[0005] Specifically, the angle between the projection assembly and the projection surface is C, and the film is arranged perpendicular to the optical axis direction of the projection light source;

[0006] When the projection surface with the preset mark is rotated accordingly by an angle C, the line between the projection light source and the outline of the preset mark passes through the outline of the anti-deformation pattern on the film.

[0007] Specifically, the projection assembly includes a projection lens assembly and a shading cover. The shading cover is arranged adjacent to the lighting assembly and has a projection channel.

The light emitted by the lighting component does not affect the projection light of the projection component on the outside, so that the projection effect is guaranteed. The lamp can take into account both the lighting effect and the projection effect, and has a good application effect. BRIEF DESCRIPTION OF THE DRAWINGS

In the description of the present invention, unless otherwise specified, "multiple" means two or more.

[0048] The various specific technical features and embodiments described in the specific implementation methods can be combined in any suitable manner unless there is any contradiction. For example, different implementation methods can be formed by combining different specific technical features / embodiments. In order to avoid unnecessary repetition, the various possible combinations of the specific technical features / embodiments in the present invention will not be described separately.

[0049] like Figures 1 to 9As shown, a lamp provided by an embodiment of the present invention includes a housing assembly, a lighting assembly 20 and a projection assembly 30, wherein the projection assembly 30 is used to project a preset mark onto a projection surface at a set oblique angle. The lighting assembly 20 and the projection assembly 30 are arranged in the housing assembly, and the housing assembly includes a light-transmitting cover 12 and a main housing 11, wherein the light-transmitting cover 12 is connected to the main housing 11. The projection assembly 30 is arranged adjacent to the lighting assembly 20, and the lighting assembly 20 faces the middle of the inner side of the light-transmitting cover 12. The projection assembly 30 is arranged obliquely relative to the lighting assembly 20 and faces the inner side of the light-transmitting cover 12. When the lamp is installed in the middle of the lane, the projection assembly 30 can be obliquely facing the longitudinal walls on both sides of the lane; the projection assembly 30 includes a projection light source 32 and a film sheet arranged in front of the projection light source 32, and the film sheet has an anti-deformation pattern, and the anti-deformation pattern is arranged corresponding to the logo according to the set oblique angle. In this way, when the projection assembly 30 is obliquely facing the projection surface, through the correction of the anti-deformation pattern, under the condition of oblique projection, the preset logo shape projected on the projection surface is the required logo shape (for example, a standard arrow shape), and the required preset logo shape can be obtained without facing the projection assembly 30 directly to the projection surface, so that the projection assembly 30 can be integrated into the lamp and installed above the lane, and there is no need to additionally wire the wall and separately set the escape logo indicator light, and the lamp is easy to install and has low application cost.

[0050] Specifically, in the assembled lamp, the film is arranged perpendicular to the optical axis direction of the projection light source 32. When the lamp is suspended or ceiling mounted above the central area of ​​the lane, the angle between the projection assembly 30 (optical axis direction of the projection light) and the preset projection surfaces on both sides (the walls on both sides of the lane) is C.

[0051] When designing the anti-deformation pattern of the film, as shown in Figure 10(a), the projection component 30 is first calibrated to set a distance perpendicular to the projection surface 901 (the rectangular frame surface in a vertical state), and the outline of the preset mark is designed on the projection surface 901. When the projection surface with the preset mark is rotated by an angle C along the arrow of Figure 10(a), a connecting line is formed between the projection light source 32 and the outline of the preset mark on the projection surface 901 after the rotation angle C, and the connecting line passes through the outline of the anti-deformation pattern on the film 37. In this way, the outline of the anti-deformation pattern can be determined on the film.

[0052] In this embodiment, the preset mark takes an arrow mark as an example, as shown in FIG. 10( b ), it is the anti-deformation pattern and size on the film 37 , and as shown in FIG. 10( c ), it is the preset mark and size on the projection surface.

[0053] During the design, the anti-deformation pattern is designed according to the set oblique angle and the preset mark. The design steps can be referred to as follows: as shown in Figure 10 (c), the preset mark pattern to be projected is first drawn through the software, and the projection component 30 is designed to set the distance to the preset mark pattern. After the preset mark pattern is rotated by an angle C, the projection mark pattern is connected with the light-emitting point (projection light source position) of the projection component 30. The connecting lines of each point pass through the film to form multiple intersections. These intersections are connected to obtain the anti-deformed film pattern (anti-deformation pattern).

