Detailed description of the invention
For making there is further understanding to object of the present invention, structure, feature and function thereof, embodiment is hereby coordinated to be described in detail as follows.
Please refer to Fig. 2, Fig. 2 illustrates situation when using the light fixture 100 of one embodiment of the invention to throw light on, and in figure, X, Y, Z represent three mutually perpendicular directions respectively.Light fixture 100 has multiple illuminating module, and such as light fixture 110 has three illuminating module 110,120 and 130, the design of light fixture 100 takes the concept that the different illuminating module of the present invention can have different light modulation ratio.In detail, light fixture 100 there is the field of illumination 22,24 and 26 that three illuminating module 110,120 and 130 correspond respectively to desktop 20, illumination (illuminance) wherein in field of illumination 22,24 and 26 can more than 200 lumens, but the present invention is not as limit, and can define with other specific lumen values the scope that field of illumination 22,24 and 26 should belong to, when the illumination in a certain region of desktop 20 is less than above-mentioned specific lumen value, then namely this region does not belong to the arbitrary field of illumination in field of illumination 22,24 and 26.The light produced due to illuminating module 120 and 130 is for the balanced effect of illumination of field of illumination 22, that is the light that produces of illuminating module 120 and 130 contributes to the illumination promoting field of illumination 22, therefore when the illumination of desktop 20 will be promoted, brightness (luminance) ratio of increasing of illuminating module 110 can increase ratio lower than the brightness of illuminating module 120 and 130, and in illuminating module 110,120 and 130, the brightness of arbitrary illuminating module increases ratio and can show with following formula table:
Brightness increases ratio=(B2-B1)/B1 × 100%
Wherein, the brightness of B1 for this reason before the increasing of illuminating module, the brightness of B2 then for this reason after the increasing of illuminating module.Because the brightness of illuminating module 110,120 and 130 and its power consumption are proportionate, therefore when promoting the illumination of field of illumination 22,24 and 26, the increase ratio of the power consumption needed for illuminating module 110 is lower than the increase ratio of the power consumption needed for illuminating module 120 or 130.Therefore, when promoting brightness (namely the increasing the brightness of illuminating module 110,120,130) of light fixture 100, by the luminance compensation effect of illuminating module 120 and 130, the increase ratio of the power consumption needed for illuminating module 110 does not need too much, therefore relatively can promote the overall energy use efficiency of light fixture 100, and make light fixture 100 have energy-conservation effect.
In addition, in the present embodiment, when light fixture 100 is 50 centimeters apart from the height H of desktop 20, length L2 and the width W 2 of field of illumination 22,24 and 26 entirety are about 90 centimeters and 50 centimeters respectively.Therefore the field of illumination 12 of the 50 centimeters of length formed compared to the light fixture 10 of Fig. 1, light fixture 100 is more suitable for the environment for use (such as: the environment using multi-screen) for needing broad field of illumination.
Please refer to Fig. 3 and Fig. 4, Fig. 3 is the schematic diagram of the light fixture 200 of one embodiment of the invention, and Fig. 4 is the functional block diagram of the light fixture 200 described in Fig. 3.Light fixture 200 has two illuminating module 210,220 and control circuit 250, and illuminating module 210 and 220 separates with dotted line 202 in figure 3.Illuminating module 210 and 220 has exiting surface 214 and 224 respectively, and exiting surface 214 and 224 is interconnected into an overall exiting surface.Control circuit 250 is coupled to illuminating module 210 and 220.In an embodiment of the present invention, when light fixture 200 being used in desktop 20 environment of Fig. 2, illuminating module 210 can be set to the first illuminating module and make illuminating module 210 correspond to field of illumination 22 by control circuit 250, and illuminating module 220 can be set to the second illuminating module and make illuminating module 220 correspond to field of illumination 24 by control circuit 250 simultaneously.Wherein, because of information devices such as main ornaments similar screen, keyboards on field of illumination 22, and field of illumination 24 is more convenient for read-write, therefore field of illumination 22 can be claimed for " information device use district ", and is called " writable area " field of illumination 24.Namely the exiting surface 214 of illuminating module 210 corresponds to field of illumination 22, and the exiting surface 224 of illuminating module 220 then corresponds to field of illumination 24.The light produced due to illuminating module 220 is for the balanced effect of illumination of field of illumination 22, therefore when promoting the illumination of desktop 20, the brightness of illuminating module 210 increases ratio and can increase ratio lower than the brightness of illuminating module 220.The increase ratio of the power consumption needed for illuminating module 210 does not need too much, therefore relatively can promote the overall energy use efficiency of light fixture 200, and makes light fixture 200 have energy-conservation effect.
