Description
Technical field
The present invention relates to concert, various activities scene etc. (being commonly referred to as " concert etc. " in the present specification) mainly by
The light-emitting instruments such as torch (penlight, pen shape photophore), glo-stick (stick light) that spectators, participant use are (at this
In specification referred to as " torch "." torch " in the present invention refers to related all light-emitting instruments.).
Background technique
Torch is held in meeting-place such as concerts by spectators, and so that it is shone, light carry out using.This is for being, for example, to sing
Hand is cheered or many spectators are used in the same manner torch to form a body-sensing.Initially, it is only bar-like and only can be with bill
There is torch, capable of emitting varicolored torch, such as lamp decoration/secondary rainbow of the shape with the complexity such as heart, star later in coloured light
The torch etc. that rainbow lamp flashes like that caters to the demand of the novel torch of the enterprise planning of each concert etc., purport etc., in addition, spectators couple
In torch demand also in diversification.
Recently, such as in each member have in respective concert of idol combination for representing color etc., it generally will basis
The progress of performance makes torch colour developing shine to be expressed support for or when playing specific song with the representative color of each member
So that torch colour developing is shone with specific color, needs can use a torch to issue the light of multiple colors (in this specification
In be known as " polychrome torch "), it is accordingly required in particular to the torch of available multiple illuminant colours.
Currently, light source uses light emitting diode (LED) in most torches.As polychrome torch, propose such as patent text
It offers 1 and carries this 3 light emitting diodes of red light emitting diodes, blue LED and green LED like that
(RGB), can be developed the color luminous torch with various colors.This is to mix the light issued from the light emitting diode of RGB, adjust
It saves and obtains the torch of illuminant colour, what is utilized is that (Jim Glassmans such as trichroism of color are fixed for the trichromatic principle of so-called light
Rule).
If being believed that the light emitting diode using RGB, theoretically can be obtained by merely with 3 light emitting diodes
With for example unlimited kind of tone come the luminous torch that develops the color.Recently, 3 LED (RGB) are packaged into one so-called full color
LED is all the fashion, and design, production are in more convenient situation based on trichromatic polychrome torch.
However, as described below, may not actually be easy to obtain the colour mixture of the light emitting diode based on 3 colors in torch
Delicate balance.
Even if in addition, initially obtaining above-mentioned balance and obtaining desired illuminant colour, but the state might not continue.
The power supply of torch is battery, and electric power is limited, can not be supplied electric power long-term and stably, due to the consumption of battery caused by illuminant colour
The dysequilibrium of (colour mixture) is significant, as a result can not obtain desired color.According to size (the less knob of electricity of dry cell
Detain battery etc.), the usage mode of torch, the period that can not obtain the balance of illuminant colour (colour mixture) can unexpectedly arrive quickly
Come.
The former the problem of, is mainly considered the problem of adjusting/setting of control unit, from how to carry out control or
It programs to obtain the balance of the colour mixture of RGB and obtains desired this viewpoint of color and set out and attempt to solve (in addition, patent
There are some associations with the above problem for document 2).However, there is also realize that a large amount of colour developing (or even needs using torch recently
Will be close to the colour developing of 20 kinds of colors) demand, for using RGB delicate adjusting, programming and steadily obtain illuminant colour
For different (such as differences of aubergine and pink), it's hard to say certain success.
It is general it is contemplated that using booster circuit, current control circuit (device) as the method for solving the problems, such as the latter.So
And, it is difficult to exist in size, weight and assembles such circuit in the torch of limitation, it is also unrealistic from cost face.Furthermore
Since torch is usually brandished use, it can also make mistakes and fall sometimes, so having to that boosting electricity will be present to a certain extent
A possibility that road etc. is damaged counts, and if assemble booster circuit etc., it is likely to increase the failure of torch instead
Reason.
Current situation is, the problem of about the latter, the effective measures for keeping the balance of the colour mixture based on RGB lasting are simultaneously
It is not present, therefore, in the case where currently utilizing RGB, if battery consumption can not obtain desired tone to a certain degree,
Then no matter still whether remaining has electric power in battery, and the user of torch has to more be brought reply using new battery.
But since this will waste remaining electric power in battery, so economic loss can be generated, in addition to this, in concert etc.,
It is not easy to replace battery in performance, for wanting to avoid the torch user of such case as far as possible, can also generate not
Just improper in this reality.
In polychrome torch, it has been proposed that how using RGB light emitting diode can issue desired color (on
The patent document 2 in face), how user can control the schemes such as colour developing (patent document 3, patent document 4), but can not solve
The certainly corresponding scheme of the above problem.

