Employing the invention has the beneficial effects as follows, it is not overlapping that described reflective mirror reflects the light of the light of described light source and described light source, direct irradiation is on light source both sides and ground, vertically the luminous intensity distribution distance is longer, improved the utilization rate of light, reduced the light source usage quantity of certain distance, the light of simultaneously described reflective mirror reflection is not by described light source, reduce the temperature of described light source, prolonged the service life of described light source.
Description of drawings
The invention will be further described below in conjunction with drawings and Examples, in the accompanying drawing:
Fig. 1 is the schematic diagram of tunnel of the present invention lamp;
Fig. 2 is the cutaway view of Fig. 1;
Fig. 3 is the cutaway view of A-A direction among Fig. 2.
The specific embodiment
Tunnel of the present invention lamp as shown in Figure 1 to Figure 3, comprise upper casing 10, lower casing 11 and Transparent Parts 15, and at the reflective mirror 13 and the electric appliance component 14 of the light of the light source 12 of described upper casing 10, lower casing 11 and Transparent Parts 15 formed cavity insides, the described light source 12 of reflection.
Described reflective mirror 13 is formed by being symmetrically distributed in two curved reflecting surfaces that are located at described light source 12 axis top, and described two reflectings surface can also be the planes.Described two reflectings surface are opposing and be formed slopely V-shape.Described light source 12 is the Metal halogen lamp light source, also can adopt other linear lightings.Described light source 12 horizontal positioned, and the symmetry axis of 13 two curved reflecting surfaces of the axis of light source 12 and described reflective mirror is parallel.Because the light that light source 12 is sent is perpendicular to the axis direction of described light source 12, when adopting such set-up mode, use light that described light source 12 sent light, the axis direction of main edge perpendicular to described light source 12 distributed through the two reflectings surface reflection of described reflective mirror 13.
When the tunnel lamp is installed, the axis direction of light source 12 is arranged to move towards vertical with the tunnel, then the light of reflective mirror 12 reflections will mainly distribute along the tunnel, can reach 10 apart from height ratio.Described lower casing 11 is provided with two supports 16 respectively near the position of described reflective mirror 13 vertical both sides, described reflective mirror 13 vertical both sides are connected with described two gripper shoes 16 by riveted way respectively, thereby be fixed in the described lower casing 11, described reflective mirror 13 can also be fixed in the described housing by other known manner, can adjust the position of described luminous mirror 13 by adjusting described two gripper shoes 16, to control the luminous intensity distribution distance of described luminous mirror 13 reflection rays along the tunnel.
Described lower casing 11 comprises the frame of top and perpendicular to the plate of described light source 12 axis both sides.Described frame and 10 combinations of described upper casing, the biside plate of described lower casing 11 will further reduce the luminous intensity distribution of both sides, 12 pairs of tunnels of described light source as being set to opaque.
The light of the tunnel lamp of said structure concentrates main across pitch to distribute, in use, can reduce ray cast significantly on the metope in tunnel, about 80% light can shine cover on the ground in tunnel, and the light of single source obtains utilizing effectively fully, increases the distance of single tunnel light source luminous intensity distribution simultaneously, can reduce the quantity that light source uses in the tunnel, not only saved the quantity of light fixture, and guaranteed to have reduced demand under the prerequisite that illumination needs electric energy.
Tunnel lamp in the present embodiment, the top of described reflective mirror 13 is provided with described electric appliance component 14, comprise assemblies such as ballast, described reflective mirror 13 is when playing reflection action, also played heat insulation effect, described speculum 13 has reduced the influence of the heat of 12 radiation of light source to described electric appliance component 14, has prolonged the service life of described electric appliance component 14, has improved the utilization rate of light fixture.
The tunnel lamp of present embodiment, wherein said Transparent Parts 15 comprise along the two dull and stereotyped Transparent Parts setting of 13 two reflecting surface symmetry axis of described reflective mirror, that be formed slopely angle and forming.And existing light fixture is when implementing the light fixture of complicated requirement, the general less special-shaped Transparent Parts of impact strength that adopts, but the mining tunnel lamp has certain requirement to the impact strength of housing and Transparent Parts 15 usually, use the tunnel lamp of special-shaped Transparent Parts need add guard in addition reaching mining requirement, or improve processing cost and make the satisfactory special-shaped Transparent Parts of impact strength.In the present embodiment, because Transparent Parts 15 has adopted leg-of-mutton topology layout, makes used planar transparent part material therefor not need other processing, so reduced manufacturing cost, simultaneously can satisfy the shock proof requirement of strength of mining tunnel lamp fully, improve the safety coefficient of light fixture.
The tunnel lamp of present embodiment, be equipped with metal gasket 17 at the edge of described dull and stereotyped Transparent Parts, the upper side frame of described lower casing 11 and biside plate and dull and stereotyped Transparent Parts junction are provided with clamping piece 18, by clamping piece 18 described dull and stereotyped Transparent Parts is fixed on the described lower casing 11, also be provided with cushion pad 19 between described clamping piece 18 and the described dull and stereotyped Transparent Parts, cause destruction dull and stereotyped Transparent Parts to make dull and stereotyped Transparent Parts generation stress after reducing clamping piece 18 and the rigidity of described dull and stereotyped Transparent Parts contacting.The junction of the upper side frame of described dull and stereotyped Transparent Parts and described lower casing 11, the junction of biside plate and described two dull and stereotyped Transparent Parts all seals with silica gel 20, the glue of silica gel can be when dull and stereotyped Transparent Parts be expanded with heat and contract with cold, play the effect of expanding with heat and contract with cold with dull and stereotyped Transparent Parts, avoid producing stress and cause destruction Transparent Parts in this process middle plateform Transparent Parts, and because silica gel 20 is positioned at the below of light source 12, so the luminous intensity distribution to the light fixture both sides does not impact, the needs of the remote illumination in tunnel have been guaranteed.Simultaneously, this light fixture integral body reaches requirement of explosion, and present embodiment also can be used as anti-explosion roadway lamp for mine and uses.
