The LED lamp welded on the glass has the advantages of being attractive and good in heat dissipation performance and enabling the service life of the LED lamp to be effectively extended due to the fact that the LED lamp is welded on the glass substrate.

Description

A kind ofly be welded on LED lamp on glass

Technical field

The utility model relates to the LED lighting technical field, relates in particular to a kind of LED lamp on glass that is welded on.

Background technology

In recent years, LED was used widely in every field as new light sources; But LED can produce heat in luminescence process.Heat not only has a strong impact on the wavelength of LED as can not in time distributing, power, and parameters such as luminous flux also can make the life-span of lamp sharply decay.And the LED light fixture that uses at present substantially all is welded in the LED pipe on the aluminium base, and aluminium base is mutually bonding with aluminium radiator by heat-conducting glue again.Because aluminium base and heat-conducting glue thermal resistance are big, its thermal conductivity only is 0.2 W/mK, so especially bulb lamp power is all less for present LED lamp.

The utility model content

The purpose of this utility model is at the deficiencies in the prior art, and a kind of LED lamp on glass that is welded on is provided.

The purpose of this utility model is achieved through the following technical solutions: a kind ofly be welded on LED lamp on glass, it comprises lamp holder unit, lamp body unit, power subsystem and lampshade; Wherein, the lamp holder unit is spun by lamp holder and metal spiral outer casing screw and forms; Have dead slot in the lamp holder, the lamp holder bottom has holddown groove, circular groove and two through wires holes that communicate with dead slot; Power subsystem places in the dead slot, and an end is electrically connected with the metal spiral shell, and the LED terminals on the other end passes through wires hole and is fixed on holddown groove are electrically connected; The seam of lampshade end inserts in the circular groove of lamp holder bottom; Described lamp body unit comprises glass substrate, silver foil circuit, LED lamp and brace, and glass substrate is fixed on the holddown groove, sintering silver foil circuit on the glass substrate, and the LED lamp is welded on the silver foil circuit, and the silver foil circuit is electrically connected with the LED terminals by brace.

The beneficial effects of the utility model are: the utility model is welded on the LED lamp on the glass substrate, and is not only attractive in appearance, and perfect heat-dissipating, can effectively prolong the service life of LED lamp.

Among the figure, glass substrate 1, silver foil circuit 2, scolding tin 3, LED lamp 4, high-temperature oxidation resistant glue 5, lamp body 6, lamp holder 7, metal spiral shell 8, through wires hole 9, power subsystem 10, brace 11, circular groove 12, dead slot 13, lampshade 14, seam 15, holddown groove 16, LED terminals 17, AC power 18, capacity voltage dropping circuit 19, rectification circuit 20, filtering constant-current circuit 21, LED lamp group 22.

The specific embodiment

Shown in Fig. 1-4, the utility model is a kind of LED lamp on glass that is welded on, and it comprises lamp holder unit, lamp body unit, power subsystem 10 and lampshade 14; The lamp holder unit is spun by lamp holder 7 and metal spiral shell 8 screw threads and forms; Have dead slot 13 in the lamp holder 7, lamp holder 7 bottoms have holddown groove 16, circular groove 12 and two through wires holes 9 that communicate with dead slot 13, and the material of lamp holder 7 can be plastics, pottery or glass.Power subsystem 10 places in the dead slot 13, and an end is electrically connected with metal spiral shell 8, and the other end passes through wires hole 9 and is electrically connected with LED terminals 17 on the holddown groove 16.The seam 15 of lampshade 14 ends inserts in the circular groove 12 of lamp holder 7 bottoms.Lamp body unit comprises glass substrate 1, silver foil circuit 2, LED lamp 4 and brace 11, glass substrate 1 is fixed on the holddown groove 16, sintering silver foil circuit 2 on the glass substrate 1, LED lamp 4 is welded on the silver foil circuit 2 by scolding tin 3, scribble high-temperature oxidation resistant glue 5 on the silver foil circuit 2, silver foil circuit 2 is electrically connected with LED terminals 17 by brace 11.

Power supply 10 comprises the capacity voltage dropping circuit 19, rectification circuit 20 and the filtering constant-current circuit 21 that is composed in series by capacitor C 2 and resistance D5 of being made up of four diode D1-D4 that are composed in parallel by capacitor C 1 and resistance R 1; Capacity voltage dropping circuit 19, rectification circuit 20 and filtering constant-current circuit 21 link to each other successively.The other end of capacity voltage dropping circuit 19 links to each other with AC power 18, and filtering constant-current circuit 21 other ends link to each other with LED lamp 4 on being welded on silver foil circuit 2 by lead.
