Problems solved by technology

For example, this can degrade the appearance and / or performance of the light engine covered by the central region of the elastomeric molding, giving the light engine a matte appearance and reducing the clarity of the molding
Attempts to clean the elastomeric molding can cause such dust particles to be scratched or pressed into the central area of ​​the elastomeric molding that serves as the light exit window of the light engine, which perpetuates this deterioration

Embodiment Construction

[0028] It should be understood that the drawings are only schematic and not drawn to scale. It should also be understood that the same reference numbers are used throughout the drawings to indicate the same or similar parts.

[0029] figure 1 An apparatus 10 and its method of providing moldings on the apparatus 10 are schematically depicted according to one embodiment of the invention. Such as figure 1 As shown in , device 10 has components 15 including housing 20 housing light engine 21 . Housing 20 is generally a separate module that is assembled into device 10 in any suitable manner. As a non-limiting example, housing 20 is shown inserted into an aperture within component 15, but it should be understood that the manner in which housing 20 is assembled into component 15 is not critical to the invention. Housing 20 may be assembled into device 10 in any suitable manner. Similarly, component 15 may be any suitable part of device 10, such as a device housing, carrier, et...

Abstract

Disclosed is a device (10) comprising a housing (20) including a light engine (21), said housing contacting a part (15) of the device; and an elastomer moulding (30) over said housing, said elastomermoulding comprising a cured central region (31') acting as a light exit window for light emitted by said light engine and an uncured peripheral region (33) around said central region, said peripheralregion contacting said part and acting as a seal. The cured central region has a greater hardness than said uncured peripheral region. Also disclosed is a method of moulding such a device in this manner.

Description

technical field [0001] The invention relates to a device comprising a housing having a light engine and an elastomeric molding over said housing, said housing being fitted in or on a part of the device; and said elastic The body molding comprises a central region surrounding said central region, the central region serving as a light exit window for light emitted by said light engine, said peripheral region contacting said component and acting as a seal. [0002] The invention also relates to methods of sealing such devices with such elastomers. Background technique [0003] Today, many devices (eg, electronic devices such as home appliances, portable electronic devices such as smartphones, tablets, etc., or lighting devices) include one or more light engines such as LEDs. Such a light engine may be used to provide functional or aesthetic illumination of an area of ​​interest, or may be used as an indicator of a device, for example to indicate the functional mode of the devi...
