An energy-saving highly effective LED and a high energy rechargeable maintenance-free battery, and an integral design with transparent material are adopted, the mining lamp is lighter, more reliable, and safer, hence an ideal lighting lamp for mine underground and night operation and construction.

Description

Light monoblock type mine lamp

Technical field

The utility model relates to down-hole, a kind of mine and night work lighting device, is that a kind of light source and power supply of comprising is the no cable connection structure of one, and the light all-in-one-piece mine lamp of continuous continuous illumination.

Background technology

At present the mine lamp that uses is connected and composed by cable by arbitrary source and power supply respectively, and power supply is worn and is hung between waist on the belt, and light source places on the skullcap on the crown.Its shortcoming is that security incident is drawn and caused to stube cable and fixture by the foreign matter extension easily at work, uses also inconvenience.

Summary of the invention

The purpose of this utility model provides a kind of light monoblock type mine lamp, is hung to draw by foreign matter at work by the cable ease of connection and causes security incident to overcome arbitrary source that prior art exists and power supply, and use inconvenient deficiency.In use more light, safe, reliable, can place the helmet or take off to hold according to the operation needs maybe need not place pocket in hand.

The technical solution of the utility model is: comprise light source and power supply, it is characterized in that: described light source adopts the light emitting diode light source module that has reverberation bowl; Described light source assembly and power supply are installed in the same housing, are provided with hatpin at the back side of this housing.

Described power supply is the non-maintaining chargeable storage group of high energy, and overcharge with one, overdischarge is connected with short-circuit protection circuit; On described housing, be provided with extrapolation charging inlet and sealing joint lid.

Described housing is tightly connected by main casing and bonnet and constitutes, and this main casing is made by transparent material, and the transmissive mirror of its front end and other parts are structure as a whole, and are provided with light non-transmittable layers on the surface of other parts except transmissive mirror; Described hatpin is located at the back side of covering bonnet; The reverberation bowl edge of described light source assembly is fixed on described transmissive mirror inboard with jump ring.

Between described main casing and the bonnet sealing gasket is housed, and pass the connecting hole that is located on the bonnet by screw fastening mutually with this main casing and bonnet, the outer end cap of this screw conceals in the counterbore of bonnet, and fills in this counterbore mouth with sealing-plug.

Be connected with change-over switch between described battery pack and light source, this change-over switch is installed in the groove at the bonnet back side, and seals with seal cover.

The utility model has the advantages that: its light source and power supply place in the monobloc container, and the structure that becomes one does not need outside the connection.Light source is the electronic component light emitting diode, the luminous efficiency height, and consumes power is little, and component life is long.The high energy maintenance-free battery volume that adopts is little, in light weight, non-maintaining.Housing is owing to the employing transparent material and through the black PROCESS FOR TREATMENT, and its transmissive mirror and its one do not need lamp head ring and locking device, thereby simplify the structure, and have improved reliability.It is the desirable lighting of down-hole, mine and night work construction.

The specific embodiment

Referring to Fig. 1～Fig. 5, the utility model embodiment comprises 1 (having reverberation bowl) of light emitting diode (LED) light source assembly and batteries 3, and light source assembly 1 is connected with batteries 3 by change-over switch 6.The electricity that overcharges, adopts a young relative, short circuit protection device (circuit board) 2 and light source assembly 1 are housed in the back of reflector 1.Described light source assembly 1, reflector 1, circuit board 2 and batteries 3 are installed in the same main casing 5, and seal with bonnet 8.Hatpin 12 is fixedlyed connected with screw 10 in the back side at lid bonnet 8 with spring washer 11.The charging inlet 9 of batteries 3 is located at bonnet 8 back sides, passes through screw 15 is connected a rubber access flap 17 with pressing plate 16 a end in the outside of charging inlet 9, the free end of access flap 17 can be raised when charging.

Change-over switch 6 is installed in the respective slot of bonnet 8, and seals with rubber closure 9.Change-over switch 6 adopts the self-recovering type electric push button.

Described batteries 3 is the non-maintaining chargeable storage group of high energy, adopts ferric phosphate lithium ion battery, and with overcharge, overdischarge is connected with short-circuit protection circuit (circuit board) 2.

Described main casing 5 is by transparent material (as PC) injection mo(u)lding, and transmissive mirror 51 and other parts 52 of its front end are structure as a whole single injection-molded.Through the black PROCESS FOR TREATMENT, make it light tight on the surface of other parts 52 except transmissive mirror 51, realize the purpose of its integration, saved traditional holder of miner's lampe circle and locking device thereof simultaneously.The reverberation bowl edge of described light source assembly 1 is fixed on described transmissive mirror 51 inboards with jump ring 13.

Between described main casing 5 and the bonnet 8 sealing gasket 7 is housed, and pass the connecting hole that is located on the bonnet by screw 14 fastening mutually with this main casing and bonnet 8, the outer end cap of this screw 14 conceals in the counterbore of bonnet, and with sealing-plug 20 this counterbore mouth is sealed (referring to Fig. 5).

Led light source assembly 1 can be buied in market, and its illuminator is the combination of a plurality of LED, forms two light sources by main light source 101 and secondary light source 102 among this embodiment.Make main light source 101 and secondary light source 102 alternately light (order is pressed change-over switch 6 in conversion between " main light source 101 is lighted, shutoff and secondary light source 102 light ") by change-over switch 6.

The luminous efficiency of led light source is apparently higher than traditional incandescent lamp (incandescent lamp 7.8lm/w; LED 30lm/w), utilizes this advantage, can reduce the capacity of mineral light significantly, the mine lamp volume and weight is reduced significantly.Overcharge, the application of overdischarge and short-circuit protection circuit 2 improved security reliability greatly.
