Weeding lamp with LED light source

Abstract

The invention discloses a weeding lamp with an LED light source and belongs to the technical field of weeding lamps. The weeding lamp comprises a power amplifying assembly, a connecting rod and a griping assembly, wherein a head end of the connecting rod is fixedly connected with the power amplifying assembly, a tail end of the connecting rod is fixedly connected with the griping assembly, a heatradiator is arranged on the internal wall of the head end of the connecting rod, the power amplifying assembly comprises the LED light source and a heater, the LED light source is arranged on the heatradiator, and the heater is fixed onto a shell body and is close to the LED light source. A working principle is as follows: a certain high temperature achieved by the heater is transferred to surfaces of weeds through glass, thus, leaves of the weeds die, and appointed weeds are continuously subjected to secondary destruction by using regeneration destroying capacity characteristic of blue light. Lateral plants cannot be damaged due to single-point clearing, and the problem that chemical residual is caused due to usage of pesticides or by using tools, only surface weeds are pruned, grass roots are still in soil, and the weeds will repeatedly grow in a period of time can be avoided.

Description

technical field [0001] The invention belongs to the technical field of weeding lamps, and in particular relates to an LED light source weeding lamp. Background technique [0002] At present, artificial chemical weeding is widely used for weeding, but with people's attention to food safety, the method of spraying chemical herbicides is gradually replaced by mechanical weeding, and has achieved certain results. However, mechanical weeding There are the following problems: due to the limitation of mechanical weeding control precision, it is easy to cause mechanical damage to crop seedlings, resulting in a high damage rate of crop seedlings; due to different row spacing and different cultivation methods of different crop seedlings, the size of the mechanical device is strictly limited ;Mechanical weeding preserves the seeds of weeds, which will lead to the re-germination of weeds. [0003] To sum up, in order to solve the lack of functions of the weeding lamp, it is necessary t...
