[0002] With the rapid development of the lighting industry at home and abroad, both professionals and ordinary users have higher and higher demands on lighting, which are becoming more and more professional. However, the lamps on the market currently only meet their needs for different lighting scenes by adjusting the luminous flux (unit: Lm).

[0003] As a common lighting equipment, floodlights are popular for their special design and wide range of applications. Floodlights are usually equipped with high-brightness light sources, which can provide strong and uniform lighting and are suitable for large areas such as outdoor landscape lighting, stadiums, building lighting, etc. Modern floodlights use LED technology, which has the characteristics of long life and high durability, greatly reducing maintenance and replacement costs.

[0004] However, despite their wide application in many fields, floodlights also have a significant drawback, which is the inability to adjust the lighting range. When the area to be illuminated is small, traditional floodlights may produce too much light, wasting energy and resources. When a larger area needs to be covered, traditional floodlights may not provide enough lighting, affecting visibility and safety. Traditional floodlights usually have a fixed lighting range, which means that the lighting range cannot be adjusted according to specific needs.

[0005] Although some current lamps can adjust the brightness, when the distance between the lamp and the area to be illuminated changes, the output brightness remains fixed, so that the brightness of the lamp output is inconsistent with the current distance of the lamp, resulting in inappropriate brightness of the area to be illuminated. Summary of the invention

DETAILED DESCRIPTION

[0019] In order to further explain the technical means and effects adopted by the present invention to achieve the predetermined invention purpose, the specific implementation methods, structures, features and effects of the present invention are described in detail below in conjunction with the accompanying drawings and preferred embodiments.

[0020] See also Figure 1-Figure 2 The present embodiment provides a lamp with an adjustable lighting range, including a base 1, a light-emitting unit 2, an adjustment mechanism 3, an adjustable lampshade 4, an adjustment module 5 and an angle monitoring module 6. The adjustment mechanism 3 is installed on the top surface of the base 1, and the light-emitting unit 2 is installed at the adjustment end of the adjustment mechanism 3. The irradiation angle of the light-emitting unit 2 is adjusted by the adjustment mechanism 3, and the adjustable lampshade 4 is provided on the outer side cover of the light-emitting unit 2. At the same time, an angle monitoring module 6 is installed at the adjustment end of the adjustment mechanism 3, and the angle change of the adjustment end is detected by the angle monitoring module 6. The adjustment module 5 is installed at the adjustment end for adjusting the luminous intensity of the light-emitting unit 2.

[0021] When placing lamps in conference rooms or shopping malls, the illumination position and illumination intensity of the lamps need to be adjusted to ensure the brightness of the scene. The illumination range and illumination intensity of existing lamps are usually in a linear relationship. The closer the installation distance of the lamp, the smaller the illumination range and the higher the luminous intensity. Conversely, the farther the installation distance of the lamp, the larger the illumination range and the lower the luminous intensity. Before the design, the luminous intensity and illumination range of the lamp are fixed. Once the illumination range of the lamp needs to be adjusted, the luminous intensity within the illumination range will change. Regardless of whether the luminous intensity becomes stronger or weaker, it will affect the visual experience of the lighting. Therefore, when changing the luminous range, the luminous intensity needs to be adjusted.

[0022] When adjusting the lighting range of the lamp, the illumination angle of the light-emitting unit 2 is changed by adjusting the adjustment mechanism 3. At this time, the light-emitting unit 2 changes from the original vertical illumination to the inclined illumination. The illumination distance is changed, resulting in a change in the illumination range, which will affect the brightness of the illumination area, thereby affecting the brightness change of the illumination and people's viewing experience. Therefore, in order to avoid the situation where the brightness of the illumination area is not appropriate due to the change of the light intensity within the illumination range when the lamp is adjusted, and the occurrence of inappropriate brightness of the illumination area, when the light-emitting unit 2 changes the illumination angle, the angle monitoring module 6 at this time changes the angle of the adjustment of the adjustment mechanism 3. Detection is performed and the detection result is transmitted to the adjustment module 5. The adjustment module 5 adjusts the luminous intensity of the light-emitting unit 2 according to the ratio between the illumination range and the illumination intensity of the lamp to ensure that the light-emitting unit 2 will have the same illumination intensity after the illumination range is changed, and the illumination brightness will not be insufficient or excessive due to the change in the illumination range. At the same time, if it is necessary to adjust the illumination range without changing the installation distance and the illumination angle, the illumination range of the light-emitting unit 2 can be adjusted by the adjustable lampshade 4. At this time, the adjustment module 5 will also adjust the luminous intensity of the light-emitting unit 2 according to the adjustment angle of the adjustable lampshade 4.

[0023] In order to better adjust the angle of the light-emitting unit 2 to change the irradiation range, in the present embodiment, the adjustment mechanism 3 includes an adjustment plate 31 and three groups of adjustment components. The bottom ends of the three groups of adjustment components are rotatably connected to the top surface of the base 1, and the adjustment ends are rotatably connected to the bottom surface of the adjustment plate 31. The adjustment ends of the three groups of adjustment components are triangular and evenly connected to the bottom surface of the adjustment plate 31. When the angle of the light-emitting unit 2 is adjusted, the angle of the adjustment plate 31 is changed by adjusting the distance between the three groups of adjustment components, thereby completing the adjustment of the irradiation range of the light-emitting unit 2. Moreover, the uniform arrangement of the three groups of adjustment components can ensure the stability of the adjustment plate 31 during the adjustment process, and avoid irregular deflection of the adjustment plate 31 during the adjustment process, thereby affecting the accuracy of the adjustment range of the lamp.

