Embodiment 1
LED (Light Emitting Diode, light emitting diode) illuminator has energy conservation, service life length etc. significant excellent
Point, as LED semiconductor technology develops, LED lamp tube will replace traditional gas electric discharge fluorescent tube.
Currently, LED lamp tube product category is various in the market, but on the whole, the tube body of LED lamp tube is primarily present two kinds of masters
Flow structure, one is aluminum profile plus PC (Polycarbonate, polycarbonate) to cover, another then be the overall plastic tube body of PC.The former manages
Body is mainly made of upper and lower two parts, and lower part is divided into the aluminum profile of semicircular heat spreading function, and LED lamp panel is fixed on aluminum profile
On, top half is semicircular light transmission PC cover, and light emitting angle is 180 degree or so, and light emitting angle is small, and metal portion partial volume
Danger of hazardous electrical discharges easily occurs during installing and using, in order to solve danger of hazardous electrical discharges, safety switch can be set in cap part.However
Adding safety switch causes lamp cap internal structure complicated, and lamp cap volume increases, and the production cost increases for fluorescent tube；The latter's lamp body is main
Composition is PC extrusion moulding long tube, in actual use, since fluorescent tube heat can cause tube body to deform buckling phenomenon,
Fluorescent tube length is longer, and bending is more obvious, and there are some potential safety problemss.Based on this, the present embodiment, which proposes LED lamp tube, to be changed