[0054] As shown in Figure 15(a), the warning sign and size diagram of the lamp on the side wall (projection surface) are shown. The shape of the warning sign is an equilateral triangle. Figure 15(b) is the reverse deformation pattern and size diagram of the above warning sign. As shown in Figure 16(a), the high-voltage electricity sign (electric shock warning) and size diagram of the lamp on the side wall (projection surface) are shown. Figure 16(b) is the reverse deformation pattern and size diagram of the above high-voltage electricity sign. As shown in Figure 17(a), the fire prevention sign (fire prevention warning) and size diagram of the lamp on the side wall (projection surface) are shown. Figure 17(b) is the reverse deformation pattern and size diagram of the above fire prevention sign.

[0055] It can be seen that the warning sign and size (preset sign) obtained by the projection of the lamp have a set relationship with the anti-deformation pattern and size on the film. The warning sign (preset sign) obtained by the actual projection on the projection surface is set perpendicular to the direction of the projection light source, and then the warning sign (preset sign) is rotated around the set axial fixed point by a set angle C (for example, 40 degrees). The above-mentioned fixed point is used as a reference scaling point, and the rotated preset sign is reduced by a set multiple (for example, 480 times) at the reference scaling point, so as to obtain the corresponding anti-deformation pattern and size. The corresponding anti-deformation pattern and size can be set on the film. In this way, in the application scenario of oblique projection, the standard required preset sign can also be projected on the non-front projection projection surface. In specific applications, the film can be designed to be replaceable by movably inserting the projection component. The film can be connected to the slot of the projection component by snap-fit, bonding, magnetic suction and other structures to facilitate the replacement of different films to meet different usage requirements.

[0056] During specific assembly, the film is perpendicular to the optical axis of the projection light source 32, and when the angle between the optical axis direction of the projection light source 32 and the projection surface is angle C, the required projection mark can be projected on the projection surface by correcting the anti-deformation pattern on the film. It can be understood that when the assembled projection assembly 30 is perpendicular to the projection surface, a projection pattern proportional to the anti-deformation pattern will be directly projected on the projection surface. When the projection assembly 30 is facing the projection surface at the set angle C, a standard preset mark can be obtained on the projection surface.

[0057] Optionally, the projection assembly 30 includes a shading hood 31, a projection light source 32 and a projection lens assembly. The shading hood 31 can block part of the light emitted by the lighting assembly 20, which can prevent the light of the lighting assembly 20 from affecting the projection effect of the projection assembly 30 to a certain extent, making the projection mark clearer, so as to facilitate the application of special scenes (occasions with high requirements for escape indication effects). The bottom of the shading hood 31 is connected to a base 35. The shading hood 31 is arranged on one side of the lighting assembly 20, and the shading hood 31 has a projection channel. The projection lens assembly is arranged in the projection channel. The projection light source 32 extends into the projection channel and faces the projection lens assembly. Optionally, the projection lens assembly includes a first single-sided convex lens 351, a double-sided convex lens 352 and a second single-sided convex lens 353 arranged in sequence along the projection channel from the projection light source 32. The film can be arranged between the first single-sided convex lens 351 and the double-sided convex lens 352, which has a compact structure and good projection effect.

[0058] Specifically, the lighting assembly 20 includes a lighting source plate 29 and a lighting lens 231 disposed on the lighting source plate 29. The lighting lens 231 is used to make the angle B between the light emitting angle of the lighting assembly 20 and the normal line F smaller than the angle B between the projection assembly 30 and the normal line F, that is, the light emitted by the lighting assembly 20 is refracted by the lighting lens 231 and converges toward the center (normal line) of the lighting assembly 20, and the light emitted by the lighting assembly 20 does not affect the projection light of the projection assembly 30 on the outside. Fig.13 As shown, the projection effect is guaranteed, and because the angle between the light-emitting angle of the lighting component 20 and the normal is smaller than the angle between the projection component 30 and the normal, the brightness of the lighting component 20 can be set to be higher, and the lamp can be used in alleys, etc. while taking into account both the lighting effect and the projection effect, and the application effect is good.

