Title: LED LAMP
Abstract:
The invention relates to lighting technology, and specifically to energy-saving lighting devices created on the foundation of powerful LEDs having a long service life. The invention may be used for creating illumination devices not having a blinding effect, for spaces such as residential rooms, office spaces, car approach areas outside of buildings, and also for illuminating streets and highways. The technical result consists in eliminating the blinding effect of LEDs and providing for uniform illumination. An LED lamp contains a housing, LEDs, a diffusion cover, and reflective plates, which reflective plates are installed in a way that at least a portion of the reflective plates have surfaces which face the LEDs and which are not shielded from LED radiation by reflective plates (not otherwise obscured by the reflective plates) which are located closer to the LEDs in the direction of propagation of a light flux from the LEDs. The LEDs are installed on a circuit board which is perpendicular to the front plane of the projection of the housing and which is inclined toward the diffusion cover, wherein the central rays of the LEDs are directed at a front reflecting plate. The front reflecting plate is installed between the reflective plates and the housing, and has an arc-shaped reflective profile. The reflective plates are in the form of plates having curved reflective surfaces. The reflective plates have varying cross-sectional thickness. The reflective plates abut the diffusion cover. The reflective plates and the diffusion cover are carried out as a single component. The invention contains an end reflecting plate and a front reflecting plate, which are carried out as a single component. An external device is used for power supply.
