Abstract
The utility model discloses a light emitting diode (LED) fluorescent lamp tube and belongs to the technical field of semiconductor lighting. The LED fluorescent lamp tube comprises a glass tube, a plastic tube, a circuit board, an LED light source and two lamp heads, wherein the plastic tube, the circuit board and the LED light source are all arranged in the glass tube in sealing mode. The two lamp heads are respectively arranged on two ends of the glass tube, and the LED light source is fixed on the circuit board. A clamp groove is arranged in the plastic tube, and the circuit board is fixed in the plastic tube through the clamp groove. The circuit board divides the cylindrical plastic tube into two cavities which have cross sections in a circular-arc shape. The position of the LED light source is adjusted through adjustment of the position of the circuit board in the cavities of the plastic tube, so that the LED light source can be prevented from being placed in the position of the diameter of a lamp tube, and luminous angles of the lamp tube are increased. The circuit board is made of environmental-friendly materials such as ceramic substrates and epoxy glass fabric plates so as to dissipate heat emitted by the LED light source in energy-saving and environmental-friendly mode, and production cost is reduced.
Description
Technical field
The utility model discloses a kind of LED fluorescent tube, belong to the technical field of semiconductor lighting.
Background technology
Semiconductor lighting is because of having energy-saving and environmental protection, responding advantage fast developments such as fast.In the room lighting field, the LED fluorescent tube is with its energy-saving advantages, and the traditional fluorescent-lamp-type fluorescent tube of forward is initiated challenge, constantly replaces the latter.
The overall structure of existing LED fluorescent lamp can be divided into two types: the first kind is that the PC lampshade adds aluminium radiator; Fixing aluminium base on a strip aluminium radiator; Fixing some led light sources on aluminium base then are fixed on the PC lampshade on the strip aluminium radiator then, carry out the connection of circuit then; The advantage of this type LED fluorescent lamp is a technology maturation, and threshold is lower; Yet shortcoming also is tangible: mainly be that cost is high, because light source generally is positioned at the diameter place of fluorescent tube, make that the space luminescence angle of fluorescent tube is also less than normal in addition, do not reach the lighting angle of conventional fluorescent type fluorescent tube.Second type is that wiring board adds glass tube, and some led light sources are fixing in the circuit board, applies some colloids at circuit backboard face then and is bonded at wiring board in the glass tube; Then carry out the connection of circuit,, reduced cost though this type LED fluorescent tube can not be applied to aluminium radiator; But shortcoming also is tangible: glass tube is frangible, and especially after the glass tube fragmentation, led light source directly exposes out; Have potential safety hazard, and the led light source issued light is also comparatively dazzling, is unfavorable for people's vision.
Summary of the invention
The utility model technical problem to be solved is to the deficiency of above-mentioned background technology, and a kind of LED fluorescent tube is provided.
The utility model is for realizing that above-mentioned utility model purpose adopts following technical scheme:
A kind of LED fluorescent tube comprises: glass tube, plastic tube, wiring board, led light source, two lamp holders; Wherein, Plastic tube, wiring board, led light source all are encapsulated in the glass tube; Two lamp holders are installed in the two ends of glass tube respectively, and said led light source is fixing in the circuit board, is provided with draw-in groove in the said plastic tube; Wiring board is fixed in the plastic tube through draw-in groove, and said wiring board is with the cylindrical plastic pipe cavity that to be divided into two cross sections be circular arc.
Further, the ratio of the area of two cavity cross sections is 1:0.02-1:0.5 in said a kind of LED fluorescent tube.
Further, the plastic tube of said a kind of LED fluorescent tube is PC pipe or PMMA pipe, and the light transmittance of said PC pipe or PMMA pipe is 50%-95%, and mist degree is 0.5%-99%.
Further, the light transmittance of the glass tube of said a kind of LED fluorescent tube is 50%-99%, and mist degree is 0.5%-99%.
Further, in said a kind of LED fluorescent tube, the spacing between glass tube and the plastic tube is 0-5mm.
Further, the wiring board of described a kind of LED fluorescent tube is copper base or ceramic substrate or epoxy resin bonded fiber.
The utility model adopts technique scheme, has following beneficial effect: regulate the position of led light source through regulating the position of wiring board in the plastic tube cavity, thereby avoid led light source to be positioned at the diameter place of fluorescent tube, the lighting angle of the fluorescent tube of increase; Select for use environment-friendly materials such as ceramic substrate, epoxy resin bonded fiber as wiring board, the heat that the led light source that leaves to energy-conserving and environment-protective sends has reduced production cost.

Label declaration among the figure: 1, glass tube, 2, plastic tube, 3, wiring board, 4, led light source, 5, lamp holder.
The specific embodiment
Be elaborated below in conjunction with the technical scheme of accompanying drawing to utility model:
Like Fig. 1,2,3, the LED fluorescent tube shown in 4; Comprise glass tube 1, plastic tube 2, wiring board 3, led light source 4, two lamp holders 5; Plastic tube 2, wiring board 3, led light source 4 all are encapsulated in the glass tube 1, and two lamp holders 5 are installed in the two ends of glass tube 1 respectively.Led light source 4 is fixed on the wiring board 3, is provided with draw-in groove in the plastic tube 2, and wiring board 3 is fixed in the plastic tube 2 through draw-in groove, and wiring board 3 is with cylindrical plastic pipe 2 cavity that to be divided into two cross sections be circular arc.
The position of wiring board 3 in plastic tube 2 can be regulated, and makes that the ratio of area of cross section face of two cavitys is 1:0.01-1:1, and the area of two cross sections is than preferred 1:0.02-1:0.5, just makes wiring board 3 more near the top of plastic tube 2.Can avoid led light source 4 to be positioned at the problem at tube diameter place like this, and then make the lamp luminescence angle that produces bigger, approach conventional fluorescent type fluorescent tube more.
Seeing that traditional LED fluorescent tube aluminium substrate has increased cost as wiring board 3, the utility model selects for use copper base, ceramic substrate, epoxy resin bonded fiber to do wiring board 3.Copper base, ceramic substrate, epoxy resin bonded fiber have also reduced production cost when guaranteeing wiring board 3 heat dispersions.
The light transmittance of glass tube 1 is 50%-99%, preferred 70%-99%, and mist degree is 0.5%-99%, preferred 20%-80%; Through improving the mist degree of glass tube, can make the outward appearance of glass tube approach the outward appearance of conventional fluorescent glass tube more, the light that simultaneously fluorescent tube is sent is softer, reduces dazzle.Spacing between glass tube 1 and the plastic tube 2 is 0-5mm, preferred 0-0.5mm.
It is thus clear that the described LED fluorescent tube of the utility model is regulated the position of led light source through regulating the position of wiring board in the plastic tube cavity, thereby avoid led light source to be positioned at the diameter place of fluorescent tube, the lighting angle of the fluorescent tube of increase; Select for use environment-friendly materials such as ceramic substrate, epoxy resin bonded fiber as wiring board, the heat that the led light source that leaves to energy-conserving and environment-protective sends has reduced production cost.Said specific embodiment is merely one of the utility model and optimizes embodiment, and any utility model that meets the utility model aim is created or in the improvement patent of making under the guidance of the utility model aim all within the protection domain at the utility model.
