Abstract
The utility model solves the technical problem that a conventional LED fluorescent lamp is poor in heat dissipation performance, short in service lifetime and high in fault rate. In order to solve the problem, a cylindrical LED fluorescent lamp is provided including a lampshade and an LED lamp bead installed on a substrate. The substrate installed on the lamp top, and the lampshade and the lamp top form a cylindrical tube. Heat-radiation through holes are distributed on the lamp top. Compared with a conventional LED fluorescent lamp, heat-radiation through holes arranged in the lamp top accelerates air flow in the cavity between the lamp top and the substrate, rapidly takes heat away and accelerates heat radiation speed, thereby improving the integral heat radiation performance, preventing fault and prolonging service lifetime.
Description
Technical field
The utility model relates to a kind of LED lamp, is specifically related to a kind of cylindrical LED fluorescent lamp.
Background technology
Due to LED streetlamp energy-saving, long service life, it is widely used at lighting field.Because LED fluorescent lamp volume is little, not enough aspect heat radiation, because heat radiation is bad, cause LED fluorescent lamp Frequent Troubles, and shorten its service life.
Summary of the invention
The technical problems to be solved in the utility model is that existing LED fluorescent lamp heat radiation performance is bad, and service life is short, and fault rate is high, for addressing the above problem, provides a kind of cylindrical LED fluorescent lamp.
The purpose of this utility model realizes in the following manner:
Cylindrical LED fluorescent lamp, comprises lampshade and is arranged on the LED lamp pearl on substrate, it is upper that described substrate is arranged on lamp top, and lampshade and a cylindrical tube of lamp top formation; Lamp is distributed with heat radiation through hole on top.
Described substrate is V-type, and V-type substrate is by two swash plates for mounted LED lamp bulb and form in conjunction with limit, and faces in conjunction with limit and arc lampshade.
The V-type substrate that described substrate is formed in one.
Described substrate is the V-type substrate that two swash plates are spliced.
The side of described V-type substrate two swash plates is combined with lamp top, between lamp top and substrate, forms cavity.
Described lamp top is section bar lamp top.
With respect to prior art, the utility model relatively with existing LED fluorescent lamp, on lamp top, heat radiation through hole is set, by heat radiation through hole, Air Flow in the cavity between lamp top and substrate is accelerated, can fast heat be taken away, accelerate radiating rate, make whole raising of heat dispersion of lamp, avoid breaking down, increase service life.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
The specific embodiment
As shown in Figure 1, cylindrical LED fluorescent lamp, comprises lampshade 1 and is arranged on the LED lamp pearl 3 on substrate 2, substrate 2 is arranged on lamp top 4, and lampshade and a cylindrical tube of lamp top formation; On lamp top, be distributed with heat radiation through hole 5.
Substrate 2 is V-type, and V-type substrate is by two swash plates 21 for mounted LED lamp bulb and form in conjunction with limit 22, and faces in conjunction with limit and arc lampshade.Substrate is arranged to V-type, can makes the lighting angle of LED lamp pearl on substrate be greater than 180o, increased the irradiating angle of whole LED lamp pearl, the scope that can irradiate strengthens.
According to different needs, substrate can be made of one to the V-type substrate of moulding, or be spliced by two swash plates.
The side of V-type substrate two swash plates is combined with lamp top, between lamp top and substrate, forms cavity.Make substrate and lamp top contact, can accelerate the conduction of heat, make its heat dispersion better.For convenient batch production, save production cost, forming material lamp top is done in lamp top.
