Description

Technical Field

[0001] This utility model relates to the field of lighting device technology, and in particular discloses a bidirectional side-emitting lamp. Background Technology

[0002] Existing side-emitting luminaires are typically designed to emit light in a single direction, such as emitting light from only one side of the luminaire. This structure has significant limitations in scenarios requiring simultaneous illumination of two sides of a space, such as corridors, cabinets, display cases, or workbenches. Often, two sets of luminaires, placed back-to-back, are needed to achieve bidirectional lighting. This not only increases installation complexity and cost but also leads to cumbersome wiring, large space requirements, and an unsightly appearance. Furthermore, traditional luminaires struggle to achieve independent control and differentiated lighting effects on both sides within a single structure, limiting their application flexibility. Utility Model Content

[0003] In order to overcome the obvious limitations of existing lamps with a single light output direction in scenarios where both sides of the space need to be illuminated simultaneously, the purpose of this utility model is to provide a bidirectional light-emitting lamp that can achieve independent light output from both sides.

[0004] To achieve the above objectives, this utility model provides a bidirectional side-emitting lamp, comprising a lamp housing and a light source disposed on the lamp housing; the lamp housing has a main housing and two side walls intersecting the main housing, the two side walls being located on opposite sides of the main housing respectively, the first side wall having a first light-emitting hole, and the second side wall having a second light-emitting hole, the light source comprising a first light strip located in the first light-emitting hole and a second light strip located in the second light-emitting hole; the light emitted by the first light strip is emitted to the outside through the first light-emitting hole, and the light emitted by the second light strip is emitted to the outside through the second light-emitting hole.

[0005] Furthermore, the bidirectional side-emitting lamp also includes a first light-transmitting plate covering the first light-emitting hole and a second light-transmitting plate covering the second light-emitting hole. The light emitted by the first lamp bar is sequentially irradiated to the outside through the first light-emitting hole and the first light-transmitting plate, and the light emitted by the second lamp bar is sequentially irradiated to the outside through the second light-emitting hole and the second light-transmitting plate.

[0006] Furthermore, the light-transmitting area of ​​the first light-transmitting plate accounts for 1 / 10 to 2 / 3 of the total area of ​​the first sidewall of the lamp housing, and the light-transmitting area of ​​the second light-transmitting plate accounts for 1 / 10 to 2 / 3 of the total area of ​​the second sidewall of the lamp housing.

[0007] Furthermore, the bidirectional side-emitting lamp also includes two reflective papers. The first reflective paper is disposed in the first light-emitting hole to concentrate and reflect the light emitted by the first light strip to the first light-transmitting plate. The reflective surface of the first reflective paper and the mounting surface of the first light strip are provided with a first angle of 45-120°. The second reflective paper is disposed in the second light-emitting hole to concentrate and reflect the light emitted by the second light strip to the second light-transmitting plate. The reflective surface of the second reflective paper and the mounting surface of the second light strip are provided with a second angle of 45-120°.

[0008] Furthermore, the first light strip includes a first light panel, a plurality of first light beads and a plurality of second light beads disposed on the first light panel, wherein the power of the first light beads is greater than the power of the second light beads, the light emitted by the first light beads is used for illumination, and the light emitted by the second light beads is soft light and / or colored light.

[0009] Furthermore, a mounting cavity is provided between the first light-emitting hole and the second light-emitting hole of the lamp housing, and a first isolation member and a second isolation member are provided on the lamp housing. The first isolation member is used to isolate the first light-emitting hole and the mounting cavity, and the second isolation member is used to isolate the second light-emitting hole and the mounting cavity.

[0010] Furthermore, the bidirectional side-emitting lamp also includes a power supply unit and a control unit disposed in the mounting cavity and electrically connected to the light source. The power supply unit is used to be electrically connected to an external power supply via an external wire, or the power supply unit is a rechargeable battery disposed on the lamp housing and a charging interface used in conjunction with the rechargeable battery. The control unit includes a control circuit board and a switch module, and the switch module controls the light source to turn on or off via the control circuit board.

[0011] Furthermore, the control unit also includes a mode adjustment module electrically connected to the control circuit board. The mode adjustment module is one or more combinations of a sliding adjustment key, a touch adjustment key, and a sensor adjustment key. The mode adjustment module controls the first and / or second light strips of the light source to emit light via the control circuit board.

