Description

Human body thermal power generation handheld lighting device

The present invention relates to a hand-held illuminating device that can provide power to a small light source by means of human body heat energy.

"Laser Pen" is a portable, portable optical product that produces a low-power concentrated laser beam. It has been used for many years and is commonly used for indication purposes; for example, in class, conference briefing, ... In other occasions, the beam generated by the laser pen can be projected to the desired position, so that others can quickly understand the subject mentioned by the lecturer or the briefer.

The conventional laser pen structure generally has a laser unit module and a battery disposed inside a tubular body, and a switch is disposed on the body, and when the switch is pressed, the battery can be supplied with current to the laser unit module. The group is activated to generate a bundle of laser light and to emit laser light from one end of the body.

Another type of conventional laser pen is to mount the laser unit module and the battery inside the real pen. When the switch is pressed, the laser light can be projected from the second end of the pen. The first end is provided with a refill containing ink to maintain the original writing function of the writing instrument.

Another conventional laser pen is installed in addition to the laser unit module and the battery. Inside the real pen, the generated laser light can be projected from the second end of the pen, and the first end of the pen is provided with a touch pen reel, which can be used to operate the electronic touch screen.

In addition, it is also common to combine a light-emitting diode (LED) with a stylus to make the stylus have a lighting function at the same time.

Regardless of which of the above-mentioned laser pens, it is necessary to configure a battery to supply current to the laser unit to emit light. Therefore, in addition to the cost of purchasing the battery, the discarded battery also has environmental problems.

The purpose of this creation is to solve the problem that conventional hand-held lighting devices such as laser pens need to be equipped with batteries to operate, which is costly and unfavorable to environmental protection.

The feature of the present invention is that a thermal energy generating unit is disposed in a heat-conducting body, and the body is provided with a light source unit, and the user transmits the body temperature to the thermal power generating unit to generate electric power while holding the body, and the generated Power is then conducted to the light source unit to cause the light emitting element to emit light.

Based on this, the technical means of the present invention includes: a body, the system is made of a metal material capable of conducting heat, and at least one thermal power generating unit is disposed therein; and a light source unit is disposed on the body, The light source unit has a light emitting component and a circuit board electrically connected to the light emitting component and the thermal power generating unit; wherein the thermal power generating unit generates heat after receiving heat energy of the human body temperature, and transmits the power to the circuit board The circuit board controls whether the light emitting element emits light or does not emit light.

In a preferred embodiment, the body is provided with a switch electrically connected to the circuit board, and the switch is used to control a current path or a current interruption between the circuit board and the light emitting element.

Preferably, the present invention uses LEDs as the light-emitting elements.

In another preferred mode, the present invention employs a laser generator as the light-emitting element.

The first figure is a plan sectional view showing the overall structure of the present creation; and the second figure is a plan sectional exploded view showing the main component combination relationship of the present creation.

In order to further understand the features, technical means, and specific objectives and functions of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

The first and second figures show a plan sectional view and a cross-sectional exploded view of the overall structure of the present hand-held light-emitting device, and include a tubular body 1 which is preferably made of a metal material capable of conducting heat. In the form of a pen tube, a switch 5 that can be elastically pressed is disposed at an appropriate position of the body 1; the inside of the body 1 is hollow, and at least one thermal power generating unit 2 is disposed inside the body, and the thermal power generating unit 2 is provided After the inside of the body 1 is in contact with the inner wall surface of the body 1, so that heat conducted through the body 1 can be received; the thermal power generating unit 2 is a small power generation system that can transfer the heat to electric power after receiving the heat, It is a conventional device, so it does not explain its power generation principle and further technical features.

One end of the body 1 is combined with a light source unit 3 having a light-emitting element 31. A circuit board 4 is disposed between the light source unit 3 and one end of the body 1. The circuit board 4 and the light-emitting element 31 and the switch 5 are The electric wires are electrically connected, and the circuit board 4 and the thermal power generation unit 2 are also electrically connected by wires; in addition, one end of the outer casing of the light source unit 3 is provided with corresponding light The hole of the element 31 in the direction in which the light is projected; the light-emitting element 31 may be an LED or a laser generator.

When the present invention is required, the user conducts the body 1 while transferring the body temperature of the human body to the body 1. The heat of the body temperature is transmitted to the thermal power generation unit 2 via the body 1, and the thermal power generation unit 2 transfers the thermal energy to the electric power. Conducted to the circuit board 4, the user operates the switch 5 to control the current path or current interruption between the circuit board 4 and the light-emitting element 31. When the current path is the light-emitting element 31, the light-emitting element 31 emits light, and when the current is broken, the light is emitted. Element 31 does not emit light.

The above-described embodiments are merely illustrative of one embodiment of the present invention, and the description thereof is more specific and detailed, but is not to be construed as limiting the scope of the present invention. It should be noted that a number of variations and modifications may be made by those skilled in the art without departing from the inventive concept, which are all within the scope of the present invention.
