Technical Field

The utility model relates to the technical field of emergency rescue, in particular to a lifesaving lighting device.

Background

The lifesaving illumination line is a continuous illumination device aiming at guiding illumination and communication expansion equipment in a complex environment, and is mainly applied to the work of rescue, material transfer, personnel evacuation and the like in the environments of subways, tunnels, civil air defense projects, large passenger ships, cargo ships, underground nuclear power stations, high-rise buildings, large underground shopping malls, warehouses, caverns and the like. The main function of the lifesaving illumination line is to ensure the wireless signal coverage of the site and provide illumination indication with directivity under the severe environments, and prevent the rescue personnel and the fire fighting attack personnel from getting lost in the dark fire scene.

The lifesaving illumination line in the existing market adopts direct current power supply, is stable and durable in work, can be moved randomly, completely breaks away from the limitation of mains supply, and is convenient to carry.

However, the light-emitting wire generally adopts the EL cold light source light-emitting wire, which has insufficient brightness and unsatisfactory lighting effect, and the EL cold light source light-emitting wire needs to adopt high-voltage alternating current to drive light emission, so that the EL cold light source light-emitting wire does not meet the explosion-proof standard in some dangerous environments such as fire fields.

SUMMERY OF THE UTILITY MODEL

The embodiment of the utility model provides a lifesaving illumination device which can improve the use reliability of a lifesaving illumination line.

In order to achieve the above purpose, the embodiment of the utility model adopts the following technical scheme:

the power transmission part of the lifesaving illumination line adopts an enameled copper wire, LED light-emitting lamps 1 are arranged along the enameled copper wire at specified intervals, and the LED light-emitting lamps 1 form an illumination line connected with the enameled copper wire; n LED luminescent lamps 1 are connected in parallel to form a luminescent line L1, and m groups of luminescent lines L1 are connected in series to form a luminescent line L2, wherein n and m are positive integers; adopting a pouring sealant process on each LED luminescent lamp 1, and forming a pouring sealant 2 to cover the LED luminescent lamps 1; the outer layer 5 is wrapped outside all the LED luminescent lamps 1, and the outer surface of the outer layer 5 is covered with the reinforcing material 6 again.

In practical application, because the number of the LED luminescent lamps 1 is quite large, if all the LED lamps are connected in series, the required driving voltage is large, and meanwhile, as long as one LED lamp is damaged, the whole line does not emit light; if the two are connected in parallel, the required driving current is large, and the two modes do not meet the explosion-proof standard. In the embodiment, a mode of firstly connecting in parallel and then connecting in series is adopted, and other LED lamps are not influenced even if any LED in the circuit is damaged, so that the use reliability of the lifesaving illumination line is improved.

An embodiment of the present invention provides a lifesaving illumination device, as shown in fig. 1 to 6, including: the power transmission part of the lifesaving illumination line adopts an enameled copper wire, LED light-emitting lamps 1 are arranged along the enameled copper wire at specified intervals, and the LED light-emitting lamps 1 form an illumination line connected with the enameled copper wire; the n LED light emitting lamps 1 are connected in parallel to form a light emitting line L1, and the m groups of light emitting lines L1 are connected in series to form a light emitting line L2.

Wherein n and m are positive integers, and specifically, the parameter n is changed according to the change of the cross section area of the selected enameled copper wire. Further, as shown in figure 4, a layer of PVC or other transparent plastics material is injection moulded to the outer layer 5 to improve stability.

And (3) adopting a pouring sealant process on each LED luminescent lamp 1, and forming a pouring sealant 2 to cover the LED luminescent lamps 1. As shown in fig. 3, a potting process is applied to each LED, and the potting adhesive 2 may be an epoxy resin adhesive or the like to protect the electronic device and improve the performance of the electronic device.

The outer layer 5 is wrapped outside all the LED luminescent lamps 1, and the outer surface of the outer layer 5 is covered with the reinforcing material 6 again.

Specifically, the positive and negative electrodes of the lifesaving illumination line are connected with the positive and negative electrodes of the power supply on the main control panel, and a control switch 8 is connected in series between the positive electrode of the lifesaving illumination line and the stability material 7. For example: as shown in fig. 6, the positive and negative electrodes of the illumination line are connected to the positive and negative electrodes of the power supply on the main control panel, and a plurality of control switches 8 are connected in series between the positive electrode and the nylon wire or steel wire for controlling the constant, flicker, etc. of the illumination line.

Further, a metal sleeve 9 is arranged at each end of the lifesaving illumination line, and the stability material 7 penetrates through the opening 10 and is fixed on the opening 10. For example: in order to increase the tensile and compressive strength of the life saving illumination line, a metal sleeve 9 (such as a copper sleeve or an aluminum sleeve) is pressed on each end of the life saving illumination line, and then the stability material 7 (nylon wire, steel wire, etc.) is passed through the opening 10 and fixed on the opening 10, as shown in fig. 11-12.

In a preferred embodiment of the present invention, the cross-sectional area of the enameled copper wire is 0.13mm2, and the resistance value is 0.143 Ω/m. Specifically, the copper wire in this embodiment is a 26 # enameled copper wire, the cross-sectional area is about 0.13mm2, and the resistance value is 0.143 Ω/m, and the reason why this specification of enameled copper wire is selected is: the copper wire with the cross section is convenient to produce, is not too heavy if the luminous wire is long, and is too thin and easy to break if the copper wire is too thick to facilitate injection molding, so that the enameled copper wire with the cross section of 0.13mm2 is suitable to be selected.

