Abstract

PURPOSE:To relatively easily obtain various irradiation light distributions by providing the first reflector transmitting part of the light and reflecting the remainder at the middle section of a lamp body, and providing the second reflector reflecting the lamp permeating the first reflector at the upper section of the light body. CONSTITUTION:The light from a luminous section 2 is partially reflected by the first reflector 5 and radiated from the side face. The light permeating the first reflector 5 is reflected by the second reflector 6 and likewise radiated from the side face. When respective irradiation light distributions are changed in the first and second reflectors, various overall irradiation light distributions are obtained. If each reflector has two kinds of irradiation light distributions, for example, four kinds of overall irradiation light distributions are obtained. The first reflector 5 reflecting part of the light and passing the remainder is used, thus various irradiation light distributions are obtained via the vertically located first and second reflectors.

The light emitting unit 2 emits light upward, and includes a light source 3 such as a light bulb or a high-intensity discharge lamp, and a reflecting mirror 4. In the case of a road light or a garden light, the light emitting section 2 may be buried underground. Reference numeral 5 denotes a first reflector, which is disposed in the middle of the lamp body 1. The first reflector 5 transmits a part of the light from the light emitting section 2 and reflects the rest to irradiate the light from the side surface of the lamp body 1 . Further, the first reflector 5 is capable of changing the irradiation light distribution. That is, in this embodiment, the first reflector 5 is made of punched metal with a mirror finish on both sides, and is formed into a hemispherical surface. Therefore, the irradiation light distribution is different depending on whether the convex side of the first reflector 5 faces the light emitting section 2 or the case where the concave side of the first reflector 5 faces the light emitting section 2. The structure for locking the first reflection #-5 to the lamp body 1 is not shown in the drawings, but means such as providing a locking step on the inner wall of the lamp body 1 may be used as appropriate. Note that by forming the first reflector 5 from a thin material, the first reflector 5 is deformed, that is, made into a convex state or a concave state when viewed from one side, thereby changing the irradiation light distribution. You can do it like this. 6 is a second reflector. This second reflector can also be configured in the same manner as the first reflector 5.
