitting plate may be made of other materials such as glass, but is not limited to the material of the light-transmitting plastic.
In some embodiments, as shown in fig. 4a, 4b, 7a, and 7b, the optical connection may occur between the light guide plate Tr11 and the light source body LE23, or may also occur between the light-transmitting member SI22 and the light source body LE23, in the sense that: the light guide plate is connected to the light source body such that: light from the light source body may be received and conducted by the light guide plate, or light may be emitted from the light source body LE23 and conducted along the light guide plate Tr11, in which case there may be a direct physical connection between the light source body LE23 and the light guide plate Tr 11. In other embodiments, the optical connection may also occur between the light-transmitting member SI22 and the light source body LE23, and there may be no physical connection/contact therebetween, as shown in fig. 7a and 7b, in which case, the light from the light source body LE23 propagates in the inner space of the housing FC1, and is incident on the inner surface (not labeled) of the light-transmitting member SI22, then passes through the light-transmitting member SI22, and then exits from the outer surface OS2' of the light-transmitting member, so as to externally present the logo pattern. Here, the outer surface OS2' of the light-transmitting member SI22 generally means: the light transmissive member SI22 faces an optical surface outside the fire emergency sign light after being installed in the sign hole H1. The inner surface of the light-transmitting member generally means: and another optical surface opposite to the outer surface, i.e., an optical surface on the light-transmitting member facing the interior of the fire emergency sign lamp after the assembly of the lamp is completed.

Here, it can be understood that: from the outside of the light guide plate, the two faces can be regarded as being away/opposite; of course, from another angle (e.g. the inside of the light guide plate): the term "opposite/facing away" is also understood to mean: "relative" and both of these meanings refer to: the first and second surfaces of the two surfaces of the light guide plate P1 face opposite directions to the outside, or the first and second surfaces of the two surfaces of the light guide plate P1 face opposite directions to the outside.
It should be understood that: although some embodiments of the present invention and the drawings thereof only show that the sign pattern is formed by protruding on one surface of the light guide plate in the light guide plate assembly or the fire emergency sign lamp, and the sign hole is formed on one surface cover adapted to the sign pattern and the surface cover, this is not limited to that the light guide plate is formed by protruding on only a single surface, and the other surface of the light guide plate may also be formed by protruding on the sign pattern. In addition, for the light guide plate assembly or the fire emergency sign lamp with the double-sided sign patterns according to some embodiments, the matching/structural relationship between the two sides of the light guide plate assembly or the fire emergency sign lamp with the two corresponding side covers is the same/similar, and the matching/structural relationship between the sign patterns on the two sides and the sign holes formed in the two side covers is also the same/similar. The structure of the fire emergency sign lamp with the double-sided sign pattern and the two-sided cover in the embodiments can also refer to the structure of the fire emergency sign lamp with the single-sided sign pattern and the single-sided cover in other embodiments. As such, for brevity, the single-sided emergency sign light and the double-sided emergency sign light in some embodiments of the invention will be described with reference to the same drawings, and the double-sided emergency sign light in some embodiments will be described in conjunction with the single-sided emergency sign light of other embodiments.

The thickness of the light guide plate P1 gradually decreases in a direction from the first end T1 to the second end T2. From another perspective, the thickness of the light guide plate P1 where the logo pattern Pat1 is located gradually decreases in a direction from the first end T1 to the second end T2.
In the light guide plate assembly or the fire emergency sign light of some embodiments, the light guide plate P1 further includes light guide points GP1, which can be distributed on the sign pattern Pat1 or the optical surfaces OS1 and OS2 thereof with reference to fig. 5 d.
The size of the light guide point GP1 increases as the thickness of the light guide plate P1 at the portion where the light guide point GP1 is located decreases. From another perspective, the size of the light guide point GP1 on the logo pattern Pat1 gradually increases in a direction from the first end T1 to the second end T2.

