Detailed description of the invention
Fig. 1 is the exploded view of first embodiment of the invention big-angle LED lamp, this big-angle LED lamp 100 comprises multiple luminescence component 10 in concentric arrays and a body 20, and each luminescence component 10 comprises multiple LED light source 11 of circumferentially arranging and an annular luminous intensity distribution part 12.These LED light sources 11 are arranged on the end face of this body 20, and this luminous intensity distribution part 12 is arranged at the top of this LED light source 11.These LED light sources 11 can be common lighting angle at the LED light source of 10 degree to 180 degree, and the end face of axis this body 20 vertical of these LED light sources 11 and the distribution of light that they send respectively are symmetrically distributed in around this axis with the form of similar spot light.
Please refer to Fig. 1, this big-angle LED lamp 100 also comprises lampshade 30, and this lampshade 30 is for having the shell structure of opening, and this lampshade 30 is located at around these luminescence component 10 end faces.This lampshade 30 be positioned at this luminous intensity distribution part 12 top and and this luminous intensity distribution part 12 interval arrange.This lampshade 30 is provided with light diffusion material.The middle part of this lampshade 30 be slab construction and with the top surface being parallel of this body 20.
Please refer to Fig. 2 to Fig. 5, this luminous intensity distribution part 12 and this LED light source 11 interval arrange and are positioned at directly over this LED light source 11.This luminous intensity distribution part 12 is for reflecting the light of the central shaft near this LED light source 11 that this LED light source 11 sends towards the central shaft departing from this LED light source 11 towards the direction away from this body 20.Why this luminous intensity distribution part 12 is set like this, be because this LED light source 11 send more towards parallel and near wherein axis direction distribution of light, light intensity is larger.By the reflection of this luminous intensity distribution part 12, can by the light of script integrated distribution near the axis of this LED light source 11 with the distribution of larger angular spread, that is towards the directional spreding of central shaft departing from this LED light source 11.And so-called " direction away from this body 20 ", refer to that this luminous intensity distribution part 12 can not at the direction reflection ray towards this body 20.If towards the direction reflection ray of this body 20, the distribution of the light that this LED light source 11 sends towards its front will be reduced greatly, thus reduce light extraction efficiency.This point can be realized by the shape of the reflecting curved surface of adjustment luminous intensity distribution part 12.
The size of this luminous intensity distribution part 12 increases gradually on the direction away from this LED light source 11.This luminous intensity distribution part 12 comprises the first mirrored sides 121 and the second mirrored sides 122, this first mirrored sides 121 and this second mirrored sides 122 roughly divide the both sides of the central shaft being located at this LED light source 11, the setting that this first mirrored sides 121 and this second mirrored sides 122 tilt towards this LED light source 11, this first mirrored sides 121 and this second mirrored sides 122 light of the central shaft near these LED light sources 11 for reflecting this LED light source 11 respectively and sending.Please refer to Fig. 5 and Fig. 6, this first mirrored sides 121 and the similar "eight" shape structure of the present situation of the second mirrored sides 122 on cross section.
In the present embodiment, this first mirrored sides 121 and this second mirrored sides 122 are towards the recessed concave structure in the direction away from this LED light source 11.Why arranging like this is because we find, the effective both sides diffusing light towards this luminous intensity distribution part of this concave structure energy also avoids light to be reflected by the direction towards this body.Fig. 5 is the light path schematic diagram of this luminous intensity distribution part 12, the light of the central shaft near these LED light sources 11 that this LED light source 11 sends by this first mirrored sides 121 and this second mirrored sides 122 towards two lateral reflections away from central shaft, in addition, the some light of the central shaft away from these LED light sources 11 that this LED light source 11 sends can directly outgoing, and according to the needs of actual lighting angle, may correspond to this first mirrored sides 121 and this second mirrored sides 122 are set angle of inclination with the light reflected within the scope of different angles and realize different lighting angles.
Please refer to Fig. 2, Fig. 6, this luminous intensity distribution part 12 is to extending to form continuous print loop configuration by LED light source 11, this first mirrored sides 121 is towards the annular center reflection ray of this LED light source 11, and this second mirrored sides 122 is towards the direction reflection ray of the annular center away from this LED light source 11.Like this, not only light increases irradiating angle by reflection, and after passing through that these LED light sources 11 and this luminous intensity distribution part 12 are set to loop configuration, light illuminates the middle part of this body 20 through the reflection of this first mirrored sides 121, the periphery of this body 20 is illuminated, to realize comprehensive luminescence after the reflection of this second reflecting surface 122.Why select loop configuration, be because compared by the light major part that this luminous intensity distribution part 12 reflects the both sides being evenly distributed in this luminous intensity distribution part 12, be difficult to realize uniform Light distribation from the place away from this luminous intensity distribution part 12.Further, these luminescence components 10 comprise the first luminescence component 101 and the second luminescence component 102, this second luminescence component 102 is located at the periphery of this first luminescence component 101 and is formed concentric structure with this first luminescence component 101, like this, light in the middle part of this body 20 can be strengthened to avoid occurring that dark space realizes better Light distribation, in fact can arrange multi-turn luminescence component according to inside and outside the requirement of luminous intensity.
In sum, this big-angle LED lamp 100 is provided with this luminous intensity distribution part 12, this luminous intensity distribution part 12 is for reflecting the light of the central shaft near this LED light source 11 that this LED light source 11 sends towards the central shaft departing from this LED light source 11 towards the direction away from this body 20, like this, the light of the smaller angle that this LED light source 11 sends is after the luminous intensity distribution of this luminous intensity distribution part 12, lighting angle is increased to two lateral reflections, make whole lamp can realize the luminescence of greater angle, directly make beam projecting to obtain the illumination effect of larger angle compared to traditional LED spotlight, luminous intensity distribution is carried out owing to adopting the reflection of this luminous intensity distribution part 12, this big-angle LED lamp is made to have the large advantage of rising angle.
