Description
Technical field
The utility model relates to light fixture, is specifically related to a kind of with the fluorescent tube of high-power LED chip as light source.
Background technology
Along with the enhancing gradually of people's energy-conserving and environment-protective consciousness, occurred variously substituting conventional incandescent, fluorescent lamp light fixture as light source with brightness height, long LED of life-span.For can be general with fluorescent tube, mostly same or similar with LED with fluorescent tube as the fluorescent tube profile of light source, but a great difference is arranged on internal structure.Present LED fluorescent tube is to establish a strip circuit board between the attaching plug at two ends, and the one side of circuit board is provided with several led light sources, and another side is provided with the radiator of LED.Because the separation of circuit board, this fluorescent tube only is provided with the one side of led light source can be luminous, the one side of radiator can not be luminous, so lighting angle can only reach 180 °, this has just proposed very high request to setting angle, must be during installation with the zone of luminous one side towards need illuminations, otherwise just can not reach lighting requirement.And the lighting angle of fluorescent tube is 360 °, use the light fixture of fluorescent tube not need to consider lighting angle, this just causes when using prior art LED fluorescent tube replace fluorescent lamps pipe, can not guarantee that luminous one side is fully towards the zone of need illuminations, this not only can cause light losing, also the dead angle of throwing light on may occur.
The utility model content
The utility model LED fluorescent tube technical problem to be solved provide a kind of 360 ° can both be luminous the LED fluorescent tube.
The overall shape of the utility model LED fluorescent tube is as the conventional fluorescent lamps pipe, attaching plug is established at both ends, the main part at middle part is a glass fluorescent tube, between two ends attaching plug and fluorescent tube respectively from far away the nearly middle side of side direction set gradually insulating trip, radiator and high-power LED chip, be provided with a cavity at the radiator distal end, constant-current source is set in the chamber; Wherein, insulating trip is the circular gasket that diameter and attaching plug adapt, and makes with insulating materials, is located between attaching plug and the radiator, is used for radiator and attaching plug electricity are isolated; Radiator is made up of cylindrical stem stem and the fin of being located at the stem stem periphery wall, and radiator diameter and attaching plug adapt, and makes with heat conductivility good metal material, preferred aluminium.Constant-current source is located in the cavity of radiator stem stem distal end, and an end is electrically connected with the attaching plug electrode, and the other end is electrically connected with high-power LED chip; High-power LED chip is fixedly connected on the nearly middle-end of radiator stem stem, is provided with the insulating heat-conductive glue-line between led chip and radiator, with led chip and radiator insulation; The fluorescent tube end loops is around in the led chip periphery and fixedlys connected with the nearly middle-end of radiator.
As optimization, be provided with reflection shield in the nearly middle-end of radiator stem stem around high-power LED chip, reflective surface is towards fluorescent tube one side.Reflection shield can be plate shaped or tubaeform.
As optimization, be provided with lens in the led chip front portion, lens can be convex lens, concavees lens or phenanthrene lens like this, regulate the light transmission direction.
As optimization, the radiator length range is 2cm to 10cm, and diameter range is 2cm to 5cm.
As optimization, the fin on the radiator stem stem can be to be arranged in parallel or by the geometrical pattern setting, increase the aesthetic effect of whole fluorescent tube.
As optimization, the cross sectional shape of heat radiator fin can be " one " font, also can be " T " font.
As optimization, the making material of radiator is that copper, aluminium, stainless steel, aluminium copper facing or copper are silver-plated.
The utility model LED lamp tube structure is simple, and energy-conserving and environment-protective are both artistic and practical, both has been applicable to straight fluorescent tube, is applicable to that also annular lamp tube, service life were 50,000 hours.The interior fluorescent material of the optical excitation fluorescent tube that high-power LED chip sent that is located at lamp tube ends sends the light of homogeneous and bright, it is 360 ° of center that its lighting angle scope reaches with the fluorescent tube, as conventional fluorescent setting angle is had no requirement, meet people's use habit.
