Abstract

The utility model provides an LED fluorescent lamp with 360-degree illumination without blind angles. The LED fluorescent lamp solves the problem that most of existing LED fluorescent lamps cannot achieve 360-degree illumination. The LED fluorescent lamp comprises a lampshade, end caps installed at the ends of the lampshade, a substrate installed in the lampshade and LED surface-mounted devices (SMDs). Four LED SMDs are arranged in each set, and the four LED SMDs in each set are arranged on four faces of the substrate in parallel respectively and are located on the same tangent plane; then, the sets of LED SMDs are connected in series. Through the structure, it can be guaranteed that the lamp tube can emit light all around, and the light source will not have blind angles; cooling fins are arranged in the tubular substrate, heat can be effectively dissipated by using the cooling fins and a special base in cooperation, and the service life of the whole fluorescent lamp is guaranteed; due to the structure that the sets of LED SMDs are connected in series and the LED SMDs in each set are connected in parallel, if one part of the lamp has a problem in the using process, the other parts can still work well, and the overall illumination effect will not be influenced.

Description

LED fluorescent lamp

Technical field

The utility model relates to field of illuminating lamps, is that a kind of 360 degree are without the LED fluorescent lamp of blind spot lighting specifically.

Background technology

LED fluorescent lamp is a kind of light low, good illumination effect that consumes energy rising in recent years, and it reaches 50% left and right than traditional daylight lamp energy-saving, and also better than traditional fluorescent lamp effect aspect brightness.Existing LED fluorescent lamp easily produces amount of heat in the process of using, and distributes when not going out and will cause lamp pearly-lustre to decline, and then affect the service life of light fixture when heat build-up; And it is semicircle that the lampshade of existing LED fluorescent lamp mostly is, the place that needs 360 degree illuminations at some, this LED fluorescent lamp can not well open the effect of illumination.

Summary of the invention

The purpose of this utility model is to provide a kind of 360 degree without the LED fluorescent lamp of blind spot lighting, and solving existing most of LED fluorescent lamps can not 360 problem of throwing light on.

The utility model is realized above-mentioned purpose by the following technical solutions:

LED fluorescent lamp comprises lampshade, be contained in the plug of lampshade end, be contained in substrate, the LED paster of lampshade inside.

Described lampshade is cylindric, on the inner surface of lampshade, is provided with striped; Described substrate is square tubulose, and described LED paster is contained on the outer surface of tubular substrate, and the substrate inner surface of described tubulose is provided with the fin of strip; Described plug is tubular, at the bottom centre place of plug, is provided with square opening, and the inside of square opening is provided with rectangular tube, and described rectangular tube can insert the inside of tubular substrate, in plug bottom outside, is provided with two contacts.

Preferably, the mounting means of described LED paster is: every group of LED paster is provided with four, and these four LED pasters are in parallel being located on four faces of substrate respectively, and these four LED pasters are positioned on same tangent plane; Then many group LED pasters series connection.

Preferably, on the inner surface of the substrate of described square tubulose, each face is provided with vertically parallel equally distributed fin.

The utility model adopts said structure can guarantee that the surrounding of fluorescent tube all has light, there will not be light source dead angle, and the substrate inside of tubulose arranges fin, can effectively dispel the heat with the special-purpose common use of base, has guaranteed whole service life; The grouping series connection of LED paster, in group, structure in parallel can make the lamp work that in use certain section of other part while going wrong still can be intact, can not affect whole illuminating effect.

Accompanying drawing explanation

Fig. 1 and Fig. 2 are schematic diagram of the present utility model.

Fig. 3 is cutaway view of the present utility model.

Fig. 4 is the schematic diagram of LED paster mounting structure on substrate.

The specific embodiment

Below in conjunction with accompanying drawing, the utility model is further described.

LED fluorescent lamp as depicted in figs. 1 and 2 comprises lampshade 1, be contained in the plug 2 of lampshade 1 end, be contained in substrate 3, the LED paster 4 of lampshade 1 inside.

Lampshade 1 is as shown in Figure 3 cylindric, on the inner surface of lampshade 1, is provided with striped; Described substrate 3 is square tubulose, and described LED paster 4 is contained on the outer surface of tubular substrate 3, and substrate 3 inner surfaces of described tubulose are provided with the fin 5 of strip, and fin 5 is even parallel arrangement on each face of the inner surface of substrate 3; Described plug 2 is tubular, at the bottom centre place of plug 2, is provided with square opening, and the inside of square opening is provided with rectangular tube 6, and described rectangular tube 6 can insert the inside of tubular substrate 3, in plug 2 bottom outside, is provided with two contacts 7.

The mounting means of LED paster 4 is as shown in Figure 4: every group of LED paster 4 is provided with four, and these four LED pasters 4 are in parallel being located on four faces of substrate respectively, and these four LED pasters 4 are positioned on same tangent plane; Then many group LED pasters 4 series connection.

In the process of using, the utility model can be realized required effect with the corresponding common use of base.
