AI Technical Summary
Existing LED lights have poor sealing in humid environments because the switch assembly is installed on the housing opening, allowing external moisture to easily enter the housing.
The design employs a combination of magnetic elements and Hall sensors to transmit control signals through the sidewalls of the housing, preventing moisture from entering while simultaneously adjusting optical or electrical properties, such as color temperature, beam angle, and brightness.
This allows for the adjustment of the optical and electrical characteristics of LED lights while maintaining their airtightness, thus improving the lights' waterproof performance and reliability.

Abstract
Description
Technical Field
[0001] This application relates to a lighting device, particularly a lamp, and more particularly to an LED lamp. Background Technology
[0002] Adjustable LED lights, such as LED lights with variable beam angle, LED lights with selectable color temperature (CCT), or LED lights with variable output brightness, use switching components such as DIP switches (Dual In-line Package switches, also known as toggle switches) mounted on the lamp housing to adjust the beam angle, color temperature changes, or voltage or current load on the LED light source.
[0003] However, the switch assembly is mounted on an opening in the housing. This opening is a weak point in terms of waterproofing, especially in humid environments, where external moisture can easily enter the lamp's housing. Therefore, existing lamps have a technical problem where sealing needs improvement. Utility Model Content
[0004] The purpose of this application is to solve the above-mentioned problems, which is to install a switch on the housing of the LED light, while ensuring that the location of the switch is waterproof.
[0005] Based on the above understanding, this application provides a lamp, comprising: a housing, a light source disposed inside the housing, a lamp head at one end of the housing, and a light-emitting window at the other end; the side wall of the housing between the lamp head and the light-emitting window is closed, without any openings or gaps penetrating the housing; a switch is disposed on the side wall of the housing, the switch containing a magnetic element, and a Hall sensor is disposed inside the housing at a position corresponding to the switch; displacement of the switch causes displacement of the magnetic element; this displacement is used to trigger a response of the Hall sensor to generate a control signal; the lamp also includes a controller for receiving the response signal of the Hall sensor to change the optical or electrical settings of the lamp. Because the side wall of the housing is closed, moisture cannot enter, while the magnetic field signal can be transmitted unimpeded through the side wall of the housing. Of course, the side wall of the housing, at least near the switch position, is made of a magnetically permeable material (e.g., plastic), and cannot be made of a magnetically blocking material.
[0006] The "switch" involved in this application does not only refer to a device that realizes the two states of "on" or "off", but refers to an element that changes the working state of the internal circuit of the lamp under the action of a Hall sensor through external manual intervention such as flicking, plugging or pressing, which ultimately causes changes in the optical or electrical characteristics of the lamp, such as changing color, changing color temperature, adjusting the dimming angle, changing brightness, etc.
[0007] Preferably, the switch includes a switch cap and the magnetic element housed within the switch cap.
[0008] In one embodiment, a sliding groove is provided on the side wall of the housing, which is isolated from the interior of the housing, and the switch is disposed in the sliding groove to slide.
[0009] Preferably, a circuit board is provided inside the housing, and the Hall sensor is disposed on the circuit board, facing the magnetic element across the side wall of the housing. Further, the circuit board is parallel to the sliding groove, and the projection of the Hall sensor in the sliding groove falls within the travel range of the magnetic element.
[0010] One Hall sensor can be installed in the lamp; the magnetic element triggers the control signal by approaching and moving away from the Hall sensor relative to it. Multiple Hall sensors can also be installed in the lamp; various combinations of the magnetic element approaching and moving away from each of the multiple Hall sensors generate various control signals.
[0011] In one embodiment, pressing the switch causes the magnetic element to approach and move away from the Hall sensor relative to it along the normal direction of the housing sidewall. In another embodiment, the approach and movement of the magnetic element relative to the Hall sensor is a lateral movement along the housing sidewall, perpendicular to the normal direction of the housing sidewall.
[0012] In some embodiments, the light source is a plurality of LEDs with different color temperatures. The brightness of the different LEDs is controlled according to the control signal, thereby changing the color temperature of the light output by the entire lamp.
[0013] In other embodiments, the light source is a plurality of LEDs, each with a lens having a different output beam angle. The brightness of the different LEDs is controlled according to the control signal, thereby changing the beam angle output from the entire lamp.
