Abstract

The utility model discloses a highly efficient energy-saving lamp, which comprises a lamp cover, a lamp arranged in the lamp cover and two ballasts arranged at both ends of the lamp cover, wherein, the lamp cover is provided with electrodes electrically connected with the ballasts; the lamp is a fluorescent lamp and the outer wall is coated with a phosphor layer. Because of the phosphor layer arranged at the outer wall of the lamp, visible light from the phosphor can emit light outside the lamp without penetrating the wall of the lamp. The utility model reduces the consumption of the light beam and has better brightness.

Description

Energy-efficient lamp

Technical field

The utility model relates to a kind of illuminating lamp, particularly a kind of energy-efficient lamp.

Background technology

The ballast that electricity-saving lamp commonly used comprises lampshade, is located at the fluorescent tube in the lampshade and is located at lamp tube ends respectively and electrically connects with fluorescent tube, pin and power supply (not shown) electric connection that ballast is provided with by its end are so that fluorescent tube is shinny.It is low with price, use reliable and be extensive use of as people, yet because the fluorescence coating of fluorescent tube is arranged at the inwall of fluorescent tube, its light that sends need pass the tube wall of fluorescent tube, and the brightness meeting of light is subjected to loss.

Summary of the invention

The purpose of this utility model provides a kind of energy-efficient lamp, and its fluorescence coating is arranged at the outer wall of fluorescent tube, can strengthen the brightness of electricity-saving lamp under the constant prerequisite of the power that keeps lamp.

For achieving the above object, the utility model provides a kind of energy-efficient lamp, comprising: lampshade, be located at the fluorescent tube in the lampshade and be located at the ballast at lampshade two ends; Be provided with the electrode that electrically connects with ballast in the lampshade, fluorescent tube is a fluorescent lamp, is coated with phosphor powder layer on its outer wall.

The beneficial effects of the utility model: phosphor powder layer is arranged at the outer wall of fluorescent tube, makes that the visible light that sends by fluorescent material is luminous outside fluorescent tube, and need not to pass the tube wall of fluorescent tube, has reduced the loss of light, makes the electricity-saving lamp of same power have better brightness.

In order further to understand feature of the present utility model and technology contents, see also following about detailed description of the present utility model and accompanying drawing, yet appended graphic only provide with reference to and the explanation usefulness, be not to be used for the utility model is limited.

Description of drawings

Below in conjunction with accompanying drawing,, will make the technical solution of the utility model and other beneficial effects apparent by embodiment of the present utility model is described in detail.

In the accompanying drawing,

Fig. 1 is the schematic diagram of energy-efficient lamp of the present utility model;

Fig. 2 is the cutaway view of Fig. 1 along the 2-2 direction.

Embodiment

For further setting forth technological means and the decorative effect thereof that the utility model is taked, be described in detail below in conjunction with preferred embodiment of the present utility model and accompanying drawing thereof.

Consult Fig. 1-2, energy-efficient lamp of the present utility model comprises: lampshade 4, be located at the fluorescent tube 2 in the lampshade 4 and be located at the ballast 5 at lampshade 4 two ends; Ballast 5 electrically connects with power supply (not shown) by the pin 52 that its end is provided with, so that fluorescent tube 2 is shinny, and, but ballast 5 stabling current also; Lampshade 4 adopts clear glass or other transparent material plastics to make, and is cylindrical, is provided with receiving space 42 in it, be evacuated in the receiving space 42, and further be filled with argon gas and mercury vapour, and, the electrode (not shown) that electrically connects with ballast 5 be provided with in the lampshade 4; Fluorescent tube 2 is a fluorescent lamp, is positioned at the middle part of the receiving space 42 of lampshade 4; Topmost improvements of the present utility model are that phosphor powder layer 21 is coated with the outer wall of being located at fluorescent tube 2.

Operation principle: energy-efficient lamp of the present utility model adopts cold cathode to light, specifically, when pin 52 energized of ballast 5 heated by electrodes to lampshade 4, electrode emitting electrons (scribbling the electronics powder on the electrode), a large amount of electronics are flow through from lampshade 4, argon gas and mercury vapour that electronics impacts in the lampshade 4 at the volley send ultraviolet ray (electron collision ar atmo generation inelastic collision, obtain energy after the ar atmo collision and clashed into mercury atom again, mercury atom transition after absorbing energy produces ionization, send the ultraviolet ray of 253.7nm), fluorescent material on ultraviolet ray excited fluorescent tube 2 outer walls sends visible light.Because fluorescent material of the present utility model is coated with the outer wall of being located at fluorescent tube, the feasible visible light that sends by fluorescent material need not to pass the tube wall of fluorescent tube, has reduced the loss of light, makes the electricity-saving lamp of same power have better brightness.

The above; for the person of ordinary skill of the art; can make other various corresponding changes and distortion according to the technical solution of the utility model and technical conceive, and all these changes and distortion all should belong to the protection range of the utility model accompanying Claim.

Claims (5)