In this embodiment, exiting surface 214 and 224 is adjacent curved surface, and the curvature of exiting surface 224 can be more than or equal to the curvature of exiting surface 214.When the curvature of exiting surface 224 is greater than the curvature of exiting surface 214, the scope that exiting surface 224 can irradiate can be strengthened, and then strengthen the area of the field of illumination 24 corresponding to it.Further, by the section of the summit A of exiting surface 214 216 with form an angle theta 1 by the section 226 of the summit B of exiting surface 224, and angle theta 1 can between 10 ° to 30 °.When angle theta 1 is larger, the range of exposures 222 of exiting surface 224 can be larger, and the area of field of illumination 24 corresponding to exiting surface 224 also can be larger.
In addition, in the present embodiment, light fixture 200 separately comprises substrate 290.Substrate 290 comprises first part 292 and Part II 294, and first part 292 and Part II 294 be corresponding two exiting surfaces 214 and 224 respectively.Wherein, multiple illuminators 240 of illuminating module 210 are arranged on first part 292 with the first density, and multiple illuminators 240 of illuminating module 220 are arranged on Part II 294 with the second density, and the first density and the second density may be the same or different.Such as, in an embodiment of the present invention, the first density is less than the second density, and when increasing the brightness of illuminating module 210 and 220, control circuit 250 can provide the recruitment of equal-wattage in each illuminator 240 on substrate 290.Because the power recruitment of each illuminator 240 is identical, and the first density is less than the second density, therefore when control circuit 250 increases the brightness of illuminating module 210 and 220 and makes desktop overall brighten, the brightness of illuminating module 210 increases and increases ratio, to make the illumination of field of illumination 22 lower than the illumination of field of illumination 24 than regular meeting lower than the brightness of illuminating module 220.In another embodiment of the invention, first density then equals the second density, and when increasing the brightness of illuminating module 210 and 220, the recruitment that control circuit 250 is provided in the power of the illuminator 240 on first part 292 can be less than the recruitment of the power of the illuminator 240 be provided on Part II 294, and then the brightness of illuminating module 210 is increased increase ratio, to ensure the illumination of the illumination of field of illumination 22 lower than field of illumination 24 than regular meeting lower than the brightness of illuminating module 220.In an embodiment of the present invention, illuminator 240 is light emitting diode (Light-Emitting Diode, LED).Such as, but the present invention is not as limit, and illuminator 240 can be the element that other can be luminous: tengsten lamp, vacuum fluorescent tube etc.
In an embodiment of the present invention, control circuit 250 drives multiple illuminators 240 of illuminating module 210 and 220 respectively with alternating current.And in an alternative embodiment of the invention, control circuit 250 drives multiple illuminators 240 of illuminating module 210 and 220 respectively with direct current, and control circuit 250 is by the brightness changing the size adjustment illuminating module 210 flowing through the DC current flow of multiple illuminators 240 of illuminating module 210, and by changing the brightness of the size adjustment illuminating module 220 flowing through the DC current flow of multiple illuminators 240 of illuminating module 220.When driving multiple illuminators 240 of illuminating module 210 and 220 respectively by direct current, illuminating module 210 and 220 can be avoided to glimmer, and then the problem that human eye can be avoided easily to feel fatigue when long-time use because of the flicker of illuminating module 210 and 220.
