Description

The invention relates to lighting engineering, in particular, to the design of an LED device for painting with light in air. Such devices are used for graphic LED batons, which consist of a line of LEDs, a control circuit and a battery. A cord comes from the body of the rod, which ends with a loop for the fingers. They are rotated and perform different tricks with them. When the rod rotates in the air, a light picture is formed

You can upload any pictures, text, logos, photos to the wands through the software. During rotation, it creates the impression of pictures drawn in the air, which are clearly visible to the viewer from the side. Visible due to the inertia effect of human vision (in English the effect is called PRESENCE OF VISION). Such wands are called pixel poi, pixel poi, visual poi, picture poi and are produced by dozens of companies around the world.

So, it is known LED device for drawing with light in the air, containing an elongated body, at one end of which a cord for the user's hand is fixed in a loop and two opposite sides of which are made along the length of the body with light-transmitting sections located between sections that do not transmit light, as well as a board placed in the case in the form of a plate, on the sides of which there are mounted LED lines located opposite the light-transmitting sections of the case, a processor control unit I and the power supply located on the board (GB 2451234, А63В 15/02; А63В 67/08, published on January 28, 2009).

This decision was made as a prototype.

A feature of this known device is that the oblong-shaped body is made rigid and solid of a polymeric material (transparent polycarbonate). The need to make the case rigid is due to the fact that the LED boards located along the length of the case cannot be deformed. It is possible that during the rotation of the wand the user may touch a foreign object, as a result of which the soldering of joints may be disturbed. In this regard, manufacturers of the tubular body are made of polycarbonate, which has extremely high impact-resistant properties. In addition, when hit by himself, the user receives bruises and bumps, and therefore this type of product is used mainly by experienced professional jugglers for performances. And for this reason, they do not find application as toys for children and adults, but they could. If you put covers made of silicone or other materials softening blows on these wands, then the clarity of the images displayed in the air is immediately lost, they are significantly blurred and all the effectiveness in drawing pictures with such a wand disappears.

The present invention is aimed at achieving a technical result, which consists in increasing the safety of use by reducing the hardness of the housing and maintaining the cushioning elements to absorb shock energy.

The specified technical result is achieved by the fact that in the LED device for drawing with light in the air, containing an elongated body, at one end of which a cord for the user's hand is fixed in the form of a loop and which is made along the length of the body with light-transmitting sections, as well as a board located in the case in the form of a plate, on the sides of which are mounted LED arrays located opposite the light-transmitting sections of the housing, the processor control unit and the power supply located on the board, Nena in the form of a rigid plate, and the entire body is made of an elastically-deformable and of light-transmissive material, the body being formed with radial pattern diverging radially from it thin-walled ribs disposed on at least part of the length of the hull.

These features are significant and are interconnected with the formation of a stable set of essential features sufficient to obtain the desired technical result.

The present invention is illustrated by a specific example of execution, which, however, is not the only possible, but clearly demonstrates the possibility of achieving the desired technical result.

In FIG. 1 - shows a cross section of the housing of the LED device;

In FIG. 2 is a side view of the housing of the LED device;

FIG. 3 - shows the location of the board and the lines of LEDs in the housing of the LED device.

According to the present invention, the construction of an LED device (poi) for drawing with light in the air is considered, which is in appearance a rod attached to the hand of a user (fireman) with a cord that ends with a finger loop. Thus, by attaching the cord to the hand, the user is able to rotate the rod in the air at a speed determined by the physical abilities of the user. With quick and skillful rotation, burning poems form patterns and patterns in the air.

The claimed device (Fig. 1-3) contains an oblong shaped housing 1, at one end of which a cord (not shown) is fastened in a loop for a user’s hand. The whole body is made of elastically deformable and light transmitting material. The parts of the case located opposite the LED light sources are considered to be light-transmitting sections 2 within the framework of this application. Since we are talking about LED poi, that is, a device that glows, there is a plate 3 inside the case in the form of a plate, on the sides of which LED lines 4 are mounted located opposite the light transmitting sections 2 of the housing.

The implementation of the entire body of light-transmitting material, including in areas through which light does not pass, allows the use of modern technologies for forming bodies of polymer material. This greatly simplifies the manufacturing process of the body of a complex developed volumetric form. On the other hand, the scattering angle of the light beam of a standard miniature LED, which shines forward with a cone with a blurred side border, is about 120 °. Therefore, parts of the body that are not located in the front of the diffusion sheath are, as it were, in the shade.

The LEDs are controlled by the processor control unit (controller) connected to the power supply (the device can be charged via a mini USB port from a computer or from an adapter). These blocks are located on the board in the lower part of the case on the side of the cord (or the handle of the case). For example, the standard poi has 64 LEDs (32 on each side), the length of the luminous part is 16 cm, the total length is 27 cm. Control is carried out by three clock buttons located on the case. A long press of the central button turns the device on and off. Use the up and down buttons to change the mode.

