New Description: [New Technology Field] This creation department is about a lighting device that uses LED as a light source. The main light source converts a point light source into a strip-shaped surface light source, which can be used as a lighting device. [Prior Art] Most of the lighting devices currently seen are neon tubes and bulbs. Among them, the lamps are mostly long light sources and % light sources. The bulb is mostly a spherical light source, or a type of spiral light source that is rolled by a thinner tube. LED (Light Emitting Diode) has the advantages of power saving, high luminous efficiency, small size, etc., and is now used as a display light in circuits. Today's LED production technology is extremely mature, and its brightness has reached the level of lighting. Therefore, the industry has used L]ED on the projection lamp. When LEDs are to be applied to lighting equipment, it is necessary to assemble several LEDs into one lighting device to generate sufficient brightness to replace the traditional lighting fixtures. However, (4) is the point of the volume #to, and more than two points are projected onto the object to produce a complex image, causing a visual deviation. Therefore, how to effectively consider lighting equipment is an issue that the industry is keen to solve. [New content] The main purpose of this creation is to provide an illumination device with LED as the light source, which mainly converts the point light source of the LED into a surface light source to provide a relatively uniform projection light and improve the illumination effect. 5 M345956 The "LED-based lighting device" provided by this creation can eliminate the phenomenon of multi-image caused by multiple point sources. The "LED-based lighting device" provided by the present invention comprises: a circuit board, a long curved transparent plate, and a lamp holder device. The curved transparent plate is disposed under the circuit board such that light emitted by the LEDs on the circuit board is transmitted through the transparent plate. The circuit board is provided with at least two LEDs arranged in a row. The outer side of the curved transparent plate has densely arranged curved ridges. The light emitted by the LEDs passes through the collecting action of the arc strips on the transparent plate, and the light is distributed at each of the solitary ridges to form a plurality of wires, which are caused by the tightly twisted wires. The job board is formed as a single light source as a whole. The "LED-based lighting device" provided by the present invention, wherein the length and width of the curved transparent plate are affixed to the wealth (4) of the electric power. The curved ridge on the curved transparent plate is a convex lens and has a collecting effect. The "ED is a light__device" provided by the solution, and the lamp holder device is mainly assembled and fixed for the circuit board and the curved transparent plate. [Embodiment] When light of two or more LEDs is projected onto an object, a ghosting phenomenon occurs, so that the effect of the LED on the device cannot be accepted. The person in charge is researching and creating the creation of the fairy, so that the (10) point light source on the second _ can be converted into a face money to eliminate the problem of copying. _ 实实_, and with _, detailing the technical characteristics of this _ 6 M345956 Please refer to Figure 1 to Figure 4, this creation reveals a lighting device with LED as the light source 'which contains · a circuit board 20, a long A strip-shaped curved transparent plate 3〇 and a lamp holder device 1〇. The curved transparent plate 30 is disposed under the circuit board 20 such that the light emitted by the LEDs 21 on the circuit board 20 must pass through the curved transparent plate 3 and be ejected. The circuit board 20 is provided with a column! ^!) 21, the number of LEDs 21 is at least two. In the present embodiment, the number of the LEDs 21 is nine. The light of the illuminating device is projected downward, so that the LEDs 21 are disposed on the lower end surface of the circuit board 2 。. The curved transparent plate 30 has a length and width sufficient to shield all of the LEDs on the circuit board 20. The outer side of the curved transmissive 3 () has a plurality of arcuate ribs 31 which are parallel to each other and densely arranged. The curved ridges 31 form a plano-convex lens having a collecting effect. Qing, the three-dimensional distribution of the miscellaneous bribery is provided with a number of concentrating lenses. The arc of the curved flap 3G is selected such that the arc of the curved portion of the LED 21 is the vertical direction of each of the curved ridges 31 on the moon-shaped plate 30 and is perpendicular to the direction of the 21 Interlaced state. The wire assembly 10 is mainly used in the tilting circuit board 2G and the ___ assembly to form a structure of the complete lighting device. The lamp holder device H) is internally provided with an electric system (10) (4), and the circuit money mainly provides a front electric miscellaneous feeding path. The circuit system is of conventional knowledge and is not a technical feature of the present invention, and therefore will not be described. The light projected downward by L (four) on the plate 2G passes through the condensing action of the curved ridges 3i on the curved transparent Γ ^ curved transparent plate 3G, so that the fish _ strip _ into - Line Langfa 7 M345956 P - The light projected by each LED 21 on the circuit board 20 passes through the curved transparent board, which enables the light to be distributed throughout the curved transparent plate 3, making 30 become A surface light source. In this embodiment, the curved protrusions of the transparent plate 30 extend in a front and rear direction. The column (10) 2 provided on the circuit board 2G is arranged in the left and right directions. Therefore, the extending direction of each of the curved ribs 31 is perpendicular to the direction of the (4) 21 _ column. In this way, a large number of curved ridges 3 can be disposed on the ship-shaped day-wearing 3() wire to distribute the light more evenly on the curved transparent plate. Each of the LEDs 21 on the circuit board 20 is a __ column. The setting position of the Na-shaped transparent plate 3〇 must make the entire _ flap 3 () face Μ projection of the projected light. If the distance between the curved transparent plate 30 and the circuit board 2G is too small, the position of the arc-shaped transparent plate 3 is not exposed to light, and the dark transparent plate 30 causes dark blocks, which cannot be Form the whole system. Actually, the distance between the f-plate 20 and the curved transparent plate 30 is equal to or slightly larger than the adjacent two (10)? ! The spacing is preferred. In the above-mentioned 16 cases, the LEDs 21 of the shaft are point light sources, but through the arrangement of the curved transparent plates 3', the light emitted by the curved transparent plate 3G is used as the entire surface light source, so that the objects under the lamp can be eliminated. Photocopying phenomenon. The inner side surface of the arc-shaped transparent plate 30 can be made into a fog-like surface, so that the light of (4) 产生 is diffused after entering the curved transparent plate 3G, so that the light is distributed in the curved transparent plate 30. To be even. Then, through the concentrating action of the curved ridges 31, the light which is more transmitted is more uniform. The “LED-based light source” provided by this creation has a curved transparent plate with a number of M345956 dense curved ridges, which converts two or more LED point light sources into a surface light source, eliminating the problem of copying. In addition to being used on long strips, this unit can also be used on the ceiling to replace traditional long strip lighting.
