Abstract
The utility model discloses an LED bulb lamp. The LED bulb lamp comprises a lampshade, an LED lamp panel, a radiator, an LED driving circuit board and a lamp cap. The lampshade and the LED lamp panel are fixed on the radiator. The other end of the radiator is connected with the lamp cap. The LED driving circuit board extends from the inside of the lamp cap into the radiator. The lampshade is of a mushroom shape, is hollow inside, and has a radian. According to the LED bulb lamp, the lampshade of the mushroom shape is used so that the front of the LED bulb lamp can be irradiated by the LED bulb lamp and the back of the LED bulb lamp also can be irradiated by the light reflected through the inner wall of the lampshade; compared with an existing LED lighting product, the LED bulb lamp has a great improvement in emission angle and greatly improves luminous efficacy.
Description
Technical field
The utility model relates to the LED lighting field, relates in particular to a kind of LED bulb lamp.
Background technology
At present, normal lighting commonly used, adopt incandescent lamp and LED illumination usually.
Known incandescent lamp adopts tungsten filament when energising to produce high temperature and luminous usually, can realize 360 ° omnibearing luminous, although the lighting angle of incandescent lamp is more satisfactory, its light efficiency is too low, has expended a large amount of energy, does not meet the theory of energy-conserving and environment-protective.
The light source of LED illuminating product is the semiconductor diode luminescence technology, is a kind of light source of straight hair light, although its light efficiency has improved, lighting angle is limited, and generally lower than 180 °, namely there is light in the dead ahead of lamp, but the rear of lamp is shade basically.
The utility model content
In order to overcome the existing limited deficiency of LED illuminating product lighting angle, the LED bulb lamp that provides a kind of lighting angle that relatively has the LED illuminating product now to improve a lot is provided the purpose of this utility model.
To achieve these goals, the utility model solves the technical scheme that the problem of its technology takes and is:
A kind of LED bulb lamp, comprise lampshade, LED lamp plate, radiator, LED drive circuit plate and lamp holder; Described lampshade, LED lamp plate are fixed on radiator, and the other end of radiator is connected with lamp holder, and described LED drive circuit plate extends in radiator in lamp holder; Described lampshade is inner hollow and the mushroom-shaped lampshade with radian.
Described lampshade is the lampshade of transparent PC material.
Described lampshade diameter is than the large 5-15mm of the diameter of radiator; The utility model adopts the mushroom-shaped lampshade, and the diameter of lampshade makes bulb lamp except the dead ahead that shines lamp greater than the diameter of radiator, the reflective rear that can also shine lamp of lampshade inwall.
Described lampshade is connected by Elastic buckle or snap close with radiator.
Described LED lamp plate is screwed in the top of radiator; LED lamp plate of the present utility model position, higher than the basic plane of radiator, can directly irradiate light to the rear of lamp.And the position of common LED light source is lower than the basic plane of radiator, and light can only shine the dead ahead of lamp.
Described radiator is the fine aluminium radiator of cold forging die cast.
Described radiator is provided with 40 fin, thereby has enlarged area of dissipation, has effectively improved radiating efficiency.
Described lamp holder is screw socket, or bayonet socket.
The beneficial effects of the utility model are that the lighting angle of relatively existing LED illuminating product has greater improvement and enhancement, and has greatly improved the optical efficiency of LED bulb lamp.
The accompanying drawing explanation
Fig. 1 is the structural representation of the utility model embodiment.
In figure: 1, lampshade; 2, LED lamp plate; 3, radiator; 4, LED circuit drive plate; 5, lamp holder; 6, screw.
The specific embodiment
Below in conjunction with drawings and Examples, the utility model is described further:
The diameter of the lampshade 1 of bulb lamp of the prior art equates just with the diameter of radiator 3, just in time cover radiator 3 fully, and the position of common LED lamp plate 2 is lower than the basic plane of radiator 3, so that the light source that sends of the LED lamp plate 2 of bulb lamp can only shine the dead ahead of lamp.
With reference to shown in Figure 1, the described a kind of LED bulb lamp of the present embodiment, comprise lampshade 1, LED lamp plate 2, radiator 3, LED drive circuit plate 4 and lamp holder 5; Described lampshade 1 is connected with radiator 3, and LED lamp plate 2 is fixed on radiator 3 by screw 6, and the other end of radiator 3 is connected with lamp holder 5, and described LED drive circuit plate 4 extends in radiator 3 in lamp holder 5; Described lampshade 1 is the mushroom-shaped lampshade of inner hollow and tool radian.
Described lampshade 1 is transparent PC material lampshade.
Described lampshade 1 diameter is than the large 10mm of the diameter of radiator 3; The utility model adopts the mushroom-shaped lampshade, and the diameter of lampshade 1 makes bulb lamp except the dead ahead that shines lamp greater than the diameter of radiator 2, the reflective rear that can also shine lamp of lampshade inwall.
Described lampshade 1 passes through Elastic buckle with radiator 3.
Described LED lamp plate 2 is screwed in the top of radiator 3; LED lamp plate of the present utility model 2 positions, higher than the basic plane of radiator 3, can directly irradiate light to the rear of lamp.
Described radiator 3 is the fine aluminium radiator of cold forging die cast.
Described radiator 3 is provided with 40 fin, thereby has enlarged area of dissipation, has effectively improved radiating efficiency.
Described lamp holder 4 is screw socket.
According to the needs of practice, described lampshade 1 diameter in the present embodiment is than the diameter of radiator 3 any number in 5-15mm greatly; Described lampshade 1 also can be connected by snap close with radiator 3; Described lamp holder 6 can be bayonet socket.
The relatively existing LED illuminating product of the present embodiment, have more greatly and improve on lighting angle, greatly improved the optical efficiency of LED bulb lamp.
The announcement of book and instruction according to the above description, the utility model those skilled in the art can also carry out suitable change and modification to above-mentioned embodiment.Therefore, the utility model is not limited to the specific embodiment disclosed and described above, to modifications and changes more of the present utility model, also should fall in the protection domain of claim of the present utility model.In addition, although in this specification, used some specific terms, these terms just for convenience of description, do not form any restriction to the utility model.
