Abstract

The utility model provides a tube-in-tube fluorescent lamp comprising a sheath tube, a light emitting tube, an inductive module and a main control circuit board; wherein, the light emitting tube, the main control circuit board and the inductive module are all arranged in the sheath tube; the main control circuit board is connected with the inductive module via a double circuit line; the outer side at end part of the sheath tube is provided with a plug which can externally connect with a power supply. The utility model is characterized in that: a mirror reflection layer is arranged on the back-side sheath tube that needs to be illuminated. Adopting the above structure, the utility model does not need the second irradiation of lights on the irradiation surface through the reflection of the mirror reflection layer. With the same power, the irradiation intensity and brightness of the fluorescent tube can be improved greatly. Compared with the prior art, the utility model has the advantages of improving irradiation intensity and brightness with the same power of the fluorescent tube.

Description

A kind of bushing type fluorescent lamp

Technical field

The utility model relates to a kind of bushing type fluorescent lamp, particularly a kind of bushing type fluorescent lamp that does not need starter, electric ballast.

Background technology

The patent No. is that 200320101358.0 Chinese patent discloses a kind of bushing type daylight lamp apparatus, comprise sleeve pipe, luminous tube and Inductive component, it is characterized in that also including the main control wiring board, described luminous tube, the main control wiring board, Inductive component is sealed in the sleeve pipe, described main control wiring board is by diode, the rectification circuit that resistance and electric capacity are formed, circuits for triggering and filter circuit, described main control circuit is connected by the double loop line with Inductive component, and there is the plug that can link to each other with external power source in the described pipe outside.This device does not need filament is heated, and directly utilizes high frequency to make lamp luminescence, has improved service life of fluorescent tube and energy-conservation greatly.But at subway, the tunnel, the underground parking, general merchandise supermarkets etc. some need the place of higher illumination intensity to seem that sometimes brightness is not enough.

The utility model content

The purpose of this utility model is in order to solve above-mentioned the deficiencies in the prior art, does not need to increase fluorescent tube power and just can improve exposure intensity and provide, and increases a kind of bushing type fluorescent lamp of brightness.

The purpose of this utility model is achieved by the following technical solution: a kind of bushing type fluorescent lamp, comprise sleeve pipe, luminous tube and Inductive component, the main control wiring board, described luminous tube, main control wiring board, Inductive component is sealed in the sleeve pipe, described main control circuit is connected by the double loop line with Inductive component, and there is the plug that can link to each other with external power source in the described cannula tip outside, it is characterized in that on the reverse side sleeve pipe of needs irradiation specular layer being set.

Described specular layer is arranged on internal surface of sleeve pipe.

Described specular layer is arranged on sleeve outer wall.

Described specular layer also can be made into the thin rectangular employing inserted mode of circular arc and insert in the sleeve pipe.

Half circular arc of described specular layer overlapping casing tube.

The utility model is owing to adopted said structure, with the reflection by specular layer of the light that do not need shadow surface once more according to shadow surface, under the power that does not increase fluorescent tube, will improve exposure intensity greatly, increase brightness, the utility model compared with prior art has not to be needed to increase fluorescent tube power and just can improve exposure intensity, increases the advantage of brightness.
