Title:
LAMP
Document Type and Number:
Japanese Patent JP2016006774
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To enable a fluorescent lamp or various versatile lighting lamps replaced with usual lighting units, for example, to be used simply without any glaring or at least with quite reduced glaring.SOLUTION: A lamp 1 has a plurality of LEDs 2 arranged in vertical orientation in a longitudinal direction of the lamp 1 by using an LED carrier 5 while being spaced apart of the LEDs 2. Each of the LEDs 2 emits light in a specified solid angle area around a central direction 7 of a light beam. The solid angle area is faced toward a lamp reflection plate 8 for use in indirect emission of light from the lamp 1. The number of LEDs 2 and/or the spacing of the LEDs 2 are selected in such a way that they are at least 0.2 to 2.5 times of a distance between the LEDs 2 where the solid angular areas of all the LEDs 2 are positioned in most spaced apart relation and at a lighting surface distance from the bottom surface of the lamp 1 so as to be at least partially overlapped after reflection at a light reflection plate.