[0012] Furthermore, a first cover and a second cover are detachably provided at both ends of the lamp housing along its length. The light source, power supply unit, and control unit are respectively inserted into the lamp housing along its length. The first cover and the second cover are used to encapsulate the light source, power supply unit, and control unit inside the lamp housing.

[0013] Furthermore, the lamp housing is provided with a magnetic attraction unit, which includes a magnetic component and a shielding cover. The shielding cover is fitted over the outside of the magnetic component, allowing only one end face of the magnetic component to be exposed to the outside. The lamp housing is attracted to an external magnetically conductive object via the exposed end face of the magnetic component.

[0014] The core technical solution of this utility model lies in providing a bidirectional side-emitting lamp. It features two side walls intersecting on both sides of the main housing, with a first light-emitting hole and a second light-emitting hole respectively on each side wall. Independent first and second light strips are built into the main housing, allowing light to shine outwards from both sides. Specifically, by covering the first and second light-emitting holes with light-transmitting plates and placing reflective paper at a specific angle inside the light-emitting holes, the light emitted by the light strips is efficiently concentrated and guided to the light-transmitting surface, optimizing light output efficiency and uniformity. The light strips employ a combination design including LEDs of different power and color temperatures. Combined with a control unit located in the mounting cavity in the middle of the lamp housing, independent control of the lighting modes on both sides can be achieved, including switching, dimming, and color temperature switching. The internal components are encapsulated by removable covers at both ends of the lamp housing, and magnetic units are integrated for easy installation and maintenance.

[0015] The beneficial effects of this invention are as follows: First, the unique bidirectional side-emitting structure allows a single lamp to meet the simultaneous lighting needs of two spaces, significantly simplifying the installation process and reducing overall costs. Second, the combination of a reflective structure and independent control of dual light strips ensures uniform and soft light output while providing flexible, scenario-based lighting solutions, such as providing high-brightness main lighting on one side and low-brightness ambient lighting on the other. Finally, the modular cavity design and magnetic installation method enhance the product's practicality and adaptability, enabling rapid deployment and stable fixation in various installation environments.

Detailed Implementation

[0027] To facilitate understanding by those skilled in the art, the present invention will be further described below with reference to embodiments and accompanying drawings. The content mentioned in the embodiments is not intended to limit the present invention.

[0028] Please see Figures 1 to 9 As shown, this utility model discloses a bidirectional side-emitting lamp, comprising a lamp housing 1 and a light source 2 disposed on the lamp housing 1. The lamp housing 1 includes a main housing 11 and a first side wall 12 and a second side wall 12 intersecting the main housing 11, with the first side wall 12 and the second side wall 12 located on opposite sides of the main housing 11. The lamp housing 1 can be constructed by extrusion molding of aluminum alloy profiles or injection molding of engineering plastics, and its interior is formed into an integral hollow cavity by a first spacer 17 and a second spacer 18, facilitating the installation of the circuit board and the light source 2.

[0029] Specifically, a first light-emitting hole 13 is provided on the first sidewall 12, and a second light-emitting hole 14 is provided on the second sidewall 12. The first light-emitting hole 13 and the second light-emitting hole 14 are arranged opposite to each other to achieve independent light emission from both sides of the lamp. The light source 2 includes a first light strip 21 and a second light strip 22 respectively installed inside the two light-emitting holes. Both extend along the length of the lamp housing 1 and are arranged parallel to the inner wall of the main housing 11. The light strips are fixed by slots and form a thermally conductive contact surface with the lamp housing 1 to ensure heat dissipation performance when the LEDs heat up. The light from the first light strip 21 shines to the outside through the first light-emitting hole 13, and the light from the second light strip 22 shines to the outside through the second light-emitting hole 14, thereby achieving the effect of independent light emission from both sides of the lamp.

[0030] Specifically, to achieve dustproofing, anti-glare, and light equalization, the luminaire includes a first light-transmitting plate 15 covering the first light-emitting hole 13 and a second light-transmitting plate 16 covering the second light-emitting hole 14. Both light-transmitting plates can be made of acrylic or polycarbonate materials, possessing high light transmittance and impact resistance. The light-transmitting plates are fixed to the lamp housing 1 by a slot or thread structure. During installation, the edge of one side of the light-transmitting plate is first inserted into the corresponding slot in the housing wall, and then the other side is pressed together to form a tight fixation.

