Description
Technical field
The present invention relates to illumination optical field, espespecially a kind of reflectoscope.
Background technology
Reflectoscope (reflector lamp) is a type of bulb, and its inside has reverberation or overcover, is used for the front end of light reflection to the bulb luminous component.Reflectoscope can scatter or be directed to the specific region with light, according to (the American National Standards Institute of ANSI, ANSI) definition, the luminous component of reflectoscope has four kinds of basic configurations: reflection-type (reflector, the parabolic shape reflection-type of R), aluminizing (parabolic aluminized reflector, PAR), protruding reflection-type (bulged reflector, BR), elliptical reflecting type (elliptical reflector, ER).These bulbs are mainly used in floodlighting, spotlighting, downward focus irradiation etc.
Operation principle based on fluorescence gas discharge and electromagnetic induction, a series of electrodeless fluorescent reflectoscopes are developed and introduce to the market, for example DuluxELR80, the A19 of Ou Silang (OSRAM) and BR30 (United States Patent (USP) 7119486B2, Valery A.Godyak etc.), Genura R80 (the European patent 0660376A2 of GE, Roberts, Victor David etc.) and the QL (United States Patent (USP) 5130912, Friederichs etc.) of Philip (Philips).So-called fluorescent reflection lamp is exactly to fill fluorescence gas in the luminous component of reflectoscope, and the ultraviolet light that the transition of fluorescence gas is sent changes visible light into, is used for illumination.Compare with electrode fluorescence lamp, electrodeless florescent lamp has faster shinny, the life-span is longer advantages such as (15000 hours).
In the electrodeless fluorescent reflectoscope, the R80 light fixture has internal layer reflectance coating and outer layer plastic shell, it is compared from the compact fluorescent lamp (compact fluorescent lamp with integrated ballast CFLi) of ballast with the modified band of standard, can provide better light to distribute.These low-yield R80 reflectoscopes design in order to replace traditional incandescent R80 reflectoscope, and the energy saving that common R80 lamp can be used surpasses 75%.Fig. 1 is the schematic cross-section of the bright electrodeless R80 reflectoscope of the Central European department of prior art.As can be seen from Figure 1, comprise from the electrodeless R80 lamp of ballast: E27 pedestal 101, ballast parts 102, luminous component (burner), lamp housing (cover) 105.Wherein, luminous component comprises: gas discharge chamber 103, arc chamber shell 104, reentrant cavity 106, the arc chamber shell is made by light transmissive material (such as glass etc.), scribbles reflectance coating at the inwall of arc chamber shell near the position of ballast parts 102.In addition, ballast parts 102 comprise: ballast casing and be placed on ballast in ballast casing, this ballast is that the couplers (comprising FERRITE CORE and winding) in reentrant cavity 106 provide high-frequency electric field.Like this, the gas in gas discharge chamber 103 will be transferred electric forming circular induced current field at electromagnetic induction.Further, Fig. 2 a illustrates the enlarged diagram of R80 lamp part.Wherein, dotted line 201 is the inwall of arc chamber shell 104, and dotted line 202 is the outer wall of arc chamber shell 104; Dotted line 203 is the inwall of lamp housing, and solid line 204 is the outer wall of lamp housing; Dotted line 205,206 and 207 illustrates the size of lamp housing.Particularly, dotted line 205 is the height of lamp housing, and dotted line 206 is the bottom radius of lamp housing, and dotted line 207 is the second radius of lamp housing.Fig. 2 b is the sectional axonometric drawing of R80 lamp part.Can find out, the shape of lamp housing 105 and arc chamber shell 104 is similar, and lamp housing 105 is wrapped in luminous component, and exposes a transmission region for luminous component.
Fig. 3 is the light distribution measuring results of existing R80 lamp.As can be seen from Figure 3, light is Rotational Symmetry and distributes, and is maximum at the light intensity that the intrafascicular heart of lamp (i.e. 0 ° of angle) sends, and is 267.8 luminous intensities (cd).The angle folded with the intrafascicular heart of lamp is larger, and light intensity is less.Light intensity in position, ± 60 ° of angles is about 140cd, and total light output only has 61% to drop in hexagonal angle.
