LED head lamp with adjustable illumination angle based on double lamp caps

Abstract

The invention discloses an LED head lamp with an adjustable illumination angle based on double lamp caps. The LED head lamp comprises an arc-shaped head hoop, first rotating seats are fixedly connected to the side surfaces of two ends of the arc-shaped head hoop; first rotating grooves are formed in sides, far away from the arc-shaped head hoop, of the first rotating seats; the bottoms of the inner walls of the first rotating grooves are fixedly connected with spring sets; the ends, away from the bottoms of the inner walls of the first rotating grooves, of the spring sets are fixedly connectedwith first top plates. First damping pads are fixedly connected to the sides, away from the spring sets, of the first top plates, second damping pads are slidably connected to the sides, away from the first top plates, of the first damping pads, and second top plates are fixedly connected to the sides, away from the first damping pads, of the second damping pads. The invention relates to the technical field of LED illumination lamps. The LED head lamp capable of adjusting the illumination angle based on the double lamp caps is good in adjusting effect, can illuminate in different directions,and can clean a glass plate at the front section of an illumination lamp during use, so that the illumination effect is prevented from being influenced by shielding of foreign matters.

Description

technical field [0001] The invention relates to the technical field of LED lighting lamps, in particular to an LED headlight with adjustable irradiation angle based on double lamp heads. Background technique [0002] Light-emitting diodes are referred to as LEDs for short. When electrons and holes recombine, they can radiate visible light, so they can be used to make light-emitting diodes. As an indicator light in circuits and instruments, or as a text or digital display, gallium arsenide diodes emit red light, gallium phosphide diodes emit green light, silicon carbide diodes emit yellow light, and gallium nitride diodes emit blue light. Divided into organic light-emitting diode OLED and inorganic light-emitting diode LED. [0003] According to Chinese patent CN103322422A, it includes a headlight belt, and also includes a power supply device and a lighting device. The power supply device is arranged on the headlight belt, and the power supply device is connected to the ligh...

AI Technical Summary

Problems solved by technology

[0007] Aiming at the deficiencies in the prior art, the present invention provides an LED headlight with adjustable irradiation angle based on double lamp heads, which solves the problem that the LED headlight usually adjusts the irradiation direction according to the twisting of people's head, but the twisting of the head The range is limited, but the field of view is large. The headlight simply bound to the forehead cannot meet the needs of the field of vision, and cannot be adjusted to illuminate on both sides. In addition, when the weather is hot, the straps bound to the head are prone to suffocation. Storage The glass plate in front of the headlight is easily damaged by other objects
