CN2283309Y - Rare earth three primary colour fluorescent lamp - Google Patents

Abstract

The utility model discloses a fluorescent lamp with rare earth three primary colors, which is composed of a strip lamp, a lamp holder, and a lamp cap, wherein, a ballast is arranged inside the lamp holder, and a PTC element inside a top heat circuit of a ballast filament is arranged outside the lamp holder and is positioned between two lamp feet of the strip lamp. Because the local temperature at the point of the two lamp feet is as high as 120 DEG after the strip lamp is conducted, the PTC element can adsorb the part of heat quantity and can reduce electric current which is required for maintaining the rated temperature. Thus, the power consumption of the PTC element can be reduced further. According to a test, the power consumption of PTC element is only 60 percent of the original power consumption after a technology is adopted.

Description

The rare-earth trichromatic fluorescent lamp

The utility model relates to a kind of rare-earth trichromatic fluorescent lamp.

The rare-earth trichromatic fluorescent lamp is made up of fluorescent tube, lamp socket and lamp holder, has compact conformation, energy-efficient characteristics are equipped with ballast in its lamp socket, at present, the filament preheating circuit of ballast has generally adopted the PTC element, this PTC element still need be switched on and keep that it is hot after the fluorescent tube conducting, still needs consumed power in other words, concerning 5 watts-24 watts fluorescent tube, the power consumption of PTC element approximately is the 10-3% of power of lamp tube.

The purpose of this utility model provides a kind of rare-earth trichromatic fluorescent lamp that can further reduce PTC element power consumption.

It is outside and between two lamp bases of fluorescent tube that solution of the present utility model is that the PTC element is arranged on lamp socket.

After the fluorescent tube conducting of rare-earth trichromatic fluorescent lamp, the local temperature at fluorescent tube two lamp base places is up to 120 ℃, after moving on to the PTC element herein, the PTC element can absorb this part heat, thereby can reduce and keep the required electric current of its rated temperature, and power consumption can further reduce like this, according to test, 5 watts-24 watts fluorescent tube, adopted present technique after, the power consumption of PTC element only is 60% of a former power consumption.

Illustrate particular content of the present utility model below in conjunction with drawings and Examples.

Accompanying drawing is a structure chart of the present utility model.

As shown in the figure, rare-earth trichromatic fluorescent lamp described in the utility model is made up of fluorescent tube 1, lamp socket 2 and lamp holder 3, wherein in the lamp socket 2 ballast 4 is housed, the utility model is arranged on the outside of lamp socket 2 with the PTC element in the filament preheating circuit of ballast 4 and between two lamp bases 5,6 of fluorescent tube 1.The present technique solution all is suitable for U type fluorescent tube and H type fluorescent tube.

Claims (1)

1, a kind of rare-earth trichromatic fluorescent lamp, form by fluorescent tube, lamp socket and lamp holder, wherein in the lamp socket ballast is housed, it is characterized in that: the PTC element in the filament preheating circuit of ballast (4) is arranged on the outside of lamp socket (2) and is positioned between two lamp bases (5,6) of fluorescent tube (1).
