LIGHT-EMITTING MODULE, LIGHTING LAMP AND STREET LIGHT

摘要

PROBLEM TO BE SOLVED: To solve a problem that a brightness just above LEDs becomes high and glaring may occur in the case of constitution of globe by transparent material as well as in the case of constitution of dispersed transparent material in view of a lighting lamp having a light-emitting part using LEDs and showing distribution of light expanding over an entire circumference and LEDs arranged oppositely against and near the inner surface of a globe (an outer tube valve) and light radiated from LEDs passing through the globe and showing outgoing radiation.SOLUTION: Adjoining substrates of a plurality of substrates having LEDs practically mounted are held to show a central angle less than 90 degrees, LEDs at the substrates are arranged at positions where light radiates toward a front plane of each of LEDs is shielded by the substrate arranged at a front side of the LEDs so as to reduce the maximum brightness while the light showing high brightness toward the front plane is not directly outputted to the outside of a lighting lamp and restrict its glaring.SELECTED DRAWING: Figure 1