[0024] In order to further ensure that the adjustment accuracy of the adjustment plate 31 can remain stable, in one embodiment, each group of adjustment components is composed of two adjustment rods 32, the adjustment ends of the two adjustment rods 32 are close to each other and rotatably connected to the bottom surface of the adjustment plate 31, and the bottom ends of the two adjustment rods 32 are away from each other and close to the bottom ends of the adjustment rods 32 in the adjacent adjustment components and rotatably connected to the top surface of the base 1. That is to say, each group of adjustment components is composed of two adjustment rods 32, the top ends of each group of adjustment rods 32 are close to each other to support and adjust the angle of the adjustment plate 31, and the bottom ends of the adjustment rods 32 in each group of adjustment components will be close to the lower ends of the adjustment rods 32 of the adjacent adjustment components as support, so that the adjustment rods 32 can adjust the inclination angle of the adjustment plate 31 when adjusting their own support height, thereby completing the adjustment of the irradiation range of the light-emitting unit 2, and the tail ends are installed tilted to both sides to ensure the stability of the entire adjustment plate 31 during the adjustment process, avoiding irregular deflection of the adjustment plate 31 when adjusting the inclination angle.

[0025] In order to better adjust the adjustable lampshade 4 to change the irradiation range of the light-emitting unit 2, in one embodiment, the adjustable lampshade 4 includes a plurality of protective plates 41 and a surrounding plate 42, the surrounding plate 42 is installed on the top surface of the adjustment plate 31 and covers the light-emitting unit 2, the plurality of protective plates 41 are trumpet-shaped and the bottom ends are rotatably connected to the top surface of the surrounding plate 42, the outer bottom of the surrounding plate 42 is provided with a plurality of slide grooves 421, and a plurality of slide grooves 421 are provided with sliders 422, the top surface of the slider 422 is rotatably connected to a connecting rod, and the top end of the connecting rod is rotatably connected to the side wall of the protective plate 41, and the adjustable lampshade 4 is adjusted to change the irradiation range. When the range of illumination is within a certain range, the slider 422 slides in the slide groove 421 to pull the protective plate 41 to rotate to change the range of illumination. In order to ensure that the slider 422 can maintain accuracy during the sliding process, an electromagnetic component is provided in the slide groove 421 to attract the sliding distance of the slider 422 through electromagnetic force. At the same time, an encoder can be installed on one side of the slide groove 421 to monitor the moving distance and speed of the slider 422, so as to achieve precise adjustment. The encoder is then connected to the adjustment module 5 so that the adjustment module 5 can adjust the luminous intensity of the light-emitting unit 2 according to the adjustment range of the adjustable lampshade 4.

[0026] In order to avoid that when the protective plate 41 changes its illumination range, there is a light and shadow deviation between the light emitted from the gap of the protective plate 41 by the light-emitting unit 2 and the area blocked by the protective plate 41, thereby affecting the overall lighting effect, in one embodiment, the protective plate 41 is provided with a connecting groove on both side walls close to the adjacent protective plates 41, and a connecting film 411 is provided in the connecting groove, and the connecting film 411 is connected to the connecting groove between the two adjacent protective plates 41. The connecting film 411 provided between the two adjacent protective plates 41 can ensure that the gap formed between the protective plates 41 when the protective plates 41 are opened will not cause a light and shadow deviation with the area blocked by the protective plates 41.

[0027] In order to ensure that the connecting film 411 can maintain the stability of the connection and maintain the same shielding effect as the protective plate 41 when the protective plate 41 changes the illumination range, in one embodiment, the connecting film 411 is composed of a flexible film and a protective film, and both sides of the protective film are connected to the connecting groove through a flexible film. The flexible film ensures that the connecting film 411 can effectively block the gap when the protective plate 41 is unfolded, thereby avoiding the occurrence of light and shadow differences.

[0028] Since the lamp may discolor and become brittle due to ultraviolet radiation during use, thus affecting its service life, in order to increase the service life of the adjustable lampshade 4 and improve its durability and safety, in one embodiment, the inner wall of the lampshade is coated with an anti-ultraviolet coating. By coating the anti-ultraviolet coating on the inner wall of the lampshade, the color and transparency of the lampshade can be maintained, and discoloration and brittleness caused by ultraviolet radiation can be avoided, thereby improving the durability and safety of the adjustable lampshade 4.

[0029] In order to detect the inclination angle of the adjustment plate 31 more accurately, in one embodiment, the angle monitoring module 6 is composed of a gyroscope. The gyroscope is not only small in size, but can also be better installed on the adjustment plate 31. At the same time, the gyroscope can monitor the angle change in real time, so that the adjustment module 5 can better control the luminous intensity of the light-emitting unit 2.

[0030] In order to better control and adjust the luminous intensity of the light-emitting unit 2, in one embodiment, the adjustment module 5 adjusts the luminous intensity of the light-emitting unit 2 through linear dimming. By changing the duty cycle of the PWM signal, the average current of the light-emitting unit 2 can be linearly adjusted, thereby realizing linear adjustment of the brightness. The adjustment mechanism 3 and the adjustable lampshade 4 can accurately complete the adjustment of the luminous intensity when adjusting the illumination range.

Although the present invention has been disclosed as a preferred embodiment as above, it is not used to limit the present invention. Any technical personnel in this field can make some changes or modify the technical contents disclosed above into equivalent embodiments without departing from the scope of the technical solution of the present invention. However, any simple modification, equivalent change and modification made to the above embodiments according to the technical essence of the present invention without departing from the content of the technical solution of the present invention still fall within the scope of the technical solution of the present invention.
