Detailed description of the invention
Below, be described with reference to the ligthing paraphernalia of accompanying drawing to the multiple embodiment of the present invention.In accompanying drawing entirety, give identical reference marks for identical or similar part and omit the description.
(the first embodiment)
As shown in Figure 1, the ligthing paraphernalia 10 of first embodiment of the invention possesses: appliance body 11, is steel plate system, is implemented white application; LED unit 12, is arranged on below appliance body 11; And transparent lamp shade 13, be arranged on before LED unit 12.
LED unit 12 is, below the appliance body 11 being formed as toroidal, has glass epoxy resin system, is formed as the LED-baseplate 14 of the toroidal similar to the profile of appliance body 11.
LED unit 12 is, is arranged the first LED unit portion 16 of multiple LED15 in the outer portion of LED-baseplate 14 with having toroidal, is arranged the second LED unit portion 18 of multiple LED17 at the internal ring portion of LED-baseplate 14 with having toroidal.At this, multiple LED15 and multiple LED17 is toroidal along the shape sealing of LED-baseplate 14.
As shown in Figure 2, appliance body 11 is, has the top board 19 be arranged on via fixed components such as not shown hook sealings on ceiling face 1, have outer panel 20, have interior plate 21 in the inner side of top board 19 in the outside of top board 19 on top.
Transparent lamp shade 13 is such as milky allyl resin system, has light transmission, abuts install with the outer panel 20 of appliance body 11 and interior plate 21.
As shown in Figure 3, ligthing paraphernalia 10 is, below the central portion side of appliance body 11, is provided with being formed as box shape and implementing the platform cover 22 of white application of steel plate.
In platform cover 22, contain the power subsystem 23 be electrically connected with the not shown printed circuit that LED-baseplate 14 has.
Platform cover 22, owing to being implemented adularescent application, therefore has reflection function.
On platform cover 22, LED unit 12 is installed below.
And, reflection part 24 is installed below platform cover 22.
Reflection part 24, has the reflection part main body 25 be such as bent to form by thinner metal plate member, has recessed lateral reflection face 26 at the sweep of recessed side, has convex lateral reflection face 27 at the sweep of convex side.
Reflection part 24 is installed to be, and recessed lateral reflection face 26 covers multiple LED15 in the first LED unit portion 16 of outer portion.
Reflection part 24 is set to, and recessed lateral reflection face 26 and convex lateral reflection face 27, relative to the downward vertical direction of the LED15 of outer shroud and the LED17 of inner ring, comprise the scope of 0 ~ ± 90 degree.
As shown in Figure 4, reflection part 24 is, the shape that reflecting plate main body 25 is formed as making the reflector plate 28 of multiple equilateral shape to arrange, and has slit 29 between reflector plate 28.
In addition, reflection part 24 also may instead be metal and is semi-permeable resin-made, becomes and also can be formed as waveform shape.
Next, the optical characteristics of ligthing paraphernalia 10 is described.
By being powered by power subsystem 23, the LED17 in the second LED unit portion 18 thus from the printed circuit of LED-baseplate 14 to the LED15 in the first LED unit portion 16 of outer shroud and inner ring powers, and the LED15 of outer shroud and the LED17 of inner ring is luminous.
Light from the LED15 of outer shroud penetrates downward, by the recessed lateral reflection face 26 of reflection part 24 towards offside reflection.
Therefore, from the light of the LED15 of outer shroud, do not penetrate towards the transparent lamp shade 13 in direction immediately below LED15, therefore its brightness can not be larger than other parts of transparent lamp shade 13, not produce brightness disproportionation.
In addition, from the light of the LED17 of inner ring, a part penetrates towards the below of LED17, and the central portion towards appliance body 11 reflects by the convex lateral reflection face 27 of reflection part 24.
Therefore, from the light of the LED17 of inner ring, the central portion towards appliance body 11 penetrates, and does not more penetrate towards the transparent lamp shade 13 in direction immediately below LED17, and therefore its brightness can not be larger than other parts of transparent lamp shade 13, not produce brightness disproportionation.
Now, the light of the constant ratio through slit 29 in the light that reflection part 24 advances, penetrates towards transparent lamp shade 13 through reflection part 24, is adjusted thus by the reflection light quantity of the light of recessed lateral reflection face 26 and the reflection of convex lateral reflection face 27.
Above, according to the ligthing paraphernalia 10 of first embodiment of the invention illustrated, by reflection part 24, from the light of the LED17 injection of the LED15 of outer shroud and inner ring from below vertical direction reflected obliquely.
Therefore, according to ligthing paraphernalia 10, in transparent lamp shade 13, immediately below the LED15 of outer shroud and the LED17 of inner ring, the brightness of part can not be larger than other parts, therefore, it is possible to prevent brightness disproportionation, can become high-quality.
In addition, according to ligthing paraphernalia 10, by the slit 29 of reflection part 24, the light transmission constant ratio of the injection of vertical direction downwards of the LED15 of outer shroud and the LED17 of inner ring, remaining ratio is blocked.
Therefore, according to ligthing paraphernalia 10, in transparent lamp shade 13, immediately below the LED15 of outer shroud and the LED17 of inner ring, the brightness of part can not be larger than other parts, therefore, it is possible to prevent brightness disproportionation.
And according to ligthing paraphernalia 10, by reflection part 24, the part from the light of the LED17 of inner ring reflects towards the central portion of appliance body 11.
Therefore, according to ligthing paraphernalia 10, make the central portion of appliance body 11 and outside become equal bright, the inequality of light can be prevented thus.
