Description
Technical field
A kind of structure of light-emitting diode lamp tube refers to the light-emitting diode lamp tube of a kind of profile as the fluorescent lamp formula especially.
Background technology
Since white light emitting diode (LED) is by a large amount of the use, lighting apparatus has just had breakthrough development, and with intensive white light emitting diode during as the light source of lighting, for reaching enough brightness, this light emitting diode must use the stronger light emitting diode of power, so heat dissipation problem often is mainly considering a little of such LED illumination lamp.
Secondly, because the light source of light emitting diode is to penetrate towards the place ahead, and the light source of non-radiation type, therefore the light source of a plurality of light emitting diodes is concentrated just becomes the problem that must consider, and how to make the light emitting diode that is straight line arrangement when arranging, can reach the again power saving of light source shadow-free on the fluorescent tube, also be an epochmaking research topic.
And industry is for led lamp, and this heat dissipation problem and light source are concentrated and do not disperseed often to have the puzzlement that can't break through.
Please referring to shown in Figure 8, be the longitudinal section with fluorescent lamp formula led lamp of heat dissipation design commonly used, mainly be provided with the tubular heat dissipating housing 60 that an aluminum and cross section are semicircle, its outside cambered surface is provided with many fins 61 mostly, and respectively be provided with catching groove 63 outside in the both side edges of this outside cambered surface, in addition the both side edges in these heat dissipating housing 60 inboard cambered surfaces relatively respectively is provided with caulking groove 62 one in, and is track with caulking groove in this 62, inlays the circuit board 70 that is provided with a plurality of light emitting diodes 71 with assembling.
In addition, transparent (acryl) lampshade 50 with respect to heat dissipating housing 60 is concaved with button rib 51 in both sides, and this detains rib 51, can buckle into the outer catching groove 63 of heat dissipating housing 60 both sides, and form a tubular fluorescent lamp formula led lamp.
The shortcoming of above-mentioned light fixture commonly used is:
(1) this aluminum metal heat dissipating housing 60 and real pyrotoxin, promptly light emitting diode 71 still has certain distance, so radiating effect is not very good.
(2) cost of this aluminum metal heat dissipating housing 60 is higher.
(3) this transparent (acryl) lampshade 50 there is no special design, and light emitting diode 71 is luminous towards the place ahead, many light sources are not directed to specific zone by deflection and cause waste, and all light is made full use of, so comparatively waste energy, very unfortunate, and light source can not be concentrated FX, illuminance deficiency then, and between each light emitting diode 71 since light do not concentrated, easily forming dark shadow on fluorescent tube so brightness is not good, is its shortcoming.
(4) this circuit board 70 is overlapped by two side connectors and compels to fix, but the joint of different size has different covers
The hole, so mould is more, and to come off easily be the another shortcoming of using always.
Summary of the invention
Main purpose of the present utility model is, the top of fluorescent tube directly is provided with breach, on this breach, be embedded the have light emitting diode aluminium base of (circuit design), making this circuit board is that itself has heat dissipation, to omit semi-circle tubular heat dissipating housing commonly used, not only save cost, and this source of emitting light and heat is directly to air heat radiation, the effect of its heat radiation is better.And tiltedly be provided with two reflective structures in the fluorescent tube, the light source of light emitting diode is gone out towards the certain angle projection after reflection, light is collected penetrate in fixing zone, to promote brightness.
The structure technology scheme of the light-emittingdiode utmost point spot pipe of this case is, include: one has the fluorescent tube of suitable length, be transparent tubular shell, above its radial section, offer breach vertically, and the two opposite sides at this breach are provided with means for mounting coupling parts, and this means for mounting coupling parts is mainly the track of groove shape; And at the inner edge of fluorescent tube, with the vertical profile cross section, the below slightly on the both sides of central vertical line, each is formed with a rib clamping structure relatively, and this two ribs clamping structure extends axially along the inner wall that is arranged on fluorescent tube;
One microscler aluminium base, edge is provided with a plurality of light-emittingdiode utmost point pipes, and this aluminium base is inserted between two means for mounting coupling parts of fluorescent tube breach;
Two reflective structures are divided into the both sides in the fluorescent tube.
Thus, good, cost reduction that the dynamical light-emitting diode lamp tube of this case not only dispels the heat, and light is concentrated and brightness is improved, and has promoted the quality of light fixture.
