Embodiment Construction

[0029] see Figure 4 , which is a schematic diagram of the first preferred embodiment proposed by the present invention. The first preferred embodiment is a light emitting device 400 including a plurality of light emitting units 41 , a plurality of reflective cups 42 and an optical lens device 43 . The optical lens device includes a first lens 431 , a second lens 432 and a third lens 433 , wherein the first lens 431 is a main lens, and the second lens 432 and the third lens 433 are secondary lenses. The first lens 431 has a first optical axis 4311 , a first luminous optical axis 4312 and a first luminous field type 4313 , wherein the first optical axis 4311 coincides with the first luminous optical axis 4312 . The second lens 432 has a second optical axis 4321, a second luminous optical axis 4322 and a second luminous field type 4323, wherein the second lens 432 has a difference between the second optical axis 4321 and the second luminous optical axis 4322 The second include...

Abstract

The invention provides an optical lens device. The optical lens device comprises a main lens and at least one secondary lens, wherein the main lens is provided with a first symmetric axis and a first optical axis, and the first symmetric axis is superposed with the first optical axis; and the at least one secondary lens is provided with a second symmetric axis and a second optical axis, the at least one secondary lens is arranged on four sides of the main lens, and the second symmetric axis is superposed with the second optical axis, wherein the main lens and the at least one secondary lens produce a uniform luminous field.

Description

technical field [0001] The present invention relates to an optical lens device, in particular to an optical lens device with a tilted lens. Background technique [0002] With the rise of environmental protection awareness such as energy saving and carbon reduction, lighting tools in daily life are also developing towards the trend of high efficiency and low power consumption. For example, lighting fixtures using light-emitting diodes (LEDs), which have the advantages of small size, long life, low power consumption, fast response, and good shock resistance, have attracted much attention in recent years. However, because the light of LEDs has directivity and the characteristics of point light sources, it is necessary to install additional optical lenses to reduce its directivity when it is applied to lighting fixtures other than light-gathering purposes, so that it is suitable for lighting purposes. However, due to the structure of the existing optical lens, even if the direc...
