Detailed description of the invention
Below by way of specific embodiment, the present invention will be described in detail:
Fig. 1 is the three-dimensional exploded view of first embodiment of the invention LED light device, and this LED light device 100 comprises upper cover 10, luminous intensity distribution portion 20, illuminating part 30, radiating part 40.This luminous intensity distribution portion 20 is slab structure, and according to the needs of different occasion, this luminous intensity distribution portion 20 can be cylindrical-shaped structure, truncated cone-shaped, the plate shape lens arrangements such as rectangle or square.This luminous intensity distribution portion 20 comprises incidence surface 21, exiting surface 23 and reflecting surface 22, this incidence surface 21 is arranged on the side in this luminous intensity distribution portion 20, this exiting surface 23 is arranged on the bottom surface in this luminous intensity distribution portion 20, the middle part in this luminous intensity distribution portion 20 is provided with groove or through hole 24, the side of this groove or through hole 24 forms this reflecting surface 22, and this reflecting surface 22 is for reflecting the most of light penetrated from this incidence surface 21 towards this exiting surface 23 and making these light penetrate after this exiting surface 23 reflects.Vertical or the substantially vertical setting mutually of this incidence surface 21 and this exiting surface 23.Certainly, for meeting specific luminous intensity distribution needs, also this incidence surface 21 can be formed slopely certain angle mutually with this exiting surface 23 and arrange.
Please refer to Fig. 1, this LED light device 100 comprises multiple illuminating part 30, and these illuminating parts 30 are spaced and just arrange this incidence surface 21.Each illuminating part 30 comprises at least one LED light source 31 and arranges the substrate of these LED light sources 31.The substrate of these illuminating parts 30 is integrally connected to form an annular base plate 32 mutually.This annular base plate 32 is made up of flexible material, and these LED light sources 31 are arranged on the medial surface of this annular base plate 32 at equal intervals.
Please refer to Fig. 1 to Fig. 4, the reflecting surface 22 in this luminous intensity distribution portion 20 is the reverse frustoconic globoidal structure (as shown in Figure 4) of this exiting surface 21 inclination relatively.The incidence surface 21 in this luminous intensity distribution portion 20 is globoidal structure, to being integrally formed with collector lens 211 by illuminating part 30 on the incidence surface 21 in this luminous intensity distribution portion 20, and the light that these collector lenses 211 send for converging this light out part 30 towards the middle part in this luminous intensity distribution portion 20.These collector lenses 211 are strip structure and are parallel to the axis setting in this luminous intensity distribution portion 20.These collector lenses 211 are trapezoidal list structure, this collector lens 211 comprises two sides 2112 and a plane of incidence 2111, this plane of incidence 2111 is just arranged this illuminating part 30, spacing between these two sides 2112 reduces gradually on the direction away from this luminous intensity distribution portion 20, the light that these two sides 2112 send for reflecting this illuminating part 30 towards this luminous intensity distribution portion 20.The middle part of this plane of incidence 2111 is provided with strip groove, and two sidewalls of this strip groove are used for reflecting towards these two sides 2112 respectively the light that this illuminating part 30 sends.
Please refer to Fig. 1, this radiating part 40 is set to annular solid and is connected to the outside of this illuminating part 30, and the lateral wall of this radiating part 40 is provided with multiple radiating fin 41.This upper cover 10 is arranged on the top in this luminous intensity distribution portion 20, and the bottom surface of this upper cover 10 is provided with reflector layer (not shown), and this reflector layer is not totally reflected and the veiling glare reflected for reflecting from this luminous intensity distribution portion 20.This upper cover 10 comprises a round panel 11 and is arranged on the hollow sleeve 12 at this round panel 11 center, and this sleeve 12 is socketed in inside this luminous intensity distribution portion 20.
During work, most of light that this illuminating part 20 sends enters this luminous intensity distribution portion 20 by incidence surface 21 refraction in this luminous intensity distribution portion 20, the reflecting surface 21 of this part light again in this luminous intensity distribution portion 20 reflexes to the exiting surface 23 in this luminous intensity distribution portion 20, and makes the injection after the refraction of this exiting surface 23 of these light.Compare traditional refraction-reflective lens, no longer just go out through the refraction of lens top and bottom perpendicular to the light near light-emitting area direction, therefore this luminous intensity distribution portion 20 overcomes plane of refraction to the poor shortcoming of light control ability, and making this luminous intensity distribution portion 20 incidence surface 21 converge most light by arranging bull collector lens 211, making light utilization reach more than 85%.Reduce the whole height in this luminous intensity distribution portion 20 simultaneously, this LED light device 100 overall volume is reduced, thinner shape can be set to.
In sum, LED light device 100 of the present invention is by arranging luminous intensity distribution portion 20 and arrange incidence surface 21, exiting surface 23 and reflecting surface 22 in this luminous intensity distribution portion 20, and after the light that illuminating part 30 is sent enters this incidence surface 21, major part reflects towards this exiting surface 23 and makes the injection after the refraction of this exiting surface 23 of these light.Not only optical efficiency is high for such LED light device, light distribution effect is good, and thicker lens need not be set as traditional lamp affixed to the ceiling, the volume of lamp affixed to the ceiling can be reduced, reduce costs, make this LED light device have the good and lower-cost advantage of light distribution effect.
The foregoing is only preferred embodiment of the present invention, not in order to limit the present invention, within the spirit and principles in the present invention all, any amendment made, equivalent replacement, improvement etc., all should be included within the scope of protection of the invention.
