The illumination helmet of the present invention is based on a support cap for wearing on the top of the head and an outer cap mounted on the support cap and fixedly coupled to the support cap. In order to achieve optimal ventilation of the head of the lighting helmet wearer, the supporting cap body is provided with a plurality of first through holes which are located in the holes or grooves on the outer surface of the supporting cap and facing the outer cap body. The inner surface.

The front portion of the outer cap body is provided with at least a second through hole, and each of the second through holes is in communication with the corresponding groove and the first hole in the support cap. The rear portion of the support cap and the outer cap form an equal number of assembly passages in the holes or grooves of the support cap, the passages opening in the rear region of the illumination helmet, thereby providing the first hole, the second A support having a venturi effect is formed between the support cap of the bore and the groove and the outer cap, the passage being in communication with the interior environment defined by the support cap to communicate with the head of the lighting helmet wearer.

The support cap is generally cup-shaped, and in use, the concave portion of the support cap is oriented downward. The cap extends longitudinally and is comprised of two opposing portions that are symmetrical with respect to a plane that is perpendicular to the plane that supports the illumination helmet. The inner surface of the cap defines a cavity in the central projection that extends between the aperture and a portion of the trailing edge of the cap.

The cavity has a region at its central portion which has a cross-sectional area smaller than that of other regions of the cavity to form a constricted portion. Further, in a portion connecting the central projection and the hemispherical region, the inner surface of the outer cap body is provided with two projections, so that when the outer cap body is mounted to the support cap body, the two projections can be respectively assembled to Supporting the recessed portion on the cap body.

When using such an illuminated helmet, air enters the lighting helmet through the through hole in the outer cap, then flows into the hole in the support cap and passes through the wearer's hair, cooling the top of the head and allowing the sweat to evaporate all the time, with the top of the head and The holes are formed by fitting the grooves into the area of the illuminated helmet provided with holes. The air flows out of the lighting helmet not only through the holes, but also from the left to the right through three channels from the lighting helmet, three of which are formed in the rear region of the lighting helmet by joining the various surfaces of the cap body together. of.

In this way, the air passing through the hair of the wearer of the lighting helmet can easily flow out of the lighting helmet, from And to ensure the effective circulation of air in the wearer's head. Thus, since the lighting helmet is very robust and has an aerodynamic structure, the above objects of the present invention are achieved to ensure good ventilation of the wearer's head.

The lighting helmet disclosed by the invention is a high performance composite helmet, which greatly improves the protection performance of the helmet. T1000 material with high temperature resistance, high pressure resistance, ultra high vacuum, high specific strength and high specific stiffness, carbon fiber with 7000MPa tensile strength and tensile modulus of 540GPa, and high temperature resistant metal-based or ceramic matrix composite .

In another embodiment, the driver's head is safe in the event of an impact. The helmet is mainly composed of carbon, Kevlar fiber and polyethylene. The introduction of carbon is mainly for reinforcement and guarantees the high strength of the helmet; the role of Kavlar fiber is for fire prevention; and the purpose of polyethylene is to ensure the helmet. No deformation occurs even when the temperature varies widely. The main function of the buffer layer is to absorb external impact forces. If the helmet with a hard outer casing does not have a buffer layer, when an external impact is encountered, the external force will directly act on the head through the hard outer casing, causing damage to the head. Therefore, the thickness of the buffer layer and the quality of the material determine the buffering capacity of the helmet. The buffer layer is mainly made of a foamed styrene material.

In another embodiment, the helmet body is injection molded by a flame-retardant polymer, the helmet body has a single rib structure, and the cap body is connected by a buckle. The cap holder group is composed of a cap hoop, a cap holder, an amplitude modulation belt, a buffer layer, and the like, and a double-buffer layer is formed by a Han-layer webbing to increase the buffer absorption performance of the external impact. The cap is adjusted by a ratchet, and an amplitude-adjusting top pad is provided to improve the wearability and protection of the cap holder. The adjustable lower strap is connected to the helmet in a Y-shape. ·

