摘要:
Provided are a lighting lens and an illumination apparatus including the same that can improve color rendering properties and prevent reductions in performance of a light flux controlling member and in illuminance on a surface to be illuminated when a pseudo-white LED is used. This lighting lens (1) includes a color adjustment unit (14) that contains a color adjusting material, is excited by light emitted from an LED (2) and emits light in a color different from the light-emitting color of the LED (2). The color adjustment unit (14) is disposed at a portion through which sub-rays other than main rays pass and not at a portion through which the main rays pass, the main rays being rays having a luminous intensity equal to or more than a predetermined percentage of the maximum luminous intensity.
摘要:
A light-emitting device combining a first luminous flux control member having a total reflection surface and emitting light from an emission surface in a narrow angle range centered mainly on an optical axis, and a second luminous flux control member arranged to surround the total reflection surface of the first luminous flux control member. The second luminous flux control member (102) of the light-emitting device is provided with a second incidence surface (126a) and a second emitting surface (126b). Of the light emitted from the light-emitting element (200), the light incident to the second incidence surface (126a) is within a range of angles θ larger than a largest angle to the optical axis of the light incident to the first luminous flux control member (101). The second emitting surface (126b) controls the light incident to the second incidence surface (126a) to have light distribution characteristics different from those of the light emitted from the first luminous flux control member (101), and emits the light.
摘要:
Disclosed is a light emitting device to reduce the number of components and elements of a light emitting device and a lighting device having the light emitting device, and simplify and miniaturize the structures of these devices. With this light flux controlling member (4), a total reflecting surface (12) functions like a reflecting member, light from a light emitting element (LED, for example) (3) that is incident from an input surface (13) and that arrives at the total reflecting surface (12) is total-reflected by the total reflecting surface (12) toward the output surface (11) side (including a first output surface (11a) and second output surface (11b)), and the illuminating light from the second output surface (11b) is superimposed upon the illuminating light from the first output surface (11a), so that the light from the light emitting element (LED, for example) (3) is used efficiently and illuminates the illumination target surface (6) over a wide range.

A lighting device preventing an illumination variation on a surface to be irradiated. The lighting device has a first light emitting surface section (102a) which is a surface formed by rotating a bus with a central axis as a rotation axis in a first angle area (−θ1≦θ≦θ1) of an angle (θ) relative to a cross section of the bus which is an intersection line with the cross section perpendicular to a surface (801a) to be irradiated and including the central axis of a lighting lens (100), a second light emitting surface section (102b) formed in a second angle area (θ1≦θ≦180° and −180°≦θ≦−θ1) of the angle (θ) so that a light flux emitted toward the surface (801a) increases as compared with the case where the first light emitting surface section (102a) is formed in a whole-angle area (0°≦θ

摘要:
A fluid handling apparatus 10 has a plurality of fluid handling subassemblies 16 arrayed on a plate body 12. Each of the fluid handling subassemblies includes: an injecting section 26 for injecting a fluid; a fluidized section 28 for allowing the fluid to continuously flow downwards; a fluid housing chamber 30 for receiving the fluid from the fluidized section; a wall portion 20 formed between the fluid housing chamber and the fluidized section; slits 20b for allowing the fluid to enter the fluid housing chamber; and a surface-area increasing means 22 for increasing the area of a contact surface with the fluid in the fluidized section. The slits extend from a lower end positioned in the vicinity of the lower end of the fluidized section, to an upper end higher than the upper end of the fluidized section, for allowing the injecting section and fluidized section to be communicated with the fluid housing chamber.

摘要:
A fluid handling unit 16 has an inside cylindrical portion 16c which is arranged in an outside small-diameter cylindrical portion 16b so as to be eccentric with respect to the outside small-diameter cylindrical portion 16b, and a plurality of slits 16d for establishing a communication between an inside fluid housing chamber 30 and an outside fluid housing chamber 28. The most part of liquid in the inside fluid housing chamber 30 enters the outside fluid housing chamber 28, in which the height of the liquid level varies in circumferential directions, when the quantity of the fed liquid is not larger than a predetermined quantity. The liquid in the outside fluid housing chamber 28 enters the inside fluid housing chamber 30 when the quantity of the fed liquid exceeds the predetermined quantity.
