Background

The laser refers to an enhanced photon beam with coherence generated by the release of radiation energy from electron transitions through atom stimulation, and has the characteristics of small light divergence, uniform propagation directivity, small light attenuation, visual sensitivity and the like. The existing laser pen can be applied to various fields such as optical fiber communication, laser spectrum, laser ranging, laser radar, laser cutting, laser disc recording, laser scanning and the like.

Traditionally, the difference of laser ranging, laser engraving and laser welding equipment mainly lies in the height of laser power, and along with the improvement of power, the energy of laser is promoted thereupon and can be applied to the sculpture and the welding operation of object. However, the existing laser ranging, laser engraving and laser welding equipment are independent and proprietary equipment, and the purpose of use of the equipment is single to the target. For example, if a high-power laser device is used to engrave and process small parts and crafts, excessive energy consumption will be caused, and the small parts and crafts are easily damaged due to the excessive laser power.

In addition, the conventional large-scale laser equipment is limited by excessive volume and weight, which is not favorable for high-degree-of-freedom operation. Therefore, the development of a multifunctional laser pen product with operation freedom has become a major development target in the future.

Detailed Description

Reference will now be made in detail to exemplary embodiments of the invention, examples of which are illustrated in the accompanying drawings. Wherever possible, the same reference numbers will be used throughout the drawings and the description to refer to the same or like parts.

Fig. 1A is a schematic perspective view of a laser pen according to an embodiment of the invention. FIG. 1B is an exploded view of the laser pointer of FIG. 1A. Fig. 1C is a partially enlarged schematic view of the first housing of fig. 1A.

Referring to fig. 1A, the laser pen 100 of the present invention is used for emitting laser light, which means that an enhanced photon beam with coherence is generated after an electron transition releases radiation energy by a stimulation atom. In detail, the existing laser transmitter is composed of three parts, namely an excitation system, a laser medium and an optical resonant cavity. The excitation system may, for example, generate optical, electrical or chemical energy and act as a means of excitation for the laser. The laser medium is a substance capable of generating laser, such as ruby, beryllium glass, neon, a semiconductor, an organic dye and the like, and when the laser medium is illuminated, electrified or chemically reacted, the laser medium can excite laser in a corresponding wavelength range. The optical resonant cavity is mainly used for enhancing the brightness and the intensity of the laser and controlling the wavelength and the transmission direction of the laser.

The laser pen 100 of the present invention includes a first housing 110, a second housing 120, a light source module 130, and a control module 140.

The first housing 110 is hollow inside and has a transmissive through-hole H. And a second shell 120 steerably coupled to the first shell 110. The second housing 120 is also hollow inside and forms an accommodating space together with the first housing 110. In the present embodiment, the first housing 110 and the second housing 120 are combined to form a pen-shaped structure, which is suitable for being held by a user.

The light source module 130 is disposed in the first housing 110 and partially penetrates through the first housing 110. The control module 140 is disposed in the second housing 120 and electrically coupled to the light source module 130. The light source module 130 has a light emitting portion 131 disposed in the transmission through hole H of the first housing 110. In the embodiment, the control module 140 is used for adjusting the power transmitted to the light source module 130. In other embodiments, the control module is used to adjust the intensity of the light energy or the chemical energy and transmit the light energy or the chemical energy to the light source module, for example, but the invention is not limited thereto.

The control module 140 transmits a specific amount of electric energy to the light source module 130, so that the laser medium in the light source module 130 is excited to emit laser light, and the laser light passes through the first housing 110 from the transmission through hole H. In addition, the control module 140 adjusts the intensity of the laser light source as the second housing 120 is turned relative to the first housing 110.

Further, a battery module 150 is disposed between the light source module 130 and the control module 140 and electrically coupled to the control module 140. The control module 140 has a control core 141 electrically coupled to the input portion 132 of the light source module 130, and when the second housing 120 is turned, the control core 141 regulates the energy output of the battery module 150. The light source module 130 has two holding portions 133, and is disposed at one end of the light source module 130 facing the battery module 150, and the input portion 132 is disposed between the two holding portions 133.

Further, the laser pen 100 of the present invention is suitable for switching to various usage modes, such as a ranging mode, an engraving mode, and a welding mode.

Referring to fig. 1A and fig. 2, for example, when the second housing 120 is not rotated and is in the initial orientation, the control module 140 is turned off, and the light source module 130 does not receive electric energy and cannot excite the laser. When the second housing 120 is turned to the first orientation relative to the first housing 110, the control module 140 is activated, and the control core 141 regulates the battery module 150 to output the first electric energy to the input portion 131 of the light source module 130, so that the light source module 130 is excited to generate the first laser L1 suitable for measuring the distance. When the second housing 120 is rotated to a second orientation relative to the first housing 110, the control core 141 of the control module 140 regulates the battery module 150 to output a second power to the light source module 130, so that the light source module 130 is excited to generate a second laser L2 suitable for engraving a workpiece. When the second housing 120 is turned to a third orientation relative to the first housing 110, the control core 141 of the control module 140 regulates the battery module 150 to output a third power to the light source module 130, so that the light source module 130 is excited to generate a third laser L3 suitable for welding a workpiece. The light source intensity of the third laser beam L3 is the highest, the light source intensity of the second laser beam L2 is the next highest, and the light source intensity of the first laser beam L1 is the lowest.

Further, the second housing 120 has a power socket 121 electrically coupled to the control core 141 of the control module 140. The power socket 121 is adapted to be electrically coupled to an external power source through a cable, and is used for supplying energy required for operation or charging the battery module 150.

Therefore, the laser pen 100 of the present invention can adjust the energy output of the battery module 150 by the control module 140 through the multi-stage steering of the second housing 120, so that the light source module 130 can excite the laser with different light source intensities, thereby satisfying different purposes such as ranging, carving and welding.

Referring to fig. 1A and 1B, the display screen 160 is disposed on the control module 130 and electrically coupled to each other, the second housing 120 has a transparent surface TS, and the display screen 160 corresponds to the transparent surface TS. In detail, the display screen 160 is used for displaying the light source intensity of the lasers L1, L2, and L3, the remaining power of the battery module 150, and the usage mode of the laser pen 100.

Finally, it should be noted that: the above embodiments are only used to illustrate the technical solution of the present invention, and not to limit the same; while the invention has been described in detail and with reference to the foregoing embodiments, it will be understood by those skilled in the art that: the technical solutions described in the foregoing embodiments may still be modified, or some or all of the technical features may be equivalently replaced; and the modifications or the substitutions do not make the essence of the corresponding technical solutions depart from the scope of the technical solutions of the embodiments of the present invention.
