Description of the Invention (Field of the Invention The present invention relates to light bulbs, and more particularly to light emitting diode (Light Emitting Diode, hereinafter referred to as LED) bulbs for lighting traffic signs. Invention Background 5 Most traffic lights are illuminated by incandescent bulbs that are screwed into standard rotating lock-type light sockets. 9 The bulbs have color and / or shade lenses above them to indicate when drivers and pedestrians can enter intersections. The shielding lens forms a symbol such as an arrow, a hand, a person, a letter, or a text by blocking light from passing through selected portions of the lens. 10 Conventional lighting traffic signs have some disadvantages. Used here Standard incandescent light bulbs have a fairly short life span. Furthermore, this bulb consumes a lot of energy. I am particularly concerned about this issue because most traffic signs are constantly operated. Another disadvantage of the known traffic signs is that they are used to generate The masking lens that illuminates the symbol image wastes energy; because it blocks the light 15 produced by the bulb to form the image. So comes from the lamp A large amount of light wasted is used as the heat absorbed by the lens, instead of the light projected by the traffic sign. I need a traffic sign bulb that has a longer life and uses less energy than the conventional traffic sign bulb. . Furthermore, 'I need this bulb that forms the required symbolic image of the light without the use of a shielded lens that is expensive and wastes energy. Finally, I need this one that is compatible with standard rotary lock-in bulb sockets. Bulbs, so existing traffic signs can be trimmed with new bulbs. SUMMARY OF THE INVENTION The present invention provides a trimmed lamp by providing a light-emitting diode with a locking turntable.

Description of the invention () {Please read the notes on the back first / fill in (Buy)) to solve the aforementioned problems, and have a longer life and use less energy than conventional bulbs, and screw-lock standard screw-lock bulb sockets to provide the Proper rotation of the bulb. Furthermore, the shape of the LED trimming bulb can be designed to form a lighting symbol that can be used alone, or used with existing or new shielding type 5 lenses for improved contrast. The light-emitting diode trimming bulb installed in a screw-type screw-locked electric socket of a traffic sign includes a socket shell, a printed circuit board, and most light-emitting diodes. The socket housing has a lower end that terminates in a threaded base for insertion of a threaded rotary lock-in electrical socket. The printed circuit board is rotatably mounted to the socket housing. The plurality of light emitting diodes are mounted to the printed circuit such that the plurality of light emitting diodes form a symbol image. The printed circuit board can be rotated relative to the socket housing, and can not rotate the symbol image formed by the light emitting diode to a desired rotation position relative to one of the socket housing. 15 In another aspect of the present invention, an LED light bulb installed in a screw-type electrical socket of the Central Bureau of Standards of the Ministry of Economic Affairs of the Ministry of Economic Affairs's Consumer Cooperatives includes a socket housing, a printed circuit board, and most light-emitting diodes. diode. The socket housing has a lower end that terminates in a threaded base for insertion of a threaded rotary lock-in electrical socket. The printed circuit board is rotatably mounted to the socket housing. The plurality of light emitting diodes 20 are mounted to the printed circuit in such a manner that at least some of the diodes are guided to the printed circuit board at an oblique angle.