In another embodiment, the exterior of the helmet body is woven with a weft-knit biaxial multilayer backing (MBWK) fabric. The braided biaxial multi-layer woven fabric evolved from a conventional weft-knitted weft-inserted fabric. The most essential change in the MBW fabric structure compared to warp-knitted axial fabrics is the organization of the binding system. The warp-knitted axial fabric bundling system uses a flat or braided structure, and the MBWK fabric bundled coil structure uses a ribbed structure. The warp and weft high performance fiber lining is 0° / 90. Vertically aligned, the multi-layer yarn is bundled into a unitary body by a bundle of yarns of a certain strength. Compared with the woven fabric, the tissue point is significantly reduced, and the lining yarn in the fabric is in a straight state, so that the tensile deformation property is low, and the mechanical potential of the high-performance fiber can be fully utilized. The utilization rate of the yarn in the MBWK fabric is over 90%, while the plain weave fabric is only about 70%. Compared with the stitchbonded fabric, MBWK fabric also has good damage tolerance and fatigue resistance, and avoids the in-plane fiber damage and in-plane mechanical strength of the stitchbonded fabric during the stitching process. Defects in the decline of force. The weft-knitted ribbing bundling system of MBWK fabric imparts a certain elasticity to the fabric, overcoming the tempering limitations of woven fabrics, warp knits and UD laminates. The bundled coils make the linearly arranged yarn lining system relatively fixed, ensuring the stability of the high-performance fiber orientation; and the layers of the lining yarn form a unified overall structure, which improves the splitting resistance performance between the layers. When the tension of the binding yarn is too large, the shape of the yarn is easy to be concave, and the edge of the yarn lining system is no longer a smooth straight line, and the stress will concentrate at the deformation, thereby weakening the bearing capacity of the yarn and affecting the ballistic impact response performance of the fiber. Reinforced fabrics for ballistic helmets are mainly organic fabrics, UD materials and knitted axial fabrics. In the woven fabric, warp and weft, press 90. Interwoven, when the shear deformation, the angle between the warp and weft yarns can not be 0 ~ 90. There is an arbitrary reduction, and there is a shear critical angle. When molding, once the angle between the warp and weft yarns is smaller than the critical shear angle, the fabric will wrinkle. There is also a wrinkling problem in the unidirectional (UD) fabric molding. The flattened or braided structure of the warp-knitted axial (biaxial or multi-axial) fabric binding system significantly reduces the inclination and rotational freedom of the warp and weft yarns. After the fabric is molded, serious problems will occur. Arching phenomenon. MBWK fabric has rib structure due to the binding system. The fabric has certain elasticity and can be formed at one time without folding or stitching. The helmet surface is smooth and can be molded into a complex curved surface shape, which is beneficial to enlarge the protective area of the helmet. MBWK fabric has excellent molding performance and simple molding process, which is beneficial to changing the traditional manual paste forming method and improving the molding working environment, and can significantly improve the molding efficiency of the police bulletproof helmet.

In another embodiment, the outer casing portion is made of a material such as a thin solid plastic. The outer casing section provides structural integrity and support. Although the outer casing portion can be manually operated in response to the force or pressure of the human hand, when the pressure of the human hand is removed, it usually returns to its original configuration. Therefore, it is desirable that the outer casing portion be flexible or manually adjustable while still exhibiting sufficient structural characteristics to maintain its desired configuration during use. In general, the plastic frame has a thickness of about 0.2 mm to 5 mm, and can be constructed to be not excessively thin and light, and to maintain its predetermined shape without being subjected to manual force or pressure. The outer casing portion may be made of, for example, a plastic such as polypropylene having a thickness of 0.5 to 1.5 mm. The outer casing portion has a matte surface on at least one side to avoid reflections that may interfere with the user's field of view.

The knit fabric is generally inherently or wholly porous, and this porosity allows air to escape from the interior gas space through the reticulated porous fabric. The fabric can be obtained by weaving one or more yarns in a manner that forms a series of interlocked or interlocking loops in the fabric. Knitted fabrics differ from single woven or plain woven fabrics in that the yarn is 90 degrees or substantially perpendicular to it in a single woven or plain woven fabric. The yarn is staggered up and down. Thus, the knit fabric comprises or consists essentially of a series of interlocking rings of one or more yarns, wherein the yarns do not have to intersect each other vertically in a manner that is staggered above and below. This fabric structure tends to make the knit fabric inherently more flexible than a single woven fabric, which improves comfort and fit. Knitted fabrics are also typically capable of being stretched in two major dimensions, primarily two-dimensional structures. Therefore, the knitted fabric tends to be more malleable or suitable, which allows the device to fit snugly and fitably on the wearer's head.

