A light source apparatus having, in spite of its simple and compact construction, enhanced efficiency of condensing light in a predetermined small diameter region. The light source apparatus has a light emitting tube (20) with a pair of main electrodes (21, 22) and has a reflector (30) for reflecting light emitted from the light emitting tube (20). The electrode axis O1 of the main electrodes (21, 22) intersects with the optical axis LA of the emitted light. In the reflector (30) are formed a first reflector section (31) and a second reflector section (32). The first reflector section (31) has a spherical surface with its center at a light emitting point L0 of the light emitting tube (20), and the second reflector section (32) has a curved surface different from that of the first reflector section (31). The reflector (30) also has a light condensing body (40) for condensing light that is emitted from the light emitting tube (20) to places other than the second reflector section (32) and irradiating the condensed light to a predetermined direction or region.

A laser crushing device (3) is provided with: a waveform control unit (27) that pulses laser light excited from a laser light source (21) and adjusts the output of the pulsed laser light; and a fiber tip (23a) that emits the laser light, the output of which has been adjusted by the waveform control unit (27), to urinary calculi (S) in the liquid, and the waveform control unit (27) switches the output of the laser light to a second period in which the output monotonically decreases at a gradient greater than a predetermined gradient after a first period in which the output monotonically increases.

The invention provides a lighting apparatus of a riding type vehicle, wherein the light source type of the lighting apparatus is not restricted, the radiating light is not blocked by the key carried by the hand of a rider, and the key switch can be effectively lightened. A plane inclined portion (45) and a plane vertical portion (46) are formed on a leg guard plate (25) arranged opposite to a passenger, the inclined portion (45) is inclined foward wherein the portion above the vehicle is fronter than the portion below the vehicle, and the vertical portion (46) is vertically arranged from the inclined portion (45) to the portion above the vehicle. The portion lightened by the switch light (80) is positioned at the opening (45a) of the inclined portion (45) to be matched with a combined switch (50). The lighting surface of the switch light (80) is positioned at the opening (46a) of the vertical portion (46) to be matched with the switch light (80). When observed from the side of the vehicle body, the axis direction SJ of the lock core (56) of the combined switch (50) is crossed with the radiating direction PJ of the switch light (80) behind the vehicle body, and thereby the combined switch (50) is lightened from the front sideof the vehicle body.

The invention relates to a substrate inspection device and a transmission illuminating device for the substrate inspection device. The substrate inspection device can prevent infrared light from an infrared light source from entering a camera without passing through the substrate, so that the substrate can be accurately inspected. The shape and arrangement of the infrared light source are set so that the field of view of the infrared light source of the charge-coupled device camera is covered by the field of view of the substrate of the charge-coupled device camera. Furthermore, by virtue of the Fresnel lens, the irradiation angle of the infrared light emitted from the light emitting diode element disposed near the edge of the infrared light source is deviated toward the edge direction of the substrate. In addition, the intensity of the infrared light irradiated from the infrared light source to the substrate on the edge region of the substrate is greater than the intensity of the infrared light on the central portion of the substrate.

PROBLEM TO BE SOLVED: To provide an illumination device for plant cultivation using artificial light, which can efficiently irradiate leaves at a lower section of the plant even when applying high intensity light.SOLUTION: The illumination device for plant cultivation includes: a main light source which emits monochromatic light or mixed-colored light of which wavelengths are between 400 nm or more and 700 nm or less and photosynthesis photon flux density is at 200 μmol / m / s or greater; and a far-infrared light source which emits far-infrared light. The main light source and the far-infrared light source include semiconductor light-emitting elements.

The invention relates to the technical field of liquid crystal display, in particular to a backlight module and a liquid crystal displayer. The backlight module sequentially comprises a printed circuit board, a reflector plate, an LED light source and a diffusion plate from bottom to top. First protruding points are arranged on the light-in face, facing the LED light source, of the diffusion plate and around the projection, within the light-in face, of the LED light source. The first protruding points can conduct reflection diffusion on an illumination area, on the diffusion plate, of the LED light source, eliminate projection dark spaces and prevent light source gathering, so that the distribution of a light-emitting area on the diffusion plate is more uniform. Meanwhile, the LED light source can be independently controlled, local light control can be better achieved, and accordingly the display quality of a high-dynamic-comparison image is improved. The reflector plate can reflect leaking light again so that the light can irradiate the diffusion plate again, accordingly the utilization rate of the light source is increased, the light mixing distance is increased, and thinning design of the liquid crystal displayer is achieved easily.