Specific embodiment
Hereinafter, embodiment involved in polychrome torch of the invention is concretely demonstrated referring to attached drawing.
(embodiment 1)
Polychrome torch of the invention has illumination region and handle part.Fig. 1 is to indicate torch 5 of the invention (referring to Fig. 2)
The figure of one embodiment of handle part 1.The handle part 1 of torch of the invention has light source portion 2 and control unit 3.In handle part 1
On can in addition be arranged accommodate battery 6 battery compartment etc..
When using torch, as an example, as shown in Fig. 2, usually installing the shapes such as rodlike on the top of handle part
Cover as illumination region 4 use.In addition, above-mentioned cover then can usually be replaced if it is same size.
Light source portion 2 is configured to have red light emitting diodes, green LED, blue LED, yellow hair
Optical diode and white light-emitting diode.In general, each light emitting diode (7A, 7B etc.) is disposed on the substrate, and by they
Configure the inner upper in handle part 1.The configuration of light emitting diode will be described below.
Control unit 3 has the control that is luminous and respectively being controlled to each light emitting diode in the light source portion 2
Program etc..Program is controlled so that each light emitting diode individually with specific colour light emitting or makes multiple light-emitting diodes
Pipe shines and mixes them and is programmed to carry out luminous mode with specific color.
It is configured to, can get multiple illuminant colours in 1 torch, and is configured to can use switch 8 set in addition
Light desired by torch user is selected from the light of predetermined tone.
It is configured to, at least can get in the colour mixture of the light issued from multiple light emitting diodes will be from white light-emitting diode
The light of sending and the illuminant colour that is obtained by mixing of light issued from the light emitting diode except it or will be from Yellow luminous two pole
The illuminant colour that the light that pipe issues is obtained by mixing with the light issued from the light emitting diode except it.
As an example of the former (colour mixture with the illuminant colour of white light-emitting diode), such as it can enumerate and send out white
The illuminant colour colour mixture of optical diode and blue LED obtains nattier blue illuminant colour.White is sent out in addition, can enumerate
The illuminant colour colour mixture of optical diode, red light emitting diodes and blue LED, to obtain lilac illuminant colour.
If for example being described as a result, with above-mentioned example, in the past in addition to that can only be finely adjusted by one side to green,
The nattier blue illuminant colour for being actually difficult to obtain or be difficult to keep its lasting except it is obtained with blue colour mixture on one side becomes
Easily obtain.Equally, however, it is difficult to which the lilac illuminant colour of acquisition becomes easy acquisition.
In addition, by the way that luminous from white light-emitting diode is independently mixed in colour mixture, additionally it is possible to realize so far
Until be difficult to show difference multiple homology colors (for example, close to blue light blue and more whitening light blue) colour developing.
As the example of the latter's (colour mixture with the illuminant colour of yellow light-emitting diode), such as it can enumerate and send out yellow
The illuminant colour colour mixture of optical diode and green LED obtains the illuminant colour of yellow green, is further mixed into white hair to it
The illuminant colour of optical diode obtains the illuminant colour etc. of pistac.
It, theoretically can only be by 3 luminous two from RGB if for example being described as a result, with above-mentioned example
Pole pipe it is luminous on one side be finely adjusted section, while carries out colour mixture obtain and actually be very difficult to acquisition yellow green hair
It is photochromic to become easy acquisition.In addition, by the way that the illuminant colour of white light-emitting diode is directly carried out colour mixture, additionally it is possible to easily obtain
It obtains and shows different and the previous pistac that can not individually shine anyway shine from the illuminant colour of yellow green
Color.
Furthermore even homochromy light emitting diode, for each light emitting diode there is also individual difference, electric power consumption is different
Fixed consistent, in addition to this, such as multiple red light emitting diodes also may not all shine as identical red.Therefore, even if setting
It is fixed to generate specific tone at shining for each diode is controlled in advance using control unit (control program etc.), also may not sometimes
The tone of (anticipation) desired by acquisition, above-mentioned risk is in the case where wanting using the delicate mixing of each light to obtain color
It further increases.
In the case where shine with white, if making RGB balancedly colour mixture, the hair of white theoretically can get
Light, but under actual conditions as described above, it is difficult to corresponding equilibrium is obtained, can actually be occurred in the case where being based on RGB
The color error ratio as the stronger white of green, blue stronger white.According to the present invention, without the colour mixture based on RGB/
Fine tuning, as long as and only making white light-emitting diode shine can be realized, and be easy to get the white for further achieving balance.