"Elastic yarn" is used to improve the "stretchability" of fabrics. "Flame-retardant yarns" make helmets resistant to aging caused by burning or overheating, while "comfort yarns" improve the head of men's helmets. "Feeling". As noted above, the improved stretchability feature allows the helmet to fit snugly against the various sized heads. The elastic yarn may be mainly made of a polymer such as polyurethane, or may be made of, for example, modified acrylic, latex or a combination thereof. The flame retardant yarn may be made of an inherently flame retardant material, or the material may be chemically treated to impart flame retardancy to the fabric. It is generally preferred to have a flame retardant material because it has better washability. Examples of the flame-retardant yarn may include oxidative heat-stable polyacrylonitrile, flame-retardant polyester-modified acrylic resin, and nylon. The comfort yarn helps the fabric to provide a soft feel upon contact, thus making the fabric feel comfortable when in contact with a person's face. One example of a comfort yarn that can be used in the device of the present invention is cotton. Other suitable comfort yarns may include polyester, acrylic, rayon, and wool. Elastic yarns, flame-retardant yarns, and comfort yarns can generally be used in fabrics at a percentage of about 0 to 20%, 30 to 100%, and 0 to 70%, respectively, based on the weight of the fabric. Preferably, the elastic yarn, the flame-retardant yarn, and the comfort yarn are used in amounts of about 1 to 10%, 35 to 70%, and 30 to 60%, respectively. If the flame retardant yarn is combined with the comfort yarn, they are used in an amount of about 80 to 99% by weight.

The fabric can also be of substantially any color and can be made from dyed polymeric materials such as polyester, modified acrylic, or mixtures or blends of these polymeric materials with dyed natural yarns. Regarding its thickness, the thickness of the fabric may be a single strand of 1/50 yarn, but may be, for example, about 1/70 to 1/10 yarn, but preferably about 1/60 to 1/30 yarn, but it is also Suitably have other thicknesses. The fabric may be in a non-folded combination, i.e., a knit layer may be about 0.3 to 3 mm thick, preferably about 0.7 to 1.5 mm thick, although larger or smaller thicknesses may be used as long as the device allows for sufficient fluid flow. . The knitting device can be made from 1 to 10 yarn ends, preferably from about 1 to 5 yarn ends. The number of yarn ends is the number of yarns woven together. The elastic yarn can be woven with the combined yarn to provide a stretchable elastic fabric that is both comfortable and flame retardant. The elastic fibers can be, for example, modified acrylic, latex or a combination thereof.

The outer casing portion of the helmet portion can have a first region and a second region that define regions having a first permeability and a second permeability. The first permeable region may have greater resistance to airflow (or a higher pressure drop across it) so that air exiting the interior gas space is more easily directed through the second permeable region. Generally, there are more elastic yarns in areas with higher permeability. The beneficial effect of differentiation is that it allows selective drainage of fluid in the airflow across the inside, and it allows the guided fluid in front of the wearer's head to help wick away heat.

In another embodiment, the illumination helmet of the present invention can be adjusted to accommodate different head configurations and to optimize user comfort and protection. The outer casing portion is rigid and is preferably made of a vibration-proof material. Preferably, the material selected is sufficiently rigid to distribute the vibrational shock throughout the foam pad. The material is, for example, from polycarbonate (PC), a copolymer formed from acrylonitrile, butadiene and propylene (referred to as ABS), a long-fiber thermoplastic or thermosetting matrix compound, or even aluminum. The thickness of the outer casing portion is preferably about lnrni to 3 mm. The outer casing portion is manufactured by an industrially known method, particularly by injection, thermoforming, compression or drawing. For example, the crown portion can be injected directly onto the cap and the other portions bonded or welded to the cap. In the same way, it is also possible to weld, stitch, or even bond all of the outer casing parts or a part of the outer casing parts.

In another embodiment, the illumination helmet differs from the previous embodiment in the shape of the outer casing portion. These outer casing portions can include edges having a thickness less than or equal to the thickness of the outer casing portion and designed to block the separation gap between the outer casing portions to prevent any sharp objects from penetrating and to enhance user safety. For example, the edges are stacked above or below the adjacent outer casing segments and they cooperate with these adjacent outer casing portions to optimize user safety. .

In another alternative embodiment, the outer casing portion is thermoformed in a single plate to form a single outer casing that completely covers the foam pad 7, and a region of greater thickness constitutes the outer casing portion, and a region of lesser thickness constitutes the outer casing portion. Less material bridging parts. The thinner areas form a hinge for the hinged outer casing portion and are capable of meeting different safety standards.

