Description
Technical field
The present invention relates to a kind of reflector and energy-saving lamp, as straight tube fluorescent lamp reflector or single-ended single U-shaped list H shape fluorescent lamp reflectors, particularly a kind of single tube straight tube fluorescent lamp reflector or many reflectors are combined into multitube straight tube fluorescent lamp tool, as support or grid light fixture, belong to field of lamp illumination.
Background technology
Existing lighting reflector such as sodium vapor lamp Metal halogen lamp spot light reflector, Luminaire efficiency is not high, and the spot light reflector structure is all fairly simple at present, and its cross section mostly is single parabolic structure, and is poor to the control of reflection of light path.Light fixture for straight tube fluorescent lamp, point or line source master light-reflecting portion adopt single parabolic structure or single globoidal structure, the light that discharge tube is upwards the sent device reflected back discharge tube that is reflected, be subjected to stopping of discharge tube and can not reflect away, make that this part higher light of ratio can not obtain utilizing, and can make discharge tube heating higher, influence the lamp life-span, and very the reflective surface surface design of complexity may make the part reflection of light energy consumption is big often.In addition, when adopting compact shape one end fluorescent lamp or adopting two straight tube fluorescent lamps simultaneously, the single parabolic reflector is because of having only a focus, so can not form the situation of the highest light efficiency utilization that two discharge tubes all are in the focus of reflector.Therefore, traditional reflector can not reflect the light that two-tube light source sends fully, makes the utilization ratio of light source not ideal enough.
In the existing in addition two-tube straight tube fluorescent lamp light fixture, there is the cross section of employing to be a semicircle or approaching semicircular main light-reflecting portion, reflect a straight tube fluorescent lamp, promptly a straight tube fluorescent lamp is installed on a semicircle in the reflective phase, another root straight tube fluorescent lamp is installed in another semicircle reflector, and two semicircle reflectors fuse.The disadvantage of this reflector is that light its reverberation after semicircle reflector reflection that discharge tube up penetrates has more being reflected on the discharge tube, and Luminaire efficiency is not ideal enough equally.
Chinese patent discloses a kind of reflector (publication number: CN201177213Y) that is used for the double tube fluorescent lamp tool, this reflector has the reflective surface of U type, the cross section of each side reflective surface is formed by first parabola and second parabola, on first parabolic focus that is centered close to each side reflective surface of two discharge tubes that level is installed.Reflector upwards has a protruding optical splitter, is used for the light that discharge tube upwards sends is reflexed to reflector two wall parabola reflective surfaces, and the effective light that is further used as light fixture partly projects.The above-mentioned reflector of above-mentioned reflector just advances trickle this of U-shaped reflector, though the light that discharge tube upwards can be sent reflects to a certain extent, but the height of its optical splitter is little, the light that discharge tube is upwards sent reflects the outer DeGrain of reflector, and the part light of emission obliquely meeting directive fluorescent tube; In addition, the structure that the reflective surface of its both sides all adopts first parabola and second parabola to form, because fluorescent lamp is one and has larger-diameter cross section disc illuminating source, high-voltage gas discharging light is a long discharge pipe, it or not a choice refreshments luminous light source, so the parabolic focus rule not exclusively is fit to fluorescent lamp or gas-discharge lamp, thereby can cause the not high enough problem of the good inadequately reflection efficiency of the illuminated working face uniformity, wherein first parabola and second parabola to discharge tube upwards and reflection of light light obliquely still can reflex on the discharge tube morely, thereby the light that can't well discharge tube be sent light reflects, and double-paraboloid line reflection face is unfavorable for the photodistributed uniformity.
Summary of the invention
The object of the invention is to provide a kind of light that can be preferably discharge tube be upwards sent in 180 ° of scopes to avoid fluorescent tube and reflexes to the high light efficiency reflector that the outer a kind of reflector efficiency of reflector can reach 90%-98%, has solved existing reflector and should be the not high all disadvantages of reflector efficient that disadvantage that structural design exists causes.
Above-mentioned technical purpose of the present invention mainly solves by the following technical programs: comprise main light-reflecting portion, at least main light-reflecting portion forms