The light guide plate P1 is attached to and covers the inside of the first cover FC1 and/or the second cover FC 2. To the scheme that the fire emergency sign lamp has two-sided sign patterns with two corresponding face covers, the sign patterns on two sides/two sides of the light guide plate P1 are reversely and respectively protruded into the sign hole H1 on the first face cover FC1 and the sign hole H2 on the second face cover FC1. And for the scheme that the fire emergency sign lamp displays the sign pattern on a single surface and is correspondingly provided with a surface cover FC1, the sign pattern Pat1 protrudes into a sign hole H1 on the first surface cover FC1, or the sign pattern Pat1 protrudes into a sign hole H2 on the second surface cover FC 2.
It should be understood that: the mark pattern Pat1 protrudes into the mark holes H1 and H2, and includes 1) "the mark pattern Pat1 protrudes from the light guide plate body and enters the mark holes, but does not protrude outside the mark holes", and 2) "the mark pattern Pat1 protrudes from the light guide plate body and enters the mark holes H1 and H2, and protrudes outside the mark holes through the mark holes", and so on, in general, the larger the protrusion degree of the mark pattern Pat1 is, the better the outward optical effect of the mark lamp is, and the mark pattern Pat1 can be more clearly displayed to the external vision.
In the light guide plate assembly or the fire emergency sign lamp according to some embodiments, the sign holes H1 and H2 and the sign pattern Pat1 respectively include a plurality of portions (or referred to as a plurality of sub light guide plates), as shown in the figure. This means that the symbol holes H1, H2 include a plurality of portions, and the symbol pattern Pat1 also includes a plurality of portions, and the plurality of portions of the symbol holes correspond to the plurality of portions of the symbol pattern Pat1, respectively, or one-to-one, as shown in fig. 3 and 6. This allows portions of the logo pattern Pat1 to be correspondingly snap-fitted into portions of the logo holes H1, H2; alternatively, the portions of the logo pattern Pat1 may be independent from each other or integrally connected to each other.

Optionally, in the fire emergency sign lamp according to some embodiments, the circuit board C1 is located below/above the sign hole H1 and fixed to the end of the light guide plate P1. For example, the circuit board C1 may be directly fixed to the light guide plate P1, or may be fixed to the light guide plate P1 through a case such as a front cover or a rear cover.
Alternatively, in the fire emergency sign lamp according to some embodiments, the light guide plate P1 extends from different portions of the sign hole H1 to form a plurality of sub light guide plates P1 independent of each other on the inner wall of the housing FC1.
Optionally, in the fire emergency sign lamp according to some embodiments, the circuit board C1 is in a strip shape, and the circuit board C1 is disposed below/around the sign hole H1, as shown in fig. 1. The light source body includes multiunit LED lamp pearl, lays on circuit board C1 along the strip shape, corresponds to different sub light guide plate P1 respectively, shows 3 sub light guide plate P1 in figure 1. The 3 sub light guide plates P1 respectively cover different portions of the sign hole H1, for example, corresponding 3 portions of the sign holes on the face cover FC1, such as "left arrow", "right arrow" and "human-shaped sign" shown in fig. 3, and are respectively optically connected to the sets of LED lamp beads.
Optionally, between each sub light guide plate and the LED lamp bead group, there may be one-to-one, one-to-two, one-to-three, etc., and it may depend on the size of the sign hole covered by the sub light guide plate, that is, the size of the sign pattern Pat1 corresponding to the sub light guide plate, as shown in fig. 2, the sub light guide plate covering the larger "human-shaped sign" pattern/sign hole may be provided with 4 light incident holes, and receive 4 LED lamp beads, so that the sub light guide plate conducts light to display the "human-shaped sign" sign pattern, while the sub light guide plate covering the smaller "right arrow" pattern/sign hole may be provided with 2 light incident holes, and receive 2 LED lamp beads, so that the sub light guide plate conducts light to display the "right arrow" sign pattern.
Optionally, in the fire emergency sign lamp according to some embodiments, an upper end portion or a lower end portion of each of the plurality of sub light guide plates P1 is recessed inward to form at least one light inlet LDH1 for accommodating a corresponding one of the plurality of groups of LED lamp beads (not shown in the figure); the light inlet LDH1 is not penetrated through/penetrated through the light guide plate P1.

