Detailed description of the invention
Below in conjunction with drawings and Examples, the specific embodiment of the present invention is done further in detailDescribe. Following examples are used for illustrating the present invention, but are not used for limiting the scope of the invention.
The lens of the present embodiment as shown in Figure 1, comprise at least two-layer hyaline layer, and hyaline layerDensity is successively decreased successively. The signal that comprises the first hyaline layer 1 and the second hyaline layer 2 has been shown in Fig. 1Figure. The lens of the present embodiment comprise multi-layer transparent layer, and density successively decreases successively, as arrow in Fig. 1Shown in head, when light is from the large little hyaline layer of hyaline layer directive density of density, dispersion angle is larger,And do not need to increase light source and lens shape is done to too much design, therefore cost is lower.
Between hyaline layer, can connect by viscose glue, also can fix by frame, make between hyaline layerClose contact.
In the present embodiment, the mid point of all hyaline layers is on same straight line, and bright dipping can like thisDisperse more towards periphery.
In order further to promote the dispersion effect of light, promote the light uniformity, at least one is saturatingBright layer forms the structure of central concave, as shown in Figure 2, and outermost by the lens in Fig. 1Hyaline layer has formed the structure of central concave.
Varying in size of the former material particle of the material of every layer of hyaline layer, to realize different density.Each hyaline layer forms by an injection moulding, also can adopt different former materials, different particle sizeMaterial just form the hyaline layer of different densities by Multi-step injection molding. Particularly, comprise two-layerBright layer: the first hyaline layer 1 and the second hyaline layer 2. The two-layer hyaline layer number of plies is less, and light obtainsDisperse preferably, and easy to make, cost is low, transmitance is high.
The material of hyaline layer can be PMMA (polymethyl methacrylate), PC (poly-carbonic acidEster), any one or several combination in PET (PET), everyThe material injection moulding that layer of transparent layer adopts above-mentioned one or more materials to be mixed into by different proportionForm, ratio different densities is also different.
The present invention also provides a kind of lighting device, comprising: pcb board, be arranged on pcb boardOn light source and cover the described lens of light source, and press the transmit direction of light, the density of hyaline layerReduce successively, the circuit on described pcb board is used for driving described light source luminescent.
Particularly, a kind of lighting device of the present invention as shown in Figure 3, comprising: pcb board 110,Be arranged on the light source 120 on pcb board 110, all hyaline layers 130 and 140 of described lensBe hemispherical and be buckled on described pcb board 110 to form spatial accommodation, described light source 120Be arranged in described spatial accommodation.
