Description

Light source lamp set with detachable frame

The present invention relates to a lighting fixture, and more particularly to a light source lamp set with a detachable frame, which is provided with a light-transmissive sheet on a composite optical plate by a combined detachable frame. One side of the light sheet is decorated with a decorative pattern to add decorative lighting.

At present, the planar light source module is a widely used lighting device because of its better illumination and illumination area. Generally, the planar light source module is divided into two types by the light source used, and one of them is cold. The tube-type planar light source module of the cathode fluorescent tube (CCFL), and the LED type planar light source module including the light-emitting diode (LED). The general application of the lamp-type planar light source module is "direct light source" and "side light source", wherein the "side light source" can reduce the number of CCFLs installed in the planar light source module, thereby reducing the installation cost of the CCFL.

However, since the planar light source module using the CCFL as the light source is affected by the volume of the CCFL, and the entire planar light source module needs to have a large thickness space, the volume of the lamp-type planar light source module cannot meet the market. The mainstream demand is the demand for thin products today. Because LED has the characteristics of small size, light weight, long service life, high brightness, and low power consumption, the lighting fixtures that use LED as a light source gradually replace the lamp as the main light source of the lighting fixture, and the LED is Installed on the side of the light guide plate of the planar light source module, the light emitted by the LED is incident from the side of the light guide plate, and the light guide plate is matched with the reflector and the like, so that the light is emitted from the light exit surface through the continuous reflection and refraction. In order to provide the luminous effect of the planar light source and meet the requirements of thin products. The conventional side-light source is mainly provided with a light guide plate on a reflector, and an optical film such as a diffusion sheet and a light collecting sheet is disposed on the light guide plate, and the light is achieved by using a reflective polarizer (DBEF or CBEF). The purpose of concentration is to improve the problem of light reuse.

However, the application of the planar light source module to the lighting application today does not effectively and widely increase the application level of the planar light source module, but continuously improves the optical characteristics or the thin design of the planar light source module. However, commercial applications of planar light sources still have other commercial value for the public to use, not just for lighting purposes.

In view of the above, the present invention provides a light source lamp set with a detachable frame, which is characterized by a decorative pattern of a light-transmissive sheet, thereby increasing its flag, thereby increasing its application surface, such as: advertising billboards, warning signs, etc. application.
