Description

Luminous energy transmitter device

The present invention is a kind of luminous energy transmitter device, comprises a light energy converter.

This device is the energy with natural sunlight or optically focused electric light, or the energy of the two mixing, and each energy resource system has an independent energy collector, can provide illumination simultaneously for a plurality of squares or building.

Light wavelength with the form of electromagnetic wave transmission is 400 to 700 millimicrons.Luminous energy is sent to a plurality of lighting points from energy collector or amplitude transformer by optical conductor.The conductor output is with shadow shield or with dividing other luminosity controller control.The luminous energy of transmission projects on one or several diffusing globe, and diffusing globe directly is converted to the straight line emission of the light of all directions conduction by internal refraction and focuses on output, does not need the paraboloid of assisting, thereby has avoided local output.

In second kind of scheme, natural light is combined application with electric light light, control by light regulator.Light regulator is handled by light sensor.The heat that amplitude transformer produces is used by heat exchanger.Heat exchanger output hot water or hot-air cool off amplitude transformer simultaneously.

Focus on the radially scattering of luminous energy of output, promptly by focusing on light energy converter with its conversion or radially projection.Converter comes down to make with a kind of glass envelope that is processed into diffuser material, is connected with each light wave guide output, is converted to radial emission with the focusing emission with its output, to guarantee high efficiency diffusion.

The focused light that is produced by luminaire or sunlight is that the light wave guide of 400 to 700 millimicrons of visible spectrums transmits by wavelength.The light that is added in conductor or conductor group one end with the output of focused light form, does not need parabolic mirror to get final product irradiating object at the conductor other end (or number end).

Focus on aperture between 15 to 120 degree, this is solid transparent resin or the glue that crackle is all arranged because of every conductor ends, does not need speculum that light is exported with focus version.

Therefore, can obtain a few bundle focused lights from an independent luminaire.Owing to adopt thin light wave guide bundle, make device have flexibility, every bundle light can transmit separately on demand, the multi beam focused light promptly can be many independently places illumination is provided, as theater, memorial museum, studio, ship porthole, restaurant, automobile headlamp, boats and ships, aircraft etc., in a word, can be used on the place that all need spotlighting, and can save the parabolic mirror of common usefulness.The present invention has saved the shared space of parabolic mirror and has been converted into the part energy consumption of heat energy with them.

The light that shoots out from each focus does not have the infra-red radiation of wavelength more than 800 millimicrons, so heat significantly reduces.

The light output of gained is bigger, and don't can damage irradiated object because of the focused light heating, has also eliminated because of heat radiation or short circuit danger on fire.Optical conductor is non-conductive, not danger such as scald or electric shock during carrying.Focused light even can put into water and need not add any protection.

Transmitting device and converter thereof, and various embodiments will be illustrated by following accompanying drawing, but its application is not limited to several examples shown in the figure.Shown in the figure is a kind of simple practical design of the present invention.Therefore, all should belong within the protection domain of right of the present invention in any change aspect size, material and the ratio, as long as its fundamental property is constant, it is promptly unexceptional to bring up to new, different industrial effects.

Fig. 1 is a kind of schematic diagram of luminous energy transmitter device designed according to this invention, the form of similar calcspar.

Fig. 2 is the profilograph of amplitude transformer, electric light source group and heat exchange cooler.

Fig. 3 is the fragmentary, perspective view of conductor transmitting terminal and control dividing plate or adjuster.

Fig. 4 is the conductor transmitting terminal shown in the last figure and the schematic diagram of converter.

Fig. 5 to 8 is schematic diagrames of several examples of application.

According to above-mentioned each figure, the operation principle of device of the present invention is as follows:

Natural sunlight (1) is assembled by concentrator (2), by lens (3) straightening, bunchy projects optical collector (4), arrive each diffusing globe (12) through prism (10), conductor main line (9) and conductor (18), emission is controlled by shadow shield (15), shadow shield is contained on the support (16), is handled by controller (17).

As the natural light deficiency, then use electric light source adjuster (11) pilot (5), connect spotlight (6), light focuses on optical collector (4) by parabolic (7), transmits equally with natural light then.

Light with above form emission is incident upon square or indoor (13) that need illumination simultaneously, as shown in Figure 1.
