Abstract

The utility model discloses an electric bicycle LED headlamp belongs to LED illumination field, which comprises an upper housing, upward be equipped with the radiator above the casing, be equipped with the heat-conducting plate below the radiator, the casing front end is equipped with optical lens or the anti-light cup of optics, be equipped with the LED light source on optical lens or the anti-light cup focus of optics, its light source constitutes the heat conduction with aluminium base board and heat-conducting plate and is connected, the LED during operation sends the heat, give the heat-conducting plate through aluminium base board conduction, because heat-conducting plate design thickness 2.5-4 millimeters, can carry out ventilation cooling on the heat conduction that LED produced gives the outside radiator fin of car light casing with the high efficiency. Be equipped with bayonet socket and draw-in groove on the lower casing of car light, aluminium base board and heat-conducting plate are all by firmly blocking, and its sound construction is reliable, because the radiator is established at the surface of casing, more is favorable to ventilation cooling when the vehicle goes, can in time dissipate the heat that the LED during operation produced fast, has solved the problem that generates heat and lead to the light decay in the LED use.

Description

LED headlamp of electric bicycle

The technical field is as follows:

the utility model belongs to the LED illumination field relates to an electric bicycle LED headlamp.

Background art:

despite twenty years of development history, the electric bicycle still has two major problems in the aspect of high-power LED car light illumination, namely insufficient brightness, serious light attenuation and short service life. The main reason is that the heat dissipation problem of the LED car lamp is not solved, so that the heat generated by the LED car lamp in use cannot be dissipated and accumulated on a PN junction of the LED car lamp, and the consequences of light attenuation and lamp death of the LED car lamp are caused. The market also has an electric bicycle lamp, adopts totally enclosed design method, is to design the radiator in the confined casing, and the temperature sharply increases in the short time shell, and another condition LED and radiator contact surface are not abundant enough, cause the thermal resistance, and these two kinds of condition all do not do benefit to LED's heat and distribute, and influence luminance and life-span, directly influence people's safety trip night.

The invention content is as follows:

the utility model aims at providing an electric bicycle LED headlamp, it can solve current car light because of the heat dissipation problem is handled improperly, and causes the defect that LED can not normally work for a long time to solve LED and produced the problem of light decay because of using in the heat, be fit for being applied to various electric bicycle, tricycle, motorcycle.

The utility model discloses a realize through following technical scheme, electric bicycle LED headlamp includes casing and lower casing, upward be equipped with the radiator above the casing, be equipped with radiating fin above the radiator, upward the casing designs aluminium matter structure as an organic whole with the radiator, be equipped with the heat-conducting plate below the radiator, preceding aluminium base board and the high-power LED of being equipped with of heat-conducting plate, the heat-conducting plate lower extreme is equipped with the screw hole, be equipped with the bayonet socket respectively above the casing down, draw-in groove and screw hole, for fixed aluminium base board, the connection of heat-conducting plate and lower casing, be equipped with two screws above aluminium base board and the heat-conducting plate, it fixes the heat conduction with the screw during it, preceding optical lens or the optics cup that is equipped with of aluminium base board reflects light, the heat-conducting plate is equipped with buzzing piece loudspeaker and goes out the sound hole at the back.

For further realizing the purpose of the utility model, the following technical proposal is adopted: the LED headlamp of the electric bicycle is characterized in that a radiator is arranged on an upper shell of the LED headlamp of the electric bicycle, a heat conducting plate below the radiator penetrates through the upper shell, a screw hole is formed between the upper shell and the radiator and fixedly connected with the upper shell through a screw, and a buzzer horn is arranged on a lower shell; the lower shell of the LED headlamp of the electric bicycle and the radiator are of an integrated aluminum structure, a heat conducting plate is arranged on the aluminum lower shell, an aluminum substrate is arranged in front of the heat conducting plate, a high-power LED is arranged in front of the aluminum substrate, and the aluminum substrate and the heat conducting plate are provided with two screws which are fastened for heat conduction; the double-screw bolt is arranged between the upper shell and the lower shell of the automobile lamp, so that the double-screw bolt can be assembled and used, the front end and the rear end of the upper shell and the rear end of the lower shell of the automobile lamp are provided with clamping grooves, and the optical lens or the optical reflection cup and the buzzer horn are clamped and fixed by the clamping grooves during assembly.

The beneficial effects of the utility model reside in that: the high-power LED is used as a headlamp light source of the electric bicycle and used as a solid light source, and the high-power LED headlamp light source has the advantages of simple structure, stability, reliability, safety and convenience in use, high photoelectric conversion efficiency, energy conservation, power saving and long service life.

Description of the drawings:

FIG. 1 is a schematic structural diagram of the present invention;

the LED lamp comprises a radiator 1, an upper shell 2, a bayonet 3, a heat conducting plate 4, an aluminum substrate 5, a high-power LED 6, a buzzer horn 7, a sound outlet hole 8, a bayonet 9, a clamping groove 10, a screw hole 11, a screw 12, a support hole 13, a lens or a reflecting cup 14, a lower shell 15 and a fin 16

The specific implementation mode is as follows:

FIG. 1 shows: scheme one, electric bicycle LED headlamp, including upper casing 2 and radiator 1, the radiator 1 of the two aluminium matter structures as an organic whole, be equipped with heat-conducting plate 4 below the radiator 1, its thickness is 2.5-4mm, aluminium base board 5 in front of heat-conducting plate 4 is equipped with the screw, fasten with two screws therebetween, do benefit to heat-conduction, insert the bayonet socket 9 and the draw-in groove 10 that set up above lower casing 15 with the heat-conducting plate lower extreme during assembly, place lens or reflection of light cup 14 and buzzer loudspeaker 7 respectively in the draw-in groove of the front and back end of car light casing, the heat-conducting plate is connected fixedly through screw hole 11 by screw 12, upper and lower casing passes through screw fixed mounting by the double-screw bolt that sets up between the upper and lower casing. Scheme two, when needing that the radiator heat radiating area is less, can set up radiator 1 on upper casing 2, heat-conducting plate 4 passes upper casing 2, and heat-conducting plate 4 is fixed on upper casing 2 with the screw, can cancel bayonet socket 9, draw-in groove 10 on lower casing 15 at this moment, and buzzing piece loudspeaker 7 can set up on lower casing 15. The third scheme is an aluminum structure integrating the lower shell 15 of the LED headlamp of the electric bicycle and a radiator, namely the lower shell 15 is made of aluminum, the heat conducting plate 4, the aluminum substrate 5 and the high-power LED 6 are arranged on the upper surface of the lower shell 15, and other technical schemes are the same as those of the third scheme.

The known art of this product is not described in detail.
