The moisture resistivity and shaking resistance capacities of the laneway lamp are remarkably improved; moreover, the LED square laneway lamp has the characteristics of compact structure, beautiful appearance, high efficiency and energy saving, as well as ultra-long service life; the LED square laneway lamp is broadly suitable for the coal mine underground working surfaces, laneways, underground chambers and movable devices with the dangerous gas mixtures which are inflammable and explosive.

Description

The square tunnel of a kind of LED lamp

Technical field

The utility model belongs to technical field of lighting fixtures, relates to the square tunnel of a kind of LED lamp.

Background technology

Existing tunnel explosion-proof lamp is limit owing to structure, the structure heaviness, use for a long time in the down-hole, moisture resistance anti-seismic performance is relatively poor, fault is more, and lighting hours is short, and therefore existing light fixture can not satisfy actual needs, especially have inflammable and explosive dangerous tunnel cave depot at mine and some, need the explosion-proof lamp of some overlength lighting hours especially.

Summary of the invention

The purpose of this utility model provides the square tunnel of a kind of LED lamp, and the moisture resistance anti-seismic performance that has solved the explosion-proof lamp existence of existing tunnel is relatively poor, causes the problem that fault is more, the lighting hours of light fixture can not be satisfied the demand.

The technical scheme that the utility model adopted is, the square tunnel of a kind of LED lamp, comprise square shell, the inside of shell is the square cavity of a single face opening, opening one end of this square cavity is equipped with lampshade, the sealing one end outer surface of this square cavity is provided with heat radiating fin, and the led light source assembly is installed in the cavity of shell; Side at shell is connected with a flame proof termination, be provided with in the cavity of flame proof termination and water envelope intrinsically safe power supply and flame proof binding post, the led light source assembly, water the envelope intrinsically safe power supply be connected by lead successively with the flame proof binding post, the flame proof binding post is connected with external cable by the cable entry that is arranged on the flame proof termination.

The feature of the utility model device also is,

The opposite side of shell is provided with battery backup, and battery backup is connected with emergent control panel.

The surface of shell is provided with the suspension ring of hanging usefulness.

The beneficial effects of the utility model are the obviously raising of moisture resistance shock resistance, compact conformation, good looking appearance, energy-efficient, extra long life.

The specific embodiment

Below in conjunction with the drawings and specific embodiments the utility model is elaborated.

Fig. 1 is the structural representation of the utility model tunnel lamp embodiment.Comprise the square shell 9 that aluminum alloy materials is made, the inside of shell 9 is square cavity of a single face opening, and opening one end of this square cavity is equipped with the lampshade 8 that poly-charcoal acid fat material is made, and lampshade 8 adopts exotic material, enlarged heat-dissipating space, reduced temperature rise and improved bulb life; The sealing one end outer surface of this square cavity is provided with heat radiating fin 6; Led light source assembly 7 is installed in the cavity of shell 9; Side at shell 9 is connected with a flame proof termination 2, flame proof termination 2 is provided with the end cover 1 that is used for the installation check internal unit, be provided with in the cavity of flame proof termination 2 and water envelope intrinsically safe power supply 4 and flame proof binding post 12, led light source assembly 7, water the envelope intrinsically safe power supply 4 be connected by lead successively with flame proof binding post 12, flame proof binding post 12 is connected with external cable by the cable entry 3 that is arranged on the flame proof termination 2; Opposite side at shell 9 also is provided with battery backup 10 and emergent control panel 11, and battery backup 10 is connected with led light source assembly 7, the control of meeting an urgent need of emergent 11 pairs of battery backup 10 of control panel.Have and can select the emergency light function of adding, reserve battery can make light fixture work under 9W power 100 minutes when alternating current cuts off the power supply.The surface of shell 9 is provided with the suspension ring 5 of hanging usefulness.

Each parts on the shell 9 all adopt and are tightly connected, shell 9 inner each parts also are to separate with the dividing plate sealing, adopt light fixture and power supply two chamber explosion separation structures, independent wire connection cavity is easy for installation, guaranteed moisture resistance antidetonation, meet up-to-date explosion-proof lamp requirement, can be in the safe and reliable work in inflammable and explosive hazardous area.

Fig. 2 is the operation principle block diagram of the utility model tunnel lamp.The flame proof binding post 12 of AC power 13 process flame proof terminations enters and waters envelope intrinsically safe power supply 4 (being explosion-proof driving power); water envelope intrinsically safe power supply 4 and form, drive the illumination of high-power LED light source group 7 luminous realization tunnels then by isolated form AC/DC constant-current source circuit 14 and dual over-voltage over-current protection circuit 15.

Tunnel of the present utility model lamp illumination (3 meters)〉30 lx, colour temperature is between 4500K～6000K, and rated voltage is AC (85～220) V, and type of explosion proof construc tion is Exmib I, and degree of protection can reach IP54.
