Description

The LED bulb

Technical field

The utility model relates to a kind of LED bulb.

Background technology

Traditional bulb is an incandescent light bulb, and its illumination is lower, and light is not bright, not energy-conservation.Occurred the fluorescent lamp bulb behind incandescent lamp bulb, though it is energy-conservation, light is brighter, since a large amount of fluorescent material that uses, therefore not enough environmental protection.Need to vacuumize after the glass shell body and function of traditional incandescent light bulb fire sealing by fusing is molten, and the cell-shell gas leakage of in a single day breaking, bulb can not use with regard to scrapping.Occurred more energy-conservation at present and led light source environmental protection, produced the LED bulb thereupon, existing LED bulb common configuration complexity, mainly comprise three parts---lamp holder, neck, luminous sphere, lamp holder all is a standard component, neck generally has plastics and two kinds of materials of metal, neck generally is lighttight, be mainly used in and connect and heat radiation or placement driver, luminous sphere generally has two kinds of materials of plastic and glass, is used for printing opacity, and generally needs additionally to set up heat abstractor, it is higher that appearance touches up temperature, so its outward appearance has been compared than big difference with the ordinary incandescent lamp bulb with internal structure.And the manufacture method of the manufacture method of existing LED bulb and traditional incandescent light bulb has than big difference, can not make full use of existing incandescent light bulb production line and produce the LED bulb.

The utility model content

Technical problem to be solved in the utility model is to overcome the deficiencies in the prior art, provide that a kind of simple in structure, energy-saving and environmental protection, long service life, temperature are low, outward appearance and internal structure and the identical LED bulb of ordinary incandescent lamp bulb, the housing of described LED bulb break also can continue luminous.

The technical scheme that the utility model adopted is: the utility model comprises lamp holder, the glass bulb housing, the afterbody of described glass bulb housing and described lamp holder are fixedly connected, described LED bulb also comprises the drive circuit assembly, light source bracket, led light source, described led light source is fixed on the described light source bracket, the afterbody sealing by fusing of described glass bulb housing is fixed on the afterbody of described light source bracket and described led light source and described light source bracket is enclosed in inner chamber, described drive circuit assembly be positioned at described lamp holder and by lead respectively with described lamp holder, described led light source is electrically connected.

Described led light source comprises radiating bottom plate and is positioned at several LED that are arranged in array on the described radiating bottom plate.

Described LED layered arrangement.

Described lamp holder is screw socket or buckle lamp holder.

Complete printing opacity of described glass bulb housing or part printing opacity.

The beneficial effects of the utility model are: because LED bulb described in the utility model also comprises the drive circuit assembly, light source bracket, led light source, described led light source is fixed on the described light source bracket, the afterbody sealing by fusing of described glass bulb housing is fixed on the afterbody of described light source bracket and described led light source and described light source bracket is enclosed in inner chamber, described drive circuit assembly be positioned at described lamp holder and by lead respectively with described lamp holder, described led light source is electrically connected, the utility model adopts described led light source to replace the tungsten filament of conventional incandescent bulb and with the housing combination of led light source and conventional incandescent, identical with existing ordinary incandescent lamp bulb profile from the appearance, have only lamp holder and luminous sphere two parts, luminous sphere is a glass, can think that also neck and luminous sphere are one, and neck is a printing opacity, give strong visual impact, better than existing LED bulb; Because the two principle of luminosity difference, therefore led light source of the present utility model does not need the environment of vacuum just can be luminous, therefore simple in structure, also not influence described led light source luminous even the housing of described LED bulb breaks, and is unlikely to make bulb to be scrapped, and LED itself has the advantage of energy-conserving and environment-protective, and caloric value is little, therefore just can dispel the heat by the air in the described glass bulb housing, LED bulb temperature of the present utility model is lower, can not resemble traditional incandescent light bulb hot; LED bulb of the present utility model can substitute traditional incandescent light bulb fully, play energy-saving effect, the light efficiency height of LED, power is the brightness that the LED bulb of 6W just can reach the conventional incandescent bulb of 60W, and the LED life-span is long, the life-span of LED bulb of the present utility model can reach more than 20000 hours, and the conventional incandescent bulb has only 10000 hours; So LED bulb structure of the present utility model is simple, energy-saving and environmental protection, long service life, temperature are low, outward appearance and ordinary incandescent lamp bulb are identical, the housing of described LED bulb break also can continue luminous;

Because the utility model LED bulb all is to adopt the fiery sealing by fusing of glass shell body and function with the manufacture method of traditional incandescent light bulb, but the manufacture method of the utility model LED bulb does not need the step that vacuumizes, therefore production technology is simpler, production cost is also lower than ordinary incandescent lamp bulb, therefore from cost, more cheap than existing LED bulb, explained hereafter LED bulb by fiery sealing by fusing is an invention of this area, and require also lower to the tightness of sealing by fusing, so the manufacture method of the utility model LED bulb can make full use of existing incandescent light bulb production line and produce, and technology is simpler, production efficiency is higher.