It may be noted that will there be a new regulation in European Union, only have the bulb of exporting in the solid angle of π surface of sphere (sr) (cone that is equivalent to a hexagonal angle) when the light that is not less than 80%, just allow to be classified as reflectoscope.Wherein, hexagonal angle refers to the drift angle of cone.If this condition can not satisfy, just must meet the requirement of " efficiency grade A ", this needs bulb to reach at least 1371 lumens (lm) (perhaps, reaching 1297lm at 22W) at 23 watts (W).
But up to now, prior art all can't converge light better.Further, prior art all can't satisfy the new regulation of European Union, such as the light in hexagonal angle output is not less than 80%, perhaps makes a 22W bulb reach the light output etc. of 1297lm.

The specific embodiment
For making purpose of the present invention, technical scheme and advantage clearer, referring to the accompanying drawing embodiment that develops simultaneously, the present invention is described in more detail.
The light that sends for the luminous component that makes bulb more converges, and the present invention proposes a new reflectoscope design, comprising: pedestal, ballast parts, luminous component and lamp housing.Wherein, lamp housing can be made by light-proof material (such as plastics), comprises first and second portion; Luminous component is divided into first area, second area and the 3rd zone.
The first of lamp housing is used for the first area around luminous component, makes the first area of this luminous component light tight; The second portion of lamp housing is used for the second area formation of luminous component is blocked, and the 3rd zone of luminous component is exposed.It may be noted that around with the degree of being close to of blocking be different.The first area of luminous component is close to by the first of lamp housing, this first area is formed parcel, but the second portion of lamp housing is not extremely pressed close to the second area of luminous component.The first and the second portion that it may be noted that lamp housing are one, and wherein the shape of first and prior art are similar, and larger variation occurs the shape of second portion.It is not distinguish for alteration of form part and shape are not changed partly that lamp housing is divided into that two parts are described.
In addition, the inwall of the second portion of lamp housing scribbles reflectance coating, and this reflectance coating is used for reflection and projects the light of this second portion from luminous component, and these light are appeared from the 3rd zone of luminous component.That is to say, whole lamp housing just is partially coated with reflectance coating.
In one embodiment of the invention, the first area of luminous component can be called light tight zone, and second area is called zone line, and the 3rd zone is called transmission region.
Below lifting electrodeless R80 lamp is example, illustrates the novel lamp housing design for reflectoscope, makes light more converge in certain angle, such as the light output that reaches at least 80% in hexagonal angle.Certainly, can adjust according to the industry needs for the requirement of convergence angle, be no less than light output of 80% etc. such as requiring to reach in 100 ° of angles.In order to allow more light enter in hexagonal angle, according to the design of electrodeless R80 lamp of the present invention as shown in Figure 4, the difference between this novel lamp housing and existing lamp housing is: novel lamp housing is larger, and the subregion inwall scribbles reflectance coating.The first 4051 and the second portion 4052 that divide lamp housing take solid horizontal line 4053 as the battery limit (BL), the first 4051 of lamp housing is around the first area of luminous component, and the second area of 4052 pairs of luminous components of second portion of lamp housing forms and blocks.Particularly, Fig. 5 a is the enlarged diagram of reflectoscope shown in Figure 4 part; Fig. 5 b is the sectional axonometric drawing of reflectoscope shown in Figure 4 part.Can find out from Fig. 5 a, reflectance coating 501 applies a week along the inner surface of the second portion 4052 of lamp housing, and solid line 501 illustrates the height of reflectance coating.Dotted line 502 is the height of novel lamp housing, and dotted line 503 is the bottom radius of novel lamp housing, and dotted line 504 is the second radius of novel lamp housing.Compare with Fig. 2 a, the length of dotted line 207 and dotted line 504 is suitable, but the length of dotted line 503 is greater than dotted line 206.That is to say, the second portion of novel lamp housing is no longer around luminous component, blocks but only luminous component is formed.
The manufacture process of novel lamp housing is as follows: the bottom sides angle part of pruning existing lamp housing 105, the inclined-plane of lamp housing is made the bottom of its more close luminous component to downward-extension, and also namely increase the height of lamp housing.Like this, compared to the prior art, the transmission region of luminous component diminishes relatively.Then, coat reflectance coating (can be aluminium or dichroic material) at the inner surface of extension.This reflectance coating can reflect the light outside hexagonal angle, changes its direction and makes it downward.Correspondingly, the light intensity within hexagonal angle can increase, and more light output will be controlled in hexagonal angle.Certainly, lamp housing after downward-extension, can be done a less fillet in the bottom of lamp housing, the end that makes lamp housing is no longer sharp-pointed.
