For the ease of understanding the utility model, below in conjunction with the accompanying drawings and specific embodiment, the utility model is carried out more detailed Thin explanation.It should be noted that when element is expressed " being fixed on " another element, it can be directly in another element Above or therebetween there may be one or more elements placed in the middle.When an element is expressed " connection " another element, it can To be directly to another element or there may be one or more elements placed in the middle therebetween.This specification is used Term " vertical ", " horizontal ", "left", "right" and similar statement for illustrative purposes only.

Unless otherwise defined, technology all used in this specification and scientific terminology are with belonging to skill of the present utility model The implication that the technical staff in art field is generally understood that is identical.In art used in the description of the present utility model in this specification Language is intended merely to describe the purpose of specific embodiment, is not intended to limit the utility model.Term used in this specification "and/or" includes the arbitrary and all combination of one or more related Listed Items.

The utility model embodiment provides a kind of LED lamp and lampshade, and the LED lamp may be used as garage lights, due to The U.S. has worked out specification for the performance of garage lights, as shown in figure 1,80 ° of light intensity angles 11 of the code requirement garage lights 10 The 30% of annulus luminous flux between 60 ° of scopes of light intensity angle 13 >=total output light flux, and allow minus 3% tolerance, moreover, car The 25% of annulus luminous flux between 80 ° of light intensity angles 11 of storehouse lamp 10 and 70 ° of scopes of light intensity angle 12≤total output light flux, and permit Perhaps positive 3% tolerance.

As illustrated in figs. 2-7, the lampshade 20 and led using the LED lamp 30 of the lampshade 20 that the utility model embodiment provides If in order to meet that the requirement of above-mentioned specification carries out innovative design.

Lampshade 20 uses Fresnel Lenses technical principle, specifically includes in the outer surface 21 of convex arc surface structure and in concave arc The inner surface 22 of surface structure, outer surface 21 are shiny surface.Inner surface 22 is integrally formed with the multiple band saws being coaxially set Tooth, that is to say, that multiple circular saws are shaped in the inner surface 22 of lampshade 20, and multiple circular saws have same axle Line 101.The opening 23 of circular saw towards lampshade 20 is obliquely installed, and opening 23 of the angle of circular saw along lampshade 20 to The direction of the bottom 24 of lampshade 20 gradually diminishes from big and becomes big from small, that is to say, that along the opening 23 of lampshade 20 to lampshade 20 Bottom 24 direction, then the angle of circular saw becomes big gradually from diminishing greatly from small.

For example, the angle of the circular saw 221 identified in Fig. 2 is 127 °, the angle of circular saw 222 is 112 °, The angle of circular saw 223 is 84 °, the angle of circular saw 224 is 81 °, the angle of circular saw 225 is 79 °, circular saw 226 angle is 73 °, it can thus be seen that the angle of circular saw 221 to circular saw 226 angle gradually from diminishing greatly； The angle of circular saw 227 is 82 °, the angle of circular saw 228 is 96 °, the angle of circular saw 229 is 113 °, band saw The angle of tooth 230 be 132 °, it can thus be seen that the angle of circular saw 227 to circular saw 230 angle again gradually from small Become big.The angle of circular saw can be 60 ° -140 °, and the angle of each circular saw can need to make according to practical application Slightly size changes.As shown in figure 3, by taking circular saw 221 as an example, in order to clearly show that circular saw 221, by circular saw 221 angle is identified as α, and angle [alpha] is by being opened in an inner surface of the annular V-groove 201 of inner surface 22 and being located at V-type What one inner surface of the annular V-groove 202 of the lower section of groove 201 was crossed to form.

In the utility model embodiment, referring again to Fig. 2, vertical range between adjacent two circular saws is along lamp Opening 23 to the direction of the bottom 24 of lampshade 20 of cover 20 tapers into, for example, between circular saw 222 and circular saw 223 Vertical range Vd1 be less than vertical range Vd2 between circular saw 221 and circular saw 222.

In the utility model embodiment, it is contemplated that the size of LED lamp 30 in actual applications is limited, and After LED light source determines, open diameter≤40cm of lampshade 20, ensure the illuminating area being sized for, reduce light pollution and subtract Few energy waste；In other embodiments, the open diameter of lampshade 20 can also be more than 40cm.

In order to play sheen effect, the inner surface 22 of lampshade 20 can use cloudy surface to handle so that be transmitted by lampshade 20 The light gone out is than milder, mitigation light pollution.

LED lamp 30 includes：Lampshade 20, lamp body shell 31 and LED light source module 32.Wherein, lampshade 20 and lamp body shell 31 is detachably connected, and LED light source module 32 is set located at the middle part of lamp body shell 31 and towards the inner surface 22 of lampshade 20.

In the utility model embodiment, for the ease of lampshade 20 is assembled into lamp body shell 31, to opening along lampshade 20 23 edges of mouth extend outward installation side 25, can be spaced on installation side 25 and open up multiple mounting holes 251, are easy to tight by screw thread Firmware is screwed in the mode of lamp body shell 31 after passing through mounting hole 251, and lampshade 20 is fixedly mounted on lamp body shell 31.In addition, In order to which the junction of lampshade 20 and lamp body shell 31 has certain waterproof action, annular waterproof trough can be provided with side 25 by installing 252, sealing ring 33 is embedded with annular waterproof trough 252.

In the utility model embodiment, LED light source module 32 includes lamp plate 321 and multiple LED on lamp plate 321 Lamp 322, LED 322 arrange in donut, improve the symmetry and uniformity for the light that LED 322 is sent.

It is real with 10 ° of the light intensity angle in interval under conditions of the power of LED lamp 30 is about 5322.0lm for 40W, luminous flux Border measurement is obtained such as the annulus light flux distribution in following table：

It can be calculated by above-mentioned list：First, annulus luminous flux of the light intensity angle between 60 ° of -80 ° of scopes accounts for hundred Point than being equal to 30.8%, i.e. 18.9%+11.9% summation, this 30.8% is more than the 30% of total output light flux；2nd, light intensity angle Annulus luminous flux between 70 ° of -80 ° of scopes accounts for percentage equal to 11.9%, and this 11.9% is less than total output light flux 25%.To sum up, the result actually measured meets above-mentioned code requirement.

In the utility model embodiment, for the more directive lampshades 20 of the light for sending LED 322, outside lamp body Reflector 34 is equipped with other regions of the place plane parallel of lamp plate 321 on shell 31, lamp plate 321 can also be reflector.

Under conditions of the power of LED lamp 30 is 40W, from the light flux distribution in polar coordinate system shown in Fig. 8 easily Go out, the highest luminance angle of LED lamp 30 is about 160 °, has larger irradiated area.

In the utility model embodiment, LED lamp 30 can also include：Network control module 35 and with network control The energy supply control module 36 that module 35 is electrically connected with, energy supply control module 36 are electrically connected with LED 322, network control module 35 are used for the control instruction that receives outside, and startup power supply control module 36 drives the LED 322 to work, to open illumination, just Remote control in realization to LED lamp 30.

A kind of LED lamp 30 and lampshade 20 that the utility model embodiment provides, wherein, lampshade 20 uses Fresnel Lenses Technology formed with：It is interior in convex arc surface structure and the outer surface 21 for shiny surface and the inner surface 22 in hollow cabochon structure Surface 22 is integrally formed with the multiple circular saws being coaxially set, the opening 23 of the angle of circular saw along lampshade 20 to bottom 24 direction gradually diminishes from big and becomes big from small, the light that LED light source module 32 is sent in lampshade 20 is to LED lamp 30 Carry out after specifically reflecting, irradiated area is big, has the preferable uniformity.
