Reflective illuminating device

The present invention relates to a lighting device, and more particularly to a reflective lighting device.

Generally, a light-emitting element, such as a light-emitting diode, is a point light source. For the development of a surface light source, the higher the brightness of the light-emitting element, the higher the light-emitting intensity of the center portion, making the uniformity of the surface light source more difficult, even through the firefly. The light conversion of the toner layer or the adjustment by the secondary optics, when viewed from the outside of the light-emitting device, the light emitted from the light-emitting element is stronger in the central portion than in the surroundings. Therefore, in the case of using a light-emitting element in combination and for uniformly emitting light, in general, a light guide plate is used as a medium for uniform light emission, but the larger the light-emitting area, the more the brightness deviation is accompanied, so that the signboard and the outdoor are A relatively large advertising information billboard such as a kanban is projected into a light source by arranging a plurality of point light sources.

Further, the light source used in the conventional advertisement information billboard is a halogen lamp or a discharge lamp. For example, as shown in FIG. 1, the light-emitting device 101 is disposed obliquely below the front side of the signboard 100, and the light emitted from the light-emitting device 101 is used to illuminate the signboard. The illuminated surface (surface) 102 of 100 is an external illumination device 103. The light-emitting device 101 for the external illumination type illumination device 103 reflects the illumination light from the light source 104 by the reflection member 106 mounted inside the casing 105, and is refracted by the light source 104 by the lens 107. The light emitted and the reflected light that has been reflected by the reflecting member 106 are emitted, and the light emitted from the light source 104 and the reflected light from the reflecting member 106 are irradiated onto the illuminated surface 102 by the lens 107. This applies to advertising information, including elections, housing, or art activities.

However, in the conventional lighting device, the structure of the illuminating device is complicated and the number of parts is large, so that the price of the product in which the illuminating device is installed is repeatedly increased due to the material price, and at the same time, the structure cannot meet the space saving requirement. Moreover, since the conventional lighting device uses a halogen lamp or a discharge lamp as a light source, the power consumption of the halogen lamp and the discharge lamp is much larger than that of the light-emitting diode relative to the light-emitting diode, so the conventional lighting device cannot satisfy the present day. The need for power saving.
