LED lighting device capable of adjusting irradiation range for field travel

Abstract

The invention relates to the technical field of LED lamps, and discloses an LED lighting device capable of adjusting an irradiation range for field travel, which comprises a main shell, a sleeve is inserted into the left side of the main shell; the left side of the sleeve is fixedly connected with an LED lamp; a first fixed block is fixedly connected to the outer part of the sleeve; a plurality ofgrooves are formed in the outer portion of the sleeve, a fixing ring is arranged in the main shell, four straight grooves are formed in the fixing ring, third springs are fixedly connected to the sides, opposite to each other, of the four straight grooves, and clamping blocks are fixedly connected to the opposite sides of the four third springs. When the sleeve is static, the third spring extrudes a clamping block to the position away from a straight groove, the clamping block is inserted into the groove, the sleeve is fixed, then the LED lamp is fixed, and therefore the effects that when a user moves, the lighting device is rapidly shaken, the sleeve can drive the LED lamp to slide, the lighting range is changed, and inconvenience is brought to the user are achieved.

Description

technical field [0001] The invention relates to the technical field of LED lamps, in particular to an LED lighting device for outdoor travel that can adjust the irradiation range. Background technique [0002] LED light is an electroluminescent semiconductor material chip, which is generally cured on the bracket with silver glue or white glue, and then connected to the chip and circuit board with silver or gold wires, and sealed with epoxy resin around. With the development, LED lamp technology is becoming more and more perfect, and it is widely used in the lighting industry. [0003] Generally, LED lighting devices are necessary for outdoor travel and exploration. At present, the lighting devices on the market usually directly change the light intensity when adjusting the irradiation distance and range, which is likely to cause insufficient light intensity when irradiating at close range, and the use is limited. Therefore, we propose a LED lighting device for outdoor trave...

AI Technical Summary

Problems solved by technology

[0005] Aiming at the deficiencies of the prior art, the present invention provides an LED lighting device for field trips that can adjust the irradiation range, which has the advantages of being able to adjust the irradiation range and not change the light intensity when used in the field, and solves the current problem in the market. When the lighting device adjusts the irradiation distance and range, it generally directly changes the intensity of the light, which is likely to cause insufficient light intensity when irradiating at close range, and the problem of large use limitations