A power cord W1 is connected to the circuit board C1 within the case FC1 and the rear cover BC1 to supply power thereto; the face cover FC1 is a stainless steel face cover FC1.
It can be understood that if the housing includes two face covers FC1, the two face covers may be provided with marking holes, and the marking patterns may be displayed in two directions away from each other. The front cover BC1 or also called back cover will not be described in detail.
FIG. 8 illustrates a light guide plate with bottom-distributed light inlets of different shapes in one embodiment. Alternatively, as shown in fig. 8, a plurality of light inlets are provided at the first end T11' to be open to the outside as a plurality of notched LDHs 1-1, LDH1-2, inner walls/bottoms of the plurality of notched LDHs 1-1, LDH1-2 forming convex or concave surfaces, respectively, toward the light source body (not shown in fig. 8); that is, the plurality of notches includes: one or more first notches with convex surfaces are formed at the bottom, and one or more second notches with concave surfaces are formed at the bottom.
Further alternatively, the bottom of the plurality of notches LDH1-1, LDH1-2 is formed with a convex first notch LDH1-1, is located at both ends of the first end portion T11' in the lateral direction of the light guide plate P1 ″, the bottom of the plurality of notches is formed with a concave second notch LDH1-2, is located at the middle of the first end portion T11' in the lateral direction (as indicated by an arrow A4 in the drawing) of the light guide plate P1 ″, in other words, the bottom of the plurality of notches is formed with a convex first notch LDH1-1, is arranged at both sides of the first end portion T11' in the lateral direction of the light guide plate P1 ″, and the bottom of the plurality of notches is formed with a concave second notch LDH1-2, is arranged in the lateral direction of the light guide plate P1 ″: the middle section of the first terminal portion T11', or between the first notched LDH1-1 on both sides of the first terminal portion T11'.
Of course, the light guide plate may include a plurality of sub light guide plates, such as 3 sub light guide plates P1-1, P1-2, P1-3 shown in FIG. 5 a. In this case, the first notches, the bottoms of which are protruded outside the notches, are located at both sides of the entire light guide plate, for example, the bottoms of the sub-light guide plates P1-1, P1-3. The second notch with its bottom recessed into the light guide plate is located in the middle of the whole light guide plate, such as the sub-light guide plate P1-2. For the sake of brevity, no further description is provided.
The structure that the light inlet is opened to the outside at the first end of the light guide plate (or opened to the outside of the light guide plate) makes the light guide plate assembly install the circuit board to the first end of the light guide plate more easily, especially with punctiform light source bodies such as LED lamp beads on the circuit board, through the opening part of the breach snap-in into these breaches that have open structure, has promoted the assemblability of light guide plate and whole lamps and lanterns.
The part towards the evagination of the light source body in the first breach can assemble the luminescence of the light source body because of its optical structure who has the convex surface, consequently, the first breach with the evagination of bottom is laid in the light guide plate both sides, can prevent to a certain extent that the luminescence of the light source body from dispersing, especially prevents to disperse from the side of light guide plate and lead to the luminous flux reduction of the main light emitting area of light guide plate outside the light guide plate. Because the part of bottom indent in the second breach can disperse the giving off light of the light source body because of its optical structure that has the concave surface to spread the light of the LED lamp pearl of pointolite form in the plate body of light guide plate, and then make the light emitting area of light guide plate give off light more evenly outward. Therefore, preferably, in some embodiments, the second notch with the concave bottom is disposed at the middle/middle portion of the first end portion of the light guide plate, so that the light of the LED lamp bead at the middle portion of the first end portion can be uniformly diffused into the whole light guide plate body, and meanwhile, since the section of the light guide plate body is not located at the periphery of the whole light guide plate, the light diffused through the concave surface is not easily dissipated out of the light guide plate body. This has also reduced the consumption to a certain extent when promoting light guide plate or lamps and lanterns and outwards giving out light the effect.
