Description

Reflective lighting device

The present invention relates to a light-emitting device, and particularly to a reflective light-emitting device.

General light-emitting elements, such as light-emitting diodes, are point light sources. For the development of surface light-emitting sources, the more high-brightness light-emitting elements, the higher the luminous intensity at the center, making it more difficult to achieve uniformity of the surface light source, even through fluorescent light. The light conversion of the light-powder layer, or the adjustment through the secondary optics, when viewed from the outside of the light-emitting device, the light emitted from the light-emitting element is the light color of the central portion stronger than the surrounding. Therefore, in the case where a light-emitting element is used in combination to uniformly emit light, in general, a light guide plate is used as a medium for uniformly emitting light. However, the larger the light-emitting area, the greater the brightness deviation. Large-scale advertising information boards such as Kanban are projected as light sources by arranging multiple point light sources.

In addition, the light source used in the conventional advertisement information signboard is a halogen lamp or a discharge lamp. For example, as shown in FIG. 1, a light emitting device 101 is arranged obliquely below the front of a signboard 100, and the signboard is illuminated with light emitted by the light emitting device 101. The illuminated surface (surface) 102 of 100 is an external illumination type 103. The light-emitting device 101 used in the external-illumination type lighting device 103 is a light-emitting device 101 that reflects the irradiated light from the light source 104 by a reflecting member 106 installed inside the housing 105 and refracts the light emitted from the light source 104 by a lens 107. The emitted light and the reflected light that has arrived after being reflected by the reflecting member 106 are emitted, and the lens 107 is used to irradiate the emitted light from the light source 104 and the reflected light from the reflecting member 106 to the illuminated surface 102. This applies to advertising information, including information about elections, housing, or cultural events.

However, for the existing lighting device, the structure of the light-emitting device is complicated and the number of parts is large, so that the price of the product equipped with the light-emitting device has been repeatedly increased due to the price of the material, and at the same time, it cannot structurally meet the need to save space. In addition, since the conventional lighting device uses a halogen lamp or a discharge lamp as a light source, compared to the light emitting diode, the power consumption of the halogen lamp and the discharge lamp is much larger than that of the light emitting diode, so the traditional lighting device cannot meet the current requirements. Power saving needs.
