Description

The present invention relates to a new family of electronic lamps having conventional shapes but whose light source is based on light emitting diodes (LEDs). Current lamps traditionally generate a relatively low level of illumination. The sources of some LED lamps have a positioning of their light source flat with a luminous flux that goes in the direction of the lamp from the base to the transparent envelope. This spatial orientation does not provide sufficient illumination level results and today, there is no simple and effective way to provide illumination with such features. The present invention aims to propose a solution to this problem. To this end, the present invention provides a lighting lamp, whose generating source is composed of light emitting diodes (LEDs). According to the invention, the assembly of the elements of this source makes it possible, thanks to a spatial positioning, to cone to put a higher number of LEDs on the same support, thus increasing the gain of the luminous flux in the same direction, compared to the others. similar lamps having fewer elements, which allows this lamp to obtain brightness characteristics higher than the market while being energy efficient and long-lasting. According to particular embodiments: The positioning of the elements of this source on the electronic light generator allows, thanks to a spatial positioning, in a cone, to put a higher number of LEDs on the same support, thus increasing the gain of the flux bright in the same direction. The physical situation of the LEDs is distributed with a concentric geometric position. The physical orientation of the LED heads has an angle of inclination, defined according to the emission angle of the luminous flux of the LEDs, this emission angle being of any value.