[0059] Optionally, the projection assembly 30 is provided with two groups, and the two groups of projection assemblies 30 are symmetrically arranged on both sides of the lighting assembly 20, and the angle A between the optical axis direction of the projection assembly 30 and the normal of the lighting assembly 20 is 50 to 70 degrees; the lighting lens 231 is used to make the angle B between the light emitting angle of the lighting assembly 20 and the normal less than 50 degrees. The lamp can be used in the lane and hoisted or ceiling-mounted in the middle of the upper part of the lane. At this time, along the lane width direction, the projection assembly 30 is located on both sides of the lighting assembly 20, and the projection assembly 30 can project indication marks (such as evacuation direction indication marks, etc.) to the side walls of the lane on both sides. The projection light source 32 of the projection assembly 30 can use a green light source, and the lighting assembly 20 can use a white light source. The white light source (LED) can use 1505010308 Everlight 5050-24V 70 CRI 5700K LED. The green light source can use 1505010072 OSRAM LT CP7P green LED with a wavelength of 513nm-537nm.

[0060] Specifically, a metal mesh cover 15 can be provided on the outside of the light-transmitting cover 12, which has good reliability. A pressure ring 13 is connected to the inner thread of the main shell 11. The pressure ring 13 is pressed on the circular edge of the light-transmitting cover 12 to fix the light-transmitting cover 12 to the main shell 11. A sealing ring can be provided between the circular edge and the pressure ring 13 to improve the explosion-proof effect.

[0061] Optionally, the lighting source board 29 is close to the bottom of the light shield 31, and the side 301 of the light shield 31 close to the lighting source board 29 is a vertical plane perpendicular to the lighting source board 29, and the light shield 31 has a light outlet hole 302 and the light outlet hole 302 is higher than the lighting source board 29, forming a height difference, that is, the lighting source board 29 is sunken inward between the two projection components 30, and the lighting light is blocked by the light shield 31 on both sides of the width direction, which can further prevent the lighting light from affecting the projection light. The side 301 of the light shield 31 close to the lighting source board 29 can also be designed as an inwardly inclined surface, that is, the angle between the side of the light shield 31 close to the lighting source board 29 and the light source board can be less than 90 degrees, the light shield 31 has a better shielding effect on the lighting source board 29 in the direction of both sides, and the light output of the lighting light in the length direction of the lane is not affected. A side surface 301 of the light shield 31 close to the lighting source plate 29 may be provided with a reflective layer, and the reflective layer may be a reflective coating or an aluminum foil layer, etc., which is beneficial to improving the lighting effect.

[0062] Optionally, the lighting lens 231 is long and narrow in shape and has an arc-shaped outer side. It is a long and narrow lens with a light distribution angle of 120°×60°. The measured half-intensity angle of the light source in the lighting component 20 can reach 153.3°. The simulated lamp is installed at a height of 3.5m and the average illumination within a range of 10*5m on the ground can reach 32lx. The lighting lens 231 has a width direction and a length direction. The two projection components 30 are respectively arranged on both sides of the lighting component 20 along the above-mentioned width direction. The lighting lens 231 is used to make the angle between the luminous angle of the light of the lighting component 20 in the width direction and the normal line not greater than 40 degrees, and the angle between the projection direction of the projection component 30 and the normal line is 50 degrees. In this embodiment, Fig.13 As shown, the angle between the luminous angle of the light of the lighting assembly 20 in the width direction and the normal is not greater than 40 degrees, the angle between the projection direction of the projection assembly 30 and the normal is 50 degrees, and the green light emitting area 303 of the projection assembly 30 and the white light illumination area ( Fig.13 The light emitting angle of the lighting lens 231 in the C90 / 270° direction and the normal are 40°, which is smaller than the angle of 50° between the projection component 30 and the normal. Therefore, the interference of the white light of the projection component 30 of the lighting component 20 on the green light is effectively reduced, ensuring the clarity of the projection while ensuring the lighting effect.

