Description
Technical field
The utility model lighting technical field, particularly the miner is with the technical field of portable, the emergency lighting under the mine.
Background technology
The tradition mine lamp is made up of lamp holder, battery and cable, the employing of its lamp holder be that traditional bulb is as luminescent device.Bulb is luminous by turning white-hot after the filament energising, is thermal light source, exists frangible danger, also needs the add-on security protector, and power consumption is big, crosses high shortcoming with temperature long afterwards.Because the voltage and the energy consumption requirement of bulb, the battery volume of adapted is bigger, and weight is also bigger, and used electrolyte has extremely strong corrosivity.Lamp holder and battery are two separation members, between link to each other with cable, cable is easily hung with other thing and is pulled, and brings much unnecessary burden and potential safety hazards to underground work.
The utility model content:
The purpose of this utility model is to provide a kind of light energy-saving mine lamp, overcomes the deficiency that bulb heating, power consumption separate with battery with lamp holder greatly, and lamp holder and battery combination are in the same place, constitute incorporate safe, lightly, mine lamp easily
For achieving the above object, the technical solution of the utility model is: a kind of light energy-saving mine lamp comprises lamp holder, switch, battery, clamp, flame proof housing, charging terminal, constant current match circuit; Described lamp holder is at the front end of flame proof housing; The middle part of described battery in the flame proof housing; Clamp is connected the back outer end of flame proof housing; Described charging terminal is below battery, and an end is connected in the flame proof housing on the constant current match circuit, and the other end exposes the flame proof housing, and described switch is below lamp holder; Described constant current match circuit connects lamp holder, switch, battery, charging terminal in the flame proof housing; The cross section of described dust cover is identical with the shape of cross section of lamp holder, is enclosed within the leading flank of lamp shell, has a circle to be parallel to the projection of its cross section in the dust cover, and the lower edge is longer than in the dust cover upper edge.
Described constant current match circuit forms the bistable switch latching circuit by two NAND gate series connection; Play coupling by a 10K resistance; Form constant current output circuit by transistor circuit; Utilize the one-way of commutation diode to form oppositely ending of charging circuit;
Described lamp holder is solid-state cold light source;
Described lamp holder is the white semiconductor light emitting diode;
Described battery is a solid state rechargeable batteries;
Described switch is that fluorescent material is made;
Described clamp is the u type, and Open Side Down, and an end is fixed on the back outer end of flame proof housing.
On the lateral film of described clamp lockhole is arranged.
The operation principle of the light energy-saving mine lamp that the utility model provides: several white semiconductor light emitting diodes are integrated on the circuit board, place the lamp holder position of mine lamp, replace incandescent lamp bulb as luminescent device, but guarantee that its illumination does not descend, because the white semiconductor light emitting diode is solid-state cold light source, energy consumption is little, and is safe and reliable; What power supply was adopted is solid state rechargeable batteries, and reusable, its volume is minimum, links together with the white semiconductor LED light lamp, light and handy convenient; The constant current match circuit is an intrinsic safety type, and constant current output under the situation of voltage change guarantees the work of white semiconductor light emitting diode, lengthens working hours, and it is no current when function guarantees the charging terminal short circuit oppositely; The shell flame proof closely links together each several part, is connected on the miners' cap by clamp; Switch is difficult for accident power-off between lamp holder and miners' cap; Dust cover upper edge dust-break, water etc., be not in the light in the lower edge.
From above-mentioned operation principle as can be seen, the light energy-saving mine lamp that the utility model provides is lightly convenient, safe and reliable, and to not influence of illumination, the working time is long.
