[embodiment]

When changing in order to solve applied environment, identification light only has a sign, and it is difficult to tackle place environmental evolution problem, has proposed a kind of identification light of convertible sign.

See also Fig. 1, the identification light 100 of present embodiment comprises two rotating shafts 110, colored belt 120, backlight 130, two motor 140, driving circuit 150, fore shell 160, bonnet 170 and Transparent Parts 180.

Fore shell 160 is for having the cylindrical shell of the first openend 162.Bonnet 170 links to each other with the first openend 162 of fore shell 160, and bonnet 170 forms host cavity (figure is mark not) with fore shell 160, and the significant components such as colored belt 120 and backlight 130 are contained in the host cavity, and these significant components are shielded.

Two rotating shafts 110 are roughly elongated right cylinder, and an end is connected with two motor 140 respectively, and during work, motor 140 orders about rotating shaft 110 and rotates.

Be printed on a plurality of pattern (not shown) on the colored belt 120, pattern is comprised of the strong part of light transmission and light transmission weak part.Generally speaking, the part that light transmission is strong is literal, such as printed words such as " emergency exits ", is the light transmission weak part on every side.When pattern need to be showed, under the irradiation of backlight 130, light transmitted from word segment, and the light transmission weak part makes the strong word segment of light transmission more outstanding clear.In some cases, the part that light transmission is strong also can be the indicia patterns of some suggesting effects.

See also Fig. 2, colored belt 120 middle parts are displaying section 122, and two ends are connected with two rotating shafts 110 respectively, and coiling forms two spool sections 124 take rotating shaft 110 as axle.What occur in the displaying section 122 is the current pattern that will show, other pattern for subsequent use is hidden in the spool section 124 by coiling, when pattern for subsequent use need to be showed, the cooperation that drives respectively two rotating shafts 110 by two motor 140 is rotated, and the pattern that is hidden in spool section is moved to displaying section 122.

Backlight 130 is arranged on displaying section 122 1 sides of colored belt 120, the light that backlight 130 sends can cover whole displaying section 122, because the pattern of displaying section 122 is comprised of the strong part of light transmission and light transmission weak part, transmittance is different, the pattern that needs are showed can be shown by backlight 130.Specifically in the present embodiment, backlight 130 uses LED as light source, and LED is cold light source, small volume, and adaptive capacity to environment is strong simultaneously.In situation about satisfying the demands, backlight 130 also can adopt other light sources such as incandescent lamp.

Above-mentioned identification light 100, a plurality of patterns are set in colored belt 120, when needing to use one of them pattern, rotate by the cooperation of two rotating shafts 110, this pattern is moved to displaying section 122, and by backlight 130 irradiations required pattern is showed.When reply different application environment, this identification light 100 can be changed its pattern as required.

It is pointed out that two motor 140 also can save, rotate by hand two rotating shafts 110 by the people, the pattern that needs are showed moves to displaying section 122 places.At this moment, rotating shaft 110 needs sufficient length with outside the host cavity that extends to fore shell 160 and bonnet 170 formation, so that staff can touch and it be operated accordingly.

In order better to show the pattern at displaying section 122 places, fore shell 160 be square cylinder, and simultaneously, fore shell 160 comprises that also second openend 164, the second openends 164 corresponding with the first openend 162 offer light hole (figure marks).Transparent Parts 180 is made by light transmissive material, and the light hole size on size and the second openend 164 is complementary.Transparent Parts 180 is arranged at the second openend 164 places, and light hole is covered fully.

Because it is square that the displaying section 122 of colored belt 120 is generally, fore shell 160 is square cylinder, and displaying section 122 can better be displayed.Simultaneously at fore shell 160 light hole is set, and by Transparent Parts 180 light hole is covered, light can well be transmitted, and protected the important devices such as colored belt, backlight in the host cavity.It should be noted that fore shell 160 also can for cylinder etc. radially xsect be the cylindrical shell of other shape, satisfy the demand of unlike signal pattern.Transparent Parts can be convex lens, makes the pith in the pattern that needs to show, such as amplifications such as some tell-tale literal, better plays suggesting effect.

Driving circuit 150 is electrically connected with two motor 140 and backlight 130, is used to two motor 140 and backlight 130 that electric power is provided, and two motor 140 are controlled.See also Fig. 3, driving circuit 150 comprises control module 152 and driver module 154, and driver module 154 is connected with control module 152 communications.Control module 152 is for generation of control signal, and control signal is converted to after can inputing to control module 152 by outer signals, also can obtain from self storage unit.Driver module 154 is used to two motor 140 and backlight 130 that electric power is provided, and drives 140 rotations of two motor according to control signal.。Concrete, control module 152 comprises a plurality of shift knob (not shown), and respective identification is arranged on the shift knob.Staff is pressed corresponding shift knob, control module 152 produces corresponding control signal, driver module 154 just can be controlled two motor 140 according to control signal and do together the rotation that identifies direction with this shift knob, drive rotating shaft 110 needed pattern is moved to displaying section 122 from spool section 124, to replace the pattern in the former displaying section 122.

In order to strengthen the thermal diffusivity of identification light 100, see also Fig. 4, bonnet is provided with heat dissipation grid 172 on 170 middle parts.Backlight 130 is comprised of a plurality of strip-shaped light sources (figure is mark not).In the present embodiment, strip-shaped light source is formed a line by a plurality of LED lamps and forms.A plurality of strip-shaped light sources are fixed in the heat dissipation grid 172, and are separated by heat dissipation grid 172.

Be installed in the heat dissipation grid 172 by being separated by the backlight 130 that a plurality of strip-shaped light sources form, satisfied the demand of 100 pairs of heat radiations of identification light, increase its reliability in the different application environment.

The above embodiment has only expressed several embodiment of the present invention, and it describes comparatively concrete and detailed, but can not therefore be interpreted as the restriction to claim of the present invention.Should be pointed out that for the person of ordinary skill of the art without departing from the inventive concept of the premise, can also make some distortion and improvement, these all belong to protection scope of the present invention.Therefore, the protection domain of patent of the present invention should be as the criterion with claims.