[0031] When the light is emitted, the light emitted by the first light strip 21 shines into the outside world through the first light outlet 13 and the first light-transmitting plate 15 in sequence, and the light emitted by the second light strip 22 also shines out through the second light outlet 14 and the second light-transmitting plate 16, so that both sides of the lamp can achieve a soft and uniform lighting effect.

[0032] The light-transmitting area of ​​the first light-transmitting plate 15 accounts for 1 / 10 to 2 / 3 of the total area of ​​the first sidewall, and the light-transmitting area of ​​the second light-transmitting plate 16 accounts for 1 / 10 to 2 / 3 of the total area of ​​the second sidewall. By controlling the proportion of the light-transmitting area, different ratios of brightness and illumination angle can be achieved according to lighting requirements.

[0033] In the first embodiment, the light-transmitting area of ​​the first light-transmitting plate 15 accounts for 2 / 3 of the total area of ​​the first sidewall 12, and the first light-transmitting plate 15 is arranged in an arc-shaped plate. Correspondingly, the light-transmitting area of ​​the second light-transmitting plate 16 accounts for 2 / 3 of the total area of ​​the second sidewall 12, and the structure of the second light-transmitting plate 16 is the same as that of the first light-transmitting plate 15.

[0034] In this embodiment, the first light-transmitting plate 15 has a first slot 151 and a first protrusion 152 on both sides along its length. The opening of the first sidewall 12 has a second slot 121 for accommodating the first protrusion 152 and a second protrusion 122 for extending into the first slot 151 on both sides. This locking mechanism allows the first light-transmitting plate 15 to be inserted along its length into the first sidewall 12 of the lamp housing 1, preventing it from moving along the thickness direction of the lamp housing 1. Similarly, the second light-transmitting plate 16 and the second sidewall 12 are fixed using the same structure.

[0035] In the second embodiment, the light-transmitting area of ​​the first light-transmitting plate 15 accounts for 1 / 2 of the total area of ​​the first sidewall 12. The first light-transmitting plate 15 is generally arranged in a flat strip shape. Correspondingly, the structure and shape of the second light-transmitting plate 16 are the same as those of the first light-transmitting plate 15.

[0036] In this embodiment, two first protrusions 152 are provided on both sides of the length direction of the first light-transmitting plate 15, and two second slots 121 are provided on both sides of the opening of the first sidewall 12. This structure allows the first light-transmitting plate 15 to be installed at the opening of the first sidewall 12. Similarly, the second light-transmitting plate 16 and the second sidewall 12 are fixed with the same structure.

[0037] In the third embodiment, the light-transmitting area of ​​the first light-transmitting plate 15 accounts for 1 / 2 of the total area of ​​the first sidewall 12, and the first light-transmitting plate 15 is in the shape of a flat strip. The light-transmitting area of ​​the second light-transmitting plate 16 accounts for 2 / 3 of the total area of ​​the second sidewall 12, and the second light-transmitting plate 16 is in the shape of an arc. The mounting structure of the first light-transmitting plate 15 and the first sidewall 12 corresponds to the second embodiment, and the mounting structure of the second light-transmitting plate 16 and the second sidewall 12 corresponds to the first embodiment.

[0038] Specifically, to improve light emission efficiency and light uniformity, reflective paper 3 is installed inside both light emission holes. The first reflective paper 3 is located inside the first lamp strip 21 to concentrate and reflect the scattered light emitted by it towards the direction of the first light-transmitting plate 15. The reflective surface of the first reflective paper 3 forms a first angle of 60° with the mounting surface of the first lamp strip 21 to ensure the concentration of reflected light and the uniformity of illumination.

[0039] A second reflective paper 3 is also installed inside the second light outlet 14, with its reflective surface forming a 60° angle with the mounting surface of the second light strip 22, thus ensuring relatively balanced light efficiency on both sides of the light-emitting structure. The reflective paper 3 can be made of PET reflective film or aluminum foil reflective layer, and is fixed to the inner wall of the lamp housing 1 by adhesive backing or snap-fit ​​structure. This structure can significantly reduce light loss and prevent glare.

[0040] Specifically, the first light strip 21 includes a first light panel 211, a plurality of first LED beads 212 and a plurality of second LED beads 213 mounted on the first light panel 211. The first LED beads 212 may be high-power white LEDs, used to provide the main lighting source; the second LED beads 213 may be low-power soft-light LEDs or colored LEDs, used to provide decorative or ambient light. The first LED beads 212 and the second LED beads 213 are arranged on the same light panel, which is fixed to the bottom surface of the lamp housing 1 or the heat sink substrate by screws.

