Abstract

The invention provides a quartz clock with optical fiber side light irradiating the periphery of a disc face in the dark. The quartz clock is composed of a clock frame, the disc face, pointers, a quartz clock core and a light-operated circuit, wherein more than two optical fibers with whole solid cores emitting light are fixed to the periphery inside the clock frame, the two ends of each optical fiber are fixed into an optical fiber base in a sleeved mode, the optical fiber base is fixed to one corner of the clock frame, an LED lamp is arranged in front of the optical fiber base, light rays of the LED lamp are transmitted to the periphery of the disc face through the optical fibers, the weak and soft optical fiber side light irradiates the time scales of the disc face and the positions of the pointers in the dark, the halo area on the periphery inside the clock frame has little effect on the indoor dark environment, the requirement that people who like to sleep in the dark can look at the time in the dark is met, and the quartz clock can be conveniently used by people.

Description

A kind of optical fiber sidelight irradiates the crystal clock of card periphery in the dark

Technical field

The optical fiber sidelight that the present invention relates to a kind of crystal clock, particularly a kind of light control functionality irradiates the crystal clock of card periphery in the dark.

Technical background

At the crystal clock of indoor use, comprise that housing, clock dial face, clock pointer and quartz clock core form, and arrange quartz clock core in described housing at present.This crystal clock low price, good looking appearance, volume are little, Portable energy-saving, so all there is use in most of family.But this crystal clock also has certain deficiency, owing to not being with light source, when seeing the time at night, need to turn on light, otherwise just cannot see time indicator, so, there is certain inconvenience.

" a kind of artistic clock with lamp " its basic technical scheme of Chinese patent literature notification number CN202771168u on March 6th, 2013 is: the time scale of card is provided with LED lamp, when night, open the switch of LED lamp, supply module starts as the power supply of LED lamp, and the LED chip of different colours sends different light.

" a kind of light display formula quartz clock " of Chinese patent literature notification number CN2133866Y on May 19th, 1993 is to adopt: 60 optical fiber are usingd radial being arranged in card as a minute lattice demonstration, optical fiber far-end is subject to minute display lamp group glittering 60 light irradiations in turn successively, night timestamp lamp group totally 12 lamps, time display lamp group totally 24 lamps, second display lamp group totally 68 lamps, four groups of lamps form concentric circles ecto-entads and arrange.

Such scheme has solved the problem that people need to turn on light the time of seeing at night, but owing to adopting compact illumination light irradiation card, the brightness of ubiquity card at night is too high, has affected indoor dark surrounds, be not suitable for liking the most of crowd who sleeps in dark, its scope of application is subject to certain limitation.

Summary of the invention

Technical matters to be solved is the defect that overcomes above-mentioned prior art, and provide a kind of, can see pointer clearly in card time scale position, does not affect again the crystal clock of the optical fiber side irradiation card periphery of the light control functionality of liking the crowd that sleeps in dark.

Solving the technical scheme that its technical matters takes is: the utilizing optical fiber side irradiation card periphery and see the crystal clock of pointer position clearly of this light control functionality, and it includes clock frame, card, pointer, quartz clock core and light-operated circuit and forms; The inner peripheral of described clock frame is fixed with the optical fiber of two diameter 0.5mm solid core entirely lightings that flexibility is good above, optical fiber two ends are sheathed to be fixed in optical fiber base, optical fiber base is fixed on a jiao of clock frame, before optical fiber base, be provided with LED lamp, LED lamp wiring is sent to card periphery by optical fiber sidelight, and the time scale of card and pointer position are by faint soft optical fiber side irradiation; The surface of described clock frame is provided with photoresistance, is linked in sequence successively by wire with the lamination 9V battery being provided with in clock frame one side, light-operated assembly and LED lamp, forms light-operated circuit.

Clock frame inner side can be square, circular, triangle, circular inside fixed fiber because of flexibility even, comparatively suitable, number of fibers and card size and crystal clock and user's distance dependent.

Beneficial effect is: night is indoor closes after illuminating lamp grows dark, fixing entirely lighting optical fiber inside clock frame, at card periphery, form the not high halo regions of brightness, halo regions is very little on indoor dark surrounds impact, met and liked the crowd that sleeps in dark viewing time in the dark, facilitated people's use.

Accompanying drawing explanation

Fig. 1 is the structural representation of the present embodiment.

Fig. 2 is the light-operated schematic diagram of the present embodiment.

Embodiment

Below in conjunction with accompanying drawing, the present embodiment is described further.

Please refer to Fig. 1, this crystal clock that utilizes optical fiber sidelight to irradiate in the dark card periphery that the present embodiment provides, the periphery of clock frame 1 inner side is fixed with the optical fiber 5 of two above diameter 0.5mm solid core entirely lightings, optical fiber 5 two ends are sheathed to be fixed in optical fiber base 7, optical fiber base 7 is fixed on a jiao of clock frame 1, before optical fiber base 7, be provided with LED lamp 6, LED lamp 6 light are sent to card periphery by optical fiber 5 sidelights, time scale and the pointer position of the faint soft lit sideways card of optical fiber 5; The surface of described clock frame 1 is provided with photoresistance 2, is linked in sequence successively by wire with the lamination 9V battery 3 being provided with in clock frame 1 one sides, light-operated assembly 4 and LED lamp 6, forms light-operated circuit.

Please refer to Fig. 2, photoresistance RL resistance is change triggers triode with the variation of light power, and then makes the energising of LED lamp or power-off in light-operated circuit, realizes and automatically lights and close effect.The principle of work of light-operated circuit is: when extraneous light is dark, photosensitive resistance R L resistance increases, because itself and R1 form bleeder circuit, so the upper voltage drop of photoresistance RL increases, when being greater than certain value, triode vt1 conducting, and then make also conducting of triode vt2, to LED power supply, lightening LED lamp.

During indoor dark surrounds viewing time, because clock frame 1 inner peripheral is fixed with the optical fiber 5 of two above diameter 0.5mm entirely lightings, the faint soft lit sideways card periphery of optical fiber 5, can watch pointer in the residing position of card time scale easily.

Claims

1. optical fiber sidelight irradiates a crystal clock for card periphery in the dark, includes clock frame (1), it is characterized in that: clock frame (1) inner side is fixed with two above optical fiber (5).

2. a Ju a kind of optical fiber sidelight claimed in claim 1 irradiates the crystal clock of card periphery in the dark, and described optical fiber (5) is diameter 0.5mm solid core entirely lighting optical fiber.
