Description

The invention relates to the field of lighting lamp technology, which is intended for use as an individual portable lighting device in potentially explosive areas of premises and outdoor installations in accordance with GOST R 30852.13-2002 and other regulatory documents regulating the use of electrical equipment in explosive conditions (group II).

There is a known device for a portable lamp having a housing with an electric power source and a lighting lamp located therein, as well as a carrying handle made in the form of a frame, the upper end of which is attached to the lamp unit, and the lower end is mounted on the upper part of the current source housing. (Patent for a useful model of the Russian Federation No. 51413, 2005 IPC 21L 17/00. All structural units are assembled in a single metal case.

A significant disadvantage of such a scheme is that such lighting devices belong to a low safety category for sparking and failure due to external electrical influences.

The device of an individual portable lighting device for potentially explosive zones of premises and outdoor installations (group II) is proposed. In this design of the lantern, technical solutions are proposed that exclude the possibility of sparking in explosive areas, where, according to operating conditions, the formation of explosive mixtures of gases and vapors with air is possible.

EFFECT: flashlight is compact, lightweight and convenient for practical use for long-range illumination and signaling in all weather conditions and provides spark protection and reliable operation in extreme conditions, for example, in an explosive environment.

The technical result is achieved due to the fact that the explosion-proof lantern contains a housing, an illumination unit that includes an LED, a lens with a conical tube and a protective glass, as well as a battery and a control board. The body is made of two monolithic components made of impact-resistant plastic and consists of two panels connected to each other by means of a hollow bridge: a front cylindrical and a back flat rectangular, located at an angle of 30 ° to the axis of the cylindrical panel. A cylindrical stepped thin-walled glass is fixed on the front panel, inside of which there is a lighting unit assembled on a separate board, in which a protective glass is installed, made of durable synthetic material of macrolon and which has a complex shape with a separate cylindrical compartment for installation and fastening of an optical lens with a tube. A box is installed on a rectangular panel, inside of which are placed a control board filled with a compound and a lithium-ion battery, which are connected by electric wires with a reed switch, a LED and a charging adapter socket, while the reed switch and a charging socket are located in the niches of the cavity in such a way that The reed switch itself and the electrical contacts of the charging socket are fixed inside the cavity, and the magnetic actuator (magnet) of the reed switch installed on the movable button and the charging adapter socket are located in the niches outside the case, and the socket for the adapter itself is closed with a threaded plug. Places of installation of the glass on the front panel and protective glass in the glass have sealing gaskets.

The device of an explosion-proof lantern is illustrated by drawings.

FIG. 1 shows a section of the lantern;

FIG. 2 - general view of the lantern;

The body is made of impact-resistant plastic in the form of a front cylindrical panel 1, a rear rectangular panel 2 and a bridge 3 connecting them at an angle of 30 °, while a cylindrical plastic thin-walled glass 4 is fixed on the cylindrical panel 1, inside which the light block assembly is located: conical tube 5 with lens 6 and light-emitting diode 7, mounted on the electronic board 8. Cylindrical glass 4 is made stepped and fixed on the front panel 1 with a seal 9 and rolling of the edges of the glass 4, and the protective glass 10 installed in the glass 4 is made of durable synthetic material macrolon and has a complex structure with a separate cylindrical compartment 11 for installing and fixing an optical lens 6 with a tube 5, and glass 10 in a cylindrical glass is installed with a sealing gasket 12. The lighting unit with an LED 7 is assembled on a separate board 8, which is connected by wires to the control board 13. The control board 13 has an electronic Electrical connection with the socket 14 for connecting the charging adapter (in Fig. not shown), a switch 15 and a lithium-ion battery 16. The socket 14 for connecting the charging adapter, which is recessed in the niche and closed with a threaded plug 17 with the possibility of opening it only with a special technological key (not shown in the figure). The switch 15 is made in the form of a reed switch 18, located inside the cavity of the jumper 3 in a special niche, and its magnetic starter 19 (magnet) is fixed on the movable button 20 located outside. The control board 13 and the lithium-ion battery 16 are located in a rectangular plastic box 21 and are filled compound 22. Box 21 is fixed on the rear panel 2.

The device works as follows.

The explosion-proof lantern creates a directed stream of light from the LED 7 installed in the lighting unit, which includes the LED 7, the lens 6 with the conical tube 5 and the protective glass 10. The LED 7 is switched on / off using the button 20 of the reed switch mounted on the lamp body. Also on the case there is a socket 14 for connecting a charging adapter. The source of electrical energy of the lantern is a lithium-ion battery 16, which with a control board 13 is located in a rectangular plastic box 21, filled with a compound 22. Box 21 is fixed on the rear panel 2.

The main requirement for ensuring explosion safety during the operation of the flashlight is achieved through the following technical solutions used in its design:

- the body is made of monolithic shock-resistant plastic;

- a cylindrical stepped shape of a thin-walled plastic cup of increased rigidity is fixed on the front part of the body, inside of which there is a lighting unit assembled on a separate board;

- the body and a plastic cup with protective glass fixed on it are assembled with seals and a rolling of the cup edge, which ensures the tightness of the inner volume of the lantern;

- the protective glass installed in the glass is made of a durable synthetic material of makrolon and has a complex design with a separate cylindrical compartment for installing and fixing an optical lens and a tube;

- a reed switch was used, which, like the charging socket, are located in the niches of the jumper cavity in such a way that the reed device itself and the electrical contacts of the charging socket are fixed inside the cavity, and the magnetic actuator (magnet) of the reed switch installed on the movable button and the charging adapter socket are located in niches outside the body;

- socket for connecting the charging adapter, which is recessed into the niche and closed with a threaded plug.
