Light source of LED (light-emitting diode) insect killing lamp with multiple crest optical spectrums

Abstract

The invention relates to a light source of an LED (light-emitting diode) insect killing lamp with multiple crest optical spectrums, belonging to a semiconductor LED (light-emitting diode) light source and the application field thereof. The light source comprises a lamp holder, a transparent light tube and a metal heat dissipating column arranged in the transparent lamp holder; an LED (light-emitting diode) metal base printed circuit board on which a luminescent device is surface-mounted is arranged on the metal heat dissipating column; the metal heat dissipating column is a regular polygon hollow cylindrical surface body; a regular hexagon is preferably used as the cross section of the metal heat dissipating column; the spectrum range of the light source is in the range of 320-650nm; the number of the crests of the light spectrum is 6; and the crests have different luminous colors and comprise an ultraviolet LED (light-emitting diode), a blue light LED (light-emitting diode), a green light LED (light-emitting diode), a green yellow light LED (light-emitting diode), a yellow light LED (light-emitting diode) and an orange red light LED (light-emitting diode) which are different in main wavelength. The radiation efficiency is increased from 12% of a black light lamp to 20%; and therefore, the Light source has the advantages of saving the energy source consumption, being beneficial to energy saving, environmental friendliness and having low cost. The service life of the light source is prolonged to ten thousand hours; the angles of light beams are increased from 120 degrees of an LED (light-emitting diode) luminous element to 360 degrees of the LED (light-emitting diode) light source so that the whole light spectrum trapping on different types of insets at different growth stages is effectively realized.

Description

technical field [0001] The invention relates to a semiconductor LED light source, a lamp and the application field thereof, in particular to an LED light source for killing insects with multi-peak spectrum. Background technique [0002] In addition to chemical control, physical control is also an effective means of pest control in agriculture and forestry. Common physical pest control methods are divided into two categories. One type uses the unique color or taste of agricultural and forestry pests to coat colored cardboard or wooden boards with glue or engine oil to kill some small pests, commonly known as 'insect-killing swatches'; the other uses agricultural and forestry pests to Unique phototaxis, using lights to lure and kill pests, called "insect killer lamp", its effect of killing pests is far better than that of color boards. In the past 30 years, electric light sources have been used to trap pests successively. The electric light sources used in turn include incan...

AI Technical Summary

Problems solved by technology

First, the spectral range is narrow and the wave peak is single. The spectral peaks of the visually sensitive areas of pests are different. Within the spectral range marked by the vibrating light source, but there is no corresponding peak

The second is the radiation efficiency, that is, the radiation energy generated by the unit electric power is low.

The third is that with the increase of working time, the radiation power intensity decays quickly, and the maintenance characteristics of radiation intensity are not good. Fourth, the life of the light source is short, and the life of the outdoor environment is about 3000~5000 hours.

These problems not only affect the insecticidal effect, but also cause high power consumption and use costs

In addition, the traditional light source contains about 5 mg of mercury, so it is necessary to strictly prevent mercury poisoning during production, and to prevent the environment from being polluted by mercury when disposing of waste lamps
