Abstract
The utility model relates to an LED (Light Emitting Diode) daylight lamp comprising an LED light source, a driving power source, a heat-dissipation profile, a light emergent shield and a plug. The interior of the heat-dissipation profile is hollow. The plugs are fixedly arranged at the two ends of the heat-dissipation profile. The heat-dissipation profile and the plugs at the two ends thereof define a first cavity into which the driving power source is fixed. The light emergent shield is fixedly connected with the heat-dissipation profile and forms a second cavity therewith. The LED light source is arranged in the second cavity. A slot is formed in the heat-dissipation profile. A flange is arranged at the opening of the slot. An insert piece is arranged on the light emergent shield, and further provided with a back-off member matched with the flange. After the insert piece is inserted into the slot, the back-off member is locked by the flange so that the insert piece cannot become loose and further can be not easy to drop out from the slot; therefore, the deformation amount of the light emergent shield under front stress can be reduced and the reliability of connection between the light emergent shield and the heat-dissipation profile can be well guaranteed.

Background technology
LED is a kind of energy-conserving light source of novel environmental protection, it not only can directly be converted into luminous energy with electric energy expeditiously, and have and reach tens thousand of hours to 100,000 hours service life most, possess simultaneously power saving, environmental protection, the little response of volume fast, high shatter-proof, can be applicable to low temperature environment, light source has advantages such as directionality, LED is usually used in technical fields such as illumination, demonstration.
Existing LED fluorescent tube is generally by led light source, heat sink section bar, driving power with go out parts such as light shield and form, generally make and go out light shield by PC or PMMA material, it all is positive stressed going out light shield in the existing design, in the case, be very easy to deform, use light shield and heat sink section bar matching loose, when serious even can come off, have potential safety hazard.
The utility model content
The technical problem that the utility model mainly solves provides a kind of light shield distortion and LED fluorescent lamp that come off, safer of preventing out.
For solving the problems of the technologies described above, the technical solution adopted in the utility model is: a kind of LED fluorescent lamp is provided, comprise led light source, driving power, heat sink section bar, go out light shield and plug, described heat sink section bar inner hollow, described plug is fixedly installed on the two ends of heat sink section bar, described heat sink section bar and two ends plug are enclosed first cavity, described driving power is fixed in first cavity, describedly go out light shield and fixedly connected with heat sink section bar and enclose second cavity, described led light source is located in second cavity, and described heat sink section bar is provided with slot, and slot mouth place is provided with flange, describedly go out light shield and be provided with inserted sheet, also be provided with the back-off that matches with described flange on the inserted sheet.
Wherein, described plug is fixedlyed connected with heat sink section bar by screw.
Wherein, described plug is provided with contact pin, described LED fluorescent lamp comprises first connecting line, second connecting line, the 3rd connecting line and the 4th connecting line, described first connecting line is connected contact pin and driving power with second connecting line, and described the 3rd connecting line is connected led light source and driving power with the 4th connecting line.
Wherein, described led light source and heat sink section bar glued joint or are spirally connected.
Wherein, heat sink section bar is aluminium heat sink section bar, copper heat sink section bar or silver-colored heat sink section bar.
The beneficial effects of the utility model are: the heat sink section bar of the utility model LED fluorescent lamp is provided with slot, slot mouth place is provided with flange, describedly go out light shield and be provided with inserted sheet, also be provided with the back-off that matches with described flange on the inserted sheet, after inserted sheet inserted slot, flange blocked back-off, inserted sheet can not be become flexible, more difficultly in slot, deviate from, can reduce bright dipping and cover on deflection under the stressing conditions of front, guarantee out the reliability that connects between light shield and the heat sink section bar well; Because going out photomask materials generally adopts transparent plastic to make, and has certain elasticity, uses big slightly dynamics can make back-off break away from easy accessibility from flange.
