Description

Technical Field

[0001] The present invention relates to the field of atmosphere landscape lighting lamps, and in particular to a ripple projection lamp. Background Art

[0002] Currently, with the continuous improvement of people's material and cultural lives, nightscape lighting has become an important part of their pursuit of a better life. The role of nightscape economics in boosting domestic demand is becoming increasingly evident. People's expectations for light are no longer limited to illumination alone, but are increasingly focused on its decorative and entertaining qualities, demanding more natural elements and more psychological implications. Water is a popular element and a key component of Chinese philosophy. The dynamic ripples created when water drops fall into a calm lake are a common undulating phenomenon, accompanied by the corresponding reflection and refraction of light, creating a uniquely ethereal aesthetic. The commonly used technology for achieving dynamic ripples is digital projectors, which rely on linear imaging lamps, typically using single-axis plano-convex mirrors, with a regular imaging optical path. However, these devices are often large and expensive. Consequently, some manufacturers' physical projector lamps suffer from defects such as insufficient brightness and non-concentric apertures, which severely impact the user experience and limit their application scenarios.

[0037] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0038] It should be noted that the descriptions of "first", "second", etc. in the present invention are for descriptive purposes only and should not be understood as indicating or implying their relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features defined as "first" or "second" may explicitly or implicitly include at least one of such features. In addition, the technical solutions between the various embodiments can be combined with each other, but this must be based on the fact that they can be implemented by ordinary technicians in this field. When the combination of technical solutions is contradictory or cannot be implemented, it should be deemed that such a combination of technical solutions does not exist and is not within the scope of protection required by the present invention.

[0039] See also Figure 1 The embodiment of the ripple projection lamp control method of the present invention shown includes the following steps:

[0040] S100: A water ripple light spot is illuminated by a projection lamp. The water ripple light spot can be static or ripple-like and flicker in a certain order.

[0041] S200: Acquire first target information of an object intruding into the light spot range, where the first target information includes the area of the object intruding into the light spot range and the speed at which the object intrudes.

[0042] S300: Adjusting the irradiated water ripple light spot in response to the first target information.

[0043] By identifying the intrusion state of the intruding object on the water ripple light spot, the projection lamp can be controlled to emit different light effects, so that the light can be emitted in a state similar to that of different ripples generated by real objects thrown into the water, which is closer to the effect of natural water ripples, thereby improving the practical application value of the ripple projection lamp. At the same time, the cost is low, which is conducive to large-scale promotion.

[0044] Further, see Figure 2 As shown, in step S200, obtaining first target information of an intruding object within the light spot range specifically includes:

[0045] S210: Identifying a water ripple spot area through a detection component and delineating a boundary of the water ripple spot area;

[0046] S220: When an intruding object appears in the water ripple light spot area, the appearance time T0 of the intruding object is recorded, and the boundary and area S0 of the intruding object in the water ripple light spot area are identified;

[0047] S230: After a predetermined time interval T1, the area S1 and boundary of the intruding object at the time interval T2 are identified, and the speed V1 of the intruding object is calculated, and the larger value of S0 and S1 is selected as S2.

[0048] In this embodiment, the detection component can be an AI camera that identifies intruding objects through visual recognition. Moreover, by setting up an AI camera, the type of intruding object can be set. For example, if the intruding object is set to a human body or a part of a human body, the ripple projector will only interact when the intruding object is a human, and avoid other objects. In some other embodiments, the detection component can also be a laser radar that detects parameters such as the boundary, area, and speed of the intruding object by emitting electromagnetic waves and receiving the reflected waveform.

[0049] Further, see Figure 3 As shown, the step S300: adjusting the irradiated water ripple light spot in response to the first target information specifically includes:

[0050] S310: The water ripple light spot includes at least a first projection effect and a second projection effect, corresponding to different first and second threshold intervals. The first projection effect may be a relatively slowly fluctuating water ripple light spot, while the second projection effect is a relatively violently fluctuating water ripple light spot. Specifically, the water ripple light spot is adjusted by changing the PWM output waveform of the ripple projection lamp.

