Description

Technical Field

[0001] This utility model relates to the field of lighting technology, and more specifically to a media facade grille pixel light. Background Technology

[0002] In the area of ​​high-quality urban building facade lighting, with the increasing demand for creating urban nightscapes, the application of media facade lighting fixtures is becoming more and more widespread. However, existing products have many shortcomings: ① Limited product form: Most similar products on the market currently use surface-mounted LED point light sources or LED pixel light strips. This single form has limitations in meeting diverse architectural design needs and cannot fully realize the perfect integration of architectural aesthetics and lighting functions; ② Glare problem: The lamps are self-illuminating, and the light enters the eyes directly, which easily produces glare. This not only causes visual discomfort and affects the viewing experience, but may also interfere with traffic and the surrounding environment to a certain extent. Especially in areas with high requirements for the lighting environment, such as commercial areas and residential areas, the glare problem is more prominent; ③ Poor aesthetics: During the day, the pixels of the lamps are granular or strip-shaped, which destroys the overall aesthetics of the building facade and has poor coordination with the building, failing to meet the modern architectural pursuit of exquisite and harmonious appearance; ④ Uncontrollable brightness: At night, the brightness of the lamp pixels is prone to being too high, and the minimum brightness is uncontrollable. Even when the power of the lamps is reduced to the minimum, glare is still easily felt when viewed from a near-eye point, making it difficult to create a comfortable nighttime lighting environment and also hindering the precise control of lighting effects to adapt to different scene requirements. Utility Model Content

[0003] In view of this, the present invention provides a media facade grid pixel light, which is suitable for projects with media facade requirements such as high-quality urban landmark lighting, commercial advertising lighting, cultural event lighting, public art lighting, interactive experience lighting, and information display lighting. It can control light pollution and focus on the visual comfort of people in the nighttime light environment.

[0004] To achieve the above objectives, the media facade grid pixel light provided by this utility model includes a columnar lamp body shell and a light-transmitting plate disposed on the front of the lamp body shell. The lamp body shell has several layers of plates arranged in an array inside. The several layers of plates divide the interior of the lamp body shell into several three-dimensional pixel cavities. LED point light sources are provided on the plates.

[0005] Preferably, the three-dimensional pixel cavity is formed by the layer plate where the LED point light source is located, the upper layer plate, and the lamp housing.

[0006] Preferably, the three-dimensional pixel cavity illuminated by the LED point light source serves as the pixel unit of the architectural media facade.

[0007] Preferably, a wiring channel is provided inside the lamp housing on the side away from the light-transmitting plate, and the power lines and control lines of the LED point light source are laid in the wiring channel.

[0008] Preferably, the lamp housing is made of a metal frame.

[0009] Preferably, the light-transmitting panel is made of acrylic material.

[0010] Preferably, the lamp housing is provided with a curtain wall grille on the outer side and back, and the lamp housing is embedded in the curtain wall grille.

[0011] As can be seen from the above technical solution, compared with the prior art, the media facade grid pixel light disclosed in this utility model hides the light source through a specially designed three-dimensional pixel cavity, indirectly reflecting light multiple times. This allows for control of the minimum brightness of the pixels, avoids glare caused by direct light, improves the softness of video images, ensures visual comfort for near-sighted users, and allows for flexible adjustment of brightness and color temperature, vividly presenting various video materials.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. The following description of an exemplary embodiment is merely illustrative and is in no way intended to limit the present utility model or its application or use. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the scope of protection of the present utility model.

[0021] Please see the appendix Figure 1-3 This utility model discloses a media facade grille pixel light, which is used for building facade lighting and can display media video images.

[0022] like Figure 1 As shown, the media facade grid pixel light provided by this utility model includes a lamp body shell 4, a light-transmitting plate 3, a shelf 2, and an LED point light source 1.

