[0021] The technical solution of the present application will be described clearly and completely below in conjunction with the embodiments. Obviously, the described embodiments are part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in the field without creative work are within the scope of protection of the present application.

[0022] Evacuation emergency lighting and sign lights are collectively referred to as emergency lighting fixtures. Emergency lighting is an emergency lighting tool that maintains lighting and guides evacuation in emergency situations. Handheld emergency lighting equipment is an important product in safety measures. It can provide lighting like ordinary lamps, and can also provide emergency lighting in emergencies. For example, when an earthquake, fire or circuit failure causes a sudden situation, causing all light sources to stop working, the equipment must immediately provide reliable lighting so that the trapped people can find the direction of evacuation and the location of the emergency exit in the enclosed space, so as to ensure that the people stranded in the dark can evacuate smoothly or be quickly found and guided to escape.

[0023] Emergency lighting is used in emergencies, and most emergencies will produce smoke of varying sizes. However, existing common lighting equipment has a low ability to penetrate smoke and cannot meet the needs of emergency lighting in emergencies. It can be seen that in emergencies, it is critical to have a portable lighting device that can both illuminate and penetrate smoke. Since the green light beam has a stronger effect on smoke penetration than white light, green light and white light are integrated. White light is mainly used for lighting, while green light can penetrate smoke and is easier to be found, so as to achieve the purpose of calling for help or serving as a safety guide.

[0024] Therefore, the present application embodiment provides a handheld emergency lamp, such as Figure 1-3As shown, it includes: a lamp body 1 and a dual-light lighting system fixedly arranged at the end of the lamp body 1; the dual-light lighting system includes a shell, and a first lighting component and a second lighting component arranged in the shell, the first lighting component is fixed on the shell, and the second lighting component is fixed on the first lighting component; the first lighting component and the second lighting component divide the interior of the shell into a lighting space 2 and a penetrating light space 3, and the light in the lighting space 2 and the light in the penetrating light space 3 are not mixed in the shell.

[0025] Specifically, the lamp body 1 is the handheld part of the emergency lamp, and a dual-light lighting system is fixedly arranged at the end of the lamp body 1, and the dual-light lighting system is used for lighting. The user can hold the lamp body 1 for emergency lighting.

[0026] The dual-light illumination system includes two different light source components, namely a first illumination component and a second illumination component, which are arranged in a housing. The housing has a light transmission function, such as a transparent housing, which has good light transmission capability for the dual-light illumination system and provides protection for the dual-light system.

[0027] The first lighting assembly is fixed on the housing, and the second lighting assembly is fixed on the first lighting assembly. The first lighting assembly and the second lighting assembly divide the interior of the housing into a lighting space 2 and a penetrating light space 3. The light in the lighting space 2 and the light in the penetrating light space 3 are not mixed in the housing. The purpose is to make the lights emitted by the dual light system not affect each other, thereby avoiding the phenomenon that the penetrating effect or lighting effect is reduced after the light is mixed.

[0028] Compared with the prior art, the embodiment of the present application responds to the needs of emergency lighting by setting up a dual-light lighting system. The dual-light lighting system includes two different lighting components. The first lighting component has the characteristic of strong penetration, and the second lighting component has the characteristic of range lighting. The combination of the two can simultaneously meet the needs of range lighting and penetration lighting. The first lighting component and the second lighting component divide the interior of the shell into a lighting space 2 and a penetration light space 3. The light in the lighting space 2 and the light in the penetration light space 3 are not mixed in the shell. Therefore, it can be avoided that the penetration light has a poor penetration effect after the light is mixed. It can effectively solve the technical problem in the prior art that ordinary lighting equipment has poor penetration into smoke, which directly affects the emergency lighting effect and cannot meet the emergency lighting needs in smoke-prone scenes.

[0029] In one embodiment, the housing includes a base 8 and a transparent protective cover 9, and the transparent protective cover 9 is detachably connected to the base 8. The housing of the dual-light lighting system is configured as a detachable connection structure to facilitate replacement and maintenance of the first lighting assembly and the second lighting assembly.

[0030] The base 8 is a hollow structure, in which a control board 10 is disposed, and the first lighting assembly and the second lighting assembly are electrically connected to the control board 10. The control board 10 can control the first lighting assembly and the second lighting assembly, and can turn on, turn off, or turn on and off the first lighting assembly and the second lighting assembly at the same time according to the needs of the actual application scenario.

[0031] It is understandable that in a scene without smoke, only the second lighting component can be turned on for range lighting, and in a scene with smoke, the first lighting component can be turned on to provide light with strong penetrating power. The first lighting component and the second lighting component can also be turned on at the same time to meet both the requirements of penetrating power and the requirements of range lighting.

[0032] In a specific embodiment, the first lighting assembly includes a green light base 11, a green light LED lamp bead 12 and a green light laser light source 13, and the green light LED lamp bead 12 and the green light laser light source 13 are both fixedly arranged on the green light base 11; the green light base 11 is fixed on the base 8.

