FIELD: electricity.SUBSTANCE: invention relates to lighting engineering. The lamp has multiple light-emitting diodes which are located one after another in the longitudinal direction of the lamp and with a step between light-emitting diodes, provided by means of the holder of light-emitting diodes. Each light-emitting diode radiates light into a certain area of space angle around the central beam direction. The space angle area faces towards the lamp reflector to ensure indirect radiation of the lamp light. The quantity of light-emitting diodes and/or a step between light-emitting diodes are selected in such a way that areas of space angles of all light-emitting diodes after reflection from the light reflector are blocked, at least, partially, at lighting surface distance from the lower side of the lamp, equal at least to 0.2 - 2.5 of the distance between the light-emitting diodes which are located most far everything from each other.EFFECT: technical result is prevention of formation of the blackouts and patches of light occurring during the work of light-emitting diodes.19 cl, 3 dwg |
