Abstract

The utility model provides a high-efficiency energy-saving lamp, which comprises a lampshade, a lamp tube and ballasts. The lamp tube is arranged in the lampshade, and the ballasts are arranged at the two ends of the lampshade; an electrode which is electrically connected with the ballasts is arranged in the lampshade, the lamp tube is a fluorescent lamp, and a fluorescent powder layer is coated on the outer wall of the lamp tube. The high-efficiency energy-saving lamp has the characteristics that: the fluorescent powder layer is arranged on the outer wall of the lamp tube, so that visible light emitted by fluorescent powder lights outside the lamp tube and does not need to penetrate through the tube wall of the lamp tube, thereby reducing losses of light rays; therefore, the energy-saving lamp with the same power 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.

Further, described lampshade is cylindrical, is provided with receiving space in it, and fluorescent tube is positioned at receiving space inside.

Be evacuated in the described lampshade, and further be filled with argon gas and mercury vapour, this lampshade adopts clear glass or plastics to make.

Described ballast electrically connects by pin and the power supply that its end is provided with.

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 the specific embodiment of the present utility model is described in detail.

In the accompanying drawing,

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

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

Fig. 3 is the cutaway view of the utility model second embodiment energy-efficient lamp;

Fig. 4 is the cutaway view of the utility model the 3rd embodiment energy-efficient lamp.

The specific 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, the energy-efficient lamp of the utility model first embodiment 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, and its cutaway view is two concentric circles; Topmost improvements of the present utility model are that phosphor powder layer 21 evenly is coated with the outer wall of being located at fluorescent tube 2.

Consult Fig. 3, profile for the energy-efficient lamp of the utility model second embodiment, the electricity-saving lamp of present embodiment is formed identical with first embodiment, difference is, described fluorescent tube 3 is provided with respect to the center line of lampshade 4 is eccentric, thereby can reflecting layer or reflecting plate (not shown) be set in a side of lampshade 4 close fluorescent tubes, thereby reach better illuminating effect.

Consult Fig. 4, be the profile of the energy-efficient lamp of the utility model the 3rd embodiment, in the present embodiment, the part is coated with phosphor powder layer 21 on the outer wall of fluorescent tube 2, and for example on half outer surface, and remainder is not coated with fluorescent material.Thereby can save fluorescent material.

Operation principle: energy-efficient lamp of the present utility model adopts cold cathode to light, specifically, when the pin 52 of ballast 5 is connected the heated by electrodes of power supply to lampshade 4, electrode emission electronics (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.Moreover, owing to can be coated with the position of phosphor powder layer, reach adjusting to light-illuminating angle and brightness with this by artificial control, design hommization more.

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 domain of the utility model accompanying Claim.