[0063] As a comparative example, the lighting component uses a narrow lens with a light distribution angle of 150°×75°. Its light distribution diagram is shown in Figure 14(a). The narrow lens 3D file is imported into Lighttools, and ray tracing is performed after adding the 5050 ray file. After the tracing is completed, the IES file is exported and placed in the Dialux software. After the corresponding scene environment is established, the lighting simulation is performed. The test diagram is shown in Figure 14(b). The simulated lamp is installed at a height of 3.5m, and the average illuminance within the range of 10*5m on the ground is 68lx>30lx, which meets the requirements. However, there is obvious light on the wall at this time. An illuminance detector is placed on the wall. The maximum illuminance of white light on the wall is 60lx, while the measured green light is only 15lx. Too high illuminance of white light will affect the green light projection effect. The maximum illuminance on the wall is 60lx, and the illuminance at a height of 2m from the ground is still 40lx, which cannot meet the requirement of ≤25lx for the white light illuminance at the center of the wall projection.

[0064] In this embodiment, the light distribution diagram of the lighting assembly 20 can be shown in Figure 12(c). The light distribution angle of the lighting lens 231 is 120°×60°, and the corresponding light distribution schematic diagram is shown in Figure 12(a). After simulation under the same conditions as the above comparative example, the test diagram is shown in Figure 12(b). The average illuminance within the range of 10*5m on the ground is measured to be 89lx>30lx, the maximum illuminance on the wall is 16lx, and the maximum illuminance of white light at the projection center is 10lx<25lx, which all meet the design requirements.

[0065] Optionally, the angle between the projection component 30 and the longitudinal projection plane is C, and the film has an anti-deformation pattern corresponding to the projection mark. When the projection mark is deflected at an angle C relative to the projection light source 32 and the distance relative to the projection light source 32 is a set projection distance, the line between the projection light source 32 and the outline of the projection mark passes through the film to form an anti-deformation pattern. Since in this embodiment, the projection component 30 and the projection wall (longitudinal projection plane) form an angle of 40°, if the projected pattern does not need to be deformed, the pattern on the film needs to be anti-deformed. The standard pattern to be projected can be drawn first through design software. After the film, which is originally perpendicular to the optical axis of the projection component 30, is rotated 40°, the standard pattern is connected to the light-emitting point 3m away, and the lines connecting the points pass through the film (after rotating 40°) to form multiple intersections. These intersections are connected to obtain the anti-deformed film pattern (anti-deformation pattern).

[0066] Optionally, the projection assembly 30 is arranged in the shell assembly through an angle adjustment structure, and the actual angle between the projection assembly 30 and the projection surface can be adjusted during installation and maintenance. The film is arranged in the projection assembly 30 through a detachable structure. During specific installation, the angle of the projection assembly 30 is adjustable, so that the projection angle can be adaptively adjusted according to the on-site environment. For example, when the installation position of the lamp is not centered or flat, or when the walls on both sides of the lane have a certain inclination, the projection assembly 30 can be rotated in the left and right directions, so that the angle (angle) between the projection assembly 30 and the walls on both sides of the lane can be adjusted to an appropriate angle, so that the projected pattern is more standard, the adaptability to the environment is better, and the application effect is better. In specific applications, the projection assembly 30 can be rotatably connected to the inside of the lamp through a damping shaft structure.

[0067] Optionally, a film mounting ring 354 is disposed between the first single-sided convex lens 351 and the double-sided convex lens 352 , and the film sheet can be attached to the end surface of the film mounting ring 354 to facilitate the positioning of the film sheet.

[0068] like Fig.11As shown, the first single-sided convex lens 351, the film mounting ring 354, the double-sided convex lens 352, and the second single-sided convex lens 353 are coaxially arranged in sequence. The first single-sided convex lens 351 has a first step base and a first convex transparent portion away from the projection light source 32. The large end diameter D2 of the first base step can be 7.6-7.7 mm and the thickness T12 can be 0.6-0.8 mm, the small end diameter D1 can be 7.1-7.2 mm, the overall thickness T11 of the first base step can be 1.2-1.3 mm, and the overall thickness T10 of the first single-sided convex lens 351 can be 2.3 mm. The film mounting ring 354 is in a circular shape and the overall thickness T20 may be 0.5-0.6 mm, the outer diameter D4 may be 7.6-7.7 mm, and the inner diameter D3 may be 3.8-4.2 mm, and the distance S1 between the film mounting ring 354 and the circular base of the biconvex lens 352 may be 2.4-2.6 mm. The biconvex lens 352 has a circular base, and its diameter may be 8.4-8.6 mm.

