Abstract

The invention discloses a handheld type multifunctional LED (Light Emitting Diode) mining lamp, and relates to the field of LED illumination. The handheld type multifunctional LED lamp comprises a lamp shell, wherein the inner part of the front end of the lamp shell is provided with a high-power LED light source, the LED light source is connected with a constant-current power supply, the consistent-current power supply is arranged at the inner part of the lamp shell, the rear end of the lamp shell is provided with a rearview light source, the rearview light source is connected with the consistent-current power supply, the outer side, which is close to one end of the rearview light source, of the lamp shell is provided with annular LED colorful lamps, the lamp shell is also provided with an alarm horn, the alarm horn is positioned at one side of the LED colorful lamps, and the LED colorful lamps and the alarm horn are connected with a switch. According to the handheld type multifunctional LED lamp disclosed by the invention, by also arranging the rearview light source at the rear end of the lamp shell, a rear place can be conveniently illuminated by people, and the operation is convenient; when miners suffer from a dangerous situation and alarming needs to be carried out, the control switch of the annular LED colorful lamps and the alarm horn can be switched on, the alarm horn can emit sound, reminding light can be emitted, and assistance can be provided for salvagers to quickly find the miners suffering from danger.

Description

technical field [0001] The invention relates to the field of LED lighting, in particular to a hand-held multifunctional LED miner's lamp. Background technique [0002] With the rapid development of semiconductor light-emitting diodes, LED lighting is now in a stage of rapid development, and its outstanding performance advantages have made it a shining symbol of the information age. The energy waste of factory lamps (such as incandescent lamps) in general lighting technology is very serious. In today's low-carbon and energy-saving environment, the development of new lighting technologies has become an imperative trend. The main advantages of LED lighting are long life, low power consumption, no radiation, no pollution, etc. Therefore, in the development of technology, how to design LED lighting lamps with longer life and lower power consumption is the main technical problem to be solved. Most of the existing industrial and mining lamps are high-pressure sodium lamps and met...

Problems solved by technology

Most of the existing industrial and mining lamps are high-pressure sodium lamps and metal halide lamps. Although they have certain advantages in terms of energy saving and environmental protection compared with ordinary lighting lamps, they are far from meeting the factory's requirements for low energy consumption. Therefore, looking for a A lighting technology with lower energy consumption and longer life can save a lot of cost for the factory. The application number is CN 03209222.9, which discloses a light energy-saving miner's lamp, which consists of a lamp holder, a switch, a battery, a clip, a flameproof shell, and a charging terminal. , constant current matching circuit, and dust cover; the white light semiconductor light-emitting diode installed in the lamp head is powered by a solid-state rechargeable battery, and the constant current matching circuit is constant voltage and constant current, so that the lamp head, battery, and switch are combined into one, with a compact , light, long life, safety, reliability, environmental protection and other characteristics, it is used for helmet lights, used in various flammable and explosive places, but this kind of miner's lights can only illuminate in one direction, you need to observe the situation behind When the miners are in danger, the lamp head must be turned over, especially in some places with narrow spaces, it is very inconvenient to use, and when the miners are in danger and need to call for help, there is no alarm and prompting device