Can find out, although measurement result shows existing electrodeless R80 lamp and only has an appointment 61% light output in 120 ° of scopes, but by will have now lamp housing to downward-extension and within it side coat reflectance coating, just can be redirected to the light outside hexagonal angle making it downwards, thereby more light are focused in hexagonal angle.This solution just can make it meet the oriented lamp criteria for classification as long as existing electrodeless R80 lamp is simply transformed, and this design concept also can be applicable in other electrodeless and electrode reflectoscopes.
It is pointed out that in order to satisfy 80% requirement of light output in hexagonal angle, be not easy to determine lamp housing by manual calculation and how long need to extend, need to coat the parameters such as reflectance coating in much areas.Therefore, need to use the technology such as ray trace and optical simulation, analyze the lamp housing impact that distribution causes on light with reflectance coating.
At first, by importing the physical dimension of existing R80 lamp, and define the optical property of the glass that uses in this lamp, plastics, fluorescent material, create an optical simulation model.The intensity distribution result that obtains by optical simulation is as shown in Fig. 6 a, and maximum intensity is 262cd and the beam center that sends at lamp, and the intensity at ± 60 ° of angles is about 140cd, account for total light output approximately 62% light in hexagonal angle.Can find out, these simulation results and measurement result shown in Figure 3 are comparatively identical.Therefore, this optical model can be considered as the Rational Model to the R80 lamp, and the change that can design on this basis is used for further analyzing.That is to say, above-mentioned optical model through checking can be used for analyzing the light changes in distribution that novel lamp housing that the present invention proposes brings, and provides guidance for the size design of lamp housing.In addition, Fig. 6 b is the light path schematic diagram of the luminous component of existing R80 lamp.Can find out, because lamp housing is light tight, there is not light in the lamp housing upper area that is wrapped in luminous component.But there is light in lamp housing edge and comparatively disperses.
Secondly, change the size of lamp housing, carry out the light distributed simulation.Fig. 7 a illustrates the light distribution with the electrodeless R80 lamp of novel lamp housing that obtains by optical simulation, and the base diameter of this novel lamp housing is that 104 millimeters, the height of reflectance coating are 39 millimeters.Find out from Fig. 7 a, the light intensity that the intrafascicular heart of lamp sends is maximum, is 370cd; Intensity at ± 60 ° of angles is about 175cd; Approximately the output of 80% light is in hexagonal angle.As seen, the Novel electrodeless R80 lamp of the present invention's design can meet European Union for the new regulation of oriented lamp issue.In addition, Fig. 7 b is the light path schematic diagram of reflectoscope shown in Figure 4, compares with Fig. 6 b, and in Fig. 7 b, the light of lamp housing edge more converges.In specific design, make the base diameter of lamp housing be not less than 104 millimeters, the height of reflectance coating and be not less than 39 millimeters, just can obtain compared to the prior art better convergence effect.Certainly, after obtaining the preferred dimensions of novel lamp housing, can make R80 lamp model and carry out the light distribution measuring for material object, in order to the application of novel lamp housing design in the electrodeless R80 lamp of reality assessed.
Especially, embodiments of the invention are applicable to the bulb that miror lamp (such as R80) or protruding miror lamp (such as BR30) etc. have independent lamp housing, and namely lamp housing and luminous component are not one.For miror lamp, its luminous component has parabola part or paraboloid part under maximum gauge.For protruding miror lamp, the sweep of its luminous component most of side is greater than the radius of this luminous component, and center of curve is positioned at the center of plane of greatest diameter.
Can find out, the technical scheme that the present invention proposes has following at least one advantage:
1, the design of new lamp housing makes reflectoscope (such as electrodeless R80 lamp) can meet the requirement of oriented lamp, and easily realize, with low cost.
2, new lamp housing design is the improvement to existing design, is easy to put into industry manufacturing.
3, the design concept with the lamp housing of reflectance coating that proposes of the present invention is applicable to various electrodeless and electrode reflectoscopes, makes it satisfy potential oriented lamp requirement.Wherein, the height of the size of lamp housing and reflectance coating can be determined with reference to optical simulation and experimental result.
The above is only preferred embodiment of the present invention, and is in order to limit the present invention, within the spirit and principles in the present invention not all, any modification of making, is equal to replacement, improvement etc., within all should being included in the scope of protection of the invention.
