Embodiment Construction

[0011] Below in conjunction with accompanying drawing and specific embodiment the present invention is described in further detail:

[0012] The invention provides an illuminating device, which can adopt a non-rectangular light guide plate.

[0013] The lighting device of the present invention includes a circuit board, a light guide plate and a plurality of light-emitting components. The shape of the light guide plate is non-rectangular. The light-emitting component is arranged on the circuit board and electrically connected with the circuit board. The light emitting component surrounds the light guide plate, and the light emitting side of the light emitting component faces the light guide plate.

[0014] In one embodiment of the present invention, the shape of the light guide plate is circular, pentagonal, octagonal or irregular.

[0015] In one embodiment of the present invention, the light-emitting components are distributed point-symmetrically with the geometric center ...

Abstract

The invention relates to an illuminating device. The illuminating device comprises a circuit board, a light guide plate and a plurality of light emitting assemblies, wherein the light guide plate is in a non-rectangular shape; the plurality of light emitting assemblies are arranged on the circuit board, are electrically connected with the circuit board and surround the light guide plate; and the light emitting sides of the light emitting assemblies face the light guide plate. The illuminating device has the advantages that the light rays required by the light guide plate can be favorably supplied by only regulating the positions of the light emitting assemblies on the circuit board no matter what the shape of the light guide plate is, so that the cost of the illuminating device is lowered.

Description

technical field [0001] The invention relates to a lighting device, in particular to a light guide plate in the lighting device. Background technique [0002] In recent years, with the advancement of lighting technology, light source modules using light guide components and light emitting components have been gradually applied in many electronic products and lighting fixtures. Among various light emitting components, Light Emitting Diode (LED) has become the mainstream due to its high brightness, low power consumption and low pollution. However, if the shape of the light guide plate is unusually rectangular when using a side-illuminated light guide plate, how to arrange the light-emitting components on the light incident side of the light guide plate and arrange the power supply lines will be a difficult issue. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide an illuminating device aimed at solving the above probl...