Equally, in the case where shine with yellow, according to RGB, theoretically may be used if by the red colour mixture with green
Shining for yellow is obtained, but actually, it may occur that the color error ratio as the stronger yellow of green, red stronger yellow.
In addition, if the delicate balance of colour mixture is broken, by orange-yellow difference obtained from the red colour mixture with green in the same manner as
It is different to be also difficult to be embodied.According to the present invention, without colour mixture/fine tuning based on RGB, as long as and only making yellow light-emitting diode
Shining can be realized, and be easy to get the yellow that balance for example significantly, is further achieved with above-mentioned orange-yellow difference.
Furthermore by making light source portion 2 have white light-emitting diode, for obtain as described above color (such as from
It is red obtained with yellow it is orange-yellow) light color (lighter is orange-yellow), also can be by simply being mixed to acquired color
The illuminant colour of white light-emitting diode and be readily derived.
In addition, in the past light multiple diodes in the case where making white, yellow color development and colour mixture is finely adjusted,
In contrast, according to the present invention, as long as due to merely making the independent color development of white light-emitting diode, yellow light-emitting diode
It realizes, thus it is compared with the past, power consumption when shining can also be inhibited.
According to the present invention, the luminous of 3 light emitting diodes from RGB is not mixed knifeedge, by independent
Light emitting diode shine and white light-emitting diode other than 2 light emitting diodes luminous colour mixture, can be obtained
Multiple illuminant colours.For example, only by the way that JIS light source colour just will can be obtained from the combination of the illuminant colour of most 2 light emitting diodes
Essential colour, red (R), Huang Hong (YR), yellow (Y), greenish-yellow (GY), green (G), bluish-green (BG), blue (B), purplish blue (PB), purple (P), red
Purple (RP), pink (Pk), white (W).
This is not only limitted to the difficulty or ease for combining or adjusting merely.I.e., it is possible to realize with distincter tone come be emitted in
Relationship colour match toward combination, adjusting according to colour mixture is easy to dim or fuzzy illuminant colour.For example, previous (RGB), Huang Hong
(YR, orange-yellow) can only make its colour developing by the red colour mixture with the light emitting diode of green, but according to the present invention, due to can
To realize colour developing by the way that color is easier mutually coordinated yellow and red light emitting diode colour mixture, so can be realized
Than in the past more bright-coloured illuminant colour.
By the illuminant colour to the illuminant colour so obtained directly mixture of white light emitting diode, can be easy and with fresh
Gorgeous tone obtains the illuminant colour for being difficult to that it is distinctively made to develop the color in the past.
Other important advantages of the invention are, in the past along with the consumption for the process, i.e. battery for using the time
And combined balance system is easy the secondary colours such as white, light blue, pink, yellow lost, even if from power supply current/voltage because
It is reduced using the process (consumption of battery) of time, and therefore luminance reduction, can also obtain more connecing with the illuminant colour of script
Close tone.The result of comparative experiments is shown below for several illuminant colours.
(1) white luminous
First, for previous torch, make the lumination of light emitting diode of RGB, adjusted using colour mixture, with voltage 4.5V, electric current
50mA issues white light.
On the other hand, for torch according to the present invention, equally only make white luminous two with voltage 4.5V, electric current 50mA
Pole tube light-emitting has obtained the illuminant colour of white.
Second, next, under make the voltage of two torches all drop to 3.2V, electric current all since the above-mentioned state lighted
When being down to 20mA, in previous torch, become with red illuminant colour (so-called orange red (salmon pink)).This
It is not obviously at least on the face of it white luminous.
In contrast, white luminous to remain unchanged although illumination slightly reduces in torch according to the present invention.
In other words this is exactly white luminous remain unchanged and brightness slightly reduces.
(2) bluish luminescence
First, for previous torch, make the lumination of light emitting diode of RGB, adjusted using colour mixture, with voltage 4.5V, electric current
41mA has obtained light blue (close to light blue) and has shone.
On the other hand, for torch according to the present invention, two pole of blue-light-emitting is equally made with voltage 4.5V, electric current 41mA
Pipe shines with white light-emitting diode and has obtained nattier blue illuminant colour.
Second, next, when making the voltage of two torches that 3.0V, electric current is all reduced to all to drop since the above-mentioned state lighted
When down to 4mA, in previous torch, become blue-green.This is not obviously at least on the face of it nattier blue illuminant colour.
