Description
Technical field
The utility model relates to lighting technical field, particularly relates to a kind of portable illumination device that uses point source of light, specifically a kind of Optical devices that are used for mine lamp.
Background technology
Existing mine lamp adopts the mining incandescent lamp bulb of 4V, 0.7A, parabolic mirror, convex lens combining structure more.As light source, luminous efficiency is low with incandescent lamp bulb, and power consumption is big, and the temperature of filament can cause accident easily up to 2000～2500 ℃ when bulb used, and bulb service life is short, needs often to change.What have replaces incandescent lamp bulb with semiconductor light-emitting-diode (LED) as light source in said apparatus, but illuminating effect is not good.Also have with the mine lamp of led light source, adopt lens arrangement merely, only solved focus issues and astigmatic problem around having ignored, use very inconvenient.
The utility model content
The purpose of this utility model is in order to solve the problem that prior art exists, a kind of Optical devices that are used for mine lamp to be provided, reaching the irradiating angle better performances of center optically focused, astigmatism covering on every side, safety, reliable, the beneficial effect of saves energy.
The technical solution of the utility model is achieved in that on the basis of existing technology, adopt the single face convex lens, with semiconductor light-emitting-diode (LED) as light source, design is applicable to the material and the shape of the reflector of led light source and single face convex lens, and they are organically constituted Optical devices of the present utility model.Specifically, the utility model comprise lamp housing,, heat sink, lamp head ring, suspender belt, lamp ring gasket ring, special single face convex lens, main light source LED, secondary light source LED and the specially designed reflector of selecting; The lamp ring gasket ring is installed on the lamp housing, and main light source LED is installed in the center of heat sink, and secondary light source LED also is installed on the heat sink, is positioned at the next door of main light source LED, and heat sink is connected with an end of suspender belt, and is connected with the lamp ring gasket ring by the other end of suspender belt; The reflector bottom opening is enclosed within on the main light source LED, and the side perforate is enclosed within on the secondary light source LED, and the outer of reflector upper end is installed on the lamp ring gasket ring; The single face convex lens are installed on top at reflector, connect single face convex lens, reflector, lamp ring gasket ring and lamp housing and make this device constitute overall structure with lamp head ring.
Above-mentioned a kind of Optical devices that are used for mine lamp, said reflector is that a bottom is that plane, middle part are that the oral area that is similar to parabola, upper end is the peviform structure that extends outward the flat eaves of a circle, the center of bottom and a side at middle part respectively have a hole, be enclosed within respectively on main light source LED and the secondary light source LED, extend outward on top a circle on the flat eaves two breach and protruding down be to fold and constitute from flat eaves, be used for determining the position when reflector is installed on the lamp ring gasket ring.The material selection aluminum or the plastics of reflector are made.
The utility model advantage compared with prior art is:
1, because the utility model has adopted LED to make light source, maximum temperature is about 60 ℃, 2000～2500 ℃ temperature well below the incandescent lamp filament, needed electric current drops to 0.35A from 0.7A, so the degree of safety that causes gas explosion, causes the person to scald obviously improves, power consumption reduces greatly.
2, on probation through manufacturing experimently, compare with background technology, the optically focused of semiconductor light sources and astigmatic performance improve, and have improved intensity of illumination.Owing to adopted the novel large-power LED lamp, and designed the reflector supporting with it, illumination makes the dazzling sense of discomfort of people so solved closely.Reached center optically focused to realize illumination and long drive, astigmatism is with convenient purpose of observing ambient conditions.
