Description

Technical Field

[0001] The utility model relates to the technical field of lamp lighting control, in particular to an infrared sensing device applied to bedside table lamp lighting. Background Art

[0002] Hotel rooms often feature spotlights and other lighting fixtures for localized illumination in various areas, such as above the bedside table, in front of the bathroom mirror, above the pillow in the sleeping area, and above the guest desk. The switches for these spotlights are grouped together and mounted on the wall, forming a switch bank. When a guest wakes up at night and wants to get something from the bedside table, they first need to turn on the switch for the spotlight illuminating the bedside table. However, the switch bank combines the switches for all the spotlights in the room. In the dark, it's difficult for the guest to determine which switch controls the spotlight illuminating the bedside table, so they must turn on each switch individually until they find the one that illuminates the bedside table.

[0003] To prevent passengers from having difficulty turning on the nightstand spotlight in the dark, existing technology replaces the spotlight switch with an infrared sensor mounted above the nightstand. This sensor senses a person's presence and activates the nightstand spotlight. However, infrared sensors typically have a radial sensing range, and when installed above the nightstand, the sensing range is fixed. A narrow sensing range makes it difficult for passengers to activate the nightstand spotlight. A wide range might cover the bedside, making it easy for passengers to accidentally activate the nightstand spotlight while in bed. Utility Model Content

[0004] The purpose of the invention of the utility model is to provide an infrared sensing device for lighting a bedside table lamp, so as to prevent passengers from accidentally triggering the bedside table spotlight to light up while lying in bed.

[0005] To achieve the above-mentioned purpose, the utility model provides an infrared sensing device for bedside table lamp lighting, comprising a bracket and a mounting bracket fixed above the bedside table, the bracket being movably connected to the mounting bracket in the form of a top hinged mounting bracket, the bracket being able to be lifted around the hinge until it stays in a horizontal state, an infrared sensor being provided at the free end of the bracket, and when the bracket is in the horizontal state, the sensing direction of the infrared sensor is downward; a sensing cover is provided on the outside of the infrared sensor, the sensing cover comprising a plurality of baffles, which are enclosed together to block the sides of the infrared sensor, a mounting portion is provided inside the sensing cover, an array of protrusions is provided on the outer surface of the mounting portion, and an array of positioning grooves is correspondingly provided on the inner surface of the baffle, the baffle being detachably connected to the mounting portion in a snap-fit manner so that the baffle can be hung on the top of the mounting portion or on the bottom of the mounting portion.

[0006] Preferably, a groove for the bracket to be embedded is opened on the front of the mounting frame. The bracket rotates from a horizontal state around the hinge toward the mounting frame until it is embedded in the groove and stored in the mounting frame. In this state, the infrared sensor is blocked by the groove wall.

[0007] Preferably, the infrared sensor is a wireless infrared sensor.

[0008] Preferably, the infrared sensor is provided with a mounting portion for connecting to the bracket on the outside, the infrared sensor has threads on the outer surface, and corresponding matching threads are provided on the inner surface of the mounting portion. The infrared sensor is specifically connected to the bracket via the threaded mounting portion.

[0009] Preferably, the outer surface of the mounting portion is provided with a protrusion array on the left and right side surfaces respectively, and the inner surfaces of the left baffle and the right baffle are provided with a positioning groove array accordingly.

[0010] Preferably, the baffle is a trapezoidal plate.

[0011] Preferably, the mounting portion is a step platform, and the baffle has the same shape as the side surface of the mounting portion.

[0012] The beneficial effects of the utility model are:

[0013] After the guest checks into the guest room, he / she lifts the bracket until it stops in the horizontal position. At this time, the positioning groove on the top of the baffle is stuck in the protrusion on the top of the mounting part.

DETAILED DESCRIPTION

[0020] The present invention is further described in detail below in conjunction with specific embodiments.

[0021] Infrared sensing devices used for bedside table lighting, such as Figure 1 As shown, it includes a bracket 1 and a mounting bracket 2 fixed above the bedside table. The front of the mounting bracket 2 is provided with a groove 8 for the bracket 1 to be embedded. The bracket 1 can be embedded in the groove 8 and thus stored in the mounting bracket 2. The bracket 1 is movably connected to the mounting bracket 2 in the form of a top hinge. The bracket 1 can be lifted around the hinge until it stops. Figure 1 The free end of the bracket 1 is provided with an infrared sensor 3. When the bracket 1 is in the horizontal state, the sensing direction of the infrared sensor 3 is downward. The infrared sensor 3 adopts a wireless infrared sensor 3, such as Figure 2 As shown, the exterior of the mounting portion 5 is provided with a mounting portion 5 for connecting to the bracket 1. The outer surface of the infrared sensor 3 is provided with threads 6, and the inner surface of the mounting portion 5 is provided with corresponding mating threads 6. The infrared sensor 3 is connected to the bracket 1 by connecting the mounting portion 5 via the threads 6. The mounting portion 5 is a step-shaped platform, and the exterior of the mounting portion 5 is provided with a sensor cover 4. The sensor cover 4 includes four trapezoidal baffles that conform to the shape of the side surfaces of the mounting portion. These baffles are respectively front baffle A, left baffle B, rear baffle C, and right baffle D. These baffles enclose together to block the sides of the infrared sensor 3. The outer surface of the mounting portion 5 is provided with arrays of protrusions 7 on the left and right sides, respectively. The protrusion arrays 7 are distributed in the top and bottom areas of the side surfaces of the mounting portion. The inner surfaces of the baffles are provided with corresponding arrays of positioning grooves. The left baffle B and the right baffle D are detachably connected to the mounting portion by snapping.

[0022] After the guest checks into the guest room, he lifts the bracket 1 until it stops in the horizontal position. At this time, the positioning groove on the top of the baffle is stuck in the protrusion on the top of the mounting part. The sensing range of the infrared sensing device on the bracket can cover the bedside, and the guest can also trigger the bedside table lamp to light up while in bed; if there is only one bed in the room and the bedside table is located on the left side of the bed, the guest has the habit of getting up at night, and can remove the baffle D near the right and install it on the bottom of the mounting part before going to sleep. The side baffle limits the sensing range of the infrared sensor 3 to the bedside table area, that is, the boundary of the sensing range retreats from the original Q on the bed to P on the bedside table. Therefore, the infrared sensor 3 will not sense the human body information sleeping on the bed, avoiding the guest from accidentally triggering the spotlight of the bedside table while in bed. When the guest gets up at night, he only needs to reach under the infrared sensor 3 on the bedside table, and the infrared sensor 3 can be sensed and trigger the spotlight of the bedside table to light up and provide lighting. When the room is bright enough or the bedside table spotlight is not needed, the passenger can push the bracket 1 down to a state where it is embedded in the groove 8 to avoid triggering the infrared sensor 3 and turning on the bedside table spotlight.

[0023] In the above embodiment, there is only one bed and the bedside table is located on the left side of the bed. The passenger only needs to install the right baffle D on the bottom side of the mounting portion 5 to prevent the infrared sensor 3 from sensing human activity information on the bed. If there are two beds in the room and the bedside table is located between the two beds, the passenger can install the left baffle B and the right baffle D on the bottom side of the mounting portion 5 respectively to prevent the infrared sensor 3 from sensing human activity information on the beds on both sides.

[0024] The above is only an embodiment of the present invention and does not limit the scope of patent protection. Those skilled in the art can make non-substantial changes or substitutions based on the present invention and still fall within the scope of patent protection.