Fig. 5a is a schematic structural diagram of a light guide plate having a plurality of sub light guide plates in a cover assembly of a sign lamp according to an embodiment. Fig. 5c shows a schematic view of the overall outline (outline) of the light guide plate in fig. 5a in the left-hand direction. The structural relationship between the plurality of sub light guide plates and the structural relationship between the light guide plate and the cover, which may be implemented as a case, will be described in detail with reference to fig. 5c and 5 a.
As shown in fig. 5a, the light guide plate in this embodiment includes three parts, or 3 sub-light guide plates P1-1, P1-2, P1-3. The three sub light guide plates may be independent of each other as shown in fig. 2, or may be connected to each other as one body as shown in fig. 5 a.
The light guide plates P1-1, P1-2, P1-3 extend away from LED lamp beads (not shown in the figure) in the light inlet LDH1, and optionally, the thickness of the light guide plates P1-1, P1-2, P1-3 gradually decreases along with the extension in the direction A2. From another perspective, this means: the parts of the light guide plates P1-1, P1-2 and P1-3, which are farther away from the LED lamp beads, have smaller thickness. Thus, overall, the outline of the light guide plate in the side view direction may have a right trapezoid shape as shown in fig. 5c, for example, the thickness of the lower base of the right trapezoid light guide plate may be 2mm and gradually become thinner until the thickness of the upper base is 0.8mm. Of course, assuming that the light source body is located below the sign hole outline of the lamp, if the light source body is located above the sign hole outline, the upper base of the right trapezoid is longer and the lower base is shorter.
In addition, distributed light guide points GP1 are formed on the optical surface OS1 of the light guide plates P1-1, P1-2 and P1-3 which protrudes out of the mark holes. Or, the light guide plates P1-1, P1-2, and P1-3 are formed with distributed light guide points GP1 on the optical surface OS1 exposed to the outside through the mark holes. Optionally, the light guiding points GP1 distributed on the optical surface OS1 gradually increase in size as the positions thereof are away from the light source body. This means that: the light guiding points GP1 on the optical surface OS1, which are further away from the LED lamp bead, have larger dimensions, such as diameter or area.
From another perspective, the thickness of the portion of the light guide plate P1-1, P1-2, P1-3 covering the sign hole gradually decreases with distance from the light source body, or the thickness of the portion of the light guide plate decreases from the first end T11 to the opposite second end T22, the first end T11 is optically connected to the LED lamp bead on the circuit board below the sign hole, and the second end T22 extends to above the sign hole. The size of the light guiding point GP1 on the optical surface OS1 of the light guiding plate increases with the decreasing thickness of the light guiding plate, that is, for the light guiding point GP1 on the optical surface OS1, the smaller the thickness of the light guiding plate at the position where the light guiding point GP1 is located, the larger the size of the light guiding point GP1 is, as shown in fig. 5c and 5d, a Local3 of the light guiding plate protruding in the mark hole is taken as an illustration, the light guiding point GP1 of the portion with larger thickness (close to the first end portion T11 in the figure) has smaller size, and the light guiding point GP1 of the portion with smaller thickness (close to the second end portion T22 in the figure) has larger size.
Through a) the size of adjusting the leaded light point along with the change of the distance of leaded light point and LED lamp pearl in above-mentioned embodiment, perhaps b) the thickness of each part on the light guide plate is inversely proportional with each part light guide plate and the interval of LED lamp pearl, this write hand section all can make on light guide plate P1-1, P1-2, the position farther apart from the light source body on P1-3, through bigger leaded light point or thinner light guide plate to the light that shines out stronger, this has compensatied to a certain extent: the light in the light guide plate attenuates as the distance from the light source body increases, which makes the light intensity/brightness emitted to the outside by the optical surface in the index hole more uniform throughout the light guide plate.
