Description

Technical Field

[0001] The present application relates to the technical field of lighting equipment, and in particular to an LED induction wall lamp that is easy to dissipate heat. Background Art

[0002] Wall lamps are a common lighting device in our daily life. Traditional wall lamps are turned on or off by contact switches, while existing wall lamps can be turned on or off automatically by non-contact means through factors such as sound and ambient light. Since wall lamps are mostly set on the sides of vertical walls, the walls will block the airflow, resulting in low air flow near the wall lamps next to the wall. In addition, the thermal conductivity of thick walls is relatively poor, and the heat dissipation efficiency of wall lamps in direct contact with the wall is low. Even if the heat generation rate of wall lamps using LEDs is not high, the temperature of the lamp body will still rise if powered for a long time, thus affecting the service life of the wall lamp. Summary of the invention

[0003] The purpose of the present application is to provide an LED induction wall lamp that is easier to dissipate heat.

[0004] In order to achieve the above objectives, the present application provides an easy-to-dissipate heat LED induction wall lamp: comprising a back panel and a lamp body, the front of the back panel is provided with a guide groove extending downward from the upper surface, the front of the lamp body is provided with a light-emitting panel and a sensor, the back of the lamp body is fixedly connected with a plurality of parallel heat dissipation plates, convection grooves are formed between the magnetic suction plates, the rear side surfaces of the heat dissipation plates are jointly fixedly connected with a guide plate, which is suitable for being inserted into the guide groove to form a sliding pair, thereby facilitating the disassembly and assembly of the lamp body and the back panel.

[0005] As a preference, the guide groove and the guide plate both extend in the vertical direction, and the cross-sections of the guide groove and the guide plate are both T-shaped, so as to prevent the guide plate from slipping out of the guide groove under non-manual operation conditions.

[0006] As a preferred embodiment, there are two sensors, and both sensors are located below the lamp body, so that the two sensors can be relatively close to the ground.

[0007] As a preferred embodiment, the two sensors are at the same level, and both sensors use infrared sensors to sense the movement of the human body, thereby realizing non-contact induction switch operation.

[0008] As a preference, all of the heat dissipation plates extend in a horizontal direction, and the distances between the heat dissipation plates are equal, which is conducive to uniform heat dissipation.

[0009] As a preference, an upper cover is further provided on the top of the back plate and the lamp body, which is suitable for covering the gap between the lamp body and the back plate to prevent dust from affecting the smoothness of the disassembly and assembly operations.

[0010] As a preferred embodiment, a limiting groove is provided on the top surface of the back panel, and a limiting block is provided on the back surface of the upper cover, which is suitable for fitting into the limiting groove; a magnetic sheet is fixedly connected to the top surface of the lamp body, and a metal sheet is fixedly connected to the bottom surface of the upper cover, which is suitable for being adsorbed by the magnetic sheet, thereby ensuring the installation stability of the upper cover and facilitating disassembly and assembly.

[0011] Preferably, a wiring terminal is provided on the back of the lamp body, and the back panel is provided with a lead hole running through the front and rear sides, suitable for aligning with the wiring terminal; the back panel is also provided with a mounting hole running through the front and rear sides, for fixing the entire wall lamp on the wall.

[0012] Compared with the prior art, the beneficial effects of this application are:

[0013] (1) By arranging a horizontal heat sink on the back of the lamp body, forming a convection groove between the heat sinks to allow airflow to pass through, and using a back plate to separate the main heat-generating components from the wall, the contact area between the airflow and the outer surface of the wall lamp is larger and the fluidity is better, so that the entire wall lamp is easier to dissipate heat, and the time required for heating is longer, which is conducive to extending the service life of the internal working components of the wall lamp;

[0014] (2) By providing a plug-in structure between the lamp body and the back panel, disassembly and assembly operations can be easily performed, which reduces the cost of maintenance and replacement. At the same time, a wiring terminal shielded by the back panel is provided on the back of the lamp body, which can not only reduce the probability of leakage, but also keep the appearance of the entire wall lamp flat and have good aesthetics.

DETAILED DESCRIPTION

[0022] Below, the present application is further described in conjunction with specific implementation methods. It should be noted that, under the premise of no conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments.

[0023] In the description of the present application, it should be noted that directional words, such as the terms "center", "lateral", "longitudinal", "length", "width", "thickness", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", "clockwise", "counterclockwise", etc., indicating directions and positional relationships are based on the directions or positional relationships shown in the accompanying drawings, which are only for the convenience of narrating the present application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and cannot be understood as limiting the specific scope of protection of the present application.

[0024] It should be noted that the terms "first", "second", etc. in the description and claims of the present application are used to distinguish similar objects, and are not necessarily used to describe a specific order or sequence.

[0025] The terms "including" and "having" and any variations thereof in the specification and claims of this application are intended to cover non-exclusive inclusions. For example, a process, method, system, product or apparatus comprising a series of steps or units is not necessarily limited to those steps or units explicitly listed, but may include other steps or units not explicitly listed or inherent to these processes, methods, products or apparatuses.

