Abstract
The utility model aims to provide an LED fluorescent lamp good in heat dissipation in order to solve the problem that an exiting LED fluorescent lamp is poor in heat dissipation. The LED fluorescent lamp comprises a semicircular base, a semicircular lampshade, a plate-shaped substrate and chip LEDs. According to the LED fluorescent lamp good in heat dissipation, 40 bunches of four parallel lamp beads are connected, it is guaranteed that after any of every four lamp beads connected in parallel goes wrong, the other three lamp beads can emit light normally, the illuminating effect of the whole lamp can be guaranteed, the 40 bunches of lamp beads work under high voltage and low current, the power source efficiency can be improved due to the high voltage and the lower current, and the luminous efficiency of the whole lamp can be improved; the heat dissipation effect can be guaranteed due to the adoption of a through groove and cooling fins, and the service life of the lamp is effectively prolonged.
Description
Technical field
The utility model belongs to field of light fittings, is a kind of LED fluorescent lamp 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.
Summary of the invention
The utility model aims to provide a kind of LED fluorescent lamp that dispels the heat good, solves the bad problem of heat radiation that existing LED fluorescent lamp exists.
The utility model is achieved through the following technical solutions above-mentioned purpose:
A kind of LED fluorescent lamp comprises semicircular pedestal, semicircular lampshade, tabular substrate, LED paster.The inside of the both sides of described semicircular lampshade is provided with bar shaped projection, on described pedestal, on the face relative with lampshade, is connected with two fasteners, and the both sides of fastener are equipped with groove, and above-mentioned bar shaped projection is corresponding with the groove of arranged outside on fastener; Described substrate is fastened in the groove of fastener inner side setting; Described LED paster is fitted on above-mentioned substrate.
The bottom of described half circular base is provided with the groove of arch, is connected with the radiating fin of parallel distribution on the top of arch groove.
Preferably, described LED paster is provided with 160 altogether, adopts the connected mode of 4 and 40 strings.
Preferably, the space between described radiating fin is 1.5 times of radiating fin thickness.
When the connected modes of the utility model employing 4 and 40 strings can guarantee that arbitrary in 4 lamp pearls in parallel goes wrong, its excess-three can be normally luminous, guarantee the illuminating effect of whole lamp, and 40 strings are high voltage low current modes, high voltage low current can improve power-efficient, improves whole light effect; The structure that adopts groove to add radiating fin can guarantee the effect of heat radiation, has effectively extended the service life of light fixture.
Accompanying drawing explanation
Fig. 1 is schematic diagram of the present utility model.
Fig. 2 is the structural representation of substrate and LED paster.
The specific embodiment
Below in conjunction with accompanying drawing, the utility model is further described.
A kind of LED fluorescent lamp as shown in Figure 1 comprises pedestal 1, lampshade 2, substrate 3, LED paster 4.Pedestal 1 and lampshade 2 are half round post, and the inside of lampshade 2 both sides is provided with bar shaped projection 21, on pedestal 1, on the face relative with lampshade 2, are connected with two fasteners 5, and the both sides of fastener are equipped with groove; Above-mentioned bar shaped projection 21 can be fastened in the groove of arranged outside on fastener 5, and substrate 3 is fastened in the groove of fastener 5 inner sides settings.
The bottom of pedestal 1 is provided with the groove 11 of arch, is connected with the radiating fin 12 of parallel distribution on the top of groove 11; Space between radiating fin 12 is 1.5 times of itself thickness.
Be illustrated in figure 2 the mounting means of LED paster 4 on substrate 3, LED paster 4 is provided with 160 altogether, adopts the connected mode of 4 and 40 strings.