Alternatively, the optical plate body LB _23 may be configured as a plate, a sphere, a cube, a prism, or the like, for example. Fig. 9 is a cross-sectional view of an optical plate body in the shape of a triangular prism or a triangular pyramid. When the optical plate body LB _23 has a plate shape, it may also be referred to as a light guide plate or a light guide plate. In the following embodiments, the plate-shaped optical plate body LB _23 is mainly taken as an example for typical description, but the optical plate body LB _23 may be implemented in other shapes without being hindered.
It should be understood that: the optical cladding layer is integrated in the light guide plate by means of plastic deformation of the plastic material of the light guide plate at a certain temperature, thereby forming a cladding structure of the light guide plate to the cladding layer.
Alternatively, in some embodiments, the mark pattern Pat1 is formed on at least one of the first surface OS1 and the second surface OS2 in a protruding manner, the mark hole H1 has a shape matched with the mark pattern Pat1, and the mark pattern Pat1 protrudes into the mark hole H1. Of course, in an alternative embodiment, the first surface OS1 and the second surface OS2 may be kept flat (flat) without forming the protruding mark pattern Pat1 at the mark hole H1, as shown in fig. 4a, 4b, 7a, 7b, and 6.
It should be understood that: "the light guide points distributed on the first surface", may be the whole distributed light guide points of a) above, and may also be the local distributed light guide points in b), and in b), when the light guide points are distributed in the "specific area" whose outer contour is in the shape of the logo pattern, the "specific area" may form the logo pattern in a plane, that is, the specific area does not protrude from the first plane but the position and shape of the specific area are defined by the light guide points distributed above (define), and may also protrude from the first surface to form the protruding logo pattern (of course, the light guide points are also distributed on the logo pattern), which is more convenient: when the first shell and the first surface are compounded/attached by gluing/gluewater, the first shell can be aligned with the mark pattern through the mark hole, so that the first shell is positioned and attached on the first surface. However, the "distribution of light guide points" in some implementations of the present application includes at least the following three cases: the light guide points may be a) distributed in the shape of a logo pattern on the first surface, or B) distributed in the shape of an outline of the logo pattern on the first surface, or C) directly distributed on the logo pattern formed in a protruding manner. In the above-mentioned scheme a), a logo pattern is actually defined by light guide points distributed on the first surface, so that the logo pattern is formed in a plane (this means: a planar logo pattern is formed on the first surface by the light guide point). And C) the scheme can be regarded as that the light guide point and the convex part on the first surface jointly define a mark pattern; and B) the scheme does not accurately define a mark pattern on the first surface, but only defines a rough outline, and the mark pattern is defined by the hollow mark holes in the shell after the first shell is compounded to the first surface. Of course, the "distribution of light guide points" in the practice of the present application also includes D) an overall distribution on the first surface, where the area of the cover (cover) included in the overall distribution includes B) the outline area of the logo pattern in the solution, but may exceed this area until the light guide points are all spread over the first surface. In addition, the light guide points can be formed by silk screen printing, injection molding or laser dotting. The light guide points are exposed along the mark holes, and may include "all of the light guide points are exposed along the mark holes" or "only a part of the light guide points are exposed along the mark holes". Generally speaking, after the first shell is covered on the first surface, the mark holes are distributed with light guide points on the externally exposed area of the first surface in a frame selection mode, and therefore, the effect of the lamp on the externally luminous mark is better. Of course, when the optical plate body is made of self-luminous materials, light guide points are basically not needed, and the whole lamp can show better mark patterns outwards.
If the first surface is fully distributed with the light guide points, the mark pattern presented to the outside by the lamp is determined by the shape of the mark hole, namely the mark hole with which shape is provided on the shell, and finally the mark pattern with which shape is presented to the outside by the lamp. This improves the versatility of the housing material for the manufacture of sign luminaires in diverse patterns and/or the flexible customizability of the sign luminaire pattern, compared to the embodiment "defining one sign pattern with light guiding points on the first surface in advance".
Alternatively, in some embodiments, the light guide plate P1 is a) integrally molded from a light transmissive plastic, or b) made from a self-luminous plastic, or c) made from a light transmissive plastic doped with a self-luminous material, or d) made from a plastic having a color/fluorescence, wherein the color/fluorescence is green.
