Creation Instructions (1) ~ -------- [Technical Field to which the New Type belongs] This creation is about a kind of Zhaoming yue ^. # 00 ^ θ #% gel ..., especially a kind of moon light The surface light source is a light fixture with nine bright lights, and it also has a surface torture At Sun Sword 昍 4 S ΙΑ A — team ο surface light ^ ^ Evil light has good lighting efficiency, surface light source:,: ίί =, more power saving and long life Long and not easy to heat, low into ti compared: security, and thin and short easy to carry and other advantages and effects. [Xianli Technology] There are many types of uniform floor lamps (as shown in Figure 10), but most of them still use bulb 9 1 (or tube) as the main light source. —Another type is to directly use a light-emitting diode as a light source, such as the traffic light M of the point light source array not shown in Figs. 11 and 11, and an array of point light sources 9 2 1 is provided thereon. . However, all of the conventional techniques have the following shortcomings: [1] The point light source type has poor lighting efficiency. If the conventional table lamp directly uses a light emitting diode of a relatively large and wattage as the light source, although the cost is low, the point light source state cannot provide sufficient lighting, the brightness is insufficient, and the lighting efficiency is poor. [2] Point light sources are prone to shadows. If a plurality of light-emitting diodes are directly arranged in an array as a light source, even though a brighter light source can be generated, the shadows caused by the simultaneous illumination of a plurality of light-emitting diodes cannot be avoided, and the uneven light emission is all missing. [3] Power consumption, limited elder life, and easy heating. Traditional light bulbs consume large amounts of electricity and the heat generated by them cannot be quickly and efficiently dissipated. After a long period of lighting, the bulb (moss) is easy to burn out, and its life is limited. In addition, there is still a lack of heat. [4] Toward cost and not environmentally friendly. Due to the short life of traditional bulbs or tubes,

In addition, the quality of conventional lamps will pollute the environment, which is a mercury-containing substance that needs to be returned (such as fluorescent tubes) [5]. It is bulky and unfriendly to carry. Xi ^ is not environmentally friendly. It has a certain volume. It is not convenient to carry it because of its large size. 1 Λ is not easy to put in the pocket of clothes or so, how to develop a lighting efficiency ^ belt lighting device is the industry should study ^, dare to carry it with you [new content] Ϊ 黑 占 ° This creative lamp, its furniture This creative lamp has the original creative lamp, it has the original creative lamp, it has the original creative lamp, it is

Also, the dot-shaped light-emitting unit 2 2 can be selected from one of an edge-light type and an upward-type light-emitting type. M277862 Fourth, creation instructions (4) light-emitting diodes. The light-shielding support base 30 is used for supporting and fixing the light-guiding structure 10 and receiving the light-emitting portion 20. Take this bundle of L1, after turning up the 90th, 2nd, and 3rd, of course, if you modify it, add at least the same, see at least the diffuse film, gather about the first carrier 30 series, the second carrier 3 0 series, the third is In the present invention, the covering is thick, and the plurality of dot-shaped light emitted by the plurality of dot-shaped light-emitting units 21 enters the light-guiding structure 10 from the corresponding side surface 13, and is emitted by the light-emitting surface 11 to a large degree. A uniform planar light source L2 (as shown in Figure 4). The reflecting portion 14 may be a reflective optical film or a reflective structure, and the dot-shaped light-emitting units 21 are formed in an L-shaped linear arrangement, and the effect is preferably a single-line arrangement, which can also emit light, but the brightness is poor. Please refer to the fifth figure, and there can be another optical microstructure 15 (such as a micro-pit or micro-bump array) on the light-guiding structure of this creation. Fifth figure, this creation may further include: a layer of an optical film 16 which is selected from one of a focusing film and a focusing diffusion film. The practical application of this creation has at least the following three application modes: The type is "table lamp".
