Description

Technical Field

[0001] This utility model relates to a flashlight, and more particularly to a novel flashlight device, which is applied in the field of lighting technology. Background Technology

[0002] Currently, large-area camping lights and professional flashlights in the outdoor lighting field are mostly independent devices. Although some products attempt to combine the two, they generally involve serious compromises: either the flashlight mode has insufficient power, only suitable for emergencies; or the floodlight mode has a limited range, unable to replace a true camping light. The fundamental reason lies in the inherent contradiction between optical and heat dissipation structures.

[0003] Camping lights rely heavily on diffuse reflection for floodlighting, resulting in low light output efficiency; professional flashlights, on the other hand, depend on a single plano-convex lens for long-range illumination, but cannot provide comprehensive coverage. If a telescopic zoom structure is used to balance both long and short beams, the light efficiency will significantly decrease during long beams due to multiple internal reflections.

[0004] Heat dissipation design also faces a dilemma: camping lights become bulky in order to ensure heat dissipation; professional flashlights generally use all-metal bodies in pursuit of heat dissipation and strength, which is not only too expensive, but also prone to overheating when working at high power for a long time, affecting grip comfort and safety.

[0005] Therefore, existing technologies lack an integrated solution that can truly coordinate efficient dual-mode optics, high-power heat dissipation, and low-temperature grip, making it difficult to achieve both professional-grade long-range projection and wide-range efficient floodlight within a limited volume.

[0006] Therefore, a solution is needed that can simultaneously meet the optical system and heat dissipation structure requirements of both wide-area camping lights and professional flashlights to overcome the aforementioned problems. Utility Model Content

[0007] The purpose of this invention is to overcome the shortcomings of the existing technology and provide a new type of flashlight device that can simultaneously meet the optical system and heat dissipation structure requirements of a wide-range lighting camping light and a professional flashlight.

[0008] This utility model is implemented as follows:

[0009] This utility model provides a novel flashlight device, including a base, a lamp body, and a main body, wherein one side of the lamp body is connected to the base and the other side is connected to the main body;

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present utility model.

[0024] like Figures 1 to 4 This utility model provides a novel flashlight device, including a base 1, a lamp body 2 and a main body 3. One side of the lamp body 2 is connected to the base 1, and the other side is connected to the main body 3.

[0025] like Figures 1 to 4 The main body 3 has a camping light panel 31 on one side near the base 1 and a flashlight panel 32 on the other side. A cat's eye lens 6 is located on the lower side of the flashlight panel 32, used to refract and reflect the light emitted by the LEDs of the flashlight panel 32. A die-cast aluminum part 4 is located on the outer periphery of the main body 3, and the cat's eye lens 6 is located within the die-cast aluminum part 4. The die-cast aluminum part 4 is connected to the lamp body 2. The die-cast aluminum part 4 can effectively dissipate heat from the camping light panel 31 and the flashlight panel 32, providing timely heat dissipation. In this preferred embodiment, the main body 3 and the die-cast aluminum part are integrally formed and are both made of aluminum alloy.

[0026] like Figures 1 to 4 The lamp body 2 is equipped with a microprism lens 5, the inner diameter of which gradually decreases from the base 1 to the main body 3. The microprism lens 5 is used to refract and reflect the optical light emitted by the lamp beads of the camping lamp panel 31.

[0027] Furthermore, multiple cat-eye lenses 6 are provided, each corresponding to one of the LED beads of the flashlight panel 32. The LED beads of the camping light panel 31 are arranged in a ring around the main body 3 and located on the outer periphery of the microprism lens 5.

[0028] When the camping light is working, the light emitted by the LED beads in the camping light panel 31 enters through the vertical surface of the microprism lens 5. Part of the light is refracted directly from the outside of the microprism lens 5; part of the light undergoes multiple total internal reflections within the microprism lens before being refracted again; and a third part of the light is refracted through the inside of the microprism lens, reflected by the flashlight's battery compartment (or reflector) (unlabeled), and then enters from the inside of the lens before being refracted from the outside of the microprism lens. This multiple refraction and reflection process results in a more uniform light spot, effectively reducing glare.

[0029] When operating in flashlight mode, the light emitted by the LEDs in the flashlight panel 32 enters through the inner end face of the cat's eye lens 6. Part of the light is directly refracted out from the outer end face, while the rest undergoes total internal reflection on the side of the cat's eye lens and is then refracted out from the outer end face. This process of multiple refractions and reflections results in a more uniform light spot and a higher overall light output of the lamp.

[0030] This utility model fixes both the large-area lighting camping light board 31 and the professional flashlight light board 32 on the main body 3, and then dissipates heat through the connected die-cast aluminum parts 4, thereby quickly conducting away the heat generated by the light board (light beads) and having a good heat dissipation effect.

[0031] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
