Description

LEDbulb lamp

Technical field

The utility model belongs to lighting field, particularly a kind of LEDbulb lamp.

Background technology

Conventional incandescent power consumption is high, the life-span is short; under the overall situation of global resources anxiety; gradually, forbidden producing by national governments; substitute products are electronic energy-saving lamps thereupon; although electronic energy-saving lamp improves energy-saving effect; but owing to employing the heavy metal element of many contaminated environment, run counter to again the main trend of environmental protection.Along with the high speed development of LED technology, LED illumination becomes the only choosing of novel green illumination gradually, LED is far superior to traditional lighting products in the aspect of principle of luminosity, energy-saving and environmental protection, so LEDbulb lamp is the novel green light source of alternative conventional incandescent bulb.In commercial market, it is LEDbulb lamp comparatively widely that LED illumination product uses, LEDbulb lamp is in the market divided into pears type and G type, as its name suggests, observing bulb lamp from the luminous top of bulb is be all circular substantially, no matter total any angle is set out, and all be unable to do without the moulding of conventional incandescent.It is single that this traditional pyriform bulb lamp also exists moulding, shortcoming attractive in appearance not, simultaneously because light emitting source is often placed in the home position of pyriform moulding by existing bulb lamp, make light just direct projection and going out after cell-shell, formed and dazzle the eyes and dazzling light, the illuminating effect under home environment is soft not.

Utility model content

The purpose of this utility model is to provide a kind of LEDbulb lamp, and it has handsome in appearance, and the advantage that light is soft.

To achieve these goals, the technical solution adopted in the utility model is as follows: LEDbulb lamp, comprise the lamp holder, radiator, LED and the cell-shell that connect successively, described LED is installed on one end of described radiator, described radiator inside is provided with driving power, arbitrary cross section of described cell-shell is by four identical end to end compositions of camber line, and the camber line being in relative position is symmetrical set, and the radius of described camber line is greater than the distance between described camber line mid point and described cell-shell axis.

Preferably, connected by transition arc between described adjacent camber line, described transition arc and described adjacent tangential, and the radius of described transition arc is less than the radius of described camber line.

Preferably, the described radius often organizing transition arc between adjacent camber line is all equal.

Preferably, the central angle of described transition arc is less than the half of described camber line central angle.

Preferably, the central angle of described camber line is not less than 50 degree.

Preferably, described LED comprises many array arrangements in the great power LED of described radiator one end.

LEDbulb lamp of the present utility model, the moulding of cell-shell is designed especially, make its arbitrary cross section by four identical end to end compositions of camber line, the camber line being in relative position is symmetrical set, and the radius of described camber line is greater than the distance between described camber line mid point and described cell-shell axis, each cross section of cell-shell just forms the closed curve of a squarish, the cell-shell of the some cross section compositions gradually changed by size, its external styling is also visually squarish in entirety, and each sideline is curved, such moulding is not only attractive in appearance, and illuminator is not overlapping with the center of circle of each camber line, therefore light can reflect through cell-shell, make the light after refraction towards multiple different direction, form light at random, therefore illuminating effect seems softer and not dazzling.

Detailed description of the invention

Below in conjunction with accompanying drawing and embodiment, the technical solution of the utility model is described.

As shown in Figure 1, Figure 2 and Figure 3, the utility model is a kind of LEDbulb lamp, comprise the lamp holder 10, radiator 20, LED 30 and the cell-shell 40 that connect successively, described LED 30 is installed on one end of described radiator 20, described radiator 20 inside is provided with driving power 50, arbitrary cross section of described cell-shell 40 is by four identical end to end compositions of camber line 41, the camber line 41 being in relative position is symmetrical set, and the radius R of described camber line 41 is greater than the distance L between described camber line 41 mid point and described cell-shell 40 axis.LEDbulb lamp of the present utility model, the moulding of cell-shell 40 is designed especially, make its arbitrary cross section by four identical end to end compositions of camber line 41, the camber line 41 being in relative position is symmetrical set, and the radius R of described camber line 41 is greater than the distance L between described camber line 41 mid point and described cell-shell 40 axis, each cross section of cell-shell 40 just forms the closed curve of a squarish, the cell-shell 40 of the some cross section compositions gradually changed by size, its external styling is also visually squarish in entirety, and each sideline is curved, such moulding is not only attractive in appearance, and illuminator is not overlapping with the center of circle of each camber line 41, therefore light can reflect when cell-shell 40, make the light after refraction towards multiple different direction, form light at random, therefore illuminating effect seems softer and not dazzling.

In order to make the edge of cell-shell 40 seem mellow and full while, cell-shell 40 is moulded to be drawn close to square, connected by transition arc 42 between described adjacent camber line 41, described transition arc 42 is tangent with described adjacent camber line 41, and the radius of described transition arc 42 is less than the radius of described camber line 41, make camber line 41 form four sidelines of " square ", and transition arc 42 only make the connection between camber line 41 seem level and smooth.So, cell-shell 40 more seems that circumference combines on the whole, improves the aesthetic measure of moulding.

In addition, the described radius often organizing transition arc 42 between adjacent camber line 41 is all equal, and make the transition arc 42 also identical stock size of each edge on cell-shell 40 cross section, therefore the moulding of cell-shell 40 also becomes symmetrical moulding, improves aesthetic property.

In order to make the moulded squarish that more seems of cell-shell 40, the central angle of described transition arc 42 is less than the half of described camber line 41 central angle, and preferably the central angle of described camber line 41 is not less than 50 degree, the angle that such transition arc 42 takies is less, the angle that camber line 41 takies is larger, also four sidelines of " like square " are namely made up of closely arc, and transition arc 42 is only be equivalent to the rounded corners between four sidelines, so just, cell-shell 40 can be made more to seem squarish, not only can improve the aesthetic property of LEDbulb lamp, also the soft effect of illuminating ray can be improved.

In addition, described LED 30 comprises many array arrangements in the great power LED of described radiator 20 one end, can improve brightness of illumination.

The utility model has handsome in appearance, and the advantage that light is soft.