[0033] The green light base 11 can be set in a cylindrical shape or a polyhedron shape. In this embodiment, the green light base 11 is set in the form of a polyhedron column, which is convenient for the installation of the green light LED lamp bead 12 and the green light laser light source 13. One green light LED lamp bead 12 and one green light laser light source 13 can be installed on one surface. A green light LED lamp bead 12 and a green light laser light source 13 installed on the same surface are called a pair of green light sources.

[0034] There are multiple green LED lamp beads 12 and green laser light sources 13, which surround the outer surface of the green base 11 respectively; the green LED lamp beads 12 and green laser light sources 13 are arranged in pairs.

[0035] The second lighting assembly includes a white light LED lamp bead 14 and a curved reflective bowl 15 . The white light LED lamp bead 14 is fixed to the end of the green light base 11 . The curved reflective bowl 15 is covered outside the white light LED lamp bead 14 . The curved reflective bowl 15 abuts against the transparent protective cover 9 .

[0036] In this embodiment, the first lighting component uses green light illumination, and the second lighting component uses white light illumination. The second lighting component is mainly composed of a single LED lamp bead and a curved reflective bowl 15. Since the white light LED lamp bead 14 is divergent, the curved reflective bowl 15 is used to shape the light beam, and the angle of the light beam at the center and edge of the lamp bead is realized to realize partial light beam convergence, but part of the light does not reach the surface of the curved reflector and will directly irradiate into the space, so that the white lighting beam has high central brightness and a large irradiation range. The first lighting component is installed on the side, and it uses a green laser light source 13 and an LED light source. Since the laser light source has a small angle collimation effect, it has a strong ability to penetrate smoke, but it cannot have range illumination. Therefore, it cooperates with the green light LED to realize range illumination. The combination of the two solutions improves the ability of green light to penetrate smoke while ensuring range illumination, that is, it realizes the penetration of smoke and achieves short-distance range coverage, which not only realizes the high energy of the central light beam of the lighting beam but also avoids a small beam angle.

[0037] The control panel 10 is mainly used for control functions, realizing dual-light working mode switching and system lighting functions, and specifically can realize the second lighting component working alone or the first lighting component working alone, or dual lights working simultaneously.

[0038] The shell serves as a transparent protective cover to protect the internal lighting optical system, preventing external dust from polluting the dual-light lighting system, and is fixedly installed and connected to the main body to play a protective role.

[0039] In one embodiment, an annular groove 16 is provided at the connection between the dual-light lighting system and the lamp body 1 for heat dissipation.

[0040] In one embodiment, the lamp body 1 includes a hand-held rod 4, one end of which is fixedly connected to a base 8, and the other end of the hand-held rod 4 is provided with a control button 5, and the control button 5 is electrically connected to a control panel 10. The lamp body 1 also includes a built-in power supply 6, which is arranged inside the hand-held rod 4. A battery compartment 7 is arranged on the hand-held rod 4, and a built-in battery is arranged in the battery compartment 7; the outer surface of the battery compartment 7 is a polyhedron.

[0041] It can be seen that the characteristic of the lamp body 1 is that the top of the lighting system is installed in a "concave" groove form to provide mechanical protection impact design for the top. When the external protective shell is broken or falls, it can protect the luminous lighting unit to the greatest extent. At the same time, a stepped transition form is adopted at the front end and the middle part of the main body, which is convenient for installation and fixation and can accelerate the internal heat dissipation. The polygonal form is adopted in the middle to avoid the problem of no rolling resistance of the cylindrical form. The main body material can adopt explosion-proof metal material, so as to meet the waterproof, drop-resistant and heat-resistant characteristics of emergency lighting.

[0042] The built-in battery is located in the lamp body 1 installed with a fixed frame. The fixed frame can be set according to the shape and size of the built-in battery, and is used to fix the built-in battery so that the built-in battery is installed inside the lamp body 1 stably and firmly without moving, and the safety of the internal battery can be ensured. The internal built-in battery mainly realizes the power supply function for the lighting system. At the same time, this patent adopts a rechargeable form, and the battery is repeatedly used. The key switch is installed under the lamp body 1 to open and close and instruct the control panel 10.

[0043] Cables are arranged in the hollow lamp body 1, and the cables connect the control button 5, the internal battery, the control board 10 and the dual-light lighting system to realize the power supply and control functions of the dual-light lighting system.

