When the first functional module 43 is selected to operate through the button 41, the light emitting assembly 3 has five light emitting modes, which are a high light mode, a middle light mode, a low light mode, a night flashing mode and a day flashing mode, respectively, and is suitable for meeting all basic requirements of users. When the second functional module 43 is selected to work through the button 41, the light-emitting assembly 3 has three light-emitting modes, namely a high-light mode, a medium-light mode and a low-light mode, and is suitable for a user to use on a road with complex lighting conditions and a relatively expanded view; specifically, different brightness modes are required to be frequently switched on the road, flashing light is not required to remind a driver and pedestrians, and conversely, if flashing light occurs in the frequent switching process, the eyes of the user are easily damaged or blinded for a short time; therefore, under the second functional module 43, the night flashing mode and the day flashing mode are removed, so that the user can quickly select different brightness for use on such roads through the button 41, and the flashing does not occur during the selection process, which is beneficial to protecting the eyes of the user. When the third functional module 43 is selected to work through the button 41, the light-emitting assembly 3 has two light-emitting modes, namely a high-light mode and a low-light mode, and is suitable for a user to use on a road with sudden and dim illumination and a relatively expanded view; specifically, the high brightness mode and the low brightness mode are frequently selected and used on the road, the significance of the high brightness mode is not great during use, and flashing light is not needed to remind drivers and pedestrians; therefore, under the third functional module 43, the middle bright mode, the night flashing mode, and the day flashing mode are removed, so that the user can select the high bright mode or the low bright mode for use by the button 41 quickly on such a road. When the fourth functional module 43 is selected to operate through the button 41, the light-emitting assembly 3 has two modes, namely a highlight mode and a night flashing mode, and is suitable for a user to use on a road with poor lighting condition and unexplored view; specifically, the road needs to keep the high brightness mode to work continuously, when the road passes through a road section such as a curve, a low-lying road, an arch bridge and the like, the night flashing mode is switched to remind an opposite driver and pedestrians, the high brightness mode and the low brightness mode are not used generally, and the daytime flashing mode is not used due to the shielding of the visual field in the daytime; therefore, under the fourth functional module 43, the middle bright mode, the low bright mode and the daytime flashing mode are removed, so that the user can select the highlight mode or the night flashing mode for use on such roads quickly through the button 41. When the fifth functional module 43 is selected to operate through the button 41, the light emitting assembly 3 has two modes, namely a daytime flashing mode and a nighttime flashing mode, and is suitable for users to use on roads with good lighting conditions and more vehicles and pedestrians; specifically, on such roads, no lighting is generally required, but a flashing light is required to alert drivers and pedestrians; therefore, under the fifth functional module 43, the high brightness mode, the middle brightness mode and the low brightness mode for providing illumination are removed, and the night flashing mode and the day flashing mode for reminding are reserved, so that the user can select the night flashing mode and the day flashing mode for use on such roads through the button 41 quickly.

The five indicator lights 44 respectively correspond to the five light-emitting modes, so that when the LED lamp is used in different light-emitting modes, the indicator light 44 corresponding to the LED lamp is turned on or flickers to remind a user of the light-emitting mode currently used; for example, when the light emitting assembly 3 operates in the highlight mode, one of the indicator lights 44 corresponding to the highlight mode is turned on or blinks. In addition, when a different functional module 43 is selected by the button 41, the indicator lights 44 corresponding to at least two light emitting modes corresponding to the functional module 43 are all turned on or all flash to remind the user that the functional module 43 has at least two corresponding light emitting modes; for example, when the fifth function module 43 is selected through the button 41, two indicator lamps 44 corresponding to the night flashing mode and the day flashing mode are turned on or flash.

The present application is not limited to the manner of selecting the function module 43 by the button 41, and examples of the method include: as shown in fig. 11, after the button 41 is pressed for a long time for five seconds, the module selection function is entered; the first functional module 43 is automatically entered, the headlights are turned off, and the five indicator lights 44 corresponding to the five lighting modes are fully turned on; after five seconds, the second functional module 43 is automatically entered, and when the headlights are turned on for two, the three indicator lights 44 corresponding to the high brightness mode, the medium brightness mode and the low brightness mode are turned on; after five seconds, the third functional module 43 is automatically entered, and when the headlamp flashes to the third state, the two indicator lamps 44 corresponding to the high brightness mode and the low brightness mode are turned on; and so on. After entering the corresponding functional module 43, pressing the button 41 once can select the functional module 43 to work; for example, when the third function module 43 is selected to operate, the third function module 43 can be selected to operate only by pressing the button 41 once after the state of the third function module 43 is automatically entered and before the fourth function module 43 is automatically entered.

As shown in fig. 10, the receiving groove 322 can receive the lamp bead 31 to prevent light emitted from the lamp bead 31 from overflowing to the outside of the cone-shaped structure 321; under the effect of the conical structure 321, light emitted by the lamp bead 31 can generate total reflection on the conical surface of the conical structure 321 and finally converge to the middle part of the lens 32, so that the generated light spot is not simple circular, but is bright in the middle and large in the periphery.

Referring to fig. 4 and 10, in some embodiments of the present application, the housing 1 further includes an end cap 14, the end cap 14 is clamped to the front cover 11, and the end cap 14 is used for covering a gap between the lens 32 and the front cover 11. The gap between the lens 32 and the front cover 11 is covered by the end cover 14, which is more beautiful.

The foregoing has described the general principles, essential features, and advantages of the application. It will be understood by those skilled in the art that the present application is not limited to the embodiments described above, which are merely illustrative of the principles of the application, but that various changes and modifications may be made without departing from the spirit and scope of the application, and these changes and modifications are intended to be within the scope of the application as claimed. The scope of protection claimed by this application is defined by the following claims and their equivalents.