In a preferred embodiment of the present invention, the distance between adjacent LED light-emitting lamps 1 is 10 cm. The distance between the adjacent LED luminescent lamps 1 is properly selected to be 10cm, if the distance is too short, the number of the LED lamps needed by luminescent lines with the same length is large, the material and manufacturing cost is increased, and if the distance is too long, the luminescent effect is poor. Therefore, the distance between the adjacent LED light-emitting lamps 1 is selected to be 10cm on the premise of ensuring the continuity of the light string and considering the cost, and the resistance value of the enameled copper wire between the adjacent LEDs is 0.0143 Ω × 2 — 0.0286 Ω. According to the intrinsic safety explosion-proof standard, the maximum current allowed by IIB type equipment is not more than 201mA under the voltage of 30V-33V, therefore, the current standard is set to be less than 150mA in the embodiment, under the current, according to the resistance value of an enameled wire, the distribution condition of LEDs, through current calculation and physical measurement, under the condition that the length of a light-emitting wire is controlled to be not more than 10m (100 LEDs are connected in parallel), the current difference between the LEDs at two ends and the middle LED is not more than 12%, the brightness difference is not more than 10%, and the brightness difference is basically difficult to find on the visual distance. In this embodiment, x in fig. 1 is 10cm and n is 100 according to the cross-sectional area of the enameled wire and the current standard, that is, 100 LED luminescent lamps 1 are connected in parallel at a distance of 10cm, and the length of the luminescent line after parallel connection is 10cm × 100 — 10m, that is, the luminescent line L1.

Specifically, under the voltage of 30V-33V, the volt-ampere characteristics of the LED are considered, that is, 10 groups of light emitting lines L1 are connected in series at most to ensure the light emitting brightness of the LED, so as to form a light emitting line L2 with a length of 100 m. If explosion-proof is not considered, the driving voltage at the two ends of the positive electrode and the negative electrode can be increased, and more than 10 groups of L2 can be connected in series

In particular, a stabilizing material 7 is also arranged between the outer layer 5 and the reinforcing material 6, the stabilizing material 7 being processed into one or more filamentary structures, including nylon filaments or steel filaments. For example: in fig. 5, in order to increase the tensile strength and compressive strength of the luminescent wire, the final luminescent wire is formed by adding the stability material 7, and the reinforcing material 6 is made of injection molding material.

Further alternatively, besides implementing constant or flashing, a pipeline display mode is also designed, and the connection mode of fig. 7-9 can be adopted. Wherein, n LED luminescent lamps 1 are sequentially connected in a circulating reverse order to form a luminescent line L1'; the m/2 groups of luminous lines L1 'are connected in series to form a luminous line L2'. For example: as shown in FIG. 7, n LED lamps are connected in reverse order to constitute a light emitting line L1 ', the interval between adjacent LED lamps is 2x cm, if x and n are calculated as 10cm and 100 in example 1, the interval between adjacent LED lamps is 20cm, and the length of L1' is 20 m. As shown in fig. 8, m/2 groups of light emitting lines L1 ' are connected in series to form light emitting lines L2 ', and as shown in fig. 9, two groups of L2 ' are arranged offset by x meters, with group 1 above and group 2 below, so that all LEDs are on a plane, so that the spacing between all adjacent LEDs is still x meters visually, where m/2 groups of light emitting lines L1 ' are connected in series to form light emitting lines L2 ' in order to maintain the same length as L2 in example 1.

The specific operation mode is as shown in fig. 10, after the light emitting line is connected with the main control board, the water flowing function is started by pressing the control switch 8, as shown in fig. 9, the main control board controls 3 to be at a high level, and controls 3 'and 4 to be at a low level, then all the LED lamps a in L2' (group 1) are lighted; then, the main control board rapidly controls the 3 and 4 to be in a low level, and the 3 'is in a high level, so that all the LED lamps B in the L2' (group 2) are lightened; the main control board rapidly controls 3 to be low level and 4 and 3 'to be high level, then all the LED lamps C in L2' (group 1) are lighted; the main control board then rapidly controls 3 and 4 to be high level and 3 'to be low level, then all the LED lamps D in L2' (group 1) are lighted. The main control board controls the change of the 3, 3' and 4 levels, all A, B, C, DLED lamps are circularly lighted, and the running water display is realized; if the main control board controls the rate of change of the 3, 3' and 4 levels to be fast enough, then the A, B, C, D light is visually indistinguishable and the A, B, C, D is visually perceived to be simultaneously on, and a constant effect can be achieved. The software can also realize that the AB lamp is simultaneously lightened, then the CD lamp is simultaneously lightened in the flowing water mode, the ABC lamp is simultaneously lightened, and then the D lamp is lightened in the flowing water mode or other display modes.

Further, as shown in fig. 13, a signal transmission line is further integrated in the lifesaving illumination line, and the signal transmission line is used for transmitting communication signals and realizing functions such as communication.

The embodiments in the present specification are described in a progressive manner, and the same and similar parts among the embodiments are referred to each other, and each embodiment focuses on the differences from the other embodiments.