[0026] like Figure 1-6The easy-to-dissipate heat LED induction wall lamp shown includes a back panel 1 that needs to be fixedly installed, and a lamp body 2 is plugged into the front of the back panel 1. In order to achieve the plug-in, a guide groove 102 extending from the upper surface downward is opened on the front of the back panel 1. The guide groove 102 does not pass through the bottom surface of the back panel 1. A terminal 207 is set on the back of the lamp body 2 for connecting the power cord. The back panel 1 is provided with a lead hole 101 that passes through the front and rear sides. After the lamp body 2 and the back panel 1 are plugged into place, it is just aligned with the terminal 207, so as to facilitate the power cord pre-buried in the wall to pass through and then connect with the terminal 207. The back panel 1 is also provided with an installation hole 103 that passes through the front and rear sides for expansion screws and other connectors to pass through and fix the back panel 1 on the wall and other installation surfaces.

[0027] A number of parallel heat sinks 203 are fixedly connected to the back of the lamp body 2. The heat sink 203 is made of an alloy with high thermal conductivity, such as aluminum alloy or copper alloy, and is used to directly contact the light-emitting panel 201 with LEDs. The two ends of the heat sink 203 are flush with the left and right sides of the outer shell of the lamp body 2, and can also enhance the appearance of the entire wall lamp. Convection grooves 204 are formed between the heat sinks 203, and air can pass through the convection grooves 204 to take away the heat from the surface of the heat sink 203. All the heat sinks 203 extend in a horizontal direction. Because most houses are permeable from north to south, the airflow through the room is mainly in a horizontal direction. There are fewer obstructions outdoors, and the airflow is more likely to flow in a horizontal direction. The spacing between the heat sinks 203 is equal, that is, the width of each convection groove 204 is equal, which is conducive to uniform heat dissipation.

[0028] The rear side of the heat sink 203 is fixedly connected with a guide plate 206. The guide groove 102 and the guide plate 206 extend in the vertical direction. The guide plate 206 is inserted into the guide groove 102 to form a sliding pair. The cross-sections of the guide groove 102 and the guide plate 206 are both T-shaped, which can effectively prevent the guide plate 206 from escaping from the side of the matching guide groove 102. The back plate 1 and the guide plate 206 are usually made of metal materials with good thermal conductivity.

[0029] A light-emitting panel 201 and a sensor 202 are provided on the front of the lamp body 2. The light-emitting panel 201 includes a reflector embedded in the outer shell of the lamp body 2. An LED light-emitting unit is provided on the front of the reflector. The light-emitting panel 201 also includes a transparent cover that is flush with the outer shell of the lamp body 2, which is used to protect the reflector and the LED light-emitting unit without affecting the light transmission of the LED light-emitting unit. There are usually two sensors 202, both of which are located below the lamp body 2 and at the same horizontal height. Both sensors 202 use infrared sensors and are connected to the controller inside the lamp body 2. When a human body passes over the two infrared sensors 202 within one second, the controller can change the power-on state of the LED light-emitting unit to achieve contactless opening and closing.

[0030] An upper cover 3 is also provided on the top of the back plate 1 and the lamp body 2, which can cover the gap between the lamp body 2 and the back plate 1 to prevent dust from entering the gap between the guide plate 206 and the guide groove 102, thereby affecting the comfort of the plugging and unplugging operation process. A limiting groove 104 is provided on the top surface of the back plate 1, and a limiting block 302 is provided on the back of the upper cover 3, which just fits with the limiting groove 104, so that the upper cover 3 can be placed on the lamp body 2 and move left and right; a magnetic suction piece 205 is fixedly connected to the top surface of the lamp body 2, and a metal sheet 301 is fixedly connected to the bottom surface of the upper cover 3, which can be adsorbed by the magnetic suction piece 205, thereby preventing the upper cover 3 from sliding back and forth on the upper surface of the lamp body 2, so that the upper cover 3 can be directly placed on the lamp body 2. It will have good stability. In fact, the upper cover 3 is a solid plastic block, and the upper surface of the upper cover 3 is aligned with the top surface of the back plate 1 when the lamp body 2 is fully fitted with the back plate 1, which can help the installer determine whether the wall lamp is fully installed.

[0031] Working principle: This wall lamp is not equipped with an active heat dissipation mechanism like a traditional wall lamp. Instead, a heat dissipation plate 203 structure with roughly the same direction as the airflow is set on the back of the lamp body 2. The convection grooves 204 between the heat dissipation plates 203 can pass the airflow, thereby efficiently carrying the heat generated by the wall lamp.

[0032] During installation, first pass the power cord through the lead hole 101 of the back panel 1, then use expansion bolts to fix the back panel 1 to the wall, connect the power cord to the terminal 207 on the back of the lamp body 2, and then plug the lamp body 2 into the front of the back panel 1. Finally, buckle the upper cover 3, press the guide plate 206 down to the bottom of the guide groove 102, and the installation is completed.

[0033] If the wall lamp is installed upward, when in use, the LED light can be turned on or off by waving the palm of the hand across the two sensors 202 within one second; if the wall lamp is installed close to the floor, when in use, the LED light can be turned on or off by waving the calf across the two sensors 202 within one second, that is, non-contact switching operation is achieved through induction; when the human body stops in front of the wall lamp, or moves at a very slow speed, the brightness state of the wall lamp will not change, effectively reducing the probability of misoperation.

[0034] The above describes the basic principles, main features and advantages of the present application. Those skilled in the art should understand that the present application is not limited by the above embodiments, and the above embodiments and the specification only describe the principles of the present application. The present application may have various changes and improvements without departing from the spirit and scope of the present application, and these changes and improvements fall within the scope of the present application for which protection is sought.