In contrast, in torch according to the present invention, although illumination slightly reduces, bluish luminescence is kept not
Become.This is in the same manner as (1), and bluish luminescence remains unchanged and brightness slightly reduces.
(3) pink to shine
First, for previous torch, make the lumination of light emitting diode of RGB, adjusted using colour mixture, with voltage 4.5V, electric current
51mA has obtained shining for pink.
On the other hand, for torch according to the present invention, two pole of emitting red light is equally made with voltage 4.5V, electric current 51mA
Pipe shines with white light-emitting diode and has obtained the illuminant colour of pink.
Second, next, when making the voltage of two torches all be reduced to 3.0V, make electric current all since the above-mentioned state lighted
When being reduced to 18mA, in previous torch, become red green.This is not obviously at least the illuminant colour of pink on the face of it.
In contrast, in torch according to the present invention, although illumination slightly reduces, pink light emitting is kept not
Become.This with (1) etc. in the same manner as, pink light emitting remains unchanged and brightness slightly reduces.
(4) Yellow luminous
First, for previous torch, make the lumination of light emitting diode of RGB, adjusted using colour mixture, with voltage 4.5V, electric current
41mA has obtained the illuminant colour of yellow (close to the color of yellow).
On the other hand, for torch according to the present invention, equally only make Yellow luminous two with voltage 4.5V, electric current 41mA
Pole tube light-emitting has obtained the illuminant colour of yellow.
Second, next, when making the voltage of two torches that 3.0V, electric current is all reduced to all to drop since the above-mentioned state lighted
When down to 16mA, in previous torch, become orange-yellow.This is not obviously at least on the face of it Yellow luminous.
In contrast, Yellow luminous to remain unchanged although illumination slightly reduces in torch according to the present invention.
In other words this is exactly Yellow luminous remain unchanged and brightness slightly reduces.
Above-mentioned experimental example is the example enumerated, and other illuminant colours also can produce same difference.
According to above-mentioned experimental example it is found that in the past since no matter whether remaining can not all obtain to a certain degree of battery allowance is wished
The illuminant colour of prestige so battery must not be changed without, but in accordance with the invention it is possible to obtains desired illuminant colour.Therefore, can compare
Battery allowance was more efficiently used in the past, the replacement period of battery can be postponed.
For torch, illumination region no matter is bar-like or shape in addition to this, requires to make the light from light source portion
Entirety throughout the side of illumination region (cover) 4, top.In addition to this, by light mixing to obtain color, it is necessary to
Tone obtained is by top/side entirety of illumination to illumination region.That is, illumination region 4 has defined space on the inside of cover,
Side, the top of cover have area to a certain degree, and illuminant colour is needed all throughout these and obtained.However, carrying out self-luminous two
Pole pipe it is luminous not only with distance far from light source and it is dimmed, using multiple light emitting diodes luminous acquisition illuminant colour feelings
Under condition (such as using the luminous acquisition orange pale illuminant colour of each light emitting diode of red, yellow, white the case where),
The luminous dispersion of each light emitting diode can not obtain the illuminant colour realized by colour mixture throughout above-mentioned entirety.
From the above point of view, preferably each light emitting diode (7A, 7B etc.) is closely arranged.In set light-emitting diodes
In the case that pipe is 5, such as it can be adjacent to as shown in Figure 3 and be configured to approximate pentagon shaped, or as shown in Figure 4
Outside is configured at by 4 and is configured at its inside for one.
In addition, also sufficiently to shine arranging for the top of illumination region (cover) 4 as not only shining illuminant colour near light source
It applies, such as it is contemplated that lens for achieving the above object is set near light source portion.However, being configured to as in the present invention
Light emitting diode is not one, in addition and for example obtains using 5 and the hair obtained by colour mixture with tri- differences of RGB yet yet
In the case where photochromic, the part far from light source site is not only irradiated, it is also necessary to spread the entirety of illumination region (cover) 4 rather than part
Obtain the illuminant colour obtained by colour mixture.As the measure for coping with these points, in the present invention it is possible near light source portion 2
Illuminant colour auxiliary unit is set, and above-mentioned illuminant colour auxiliary unit future, the light of spontaneous optical diode carried out optically focused, in addition in colour mixture
In the case where mixed to obtain (desired) illuminant colour, and make obtain illuminant colour equably spread illumination region (cover)
Side/top entirety.The shape of illuminant colour auxiliary unit, spot position, light emitting angle (angle that side, top are covered in irradiation)
Etc. can suitably be determined according to configuration of the size of illumination region, length, shape or light emitting diode etc..
