1) Field of the Invention
This invention relates to a light-emitting device, in particular, to a device that can be easily attached to and detached from an object, adding light-emitting function to the object, so as to increase practicability of the object.
2) Description of the Prior Art
With the development of science and technology in various industries and commerce, the added values of commodities have been diversified by combining respective singular functions of different objects onto one object in order to meet growing consumer needs. For example, a light-emitting device is commonly attached to an object, such as an umbrella, a baton, a pole, etc., for convenient use.
Generally, a light-emitting device can be used either independently or in combination with another object. Usually, an independently used light-emitting device is like a flashlight, which cannot be installed onto another object; therefore, the practicability thereof is decreased. On the contrary, a light-emitting device used in combination with another object, such as an umbrella, a baton, a pole, etc., not only retains the effect of that object itself, but also adds the light-emitting effect and function, so as to increase the practicability of that object. However, as such a light-emitting device fits only to one of the afore-mentioned objects, but not others, the practicability thereof is still limited.
In view of the foregoing drawbacks, the present invention described herein provides a more practicable detachable light-emitting device with a wider application.
The present invention mainly comprises a head connecting portion disposed on one end of a light-emitting device; a base is integrally formed with the upper portion of the head connecting portion and a supporting portion is disposed on the base enabling a circuit board to be fixed on the supporting portion; in addition, the circuit board electrically connects a switch, a power outlet for holding battery and at least one luminous body on the circuit board; a light permeable portion made of light permeable material sleeves with the upper portion of the base, thereby enabling the circuit board to be contained inside the light permeable portion and a push-button end of the switch protrudes outside of the light permeable portion; a bonnet is disposed on the upper portion of the light permeable portion and over the push-button end of the switch; a push-button portion is disposed on the other end of the light-emitting device via a lid, where the lower portion of the push-button portion has a power button disposed thereon; a spring is disposed between and against the bonnet and the power button for providing restorable elastic strain for the push-button portion.
The present invention further comprises,
a light permeable portion is made of light permeable material and integrally formed with the upper portion of the base; a circuit board is disposed on the upper portion of the base to electrically connect a switch and at least one luminous body; a power outlet for holding at least one battery is contained inside the base to connect the bottom of the circuit board; in addition, a bonnet is disposed on the upper portion of the light permeable portion, protruding over a push-button end of the switch outside the light permeable portion;
a head connecting portion is disposed on one end of the light-emitting device, an upper portion of the head connecting portion and a base can be integrally formed, in addition, the head connecting portion has a socket joint disposed on the lower portion thereof;
a push-button portion is disposed on the other end of the light-emitting device covered by a lid and has a power button socket disposed on the lower portion thereof; and
a spring is disposed between and against the bonnet and the power button for providing upward restorable elastic strain for the push-button portion an upward restorable elastic strain.
The light-emitting device of the present invention can be easily attached to and detached from an object, thereby adding light emitting effect and function to the object.
The main objective of the invention is to enable a light-emitting device to be easily attached to and detached from an object (such as an umbrella, a cane, or a baton) based on the component assembly in the preceding paragraphs, thereby adding light-emitting effect and function to the object, so as to increase the practicability of the object.
Further aspects, objects, desirable features, and advantages of the invention will be better understood from the detailed description and drawings that follow in which various embodiments of the disclosed invention are illustrated by way of example. It is to be expressly understood, however, that the drawings are for the purpose of illustration only and are not intended as a definition of the limits of the invention.
With reference to
a head connecting portion 1 disposed on one end of the light-emitting device, an upper portion 11 of the head connecting portion 1 and a base 2 are integrally formed, in addition, the base 2 has a circuit board 3 fixed on a supporting portion 23 thereof, moreover, the circuit board 3 electrically connects a switch 31, a power outlet 32 for holding battery 35 and at least one luminous body 33 on the circuit board;
a light permeable portion 4 made of light permeable material sleeves with the upper portion 21 of the base 2 allowing the circuit board 3 to be contained inside the light permeable portion 4, and a push-button end 311 of the switch 31 protrudes outside of the light permeable portion 4, in addition, a bonnet 5 is disposed on an upper portion 41 of the light permeable portion 4 and over the push-button end 311 of the switch 31;
a push-button portion 9 is disposed on the other end of the light-emitting device via a lid 10, wherein a power button 8 is disposed on the lower portion of the push-button portion 9; and
a spring 7 is disposed between and against the bonnet 5 and the power button 8 for providing upward restorable elastic strain for the push-button portion 9a upward restorable elastic strain.
The light-emitting device of the present invention can be easily attached to and detached from an object (such as an umbrella, a cane, or a baton) according to the foregoing component assembly design, thereby adding light emitting effect and function to the object.
In view of the foregoing, the bottom of the head connecting portion 1 has a socket joint 12, which firmly connects to a corresponding object (such as an umbrella, a cane, or a baton). In addition, the circuit board 3 can be an Integrated Circuit (IC) board or a LED (Light-Emitting Diode) board. The power outlet 32 can hold at least one battery 35. The exterior of the bonnet 5 forms a protruding end 51, which protrudes through a spring 7 and props up against a protrusion 82 disposed on the bottom of the power button 8. A waterproof washer 6 may additionally be disposed on the bonnet 5 to prevent rain or liquid permeation.
When assembling the preferred embodiment of the present invention, first of all, external threads 111 on the upper portion 11 of the head connecting portion 1 and internal threads 221 inside bottom 22 of the base 2 are screwed together; three fixed apertures 34 on the circuit board 3 are then respectively fixed with three fixed ends 231 on three supporting portions 23; and then external threads 211 on the upper portion 21 of the base 2 and internal threads 421 on the interior 42 of the light permeable portion 4 are screwed together, allowing the switch 31 on the circuit board 3, the power outlet 32 for placing the battery 35 and three luminous bodies 33 to be placed in the light permeable portion 4. The push-button end 311 of the switch 31 protrudes through a hole 412 on the upper portion 41 of the light permeable portion 4. Subsequently, the bonnet 5 is assembled over the push-button end 311 of the switch 31 and a waterproof washer 6 is further placed on the bonnet 5. The spring 7 is then disposed on the waterproof washer 6, and the power button 8 is disposed on the spring 7, thereby allowing a protruding end 51 of the bonnet 5 to protrude through the spring 7 and propping up against a protrusion 82 on the bottom of the power button 8.
