Abstract

The utility model relates to an improved lamp which is mainly suitable for the design of the lamp socket aspect. The utility model mainly comprises a lamp socket with a radiating tube, a lamp cover covered on the lamp socket, a lamp shell covered under the lamp socket, and lamp tubes inserted in the lower part of the lamp socket, wherein a main lamp tube is suspended on the lamp socket; a gap exists between the contact surfaces of the lamp cover and the lamp socket; in addition, one air guiding hole is arranged on the lamp shell. Because of the arrangement of the air guiding hole, the radiating tube and the gap, air can generate convection, which causes internal temperature to descend; thereby, an electronic stabilizing device can be arranged in the lamp socket, which causes the lamp socket to have the advantages of light weight, electricity saving, no flicker, no noise, etc.

Description

The modified form light fixture

The utility model relates to a kind of modified form light fixture, and it mainly is in the mode of convection current the high temperature in the lamp socket to be distributed, and makes it the temperature reduction, but reaches the purpose of arranging electronic ballast.

In the market light fixture generally as shown in Figure 4, it mainly is made of lampshade 91, lamp socket 92, fluorescent tube 93, lamp housing 94; Wherein, lampshade 91 upper ends are provided with several louvres 911, and set firmly a lamp socket 92 for 91 times at lampshade, and on lamp socket 92, be provided with tradition such as inductance 921 and starter 922 starting elements, lamp socket 92 is arranged with tube face 923, rank is provided with fluorescent tube 93 in this tube face 923, and lamp housing 94 is to be installed in lampshade 91 times.

Existing lamp socket still can use, because of traditional inductance type bulb, its inductance element is not afraid of high temperature, it more is not subjected to Temperature Influence, but the effect that it also can't reach transient starting and improve power factor, with Japanese OSRAM label is example, its power factor is only about 0.6, about current sinking 0.28A, institute thinks and asks improvement, general light fixture mostly adopts electric ballast to replace inductance 921 and starter 922 now, to improve its power, reduce its current consumption and reach the purpose of transient starting, make this type of lamp socket reach power saving, flicker free phenomenon and noiseless user mode, but existing lamp socket can not be installed electric ballast, its reason be because fluorescent tube 93 and lamp socket 92 joint temperature up to 120 ℃, and lamp housing 94 seals this space fully, and cause temperature to distribute smoothly, high like this temperature just can conduct on the lamp socket 92, louvre 911 from lampshade 91 dispels the heat, but being not sufficient to make the temperature of lamp socket 92 upper surfaces to reduce to, this structure can install electric ballast, because of majority element in the electric ballast can't bear high temperature, for example the transistor in the electric ballast can not worked above under 100 ℃ the environment, the environment of the big pogoniasis of capacitor in the electric ballast under 85 ℃ could operate as normal again, because of traditional bulb is a hermetically-sealed construction, inside does not have cross-ventilation, only depend on hot-air to dispel the heat to the principle that rises, its radiating rate is quite slow, the operating temperature of its whole bulb can not be less than 90 ℃ usually, if electric ballast is installed in the bulb, its capacitor, transistor or the like electronic component just can be damaged in regular turn, cause the bulb can't operate as normal, and traditional lamp socket can't overcome the shortcoming that causes heat radiation to be difficult for because of structure, so can only adopt traditional startup original paper, can't substitute traditional startup original paper to reach the effect of low power consuming with electric ballast.

Also, reach the phenomenon generation that noise is arranged when starting so have fluorescent tube toggle speed flicker, Heavy Weight slow, that frequency is arranged because this type of lamp socket can only adopt traditional startup original paper.

Main purpose of the present utility model is to provide a kind of modified form light fixture, its lamp socket is provided with radiating tube, and cooperate the king light pipe to be hung on the heat that makes on the lamp socket in the lamp housing to arrive in the lampshade fast, gap heat radiation from lampshade and lamp socket, and owing on lamp housing, offer a gas port, in lamp socket, produce convection current its temperature inside is reduced fast, so just can arranging electronic ballast on the lamp socket, make this type of light fixture reach in light weight, power saving, flicker free phenomenon and noiseless purpose.

The technical solution of the utility model is to provide a kind of modified form light fixture, it mainly is to be made of lampshade, lamp socket, fluorescent tube, lamp housing, wherein, the lampshade upper end is provided with an outer joint chair, and lampshade upper limb week side be provided with louvre, this lampshade lower edge is provided with a lamp socket, and is covered with a lamp housing and establishes fluorescent tube at the lamp socket downlink under lamp socket, it is characterized in that:
