Abstract

An ultraviolet lamp comprises a plurality of ultraviolet LED (light emitting diode) lamps, a lamp tube, a circuit board and conductive wires. The plurality of ultraviolet LED lamps are fixedly welded on the circuit board, the circuit board is arranged inside the lamp tube, and the conductive wires penetrate the lamp tube and are electrically connected with the circuit board. Compared with traditional mercury vapor ultraviolet lamps, the ultraviolet lamp is simple in structure and easy to manufacture, omits steam vapor which can pollute the environment and accordingly avoids air damage due to breakage or damage of the lamp tube.

Description

Ultraviolet lamp

Technical field

The utility model relates to a kind of light fixture, particularly relates to a kind of ultraviolet lamp.

Background technology

Ultraviolet ray be a kind of wavelength between visible ray and X ray, the electromagnetic wave of wavelength between 100～400nm.Ultraviolet ray is usually used in sterilization, sterilizing, light decomposition degraded, photocatalysis and other photochemical reactions, is applicable to the sterilizations such as biological study, health, medical treatment, pharmaceuticals industry and food industry.

Traditional ultraviolet sterilizing lamp, it is similar that it lights the fluorescent lamp that principle and general lighting use, its principle of luminosity is to be filled with mercuryvapour in vacuum treated quartz glass tube, lamp tube ends is equipped with filament, by ballast, to filament two ends voltage in addition, excite mercury gas arc discharge and produce ultraviolet ray.Traditional UV sterilamp lamps structure is complicated, more easily causes mercury pollution after discarded, and people healthy had to larger harm.

Utility model content

Based on this, be necessary to provide a kind of simple in structure and environmental protection ultraviolet lamp.

A kind of ultraviolet lamp, comprise a plurality of ultraviolet LED lamps, fluorescent tube, wiring board, conductive lead wire, described a plurality of ultraviolet LED lamp is weldingly fixed on described wiring board, and described wiring board is positioned at described fluorescent tube, and described conductive lead wire is electrically connected to described wiring board through described fluorescent tube.

In one of them embodiment, described wiring board comprises circuit layer, insulating barrier and the metallic plate connecting successively, and described a plurality of ultraviolet LED lamps are welded on described circuit layer, and described conductive lead wire is electrically connected to described circuit layer.

In one of them embodiment, described metallic plate is aluminium metal sheet.

In one of them embodiment, described fluorescent tube is clear tubular, and the cross section of described fluorescent tube is circular.

In one of them embodiment, described fluorescent tube is clear tubular, and the cross section of described fluorescent tube is semicircle.

In one of them embodiment, the flat outer surface on described fluorescent tube is provided with a plurality of hanging rings.

In one of them embodiment, the cross section of described wiring board is the trapezoidal shape without going to the bottom, and has three surfaces of splicing successively, and described a plurality of ultraviolet LED lamps are distributed on described three surfaces of splicing successively.

In one of them embodiment, the intermediate surface in described three surfaces of splicing is successively parallel with the burnishing surface of described fluorescent tube.

Relatively traditional mercuryvapour ultraviolet lamp, above-mentioned ultraviolet lamp is simple in structure, easily manufactured, and without adopting mercuryvapour environment to pollution, fluorescent tube is broken or damage after can not cause air pollution.

The design of semicircle fluorescent tube, because have a burnishing surface, makes ultraviolet lamp be more conducive to be arranged on the smooth objects such as metope.

The cross section of described wiring board is designed to, without the trapezoidal shape of going to the bottom, make a plurality of ultraviolet LED respectively towards different directions, makes the scope in direct irradiation region larger.

The specific embodiment

As shown in Figure 1, it is the structural representation of the ultraviolet lamp 10 of the utility model one preferred embodiment, comprising: a plurality of ultraviolet LED lamps 11, round lamp tube 12, wiring board 13 and conductive lead wire 14.

Described a plurality of ultraviolet LED lamp 11 is weldingly fixed on described wiring board 13.Described wiring board 13 is positioned at described round lamp tube 12, and described conductive lead wire 14 is electrically connected to described wiring board 13 through described round lamp tube 12.

Described wiring board 13 comprises: the circuit layer 131 being fitted and connected successively, insulating barrier 132 and metallic plate 133, described a plurality of ultraviolet LED lamp 11 is uniformly distributed and is weldingly fixed on described circuit layer 131, described conductive lead wire 14 has a plurality of, lay respectively at the two ends of described fluorescent tube 12, for connecting outside electric supply installation, be ultraviolet LED lamp 11 power supplies.

Described a plurality of ultraviolet LED lamp 11 is SMD or direct insertion.The material of described round lamp tube 12 is the transparency materials such as glass material, resin or plastics.The material of metallic plate 133 is the good metallic aluminium of heat conductivility, and the material of insulating barrier 132 is resin, and the material of circuit layer 131 is the good copper of electric conductivity.

Relatively traditional mercuryvapour ultraviolet lamp, above-mentioned ultraviolet lamp 10 is simple in structure, easily manufactured, and without adopting mercuryvapour environment to pollution, fluorescent tube is broken or damage after can not cause air pollution.

As shown in Figure 2, it is the structural representation of the ultraviolet lamp 20 of another preferred embodiment of the utility model, different from the ultraviolet lamp 10 shown in Fig. 1: fluorescent tube 22 is semicircle fluorescent tube.Described fluorescent tube 22 comprises: interconnective semicircle cambered surface 222 and burnishing surface 221.The recline inner side of described burnishing surface 221 of metallic plate 133, circuit layer 131 is towards described semicircle face 222.

The design of semicircle fluorescent tube 22, because have a burnishing surface 221, makes ultraviolet lamp 20 be more conducive to be arranged on the smooth objects such as metope.

As shown in Figure 3, it is the outer surface structure schematic diagram of burnishing surface 221 of the fluorescent tube 22 of the ultraviolet lamp 20 shown in Fig. 2, the outer surface of the burnishing surface 221 of the fluorescent tube 22 of ultraviolet lamp 20 is provided with the link 51 for hanging, for facilitating hanging of ultraviolet lamp 20.In other embodiment, link 51 can change hook, hanging hole etc. into for hard-wired mechanism.

As shown in Figure 4, it is the structural representation of the ultraviolet lamp 30 of another preferred embodiment of the utility model, with the difference of Fig. 2 middle-ultraviolet lamp light fixture 20 is: wiring board 33 for cross section for without the trapezoidal shape of going to the bottom, there are three surperficial wiring boards of splicing successively.A plurality of ultraviolet LED lamps 31 are distributed on described three surfaces of splicing successively.

So, described a plurality of ultraviolet LED, respectively towards different directions, make the scope in direct irradiation region larger.

The above embodiment has only expressed several embodiment of the present utility model, and it describes comparatively concrete and detailed, but can not therefore be interpreted as the restriction to the utility model the scope of the claims.It should be pointed out that for the person of ordinary skill of the art, without departing from the concept of the premise utility, can also make some distortion and improvement, these all belong to protection domain of the present utility model.Therefore, the protection domain of the utility model patent should be as the criterion with claims.