[0044] In a more specific embodiment, the front end of the lamp body 1 is a dual-light lighting system. A shell with a protective and light-transmitting function is installed on the outside of the dual-light lighting system and is fixedly connected to the head of the lamp body 1. The dual-light lighting system is composed of a white light system and a green light system. The curved reflective bowl 15 inside the shell is installed at the front end of the light-emitting surface of the white light LED lamp bead 14, and its overall light output direction is the forward illumination of the lamp. There are two types of green light sources on the side of the dual-light lighting system, namely green light LED lamp bead 12 and green light laser light source 13. The divergence angle of the green light LED lamp bead 12 is large and the divergence angle of the green light laser light source 13 is small, realizing an upper and lower combination arrangement. At the same time, the overall multi-faceted distribution structure can realize the illumination of the light beam in multiple directions, such as Figure 3 The light beam irradiation direction of the dual light system is displayed. A control panel 10 is installed at the rear end of the dual light lighting system. The control panel 10 is connected to the built-in power supply 6, white light LED lamp beads 14, green light LED lamp beads 12 and green light laser light source 13 through wires. The control button 5 is connected below the control panel 10. The control button 5 is used in combination with the control panel 10 and the built-in power supply 6 to form a control unit of the system. The control panel 10 can change the lighting mode according to the form of a push switch, and the built-in power supply 6 is used as the power supply for the entire system. It has a charging storage power supply, and its charging port is installed on the bottom end face of the polygon in the middle of the lamp body.

[0045] like Figure 2The three-dimensional structure of the lamp is shown in the figure. The overall structure of the lamp body 1 is designed as a combination of a cylinder and a polygon, and the top is a square. The structure of the dual-light lighting system installed on the top shows a "concave" wall-like structural design, which is mainly used to increase the impact protection of the lighting system. The link at the top is in the form of a step transition, which is mainly to expand the external contact area and increase the heat dissipation efficiency of the optical system. At the same time, the structure has a stepped axis that facilitates the installation of fixed points. The overall center of gravity of this product is in the area where the built-in power supply 6 is placed on the main body, and the middle area of ​​the main body presents a polygonal structural design, which can reduce the number of times the lamp falls to the ground and rolls.

[0046] like Figure 3 The figure shows the working principle of the dual-light lighting system. The dual-light lighting system is mainly composed of white and green light. The first lighting component is the green light lighting system, and the second lighting component is the white light lighting system. The green light lighting system is composed of green LED lamp beads 12 and green laser light sources 13. The green LED lamp beads 12 of the green light lighting system present a lighting form with a large dispersion angle, while the green laser light source 13 presents a small-angle direct beam. The main function of the two beams is to ensure the penetration of smoke while providing range lighting. This patent uses the divergent characteristics of the green LED lamp beads 12 to achieve range lighting. At the same time, the small angle of the green laser light source 13 can achieve a stronger penetration ability of the smoke, so that it can meet the needs of long-distance lighting in the smoke. The combination of the two forms can achieve rapid guidance and easier discovery in dark environments and smoke environments.

[0047] like Figure 3 The white light lighting system shown is composed of a curved reflective bowl 15 and a white light LED lamp bead 14. The light beam is displayed as a dense middle light beam, and the edge light beam diverges and returns through the curved reflective bowl 15 to converge with the center light beam and emit directly. A single white light LED lamp bead 14 and a curved reflective bowl 15 form a white light lighting system. Since the light beam emitted by the white light LED lamp bead 14 is divergent, the curved reflective bowl 15 is used to shape the divergent light beam, and the central part and the edge light beam of the white light LED lamp bead 14 are converged. At the same time, due to the limited height of the curved reflective bowl 15, part of the light on the emitting surface of the white light LED lamp bead 14 does not reach the surface of the curved reflector, and will directly irradiate into the space. The final lighting spot distribution is displayed as a white lighting beam with high brightness in the center and a certain irradiation range, which satisfies the functions of realizing high-brightness lighting and range lighting.

[0048] The handheld emergency lamp provided in the embodiment of the present application can realize convergent lighting and smoke-penetrating lighting through a dual-light lighting system, and the dual-light systems are a white light lighting system and a green light lighting system. The white light lighting system is mainly composed of a single LED lamp bead and a curved reflective bowl 15. Since the white light LED lamp bead 14 is divergent, the curved reflective bowl 15 is used to shape the light beam, and the angle of the light beam at the center and edge of the lamp bead is realized to realize partial light beam convergence, but part of the light does not reach the surface of the curved reflector and will directly irradiate into the space, so that the white lighting beam center brightness is high and the irradiation range is large. The green light lighting system is installed on the side, and it uses a green laser light source 13 and an LED light source. Since the laser light source has a small angle collimation effect, it has a strong ability to penetrate smoke, but it cannot have range lighting. Therefore, it cooperates with the green light LED to realize range lighting. The combination of the two solutions improves the ability of green light to penetrate smoke and ensures range lighting at the same time, that is, it realizes the penetration of smoke and also realizes short-distance range coverage, which not only realizes the high energy of the central light beam of the lighting beam but also avoids the small beam angle. Green light and white light are integrated into one product. White light is mainly used for lighting, while green light can penetrate smoke to make it easier to be discovered, to call for help or as a safety guide.
