Description
Technical field
The present invention relates to a kind of method and device that changes shot-light scattering or transmissive state.
Prior art
Present shot-light is with the focus place of a light source arrangement at an optical reflector of curved surface mostly, makes light that light source sends after reflection, becomes ray light.As flashlight commonly used in the family, just can only shine at a distance, and have only a hot spot.Chinese patent literature CN1181284C discloses a kind of " one-way full light projection lamp " for another example, and this shot-light is that the light that light source sends is reflected the light beam that the coordinate X-direction does not have other scattered beam by force that is parallel to of back formation by convex lens, spherical reflector, parabolic reflector refraction.Adjust the diopter that convex lens move to left or reduce convex lens, parabolic reflector moves to right or expands the parabolic reflector opening, makes light beam form the covering of the fan illumination beam after transferring to the relevant position.Before lamp, add convex lens and can change original light beam into the covering of the fan outgoing beam.This invention can reach higher cover also can transfer to covering of the fan irradiation purpose.
And for example Chinese patent literature CN2093302 discloses a kind of vehicle low shot-light that meets at night.It is that the geometrical curve face that curve rotation 120 degree that reflective surface adopts 180 degree circular arcs to link to each other with 1/2 parabola form is made.The center of circle of circular arc and parabolic focus are on the same point, the light source of low shot-light is installed on the point at the center of circle and focus place, the light that this low shot-light penetrates, the road surface that illumination levels is following does not stimulate the other side driver that is higher than car light and pedestrian's eyes, has thoroughly solved meeting driver and pedestrian and has been subjected to light to stimulate accident-prone problem, during meeting, the driver needn't turn off the light, also can safe meeting, and be a kind of light fixture that is better than other dipped headlights scheme.
No matter the shot-light of above-mentioned which kind of form all can only shine at a distance, and it is powerless to form scattering on hand.In addition, this shot-light has only the effect of illumination, its function singleness.
Technical scheme
The technical problem that the present invention solves is to overcome above-mentioned shortcoming, provides a kind of under the situation that does not change the light fixture any structure, just can change the scattering of shot-light or the method for transmissive state, and the device of realizing its method.
But but this device not only direct projection but also scattering.
In addition, this device also can provide different patterns or/and Word message according to user's needs except that can be used for illumination.
Technical scheme of the present invention is: a kind of method that changes shot-light scattering or transmissive state, it is to set up liquid crystal light valve and correspondent control circuits thereof to illuminating source, make by regulating the voltage of this liquid crystal light valve, and scattering or the transmissive state and the degree of change light source, to reach the purpose of the spatial distribution that changes light intensity.
Design a kind of Multi-function lighting device, comprise lamp source and optically focused reflector, the lamp source is positioned at the focus place of optically focused reflector, there is liquid crystal light valve in front at the optically focused reflector, liquid crystal light valve is connected with its control circuit, by regulating the voltage of control circuit, can change transmission or the scattering state and the degree of liquid crystal light valve.
Above-mentioned liquid crystal light valve is LCD plate or liquid crystal display film.Certainly, the dispersed high molecule liquid crystal body (PDLC that described LCD plate or liquid crystal display film can use positivity to show, English full name: Polymer Dispersed Liquid Crystal is down together) or net high-polymer liquid crystal (PNLC, English full name: Polymer Network Liquid Crystal is down together), also can be the dispersed high molecule liquid crystal body (PDLC) or the net high-polymer liquid crystal (PNLC) that show into negativity.
Above-mentioned light source is LED, CCFL (cold-cathode tube), fluorescent lamp, incandescent lamp, halogen tungsten lamp, gas-discharge lamp, iodine lamp, sodium vapor lamp, mercury vapor lamp and neon light.
As improvement to the said goods, the transmission region of described LCD plate or liquid crystal display film can be divided into two or more zones, scattering that each is regional or transmissive state are subjected to the corresponding control of its control circuit separately.
As further improvement, can include the memory of literal or pattern and/or literal at described control circuit to the said goods.In the memory of pattern and/or literal, prestore various required patterns or literal, in order to using.
Above-mentioned liquid crystal light valve comprises two ITO electro-conductive glass (also claiming ITO conductive flexible film), accompanies high molecule liquid crystal body (PDLC) or net high-polymer liquid crystal (PNLC) between two ITO electro-conductive glass; Difference extraction electrode A and electrode B on two electro-conductive glass, the electrode A in electrode A and electrode B and the control circuit ' and electrode B ' join; If any the circuit of memory (RAM), then also join simultaneously with the output of memory (RAM).
The present invention sets up liquid crystal light valve and correspondent control circuits thereof owing to having adopted on illuminating source, make by regulating the voltage of this liquid crystal light valve, and scattering or the transmissive state and the degree of change light source like this, can reach the purpose of the spatial distribution that changes light intensity.
In addition, device for realizing that said method provides is provided with liquid crystal light valve in the front of optically focused reflector, the structure that liquid crystal light valve is electrically connected with its control circuit, like this, by regulating the voltage of control circuit, band changes transmission or the scattering state and the degree of liquid crystal light valve, and having reached shot-light both can direct projection, purpose that again can scattering, this shot-light not only can long drive, and can recent photograph, and a lamp is used more.
Again, owing to adopted the memory that also includes literal or pattern and/or literal at described control circuit.In the memory of pattern and/or literal, prestore various required patterns or literal, in order to using.When being applied in the present invention on the flashlight, be to be used to indicate the direction of escapeway or some points for attention of bulletin people etc. at natural calamity power failure dark states such as earthquake take place.
