Description
Technical field
The present invention relates to technical field of lamps, particularly a kind of tubular florescent lamp fitting with multiple planar reflectors.
Background technology
In the light fixture of the fluorescent tube that circulates on market at present, its luminaire efficiency is between 30%-45%, and average out to 40% is although inefficiency but still in a large amount of the use, causes the huge waste of the energy.The light fixture that circulates on market at present can be divided into two big classes, and a class is that light source is considered as point-source of light, and the design of all reflectors is all finished on the basis of point-source of light, and obvious this reflector has only an optical axis, is called common optical axis.Light source is that certain size is arranged in fact, and reflector can not be done very greatly, the caliber of fluorescent tube be generally reflector light delivery outlet bore 20%, the propagation of light is restricted, and can not propagate by the route of geometric optics.So fluorescent tube is considered as point-source of light and comes the design reflectivity device with common optical axis is inappropriate, reflector can not play the purpose that strengthens reflection; Another kind of the employing basically designed program, and just reflectorized material is installed on the light fixture, and as ornament, it is planar that reflector is single, do not play effect to improving luminaire efficiency.The design of above-mentioned light fixture does not utilize the due reflection characteristic of reflector well, does not play the effect that strengthens reflection, causes the waste of the not high and energy of the efficient of light fixture.
Summary of the invention
The object of the present invention is to provide a kind of tubular florescent lamp fitting with multiple planar reflectors, it has good reflection characteristic, luminaire efficiency can be brought up to more than 65% from 40%, reaches energy-efficient purpose.
The technical solution that the utility model proposed is such: a kind of tubular florescent lamp fitting with multiple planar reflectors, comprise both-end or single-ended multitube fluorescent tube side by side, reflector centers on wherein, the reflector geometric center overlaps with described fluorescent tube center, described multiple planar reflectors has eight plane reflection faces of arranging continuously at least, outwards be connected with the 1st pair of plane reflection face at least successively in the reflector vertical symmetry plane both sides of crossing the fluorescent tube central axis, the 2nd pair of plane reflection face, the 3rd pair of plane reflection face, the 4th pair of plane reflection face, the adjacent surface intersection N of the 1st pair of plane reflection face and the 2nd pair of plane reflection face, N1 is positioned on the same horizontal plane M, the 1st pair of plane reflection face is between described horizontal plane M and fluorescent tube 1, and the fluorescent tube center is to the vertical range a=30mm-40mm of described horizontal plane M.
Outside the described reflector vertical symmetry plane of crossing the fluorescent tube central axis and the 1st pair of plane reflection face and the angle α 1 between the formed plane of fluorescent tube central axis be 15 ° of-25 ° of angles.Angle α 2 between the 2nd pair of plane reflection face outside and the fluorescent tube central axis between the reflector vertical symmetry plane of formed plane and mistake fluorescent tube central axis is 55 ° of-65 ° of angles.Angle α 3 between the 3rd pair of plane reflection face outside and the fluorescent tube central axis between the reflector vertical symmetry plane of formed plane and mistake fluorescent tube central axis is 90 ° of-110 ° of angles.Angle β 1 between the 1st pair of plane reflection face and the horizontal plane M is 35 ° of-50 ° of angles.Angle β 2 between the 2nd pair of plane reflection face and the horizontal plane M is 30 ° of-37 ° of angles.Angle β 3 between the 3rd pair of plane reflection face and the horizontal plane M is 45 ° of-52 ° of angles.
Key technology of the present invention is that the tubular florescent lamp fitting reflector design is become a kind of multiple planar reflectors, promptly reflector design is become a plurality of planar combination, and these bundle of planes reflex to the zone of appointment according to the principle of direct reflection near its light (or luminous element).If the circle of being made up of many point-source of lights is regarded as in the fluorescent lamp cross section, a fluorescent tube just can be regarded as by infinite a plurality of linear light source and be formed so, just can be designed to the curved surface that an infinite a plurality of plane corresponding with each linear light source is formed.Therefore can become a plurality of planes to reflector design according to the different requirements to daylighting, the light that send light source from different angles on these planes reflexes to the direction (or place) of appointment, makes light distribution meet the designing requirement of expection.But, infinite a plurality of planes are fine in theory, but are to be difficult to realize on the technology and on producing.Adopt several planes proper so actually? this depend on the size of the light source that uses and light fixture.In the light fixture of double-end fluorescent, using many is T8 (caliber is 26mm) and T5 (caliber is 16mm), in the light fixture of one end fluorescent lamp, though the caliber that uses is T5 or T4, but it is made up of many fluorescent tubes, and as 2U, 3U and 4U etc., its sectional area ratio is bigger.In general, light fixture is done small and exquisitely as far as possible, concerning above-mentioned both-end and one end fluorescent lamp, adopts four pairs of eight planes just can reach the purpose of raising the efficiency so.In order to strengthen reflection of light, must effectively handle the surface of reflector, to improve its reflectivity.Though the method for handling is a lot, no matter adopts which kind of method, its final purpose is to improve the fineness of metal surface.The present invention is the requirement according to office or classroom illumination, and direct reflection is made on the surface of reflector, to reach best reflecting effect.
Characteristics of the present invention are except the characteristics that adopt above-mentioned direct reflection, in order to utilize reflection of light to greatest extent, first pair of plane reflection face is designed to become 40 ° with horizontal plane M, light that their can't reflect general light fixture, that send the fluorescent tube bottom reflexes on second pair, the 3rd pair and the 4th pair of plane reflection face, these planes reflex to light the zone of appointment again, have improved the utilance of light to greatest extent---and be luminaire efficiency.
Compared with prior art, the present invention has following remarkable result:
Become multiple planar reflectors because the present invention is the reflector design with tubular florescent lamp fitting, this just can bring up to 65% to the efficient of light fixture from present 40%, and promptly every tubes can raise the efficiency 25%.That is to say, the brightness of 3 * 36W lamp panel of the brightness of the energy-efficient lamp panel of 2 * 36W of the present invention and existing market circulation is suitable, use an energy-efficient lamp panel can save the material of a tubes, ballast and 1/3 lamp panel, about 25 yuans, also save the electricity consumption in 1 year of a lamp simultaneously: 36W * 8h * 365=105kWh, save about 84 yuan of the electricity charge, can save 109 yuan altogether for two.Show that according to relevant department's investigation national T8 fluorescent tube output was about 6.8 hundred million in 2006.If wherein 20% be used for efficient energy-saving lamp, need make 0.68 hundred million lamp panel, can save electricity consumption 0.68 * 105KWh=71.4 hundred million KWh (hundred million degree) in 1 year, be equivalent to 1/7 of power station, Three Gorges energy output, its meaning is very big.The electricity charge by every degree electricity are 0.8 yuan of calculating, annually add hundred million yuans of saving raw material expense: 0.68 * 25=17 because of using about 57.12 hundred million yuans of the electricity charge that efficient energy-saving lamp saves, and add up to and save 74.12 hundred million yuans.Its economic benefit is very significant.
The present invention is mainly used in the light fixture of single-ended or both-end fluorescent tube.
