Abstract

The utility model relates to a novel color changing lamp, which uses white light as a light source and uses colorless transparent glass or organic glass as a bracket layer and a protective layer. Polarizing sheets, anisotropic crystal slices and light sloping sheets are orderly fixed in front of the white light source, and the light sloping sheets rotate following the bracket layer. According to the theory of anisotropic through transmission rotary color dispersion, the utility model generates beautiful and soft color light which is changed continuously and the color light can be adjusted to light in any fixed color by hands according to need.

Description

Colour-changing lamp

The utility model is a kind of Colour-changing lamp, is particularly suitable for making various technologies, decorative lamp, wall lamp, pendent lamp, stage, film studio illuminating lamp and the various advertising signboard lamp used as family, dance hall.

The existing lamp that can send colour lamplight has neon light, colored bulb lamp etc.The generation of these colour lamplights all is the principle of absorption according to optics, principle of interference, and three primary colors composition principle and fluorescence principle etc. is made.They all can only produce changeless coloured light.

Task of the present utility model is to overcome existing light fixture can only produce the fixedly deficiency of coloured light, design the continuous conversion light color of a kind of energy, and color is soft, controls Colour-changing lamp easily.

The utility model is to be light source with the white light; do shelf layer and protective layer with colourless transparent glass or lucite; Colour-changing lamp by low speed fractional motor or the rotation of clockwork spring driving arm layer; there is a fixing polarizer in the place ahead that it is characterized in that white light source; before the polarizer is one deck heterogeneous body crystal microchip, is the polarizer that one deck rotates together with shelf layer before the heterogeneous body crystal microchip.

The utility model is that the heterogeneous body transmission rotatory dispersion principle according to light develops.After white light is through the Colour-changing lamp device, promptly become the colourama of continuous variation.When not switching on, the luminous part of Colour-changing lamp is water white.During energising, white light passes through fixedly polarizer, becomes the linear polarization that has only a direction of vibration.Linear polarization promptly produces many monochromatic elliptical polarized lights and linear polarization penetrating heterogeneous body crystal (natural or artificial lens is as mica, quartz, feldspar, calcite or organic crystal etc.) thin slice.After elliptical polarized light and linear polarization see through the rotatory polarization sheet, because the plane of polarisation direction of rotatory polarization sheet ceaselessly changes, the amplitude size that each monochromatic light sees through the rotatory polarization sheet relatively constantly changes, so by synthesizing of light just producing the continually varying color of light.When the rotatory polarization sheet does not rotate, be a kind of color, can change, make Colour-changing lamp demonstrate needed certain color by the polarization direction of manual adjusting knob with the rotatory polarization sheet through the light behind this polarizer.When the rotatory polarization sheet rotates, the light color difference that its each orientation is synthetic, therefore, rotate a circle and various synthetic colouramas just occurred, and it is, therefore seem that the color of light is soft, and much brighter than what obtain with other principles because the purity of every kind of colourama is little.

Fixedly polarizer in the utility model Colour-changing lamp and heterogeneous body crystal microchip can be bonded at respectively on a slice colourless transparent glass support with homogeneous water white transparency viscose binder, also can be with white light source and fixedly polarizer, heterogeneous body crystal microchip are fixed on the rotatable base, drive by motor or clockwork spring, with respect to aforesaid rotatory polarization sheet (do not rotate this moment) rotation, also can produce identical chatoyance effect.

If will make the light of Colour-changing lamp gather into a branch of parallel or light of dispersing slightly, also will and fixedly add a collector lens between the polarizer at white light source.When if the temperature of white light source is higher, also should or on the glass bulb of white light source bulb, apply the hot coating of a metafiltration at heating filter disc between white light source and the collector lens.

The utility model embodiment is as follows:

Accompanying drawing 1 is chatoyance stage illumination, lighting lamp A-A cutaway view.

Accompanying drawing 2 is chatoyance stage illumination, lighting lamp front view.

As the incandescent lamp (1) of white light source, be installed on the lamp socket (2), lamp socket is fixed in again on the metal shell (3).There is a hot filter disc (4) in the place ahead of incandescent lamp, is a collector lens (5) before the hot filter disc, and white light source is positioned near the focus of collector lens.Being one deck before the collector lens is bonded at fixedly polarizer (6) on the colourless transparent glass with homogeneous water white transparency viscose binder, fixedly being one deck before the polarizer is bonded at heterogeneous body crystal microchip (7) on the colourless transparent glass with homogeneous water white transparency viscose binder, and after this being one deck is bonded at rotatory polarization sheet (8) on the colourless transparent glass with homogeneous water white transparency viscose binder.This glass of having pasted polarizer is driven by a low speed fractional motor (9), between the rotating shaft of fractional motor and the rotatory polarization sheet by belt (10) transmission.Outermost layer is cover glass (11), and the bulb power switch (12) of Colour-changing lamp is installed on the base of chatoyance stage illumination, lighting lamp.The luffing angle of Colour-changing lamp is by fixedly spiral (14) adjustment, and chatoyance speed can be by rotating speed selection key (15) control, and the rotating speed selection key links to each other with low speed fractional motor power supply.If want chatoyance stage illumination, lighting lamp to keep certain color, the motor power that can break is regulated manual adjusting knob (16), adjusts needed color.The metal shell of chatoyance stage illumination, lighting lamp has also been opened some louvres (13), and the heat that incandescent lamp is sent dissipates as quickly as possible.

The white light that incandescent lamp sends is lowered the temperature after heat-reducing filter absorbs infrared ray earlier, sees through collector lens then, becomes a branch of light of dispersing slightly.This light transmission fixedly becomes the linear polarization that has only a direction of vibration behind the polarizer, see through the heterogeneous body crystal again, produce many monochromatic elliptical polarized lights and linear polarization, and then by synthesizing of rotatory polarization sheet just producing continually varying, beautiful subdued colour light.