[0051] S320: S2 and V1 are combined to perform calculations, and corresponding first projection effects and second projection effects are executed according to whether the calculation results fall within the first threshold range and / or the second threshold range.

[0052] Furthermore, after step S230, the following steps are further included:

[0053] Step S240: At T3 after the predetermined time T1, the area S3 of the intruding object and the boundary at T3 are identified, and the acceleration A1 of the intruding object is calculated and whether the acceleration A1 is a positive value or a negative value is determined.

[0054] If acceleration A1 is positive, the above steps are continued, combining S2 and V1 for calculation. If it is negative, the steps are reversed based on whether the calculation result falls within the first and second threshold intervals, executing the corresponding first and second projection effects. That is, when acceleration A1 is negative, if the original calculation result falls within the first threshold interval and thus requires the first projection effect, the second projection effect is executed instead. If the original calculation result falls within the second threshold interval and thus requires the second projection effect, the first projection effect is executed instead. If the number of threshold intervals is N, if the original calculation result falls within the first threshold interval and thus requires the first projection effect, the Nth projection effect is executed instead, and so on.

[0055] Furthermore, before irradiating the water ripple spot with a projection lamp, the step also includes the steps of: identifying the brightness of the surrounding environment and determining whether it is night, and if so, turning on the projection lamp.

[0056] For example, when the projection lamp is turned on, it emits a static or preset dynamic water ripple light spot at night. At this time, if a human body intrudes into the range of the light spot, the detection component detects the intruding object and calculates the area and speed of the intruding object based on the boundary and time. At this time, the area and speed of the intruding object are introduced into the formula J=S2*V1, and the calculation result is compared with the preset threshold range to determine whether it falls into a specific threshold interval, so that the projection lamp performs the corresponding projection effect. For example, if the value of J is small, it means that the intrusion area and speed are not large. When it falls into the first threshold interval, the projection lamp performs the first projection effect, and the frequency and brightness of the water ripple light spot fluctuate slightly; when the value of J is large, it means that the intrusion area and speed are large. When it falls into the second threshold interval, the projection lamp performs the second projection effect, and the frequency and brightness of the water ripple light spot fluctuate greatly, and the display effect is more intense.

[0066] Obviously, the embodiments described above are only some of the embodiments of the present application, rather than all of the embodiments. The preferred embodiments of the present application are given in the accompanying drawings, but they do not limit the patent scope of the present application. The present application can be implemented in many different forms. On the contrary, the purpose of providing these embodiments is to make the understanding of the disclosure of the present application more thorough and comprehensive. Although the present application has been described in detail with reference to the aforementioned embodiments, for those skilled in the art, it is still possible to modify the technical solutions described in the aforementioned specific embodiments, or to make equivalent replacements for some of the technical features therein. Any equivalent structure made using the contents of the present application specification and the accompanying drawings, directly or indirectly used in other related technical fields, is also within the scope of patent protection of the present application.

[0067] This application also provides a ripple projection lamp, see Figure 4 As shown, it includes: a lamp bead board 2, a lens group 3, a lamp body 1, a detection component 5 and a controller 6.

[0070] In operation, the ripple projection lamp's lamp beads 21 stimulate light. The light emitted by each lamp bead 21, under the action of each lens 31, forms concentric circles at a predetermined distance. Under the action of the controller 6, the light alternates between bright and dark, thus creating a water ripple effect. Furthermore, when an object intrudes into the light spot, the detection component 5 detects the object. The controller 6 then controls the waveform output of the lamp bead 21 according to the ripple projection lamp control method, thereby creating different effects.

The arrangement of the color filter positioning plate 4 and the color filters 42 can change the color of the water ripple light spot, and can even cause different concentric circles to emit different colors of light, thereby enhancing the display effect. In other embodiments, the color filter positioning plate 4 and the color filters 42 can be eliminated, and the lamp beads can be configured with a multi-colored combination of lamp beads, such as RGB lamp beads, to change the color of the projector light spot.
