Abstract
The utility model discloses a wide-angle light-emitting diode (LED) lamp which comprises a lamp head, a radiator, a base plate, an LED light source and a bulb shell. The lamp head is connected with the radiator which is connected with the base plate. The LED light source is arranged on the base plate. The bulb shell is connected with the base plate and covers the LED light source. An arc groove which is concaved inwards toward the wall of the bulb shell along the horizontal periphery of the bulb shell is formed in the inner wall of the bulb shell on the side periphery of the LED light source. According to the wide-angle LED lamp, the arc groove which is concaved inwards toward the wall of the bulb shell along the horizontal periphery of the bulb shell is formed in the inner wall of the bulb shell on the side periphery of the LED light source, the portion, with the arc groove, of the bulb shell is equivalent to a concave lens and has the effect of light scattering, when lateral light of the LED light source irradiates the arc groove, part of the irradiating light can deviate toward the direction of the lamp head, and accordingly the wide-angle LED lamp can guarantee the fact that a lighting angle is large enough.
Description
Technical field
The utility model relates to the LED lighting field, relates in particular to a kind of extensive angle LED lamp.
Background technology
At present, for the wide-angle that realizes the LED lamp luminous, industry is generally established a polyhedron in cell-shell, light source is arranged on the surface of these polyhedron different angles (as plane and vertical plane), though this method can reach bigger lighting angle, but still have following defective: the light emission direction of this LED lamp is for forward with towards side, therefore has only less light to shine the lamp holder direction of light fixture and structure relative complex.
The utility model content
The utility model provides a kind of can realize that the illumination of led light source is mapped to the LED lamp of the wide-angle uniformly light-emitting of lamp holder direction.
To achieve these goals, the solution that the utility model provides is: a kind of extensive angle LED lamp, comprise lamp holder, radiator, substrate, led light source and cell-shell, lamp holder is connected with radiator, radiator is connected with substrate, led light source is installed on the substrate, and cell-shell is connected with substrate and covers led light source; Inner wall around the side of described led light source is provided with along the deep-slotted chip breaker to cell-shell wall indent in a horizontal week of cell-shell.
Wherein, be provided with many described deep-slotted chip breakers that are parallel to each other in the described cell-shell uniformly.
Wherein, described cell-shell comprises the lower semisection cell-shell of columniform upper semisection cell-shell and sphere shape, and described deep-slotted chip breaker is arranged on the upper semisection cell-shell.
The beneficial effects of the utility model are: the extensive angle LED lamp that is different from prior art, a polyhedron is established in employing in cell-shell, light source is arranged on the surface of these polyhedron different angles, complex structure, brightness of illumination is inhomogeneous, extensive angle LED lamp of the present utility model, inner wall around the side of led light source is provided with along the deep-slotted chip breaker to cell-shell wall indent in a horizontal week of cell-shell, the cell-shell place that has deep-slotted chip breaker is equivalent to concavees lens, have the used of scattered light, when the illumination of led light source side direction is mapped to deep-slotted chip breaker, the feasible irradiation light of coming has part to the skew of the direction of lamp holder, make extensive angle LED lamp of the present utility model guarantee that the angle of irradiation is enough big, and simple in structure.

The specific embodiment
By describing technology contents of the present utility model, structural feature in detail, realized purpose and effect, give explanation below in conjunction with embodiment and conjunction with figs. are detailed.
See also Fig. 1, a kind of extensive angle LED lamp of present embodiment comprises lamp holder 1, radiator 2, substrate 3, led light source 4 and cell-shell 5, lamp holder 1 is connected with radiator 2, radiator 2 is connected with substrate 3, and led light source 4 is installed on the substrate 3, and cell-shell 5 is connected with substrate 3 and covers led light source 4; Cell-shell 5 inwalls around the side of described led light source 4 are provided with the deep-slotted chip breaker 6 to cell-shell wall indent along a horizontal week of cell-shell.Cell-shell 5 inwalls around the side of led light source 4 are provided with along the deep-slotted chip breaker 6 to cell-shell wall indent in 5 horizontal weeks of cell-shell, the cell-shell place that has deep-slotted chip breaker is equivalent to concavees lens, have the used of scattered light, when the illumination of led light source 4 side direction is mapped to deep-slotted chip breaker 6, the feasible irradiation light of coming has part to the skew of the direction of lamp holder, make extensive angle LED lamp of the present utility model guarantee that the angle of irradiation is enough big, and simple in structure.
In another is implemented, as shown in Figure 2, be provided with many described deep-slotted chip breakers 6 that are parallel to each other in the described cell-shell 5 uniformly, can further make so originally is that the extensive angle LED lamp of utility model is guaranteeing to have under the radiative situation of wide-angle, also makes emission photodistributed evenly.
In the various embodiments described above, described cell-shell 5 comprises the lower semisection cell-shell 52 of columniform upper semisection cell-shell 51 and sphere shape, described deep-slotted chip breaker 6 is arranged on upper semisection cell-shell 51, and columniform cell-shell can be saved the horizontal space of extensive angle LED lamp of the present utility model, the convenient use.
The above only is embodiment of the present utility model; be not so limit claim of the present utility model; every equivalent structure or equivalent flow process conversion that utilizes the utility model specification and accompanying drawing content to do; or directly or indirectly be used in other relevant technical fields, all in like manner be included in the scope of patent protection of the present utility model.
