Abstract
The utility model discloses a wide-angle LED lamp which comprises a lamp cap, a drive power source electrically connected with the lamp cap, a lamp body, a lamp panel and a bulb shell. The lamp panel is arranged on the lamp body and provided with an LED light source. The bottom of the bulb shell is connected with the lamp body. The top of the bulb shell forms a light reflecting face after being processed through coating or electroplating, and the center of the top of the bulb shell is pervious to light. In comparison with the prior art, the top of the bulb shell is processed through coating or electroplating so that the light reflecting face can be generated on the top of the bulb shell, and the light can be effectively reflected downwards. Meanwhile, the center of the top of the bulb shell is pervious to the light so that the light can be reflected directly, and therefore the needed wide angle is formed under the common effect of the reflection and the direct illumination. Furthermore, the thickness of a coating or an electroplating layer can be adjusted for achieving the uniformity of light distribution. The wide-angle LED lamp is low in cost, easy to assemble and less in light loss.
Description
Technical field
The utility model relates to the LED lighting technical field, particularly a kind of big-angle LED lamp.
Background technology
General LED bulb lamp is difficult to accomplish wide-angle, limit by the cell-shell shape, so angle is no more than 200 ° substantially.
Existing big-angle LED lamp design is generally the Polyhedral pedestal that a protrusion is set on radiator, and LED lamp pearl is attached on the aluminium lamp plate more than three or three, then the aluminium lamp plate is fitted on the different lateral of Polyhedral pedestal.Although this design can be done angle greatly, will be poor aspect heat radiation, because it dispels the heat sectional area ratio, general LED bulb lamp is little; Make in addition a plurality of aluminium lamp plates, can increase material cost, at assembling stage, also can increase assembly difficulty, thereby increased cost of labor.
The design that also has some existing big-angle LED lamps is that the mode of utilizing many bar-shaped LED or many strip substrates to erect reaches wide-angle, but the shortcoming of these designs is poor, the complex process of heat radiation; High-power, difficult production can't be accomplished, and the life-span can't be guaranteed.
The utility model content
The utility model is for above-mentioned the deficiencies in the prior art, provides that a kind of cost is lower, assembling is simple, light loss can increase the big-angle LED lamp of lighting angle again less simultaneously.
The technical solution of the utility model is achieved in that
A kind of big-angle LED lamp, the driving power, lamp body, lamp plate and the cell-shell that include lamp holder, be electrically connected with lamp holder, described lamp plate is arranged on lamp body, be provided with LED light source on lamp plate, the cell-shell bottom is connected with lamp body, the top of cell-shell forms reflective surface by coating or electroplating processes, and the center printing opacity at cell-shell top.
As preferably, the center at cell-shell top is inwardly recessed.Adopted such shape, thereby can conveniently at the cell-shell top, carry out coating or electroplating processes, cell-shell top center place can keep the nature printing opacity, need not adopt the operation of pickling to be processed cell-shell top center place again.
In order to optimize luminous intensity distribution, promote reflecting effect, as preferably, described lamp body is provided with the lamp socket that protrudes from the lamp body upper surface, and described lamp plate is arranged on the lamp socket end face.
As preferably, the opening part of described cell-shell is installed on the periphery of lamp body upper surface.
For convenience of dismounting, as preferably, described lamp plate is connected by screw with lamp body.
As preferably, the inside of described lamp body is hollow structure, and described big-angle LED lamp also comprises power shell, and driving power is arranged in power shell, and power shell is arranged in lamp body, and leaves gap between power shell and lamp body.Can make driving power not affected by the lamp body temperature.
In order conveniently to be dispelled the heat, as preferably, described lamp body is radiator, along the circumferential direction is provided with the fin of a plurality of vertical settings on the outer surface of radiator.
Compared to prior art, the utility model carries out coating or electroplating processes by the top to cell-shell, make the napex of cell-shell produce reflective surface, can effectively reflect light downwards, simultaneously, cell-shell top center place printing opacity, can make again light direct beam go out, the wide-angle that reflection and direct projection acting in conjunction form to need, further again can by the thickness of adjusting coating or plating realize luminous intensity distribution evenly, the utility model cost than low, assembling is simple, light loss is few.
Moreover, cell-shell of the present utility model top is inwardly recessed, thereby can conveniently at the cell-shell top, carry out coating or electroplating processes, form a reflecting surface that upright projection is annulus on horizontal plane, and cell-shell top center place can keep the nature printing opacity, need not adopt again the operation of pickling to be processed cell-shell top center place, can reach again the purpose of printing opacity when having saved operation, kill two birds with one stone.

The specific embodiment
The specific embodiment of the present utility model is as follows:
Embodiment: as Figure 1-4, the utility model big-angle LED lamp comprises lamp holder 1, driving power 6, lamp body 2, cell-shell 3, power shell 4 and the lamp plate 5 that is provided with a plurality of LED light sources 8.Described lamp body 2 is Aluminium Radiator or the radiator of being made by other materials such as heat-conducting plastic, potteries, and along the circumferential direction is evenly distributed with the fin of a plurality of vertical settings on the outer surface of lamp body 2.Described driving power 6 is arranged in power shell 4, and is electrically connected with lamp holder 1 and LED light source 8.
Be provided with the lamp socket 21 that protrudes from lamp body 2 upper surfaces on lamp body 2 tops, in the present embodiment, described lamp socket 21 outer contour shapes are cylinder, can be by adjusting its height, realize the optimization of luminous intensity distribution, lamp socket 21 is formed in one with lamp body 2, and lamp plate 5 is fixed on the end face of lamp socket 21, is evenly distributed with LED light source 8 on lamp plate 5.The opening part of described cell-shell 3 is installed on the periphery of lamp body 2 upper surfaces, and cell-shell 3 is connected by buckle with lamp body 2, and described lamp plate 5 is connected by screw 7 with lamp socket 21.
