LED LAMP Russian patent published in 2017 - IPC F21S4/00 

FIELD: lighting.

SUBSTANCE: third contact 6 and fourth contact 7 are brought into contact with mating contacts of the external electric circuit, for example, by screwing the cap 5 into the female socket. The power supply unit 8 converts the voltage of the external electric source into an operating voltage required for the correct operation of the assembly 10. One or more light-emitting diodes 13 disposed on the substrate 15, when the current, supplied via the current-conducting string 16, flows through them, create optical radiation. The fluophoric layer converts this radiation of the light-emitting diodes 13 into the optical radiation with a modified spectrum, more favourable for human eyes. Different inclination of assemblies 10 relative to the bulb 1 axis, as well as their relative location allow, depending on the product design, to place the lighting spatial angle axis from each individual assembly 10 so that the general direction pattern of light radiation was the closest to the spherical shape.

EFFECT: increase in the uniformity of the direction pattern of the light radiation.
