Abstract

The utility model relates to a fire-control emergency lighting lamp head comprising a lamp cover, a rear cover and a glistening cup arranged between the two. The lamp cover and the glistening cup are internally provided with a lamp house which is numbers of illuminant LBD fixed on a circuit plate at the outer side of the bottom of the glistening cup. The bottom of the glistening cup is opened with small holes corresponding to the number and position of the illuminant LED. The illuminant LED on the circuit plate is inserted inside the glistening cup from the corresponding small holes.

Description

The fire-fighting emergency headlamp lamp holder

Technical field

The utility model relates to a kind of fire-fighting emergency headlamp lamp holder.

Background technology

Existing fire-fighting emergency headlamp lamp holder comprises lampshade, bonnet and is fixed between the two reflector, cup end central authorities at reflector have a hole, lamp socket is housed in the hole, the outer end of lamp socket is fixed together by screw with the outside or the inboard at the cup end, bulb is positioned at lampshade and reflector, and bulb is contained in the hole of lamp socket.This fire-fighting emergency headlamp lamp holder is owing to adopt bulb as light source because the power consumption of bulb (incandescent lamp) is big, light efficiency low (generally be about every watt 10 lumen, the temperature height of bulb, life-span short (generally being in 1000 hours).And lamp envelope design is interchangeable, and bulb is tightened on the lamp socket, and long-time use is become flexible easily, come off, loose contact etc.

What send is sodium yellow, and illuminating effect is bad, and continuous lighting time is not long, and general continuous illumination is no more than 2 hours, and service life is not long yet.

Summary of the invention

The purpose of this utility model is the problems referred to above of existing at existing fire-fighting emergency headlamp lamp holder, provide a kind of energy-conservation, luminous efficiency is high, the life-span is long, do not need to change the fire-fighting emergency headlamp lamp holder of light source.

The purpose of this utility model is achieved in that the utility model comprises lampshade, bonnet and is located between the two reflector, in lampshade and reflector, be provided with light source, described light source is for counting to the dozens of light emitting diode, they are fixed on is fixed on the basolateral circuit board of reflector cup, have aperture with light emitting diode respective amount and position on the end at the cup of reflector, the light emitting diode on the circuit board is inserted in the reflector from the aperture of correspondence.

Technique effect of the present utility model is: the utility model has designed particular structure light emitting diode (LED) light source has been installed, owing to adopted light emitting diode as light source, the utility model long service life, life-span reached more than 50,000 hours, can use 10 years, power consumption is little, is 1/5th of bulb, light efficiency is 50 lumens up to every watt, good illumination effect.

The utility model is described in further detail below in conjunction with drawings and Examples.

Fig. 2 is the three-dimensional exploded view of embodiment.

Fig. 3 is the A-A profile of boss among Fig. 2.

The structure chart of circuit board among Fig. 4 embodiment.

The specific embodiment

As depicted in figs. 1 and 2, present embodiment comprises transparent lampshade 1, bonnet 3 and is located between the two reflector 2, the inboard of reflector 2 is towards lampshade 1, be provided with the fixed leg 101 of band screw in the inboard of lampshade 1, correspondence position is respectively equipped with through hole 203,301 on reflector 2 and bonnet 3, screw 4 is fixed on the fixed leg 101 from bonnet 3 outsides by through hole, thereby lampshade 1, reflector 2 and bonnet 3 are fixed together.

As shown in Figures 2 and 3, the boss 201 of projecting inward formation one circle of cup end mediad cup of reflector 2, the outside constitutes an alcove at the bottom of cup simultaneously, has 12 apertures 202 around boss 201 and line up a circle on glass end of reflector 2.As Fig. 2, Fig. 3 and shown in Figure 4, the outside at the bottom of 2 glasss of reflectors is provided with a circuit board 5, on circuit board 5, be fixed with 12 light emitting diodes 7, aperture 202 positions on they line up at the bottom of 2 glasss of a circle and the reflectors are corresponding, each light emitting diode 7 is inserted in the reflector 2 from its corresponding aperture 202, on circuit board 5, be provided with an aperture 8, screw passes this aperture 8 and is fixed on the screw column 204 in the alcove, thereby circuit board 5 is fixed on the outside of reflector 2, also be fixed with six current-limiting resistances 6 at the middle part of circuit board 2, they just in time are arranged in alcove after circuit board 5 fixes.Also can in the position corresponding it just in time be adorned within it if also be fixed with other electron component in the utility model on the circuit board with alcove.

12 light emitting diode 7 parallel connections in the present embodiment, the light emitting diode 7 of per two parallel connections is connected with a current-limiting resistance 6.

The quantity of the light emitting diode in the utility model be several to dozens of, the quantity and the position of the aperture at the bottom of the reflector cup are corresponding with light emitting diode.
