[0089] figure 1 is a drawing illustrating the general structure of the first embodiment of the lighting device according to the present invention.

[0090] The lighting device 200 according to the first embodiment of the present invention includes a lighting unit 100 and a driving unit 11 .

[0091] The driving unit 11 provides light-emitting driving power to the lighting unit 100, and a full-range transformer may be used as the driving unit. The drive unit 11 is connected to a commercial power supply to convert electric power in the range of AC110 to 220V / 50Hz to 60Hz into a drive voltage of DC 12V (any voltage that can be used, such as DC 6V or DC 24V or alternating current), and then converts the converted drive The voltage is supplied to the lighting unit 100 .

[0092] The lighting unit 100 includes a back plate 15, a light emitting unit 21 having a plurality of light emitting diodes (LEDs) 17 arranged in a line on a wiring substrate 19 serving as a base, and a reflect...

[0135] Next, a second embodiment of the lighting unit according to the present invention will be described.

[0136] Figure 12 A perspective view of a lighting unit is illustrated, the reflective surface of which is formed by a smooth machined surface. Figure 13 It is shown Figure 12 A cross-sectional view of the reflector part is shown. Figure 14 is an explanatory view showing the distribution of illumination through a lighting unit whose reflective surface is formed of a smooth machined surface. In the following examples, the same reference numerals refer to Figures 1 to 6 Components that are the same as those shown, and descriptions thereof will be omitted.

[0137] In the lighting unit 300 according to this embodiment, at least one reflective surface (the parabolic mirror 25b and the flat mirror 27b) of the first and second reflective members 25 and 27 is formed of a smooth machined surface.

[0138] As the coating process to which the above reflection surfaces (...

[0145]Next, a third embodiment of the lighting unit according to the present invention will be described.

[0146] In this embodiment, a structure that performs wide range illumination is provided.

[0147] Figure 16 An explanatory view showing a lighting unit and an illuminance distribution through the lighting unit according to this embodiment.

[0148] The lighting unit 400 of this embodiment includes a plurality of lighting units 100 shown in the first embodiment, and the plurality of lighting units 100 are arranged in parallel in an array. The arrangement interval between the respective lighting units 100 is set so that the entire illuminance distribution (indicated by one dotted chain line in the figure) in which the intensity of the illumination light components from adjacent lighting units 100 is adjusted becomes flat.

[0149] According to this structure, by arranging a plurality of lighting units, the range in which the illuminance becomes uniform can be extended,...

Abstract

An illumination unit and an illumination apparatus is provided, which can provide, while saving electric energy, an illumination area with high illumination intensity and specific flat illumination intensity distribution and which can extend the distance of illumination. An illumination unit 100 using light emission diodes 17 as the light emission source. The illumination unit has a light emission section where the light emission diodes 17 are arranged on a base 19, a first reflection section 25 that is arranged on the light exit side of the light emission section so as to correspond to the individual light emission diodes 17 and that substantially parallelly reflects rays of light from the light emission diodes 17 toward the light exit side, and a second reflection section provided further on the light emission side of the first reflection section 25 and substantially parallelly reflecting, toward the light exit side, that portion of the rays of light from the light emission diodes 17 which does not enter in the first reflection section 25.

Description

technical field [0001] The present invention relates to a lighting unit using an LED as a light source and a lighting device including the lighting unit. Background technique [0002] As conventional lighting equipment, various types of lighting sources such as fluorescent lamps, incandescent lamps, and spotlights are used. However, the illuminating light from such an illuminating light source includes ultraviolet rays that damage an irradiated target, or the illuminating light source has installation restrictions due to heat generation. Considering things like CO 2 To reduce environmental concerns, it is desirable for light sources to have as little power consumption as possible. Recently, an LED light source that generates a small amount of heat and has low power consumption has attracted considerable attention, and also provides a white LED with high luminance. Therefore, the use of LED light sources in general lighting equipment is increasing. Since LED has high brig...
