Abstract

LED screw bulb for down lamps in an incandescent bulb shape comprises a screw lamp holder, a lamp and a lamp shade, wherein a power source board, an LED chip array, a substrate for the LED chip array, and a reflective heat-conducting bowl matched with the lamp tightly are arranged in the LED screw bulb. Energy efficiency of the LED screw bulb compared with an incandescent lamp is improved evidently, and the LED screw bulb can be changed directly without hand scalding, and is comfortable to touch and long in service life.

Description

The LED screw-socket bulb

Technical field

The utility model belongs to lighting device parts group, i.e. F21V in International Patent Classification (IPC); Also relevant with the semiconductor devices group, i.e. H01L.Be particularly related to the screw energy-saving lamp bubble that cartridge lamp is used.

Technical background

In bar desk or house fitting-up, adopt cartridge lamp usually, comprise lamp and the tubule following lamp of hanging cylindrical cover of seat in furred ceiling.Its bulb none without the screw socket incandescent lamp bulb.Along with people's energy-saving and emission-reduction subtract the raising that carbon is realized, the research and development of replacing incandescent lamp with LED also launch thereupon, so that improve efficiency, accelerate to dispel the heat life-saving.

The utility model content

The purpose of this utility model provides the LED screw-socket bulb that a kind of cartridge lamp is used, and it is than prior art efficiency height, rapid heat dissipation.

It is as follows to disclose new technical scheme:

The LED screw-socket bulb that a kind of cartridge lamp is used has screw socket at least.Its lower end be fixed with lamp body and with the lampshade of lamp body clamping, also have power panel and led chip array in the lamp body, screw socket, lamp body and lampshade totally become airtight incandescent lamp blister, it is characterized in that:

Power panel inserts in the groove of top in the lamp body, and its input line links to each other with the screw socket afterbody, and its output line links to each other with the led chip array;

The substrate that the led chip array is housed is close on the reflective heat conduction bowl, and it is discoid that said reflective heat conduction bowl is inversion, with the inboard tight fit in lamp body lower end.

The LED screw-socket bulb of making according to such scheme, owing to adopt led chip array and reflective heat conduction bowl, therefore improved efficiency by a relatively large margin, rapid heat dissipation, prolonged the life-span, can directly replace incandescent lamp bulb and non-scald on hand, good hand touch, insulation, safer when replacing is installed, wherein 5 watts bulb is equivalent to 40 watts incandescent lamp.

Wherein: 1, screw socket 2, lamp body 3, power panel 4, screw 5, reflective heat conduction bowl 6, substrate 7, led chip array 8, lampshade

The specific embodiment:

The LED screw-socket bulb that a kind of cartridge lamp is used, has screw socket 1 at least, its lower end be fixed with lamp body 2 and with the lampshade 8 of lamp body 2 clampings, also have power panel 3 and led chip array 7 in the lamp body 2, screw socket 1, lamp body 2 and lampshade 8 totally become airtight incandescent lamp blister:

Power panel 3 inserts in the groove of top in the lamp body 2, and its input line links to each other with the afterbody of screw socket 1, and its output line links to each other with led chip array 7;

The substrate 6 that led chip array 7 is housed is close on the reflective heat conduction bowl 5, and it is discoid that said reflective heat conduction bowl 5 is inversion, with the inboard tight fit in lamp body 2 lower ends.

The lamp body 2 that lampshade 8 and the macromolecular material that macromolecular material is made made utilizes dop to be connected with draw-in groove, is adhesively fixed.

Substrate 6, reflective heat conduction bowl 5 are fixed on the lamp body 2 by screw 4.
