Abstract
The utility model discloses a light-emitting diode (LED) glass tube which comprises a hollow cylindrical tube body. A section of the inner wall of the tube body is composed of an arc side and a right-angle side. The LED glass tube with an irregular ring-shaped section takes a plane formed by straight edges as a heat dissipation surface to improve a heat dissipation structure. An LED lamp panel is pasted on a glass wall directly. A cooling part can reduce a plurality of layers of conduction structures and is directly fixed on the heat dissipation surface of the LED glass tube. Heat dissipation aluminum bars are saved, so that not only is material saved, but also heat dissipation rate can be improved.
Description
Technical field
The utility model relates to field of semiconductor illumination, particularly relates to a kind of LED glass lamp.
Background technology
Vitals as the LED fluorescent tube---glass lamp, it can produce heat in the course of the work, such as untimely heat radiation, will burn out whole LED fluorescent tube.Traditional glass lamp is circular cross-section, and inner surface has radian, and the heat of LED lamp plate must through a heat radiation aluminum strip, just can be transitioned into the glass tube walls of cambered surface, thereby heat is taken away.Obviously, guaranteeing under the prerequisite that good heat radiating transmits that the imagination aluminum strip that will dispel the heat removes, and can either alleviate the weight of LED fluorescent tube, can save manufacturing cost again, will be the technological progress that kills two birds with one stone.
The utility model content
The utility model provides a kind of LED glass lamp of direct contact heat radiation transmission for the problem that prior art exists.
In order to solve the problems of the technologies described above, the utility model is achieved by following technical scheme: a kind of LED glass lamp, comprise the cylindrical tube of hollow, and the cross section of inboard wall of tube body is made of arc-shaped edges and right-angle side.
Further, the wall thickness of described body is 0.8～1.2 millimeter, and the radius of arc-shaped edges is 12～12.5 millimeters, and arc chord angle is 290～300 degree.
Compared with prior art, the beneficial effects of the utility model are: the LED glass lamp that adopts irregular circular ring section, utilize the plane of straight flange shaping as radiating surface, enlarge active surface improves radiator structure, and the LED lamp plate directly is affixed on glass wall, and heat radiation part can reduce by some layers of conducting structure, be directly fixed on LED glass tube radiating surface, saved the heat radiation aluminum strip, not only saved material but also can heat radiation speed.
Description of drawings
Fig. 1 is the perspective view of LED glass lamp.
Below, with specific embodiments and the drawings further is described in detail the utility model.
The specific embodiment
As shown in Figure 1, the LED glass lamp, the cross section of the cylindrical tube inwall of its hollow is made of arc-shaped edges 1 and right-angle side 2, and the cross section stretches behind vertical certain-length, becomes three-dimensional body.The wall thickness of body is 1 millimeter, and the radius of arc-shaped edges is that R12.25 millimeter and arc chord angle a are 300 degree.
Claims (3)
1. LED glass lamp comprises the cylindrical tube of hollow, and it is characterized in that: the cross section of described inboard wall of tube body is made of arc-shaped edges and right-angle side.
2. LED glass lamp according to claim 1 is characterized in that, the radius of described arc-shaped edges is 12～12.5 millimeters, and arc chord angle is 290～300 degree.
