Description
Technical field
The utility model relates to a kind of lighting device on bicycle.
Background technology
Illumination equipment in the bicycle is to drive the triboelectricity machine with wheel to rotate generating (being commonly called as the mill motor), and generator speed changes with vehicle wheel rotational speed speed ratio, and the voltage that electrical generator sends, electric current are with rotation speed change.Headlight, taillight provide illumination (headlight) by generator powered, safety indication (taillight).
Headlight in the standard bicycle dynamo-powered lamp, taillight use filament bulb as light source (headlight 6V2.4W, taillight 6V0.6W).Filament bulb exists that power hungry is big, the life-span short (national standard 60 hours), and shock-sensitive shortcoming such as moving is used in and brings the trouble that frequently more changes the bulb on the bicycle.
The utility model content
Adopt the shortcoming that filament bulb is big as the power consumption that light source exists, the life-span is short at prior art, and according to the handling characteristics of bicycle, the inventor has developed the lighting device on bicycle of a kind of LED of utilization bulb as light source.
For achieving the above object, a kind of lighting device on bicycle of the utility model comprises headlight, and this headlight comprises shell, the shell front portion has lampshade, be provided with installation seat plate in the shell, at least one LED bulb is installed on the installation seat plate, LED bulb rear side is provided with prefocus cup.
Further, described installation seat plate is provided with several LED bulbs that is cellular distribution.
Further, described each LED bulb rear side that is cellular distribution is provided with an associated prefocus cup.
Further, described lampshade is provided with and the light beam that described LED bulb sends can be compressed into the beam split eyeglass that penetrates after the flats.
Further, some the faceted pebbles of described beam split eyeglass on lampshade, directly making.
Further, also be provided with the luminous regulator rectifier circuit of driving LED bulb in the described headlight shell, this regulator rectifier circuit directly is laid on the described installation seat plate.
A kind of lighting device on bicycle comprises Rear lamp for vehicle, and this Rear lamp for vehicle comprises shell, and the shell front portion has lampshade, is provided with installation seat plate in the shell, and at least one LED bulb is installed on the installation seat plate, and LED bulb rear side is provided with reflector.
The utility model lighting device on bicycle compared with prior art has following advantage:
1. low speed can throw light in the cycling, does not burn bubble at a high speed
Bulb can be lighted when LED headlight, tail-light were carried out at bicycle, reach illumination and safe indicating effect, and filament bulb could not.When bicycle flat-out acceleration (as descending), filament bulb may burn out filament because of the unexpected rising of voltage, and LED bulb powered circuit has the voltage-limiting protection function, can not burn bubble.
2. long service life
The life-span of filament bulb is 60 hours, and the life-span of LED bulb is 5000-10000 hour.Will change a plurality of bulbs in 1 year with the white heat bubble, and the LED bulb can use 5-10.
3. vibration resistance
Filament bulb is dashed forward when lighting and is met sharp pounding (cycling is inevitable) with very thin tungsten filament, and filament may rupture, and lose illumination or safe indicative function, and the LED bulb is not afraid of vibrations, protection bicyclist's safety.
4. save money, economize trouble
The cost of a plurality of LED bulbs is slightly higher than the cost of filament bulb though a whole set of LED wiring board adds, and be 50-100 times of filament bulb the service life of LED bulb, and the customer can not change the bulb for many years, saves many troubles.

The specific embodiment
As Fig. 1-shown in Figure 4, headlight in the utility model lighting device on bicycle comprises shell 1, and shell 1 front portion has lampshade 2, is provided with installation seat plate 5 in the shell 1, four LED bulbs 4 that are cellular distribution are installed on the installation seat plate 5, and each LED bulb 4 rear side is provided with a prefocus cup 3.Be processed with some faceted pebbles 21 on the lampshade 2, these some faceted pebbles 21 form the beam splitter structure on lampshade 2, penetrate after the beam splitter structure that constitutes by some faceted pebbles 21 can be compressed into flats with the circular light beam that four LED bulbs 4 send.
As shown in Figure 5, be simplified structure, the luminous regulator rectifier circuit of driving LED bulb in the headlight shell directly is laid in (regulator rectifier circuit employing known circuits) on the installation seat plate 5, and 7 is that electric capacity, 8 is that rectification silicon stack, 9 is regulator block among the figure, by lead each electric elements is connected.The line construction of LED bulb regulator rectifier circuit is referring to Fig. 8.
Above-mentioned beam splitter structure also can be made of the beam split eyeglass, and only needs the beam split eyeglass is fixed on the lampshade 2 and get final product.
As Fig. 6-shown in Figure 7, the Rear lamp for vehicle in the utility model lighting device on bicycle comprises shell 1, and shell 1 front portion has lampshade 2, is provided with installation seat plate 5 in the shell 1, and two LED bulbs 4 are installed on the installation seat plate 5, LED bulb 4 rear sides be provided with reflector 3 '.
In order to adjust the brightness of lamp, can corresponding increase in above-mentioned headlight and the Rear lamp for vehicle or reduce the quantity of LED bulb.In order to simplify line construction, the electric signal of Rear lamp for vehicle can be drawn from headlight simultaneously.
During use, the mouth of the triboelectricity machine on the bicycle and headlight linked to each other with connection terminal on the Rear lamp for vehicle to get final product.
The utility model is gathered a plurality of LED bulbs on the wiring board, uses electronic components such as three utmost point stabilivolts, electric capacity, rectifier diode in wiring board, and the alternating current of triboelectricity machine output on the bicycle is converted to direct current (DC).When electrical generator during to wiring board input terminal input 3-15V alternating current, by rectification, lead-out terminal is the 3.2-3.4V direct current (DC) all the time, usage condition when this value just in time satisfies the LED bulb.LED light is by the poly-circular light beam of prefocus cup, and circular light beam makes circular light beam become light and becomes the flats light beam irradiates to the road surface in bicycle the place ahead by many faceted pebbles on the lampshade, has strengthened the scope of effective lighting.
