Detailed Description

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

It should be noted that all the directional indicators (such as up, down, left, right, front, and rear … …) in the embodiment of the present invention are only used to explain the relative position relationship between the components, the movement situation, etc. in a specific posture (as shown in the drawing), and if the specific posture is changed, the directional indicator is changed accordingly.

The embodiment of the utility model discloses a lighting device which can be applied indoors or outdoors to provide light for lighting, and an infrared remote control can emit an infrared light signal to control the lighting device so as to change the illumination brightness and intensity of the lighting device.

Referring to fig. 1 to 3, an embodiment of a lighting device includes a lamp housing 100, a lamp housing 200, a light source module (not shown) and a receiving module 300, the lamp housing 100 and the lamp housing 200 enclose a light source cavity 400, the light source module is disposed in the light source cavity 400 and spaced apart from the lamp housing 200, the lamp housing 200 is a light-transmitting member, so that the light emitted from the light source module can be emitted through the lamp housing 200, the receiving module 300 is disposed in the light source cavity 400 and electrically connected to the light source module, the receiving module 300 is connected to the lamp housing 200, by connecting the receiving module 300 with the lampshade 200, the receiving module 300 can be closer to the infrared light signal outside the lighting device, the infrared light signal outside the lighting device can be more easily received by the receiving module 300, meanwhile, the interference of light rays emitted by the light source module in the lighting device can be reduced, and the receiving capability of infrared light signals of the lighting device is further enhanced.

In this embodiment, the receiving module 300 includes a receiving surface 310 disposed away from the light source module, and the receiving surface 310 is used for receiving the infrared light signal, and since the receiving surface 310 for receiving the infrared light signal is disposed away from the light source module, interference of light emitted by other components and the light source module in the lighting device on receiving the infrared light signal by the receiving module 300 can be reduced, so as to further improve the infrared light signal receiving capability of the lighting device.

It can be understood that, in the conventional lighting device, the receiving module 300 is disposed in the middle of the light source cavity 400, and the infrared light signal of the infrared remote control needs to pass through the lamp cover 200 and pass through a part of the light source cavity 400 and the related devices before being received by the receiving module 300. On one hand, since the infrared light signal has a certain loss when passing through a part of the light source cavity 400 and related devices, the infrared light signal emitted by the infrared remote control at a short distance can be received by the receiving module 300, and when the infrared remote control is far away from the lighting device and the infrared light signal emitted by the infrared remote control reaches the receiving module 300, the intensity of the infrared light signal is not enough to be received by the receiving module 300, which results in the failure of the infrared remote control to control the lighting device; on the other hand, since the receiving module 300 is disposed in the middle of the light source cavity 400, stray light of the light source module and other light emitting devices will form light pollution, which will interfere with the infrared light signal receiving capability of the receiving module 300, and further will cause the control failure of the infrared remote control on the lighting device.

In this embodiment, the receiving module 300 is disposed on the lamp shade 200, on one hand, loss of the infrared light signal when passing through a part of the light source cavity 400 and related devices is avoided, so that the infrared light signal outside the lighting device is more easily received by the receiving module 300, and the receiving capability of the infrared light signal of the lighting device is improved; on the other hand, since the receiving module 300 is disposed on the lampshade 200 and the receiving surface 310 for receiving the infrared light signal is disposed away from the light source module, the influence of the light pollution of the light source module and other light emitting devices on the receiving capability of the receiving module 300 can be minimized.

Therefore, by changing the installation position of the receiving module 300, the receiving module 300 can receive the infrared light signal emitted by the infrared remote control at a distance farther away, so as to better complete the control of the lighting device and improve the remote detection capability of the receiving module 300.

In an embodiment, referring to fig. 4 and 5, the lamp housing 200 is provided with a mounting portion 210, a mounting groove 211 is formed on a side of the mounting portion 210 close to the light source cavity 400, and the receiving module 300 is at least partially received in the mounting groove 211, so that the receiving surface 310 is received in the mounting groove 211.

The mounting portion 210 can fix the receiving module 300 on the lamp housing 200, and the receiving module 300 can be fixed to the mounting groove 211 in a snap-fit manner, so that the receiving module 300 can be mounted on the lamp housing 200.

Because the receiving surface 310 is installed in the installation groove 211, the interference of the light emitted by the light source module to the receiving module 300 can be reduced, and the receiving capability of the infrared light signal of the receiving module 300 is further ensured.

It is understood that the orientation of the receiving surface 310 is the receiving direction of the infrared light signal, and the orientation of the receiving surface 310 can be adjusted appropriately to change the receiving capability of the receiving module 300 for receiving the infrared light signal in a specific direction. The receiving surface 310 may be arranged at an angle alpha with respect to the axial direction of the illumination device, e.g. 10 deg. ≦ alpha ≦ 30 deg..

It is understood that the position and orientation of the receiving surface 310 relative to the lamp housing 100 can be selected according to the requirements of installation and infrared signal control.

Preferably, the receiving surface 310 is a curved surface, which facilitates the reception of infrared light signals in various directions.

The guide surface 212 may be curved or inclined. The guide surface 212 may change the direction of propagation of the infrared light signal by refraction.

The arrow trace in fig. 8 is the propagation path of the infrared light signal. The infrared signal emitted by the infrared remote control can be guided to the receiving surface 310 by the guiding surface 212, so that the sensitivity of receiving the infrared signal of the receiving module 300 can be improved, the receiving module 300 can receive the infrared signal more conveniently, and the infrared signal receiving capability of the lighting device is further improved.

Since the control signal sent by the infrared remote control is an infrared signal, the infrared signal received by the receiving module 300 in this embodiment is an infrared signal.

Of course, the mounting portion 210 may also be a raised crater structure.

The infrared signal emitted by the infrared remote control can pass through the outer wall of the lampshade 200 and is converged to the receiving surface 310 through the refraction of the guide surface 212, which is more beneficial for the receiving module 300 to receive the infrared signal.

Therefore, by the structural arrangement of the mounting portion 210, the detection range and the detection angle of the infrared light signal of the receiving module 300 can be increased, so that the receiving module 300 can detect the infrared light signal in a wider range, and the detection and receiving angle of view of the infrared light signal by the receiving module 300 can reach more than 180 degrees.

Further, a light-gathering cup may be disposed between the light source module and the lamp cover 200, and the light-gathering cup may gather the light emitted from the light source module to the lens 700, so as to further improve the illumination brightness and intensity of the lighting device.
