TECHNICAL FIELD
[0001] The present application belongs to the field of night warning protective clothing. BACKGROUND
[0002] Limitations of existing passive warning clothing: At present, the warning clothing widely used by night workers (such as highway repair, road cleaning, emergency rescue, etc.) mainly relies on reflective materials (such as reflective strips). This passive warning method relies on the irradiation of external light source to reflect light, and its warning effect is limited by environmental lighting conditions. In the case of insufficient light, poor light source angle or low visibility, the reflective warning effect will be significantly weakened or even disappeared, which poses a serious safety hazard.
[0003] Advantages and risks of active light-emitting warning clothing: In order to overcome the shortcomings of passive reflection, warning clothing with active light-emitting light source has emerged as the times require; this kind of clothing can continuously and actively emit high-brightness light signals, significantly improve the night visibility and warning effect, and does not depend on external light source.
[0004] However, such active light-emitting warning clothing has a key defect: its warning function completely depends on continuous power supply. Once a power failure occurs (such as battery depletion, line damage, accidental power failure, etc.), the LED lamp beads will immediately go out, and the warning effect will instantly disappear, exposing the workers to the dangerous environment instantly, and the risk may even be higher than that of the clothing equipped with only reflective strips. SUMMARY
[0005] Objectives of the application: In order to overcome the deficiencies in the prior art, the present application provides a safety warning protective clothing with LED light guide wire or patch light-emitting as light source, which can instantly continue the warning effect when the LED lamp beads suddenly fail due to any reason.
[0006] Technical solution: In order to achieve the above-mentioned purpose, the safety warning protective clothing with LED light guide wire or patch light-emitting as light source of the present application comprises a night work clothing body, and the surface of the night work clothing body has an active light-emitting belt.
[0007] The active light-emitting belt comprises two parallel sewn belts on the surface of the night work clothing body, a patch groove is formed between the two parallel sewn belts, and a plurality of patch type active light-emitting units are arranged in the length direction in the patch groove; each patch type active light-emitting unit is lower than the surface of the parallel sewn belt.

[0019] Beneficial effects: When attached, the peelable optical strip of this invention reflects and charges the photoluminescent disk; when the peelable optical strip is torn off, the photoluminescent disk is fully exposed; when the LED beads suddenly fail for any reason (such as power failure or circuit fault), the warning effect is immediately resumed.
[0020] Photoluminescent materials cleverly utilize the light energy of LEDs during operation for "real-time" charging, eliminating the need for additional charging equipment or operations. When used for the first time after being stored away from light (such as in a wardrobe), the LEDs automatically light up, completing the initial charging of the photoluminescent material and putting it into standby mode. This "charging when working, emitting light when failing" mechanism is highly self-consistent and intelligent. Attached Figure Description

[0026] The invention will now be further described with reference to the accompanying drawings.
[0027] As attached Figures 1 to 5 The example shown is a safety warning protective suit that uses LED light guides or patches as a light source, such as... Figure 1 and 2 The system includes a night work uniform body 1, the surface of which is provided with at least a passive reflective strip 51 and an active light-emitting strip 6. The active light-emitting strip 6 includes two parallel sewn strips 8 protruding from the surface of the night work uniform body 1, and a patch groove 9 is formed between the two parallel sewn strips 8. LED light guides or several patch-type active light-emitting units 50 are arranged along the length direction in the patch groove 9. The patch-type active light-emitting units 50 are fixedly bonded to the bottom of the patch groove 9 by silicone glue or UV glue. Each patch-type active light-emitting unit 50 is lower than the surface of the parallel sewn strips 8. The purpose of this arrangement is to ensure that each patch-type active light-emitting unit 50 does not protrude from the surface of the parallel sewn strips 8, effectively avoiding accidental scratches to each patch-type active light-emitting unit 50 during use.
[0028] Each patch-type active light-emitting unit 50 includes an LED bead 7. An LED power supply is provided on the night work suit body 1. The LED power supply is electrically connected to each LED bead 7 through a micro wire inside the night work suit body 1. Each LED bead 7 emits light when powered on.
[0029] like Figure 3 and 4 As shown, the patch-type active light-emitting unit 50 includes a photoluminescent disk 10, with LED beads 7 fixed at the geometric center of the photoluminescent disk 10; the photoluminescent disk 10 has the characteristic of absorbing light energy, storing it, and re-emitting photons; it also includes a peelable optical strip 5 adapted to the contour of the active light-emitting strip 6, which covers and is peelably adhered to the surface of the active light-emitting strip 6; the peelable optical strip 5 has several convex arc-shaped optical covers 3 arranged along its length direction, and each optical cover 3 corresponds to one patch-type active light-emitting unit 50 when the peelable optical strip 5 covers and is peelably adhered to the surface of the active light-emitting strip 6; a light guide lens 4 is integrally arranged coaxially at the axis of each optical cover 3. The LED beads 7 on each patch-type active light-emitting unit 50 are approximately coaxial with the light guide lens 4 on the corresponding optical cover 3; the inner wall of the optical cover 3 is a concave curved inner wall 11 with a light-reflective coating; with the peelable optical strip 5 covering and peelably adhering to the surface of the active light-emitting strip 6, the optical cover 3 covers the corresponding photoluminescent disk 10; when the LED beads 7 are powered on, part of the light that is radially propagated forward by the LED beads 7 continues to propagate forward through the light guide lens 4, and the other part is reflected backward and uniformly projected onto the surface of the photoluminescent disk 10 through the reflection of the concave curved inner wall 11 with the light-reflective coating; when the peelable optical strip 5 is peeled off from the active light-emitting strip 6, the photoluminescent disk 10 is fully exposed.
