Description
Technical field
The utility model relates to the LED tube lamp.
Background technology
Because LED has advantages such as light efficiency height, rich color, life-span be long, in every field, to the application of LED more and more widely, particularly in stage, view, certain, in daily illumination, the LED lamp is also at gradually alternative traditional light fixture, particularly LED fluorescent tube.
As being to be that open day of 2011.8.6 discloses a kind of LED fluorescent tube in the patent documentation of 2012.2.1 201110228909.4 applyings date at application number, specifically disclose it and comprised lampshade, the carrying lamp plate, driving power, lamp socket, left end cap and right end cap, lampshade and lamp socket semicircular in shape, be provided with overhead kick at the lampshade inwall, be provided with the draw-in groove I at inboard wall of lamp holder, the draw-in groove II, the draw-in groove III, overhead kick embeds into, and the draw-in groove II makes lampshade and lamp socket be fastenedly connected the formation round lamp tube each other, form accommodation space at the round lamp tube endoporus, in accommodation space, be provided with carrying lamp plate and driving power, the holding of carrying lamp plate is on the draw-in groove I, the lamp pearl is installed on the carrying lamp plate, in this structure, the carrying lamp plate can be equivalent to substrate, and left end cap and right end cap embed the into inwall of lamp tube ends.The defective of this LED fluorescent tube is: the installation to the carrying lamp plate must need arrange draw-in groove, but when making the carrying lamp plate, if the width of carrying lamp plate is too wide too thick, then can't be inserted in the draw-in groove, if the carrying lamp plate is too narrow and too thin, then carry lamp plate be installed to have in the draw-in groove back both have the gap, the carrying lamp plate can rock in draw-in groove, if the width of carrying lamp plate is less than the spacing between two draw-in grooves, then the carrying lamp plate can't be installed, therefore, the width of carrying lamp plate and the restriction that thickness is subjected to draw-in groove; And when carrying lamp plate and draw-in groove have the gap, then carrying lamp plate can not closely contact with lamp socket, and carrying equals also little with the contact area of lamp socket, then the transmission of heat is restricted, and like this, the part heat on the carrying lamp plate can be by transfer of air to lamp socket, then, through the lamp socket dissipated heat, thereby lower the speed that heat scatters and disappears, caused radiating effect bad.
As not adopting fixedly lamp plate of draw-in groove mode, fix and use screw instead, then because the material thickness of lamp socket influences, in most cases the lamp socket thinner thickness is difficult for fixing.
Summary of the invention
The fixed structure that the purpose of this utility model provides a kind of LED tube lamp substrate utilizes structure of the present utility model, can improve radiating effect, is convenient to mount and dismount substrate, reduces the production cost of LED tube lamp.
For achieving the above object, a kind of fixed structure of LED tube lamp substrate comprises lamp body and substrate, it is characterized in that: lamp body is provided with first installing hole, substrate is provided with second installing hole, and first installing hole and second installing hole have passed buckle, and buckle is fixed to substrate on the lamp body.
Said structure, because substrate is to pass first installing hole, second installing hole by buckle to be connected on the base plate carrying plate, like this, under the effect of buckle, with substrate and lamp body fitting together tightly.By above-mentioned fixed structure, substrate and lamp body are tightly fitted, and both contacts area are big, can improve the reliability of heat transfer and the speed of heat transfer, make the most of heat on the substrate to be delivered on the lamp body outer surface by lamp body, therefore, good heat dissipation effect.With respect to prior art, owing to do not need draw-in groove to fix substrate, therefore, the width of substrate and thickness are not limited by draw-in groove, can like this, can reduce the cost of substrate according to the Demand Design substrate of led light source.In addition, therefore substrate fixed by snap, is convenient to mount and dismount substrate.
As specializing, described lamp body comprises radiating shell and base plate carrying plate, and first installing hole is located on the base plate carrying plate.
As improvement, the elastic portion more than two that described buckle comprises body, extend downwards from the blocking part more than two that body extends laterally, from body and be connected insertion section on the elastic portion has outside projection on the insertion section; Described elastic portion is passed first installing hole and second installing hole; Described blocking part is positioned at the top of substrate and contacts with substrate, and elastic portion is passed substrate and base plate carrying plate, and described projection is positioned at the below of base plate carrying plate, and projection contacts with the base plate carrying plate.This structure, because buckle has blocking part, elastic portion and insertion section, buckle during insertion, pass second installing hole of substrate and first installing hole of base plate carrying plate by the insertion section, elastic portion deforms simultaneously, when the projection of insertion section is positioned at the below of base plate carrying plate, elastic portion resets, blocking part and substrate contacts, like this, under projection and the effect of blocking part, with substrate and base plate carrying plate fitting together tightly, with the connection reliability of raising substrate and base plate carrying plate, and be convenient to mount and dismount substrate.
As specializing, described blocking part comprises the stretch section that is connected with body and the projection of keeping out that is connected on the stretch section.Have a stretch section on the described blocking part, can allow and keep out projection strain and screen resilience take place, make keep out projection and substrate contacts get more tight, thereby it is more tight that substrate contact with the base plate carrying plate, with the raising radiating effect.
As improvement; described buckle is non-conductive Elastic buckle; it is tightr that the elastically-deformable restoring force of buckle makes substrate contact with the base plate carrying plate, and non-conductive Elastic buckle guarantees that substrate contacts with the non-conductive of base plate carrying plate, avoids the electric leakage of lamp body surface leakage.
