Description

Improved lamp tube structure of light-emitting diode

Technical field

The utility model relates to a kind of light emitting diode, relates in particular to a kind of improved lamp tube structure of light-emitting diode.

Background technology

Before so-called " Electricity-saving lamp bulb " do not ask the city as yet, generally used light source to be generally tengsten lamp and fluorescent lamp, because the higher and power consumption of caloric value of tengsten lamp, therefore in the place of business of a large amount of electricity consumptions of needs as illumination by people, even general family, prefer the use fluorescent lamp usually.Recently, appeal in green group and government under the agitation of using electricity wisely that the use of Electricity-saving lamp bulb is as day by day popularizing as surging forward; Wherein, because little, the little power consumption of volume, ((lightemitting diode is called for short LED) becomes photoelectric cell indispensable in the daily life to light emitting diode already.More progressive and make in the higher epoch of the brightness of LED at advanced IT application and material, the application of LED is also more and more wide, no longer be confined to limited application, and then the development of the lighting of marching toward, the application of outdoor photoelectric field such as traffic sign and outdoor billboard even.

The basic structure of LED is an electroluminescent semi-conducting material, places on the leaded shelf, uses epoxy sealing then all around, to protect inner heart yearn.It is multiple that present LED has bulb type, plane etc., and be made into the form of similar fluorescent tube, and attempt replaces fluorescent lamp as economizing electric light source.

Existing LED fluorescent tube, primary structure is that a circuit board that is provided with several LED elements is set in the fluorescent tube of a light-permeable, a cap head with two terminals is then made up at the two ends of fluorescent tube respectively, electrically connect with electric wire between two-terminal and the circuit board, when fluorescent tube is combined in the cap head and terminal and cap head are electrically connected, after feeding electric current, can make LED luminous.The cap head of aforementioned existing LED fluorescent tube and the combining structure of fluorescent tube have two kinds haply, and wherein a kind of is behind the inboard of cap head coating adhesive agent, lamp tube ends is inserted in the cap head, and then it is fixing to utilize adhesive agent to bind again.Another kind of structure then is to be provided with fastening structure between lamp tube ends and cap head, that is is provided with button hole in lamp tube ends, and the cap head then is provided with elastic clasp, when making lamp tube ends be inserted in two cap heads respectively, is able to buckle into the button hole of fluorescent tube and fix by clasp.

The cap head of aforementioned existing LED fluorescent tube and the combining structure of fluorescent tube, fixed effect to a certain degree no doubt is provided, yet, in processes such as transportation, storage, installation, if run into bigger bump, impact, drop or other external force is done the time spent, usually adopt the fluorescent tube of transparent plastic material manufacturing to have no to damage, but the cap head is easy to get loose or damaged from fluorescent tube, causes the danger in the electricity consumption; And costing an arm and a leg of LED fluorescent tube, if thereby cause cap head displacement, damaged, get loose and must change, with the burden that causes economically.

The utility model content

Technical problem underlying to be solved in the utility model is, overcome the above-mentioned defective that prior art exists, and a kind of improved lamp tube structure of light-emitting diode is provided, so as to promoting the bond strength of fluorescent tube and cap head, avoid being impacted or other external force causes cap head and fluorescent tube disengaging as the time spent.

The technical scheme that its technical problem that solves the utility model adopts is:

A kind of improved lamp tube structure of light-emitting diode is characterized in that, comprising: a fluorescent tube is provided with light emitting diode module in the pipe; The tube wall of this lamp tube ends is provided with at least one screw; Two cap heads are respectively equipped with two-terminal, and the sidewall of this cap head is provided with the hole of at least one corresponding described screw; At least one retaining element after described cap head is combined in this fluorescent tube, utilizes this retaining element to pass this hole and screw and this fluorescent tube and fluorescent tube is fixed.

Aforesaid improved lamp tube structure of light-emitting diode, wherein retaining element is a screw.

Aforesaid improved lamp tube structure of light-emitting diode, wherein retaining element is a rivet.

So as to promoting the bond strength of fluorescent tube and cap head, avoid being impacted or other external force causes cap head and fluorescent tube disengaging as the time spent.

Feature of the present utility model, be to utilize such as elements such as screw or rivets as the fluorescent tube of LED fluorescent tube and the retaining element of cap head, make cap head and fluorescent tube be obtained more firm combining, do the time spent being subjected to bigger external force, can not get loose yet, be shifted and damaged problem, cause economically loss thereby avoid frequently changing fluorescent tube.

The beneficial effects of the utility model are, so as to promoting the bond strength of fluorescent tube and cap head, avoid being impacted or other external force causes cap head and fluorescent tube disengaging as the time spent.
