Below in conjunction with the accompanying drawing in embodiment of the present invention, the technical scheme in embodiment of the present invention is clearly and completely described.
The present invention relates to a kind of emergency exit indicating lamp 100, be installed on the top of the safety door of escape way, for perpendicular projection light beam to the ground of escape way, and the light beam projected has the function of safety guidance, such as, projective patterns is " outlet " printed words and arrow pattern, is used in reference to the person's of inducing one escape direction.
Refer to Fig. 1-Fig. 4, emergency exit indicating lamp 100 comprises light source 10, anti-dazzling screen 20 and projection lens 30, for described light source 10 issued light is reflected into the beam projection of pattern form to ground in the light path that described projection lens 30 is positioned at described light source 10, described projection lens 30 comprises incidence surface 32 and exiting surface 34, described incidence surface 32 is provided with light incidence section 322, the shape of described light incidence section 322 is identical with the shape of described pattern, in present embodiment, described pattern form is word shape or arrow-shaped.Described anti-dazzling screen 20 is provided with breach 22, and the shape of breach 22 is consistent with the shape of described pattern, and in present embodiment, described breach 22 shape is word shape or arrow-shaped.Described anti-dazzling screen 20 is located on the incidence surface 32 of described lens, and described light incidence section 322 is exposed through described breach 22, and anti-dazzling screen 20 is for blocking unwanted light.Described light source 10 is just to the center of described projecting lens 30, described exiting surface 34 is symmetrical centered by the optical axis A of described light source 10, described exiting surface 34 and in arc-shaped surface, the light beam reflected through described exiting surface 34 is symmetrical centered by described optical axis A.
Specifically, the light beam being projected to ground by projection lens 30 is positioned at immediately below emergency exit indicating lamp 100, in an emergency exit indicating lamp 100, arrange three groups there is the projection lens 30 of perpendicular projection function and corresponding light source 10, the shape of the light incidence section 322 of first projection lens 30 is the shape that Chinese character " goes out ", and the shape that the shape of the breach 22 of corresponding anti-dazzling screen 20 also " goes out " in Chinese character, like this, the light beam that this projection lens 30 is projected to ground is the shape that Chinese character " goes out ".The shape of the light incidence section 322 of second projection lens 30 is the shape of Chinese character " mouth ", and the shape of the shape of the breach 22 of corresponding anti-dazzling screen 20 also in Chinese character " mouth ", like this, the light beam that this projection lens 30 is projected to ground is the shape of Chinese character " mouth ".The shape of the light incidence section 322 of the 3rd projection lens 30 is arrowhead form, and the shape of the breach 22 of corresponding anti-dazzling screen 20 is also in arrowhead form, and like this, the light beam that this projection lens 30 is projected to ground is arrowhead form.Therefore, three groups of common projecting beams of projection lens 30 form pattern and the arrow pattern of " outlet " printed words, guide direction.
Emergency exit indicating lamp 100 provided by the invention can the light beam of projective patterns shape to ground, the personnel of guide press light beam indicated direction and escape.
Described emergency exit indicating lamp 100 also comprises collector lens 40, and light source 10 described in described collector lens 40 shade, the light for being sent by described light source 10 is focused to the incidence surface 32 of described projection lens 30.The light cover that light source 10 can send by collector lens 40 to the light incidence section 322 of projection lens 30, and makes uniform light distribute.
Described emergency exit indicating lamp 100 comprises circuit board 50 and battery 60, described light source 10 is fixed on circuit board 50, described battery 60 is electrically connected to described circuit board 50 for powering to described light source 10, described collector lens 40 is fixed to described circuit board 50, described collector lens 40 is provided with receiving space, and described light source 10 is contained in described receiving space.
Described emergency exit indicating lamp 100 also comprises reflector 70, and described reflector 70 is arranged between described collector lens 40 and described projection lens 30, for assembling the incidence surface 32 of the light emitted by described collector lens 40 to described projection lens 30.
Specifically, as shown in Figure 1, collector lens 40 comprises light collecting part 42 and installation portion 44, light collecting part 42 is substantially in pillow-like, for shade light source 10, installation portion 44 is for being fixedly connected with circuit board 50, and installation portion 44 is positioned at the relative both sides of light collecting part 42, pass installation portion 44 by screw and secure to circuit board 50, fixing with the installation realizing collector lens 40.
Reflector 70 comprise a pair fixing feet 72 and described to the light-reflecting portion 74 between fixing feet 72, fixing feet 72 is for being fixedly connected with circuit board 50, and light-reflecting portion 74 cup-shaped structure in hollow, the inner surface of light-reflecting portion 74 is reflective surface.The small end of light-reflecting portion 74 surrounds described collector lens 40, and the large end of light-reflecting portion 74 surrounds incidence surface 32, makes the light penetrated from collector lens 40 in light-reflecting portion 74 inside, via the reflection of reflective surface, concentrates on incidence surface 32.Add light source 10 go out the utilization rate of light.
The surface of described light incidence section 322 projects many row's excrescences 3222.Often arrange described excrescence 3222 all in semi-cylindrical.Described many row's excrescences 3222 are parallel to each other.Uniform intervals arrangement mutually between described many row's excrescences 3222, or, the end to end continuous arrangement of described many row's excrescences 3222.The design of excrescence 3222 improves the equal light effect of projection lens 30, and semi-cylindrical shape is more conducive to being uniformly distributed of light.
Described light incidence section 322 is in plane, and the plane orthogonal at place, described light incidence section 322 is in described optical axis A.
Refer to Fig. 4, the illumination that light source 10 sends is incident upon collector lens 40, the light cover that light source 10 sends by collector lens 40 is to the light incidence section 322 of projection lens 30, wherein, some light passes collector lens 40 direct irradiation to light incidence section 322, some light exposes to reflector 70 through collector lens 40, reflector 70 by light reflection to light incidence section 322, through the gathering of collector lens 40 pairs of light and the reflection of reflector 70 pairs of light, be radiated at the uniform light distribution of light incidence section 322, light passes projection lens 30 from light incidence section 322, penetrate from the exiting surface 34 of projection lens 30 and be projected to ground.Because anti-dazzling screen 20 has blocked the unwanted light of part, the scope that light is irradiated is in the scope of light incidence section 322, and light incidence section 322 is designed to pattern form, therefore, to penetrate and the light beam being projected to ground is pattern form from the exiting surface 34 of projection lens 30.
The above is the preferred embodiment of the present invention; it should be pointed out that for those skilled in the art, under the premise without departing from the principles of the invention; can also make some improvements and modifications, these improvements and modifications are also considered as protection scope of the present invention.
