New description: [New technical field] This case belongs to the field of lighting devices, especially the improved structure of lamps that use the light guide column structure to increase the illumination angle to achieve uniform illumination. [Prior Art] According to the 'Light Emitting Diode (LED) system, when a forward voltage is applied to a light-emitting wafer, a monochromatic discontinuous light is emitted, and if the chemical composition inside the light-emitting chip is changed, The wavelength of light required to illuminate the LED. Especially after the advent of white LEDs, LEDs have begun to be widely used in lighting equipment. 'Because LEDs have many advantages compared to traditional light sources. For example, using a lower voltage (5 V~24 V) can drive and brighten up, so it can achieve energy-saving and power-saving effects; and the LED can be used up to 35 in conjunction with an appropriate cooling system or application environment. 〇~50,000 hours, its service life is much longer than traditional light sources, and it will not produce mercury pollution like traditional light sources. However, since LED is a kind of illumination source with a concentrated light source and a small illumination angle, it must be specially designed to become a lighting fixture with sufficient illumination angle and range. Take the common LED bulbs on the market as an example, please refer to the first! The figure is a schematic diagram of the structure of a general LED bulb. As shown in the figure, the bulb 10 mainly has a lamp holder u having a power receiving portion 111 and a plane portion U 2 respectively on the two end faces, and a 3 M404326 circuit board 12' is disposed on the plane portion 11 2 and The circuit board 12 is electrically connected to the power receiving portion lii. The circuit board 12 is provided with an LED light source 13. Finally, a lamp cover 14 is disposed on the periphery of the planar portion 112 to the circuit board 12 and the LED. The light source 13 is covered therein. Usually, the LED light source 13 is a high-power LED chip, which generates high heat after being driven to emit light. Therefore, the lamp holder 11 is usually made of a heat-conducting material such as a metal, and can be dissipated as quickly as possible. The high heat generated by the Led light source 13 prevents the brightness of the LED light source 13 from being affected by thermal attenuation or shortening its service life. However, after the flat portion 11 2 is disposed by the characteristic of the illumination concentration of the L E D light source 13, the irradiation direction of the LED light source i 3 is directed in the same direction as the planar portion 1丨2. Therefore, the general LED bulb 1 is used when it is used, because the illumination angle of the LED light source 13 is not uniform, and the illumination is not uniform. In particular, the lateral light relief is usually greatly reduced. A problem occurs in that a shadow is generated by the light being blocked by the socket 11. Therefore, the present creator has provided a modified structure of a luminaire capable of achieving uniform illuminance in view of the lack of use of a general LED bulb, which utilizes a light guide column having a different refractive index and an environmental medium, and an LED The light source is disposed in the light guiding column, and one end surface of the light guiding column has a critical surface, so that the light of the lED light source is incident on the light guiding column by the environmental medium, and part of the light is transmitted and reflected, and 4 mW4326 has the effect of uniform illumination when the light is reflected at the critical surface of the light guide column to emit light from the 5 lit LED source into the environmental medium.

In an embodiment, in order to increase the brightness of the light 5 M404326 behind the lamp holder side, a plurality of through holes are formed in the periphery of the lamp holder, so that light emitted from the light guide column to the environmental medium can pass through the through holes. Transmitted to enhance its brightness. According to the fact that the light source emitted by the first light source is incident on the light guide column, the light source emitted by the first light source is incident on the light guide column, and the refractive index is different between the two. Part of the light will be transmitted and reflected in the light guide column, and reflected at the critical surface to the direction corresponding to the lamp holder, and then re-exited in the environmental medium. The improved structure of the lamp can be turned to the front and the side. Even a part of the light is emitted toward the side of the lamp holder to achieve uniform illumination. Another object of the present invention is to provide an improved structure for a uniform illumination device. A plurality of struts are used to guide light to an angle behind a lamp holder side, and the yoke is placed on the flank.

In the example, in order to increase the light shell of the lamp holder side, a plurality of through holes are formed in the periphery of the lamp holder, so that the light exiting surface of the end of the wings of the light guide is emitted to the environmental medium. Light rays can be transmitted through the through holes to enhance their brightness.
