Abstract
The utility model relates to a portable lamp belonging to the technical field of the low-pressure gas electricity discharging light source and is composed of a light source body, a transparent cover, an upper end cap, a lower end cap and a power plugging head. The portable lamp is characterized in that the light source body is composed of a single-end fluorescent lamp pipe with the 6-10 mm diameter. The middle part of the single-end fluorescent lamp pipe is curved, and the straight pipe parts of the single-end fluorescent lamp pipe are parallel. Both ends of the single-end fluorescent lamp pipe are sealed and are respectively provided with electrodes. A half-bridge inversion electronic ballast is arranged in the lower end cap, and the output end of the half-bridge inversion electronic ballast is electrically connected with the single-end fluorescent lamp pipe. The portable lamp is widely used for the illumination of the machine maintenance, the field tour, the garden and the road and has the advantages of high luminous efficiency and long service life.
Description
The utility model belongs to the glow discharge spot lamp technical field, relates to the lantern that ballast is housed.
Usually the employed lantern of people has two kinds: a kind of is the incandescent lamp of band metal guard, and another kind is the utility light that adopts fluorescent tube.Owing to the former power attenuation meets with greatly eliminating, the latter's fluorescent tube adopts both-end YZ8RR type, caliber slightly reaches 16mm, electric current is big so lamp works voltage is low, and the version that the ballast that matches adopts resistor-capacitor to contact mutually, though it is little to have a volume, the advantage that cost is low, it is serious that but resistor is operated under the big current situation heating loss, and the surge current that capacitor produces also will cause double-end fluorescent tube cathode sputter aggravation and blackout is aging too early.Therefore, its luminous efficiency shortcoming low, that working life is short is conspicuous.
The purpose of this utility model is to design the lantern of a kind of luminous efficiency height, long working life.
For achieving the above object, design main points of the present utility model are to be made of light source body, translucent cover, upper end cover, bottom end cover and attaching plug, it is characterized in that described light source body is that one end fluorescent lamp pipe by diameter 6-10mm constitutes, its middle part bending, and straight-tube portion is parallel to each other, and is sealed at both ends and respectively put an electrode; Semi-bridge inversion formula electric ballast is housed in the bottom end cover, and its output and said one end fluorescent lamp are electrically connected.
The utility model advantage is the one end fluorescent lamp pipe that the light source body is selected the tubule footpath for use, and compact conformation, luminous efficiency height, semi-bridge inversion formula electric ballast replace resistor and form with the structure that capacitor is contacted mutually, and not only power attenuation is little, and working life prolongs.
Description of drawings:
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is an one end fluorescent lamp pipe schematic diagram of the present utility model;
Fig. 3 is the utility model electric ballast electrical schematic diagram.
With reference to this Figure of description, the utility model is described in further detail it.
Fig. 1 is an overall structure schematic diagram of the present utility model, and it is by light source body 1, and translucent cover 2, upper end cover 3, bottom end cover 4 and attaching plug 6 constitute.Light source body 1 is installed in the translucent cover 2, and translucent cover 2 is to be made by glass or plastics.The two ends of translucent cover 2 are fixing tight by upper end cover 3 and bottom end cover 4.Attaching plug 6 usefulness leads connect, and draw from the bottom of bottom end cover 4.It is characterized in that described light source body 1 is that one end fluorescent lamp pipe by diameter 6-10mm constitutes.Crooked 180 ° of its middle part 7 form " U " shape, and straight-tube portion is parallel to each other, and is sealed at both ends and respectively put an electrode 8, as shown in Figure 2.Semi-bridge inversion formula electric ballast is housed in the bottom end cover 4, and its output and said one end fluorescent lamp pipe are electrically connected.Fig. 3 is the utility model electric ballast electrical schematic diagram, and semiconductor diode D1, D2, D3, D4 constitute bridge rectifier, inductor L
0With capacitor C
1, C
2Constitute π type filter circuit, pliotron T1, T2 series connection back is in parallel with capacitor C2, and forms half bridge inverter circuit with L1, L2, L3.Diac DB and resistor R 1, capacitor C3 constitutes circuits for triggering, makes ballast produce pulse current once energising, causes the concussion work of half bridge inverter circuit.Its output and one end fluorescent lamp pipe 1 are electrically connected, and ballast inductance device L4 is connected in the loop of one end fluorescent lamp pipe 1, and its electrical quantity must be complementary with the fluorescent tube 1 of being connected, the standing 4-18W that is changed to of the power of fluorescent tube 1.The diameter of fluorescent tube optimal design is 9-9.5mm in the present embodiment, and inwall scribbles triphosphor Fluorescent Powder, and said electrode 8 is formed by tungsten and rhenium 7: 3 mixed sinterings of ratio by weight.The feature of kind electrode is anti-electron bombard, relative big (10-20) % of electron emission amount under certain electric-field intensity, and firmly shatter-proof.According to the lantern of above-mentioned design, its luminous efficiency average life then can prolong 2-3 doubly about will doubling than utility light commonly used at present both at home and abroad.
According to design of the present utility model, the middle part 7 of the fluorescent tube that described light source body 1 is constituted also can be " ∏ " type or " H " type.Though technology is different, its effect is similar.Be provided with hook 5 on the top of said upper end cover 3, it can be that metal material is made, also can be directly by the plastic pressure injection moulding.When lantern was used for machine repairing illumination, tour in the field, garden, road lighting, hook 5 can use more convenient on the fixing nigh support of this lamp.
Embodiment sample test result of the present utility model is as follows:
Use the supply voltage scope: 220V (50H
Z) ± 10%
Rated power: 12W
Operating current :≤99.2mA
Power factor: 0.55
Luminous flux: 〉=7201m
Luminous efficiency: 〉=601m/w
Average switch life number of times: 〉=12000 times
