DETAILED DESCRIPTION

[0023] In order to make the purpose, technical solution and advantages of the utility model more clear, the utility model is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the utility model and are not used to limit the utility model.

[0024] A wall lamp, referring to Figure 1-4, including a wall lamp shell 5 and a wall lamp back cover 1, both of which have a hollow cavity. An LED light source board 8 and a forward-leaning mounting frame 4 are arranged in the wall lamp shell 5. Both ends of the LED light source board 8 protrude outward to form a rotating shaft portion 804 that is rotatably installed in the wall lamp shell 5. The above design enables the LED light source board 8 to rotate in the wall lamp, thereby realizing the adjustment of the angle of the LED light source board 8. When the LED light source board 8 is in a horizontal state (the lamp beads are facing downward), the light is emitted vertically downward, and it can be used as a full-cutoff lamp. When the LED light source board is at 15° or other angles (the lamp beads are facing downward), the light is emitted vertically downward, and it can be used as a half-cutoff lamp. It can be adjusted according to the needs of the user. At the same time, the light output range can also be adjusted when the angle is adjusted, and it has better applicability.

[0025] Reference Figure 2 and Figure 3 As shown, arc blocks 801 are provided at both ends of the back side of the LED light source board 8, and a plurality of threaded holes 802 are provided at equal intervals on the arc blocks 801. The mounting frame 4 is locked together with one of the threaded holes 802 of the arc blocks 801 by fixing screws, so as to realize the locking operation after the LED light source board 8 is adjusted to different light output angles. Before each angle adjustment of the LED light source board 8, the fixing screws are first loosened. At this time, due to the lack of fastening force, the angle of the LED light source board 8 can be manually adjusted. When the angle is adjusted, the position of the arc block 801 will also change accordingly. Then, according to the position of the threaded hole 802 after adjustment, it is locked together with the mounting frame 4 again to complete the limiting operation after the LED light source board 8 is adjusted.

[0026] Furthermore, the back cover 1 of the wall lamp is provided with a PCB board 10 and a driving power supply 3, and a photosensitive probe 11 is integrated on the PCB board 10. The PCB board 10 is electrically connected to the driving power supply 3 and the LED light source board 8. The side wall of the back cover 1 of the wall lamp is provided with a through hole for the photosensitive probe 11 to extend out, and an additional light control part is designed on the wall lamp. The photosensitive probe 11 is used to sense the intensity of external light, and the brightness and color temperature of the LED lamp beads in the LED light source board 8 (with lamp beads) are adjusted accordingly according to the brightness and color temperature of the external light. The brightness and color temperature can be adjusted to the user's desired brightness and color temperature in a variety of environments to meet the diverse requirements of consumers; when the external light is weak, the LED lamp beads emit high brightness, and when the external light is strong, the brightness of the LED lamp beads is weakened, which can further save energy.

[0027] In addition, an operating surface 102 is provided on the back cover 1 of the wall lamp above the photosensitive probe 11, and a photosensitive probe switch, a color temperature adjustment knob and a power adjustment knob are provided in the operating surface 102. When the light control part is not needed, the light control part can also be manually turned off, and the color temperature and brightness can also be manually adjusted by the color temperature adjustment knob and the power adjustment knob.

[0028] It should be noted that the color temperature and brightness adjustment mentioned above are both currently available technologies, so the specific structures and circuits will not be described one by one.

[0029] Furthermore, the front end inclined surface of the wall lamp shell 5 has an opening, and a light-transmitting cover 7 is installed at the opening of the wall lamp shell 5. The light-emitting side of the LED light source panel 8 faces the light-transmitting cover 7. The light-transmitting cover 7 and the wall lamp shell 5 are both triangular prism structures. The light-transmitting cover 7 can not only satisfy the requirement of light transmission, but also provide additional protection for the internal structure to prevent foreign matter or dust from entering the wall lamp and affecting the operation of the wall lamp.

[0030] Furthermore, the angle difference between each threaded hole 802 is 15°. After the threaded hole 802 at the bottom of the arc block 801 is combined with the mounting frame 4, the LED light source panel 8 is in a horizontal state as a whole, which is used to achieve a full light cutoff effect. The angle between each threaded hole 802 is certain and can be adjusted to the required angle as needed. If you want the light to be emitted farther, you can adjust the angle to a larger range.

[0031] Furthermore, a plurality of pins 101 are vertically provided on the side wall at one end of the wall lamp back cover 1, and a plurality of connecting rings 501 for cooperating with the pins 101 are installed on the side wall at one end of the wall lamp shell 5. The pins 101 pass through the through holes of the connecting rings 501 to form a connecting shaft structure. Through the above structural design, when it is necessary to adjust the light-emitting angle of the wall lamp or maintain the internal components, the wall lamp shell 5 can be opened outward at a certain angle, and the corresponding operation can be performed at this time. The wall lamp shell 5 and the wall lamp back cover 1 can be combined into a whole, which is more convenient during installation or disassembly.

[0032] Furthermore, the other side wall of the wall lamp rear cover 1 is provided with a rear mounting ear 102 with a screw hole, and the other side wall of the wall lamp shell 5 is provided with a front mounting ear corresponding to the rear mounting ear 102, and the rear mounting ear 102 and the front mounting ear are locked by screws 6.

[0033] In addition, in order to ensure an additional sealing effect, additional fixing structures similar to mounting ears can be designed on the other sides of the wall lamp back cover 1 and the wall lamp housing 5 (see Figure 1 shown).

[0034] Furthermore, both ends of the mounting frame 4 are bent forward to form a fixing portion, and the fixing portion of the mounting frame 4 is mounted on the front inner wall of the wall lamp shell 5 by means of screws. A light hole 401 is provided at the upper end of the mounting frame 4 corresponding to the threaded hole 802. After the threaded hole 802 is moved to the same horizontal line as the light hole 401, the mounting frame 4 and the LED light source panel 8 can be locked together by using fixing screws.

[0035] Reference Figure 1As shown, stripes are provided on the inner surface and / or outer surface of each cover wall of the light-transmitting cover 7 to further increase the uniformity of light transmission.

[0036] Furthermore, a sealing ring groove is formed at the outer edge of the wall lamp back cover 1, in which a sealing ring 2 is embedded. The sealing ring 2 is interference fit with one end of the wall lamp shell 5 toward the wall lamp back cover 1, so as to form a sealing structure between the wall lamp back cover 1 and the wall lamp shell 5. After the wall lamp back cover 1 and the wall lamp shell 5 are combined, the sealing of the connection between the wall lamp back cover 1 and the wall lamp shell 5 can be guaranteed, thereby achieving dustproof and waterproof effects.

[0037] Furthermore, positioning plates 9 are installed on both sides of the inner wall of the wall lamp shell 5, and a side plate 902 is integrally provided at one end of the positioning plate 9. A rotating rod 901 is rotatably installed at the center of the side plate 902. The end of the rotating rod 901 has an external thread, and the end of the rotating shaft part 804 facing the rotating rod 901 has an internal threaded hole. The rotating shaft part 804 and the rotating rod 901 are threadedly installed together, so that the rotating shaft part 804 can rotate together with the rotating rod 901, thereby completing the adjustment of the angle of the LED light source panel 8.

[0038] Furthermore, the end faces of the two arc-shaped blocks 801 that are separated from each other are both protruding to form a handle 803. The handle 803 can avoid direct contact with the LED light source board 8 when the user adjusts the angle, while ensuring safety and facilitating the adjustment of the angle of the LED light source board 8; wherein the handle 803 is preferably made of plastic.

[0039] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
