The utility model content
Have in order to overcome existing LED fluorescent tube that optically focused property is poor, the light source utilization rate is low, illuminating area and the little deficiency of uniformity coefficient; The purpose of the utility model is to provide a kind of new LED fluorescent tube, and not only light efficiency is good for it, the light source utilization rate is high, illuminating area is big and evenly.
For reaching above-mentioned technical purpose; The utility model adopts following technical proposals: design a kind of Novel LED fluorescent lamp pipe; Comprise: heat dissipating housing, lamp cover, led driver, be provided with the pcb boards of some LED lamp pearls, wherein: lamp cover is connected in the heat dissipating housing below, and forms a fluorescent tube; Lamp tube ends is arranged with the end cover, and led driver is placed in one of them end cover; In heat dissipating housing, axially be provided with together ccontaining in order to fixing pcb board, this diameter of ccontaining is extended with the support chip that is connected one with heat dissipating housing less than the diameter of heat dissipating housing ccontaining both sides, and this support chip is provided with reflector layer.
The utility model also further has following more excellent technical scheme:
Angle between described support chip and ccontaining is greater than 15 degree.
Described support chip has arcuate structure.
Described heat dissipating housing and ccontaining of being arranged in it are one-body molded through the grinding tool extruding with support chip.
Described support chip upper end has an extension respectively, and this extension has formed a pcb board slot jointly below ccontaining.
Described support chip lower end is respectively arranged with a step surface, has formed a draw-in groove jointly with the heat dissipating housing both sides of the edge, and lamp cover embeds and is connected in the heat dissipating housing below in the draw-in groove.
Described heat dissipating housing is an aluminium section bar.
Owing to adopt above technical scheme; The pcb board that is provided with some LED lamp pearls is fixed on ccontaining in the heat dissipating housing, and the support chip of both sides and ccontaining form a prefocus cup cover, and the light of LED lamp pearl emission throws after by optically focused; Make light have directionality, strengthened illumination effect; Compared with prior art the utlity model has following beneficial effect: strengthened optically focused property, improved the utilization rate and the light efficiency of LED light; It is simple in structure, is worthy of popularization.
