Abstract
The utility model relates to a kind of LED lamp tube shell, comprise lighttight housing and the lampshade being located at the printing opacity on housing, two parallel gathering sills are arranged with at housing and the junction inwall of lampshade, the pcb board two edges being fixed with LED are stuck in gathering sill, and described housing and lampshade are the integral structure of single injection-molded; Gathering sill is formed by two parallel retaining rail; The width of rebate of gathering sill and pcb board edge matching; The section of lampshade is circular square semicircle or oval.LED lamp tube of the present utility model is provided with pcb board gathering sill, facilitates LED freely to install, and housing integration structure is simple, and heat radiation translucent effect is good, extends LED service life.
Description
Technical field
The utility model relates to LED technical field, and especially relating to LED is a kind of LED lamp tube shell of light source.
Background technology
LED, as emerging third generation light source, has the advantage of the aspects such as energy-saving and environmental protection, and just progressively development replaces conventional light source incandescent lamp and second generation electricity-saving lamp.LED needs LED lamp tube shell to assist to solve the printing opacity of LED, heat radiation, installation and protection problem, and at present, existing LED shell still exists following problem: assembling is complicated; production cost is high; in the process used, tube housing easily breaks, and uses inconvenience.
Utility model content
In view of this, the utility model, for solving the problems of the technologies described above, provides one to facilitate a kind of LED lamp tube shell of LED freely fitted.
The purpose of this utility model is achieved through the following technical solutions:
A kind of LED lamp tube shell, comprise lighttight housing and the lampshade being located at the printing opacity on housing, two parallel gathering sills are arranged with at housing and the junction inwall of lampshade, the both sides of the edge being fixed with the pcb board of LED are fastened in gathering sill, and described housing and lampshade are the integral structure of single injection-molded.
Wherein, described gathering sill is formed by two parallel retaining rail.
Wherein, the width of rebate of described gathering sill and pcb board edge matching.
Further, the section of described lampshade is circular square semicircle or oval.
Further, described case top is provided with reinforcement.
The utility model compared to the beneficial effect of prior art is:
The gathering sill that tube housing is arranged facilitates LED freely to install, and this tube housing protects LED very well, effectively can promote the service life of LED, and the utility model tube housing heat radiation printing opacity.
Accompanying drawing explanation
The utility model is described in further detail to utilize accompanying drawing, but the embodiment in accompanying drawing is not formed any restriction of the present utility model.
Fig. 1 is the schematic cross-section of a kind of LED lamp tube shell of embodiment of the present utility model.
Fig. 2 is the tomograph of a kind of LED lamp tube shell of embodiment of the present utility model.
Detailed description of the invention
The utility model to be described in further detail below in conjunction with accompanying drawing and embodiment for the ease of it will be appreciated by those skilled in the art that.
Please refer to Fig. 1-2, the utility model embodiment comprises:
A kind of LED lamp tube shell, comprises lighttight housing 2 and the lampshade 1 being located at the printing opacity on housing, and the section of lampshade 1 is circular; Be arranged with two parallel gathering sills 3 at housing 2 and the junction inwall of lampshade, gathering sill 3 is formed by two parallel retaining rail, and the pcb board two edges being fixed with LED are stuck in gathering sill 3, the width of rebate of gathering sill 3 and pcb board edge matching.
Housing 2 is light-proof material, and lampshade 1 is light transmissive material, and housing 2 and lampshade 1 are the integral structure of single injection-molded.
Wherein, use the injection molding process of the integral structure of double-colored single injection-molded to be: matched moulds, die cavity cuts off by separator; Inject the first material; Inject the second material again; Close the first injection port; Again separator is stepped back; Close the second injection port and complete cooling pressurize after die sinking eject plastic.Or at the first material of injection through cooling pressurize backed off after random separator, then carry out the injection of the second material.
Further, housing 2 top is provided with two reinforcements be parallel to each other 4.Characteristic due to fluorescent tube self determines its needs and works long hours, and easily because work long hours and case top generation local sag bent; The sag bent of case top easily betides the central area of case top, be provided with two reinforcements in the case top of the present embodiment for this reason, guarantee that the phenomenon of sag bent can not occur in case top central area, ensure that the overall structure of tube housing has sufficiently high intensity.In addition, because case top fits tightly the integral installation that realizes tube housing, set up reinforcement in case top, make to leave space between case top and installed surface, contribute to strengthening thermal convection current, improve the radiating efficiency of fluorescent tube.
Be more than specific implementation of the present utility model, it describes comparatively concrete and detailed, but therefore can not be interpreted as the restriction to the utility model the scope of the claims.It should be noted that; for the person of ordinary skill of the art; without departing from the concept of the premise utility; some distortion and improvement can also be made; it is semicircle or oval that the section of LED lamp tube shell also can be designed as square, and these apparent replacement forms all belong to protection domain of the present utility model.
