As further improvement, the material of lamp housing is glass.When adopting this glass tube structure, aluminium base is fixed in the glass tube cavity or on inwall, glass tube has advantages of that light transmittance is high, is conducive to improve the light output efficiency of light fixture, according to the actual conditions of using, can use ground glass or clear glass.

As further improvement, the material of reflecting part is a kind of in specular aluminium, mirror-like silver, PET.Generally, consider the factor of price and stability of material, preferred specular aluminium reflector, also can adopt PET (PETG) reflectorized material, the MCPET material produced of Furukawa for example, this material has reflecting rate high (98%), the advantage that cost is low.

As further improvement, reflecting part is plane or cambered surface.When reflecting part was the plane, preferably all high in the both sides of the light emission direction of LED light source had a reflecting part, and the angle between two planes is 5～170 °, and more excellent is 30～150 °., only needs are adjusted the size of angle, can regulate and control the beam angle of LED strip light; When reflecting part is cambered surface, optical assembly can make the light that the LED strip light is sent be congregational rate on certain angle, be on other angles and disperse effect, adjust the radian of reflecting assembly, can and then adjust the luminous congregational rate of LED strip light and disperse effect.

Technique effect

Compare with existing LED fluorescent lamp with conventional fluorescent, the LED fluorescent tube that the utility model provides, increased reflecting assembly in pipe, make light to send in the required angle of user, can present the effect of assembling or spreading, more meet user's requirement, simultaneously more energy-conservation, only need lower powered LED fluorescent lamp, can realize traditional illuminating effect.
