Abstract
The utility model relates to an energy-saving lamp with a cover. The lamp comprises a lamp cap below which a lamp holder is arranged, wherein the lamp holder is internally connected with a ballast assembly, a base plate and a lamp tube; the lamp holder is externally connected with a lamp cover; the ballast assembly is connected on the base plate; the lamp tube and the lamp cover constitute the lamp body; and the lamp tube is provided with a cold end protruding out of the lamp tube. The lamp is characterized in that the lamp cover is provided with a heat dissipation hole and the cold end extends to the external environment outside the lamp cover after passing through the heat dissipation hole. The utility model provides the energy-saving lamp with the cover, which can achieve the stable highest light out and greatly shorten the rise time.
Description
Technical field
The utility model relates to a kind of band cover electricity-saving lamp with lampshade.
Background technology
The electricity-saving lamp cold junction is a little space and protrudes in lamp body, and this space does not have electric current to pass through when lamp works, and temperature is lower, so be referred to as cold junction; In order to obtain the output of the highest normal light, the mercury vapor pressure that must keep in the fluorescent tube is stabilized in certain stress level, and the cold spot (being cold junction) of mercury vapor pressure and the interior operating temperature of fluorescent tube is corresponding in the fluorescent tube; The selection dependence experience mostly of cold junction is determined at present.
Electricity-saving lamp for the band lampshade, temperature inside is all very high about more than 50 degrees centigrade, cold junction is influenced greatly by the interior thermal environment of environment lampshade, be difficult for cooling, cause energy-conservation light output unstable, use amalgam (promptly in cold junction, adorning Amalgam core column) though fluorescent tube can obtain stable light output, the rise time is longer, the rise time refers to start to the time that reaches normal light output from lamp.
For finding suitable position, make the temperature of cold junction lower, or the cold junction temperature of band amalgam is lower, someone has designed a kind of is that " the cold junction device of low-pressure mercury vapor type discharge lamp " (application number is: 99211264.8), its external glass tube inserts on the tube wall of fluorescent tube and communicates and be hedged off from the outer world with fluorescent tube inside.Though it has found cold spot, improve normal light output, its rise time is still very long.
The utility model content
The utility model mainly is that the electricity-saving lamp that solves existing in prior technology band lampshade reaches the technical problem that light is exported instability, rise time length etc., a kind of band cover electricity-saving lamp is provided, make electricity-saving lamp can reach the highest stable light output, and shorten the rise time greatly.
Above-mentioned technical problem of the present utility model is mainly solved by following technical proposals: it comprises lamp holder, lamp holder has lamp socket, be connected with ballast component, substrate and fluorescent tube in the described lamp socket, described lamp socket is connected with lampshade outward, and described ballast component is connected on the substrate, and described fluorescent tube and lampshade constitute lamp body, described fluorescent tube is provided with the cold junction of outstanding fluorescent tube, it is characterized in that: described lampshade is provided with louvre, and described cold junction stretches out in the external environment outside lampshade by louvre.Cold junction can by with the heat exchange of external environment Cryogenic air, cooling promptly, it is defeated more than 70% to make that light output reaches normal light, rise time is all less than 40 seconds, not only reach, and being far superior to the accurate relevant regulations of asterisk of the EUP of European Union instruction and american energy, the EUP of European Union instruction regulation reaches 60% normal light output time (rise time) from lighting a lamp: naked lamp was less than 60 seconds, and band covered lamp less than 120 seconds; The asterisk of american energy is accurate to be stipulated from the 90% normal light output time of lighting a lamp: naked lamp was less than 60 seconds, and band cover lamp was less than 180 seconds.
Louvre and cold junction are suitable, and as preferably, described louvre aperture is more than or equal to the cold junction external diameter.
As preferably, be provided with stem stem in the described cold junction, be provided with amalgam in the described stem stem.
In order to dispel the heat better,, be provided with thermal paste in the described louvre as preferably.Coat thermal paste at the louvre inwall, the effect that can obtain.
As preferably, described fluorescent tube is connected the fluorescent-tube fixer bottom, is provided with fixture in the described lamp body, and described substrate is installed in fixture top, and described fluorescent tube links to each other with fixture.
As preferably, described cold junction is arranged on the fluorescent tube bottom.
The utility model can be useful on the electricity-saving lamp of various types of band lampshades on the market, and as preferably, described fluorescent tube is U type pipe or helix tube.
The beneficial effect that the utility model brings is, alleviate of the influence of the interior high temperature of lampshade to cold junction, by contacting with external environment, make cold junction promptly to lower the temperature, the utility model makes the electricity-saving lamp of band lampshade reach the highest light output and the shortest rise time, make the cold junction position determine become easy.
Description of drawings
Accompanying drawing 1 is a kind of decomposition texture schematic diagram of the present utility model;
Accompanying drawing 2 is a kind of structural representations of lampshade in the accompanying drawing 1.
The specific embodiment
Below by embodiment, and in conjunction with the accompanying drawings, the technical scheme of utility model is described in further detail.
Embodiment: band cover electricity-saving lamp of the present utility model is by Fig. 1, shown in 2, comprise lamp holder 1, lamp holder is connected with lamp socket 21 time, be connected with the ballast component in the lamp socket 2, substrate 3, spiral cast fluorescent tube 6 and fluorescent-tube fixer 5, fluorescent tube 6 is connected fluorescent-tube fixer 5 bottoms, substrate 3 is equipped with on fluorescent-tube fixer 5 tops, be fixed with the ballast component on the substrate 3, the lamp socket 2 outer lampshades 8 that are equipped with, fluorescent tube 6 is surrounded, be shaped on the cold junction 7 that protrudes fluorescent tube 6 on the fluorescent tube 6, cold junction 7 is in fluorescent tube 6 bottoms, be shaped on stem stem in the cold junction 7, amalgam is housed in the stem stem, is shaped on heat abstractor 4 on the lampshade 8, heat abstractor 4 has a louvre on the lampshade 8, the louvre aperture equates with cold junction 7 external diameters, the louvre inwall scribbles thermal paste, and cold junction 7 stretches out in the external environment outside lampshade 8 by louvre, for saving material, lamp socket 2 and fluorescent-tube fixer 5 are plastic products.
