Abstract

The invention discloses an LED ultraviolet sterilizing lamp, which comprises a connecting base, a lamp body fixedly arranged on the connecting base and a light emitting source in the lamp body, wherein the light emitting source comprises a UVC semiconductor driver board, a UVC semiconductor, a reflector, an LED driver circuit board, an LED lamp bead, a light-transmitting window and a lens; the UVC semiconductor driver board is inlaid with and connected to the connecting base; a radiating substrate is arranged on the connecting base; the wavelength of ultraviolet emitted by the UVC semiconductor is 250-270nm; the reflector is represented as a hollow round platform with upside bigger than downside and is arranged around the UVC semiconductor; lower bottom corners on two sides of the reflector form included angles of 30 degrees with the horizontal surface; ultraviolet is reflected by the reflector and is emitted by an emission angle of 120 degrees; and light of the LED lamp bead radiates the reflector, and is reflected on the lens and intensively emitted from a transparent shade. The sterilizing lamp disclosed by the invention is simple and reasonable in structural setting, relatively low in manufacturing cost, high in ultraviolet emission efficiency and long in service life of LED lamp; and the sterilizing lamp can realize controllable sterilizing angle and improve sterilizing effect.

Description

[0001] technical field [0002] The invention relates to the technical field of a medical lighting device with a sterilizing function, in particular to an LED ultraviolet sterilizing lamp. [0003] Background technique [0004] Ultraviolet light sterilization is to use cells to have the greatest absorption of ultraviolet rays with a wavelength of 250-270nm. The absorbed ultraviolet rays act on the genetic material (deoxyribonucleic acid, DNA) of cells, which acts as a photochemical effect. The energy of ultraviolet photons is absorbed The base pairs in DNA are absorbed, causing genetic material to mutate, causing the bacteria to die immediately or unable to reproduce offspring, thus achieving the purpose of sterilization. [0005] The usual ultraviolet germicidal lamp is actually a kind of low-pressure mercury lamp, which, like ordinary fluorescent lamps, is excited by the lower mercury vapor pressure to emit ultraviolet rays. The difference is that the lamp tube of the fl...
