The invention discloses an LED projecting light (8), comprising a casing (1), a light outlet plate (6), and a plurality of LEDs (3), wherein the LEDs (3) are collected in the casing (1), the light outlet plate (6) is fixed on the casing (1) to seal the LEDs (3) in the casing (1), and the LEDs (3) are arranged in the casing (1) taking on external convex arc surface towards the direction of the light outlet plate (6). The invention enables the LED component 3 to be arranged in the LED projecting light (8) taking on external convex arc surface through arranging an arc-shaped base body (160) in the LED projecting light (8), enables the lighting angle of the LED projecting light (8) to be greatly enlarged under the condition of enlarging the volume of the current LED projecting light, thereby increasing the light area of the LED projecting light (8), and further effectively improving the projecting effect of the LED projecting light (8) under the condition of no increasing costs.

A heating device for a vehicle is provided with a radiation-heat generating unit for generating radiation heat, a first light-distributing unit for converting irradiation directions of the radiation heat into a substantial single irradiation direction, and a second light-distributing unit for distributing the radiation heat to at least one heating object in a passenger compartment of the vehicle. The second light-distributing unit slantways intersects the radiation heat which has the substantial single irradiation direction converted by the first light-distributing unit.

First laser light is irradiated (energy density of 400 to 500 mj / cm2) to a semiconductor film 102 in an atmosphere containing oxygen in order to obtain a semiconductor film 102b having large depressions and projections on the surface. Then, an oxidized film 105a formed by the irradiation of the first laser light is removed. After that, an inert gas with an oxygen density of 10 ppm or below is blown thereto, and, at the same time, second laser light is irradiated thereto (the energy density is higher than that of the irradiation of the first laser light). Thus, the surface of the semiconductor film 102b is flattened, and a semiconductor film 102c having fewer depressions and projections on the surface can be obtained.

Disclosed are a microbe inactivation processing device that can perform inactivation processing of microbes, while damage to human body cells is prevented or inhibited, with an efficient use of light emitted from a light source and the obtainment of a large effective irradiation area. Also provided are a cell activation processing device that can reliably activate target cells with high efficiency. The microbe inactivation processing device includes: a light source configured to emit light having a wavelength within a wavelength range of 190 nm to 237 nm; a power supply unit configured to supply electric power to the light source; a control unit configured to control the power supply unit; and an optical filter. The microbe inactivation processing device is configured to perform inactivation processing of a target microbe by applying the light emitted from the light source through the optical filter. When the light emitted from the light source is incident at an incident angle of 0°, the optical filter transmits at least a part of ultraviolet light having a wavelength within a range of not lower than 190 nm and not more than 230 nm, and transmits at least a part of ultraviolet light having a wavelength within a range of more than 230 nm and not more than 237 nm, and the optical filter blocks transmission of ultraviolet light having a wavelength out of a wavelength range of not lower than 190 nm and not more than 237 nm.
