Abstract

The invention discloses a near ultraviolet LED mosquito repelling lamp. The lamp is composed of a bulb shell (1), a fluorescent powder layer (2), a radiator (3), an insulation piece (4), a near ultraviolet LED light source (5), a base plate (6), a lamp holder (7) and a driver (8). The near ultraviolet LED is adopted for exciting Ma(TiO3)b(Si2O5):Mnc and Eud fluorescent powder, the bulb shell capable of filtering light with the wavelength smaller than 400 nanometers, the wavelength of light emitted by the LED mosquito repelling lamp is concentrated within 550-700 nanometers, and the purpose ofmosquito repelling is achieved; the bulb shell is coated with fluorescent powder, the phenomenon that performance deterioration of epoxy resin and silica gel and other packaging materials appear underthe near ultraviolet light with the wavelength being 400 nanometers or smaller is avoided, the performance is much better than a common incandescent light bulb, a fluorescent lamp mosquito repellinglamp and a blue-light-excited LED mosquito repelling lamp, energy is greatly saved, environment pollution is reduced, and the light biological damage caused by long-term high-strength blue light irradiation is avoided.

Description

technical field [0001] The invention relates to an illumination light source, in particular to a near-ultraviolet LED mosquito repellent lamp and a preparation method thereof. Background technique [0002] LED (Light Emitting Diode), a light-emitting diode is a semiconductor device that directly converts electrons into photons through a PN junction. It does not require a thermal process and belongs to direct light emission. Different semiconductor materials emit different wavelengths due to their different forbidden band widths. LED has the characteristics of energy saving, environmental protection and long life. The luminous efficiency of LED can reach more than 140lm / W at high power, and more than 130lm / W at low power, far exceeding the level of incandescent lamps and fluorescent lamps. / W; The theoretical life of the LED light source can reach 100,000 hours, and the current general LED life is 35,000 to 50,000 hours. The lifespan of incandescent lamps is generally 1000...
