Detailed description of the invention
Below by specific embodiment, the utility model is elaborated:
Fig. 1 is the decomposing schematic representation of the utility model the first embodiment mirror lens formula LED lamp, this mirror lens formula LED lamp 100 comprises bulb housing 10, body 20, substrate 30, lens 40, the bottom surface of these lens 40 is arranged on this substrate 30, this bulb housing 10 covers on this body 20, this bulb housing 10 was hemisphere cell-shell, and this bulb housing 10 is provided with printing opacity scattering material.
Please refer to Fig. 2, this substrate 30 is planar structure, and this substrate 30 is provided with the first LED light source 31 and the second LED light source 32, and this first LED light source 31 and the second LED light source 32 comprise respectively plurality of LEDs light source.LED light source in these first LED light sources 31 is respectively around peripheral rounded being arranged on this substrate 30 of these lens 40, and this radius of circle is greater than the maximum radius of this lens 40 projection on this substrate.Make these lens 40 can not block the light that this first LED light source 31 sends to this bulb housing top.
Please refer to Fig. 2 to Fig. 4, these lens 40 are two-part structure, the lateral surface on these lens 40 tops forms bright dipping side 42, the middle part of these lens 40 end faces is recessed to form reflecting surface 41(as shown in Figure 2 towards this substrate 30), this reflecting surface 41 near the cambered surface at these lens 40 middle parts (being axis) towards protruding out away from these bright dipping side 42 directions, the middle part of this bright dipping side 42 is towards protruding out away from the direction of this reflecting surface 41, and this bright dipping side 42 forms ring-type convex lens structures (as shown in Figure 1) with this reflecting surface 41.The bottom of these lens 40 is provided with accepting groove 44, and this accepting groove 44 is opened in the bottom surface of these lens 40.This accepting groove 44 is cylindric, and in these lens 40, the external diameter on the top at 42 places, bright dipping side is greater than the external diameter of the bottom at these accepting groove 44 places.The top of this accepting groove 44 is incidence surface 43, and these second LED light sources 32 are arranged in this accepting groove 44, and this incidence surface 43 is positioned at the top of these the second LED light sources 32.The middle part of this incidence surface 43 is towards being recessed to form globoidal structure (as shown in Figure 3) away from the direction of these the second LED light sources 32, this incidence surface 43 more reflects towards this reflecting surface 41 for the light that this second LED light source 32 is sent.This reflecting surface 41 reflects towards this bright dipping side 42 for the most of light that these second LED light sources 32 is sent and passed through this incidence surface 43 and reflect.This incidence surface 43 towards protruding out away from the direction of this reflecting surface 41, forms ring-type convex lens structures to coordinate with this reflecting surface 41 near the cambered surface at middle part.Due in lens, thicker part distribution of light is more, so this ring-type convex lens structures can make the light that this second LED light source 32 sends more reflect towards this reflecting surface 41.
When work, first, the light that these first LED light sources 31 send does not pass through lens, shines directly into the top of this bulb housing 10.Secondly, when the light that these second LED light sources 32 send incides on the reflecting surface 41 of these lens 40, by the setting of these reflecting surface 41 cambered surfaces, most of light will produce total reflection on the reflecting surface at these lens 40 41, because this reflecting surface 41 forms ring-type convex lens structures with this bright dipping side 42, the light that total reflection is returned like this can be to the larger position outgoing of convex lens structures thickness, and because the effect of the converging light of convex lens is irradiated by the bottom of backward this bulb housing 10 of these exiting surface 42 outgoing, illuminate the bottom of this bulb housing 10.Like this, because top and the bottom of this bulb housing 10 are all illuminated, can realize omnibearing luminous.Why make this incidence surface 43 form convex lens structures with this reflecting surface 41, object is to make the light that these second LED light sources 32 send can more be injected into the middle and upper part of this reflecting surface 41 and total reflection occurs.The light that these first LED light sources 31 and the second LED light source 32 send, through the diffusion of this bulb housing 10, makes this mirror lens formula LED lamp 100 realize Omnibearing even luminous.Fig. 5 is the distribution curve flux figure of this mirror lens formula LED lamp 100, and from this distribution curve flux, it is luminous that this mirror lens formula LED lamp 100 can be realized more than 300 degree wide-angle.
In sum, the utility model mirror lens formula LED lamp 100 is provided with the first LED light source 31 and the second LED light source 32, these first LED light sources 31 are arranged at these lens 40 peripheries and directly illuminate top and the sidewall of this bulb housing 10, the light that these second LED light sources 32 send is through these lens 40, realize the control to light incident and exit direction by these lens 40, to illuminate the bottom of this bulb housing 10, like this, make whole lamp reach the luminous effect of Omnibearing even, due to without LED module is fixed on multiple inclined-planes, this mirror lens formula LED lamp 100 is also had advantages of simple in structure.In addition, the light sending due to these first LED light sources 31 directly scatters out from this bulb housing 10 without lens, makes this mirror lens formula LED lamp 100 also have higher optical efficiency.
Understandable, for not obstructed the light by these lens 40, the edge that these second LED light sources 32 can be arranged in this substrate 20 approaches this bulb housing 10 places.Preferably, can also on this reflecting surface 41, be provided with reflector layer (not shown), this reflector layer (not shown) is for reflecting light towards this bright dipping side 42.This incidence surface 43 can be plane.
The foregoing is only preferred embodiment of the present utility model; not in order to limit the utility model; all within spirit of the present utility model and principle, any amendment of making, be equal to replacement, improvement etc., within all should being included in the scope of the utility model protection.
