Abstract
The utility model relates to a lamp, in particular to an energy-saving lamp, which comprises a lamp adaptor, wherein a lamp base is arranged below the lamp adaptor, a ballast component, a base plate and a lamp tube are connected in the lamp base, a lampshade is connected to the outer side of the lamp base, the ballast component is connected to the base plate, the lamp tube and the lampshade form a lamp body, and the lamp tube is provided with a cold junction protruding from the lamp tube. The energy-saving lamp is characterized in that a radiating hole is arranged on the lamp base, and the cold junction passes through the radiating hole to extend into the external environment outside the lampshade. The energy-saving lamp can achieve the highest stable light output while shortening rise time greatly.
Description
Technical field
The utility model relates to a kind of light fixture, relates in particular to a kind of electricity-saving lamp.
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 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 lamp socket 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, be provided with fixture in the described lamp body, described substrate is installed in fixture top, described fluorescent tube links to each other with fixture, be connected with the stem stem sheath on the described fixture, described cold junction is arranged on the fluorescent tube upper end, and described cold junction passes the stem stem sheath.
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.