[0041] The power differences between different LED chips allow the same lighting fixture to simultaneously provide both high-brightness illumination and soft lighting effects. By adjusting the operating current of the two types of LED chips through the control circuit, it is possible to achieve tiered brightness adjustment, color temperature variation, or unilateral light effect control.

[0042] Specifically, in the internal structure of the lamp housing 1, a mounting cavity 4 is formed between the first light-emitting hole 13 and the second light-emitting hole 14. This mounting cavity 4 is used to accommodate electrical components. A first isolation member 17 and a second isolation member 18 are respectively provided on both sides of the mounting cavity 4 to isolate the optical cavity from the electrical cavity, preventing light interference or dust from entering the circuit area. The isolation member can be a metal plate or an insulating plastic plate, which is fixed inside the lamp housing 1 by a slot and seals with the light-emitting cavity.

[0043] Specifically, a power supply unit and a control unit 6 are installed within the mounting cavity 4. The power supply unit can be a wire interface for connecting to an external power source, or a rechargeable lithium battery module installed inside the lamp housing 1. If battery power is used, a matching charging interface 52 is provided on the outer wall of the lamp housing 1, which can be charged via magnetic attraction or USB. The control unit 6 includes a control circuit board 61 and a switch module 62. The control circuit board 61 is electrically connected to the first light strip 21 and the second light strip 22, and is used to control the switching and illumination modes of the light strips. The switch module 62 can be a mechanical button, a touch button, or a human body sensor module. Electrical signals are transmitted to the light strips through the circuit board to control the lighting state.

[0044] Preferably, in this embodiment, the switch module 62 specifically includes a sliding physical switch 621 and an inductive infrared sensor switch 622.

[0045] To expand user adjustment functions, the control unit 6 also includes a mode adjustment module, which is electrically connected to the control circuit board 61. This module can be implemented using slide keys, touch keys, or sensor keys to achieve functions such as brightness adjustment, light color switching, or independent lighting of single or dual-sided light strips. The control circuit can preset multiple modes, such as single-sided illumination, dual-sided illumination, alternating flashing, or gradual light effects, allowing users to select according to their needs.

[0046] The lamp housing 1 has a first cover 7 and a second cover 8 at both ends, both of which can be detachably connected. The lamp strip, control unit 6, and power supply module can be inserted into the mounting cavity 4 along the length of the lamp housing 1, and then sealed by the end covers to form a complete and sealed strip lamp body structure. The covers and the main housing 11 can be connected by threads, snaps, or magnetic attraction, which ensures dustproof and waterproof performance and facilitates later maintenance and replacement.

[0047] To facilitate easy installation and disassembly, a magnetic unit 9 is provided on the outer surface of the lamp housing 1. The magnetic unit 9 includes a magnetic component 91 and a shielding cover 92. The magnetic component 91 is embedded in the outer wall of the lamp housing 1, and the shielding cover 92 covers its outer side, exposing only one end face of the magnetic component 91. During installation, the lamp housing 1 can be attracted to a metal bracket, iron plate, or other magnetically conductive mounting surface via the exposed end face of the magnetic component 91, allowing for quick and easy fixation without screws or brackets. The shielding cover 92 limits the range of magnetic force, preventing magnetic interference to the internal circuitry of the lamp body. This installation method allows for the rapid placement and movement of the lamp in various scenarios such as cabinets, walls, and exhibition stands.

[0048] The working principle of this utility model is explained below in conjunction with the above embodiments: When the lamp is powered on, the control circuit provides independent driving current to the first lamp strip 21 and the second lamp strip 22. The light is reflected through the light-emitting hole and the reflective paper 3 and shines to the outside through the light-transmitting plate. Users can select working modes such as simultaneous illumination from both sides, main lighting on one side, ambient lighting on one side, or alternating dual colors through the mode adjustment module (for example, both sides are ambient lighting, or both sides are illuminated with strong light), to achieve diversified lighting effects. By optimizing the angle of the reflective paper 3 and matching the area ratio of the light-transmitting plate, the lamp can achieve high luminous efficiency, low glare, and bidirectional uniform lighting effects with a limited thickness.

[0049] The above description is only a preferred embodiment of this utility model. For those skilled in the art, there will be changes in the specific implementation method and application scope based on the idea of ​​this utility model. The content of this specification should not be construed as a limitation of this utility model.
