Description
Technical field
The utility model relates to lighting field, specifically involves in a kind of LED fluorescent tube
Background technology
Advantages such as the LED fluorescent lamp is low because of its energy consumption, the life-span is long just progressively replace traditional fluorescent lamp.Because the caloric value of LED fluorescent lamp is big, it is important that the problem of heat radiation just still shows.Existing technical scheme is that the circuit substrate that will led light source be installed is fixed on the metal lamp housing, and the heat that led light source is produced distributes by lamp housing.Though this scheme can solve heat dissipation problem preferably, but still have certain limitation: when the LED fluorescent lamp suffered high-pressure electrostatic, electric charge directly reached circuit substrate from lamp housing, was very easy to cause the puncture of circuit, thereby destroyed circuit substrate and led light source.Otherwise the user is unavoidable directly touching metal lamp housing when safeguarding or light fixture is installed, if the light fixture electric leakage just gets an electric shock the user easily, has potential safety hazard.
Summary of the invention
The utility model proposes a kind of LED fluorescent tube, increase the insulating properties between circuit substrate and the fluorescent tube, prevent that extraneous high-pressure electrostatic to the potential safety hazard of infringement or the lamp circuit electric leakage of lamp interior circuit, promoting service life and the security of LED fluorescent lamp greatly.Its technical scheme is as follows:
A kind of LED fluorescent tube, comprise body, be installed on lampshade on the body and the power connector at body two ends, it is characterized in that: described body is provided with cooling platform with respect to lampshade one side, and this cooling platform is provided with for the substrate protective sleeve that is connected led light source substrate and cooling platform; The front of described substrate protective sleeve offers for the mounting groove that the led light source substrate is installed, and its bottom surface and described cooling platform are fitted.
In the such scheme, the substrate protective sleeve of setting up can completely cut off external high pressure static effectively, the safety of protection led light source substrate.Described substrate protective sleeve adopts silica gel compound to make; possesses thermal conduction characteristic preferably; and between substrate protective sleeve and the led light source substrate, between substrate protective sleeve and the cooling platform by the silica gel involution, the heat that makes led light source produce conducts to body by the substrate protective sleeve equably.
Further, described cooling platform is provided with the axisymmetric shelves bar along the body center, and an outside side of described shelves bar is extended first positioning strip; Form clamping part between described first positioning strip and the described platform, the chimb that is provided with the lampshade edge is interlocked, this structure make lampshade installation, the dismounting more simple and easy.
Further, an inside side of described shelves bar is extended second positioning strip, forms a T type groove between described second positioning strip and the platform, and described substrate protective sleeve is placed in the T type groove.The lower surface of described second positioning strip is close to described substrate protective sleeve side, and the substrate protective sleeve that the led light source substrate is installed can embed along described mounting groove from the body two ends, realizes the location of substrate protective sleeve.
Further, be provided with a pair of raised line in the tube chamber of described body, form guide groove between the inwall of described raised line and platform one side.By the installed part that cooperates with this guide groove, can realize the built-in device mounting of tube chamber more conveniently.
As a kind of improvement of such scheme, also be provided with the power protection cover of a hollow in the tube chamber of described body, the LED driving power is built in the middle of this power protection cover.Described power protection cover can prevent that external high pressure static from causing damage to driving power, the safety of protection driving power.
Further, the side correspondence of described power protection cover is provided with the convex edge that can be embedded in above-mentioned guide groove and slide along described guide groove.Described power protection cover positions by the guide groove of chimb fit tube cavity wall, installs very convenient.
Further, described tube wall is provided with bar shaped heat radiation line, both can increase area of dissipation, also makes the light fixture outward appearance possess certain aesthetic feeling.
Characteristics of the present utility model are effectively to prevent external high pressure static to the infringement of internal circuit, the electric shock accidents that also can avoid the internal circuit electric leakage to cause simultaneously, and the security that improves light fixture greatly is fit to promote the use of.

The specific embodiment
By reference to the accompanying drawings following, one of the utility model embodiment is described:
As shown in Figure 1 and Figure 2, a kind of LED fluorescent tube comprises aluminium matter body 2, is installed on lampshade 1 on the body, the power connector 5 at substrate protective sleeve 3, power protection cover 4 and body two ends.
As shown in Figure 3, Figure 4, described body 2 is provided with a cooling platform 21, and this cooling platform 21 is provided with the axisymmetric shelves bar 22 along body 2 centers, and the two sides of described shelves bar 22 are extended first locating piece 221 and second locating piece 222 respectively; Form clamping part 201 between described first locating piece 221 and the cooling platform 21, described lampshade 1 edge is provided with and is provided with chimb 11, and described clamping part 201 is interlocked with the chimb 11 at lampshade 1 edge, and lampshade 1 is fixing.Form a mounting groove 202 between described second locating piece 222 and the cooling platform 21, described substrate protective sleeve 3 is strip, and its upper surface offers the installation position 31 of led light source substrate.Described substrate protective sleeve 3 can slip into or detach along mounting groove, and its bottom surface, side and mounting groove fit tightly, and is fixed by second locating piece 222.
Said structure reduces the screw position to greatest extent, makes the installation and removal of light fixture more convenient.Between the led light source substrate and substrate protective sleeve after the installation, scribble silica gel between substrate protective sleeve and the mounting groove, make it tight involution, the heat that makes led light source produce conducts to body by the substrate protective sleeve equably.
