Detailed description of the invention

With detailed description of the invention, the LED of the utility model first embodiment is described in further detail below in conjunction with the accompanying drawings.

Refer to Fig. 1, this LED 100 includes light source board 30, lens 20 and bulb housing 10, and this light source board 30 is arranged on The bottom of this bulb housing 10.Within these lens 20 are arranged on this bulb housing 10 and be positioned at the top of this light source board 30.These lens On 20 inwalls being integrally attached to this bulb housing 10, these lens 20 are to arranging by light source board 30.These lens 20 may be used for Being converging or diverging with the light that this light source board 30 sends, certainly, in the present embodiment, these lens 20 are used for dissipating this light source board 30 The light sent, to expand the lighting angle of whole lamp.This bulb housing 10 is made up of heat sink material, and this bulb housing 10 is not only to this Light source board 30 plays fixation, and after assembling, this light source board 30 is also played thermolysis by this bulb housing 10.

Refer to Fig. 1 to Fig. 2, these lens 20 are to rotate the rotary structure formed around the axis of this bulb housing 10.This is saturating Mirror 20 includes being arranged on the plane of incidence 25 of bottom and being arranged on the exit facet 26 at top, and the light that this light source board 30 sends passes through This plane of incidence 25 enters in these lens 20, and the exit facet 26 of these lens 20 is provided with reflecting part 21, and this reflecting part 21 is used for By the light that reflects from this plane of incidence 25 towards being partial to the bottom reflection of this bulb housing 10, more light thus can be made Line irradiates towards the bottom direction of this bulb housing 10, can expand the rising angle of this LED.This reflecting part 21 is by many strips Structure (not shown) is arranged in order formation around the center of this light source board 30, and the cross section of described every list structure is triangle Structure, and the external diameter of described every list structure is gradually reduced on the direction away from this light source board 30, so can increase light In the reflection efficiency of reflecting part 21, be conducive to improving the beam angle of this LED.

Refer to Fig. 1 to Fig. 2, this light source board 30 is provided with plurality of LEDs light source 31, and described LED light source 31 is around this light The center of source plate 30 is spaced ringwise, and the reflecting part 21 on this exit facet 26 is that corresponding described LED light source 31 is arranged Anchor ring, this reflecting part 21 this light source board 30 relative is obliquely installed, and is so conducive to this LED uniform in light emission and can increase this The rising angle of LED.

Refer to Fig. 1 to Fig. 2, this plane of incidence 25 is additionally provided with light collecting part 23, and this light collecting part 23 is for be arranged on this plane of incidence 25 Arc annuli arrangement, this light collecting part 23, for converging light towards this exit facet 26, also makes the reflecting part on exit facet 26 21 can reflect more light to this bulb housing 10 bottom direction, improve the rising angle of this LED.This light collecting part 23 For the cambered surface bulge-structure protruded out towards this light source board 30.The middle part of these lens 20 is additionally provided with perforation 24, and this perforation 24 connects The plane of incidence 25 of these lens 20 and exit facet 26, the ring that the diameter of this perforation 24 is formed less than the arrangement of described LED light source 31 Shape direct.So, by arranging this perforation 24, the partial heat produced when this light source board 30 works can allow this bulb housing Air within 10 forms convection current, with cross-ventilation form, partial heat is delivered to the top of this bulb housing 10, then by this bulb Shell 10 outwardly distributes.These lens 20 are arranged on the middle part of this bulb housing 10, these lens 20 and this bulb housing 10 link position The ratio of the length at place and the height of this bulb housing 10 is between 0.05-0.9.

Refer to Fig. 1 to Fig. 2, this bulb housing 10 has accepting groove 12 at these lens 20, after assembling, and this light source board 30 It is housed in this accepting groove 12.This light source board 30 is thermally coupled with this accepting groove 12, and this bulb housing 10 is made up of heat sink material. So, this light source board 30 is not only played fixation by this bulb housing 10, also this light source board 30 is played thermolysis.

Refer to Fig. 1 to Fig. 2, this bulb housing 10 includes two and half cell-shells 11, and this one of them sidewall of half cell-shell 11 is provided with Fitting recess 13, this another sidewall of half cell-shell 11 is provided with locating dowel 14, and after the docking of this two and half cell-shell 11 is closed up, this is fixed Position post 14 is housed in the fitting recess 13 of another half cell-shell 11 so that this two and half cell-shell 11 is relatively fixed, then with ultrasonic Ripple makes this two and half cell-shell 11 bond.

In sum, this LED is arranged on the inwall of this bulb housing 10 by this lens 20 one is connected, so, and can So that directly appearing from the side of this bulb housing 10 after the rays pass through lens 20 that sends of this LED light source 31, decrease light loss, Improve light extraction efficiency, but also eliminate and prior art needs volume optical lens device is set, thus this LED has knot The simple advantage of structure.It is additionally, since a part of light top of this bulb housing 10 of directive after this exit facet 26 penetrates, and another A part of light penetrates from the sidewall of this bulb housing 10 after being reflected by this reflecting part 21, this top just making this LED and deflection The bottom of lamp holder all has light to be distributed, thus it is luminous to realize wide-angle.Wherein, regulate these lens 20 to be connected with this bulb housing 10 The length of position and the ratio of the height of this bulb housing 10, can be increased or decreased emergent light from the sidewall of this bulb housing 10 The quantity of line.The light of the lowest outgoing of this ratio is the fewest.If it should be understood that to reduce the lighting angle of this LED, On the one hand need to change these lens 20 into collector lens, on the other hand need to reduce these lens 20 and this bulb housing 10 link position The length at place and the ratio of the height of this bulb housing 10.

The foregoing is only the utility model preferred embodiment, not in order to limit the utility model, all at the utility model Within spirit and principle, any amendment of being made, equal replacements, improvement etc., should be included in the scope that the utility model is protected Within.