[0014] In some embodiments, the electrical parameters of the light source are controlled by the control signal, such as current or voltage control, thereby causing a change in the light intensity output by the entire lamp.
[0015] These embodiments are not isolated control modes, and they can be arranged and combined. For example, the color temperature and light intensity of the output light can be controlled simultaneously, or the color temperature and light angle of the output light can be controlled simultaneously, and so on.
[0016] In another embodiment, the housing sidewall may have several separate recesses into which the switch can be inserted. Alternatively, only one position may be provided to receive the switch, at which point pressing of the switch, in conjunction with the Hall sensor, generates a trigger signal.
[0017] The lamps applicable to this application can be LED retrofit LED lamps, such as various bulbs, PAR lamps, GU-10, MR-16, etc. Attached Figure Description

[0026] Figure 1 A lamp 10 according to this application is shown, including a housing, the sidewall 20 of which is open only at both ends, respectively providing a lamp head 11 and a light-emitting window 13, and the interior is provided with a light source 15 (see Figure 4 The sidewall 20 body is a closed structure with no through openings or gaps.
[0027] Switch 30 is mounted on side wall 20. Figure 1 , 3 In embodiments 4, the side wall 20 is provided with a sliding groove 25 that is isolated from the inside of the housing, and the switch 30 is disposed in the sliding groove 25 to slide.
[0028] The switch 30 can be divided into a switch cap 31 and a magnetic element 33 housed therein. The magnetic element 33 can be, for example, a permanent magnet.
[0029] See Figure 4 In particular, the enlarged view shows a circuit board 23 inside the housing, with a Hall sensor 21 mounted on this circuit board 23, facing the switch 30 across the side wall 20. The circuit board 23 is parallel to the sliding groove 25. In the illustrated embodiment, there is only one Hall sensor 21, located in the middle of the projection of the sliding groove 25. Therefore, the sliding of the switch 30 can generate three signals: above, middle, and below. Of course, there can also be only two signals, namely approaching and moving away. A controller can also be mounted on the circuit board 23 to receive the signals generated by the Hall sensor and control the lamp. Of course, the controller can also be located in other positions of the lamp, such as near the light source, which will not be elaborated here.
[0030] exist Figure 2 In one embodiment, the sidewall 20 has separate recesses through which the switch 30 can be inserted and removed for control. Possible signal combinations include, for example, inserting three different signals generated by the switch 30 into the three recesses, or inserting two or three other signals generated by the switch 30 into the three recesses.
[0031] In other embodiments not shown, more than one Hall sensor 21 may be provided, such as two, and the positional relationship between the switch 30 and them can form other combinations of relationships to generate different control signals.
[0032] The controlled parameters of lamp 10 in this application include, but are not limited to, color temperature, color, beam angle, and light intensity, as well as combinations thereof. Taking an LED lamp with adjustable color temperature as an example, the light source 15 can be multiple LEDs with different color temperatures. According to the control signal sent by the Hall sensor 21, their brightness can be controlled separately, thereby realizing the color temperature adjustment of the output light of the entire lamp.
[0033] In the example of an adjustable beam angle LED lamp, the light source 15 can be multiple identical LEDs covered with lenses 17 of different output beam angles, or the light source 15 can be multiple LEDs with different output beam angles. According to the control signal sent by the Hall sensor 21, their brightness can be controlled separately, and the angle of the output light of the whole lamp can be adjusted.
[0034] The principle behind adjusting the headlight beam or a combination of the above adjustments is similar, so it will not be elaborated here.
[0035] While some specific embodiments of this application have been illustrated in detail by way of examples, those skilled in the art should understand that the above examples are intended to be exemplary only and not to limit the scope of this application. Those skilled in the art should understand that the above embodiments can be modified without departing from the scope and spirit of this application. The scope of this application is defined by the appended claims. In the specification and the following claims, unless the context otherwise requires, the terms "comprising" and "including" are understood to include the described ingredients or groups of ingredients, but do not exclude any other ingredients or groups of ingredients. Any references to prior art in this specification are not and should not be construed as an admission that such prior art constitutes common general knowledge.
