Abstract

The utility model relates to an optical fibre musical candle which makes the candle body and the optical fiber connect to a whole. A sound main body which is composed of a music integrated block, a light-sensitive device, and a sounder and the candle body connect to a whole. The upper end of the optical fiber is positioned in the range of illumination of the combustion of a candle core, and the lower end aligns the light-sensitive device of a music main body.

Description

Optical fibre musical candle

The utility model relates to a kind of candle, particularly a kind of musical candle.

The mode that existing musical candle, its structure utilize the enamel-covered wire short circuit to trigger mostly when the candle heart yearn burns, is burnt with the varnished insulation layer of its strand two enamel-covered wire heads together, and two line short circuits allow Music Clip send sound equipment.The disadvantage of this musical candle is unstable, when the candle of burning is blown out midway, is often still playing music because of two enamel-cover the end of a thread strands together, must cut off head this moment and make two enamel-covered wires keep insulation, and music is stopped.

The purpose of this utility model is exactly in order to address the above problem, and the optical fiber musical candle of a kind of perfect in shape and function, reliable in action, good stability is provided.

Technical solution of the present utility model:

A kind of optical fiber musical candle, it includes candle body (1) and candle heart yearn (2) thereof, it is characterized in that candle body (1) and optical fiber (3) are connected as a single entity, the sound equipment main body of being made up of music integrated block IC 1, light-sensitive device D, squealer Y (4) also is connected as a single entity with candle body (1), the upper end of optical fiber (3) is positioned at the illumination range of candle body (1) candle heart yearn (4) burning, the light-sensitive device D of its lower end aligned music main body (4).

The utility model utilizes optical fiber to conduct candle light reliably, triggers Music Clip and plays out music, in case when candle was blown out, light path was blocked, Music Clip quits work, and when lighting once more, plays out music once more, and good operating stability is used very convenient.The utility model also is provided with filtering apparatus, and it is used for preventing the interference of visible veiling glare, avoids misoperation, guarantees that optical fiber reliably conducts candle light, makes the function of musical candle more become perfect, and reliable in action is more suitable for user's demand.

Fig. 1 is a structural representation of the present utility model;

Fig. 2 is an electrical schematic diagram of the present utility model;

Fig. 3, the 4th, the johning knot composition of optical fiber of the present utility model and light-sensitive device.

As Fig. 1, optical fiber in the utility model (3) preferably is parallel to candle heart yearn (2) in the candle body (1) and passes, and its upper end is near the fire end of candle heart yearn (2).Optical fiber (3) also can with candle heart yearn (2) as one, it also is drawn along the surface of candle body (1).Music main body (4) preferably is positioned at the cavity (5) of candle body (1) bottom, and its squealer Y is positioned on the lower surface of candle body (1), correspondingly is connected with protruding nail (6) in the bottom of candle body (1), spreads out of with the sound that guarantees squealer Y.Squealer Y can adopt piezoelectric buzzer (HTD), also can adopt news Chinese percussion instrument or toy trumpet.In the utility model, the lower end of optical fiber (3) the preferably light-sensitive device D of the connecting column (7) by having concentric holes and sound equipment main body (4) fixedly is connected as a single entity, as Fig. 3,4, the lower end of optical fiber (3) penetrates from the concentric holes top of connecting column (7), light-sensitive device D puts on from the concentric holes bottom of connecting column (7), make the lower end of optical fiber (3) also contact, reach light-sensitive element D reliably to guarantee the luminous flux in the optical fiber (3) with the ball surface of light-sensitive device D is vertical.Light-sensitive device D can adopt photodiode, phototriode or photo resistance, and its sensitivity should suitably be selected, and can trigger Music Clip when guaranteeing that candle is lighted to play music.Between the ball surface of the lower end of optical fiber (3) and light-sensitive device D, be provided with coloured optical glass sheet (8), as shown in Figure 3, perhaps directly filter layer (9) is made on the ball surface of light-sensitive device D, as shown in Figure 4, they all are used for preventing the interference of strong visible light.

Operation principle of the present utility model such as Fig. 1,2, when the candle heart yearn (2) of lighted candle body (1), optical fiber (3) is synchronousing combustion with it, guarantees reliably candle light to be reached light-sensitive device D.Because the wavelength of visible light wave is at the 0.38-0.76 micron, it drops on the weak emission band of flame spectrum, so the utility model is at the afterbody of optical fiber (3) and the interface of light-sensitive device D, be provided with the coloured optical glass sheet (8) or the filter layer (9) of long-pass, its cutoff wavelength is about 0.85 micron, so just elimination visible light effectively prevents its interference.And to candle flame, because its main emission spectrum is in the far infrared wave strong point, so be not subjected to the influence of optical filter or filter layer substantially.Light-sensitive device D receives and just triggers music integrated block IC 1(model behind the candle light signal and can be LS-154B) work, make squealer Y send music.When candle was blown out, the dark resistance of light-sensitive device D increased, and the trigger end of IC1 and power supply E are isolated, and music promptly stops.If refire then and play music again again, effect is very good.

In the utility model, optical fiber (3) is selected plastic optical fiber, and its serviceability temperature scope is the narrowest, but it is the most suitable to be used for musical candle.Though the decay maximum of plastic optical fiber reaches 100dB/km, the general used optical fiber of candle is very short, be about most 15cm, decay is about 0.15dB, when this just can guarantee that candle light reaches afterbody light-sensitive device D, decay still has the luminous flux more than 96% of input, so can be ignored.And plastic optical fiber has can pass light under case of bending, and allows bending radius little, and pliability reaches advantages such as cutting is easy, easy to process, with low cost well, is better than the optical fiber of other material.