In another alternative embodiment, the cap is made of fabric or elastomer. It is preferably perforated to enhance breathability. The cap is preferably made of a high tough polyester type: breathable, perforated fabric. In a specific example of a flexible and resilient cap, the elasticity must be made to avoid that the outer casing portions are spaced apart too Far and possibly loosening the outer casing portion and the cap. This feature is important, especially when the helmet is impacted by a sharp object.

In another embodiment, the helmet advantageously includes a strap that is securely fastened to the cap. Lighting heads Helmets include jaw belts and suspension belts. The slings enclose the foam padding through the top and back to ensure good safety and good detachment resistance. The jaw band and the heald strap are for example stitched or riveted to the cap. The foam pad is made of a semi-rigid honeycomb material that absorbs the compressive impact energy and can be flexibly deformed by its material and its geometry to maximize the fit of the user's head shape when wearing the helmet. Therefore, the outer casing portion is equivalent to a true deformable protective casing.

The foam pad is manufactured, for example, by dicing from a polymeric foam material; for example, expanded polypropylene; The foam has a thickness of about 18 mm to 22 mm and a density of about 80 g/l to 100 g/l. The vibration absorbing properties of this foam have a memory effect that allows it to return to its original shape after vibration. After the impact acts on the helmet, the foam pad returns to its original shape. Preferably, the foam pad comprises a plurality of slits in its wall thickness. Preferably, the slit is offset relative to the gap separating the outer casing portions, primarily for safety reasons, and prevents any sharp objects from penetrating. The primary function of the slit is to promote deformation of the foam pad when the lighting helmet is worn on the user's head. They also enable good circulation of air collected by the vents in the crown portion. The vent is preferably a slit that is positioned to face the foam pad.

In another embodiment, the lighting helmet advantageously includes a headband adjustment device designed to adjust the size of the lighting helmet and better distribute the compression at the level of the user's headband to optimize his/her Comfort. Preferably, the adjustment means is inserted into the occipital portion and such that all of the outer casing portions of the headband constituting the illumination helmet; i.e., the occipital portion, the anterior portion and a portion of the lateral side portions; are capable of moving toward each other. The adjustment device is formed by a quick lap strap or a self-clamping strap to connect the occiput portion and the two lateral side portions.

In another alternative embodiment, the adjustment device is adjusted by a multi-directional fastening system. The adjustment device includes a strap that is wrapped around an embossing knob that is preferably secured to the occiput portion. The tie causes the outer casing portions of the headband forming the lighting helmet to be interconnected and passed through a tensioning point which is preferably disposed on the edge of the outer casing portion. The operation of the adjustment device includes driving the embossing knob, such as pulling the illumination helmet in a clockwise direction and relaxing the illumination helmet in a counterclockwise direction. This tensioning can simultaneously adjust the depth of the headband and the lighting helmet. In another alternative embodiment, the strap is adjusted by a rack and pinion system. The adjustment device includes a tab that is equipped with a plurality of teeth forming a rack that is designed to mate with a pinion that is preferably secured to the occiput portion. The tabs are formed, for example, in the extension of the side portions and are inserted into the pinion of the occiput portion so that the portions forming the headwear of the illumination helmet move toward each other. The operation of the adjustment device includes sliding the teeth into the pinion gear to tension the lighting helmet, and pressing the two buttons of the pinion gear to release the tab and relax the lighting helmet.

In another alternative embodiment, the lighting helmet has a three-layer structure, i.e., a foam pad, a cap, and a casing portion. The cap completely covers the foam pad, and the slit of the foam pad is offset from the gap separating the portion of the outer casing. The cap represents a flexible connector that ensures articulation between the outer casing portions. Thus, the structure promotes sliding between the foam pad and the shell portion to provide optimum deformation of the lighting helmet. The small gap between the foam pad and the cap reflects the possibility of slippage between the foam pad and the shell portion.

In an alternative embodiment, the foam pad includes a thinned region in its wall thickness to promote deformation of the foam pad. The thinned region is preferably offset relative to the gap between the outer casing portions. This foam pad structure with a thinned area prevents the risk of sharp objects from penetrating the lighting helmet, thereby greatly improving the safety of the user.

In another alternative embodiment, the lighting head is provided with a multi-layered foam pad. The foam pad is formed from stacked plates for good compression absorption and flexural elasticity to ensure greater deformation of the entire foam pad and to ensure user comfort and safety. It is preferred that the panels made of foam have different properties in order to obtain a density of gradually varying foam mats to promote comfort and shock absorption. • For compartments covering the outer casing portion, the alternative embodiment is capable of selecting different fabrics, and for example the outer casing portion can have a rough end use condition. This approach has the advantage of using a fabric that may have elastic characteristics over the entire surface of the cap as compared to terminating or bonding.

