Abstract

The utility model relates to an improved structure of energy-saving tubular lamp in the technical field of lighting facilities. The lamp consists of a barrel, a lamp cup fixed inside the barrel and a tube fixed inside the lamp cup. The tube is a fluorescent tube and the barrel consists of an opening and a body. The upper end of the barrel opening is provided with a stopping piece and the lower end is inserted into the upper end of the barrel body. The upper end of the barrel body transits to the barrel handle by a bottleneck. The bulb holder is fixed on the lower end of the barrel handle. The bottleneck of the barrel body is provided with fixing seat for circuit board and the fixing seat is provided with the lamp cup of the fluorescent tube on the upper portion and the ballast circuit board of the barrel handle on the lower portion. Fluorescent tubes are low-power and high-brightness which realize the effect of saving energy. The utility model is reasonable in structure and the tube and the circuit board are arranged in the barrel body which makes the utility model compact and easy to shape and assemble.

Description

Energy-conserving barrel lamp

Technical field

The utility model relates to a kind of lighting device, and especially a kind of architecture advances of energy-conserving barrel lamp belongs to the lighting installation technical field.

Background technology

Cold light source is very little to ambient temperature effect, therefore is applied in many occasions.Understand according to the applicant, the existing Down lamp of cold light source that adopts adopts quartz-iodine lamp substantially, because the design of the selection of fluorescent tube and cylindrical shell is unreasonable, therefore has the shortcoming that energy consumption is big, color is single, and can't containment circuit board etc. member.

The utility model content

The purpose of this utility model is: at the shortcoming that above prior art exists, propose a kind of energy, compact conformation, energy-conserving barrel lamp easy to assembly saved.

In order to reach above purpose, energy-conserving barrel lamp of the present utility model comprises cylindrical shell, be fixed on Lamp cup in the cylindrical shell, be placed in the fluorescent tube in the Lamp cup, it is characterized in that: described fluorescent tube is a fluorescent tube, described cylindrical shell is made of nozzle and stack shell, described nozzle upper end is shaped on seam, the lower end is inserted in the stack shell upper end, the tube handle is excessively arrived by necking down in the stack shell upper end, tube handle lower end is lamp holder fixedly, the bottleneck of described stack shell is settled the circuit board holder, settle the Lamp cup that fluorescent tube is housed on the holder, be fixed in the ballasting circuit plate of a handle below.

Because fluorescent lamp has the characteristic of low-power, high brightness, therefore has desirable energy-saving effect.And the utility model reasonable structural design all is dissolved among the cylindrical shell fluorescent tube, circuit board, so compact conformation, and moulding, easy row simple for assembly process.

Description of drawings

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

Fig. 1 is the structural representation of the utility model embodiment one.

Fig. 2 is the structural representation of the utility model embodiment two.

The specific embodiment

Embodiment one

The energy-conserving barrel lamp of present embodiment mainly is made up of socket lamp holder 7, ballasting circuit plate 6, circuit board holder 5, aluminium matter nickel plating Lamp cup 4, stack shell 3, nozzle 2 as shown in Figure 1.

The upper end of nozzle 2 is shaped on seam, and just in time card is pushed down fluorescent tube Lamp cup 4 upper port glass lamp shades 1 are housed, and it is step-like to contract in make the lower end, and the internal diameter of external diameter and stack shell 3 upper ends matches, and is inserted in stack shell 3 upper ends, not only made things convenient for assembling, and profile is carefully and neatly done.The tube handle is excessively arrived by necking down in the upper end of stack shell 3, and tube handle lower end is socket lamp holder 7 fixedly, and the lamp holder of these lamp holder both sides rolls 8 and constitutes outlet structure.The bottleneck of stack shell 3 is settled circuit board holder 5, settles the Lamp cup 4 that fluorescent tube is housed on the seat, is fixed in the vertical ballasting circuit plate 6 of a handle below.Ballasting circuit on the ballasting circuit plate is identical with the ballasting circuit of existing fluorescent lamp, adopts paster technique to make, and is therefore very compact.

The energy-conserving barrel lamp of present embodiment has been realized fluorescent tube, circuit board all are dissolved in wherein Rational structure design, has compact conformation, advantage easy to assembly.The brightness (600lx) that experiment showed, 6W is equivalent to existing 50W halogen cold light lamp brightness (500lx), and is therefore very energy-conservation.

Embodiment two

The basic structure of present embodiment is identical with embodiment one, difference is the shank lower end assembling screw socket 7 of stack shell 3, the screw thread conducting position employing of this lamp holder is moulded core and is coated crome metal electrodeposited coating structure outward, has good, the not easy rusting bad advantage of deteriorating of conductive effect.

In addition to the implementation, the utility model can also have other embodiments.All employings are equal to the technical scheme of replacement or equivalent transformation formation, all drop on the protection domain of the utility model requirement.
