| 摘要 |
The invention relates to an LED module (1) which has a support (2), in particular a printed circuit board, at least one LED chip (3) which is applied onto the support (2) or is inserted into the support (2), and an optical element (4), preferably an optical plate which borders, preferably surrounds, a translucent area (5) provided above the LED chip (3). The optical element can have scattering particles. If this is the case, the concentration of the scattering particles can be higher in a region (43) which is aligned with the surface (30) of the LED chip (3), when seen in a main emission direction (H) that is preferably perpendicular to said surface, than in a region (44) which is not aligned with the surface (30) of the LED chip (3), when seen in the main emission direction (H). Alternatively or in addition to the scattering particle distribution which is concentrated in a controlled manner, at least one reflective element (6) can be provided on an optical element (4) face facing away from the LED chip (3) and at least in a surface region (41) which is aligned with the surface (30) of the LED chip (3), when seen in a main emission direction (H) that is preferably perpendicular to said surface, such that the emission of the LED chip (3) in the main emission direction (H) is evenly distributed preferably over the entire optical element (4). A homogenous light emission is achieved by means of the aforementioned embodiments. The invention further relates to a support (2) which has the aforementioned optical element (4), i.e. without the LED chip (3). |
