A LED power driving is designed into an inner cavity of the lamp base, a driving part is invisible, harmony of the whole increases surfaces which are luminous, the lamp base can be used for heat dissipation at the same time, heat dissipation effects are increased, two luminous cavities are arranged, the two luminous cavities can be controlled separately, luminous angles of each cavity are different, and design of secondary reflection lighting eliminates influences of glare.

Description

A kind of LED bulb lamp

Technical field

The present invention relates to a kind of energy-saving lighting lamp, particularly a kind of LED bulb lamp.

Background technology

Present existing LED bulb lamp is main mainly with hemispherical greatly, these LED bulb lamps are mainly used to replace traditional electricity-saving lamp, generally be applicable to Down lamp and desk lamp and some floor lamps, existing LED bulb lamp is in the majority with direct light type, add that the ground glass cover just can weaken its dazzle, and seen in single at lighting angle, in addition aspect whole light fixture ratio, power drives and the radiator structure main space that accounted for, and light-emitting area only has sub-fraction, therefore seems that LED bulb lamp integral body has discoordination.

Summary of the invention

The objective of the invention is provides a kind of LED bulb lamp in order to overcome the problems referred to above.

for achieving the above object, the method that the present invention adopts is: a kind of LED bulb lamp, comprise lamp holder, lighting cavity, LED light source structure and power drives mounting structure, described lighting cavity comprises the upper cavity of two parts up and down and the lower chamber that can control separately, be provided with the LED light source structure between upper cavity and lower chamber, radiator structure by an aluminum between described upper cavity and lower chamber separates, described upper cavity for penetrating the type lighting cavity once, described lower chamber is a lateral type lighting cavity, be provided with cloche on described upper cavity.

As a modification of the present invention, be equipped with reflector in described upper cavity and lower chamber.

As a modification of the present invention, the described reflector I that is arranged at upper cavity is the structure of a taper.

As a modification of the present invention, the described reflector II that is arranged in lower chamber is curved surface column.

As a modification of the present invention, described power drives mounting structure is arranged in described lamp holder.

As a modification of the present invention, described power drives mounting structure is a T-shaped structure.

As a modification of the present invention, be provided with annular aluminum design between described upper cavity and cloche, the LED light source structure in described upper cavity is arranged at the inner ring of described annular aluminum design.

As a modification of the present invention, the LED light source structure in described lower chamber is arranged on the inner ring of described radiator structure.

The invention has the beneficial effects as follows:

The present invention is by designing the LED power drives in the lamp holder inner chamber, stealthy drive part, make whole harmony, increase luminous face, also can dispel the heat by lamp holder simultaneously, increased radiating effect, by two lighting cavity are set, and two lighting cavity can be controlled separately, and the lighting angle of each cavity is different simultaneously, adopt secondary reflection bright dipping design to eliminate the impact of dazzle.

Wherein each parts are: 1 upper cavity, 2 radiator structures, 3 lower chambers, 4 lamp holders, 5 cloches, 6 reflector I, 7 reflector II, 8 power drives mounting structures, 9LED light-source structure.

The specific embodiment

A kind of LED bulb lamp as shown in Figure 1, compriselamp holder 4, lighting cavity, LEDlight source structure 9 and powerdrives mounting structure 8, two parts up and down that describedlighting cavity 1 can be controlled separately,upper cavity 1 andlower chamber 3, theradiator structure 2 by an aluminum betweenupper cavity 1 andlower chamber 3 separates.Be provided with the LED light source structure between upper cavity and lower chamber.

Be provided with between describedupper cavity 1 andcloche 5 be used to being connected the annular aluminum design ofupper cavity 1 withcloche 5, LEDlight source structure 9 inupper cavity 1 is arranged at the inner ring of described annular aluminum design, can dispel the heat to the LEDlight source structure 9 inupper cavity 1 by annular aluminum design.Described lower chamber LED light source structure is arranged on inboard one circle of theradiator structure 2 of described aluminum, and the 2 pairs of bulb lamps of radiator structure by aluminum dispel the heat.

Describedupper cavity 1 for penetrating the type lighting cavity once, its lighting angle is side-lower,lower chamber 3 is a lateral type lighting cavity, its lighting angle is the side, by different lighting angles is set, select for many again parts when using light fixture, be provided withcloche 5 on describedupper cavity 1.

Further, be equipped with reflector in describedupper cavity 1 andlower chamber 3, the reflector I 6 that is arranged atupper cavity 1 is the structure of a taper, produce the side-lower lighting angle by reflector I 6, the described reflector II 7 that is arranged inlower chamber 3 is curved surface column, reflector II 7 by curved surface column produces the lateral direction light emission angle, andupper cavity 1 andlower chamber 2 all adopt the secondary reflection design, avoid direct glare.

A nearlyer step ground, described powerdrives mounting structure 8 is arranged in described lamp holder, and described power drives is installed knot, and 8 is a T-shaped structure.This design is not only stealthy LED drive part has increased the light-emitting area of light fixture, and power drives also can be dispelled the heat bylamp holder 4 simultaneously.

The present invention is by designing the LED power drives in the lamp holder inner chamber, stealthy drive part, make whole harmony, increase luminous face, also can dispel the heat by lamp holder simultaneously, increased radiating effect, by two lighting cavity are set, and two lighting cavity can be controlled separately, and the lighting angle of each cavity is different simultaneously, adopt secondary reflection bright dipping design to eliminate the impact of dazzle.

The above is only preferred embodiment of the present invention, is not to be the present invention to be done the restriction of any other form, and according to any modification or equivalent variations that technical spirit of the present invention is done, still belongs to the present invention's scope required for protection.
