Description

Technical Field

[0001] This utility model relates to the field of sensor lamp technology, specifically a rotating cover for controlling the sensing range of a sensor on a sensor lamp. Background Technology

[0002] Automatic control products based on infrared technology: When someone enters the sensing range of the switch, a dedicated sensor detects the change in the infrared spectrum of the human body, and the switch automatically turns on the load. As long as the person does not leave and is still moving, the switch remains on; after the person leaves, the switch automatically turns off the load after a delay. The light turns on when someone is there and turns off when the person leaves, which is convenient, safe and energy-saving.

[0003] The above-mentioned technical conditions still have some defects: the current sensor lights generally have a fixed and unadjustable sensing range, which makes them prone to false triggering (such as when a pet passes by) or missed triggering (such as in large-angle blind spots) in complex environments. Although there are methods to adjust the sensitivity through circuitry in the existing technology, it is impossible to accurately control the sensing direction and the operation is complicated.

[0004] Based on this, the present invention designs a rotating cover on an induction lamp to control the sensing range of the sensor, in order to solve the above problems. Utility Model Content

[0007] By adopting the above technical solution, the light-transmitting part can be easily changed.

[0008] Preferably, the lamp holder has through holes on both sides, and the switch knob extends to the outside of the lamp holder through the through holes. Limiting blocks are provided on both sides of the lamp holder and on the two sets of through holes.

[0009] By adopting the above technical solution, damage to the circuit board contacts can be prevented due to excessive rotation.

[0010] Preferably, a toggle block is provided on both sides of the top of the rotating ring.

Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0025] The following is in conjunction with the appendix Figure 1-3 This application will be described in further detail.

[0026] A rotating cover for controlling the sensing range of a sensor on an induction lamp includes a base 1, a lamp holder 2 on the base 1, a control circuit board 3 inside the lamp holder 2, an LED bead 4 and a sensor (not labeled in the attached figure) on the control circuit board 3, the control circuit board 3 being connected to an external circuit to power the LED bead 4, a switch knob 5 on both sides of the control circuit board 3, a rotating base 8 fixedly connected to the top of the lamp holder 2, a lamp cover 9 inside the rotating base 8 for emitting light generated by the LED bead 4, a rotating ring 10 on the rotating base 8, side covers 11 fixedly connected to both sides of the rotating ring 10, a light-transmitting part between the two sets of side covers 11 for transmitting the induction light, and the light emission position can be changed when the rotating ring 10 rotates.

[0027] Furthermore, through holes 6 are provided on both sides of the lamp holder 2, and the switch knob 5 extends to the outside of the lamp holder 2 through the through holes 6. Limiting blocks 7 are provided on both sides of the lamp holder 2 and on the two sets of through holes 6, which can limit the rotation angle of the switch knob 5 and prevent it from rotating excessively.

[0028] Furthermore, a lever block 12 is provided on both sides of the top of the rotating ring 10, which allows the rotating ring 10 to be rotated easily.

[0029] Furthermore, a mounting base 13 is fixedly connected to the bottom edge of the lampshade 9, and multiple positioning holes 14 are provided on the mounting base 13. Multiple positioning posts 15 that are compatible with the positioning holes 14 are fixedly connected to the bottom inner side of the rotating base 8, which can effectively install and snap the lampshade 9.

[0031] The implementation principle of this embodiment is as follows:

[0032] When in use, by turning the toggle block 12 of the rotating ring 10, the side cover 11 is rotated to the target angle (e.g., 60°). At this time, the side cover 11 blocks the side receiving surface of the sensor, retaining only the sensing capability of the corresponding area of ​​the light-transmitting part, which can adjust the sensing range. Press the snap-fit ​​part 16 to remove the rotating ring 10, and then replace the side cover 11 to realize the quick replacement of the side cover 11 and increase its usage effect.
