Embodiment Construction

[0012] The present invention will be described in detail below in conjunction with the accompanying drawings.

[0013] Fig. 1 is a schematic diagram of an exploded structure of the first embodiment of the present invention. What is shown in the figure is an embodiment of the present invention in which the light guide plate is a cylindrical surface, and the backlight pattern is a linear pattern, with light incident from one side.

[0014] As shown in FIG. 1 , the present invention includes a cylindrical light guide plate 11 on which a light guide pattern 12 is arranged. LED groups 13 are incident with light from the side of the light guide plate and connected to a power source 14 . When the present invention works, the LED group 13 incident light from the side of the light guide plate makes the light guide pattern on the cylindrical light guide plate emit light, forming a surface light source with two cylindrical light emitting surfaces inside and outside. Wherein, the inner l...

Abstract

A curved light source being formed by curved light guide plate and being used on illumination lamp is prepared as setting light guide pattern on lightening surface of curved light guide plate, connecting light source to power supply, setting said light source at side surface at periphery on light guide plate and utilizing said side surface to lead light in further more applying parallel-connected LED set as incoming light source of light guide plate.

Description

technical field [0001] The invention relates to a curved light source for illuminating lamps composed of a curved light guide plate. Background technique [0002] At present, the surface light source of the light guide plate is only used in the backlight source, and has not been used in general lighting fixtures. Moreover, because it is used in the backlight source, its shape can only be flat. [0003] Moreover, currently large-area light guide plates mostly use fluorescent tubes as light sources, which may cause hazards such as "strobe flicker" and AC radiation and contain harmful substances "mercury" when used for lighting. [0004] The application of lighting products is more flexible than the application of backlights such as displays or advertising light boxes, both in terms of installation methods and appearance. Especially the shape, a simple planar light source cannot meet the requirements in many cases. Contents of the invention [0005] Aiming at the shortcomin...