In this part, structurally poi repeats the well-known design of poi according to the prototype.

During the rotation of the poi, there may be cases of failure of the trajectory of rotation for various reasons, which leads to the impact of the body on the user's hand. When rotating and. for example, pair performance, the likelihood of collisions of singing increases during counter rotation, as well as when performing complex elements. This is especially often the case with beginner poi rotation control training. Even with a small mass of the device, due to the high rotation speed, the force or impact power of the case is palpable enough to speak of a pain effect. Direct replacement of a solid polymer case with a soft or elastic version of its execution allows to reduce the impact of the case on the user in case of unsuccessful rotation, but at the same time the pattern is very blurred when such a rod is rotated.

The author managed to develop a soft case for graphic wands, which does not blur the picture. It consists entirely of light-transmitting material and has a special geometric shape, which at the same time dampens impacts, which will allow poi to be used as toys for children.

The first feature of the claimed device is that the board 3 is made in the form of a long narrow and rigid plate, which is the basis for placing the lines of LEDs 4 from two opposite sides of this plate (as shown in Fig. 3).

The board 3 is inserted into the housing 1, which is completely made of an elastic-flexible material. In FIG. 1 and 3 show the transverse profile of such a housing.

Another feature of such a case is that the case is made with thin-walled ribs 5 extending radially radially from it. These ribs can be located on teas of the length of the case or along the entire length of the case (to the handle or cord). A feature of the ribs is that they are thin-walled and radially directed to the central part of the body (Fig. 2). On the one hand, such radially arranged flat ribs with the root part 6 are connected to the central part of the body and therefore the elasticity and elasticity of the end part of the ribs is maximum while their root part forms power rib elements supporting the central part of the body and eliminating its excessive bending deformation. When hitting the arm, the end portion 7 of the rib bends and deforms, damping due to the elastic forces of impact energy. It is in connection with this elastic deformation of the rib that the impact energy is not transferred to the central part of the case to the extent that it could break the case or the board in it.

When hitting a hand or a foreign object, only one is exposed to deformation (as the most common case) or rarely two ribs. Their deformation looks like a deviation of the rib plane to the side. But this deformation does not provoke a change in the shape of the remaining ribs, which preserves the spatial shape of the central part of the body. Upon deformation of one or two ribs, the structure of their material undergoes compression. In this case, for the manifestation of the bending of the Central part of the body, it is necessary that the remaining ribs are stretched. The tensile deformation force in these other ribs takes place only within the framework of the elastic component, which does not lead to spatial deformation of these other ribs. This allows you to guaranteedly maintain the spatial shape of the central part of the body.

From the location of the LED rulers (Fig. 3, item 2), the observer’s eye will see a strip of translucent part, which will glow. Its width is proportional to the width of the LED. And thanks to this, when you rotate such a rod, the drawing will remain clear. And relatively long ribs made of elastic material when bent on foreign objects bend and soften collisions. To understand the dimensions: the diameter of this design is about 5 cm. The width of the board is about 15-20 mm. Proportions may be different.

The issues of constructing an electronic circuit of poi and algorithms for the formation of light pictures and drawings are not considered in the framework of this application. It is considered optimal to carry out a housing of constant cross-section along the length of the housing, or at least over most of this length (not counting the handle). But this does not limit the ability to perform the body in the form of a circus club (that is, with a small extension at the end). But in this case, the pattern becomes blurry precisely in the expansion zone. Housing options are also possible, in one of which the ribs are made of constant height (except for the zones of convergence to “no” at the ends of the housing) or the ribs can have a decreasing height in the direction from one end of the housing to the other (for example, in the direction to the handle) . The central part of the housing can be made flattened, as shown in Fig. 1 (preferred embodiment), or made oval or cylindrical or rectangular, etc. A preferred embodiment, when the ribs have a decreasing thickness in the direction from the body, but can be made constant thickness or variable in separate areas. Issues related to a specific type or type of polymeric material having elastic deformation properties and being simultaneously soft (elastic) for the execution of the body are also not considered due to the excessive abundance of such polymeric materials. You can talk, for example, about silicone polymers (silicone elastomers). In addition, modern technology allows today to combine different types of polymers during molding. This allows, for example, the central part of the casing to be made of one polymer material, and the ribs from another, which has a higher degree of elastic deformation than the central part of the casing. The housing can be made entirely in the form of a single part from one specific polymer material.

The present invention is industrially applicable, allows you to create LED poi, which can be safely used not only irradiated profession fireworks, but also as a toy for children with the aim of developing motor skills and imagination. The novelty of the invention lies in the use of an elastically deformable body with elastic radially spaced ribs, which are shock absorbers or dampers of impact energy of a rotating poi when it hits a hand or foreign object.
