Description

Luminescent projectile {LIGHT EMITTABLE PROJECTILE}

The present disclosure relates generally to light emitters, and more particularly to light emitting projectiles suitable for projection.

This section provides background information related to the present disclosure which is not necessarily prior art.

However, despite the fact that the light emitting ball 1 is a projecting body, the masses are arranged in the ball without being too balanced, and thus cannot be regarded as suitable for projection.

This will be described later in the Specification for Implementation of the Invention.

The present disclosure will now be described in detail with reference to the accompanying drawing (s).

FIG. 2 is a view illustrating an example of a light emitting projection body according to the present disclosure, and includes a reference point 10 (a point) and a rear surface located near a front face 21a located far from the reference point 10 ( A surface 21 having a rear face (see FIG. 4), a light emitting portion 31 disposed on the front surface 21a, and a mass 41 disposed on the rear surface 21b and having a power supply portion; mass) is shown. The surface 21 may be made of a printed circuit board, and in this case, since it does not require a separate electric wire for supplying power to the light emitting part 31, there is an advantage in projection. The projected object can be irradiated omnidirectionally by being composed of at least four sides 21, 22, 23, 24. The light emitting unit 31 preferably has a weight that does not significantly affect the low power consumption and the projection movement, for example, a light emitting diode (LED). The power supply portion has a larger weight than the light emitting portion 31 and greatly affects the projection movement. Therefore, since the mass 41 having the power source can bring eccentricity in the projection motion, it is necessary to be disposed as close to the reference point 10 as possible in the projected structure. In addition, the mass 41 including the power supply portion needs to be positioned so as to span the virtual line L connecting the center C of the surface 21 from the reference point 10. This is because a large eccentricity can be brought in spite of being located in the rear face 21b when the mass 41 is excessively out of the center C. For example, a coin type battery may be provided on at least four sides 21, 22, 23, and 24. In this case, it is more preferable to arrange the center of the coin type battery (for example, a watch and a battery used in an automobile door lock switch) and the center C. Of course, it can be positioned away from the center (C) due to space constraints inside the projected object.

3 is a view showing another example of the light emitting projection body according to the present disclosure, and further includes a hollow housing 50. For example, the housing 50 may consist of two parts 50a and 50b, which will minimize the occurrence of eccentricity by the housing 50 or the occurrence of additional thickness at the joints through shape engagement or threaded engagement. Can be combined and decoupled. In addition, the housing 50 may have a function as a lens and increase the efficiency of light emission. Therefore, the housing 50 may be in any form as long as it protects the light emitting projection or has a lens function. However, it is desirable to have a form and / or assembly method that does not cause eccentricity in the projection movement. In addition, by using the vertices 21c, 22c, 23c, and 24c formed by the at least four surfaces 21, 22, 23, and 24 to engage with the housing 50, by removing the separate coupling member, The occurrence can be further reduced. This coupling can be achieved by (1) simply size the at least four sides 21, 22, 23, 24 to the inner dimensions of the housing 50 (eg 7 cm in diameter), or (2) the coupling grooves in the housing 50. It can be made easily by forming the 51 or (3) by providing the spacer 52 having elasticity and / or adhesion to the vertices 21c, 22c, 23c, 24c and having a predetermined length.

4 is a diagram illustrating an example of a rear surface of the light emitting projection body according to the present disclosure, and the mass body 41 is provided on the rear surface 21b. The mass body 41 may include, for example, a supplementary weight corresponding to the power supply unit 41a or the power supply unit for preventing eccentricity (for example, a mass mass having the same weight as the power supply unit). The mass body 41 can fix the power supply part 41a to the rear surface 21b using the holder 41b. The holder 41b may be composed of, for example, a mass insertion frame 41c and a mass fixing arm 41d. Preferably, these masses are also appropriately distributed.

FIG. 5 is a view showing another example of the rear surface of the light emitting projection body according to the present disclosure. As the mass body 41, a switch 41e for controlling electrical connection between the power supply portion 41a and the light emitting portion 31 is provided. The switch 41e may include a chip for wireless transmission and reception (eg, a ZIGBEE chip), a micro control unit (MCU), an electric element, and the like. By using a chip for wireless transmission and reception, structures required when using a mechanical switch can be replaced with a lightweight semiconductor chip, thereby greatly reducing the eccentricity. On the other hand, when the weight of the switch 41e does not significantly reach the power supply unit, it can be adjusted using the auxiliary weight 41f. Preferably, the switch 41e and / or the auxiliary weight 41f are disposed in the constant area R at the center. More preferably, the size of the region R does not equal to or deviate from the region where the mass 41 of FIG. 4 is located. This arrangement must take into account the size constraints of the components constituting the switch 41e. Like the mass 41 in FIG. 4, the region R is preferably positioned to overlap the imaginary line L. As shown in FIG.

6 is a view showing another example of the rear surface of the light emitting projection body according to the present disclosure, and the mass insertion frame 41c is provided on the rear surface 21b. The mass insertion frame 41c can be used to help control the weight and position the switch 41e. That is, by using the same structure on the rear surfaces, the eccentricity can be reduced. If necessary, an auxiliary weight 41f may be added.

Various embodiments of the present disclosure will be described below.

(1) In the case where the face 11 and the face 12 become a printed circuit board, connector pins 15 (see FIG. 7) can be used for their electrical connection and fixing. On the other hand, the connector pin 15 is removable from the printed circuit board, thereby facilitating replacement of the power supply.

(2) At least four sides may form a tetrahedron. This can result in uniform irradiation in all directions and reduction of eccentricity. Those skilled in the art should note that the light emitting projection body according to the present disclosure can be applied to the reduction of the eccentricity of the polyhedron or three-dimensional in which omnidirectional irradiation is possible in addition to the tetrahedron.

(3) At least four surfaces may be formed concave toward the reference point. This allows the mass to be positioned closer to the reference point. Those skilled in the art should note that at least four sides of the light emitting projection body according to the present disclosure may not necessarily be flat surfaces.

(4) The reference point may have an auxiliary weight. This helps with low center of gravity design of the projectile. This auxiliary weight can be easily fixed by a connector or the like extending from the vertices.

(5) The use of mating and disengaging surfaces (21, 22, etc.) and the housing allows replacement of the power supply. This is possible by the use of two parts 50a, 50b of the housing, the use of connector pins 15 and the like. This configuration means that the design and creation of a conventional projectile suitable for the golf ball shown in FIG. 1 differs from the present disclosure.

(7) A light emitting structure in which faces 21, 22, 23, and 24 surround a reference point with a vertual plane made of wire, not a physical and entangible plane, such as a printed circuit board.

According to one light emitting projection body according to the present disclosure, it is possible to reduce the eccentricity of the projection movement.