Description of the invention () " Locking turntable 12 includes a threaded base ι8, a hollow socket housing 22, a circuit housing 26, a retaining ring 30, a spring 34 and an electric wire 3 ^ The threaded base includes external threads 20 p engaged with a standard screw-locked light bulb socket. The hollow socket housing 22 has the threaded base 18 5 at its lower end and internal threads 24 at its upper end. The circuit housing 26 has an upper portion 27 that houses a circuit system 28 for operating the LED 16, and a lower portion 29 that rotatably engages a retainer 30. The circuitry 28 used to operate the LEDs via rectification and / or reduction of the incoming line voltage is an industry standard device and will not be discussed further herein. The retainer 30 has a male screw thread 32 and a female screw thread 24 that engage the female screw thread 24 of the socket housing 22. Once the external thread 32 of the retainer 30 has fully engaged the internal thread 24 of the socket housing 22, the circuit housing 26 can rotate relative to the socket housing 22 via the lower portion 29 and the retainer 30. The spring 34 is biased against the lower portion 29 of the socket housing 22 and the circuit housing 26. The friction caused by the spring bias between the lower portion 29 and the retainer 30 limits the rotation between the two, for selective selectivity as described below. 15GND Position the circuit housing 26. An electric wire 36 electrically connects the circuit system 28 to the screw-type base 18. It should be noted that another way to replace the use of threads to secure the retainer to the socket housing 22 is, for example, screwing. Printed by the Consumers' Cooperative of the Ministry of Economic Affairs, China Standards Bureau. Once the threaded base 18 fully engages the rotary lock bulb socket of the traffic sign, the lock swivel 12 allows the circuit housing 26 (and therefore the 20 printing The circuit board 14) rotates. This rotation is necessary 'so that after the bulb 2 is installed in the traffic sign socket, the orientation of the arrow formed by the led 16 is set in an appropriate direction. After the base 18 is fully screwed into a traffic socket, the circuit housing 26 is rotated relative to the socket housing 22 via the lower portion 29 and the retainer 30. Once the appropriate orientation of the printed circuit board 14 is reached, the spring 34 applies the Chinese National Standard (CNS) A4 specification (210X v. Mm) at the lower paper size 6814 1 V. Description of the invention () Provided between the part 29 and the retainer 30 Sufficient friction prevents further rotation between the two, which can keep the printed circuit board 14 properly aligned. The LEDs 16 provide brighter lighting with less energy than conventional light bulbs. Most of the light emitted by an LED is roughly projected in the direction that the exit end of the LED wheel 5 points (faces). Therefore, the LED light bulb 2 guides most of its light to the direction of improving the illuminance for the intentional observer, and reduces the amount of light wasted pointing away from the area of interest (such as adjacent traffic lanes, etc.). To the minimum "Furthermore, since the LEDs are arranged in an arrow shape, the use of a shielded lens will provide superior contrast. Another option is that it may use arrow-shaped LEDs with unshielded lenses. Printed by the Central Standards Bureau, Shelley Consumer Cooperative, although the shape of the printed circuit board η in Figures 1A-C is similar to the shape of an illuminated symbol image (an arrow) produced by Led 16, the printed circuit board 14 may have Any shape, as long as the LEDs 16 are arranged to form a desired symbol image. For example, Figures 242B and 2C illustrate a rectangular printed circuit board 14, 15 so that the LEDs 16 are arranged to form a walking pedestrian (Figure 2A), a hand (Figure 2B), or a standing pedestrian (Figure 2C). image. An outline 38 of one of the desired images is formed on the printed circuit board 14, and the LEDs 16 are mounted to fill the drawn image. The LED 16 arrangement prevents most of the opaque mask lenses from radiating, thus maximizing its efficiency. 20 One problem with the rectangular printed circuit board 14 shown in Figures 2A-C is that the printed circuit board 14 cannot rotate inside a typical rectangular pedestrian pedestrian case, which is only slightly larger than the rectangular printed circuit board 14 ^ FIG. 3 illustrates a modified example of the lock turntable 12 so that it can be ideally installed in a rotary lock socket without rotating the printed circuit board.

A wire 42 with a removable electrical connection device 44 connects the LED to the circuit system 28 °. Once the threaded base 18 is fully engaged in the traffic sign socket, the circuit housing 26 is opposite the socket housing 22 Turning to its proper position, the rear whale wire 42 is connected to the electrical connector 44 and the printed circuit board 14 is attached to the circuit case 26 with screws 40 '. A ring-shaped shaft seal 46 between the circuit case 26 and the printed circuit board 14 prevents moisture from entering the circuit case 26. The LED 16 itself may have different colors and / or a color filter placed thereon. It should be apparent from the above description that the trimmed bulb 10 of the present invention can also be ideally used for a traffic sign made recently. Figure 4 illustrates another way to removably mount the printed circuit board 14 to the housing 26 so that the printed circuit board 14 does not have to be rotated when the threaded base 18 is screwed into the electrical socket of the traffic sign. A plug 50 electrically connected to the LED 16 is added. The socket 52 is formed in the circuit case 26 and is electrically connected to the circuit system 15 28. Once the threaded base 18 is fully engaged in the traffic sign socket, printed by the consumer cooperation agreement of the Central Standards Bureau of the Ministry of Economic Affairs and the circuit housing 26 is rotated relative to the socket housing 22, the plug 50 is inserted Socket 52. When the screw 40 secures the printed circuit board 14 to the circuit housing 26, the plug 50 engaging the socket 52 is electrically connected to the LED 16 to the circuit system 28.

Description of the invention () Therefore, the directivity of the output of the bulb is adjusted so that it is guided to the printed circuit board 14 at an oblique angle (not a right angle). For example, the LEDs of all round light bulbs 2 in Figure 5A / B can be led to one side, which is ideal for traffic signs with adjacent traffic lanes that are close together, or for forming a light bulb with the light bulb 2 5 angles of traffic lanes of interest. Another option is to direct some LEDs in one direction and other LEDs in the other direction, and it can be ideally used for light bulbs that direct traffic in more than one traffic lane. It should be understood that the present invention is not limited to the embodiments described above and described herein, but includes any and all variations that fall within the scope of the appended patents. 10 For example, the LED can be used to form an image different from a person, a palm or an arrow.
