Specific embodiment
With reference to the accompanying drawing, technical solutions of the utility model are described in detail.
As shown in Figure 1, a kind of lamp cap of the utility model embodiment, including the first light cover 1, the second light cover 2, light guide plate 3
With LED light strip 4.It is through-hole in the middle part of first light cover 1, is through-hole in the middle part of the second light cover 2.Preferably, the first light cover 1 and the second light cover
About 2 lay.The through-hole of the through-hole of first light cover 1 and the second light cover 2 is opposite.First light cover 1 is fixedly connected with the second light cover 2.
LED light strip 4 is fixedly connected with the first light cover 1 or the second light cover 2.Light guide plate 3 is between the first light cover 1 and the second light cover 2.
The edge of light guide plate 3 be embedded in the first light cover 1 and the second light cover 2, light guide plate 3 respectively with the middle through-hole of the first light cover 1 and
The middle through-hole of second light cover 2 is opposite.LED light strip 4 is opposite with the side of light guide plate 3.
The lamp cap of above-described embodiment, the light that LED light strip 4 issues are entered in light guide plate 3 by the side of light guide plate 3, then
Light is projected by light guide plate 3.It is through-hole in the middle part of first light cover, 1 middle part and the second light cover 2, light guide plate 3 is embedded in the first light cover 1
And second between light cover 2.Light guide plate 3 projects light by front and back simultaneously.The front of light guide plate 3 is face directed downwardly,
The back side is face upward.In the prior art, it projects in the front that whole light all passes through light guide plate 3.Plastics are usually arranged in the back side
Upper light cover, so that light can not project.The lamp cap of the present embodiment is through-hole in the middle part of the middle part of the first light cover 1 and the second light cover 2,
There is light injection in the front and back of light guide plate 3, meets the transparent lighting requirements of light guide plate 3, and increase environment
Brightness is conducive to protection human eye.
To increase brightness, as preference, as shown in fig. 6, the lamp cap further includes optics site 5, optics site 5
In the surface of light guide plate 3.Optics site 5 can be set in the front of light guide plate 3, also can be set at the back side of light guide plate 3.It is excellent
Optics site is imprinted on the surface of light guide plate 3 using laser mode by choosing.Optics site 5 changes the direction of side incident ray, makes
It obtains light guide plate 3 and forms the uniform area source that shines.When lamps and lanterns are desk lamp, it is preferred that at the back side of light guide plate 3, optical network is set
Point 5 increases the amount of light at 3 back side of light guide plate.About 3 light pass-through of light guide plate, it is anti-that the optical network point on light guide plate 3 plays light
The effect of penetrating.
Optics site 5 is set at the back side of light guide plate 3, the amount of light projected from 3 front of light guide plate can be increased, increased
The light efficiency projected from 3 front of light guide plate.Preferably, the density of optics site 5, from 3 Center wizard tabula rasa of light guide plate, 3 edge, by
It is decrescence small.For example, the density of optics site 5 are as follows: unit area (CM2) dot number is in 100~300 points, and from light guide plate 3
3 edge of Center wizard tabula rasa, density are gradually reduced.Preferably, the size of optics site 5, from 3 Center wizard tabula rasa 3 of light guide plate
Edge is gradually reduced.For example, the size of optics site 5 is 0.3~0.6mm, from 3 Center wizard tabula rasa of light guide plate, 3 edge, light
The size for learning site 5 is gradually reduced.Preferably, the depth of optics site 5, from 3 Center wizard tabula rasa of light guide plate, 3 edge, gradually
Increase.For example, the depth of optics site 5 is 0.03~0.15mm, and from 3 Center wizard tabula rasa of light guide plate, 3 edge, optics site
5 depth gradually becomes shallower as.Rationally density, size and the depth of setting optics site 5, can make light more evenly, softer.With
The light guide plate luminescence technology of the prior art is compared, and the lamp cap of this preference has the function of eyeshield, comfortable.
To increase the light efficiency projected from 3 front of light guide plate, as preference, as shown in fig. 7, the lamp cap further includes
Tabula rasa 6 and the reflective paper layer 8 of annular, the reflective paper layer 8 of annular are connected to the two sides of light guide plate 3, and light-transmitting plate 6 is located at annular reflective sheeting