In another alternative embodiment, the lighting helmet includes an outer fabric envelope that covers the outer casing portion. The outer envelope allows the lighting helmet to have a more aesthetic appearance. For example, the outer envelope can cover only a portion of the outer casing portion. For example, the crown portion can be exposed and the other portions can be covered with an outer envelope. This very advantageous structure allows the lighting helmet to envisage a variety of possible situations by varying the combination of material and color of the outer envelope and crown portion. Lighting helmets have many advantages. Because of the flexibility of the structure, There is a slidable and headgear adjustment between the layers that can cover multiple helmet sizes. The helmet is capable of covering a range of sizes with a limited standard. Furthermore, it is conceivable to maintain a certain outer casing portion between the two dimensional standards, and only to change the dimensions of the other outer casing portions. In this way, the number of tools needed to make a lighting helmet! !cut back. Because the thickness and volume of the foam pad are optimized, the weight of the lighting helmet is greatly reduced. The effective thickness of the foam material of the foam pad is optimized to fit the shape of the head. The dead volume typically required to reduce adjustment comfort will allow the foam pad to be placed very close to the head. The main effect is to reduce the leverage effect of the impact on the surface away from the head. The lighting helmet does not accelerate until it abuts against the cushioning stop formed by the user's head. Better distribution of impact surfaces for improved comfort and safety. Due to the relative mobility of the various outer casing portions, the illuminated helmet structure with the outer casing portion enables the lighting helmet to be properly adapted to the shape of the head by good adjustment. In particular, the occipital portion is pressed tightly against the user's head, resulting in better maintenance of the illuminated helmet and improved safety. The position and various shapes of the outer casing portion and the gap result in optimum deformation. In addition, the greater the number of outer casing parts, the higher the user's comfort.

In another embodiment, the lighting helmet is more aesthetically pleasing and has fewer projections because its overall appearance is more like a hat. The lighting helmet also enhances the user's field of view because it is closer to the head. When applied, it will be readily possible to provide the full range of lighting helmets depending on all possible combinations of material and color of the crown portion, other outer casing portions and the outer envelope covering the outer casing portion.

In another embodiment, the foam pad is divided into small pieces each connected to the cap. It is also possible to fill the compartments in the foam pad with foamed pellets. The foam pad thus formed has a large deformability due to its particle characteristics. The outer casing portion can be thermoformed from the plate in a single operation and then cut by water jet or by numerically controlled machining, 'and then fixed to the cap or belt. In order to facilitate the ventilation of the lighting helmet, in addition to the vent holes of the crown portion, different outer casing portions may be pierced with small holes, and the small holes may be covered with an open mesh fabric or a venting diaphragm. 'Ventilation can also be carried out on a cap or belt by selecting a very breathable fabric. It is also possible to use other shapes of the outer casing portion, cap or belt, the structure of the lighting helmet must be such that when the lighting helmet is worn on the user's head, it can be slightly slid between at least a portion of the outer casing portion and the foam pad to optimize his/her Comfort.

In another embodiment, the illuminating helmet of the present invention comprises an inner layer of interconnected layers of harder material, which are formed by a gasket and a thinner material segment having no shims. The layers are interconnected and further comprise an elliptical crown member. The segments of the inner layer extend longitudinally from the crown member and Abutting is maintained by the gasket along its longitudinal edges. The village mat also has the outer layer section located longitudinally adjacent to the inner layer section and the liner extending longitudinally from the crown member. Therefore, the longitudinal edges of the outer segment overlap on the longitudinal edges of any two adjacent inner segments. This solution creates a soft, resilient helmet with good consistency in the shape and size of the wearer's head and provides a very compact and flexible structure due to streamlined aerodynamic drag. Each of the inner layer members is formed in part by a relatively rigid section of hemispherical planar material, each of which is suitably shaped to accommodate its particular location. While having overall consistency, these segments can vary in thickness density depending on the degree of impact desired to withstand. They may be made of a variety of plastics, fiberglass, synthetic resins or metals or may be made from a combination of these materials, depending on a particular desired stiffness and impact resistance or other properties. Superimposed or glued onto the inner surface of each segment is a layer of energy absorbing material or gasket that is oriented in the finished assembly that will be adjacent to the interior of the helmet and the wearer's head. While the gasket has overall uniformity in this invention, the gasket can also vary in thickness or density depending on the degree of energy absorption required for a particular embodiment. Such a gasket may, for example, be a flattened polystyrene, a plurality of synthetic expanded foams, such as polyurethanes, polypropylene or polyethylene, a variety of synthetic or natural rubber compositions or other suitable materials having the desired characteristics in a particular embodiment. production.

