Embodiment
The utility model is described further below in conjunction with the drawings and specific embodiments.
With reference to Fig. 1-5, a kind of LED flexible surface light sources, including：LED/light source 11 and light the reflection dress being arranged on substrate 1
Put 2；
Relative to the slant setting of LED/light source 11, shape has angle the light reflection unit 2 therewith；So that described
The light portion that LED/light source 11 is sent reflects by light reflection unit 2, partly reflects the transmission of 2 devices by light.Due to anti-
The direction for penetrating light and transmitted light is differed, therefore the light that LED/light source 11 is sent entered reflection and was formed face light after transmiting
The illumination effect in source.
The concrete structure of the present embodiment is as described below：The light reflection unit 2 includes a flexible base board 21, its lower surface
Side be fixedly connected with substrate 1, opposite side set a speculum 22；It can pass through tin between the flexible base board 21 and substrate
Cream, which is welded, or glue is viscous sticks to achieve a fixed connection.
The flexible base board 21 sets the part of speculum 22 to be folded upward at relative to the part being fixedly connected with substrate 1,
The angle is formed with the LED/light source 11.This is simple for structure, needed for effectively uniform area light source is realized in reduction
The thickness wanted, greatly reduces the integral thickness of LED flexible surface light sources.
Further, in order to realize speculum 22 transmit light can pass through flexible base board 21, the flexible base board 21
Upper surface and the corresponding position of the speculum 22 be additionally provided with least one loophole 211 for running through flexible base board 21.This reality
Apply in example, loophole 211 is circular hole, and quantity is 4, in 2X2 array distributions.It is to be appreciated that the need for according to light-out effect,
The shape of loophole 211 can be arranged to the other shapes, the number of the loophole 211 such as oval or rhombus in other embodiments
Amount and pore size can also be adjusted according to actual needs.
As a result of flexible base board 21, and one end that flexible base board 21 is bent is free end, in order to increase its stability
And anti-pressure ability so that the rising angle of light keeps stable.The upper surface of the substrate 1 coats one layer of layer of silica gel 12；It is described
Layer of silica gel 12 coats the flexible base board 21 and speculum 22 completely.Thus flexible base board 21 and speculum 22 are formd
Support so that the position of flexible base board 21 is not susceptible to movement, it is ensured that the stability of beam projecting angle, and the height of silica gel is saturating
Photosensitiveness ensure that exiting light beam intensity will not because add layer of silica gel 12 and by king-sized influence.
It is described in order to further increase the rising angle of the emergent ray after layer of silica gel and the uniformity of light distribution
One side of the layer of silica gel 12 away from the substrate 1 is also sticked one layer of light guiding film 121.The upper surface of the light guiding film 121 passes through hot pressing
Technique array sets optics site 122.Optics site 122 effectively can reflect the light for being totally reflected into light guiding film 121
Go out the surface of light guiding film 121.
Preferred embodiment of the present utility model is the foregoing is only, should not to limit the utility model
Point out, on the premise of the utility model is not departed from, any modification, equivalent substitution and improvements made etc. should be included in this reality
Within new protection domain.