[0070] Optionally, a slot (not shown) for inserting a film is provided on the side of the projection assembly 30. The slot can also be designed to allow the film and the film mounting ring 354 to be inserted, so as to facilitate the replacement of different films. Different films can be preset with different anti-deformation patterns. During production, the corresponding film (or: film and film mounting ring 354) can be inserted into the slot as needed, so as to meet the production of different models and series of products (for projecting different patterns).

[0071] Optionally, the projection ratio of the projection component 30 can be 0.5 to 0.7. In the present application, the projection ratio of the projection component 30 is 0.6, that is, when the projection distance is 3m, the size of the pattern (projection logo) is 1.8m. Take the following use environment conditions as an example: the lamp is installed at the top of a 3m high and 5m wide lane, and the pattern needs to be projected on the wall at a height of 1m from the ground, so the angle between the installation position of the projection component 30 and the ground normal is 50°, and the calculation formula is: Arctan (2.5 / 2) = 50°, the pattern on the film can be magnified to 480 times, and the pattern projected on the wall and the green light measured illuminance of the projection logo can reach at least 16.5lx, and the average illuminance of white light on the ground (10*5m) is ≥30lx, and the application effect is good.

[0072] Specifically, at least two positioning posts 321 are provided at the bottom of the projection lens assembly housing, and the projection light source 32 is provided on the projection substrate 33. The projection substrate 33 is provided with positioning holes 331 for the positioning posts 321 to be inserted. The positioning posts 321 may be in the shape of a cross column, which may be interference-fitted with the circular positioning holes 331 and is easy to install. During installation, the light shield 31 may be turned over first, and then the lens module may be installed on the light shield 31 as a whole, and then the projection substrate 33 with the output wires welded thereon may be aligned with the positioning posts 321 of the lens module and placed thereon. The positioning posts 321 of the lens module and the positioning holes 331 of the projection substrate 33 may be interference-fitted, and the projection substrate 33 may be kept in place. After the output wires are arranged, the cross positioning posts 321 designed on the projection lens assembly housing may be interference-fitted with the positioning holes 331. Turn the entire projection assembly 30 over. The light shield 31 can be provided with a snap-on structure 36. The snap-on structure 36 and the mounting position can be pre-assembled so that the projection assembly 30 contacts the light source mounting surface of the main shell 11. Arrange the wires and fix the projection assembly 30 with M4*14 stainless steel combination screws.

[0073] The present invention also provides a projection method of a lamp, using the above-mentioned lamp, comprising the following steps:

[0074] Install the lamp so that the projection assembly 30 of the lamp faces the projection surface at a set angle;

[0075] When the projection assembly 30 is working, the projection light of the projection light source 32 passes through the reverse deformation pattern of the film and projects a preset logo on the projection surface. When the projection assembly 30 is obliquely oriented toward the projection surface, the reverse deformation pattern is corrected, and under the condition of oblique projection, the preset logo shape projected on the projection surface is the required logo shape (such as a standard arrow shape), and the required preset logo shape can be obtained without projecting the projection assembly 30 directly onto the projection surface, so that the projection assembly 30 can be integrated into the lamp and installed above the lane, without the need for additional wiring on the wall and separate installation of the escape logo indicator light, and the lamp is easy to install and has low application cost.

[0076] Specifically, the projection assembly 30 can be rotated relative to the lamp body and fine-tuned to a desired angle so that the projected preset logo is more standard.

[0077] Specifically, the lamp can be installed in the lane, the projection surface is the longitudinal wall on both sides of the lane, and the light of the lighting assembly 30 is refracted through the lighting lens to the central area of ​​the lane isolated from the projected light, such as Fig.13 shown.

[0078] The lighting lens is used to make the angle between the luminous angle of the lighting component and the normal smaller than the angle between the projection component 30 and the normal, that is, the light emitted by the lighting component is refracted by the lighting lens and gathered toward the center (normal) of the lighting component, and the light emitted by the lighting component does not affect the projection light of the projection component 30 on the outside, so that the projection effect is guaranteed. Moreover, since the angle between the luminous angle of the lighting component and the normal is smaller than the angle between the projection component 30 and the normal, the brightness of the lighting component can be set to be higher, and the lamp can be used in alleys, etc. while taking into account both the lighting effect and the projection effect, and the application effect is good.

[0079] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modification, equivalent substitution or improvement made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