In another embodiment, the liner may be made of a soft, elastic fabric or a liner made of a material similar to that of synthetic or natural rubber or a material containing these materials. The pads are fixedly attached to the inner layer of the member such that such a piece will conform to the longitudinal edges of the adjacent members. The sheets are secured to respective outer surfaces of the members that extend substantially the entire longitudinal direction thereof. The liner thus limits the inner layer member to the abutting structure described above, leaving the member with only a limited soft and resilient movement. The liner also fixedly mounts the inner layer members along the upper lateral edges of the members to the inner surface of the perimeter of the impact resistant section of the elliptical crown member on the helmet, so that the impact resistant section of the crown member extends over the overlapping structure The upper lateral edges of the inner layer members provide structural abutment resistance against impact at those locations. The shape and size of the inner layer members are such that they project from the longitudinal direction of the crown member in an arc-like radial manner to constitute the bottom edge of the helmet. They may also be sized and shaped to be mutually uniform (from their lateral direction), they may extend along the entire circumference of the crown member and laterally along the entire circumference of the helmet. This configuration of the inner layer members along the crown members thus constitutes an abutting inner helmet body. The outer layers of the same material as the segments constituting the inner layer members described above are shaped and sized to extend longitudinally from the closure of the periphery of the crown cavity to the bottom edge of the helmet. The shape and size may be such that they each extend laterally beyond the longitudinal abutting edges of adjacent inner layer members and overlap. The longitudinal center plane of each outer segment is adjacent to the adjacent inner layer The longitudinal abutment of the members, so that the structurally adjacent impact resistance can be raised at those locations. The liner mounts the outer layer segments along its central longitudinal face to the inner layer of the member so that it does not affect or limit the limited softness and elastic movement of the inner layer members.

In another embodiment, the outer layer segments are not laterally extended such that their longitudinal edges abut. Thus, the central longitudinal face of the inner layer member is exposed between adjacent overlapping outer layer segments such that the size of the region is determined by the particular helmet desired. The strap and can be attached to the outer segment by mechanical or other means prior to attachment of the conventional detachable hardware to its end to securely attach the helmet to the wearer's head. The position of the elliptical crown is such that its larger planar dimension is substantially aligned with the sagittal plane of the helmet (front-back). The lighting helmet assembly is such that a viscous compound is applied locally to the longitudinal end of each pad and applied to its respective portion on the inner layer member so that the abutting members can be fixedly mounted to each other. Together. The adhesive is applied to the upper lateral edge of the liner and the crown member is placed in its corresponding position and secured to the helmet. Then, an adhesive is applied to the central longitudinal faces of the pads, and the inner layer segments are then applied to their corresponding positions to securely mount them to the helmet. By providing a series of integral and fixedly mounted overlapping segments and members in a flexible, resilient assembly, the volume can be significantly minimized and the wearer's head shape and size can be maximized to avoid complete Problems with technical lighting helmets. Accordingly, one of ordinary skill in the art of helmet design and manufacture will appreciate that the present invention is fully achievable.

In another embodiment, the vent hole allows the outside air to flow in, and the internal heat is discharged to the outside of the helmet. At least two or more vent holes penetrating the inner and outer casings are provided at appropriate positions on the outer casing portion, on the inner side of the inner casing. The wall surface is provided with an air passage connecting the vent hole and a ventilating zone which will be described later. The air passage is a flow path of the outside air flowing through the vent hole in the form of a groove, and the scalp temperature of the user is lowered to achieve the effect of ventilation. A suitable portion of the peripheral wall of the outer casing portion is provided with a ventilating zone for forcibly discharging the heat and odor of the user's scalp, forcibly discharging the water to the outside of the helmet, and introducing the outside air. Further, in order to improve the decorative effect, the lighting helmet of the present invention is provided with a lamp for turning off and turning off the electric current generated by the dry battery driving, which not only improves the visual effect, but also makes it easy for the surrounding people to find their own position at night to prevent an accident. happened.