[0030] Working principle:
[0031] Under normal conditions, the peelable optical strip 5 stably covers and is peelably adhered to the surface of the active light-emitting strip 6; if the night worker takes the night work clothes body 1 out of the wardrobe at night, the photoluminescent disk 10 is in a non-charged state due to being idle in the dark, and the photoluminescent disk 10 will not emit light even in the dark.
[0032] After the staff put on the protective gear, they turn on the LED power supply. Each LED bead 7 is powered on, and part of the light from each LED bead 7 that is radially propagating forward is refracted by the light guide lens 4 and continues to propagate forward, thus playing an active warning role by passively emitting light without relying on light reflection. The other part of the light from the LED bead 7 that is radially propagating forward is reflected by the inner wall 11 of the concave curved surface of the light reflection coating of the optical cover 3 and is uniformly projected onto the surface of the photoluminescent disk 10. This allows the surface of the photoluminescent disk 10 to uniformly and stably receive photons, thereby achieving uniform and stable charging and putting the photoluminescent disk 10 into the charging state.
[0033] Under normal operation, when the user finds that the LED power is exhausted or the circuit is faulty, each LED bead 7 will turn off. At this time, the user should immediately tear the peelable optical strip 5 by hand so that the peelable optical strip 5 is separated from the active light-emitting strip 6. At this time, the photoluminescent disk 10 is fully exposed. At this time, each photoluminescent disk 10 in the charging state emits light outward and each photoluminescent disk 10 immediately provides a temporary active warning function.
[0034] Both the optical cover 3 and the light guide lens 4 are made of transparent acrylic material. The inner wall 11 of the concave curved surface of the light reflection coating is a metal coating. In a vacuum environment, gaseous metal particles are uniformly deposited on the surface of the acrylic sheet using a vacuum coating process to form a reflective film with a nanometer-thickness.
[0035] The LED beads 7 on each patch-type active light-emitting unit 50 are approximately coaxial with the light guide lens 4 on the corresponding optical cover 3, and the LED beads 7 do not coincide with the focal point of the light guide lens 4, so that the light transmitted through the light guide lens 4 is still divergent, thereby enhancing the warning range.
[0036] The inner wall 11 of the concave curved surface of the light-reflecting coating has a discrete perforation with several light-transmitting dots, which serves to transmit light.
[0037] The surface of the parallel sewing tape 8 is a hook side with a hook and loop structure, and the inner side 5a of the peelable optical tape 5 is a loop side with hook and loop; hook side: one side is covered with small, hard plastic hooks; loop side: the other side is covered with fine, soft nylon loops.
[0038] When the hook side and the nap side are pressed together, the hook will catch the loops, forming a secure connection. To separate them, simply apply a peeling force and tear; the hook will detach from the loops. This process can be repeated countless times.
[0039] Material selection for the photoluminescent disk 10 in this scheme:
[0040] Strontium dysprosium aluminate (SrAl2O4:Eu,Dy): A rare earth-doped aluminate material with a peak emission value of 520nm, which is close to the 555nm green region where the human eye is most sensitive, giving it extremely high visibility in dark environments. Experiments show that after exposure to 1000 lux illuminance for 15 minutes, its initial brightness can reach 15000 mcd / m², and after 30 minutes, it still maintains an effective warning brightness of over 2500 mcd / m².18 This material is chemically stable, weather-resistant, non-radioactive, and meets environmental protection requirements.
[0041] Zinc sulfide (ZnS:Cu): Although this copper-activated zinc sulfide material has a relatively short afterglow time of about 2-4 hours, it has rapid light absorption characteristics and can reach 80% of its saturation capacity in just 5 minutes of light exposure. Its yellow-green emission (530nm) also has good visual sensitivity.
[0042] Strontium dysprosium aluminate or zinc sulfide is mixed with transparent resin in a ratio of 1:3 to 1:5 and then hot-pressed to form a 1mm-3mm thick luminescent sheet. This composite technology retains the characteristics of the luminescent material while providing good flexibility and washability; a white synthetic fiber substrate layer can be added to the inside of the luminescent layer to enhance light emission efficiency through reflection.
[0043] The above are merely preferred embodiments of the present invention. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principle of the present invention, and these improvements and modifications should also be considered within the scope of protection of the present invention.
