摘要:
A lens configured to a lighting device, comprising an optical part (1) and a mechanical part (2) surrounding the optical part (1), wherein, the mechanical part (2) comprises a blocking protrusion (3) protruding in a direction parallel to the optical axis (4) of the lens, surrounding the optical part (1) and spaced apart from the optical part (1). This type of lens can effectively prevent the optical part from being damaged, for example, in a low pressure molding process, by a hot liquid glue, improve the yield of the lighting device, and have fine waterproof ability at the same time. Also disclosed is a lighting device having this type of lens, and the lighting device has beautiful appearance and fine waterproof effect. A method configured to make this lighting device is also disclosed.

A lens having a first surface (1) and a second surface (2). The first surface (1) and the second surface (2) are mirror symmetric to a first symmetric plane (A) passing through an optical axis (Y) of the lens and extend in a first direction (X) perpendicular to the optical axis (Y). The curve profiles of the first surface (1) and the second surface (2) on the cross sections perpendicular to the first direction (X) are configured in such a way that light emitting from a light source (3) arranged at a predetermined position of a second surface side is refracted by the first surface (1) and the second surface (2) to be emitted in a direction which is offset from the optical axis (Y) by more than a predetermined angle.

The present invention relates to a light emitting module, comprising: a PCB board (1); a light emitting assembly (2) mounted on the PCB board (1); a lens (3) and an encapsulating housing (4), the encapsulating housing (4) encapsulating therein the PCB board (1), the light emitting assembly (2) and part of the lens (3), and an exit surface (5) of the lens (3) being exposed out of the encapsulating housing (4), wherein, the encapsulating housing (4) is formed therein with a first concave region (6) surrounding the exit surface (5) and reducing light blocking, and at least a second concave region (7) into the first concave region (6), wherein, the second concave region (7) is designed in such a way that water in the first concave region (6) is drained via the second concave region (7).
摘要:
An encapsulation housing for a LED module has an upper housing (1) and a lower housing (2) joined together and defining together a cavity, wherein at least one of the upper housing (1) and the lower housing (2) has an inner partition wall partitioning the cavity into an assembly cavity (3) and an anti-leakage cavity (4) encircling the assembly cavity (3). By using the encapsulation housing according to the present invention for encapsulating the LED module, potting glue is pot into the assembly cavity (3). During a potting process, the potting glue possibly leaking out from the inner partition wall flows into the anti-leakage cavity (4) rather than out of the encapsulation housing. In addition, the present invention also relates to an LED module with the above type of encapsulation housing.
