Abstract

The invention provides a spectral cutting LED mosquito-repelling bulb and a manufacturing method thereof. The bulb comprises a lamp base and a bulb shell; the lamp base and the bulb shell are fixedlyconnected; a driving power supply is arranged in the lamp base; a core column is arranged on the lamp base; the core column is connected with an LED light-emitting unit; the core column and the LED light-emitting unit are arranged in the bulb shell; the lamp base, the driving power supply, the core column and the LED light-emitting unit are electrically connected in sequence; a spectral cutting layer is arranged on the inner wall of the bulb shell; the LED light-emitting unit comprises a bracket; a plurality of PCBs are arranged on the bracket in a surrounding mode; LED lamp beads are arrangedon the outer sides of the PCBs; the core column, the PCBs and the LED lamp beads are electrically connected in sequence; and the plurality of PCBs are arranged on the bracket in a surrounding way ina mode that the PCBs are not in contact in pairs. According to the bulb, the spectral cutting layer is adopted to cut blue purple spectrums loved by mosquitoes; continuous spectrums of other white light are reserved; and the bulb is high in power, has a good mosquito repelling effect, is suitable for human eye vision, can reduce the harm of blue light, is especially suitable for use at night, andis low in manufacturing cost.

Description

Technical field

[0001] The invention relates to the technical field of bulb manufacturing, in particular to a spectrum cutting LED mosquito repellent bulb and a preparation method thereof. Background technique

[0002] According to the currently known technology, mosquitoes have phototaxis (favors) for the 380-500nm part of the visible spectrum, but avoid the 500-780nm spectrum, especially the 600nm or so is more uncomfortable (disgusting). In the market, everyone uses 430nm light to attract mosquitoes with high voltage electric shock or electric fan blades for mechanical killing, or use yellow single spectrum 600-630nm LED to make low-power mosquito repellent lamps. The first product above attracts more mosquitoes to the work area. , The latter is affected by the milliwatt level of the yellow single spectrum 600-630nm LED low-power lamp bead unit chip, the power is difficult to be high and cannot keep up with the mosquitoes, or the use of more units causes high costs, and the ye...
