Description

Technical Field

[0001] This utility model relates to the field of sensor LED light technology, specifically a 15W microwave radar sensor LED light. Background Technology

[0002] LED lights, or light-emitting diodes, are solid-state semiconductor devices that convert electrical energy into visible light. They can directly convert electricity into light. The heart of an LED is a semiconductor chip, with one end attached to a support, serving as the negative electrode, and the other end connected to the positive electrode of the power supply. The entire chip is encapsulated in epoxy resin. Some existing LED lights are equipped with microwave radar sensors that can automatically detect human presence and control the LED lights to turn on and off.

[0003] The existing LED microwave radar sensor lights have the following drawbacks during use: the microwave radar is generally installed in the middle of the LED and faces downwards. This setting has a small sensing range, which can easily lead to situations where people are within the light's illumination range but not within the radar's range, causing the LED to automatically turn off. Therefore, there is room for improvement. Utility Model Content

Detailed Implementation

[0019] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to specific embodiments and accompanying drawings. It should be noted that, unless otherwise specified, the embodiments and features of the present utility model can be combined with each other.

[0020] Some embodiments of this utility model are described below with reference to the accompanying drawings.

[0021] Example 1:

[0022] Combination Figure 1-4 As shown, this embodiment provides a 15W microwave radar sensing LED light, including: a main body 100.

[0023] The main body 100 includes an LED lamp body 110, multiple annular guide rails 120 fixed on the outer surface of the LED lamp body 110, toothed rings 130 fixed on the outer surface of the annular guide rails 120, an annular frame 140 rotatably sleeved on the annular guide rails 120, a trapezoidal housing 150 fixed on one side of the annular frame 140, a sensor 160 rotatably mounted on the inclined surface of the trapezoidal housing 150, a first drive member 170 mounted on the inner wall of the trapezoidal housing 150 and meshing with the toothed rings 130, and a second drive member 180 mounted on one side of the trapezoidal housing 150, extending into the inner cavity of the trapezoidal housing 150 and abutting against the outer surface of the sensor 160.

[0024] The LED main body is used for lighting, with a power of 15W, making it convenient for use in small areas such as corridors and bedrooms. The circular guide rail 120 is integrally fixed on the outer side of the LED main body 110, with at least two rails, for mounting the circular frame 140 and ensuring the stability of the circular frame 140 when rotating.

[0025] The annular frame 140 has an inverted L-shaped cross-section and is rotatably fitted onto the annular guide rail 120 for mounting the trapezoidal housing 150. The trapezoidal housing 150 is used to mount the sensing element 160 and drive the sensing element 160 to rotate.

[0026] The sensor 160 is used to sense the approach and departure of people in real time, thereby controlling the opening and closing of the LED light body 110. It includes a transparent circular shell 161 rotatably mounted on the inclined surface of the trapezoidal shell 150, a support plate 162 fixed on the inner wall of the transparent circular shell 161, and a microwave radar sensor 163 mounted on the support plate 162. Grooves 151 are formed on the opposite inner surfaces of the inclined surface of the trapezoidal shell 150. Protrusions 1611 are fixed on both sides of the transparent circular shell 161. The protrusions 1611 are rotatably fitted into the grooves 151 to facilitate the rotation of the transparent circular shell 161. The support plate 162 is used to mount the microwave radar sensor 163 and enables the microwave radar sensor 163 to rotate synchronously when the transparent circular shell 161 rotates. The microwave radar sensor 163 can emit microwaves to detect the movement of nearby people, thereby controlling the LED body to open and close.

[0027] The first drive unit 170 is installed on the inner wall of the trapezoidal housing 150. The first motor 171 and the gear 172 are fixed on the shaft of the first motor 171 and fixed on the inner wall of the trapezoidal housing 150. One side of the gear 172 extends out of the trapezoidal housing 150 and meshes with the gear ring 130. With this arrangement, when the first motor 171 starts, it drives the gear 172 to rotate. The gear 172 rotates on the gear ring 130, which drives the trapezoidal housing 150 and the annular frame 140 to rotate, thereby adjusting the orientation of the sensing element 160 for user convenience.

[0028] The second driving component 180 includes a second motor 181 fixed to one side of the trapezoidal housing 150 with its shaft extending into the inner cavity of the trapezoidal housing 150, and a rubber sleeve 182 fixedly sleeved on the shaft of the second motor 181. The rubber sleeve 182 is close to the outer surface of the transparent circular shell 161. With this arrangement, when the second motor 181 is started, the shaft of the second motor 181 rotates, driving the rubber sleeve 182 to rotate. The rotation of the rubber sleeve 182 drives the transparent circular shell 161 to rotate. The rotation of the transparent circular shell 161 drives the microwave radar sensor 163 to rotate through the support plate 162, adjusting the pitch angle of the microwave radar sensor 163. The larger the angle between the microwave radar and its vertical line, the farther the sensing range; conversely, the smaller the angle, the closer the sensing range. That is, the sensing range of the microwave radar sensor 163 is adjusted.

[0029] The working principle and usage process of this utility model are as follows: In use, the first motor 171 is started, driving the gear 172 to rotate. The gear 172 rotates on the gear ring 130, causing the trapezoidal housing 150 and the annular frame 140 to rotate, thus adjusting the orientation of the sensors 160. One sensor 160 is oriented towards the direction in which the person approaches, and the other sensor 160 is oriented towards the direction in which the person moves away. After adjustment, the second motor 181 is started. The rotation of the shaft of the second motor 181 drives the rubber sleeve 182 to rotate, which in turn drives the transparent circular shell 161 to rotate. The rotation of the transparent circular shell 161, through the support plate 162, drives the microwave radar sensor 163 to rotate, adjusting the pitch angle of the microwave radar sensor 163, thus adjusting the sensing range of the microwave radar sensor 163. After adjustment, when a person approaches, the microwave radar sensor 163 on one side detects the person and activates the LED light body 110. When the person detected by the microwave radar sensor 163 on the other side moves away, the LED light body 110 is turned off.
