Detailed Description

In order to facilitate understanding of the present invention, the present invention will be described more fully hereinafter with reference to the accompanying drawings. Preferred embodiments of the present invention are shown in the drawings. The invention may, however, be embodied in many different forms and should not be construed as limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete.

It will be understood that when an element is referred to as being "secured to" another element, it can be directly on the other element or intervening elements may also be present. When an element is referred to as being "connected" to another element, it can be directly connected to the other element or intervening elements may also be present. The terms "vertical," "horizontal," "front," "back," "top," "bottom," "left," "right," "up," "down," and the like as used herein are for illustrative purposes only.

Unless defined otherwise, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention belongs. The terminology used in the description of the invention herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. As used herein, the term "and/or" includes any and all combinations of one or more of the associated listed items.

The invention will be further described with reference to the accompanying drawings and specific embodiments:

as shown in fig. 1 and 2, a projection lamp includes a housing 10, a front panel 11 and a rear panel 12 are respectively disposed at the front and the rear of the housing 10;

a projection part 20, a human body sensor 30 and a light supplement lamp 40 are respectively arranged in the shell 10 at positions close to the front panel 11, and light holes through which light can pass are respectively arranged at positions of the front panel 11 corresponding to the projection part 20, the human body sensor 30 and the light supplement lamp 40;

the shell 10 is internally provided with a control panel, and the control panel is electrically connected with the projection part 20, the human body sensor 30 and the light supplement lamp 40 respectively.

When the human body sensor 30 is in use, the light supplement lamp 40 performs light supplement illumination according to the intensity of ambient light, so that the human body sensor can clearly and reliably monitor the state of a human body in the projection area; when the motion of the human body is monitored by the human body sensor 30, the human body sensor 30 sends a signal to the controller, and then the controller projects a set figure, text or video to a designated area through the projection part 20. For example, according to the position of the human body, a projection route guide mark and the like, the interaction between the human body movement and the projection picture is realized.

Further, the rear panel 12 is provided with an air inlet and an air outlet through which air can penetrate, and an air inlet baffle 13 and an air outlet baffle 14 are respectively arranged on the outer sides of the air inlet and the air outlet.

The heat dissipation fan of the projection component 20 is aligned with the air outlet, so that the high-temperature gas inside the projection component 20 and the projection lamp is blown out from the air outlet, and the outside air enters from the air inlet, so that the inside of the projection lamp is kept at a proper temperature. The air inlet baffle 13 and the air outlet baffle 14 cover the air inlet and the air outlet respectively, so that air flows pass through the side gaps between the air inlet baffle 13 and the rear panel 12 and between the air outlet baffle 14 and the rear panel respectively, and foreign matters are prevented from directly entering the projection lamp.

Further, a bracket 50 is arranged on the housing 10, the bracket 50 is in an "n" shape, and two sides of the "n" shape are respectively connected with two sides of the housing 10 through a handle 51 in an elastic manner. By tightening or loosening the handle 51, the projection angle or position of the projection lamp can be adjusted quickly and conveniently.

When the projection lamp is used, the bracket 50 can be connected with the holder, so that the projection lamp can adjust the projection angle or position of the projection lamp in real time according to the human body position detected by the human body sensor 30.

Further, a network interface 60 and an audio interface 70 electrically connected to the controller are disposed on the rear panel 12.

In this embodiment, the network interface 60 uses an RJ45 interface, which is used for remote network connection of projection lamps and data transmission, and also can be used for interconnection of a plurality of projection lamps to realize interactive control among the plurality of projection lamps; the audio interface 70 uses a 3.5mm coaxial audio interface for audio transmission, so that the projection lamp can perform sound interaction besides light and shadow interaction.

Further, a light-transmitting protection plate is arranged between the light-transmitting hole and the projection part 20, the human body sensor 30 and the light supplement lamp 40, and the protection plate is used for preventing the projection part 20, the human body sensor 30 and the light supplement lamp 40 from being contacted by external objects and preventing dust from entering the projection lamp.

Various other modifications and changes may be made by those skilled in the art based on the above-described technical solutions and concepts, and all such modifications and changes are intended to fall within the scope of the present invention.
