Abstract
The utility model discloses a fixing structure for a light-emitting diode (LED) chip board of a light-emitting diode (LED) lamp tube, which comprises a supporting piece, a lamp shade fixed with the supporting piece, the LED chip board arranged between the supporting piece and the lamp shade, and end covers covered at axial ends of the supporting piece and the lamp shade, the supporting piece is provided with a containing groove arranged along the axial direction, the LED chip board is arranged in the containing groove, the inner sides of the end covers are provided with propping structures that prop against the outer surface of the LED chip board positioned at the notch side of the containing groove. The LED chip board is convenient in installation, and closely attached to the supporting piece, so as to be beneficial to heat conduction, and prolong the service life of the lamp tube.
Description
Technical field
The utility model relates to a kind of led chip board fixing structure of LED fluorescent tube.
Background technology
LED in the prior art (light emitting diode) fluorescent tube generally comprises support member, be fixed on led chip plate on the support member, fix and cover at the outer lampshade of led chip plate with support member, wherein support member and lampshade two end cap are provided with end cap, make the led chip plate be positioned at the airtight substantially space that is made of support member, lampshade and end cap.In the prior art, the led chip plate generally is fixed on the support member by connectors such as screws, and its assembling is cumbersome, influences production efficiency.
Summary of the invention
The utility model purpose is: a kind of led chip board fixing structure of LED fluorescent tube is provided, and its led chip plate easy for installation, and led chip plate and support member fit closely, helps the heat conduction, the service life of prolonging lamp tube.
The technical solution of the utility model is: a kind of led chip board fixing structure of LED fluorescent tube, comprise support member, and the fixing lampshade of support member, be fixed on the end cap that led chip plate between support member and the lampshade and lid are located at support member and lampshade axial end portion, described support member is provided with the storage tank of arranging vertically, described led chip plate is located in the described storage tank, the inboard of described end cap is provided with abutting structure, and described abutting structure supports to be located on the outer surface of notch side that described led chip plate is positioned at storage tank.
Further, in the said fixing structure, described support member is the metal heat-conducting material, and as the aluminium extruded support member, the led chip plate fits tightly on support surface under the effect of abutting structure, play the effect of firm fixation on the one hand, on the other hand, because the contact-making surface of led chip plate and support member is bigger, so the heat on the convenient led chip plate is transmitted on the support member, distribute the service life of prolonging lamp tube again.
Further, in the said fixing structure, the end face that described end cap comprises periphery wall and is connected the periphery wall axial outer end, described abutting structure is located at the inboard of described end face axial.
Further, in the said fixing structure, described support member radially is provided with vertically the support plate portion that distributes in the centre position in fluorescent tube, and described storage tank is located at a side of described support plate portion.The led chip integrated circuit board inserts in the described storage tank.
Further, in the said fixing structure, also be provided with draw-in groove in axial end portion in the described support plate portion, also be provided with the grab with the corresponding buckle of draw-in groove on the described end cap, described grab and abutting structure fit in the opposite side of described support plate portion on the contrary.Grab cooperates with draw-in groove on the one hand, plays the end cap fixation, and on the other hand, itself and abutting structure are located in the both sides of support plate portion and led chip plate respectively, avoids support plate portion and chip board one-sided stressed and be out of shape.
The utility model has the advantages that:
1. the utility model led chip plate is easy for installation, and led chip plate and support member fit closely, helps the heat conduction, the service life of prolonging lamp tube.
