In order to reduce the volume of the headlight, the xenon bulb and the LED are usually placed on the same side of the headlight. At this time, the LED passes through the through hole of the reflector cup of the xenon lamp, which greatly reduces the reflective surface of the reflector cup, thereby reducing the reflection efficiency
In addition, because the headlight controls the lighting through the button switch, sometimes it needs multiple operations to achieve the desired state, and the button switch is not easy to find in the dark, and the user usually wears gloves and other labor protection products, which increases the Difficulty of operation

Embodiment Construction
[0019] Referring to Fig. 1, Fig. 1 shows a sectional view of a specific embodiment of the headlight of the present invention. The headlight 100 includes a housing 1 , lighting units accommodated in the housing 1 (respectively, a high light 2 and an energy-saving lamp 3 in this embodiment), and a support shaft 40 supporting the housing 1 .
[0020] The casing 1 includes: a casing body 10 on the upper part for accommodating the high light 2 and the energy-saving lamp 3 ; The casing body 10 has openings 101 , 102 at both ends respectively, and the openings 101 , 102 are closed by transparent baffles 111 , 121 . The strong light lamp 2 and the energy-saving lamp 3 are accommodated on opposite sides of the housing body 10 , so that the light emitted by the strong light lamp 2 and the energy-saving lamp 3 can be emitted through the transparent baffles 111 , 121 .
[0021] In order to maintain the airtightness of the casing 1 on both sides, side end covers 11 , 12 are covered outsid...

Abstract
The invention discloses a headlight which includes the shell, at least one illumination unit set in the shell and the supporting axis to support the shell. The shell can rotate when it is supported on the supporting axis to control the open and close of at least one illumination unit by shell rotating related to the axis. By turning the shell, it can change the illuminating mode. So it is proper for the wild night work especially for the mine and diving.
Description
technical field [0001] The invention relates to a lighting device, in particular to a headlight. Background technique [0002] The headlight is generally fixed on the head for personal use for lighting, especially suitable for mines and field night operations. At present, the light sources used in headlights include incandescent lamps, krypton lamps, xenon lamps, light-emitting diodes (LEDs), halogen lamps, high-power LEDs, xenon gas discharge lamps, etc. The power sources used in headlights are also various, including dry batteries. , Ni-MH (nickel-cadmium) batteries, lithium batteries, lead batteries, fuel cells. The lighting methods are also different. There are close-range lighting, generally within 1m, usually using energy-saving lamps for lighting, such as LED; medium and long-distance lighting, generally within 1m to 50m, usually using strong lights for lighting, such as high-power LEDs, xenon lamps, etc. , because the power consumption of strong light and energy-sa...