[0023] The lamp housing 4 is cylindrical, such as a cuboid, cylinder, or other spatial geometry that can be integrated with the building facade. The light-transmitting plate 3 is installed on the front of the lamp housing 4. The layer plate 2 has several layers and is arranged in an array inside the lamp housing 4. The layers of layer plate 2 divide the interior of the lamp housing 4 into several three-dimensional pixel cavities 5. That is, the three-dimensional pixel cavity 5 is formed by the layer plate 2 where the LED point light source 1 is located, the upper layer plate 2, and the lamp housing. Each layer plate 2 is provided with an LED point light source 1, so that the LED light source 1 is installed in the three-dimensional pixel cavity 5 composed of a metal frame. The light is reflected multiple times in the three-dimensional pixel cavity 5. The three-dimensional pixel cavity 5 illuminated by the LED point light source 1 serves as the pixel unit of the building media facade.

[0024] like Figure 2 As shown, in order to improve the neatness and safety of use, a wiring channel is provided on the side of the lamp housing 4 away from the light-transmitting plate 3. The power line and control line 7 of the LED point light source 1 are laid in the wiring channel to avoid external wiring and messy wires being scattered in various places, which could lead to safety hazards and affect the media display effect of the light presentation.

[0025] It should be noted that the lamp body shell 4 is made of a metal frame to improve stability and safety, and the light-transmitting plate 3 is made of acrylic material, which can better present the lighting effect of the LED point light source 1.

[0026] like Figure 3 As shown, in use, the lamp body housing 4 is embedded in the curtain wall grille 6, that is, the curtain wall grille 6 is set on the sides and back of the lamp body housing 4. The lamp body housing 4 and the curtain wall grille 6 are fixed together by screws. According to the area of ​​the building facade and the lighting requirements, the quantity and specific shape and position parameters of this utility model can be adaptively adjusted to achieve a better media display effect.

[0027] It should be noted that all connections of the components in this utility model are sealed with waterproof sealing rings to prevent moisture intrusion and extend the service life of the lamp.

[0028] The working principle of the grid pixel light of this utility model is as follows:

[0029] Each three-dimensional pixel cavity 5 serves as a pixel unit of the building's media facade. By controlling the brightness and color of each LED point light source 1, the overall media facade of the building is constructed. Furthermore, the control system plays specific video footage, enabling the building to serve as a medium for cultural dissemination at night. Through multiple comparative experiments, the surface reflectivity of the reflective cavity and the transmittance and transparency of the light-emitting surface were confirmed, ultimately achieving a surface brightness of approximately 25 cd / ㎡ for the luminaire.

[0030] It should be noted that all directional indicators (such as up, down, left, right, front, back, etc.) in the embodiments of this utility model are only used to explain the relative positional relationship and movement of each component in a certain specific posture (as shown in the figure). If the specific posture changes, the directional indicator will also change accordingly.

[0031] In this utility model, unless otherwise explicitly specified and limited, the terms "connection," "fixing," etc., should be interpreted broadly. For example, "fixing" can mean a fixed connection, a detachable connection, or an integral part; it can mean a mechanical connection or an electrical connection; it can mean a direct connection or an indirect connection through an intermediate medium; it can mean the internal communication of two components or the interaction between two components, unless otherwise explicitly limited. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0032] Furthermore, if the embodiments of this utility model involve descriptions such as "first" or "second," these descriptions are for descriptive purposes only and should not be construed as indicating or implying their relative importance or implicitly specifying the number of technical features indicated. Therefore, a feature defined with "first" or "second" may explicitly or implicitly include at least one of those features. Additionally, the meaning of "and / or" throughout the text includes three parallel solutions; for example, "A and / or B" includes solution A, solution B, or a solution where both A and B are satisfied simultaneously. Furthermore, the technical solutions of the various embodiments can be combined with each other, but this must be based on the ability of those skilled in the art to implement them. When the combination of technical solutions is contradictory or impossible to implement, it should be considered that such a combination of technical solutions does not exist and is not within the scope of protection claimed by this utility model.
