Abstract

The utility model provides a special lamp cylinder used for an LED lamp, which comprises a lamp cylinder body and an aluminum base. A limit edge is arranged on the internal edge of the lower opening of the lamp cylinder body; a dustproof light transmission plate is movably arranged on the top of the limit edge; a reflection cup is movably arranged on the upper part of the dustproof light transmission plate. Dye to the technical proposal, the reflection cup of the LED lamp cylinder can be manufactured into various reflecting angles and be replaced by other reflection covers at any time according to the lighting requirement. The utility model has the advantages of various reflecting angles, stable LED light source, dust collection and increasing the radiating effect.

Description

A kind of special lamp tube of LED lamp

Technical field:

The utility model relates to technical field of lighting fixtures, refers in particular to a kind of special lamp tube of LED lamp.

Background technology:

Advocate energetically in country under the overall situation of energy-conserving and environment-protective, the energy-conserving and environment-protective product more and more is subjected to consumers in general's favor, for example, emerging product LED lamp in illuminating industry, more energy-conservation because of it than electricity-saving lamp, colour rendering is higher, the gesture that replaces is arranged greatly, but also there are some shortcomings in it, for example Design of Luminaires falls behind, and the light fixture that is used with the LED lamp at present is owing to its reflector partly is one-body molded with lamp tube main body, when running into requirement difference crevice projection angle, must change together with light source by the lamp tube, this makes the cost height of producing and using, and influences its further popularization; The installation (as Fig. 1 and Fig. 2) of lamp tube at present is to utilize the annulus disposed thereon 01 and the threaded engagement of lamp tube 02 to be installed on the lamp plate in addition, this just requires perforate on lamp plate, just can load onto the lamp tube, installation and removal are all more consuming time, reduce the installation effectiveness of LED lamp.

Summary of the invention:

The purpose of this utility model is in order to overcome above-mentioned the deficiencies in the prior art, a kind of LED special lamp tube that can change reflector as required to be provided.

For achieving the above object, the technical scheme that the utility model provides is: a kind of special lamp tube of LED lamp, it includes lamp tube main body and aluminum base, on the under shed inside edge of lamp tube main body, be processed with position-limited edge, activity is placed with dustproof light transmission piece on this position-limited edge top, is provided with reflector in the top movable of dustproof light transmission piece.

By being threaded, and have the screw of Gong installing and using between described aluminum base and the lamp tube main body on the top of aluminum base.

Described dustproof light transmission piece is the circular glass sheet.

Described reflector is the flare shape that caves inward.。

After adopting technique scheme, the reflector on the LED lamp lamp tube can manufacture various reflection angles, according to lighting requirement, changes other reflection shield at any time during use, has multiple reflective angle, firm led light source, dustproof and raising radiating effect.

Description of drawings:

Fig. 1 is the three-dimensional structure diagram of existing LED lamp tube;

Fig. 2 is the three-dimensional exploded view of existing LED lamp tube;

Fig. 3 is the cutaway view of LED lamp tube of the present utility model;

Fig. 4 is the three-dimensional exploded view of LED lamp tube of the present utility model.

The specific embodiment:

See shown in accompanying drawing 3 and the accompanying drawing 4, the special lamp tube of the LED lamp of this preferred embodiment includes lamp tube main body 1 and aluminum base 5, on the under shed inside edge of lamp tube main body 1, be processed with position-limited edge 2, activity is placed with dustproof light transmission piece 3 on these position-limited edge 2 tops, is provided with reflector 4 in the top movable of dustproof light transmission piece 3.

Be connected by screw thread 6 between described aluminum base 5 and the lamp tube main body 1, the heat of LED is transmitted better, radiating effect improves greatly, and have the screw of Gong installing and using 7 on the top of aluminum base 5, this screw 7 has been arranged, the installation of lamp tube can directly be contained on the lamp plate with screw threads, and is easy for installation, quick.

Described dustproof light transmission piece 3 is the circular glass sheet.

Described reflector 4 is the flare shape that caves inward.

The embodiment of the above is preferred embodiment of the present utility model only, is not to limit practical range of the present utility model with this, so the equivalence that all shapes according to the utility model, structure and principle are done changes, all should be covered by in the protection domain of the present utility model.
