Described a kind of straight tube LED lamp with air heat dissipation channel, is characterized in that described glass straight tube madial wall brushing has the equally distributed nano-calcium carbonate particles of one deck.
Operation principle of the present utility model is:
Straight tube LED lamp, mainly comprises electrode, lamp holder, glass straight tube, aluminium base, driver module and LED lamp pearl string.Glass straight tube both sides have left lamp holder and right lamp holder to incite somebody to action, and electrode is two pairs, is separately fixed on left lamp holder and right lamp holder.LED lamp pearl string adopts series parallel structure to connect, and is fixed on aluminium base front.The drive circuit being connected with electrode obtains power supply from left lamp holder electrode, and to LED lamp pearl string output constant current direct current.
Whole straight tube LED lamp is near symmetrical structure, but because driver module is placed on left lamp holder side, therefore, left lamp holder is larger than right lamp holder size.Left lamp holder and right lamp holder are plastic material, and right lamp holder outer surface is the face of cylinder, and left lamp holder outer surface is the left flat right oblique face of cylinder.
Glass straight tube madial wall is brushed the equally distributed nano-calcium carbonate particles of one deck, by coating, the little LED of lighting angle is carried out to diffuse reflection and transmission, has realized and has reduced dazzle, makes the uniform object of bright dipping.
Aluminium base is dumb-bell shape, and intermediate portion is divided into strip, both side ends for circular.Length and the width of strip part are chosen as suitable dimension in the middle of aluminium base, make when aluminium base fin is during apart from 1 to 2 millimeter of glass straight tube inwall, and it is grown edge, limit and is about 0.5 millimeter far from glass straight tube.Edge, two long limits, the both side ends annulus outside of aluminium base strip part are all interconnected and fixed by heat-conducting glue and glass straight tube inwall, thereby make lamp pearl region form a seal cavity, can prevent that dust from entering this space and polluting LED lamp pearl, reduce bright dipping.
There is radiating fin at the back side of aluminium base mid portion, has three to five small taper holes in the latter half of left lamp holder side and the first half of right lamp holder side, and the conehead of left lamp holder taper hole is towards glass straight tube side, and right lamp holder taper hole toward the outer side.When LED luminous, its heat distributing expands the air heat in glass straight tube, form pressure reduction with extraneous space, but because taper hole position, left side is low and end diameter is that outer imperial palace is little, high and its end diameter in taper hole position, right side is interior large outer little, hot-air more easily flows out from right side taper hole, and therefore make right side air in glass straight tube form negative pressure, and then force left side air to turn right mobile, further negative pressure is delivered to the left side of glass straight tube cavity, thereby the air that external temperature is slightly low flows into from left side taper hole, thereby, finally form one from the lower taper hole in left side, through middle aluminium base fin, a until air heat dissipation channel of the higher taper hole in right side.When described heat dissipation channel when the luminous work of LED self-assembling formation, it can help to accelerate to take away the heat that LED sends.
The utility model has the advantages that:
