Description

The present invention relates to a lighting apparatus that is installed not only in the interior of furniture, Buddhist altars, and the like, but also in indoor stairs, toilets, and corridors that are inconvenient for the elderly and physically disabled.
[Background technology]

Conventionally, as a light source used for the intended purpose of the present invention, there are many 100V, 30W mini-reflective bulbs and 100V, 15W or 20W jujube bulbs. In addition, 12V, 10W xenon bulbs and 12V, 20W mini-halogen bulbs that require a transformer to transform the power supply 100V to 12V were used. Is a point light source. Since the light is partially strong and the whole is not bright and soft, but generates heat, it is impossible for safety reasons to attach a lens for focusing or diffusing the light on the front, and power consumption is also large. It was.
[Disclosure of device]
[Problems that the device tries to solve]

  All conventional lights of this type have a large size, a single light source, a light source and strong shadows, making it difficult to see the dark side of the product. There is a danger of overheating due to heat generation due to consumption, and it is difficult to attach a lens or the like on the front surface. Moreover, the lifetime of the light bulb was short and uneconomical.

In recent years, this type of light has low power consumption, uses a safe LED unit that does not generate heat, is equipped with a large number of chip LEDs, diffuses and softens light, brightens the whole, and eliminates shadows Lights are becoming popular, and a large number of single chip LEDs are assembled into a surface light source, and in order to focus and diffuse the light, a light with a lens attached to the front surface has been developed in the same way as a light source using a light bulb. ing. Also, an LED unit in which a large number of chip LEDs are arranged in a line in a line has been developed. However, it has more utility as a sign than as an illumination. Therefore, a single chip LED has a bare light bulb structure, When focusing and diffusing actions are required, lenses are individually mounted on a single chip LED.
[Means for solving problems]

The LED light according to the present invention is an energy-saving type that consumes little power and does not generate heat, and uses a large number of long-lived chip LEDs arranged in series without a longitudinally upward U-shaped base case, and the light source is a linear ray. This is a long illuminating device with a rod that is made of a transparent resin material on the front side, and it can focus, diffuse or disperse light according to the purpose of use and installation location. Light.
[Effect of device]

  The effects of the present invention configured as described above are as follows. The light of a plurality of chip LEDs, which are composed of a chip LED and an LED substrate and arranged in series, is focused, diffused or dispersed according to use by the lens action of a transparent resin rod. . If the transparent resin rod has a circular cross-sectional shape, the light is focused and the light intensity is doubled. When light from a large number of chip LEDs arranged in series passes through a single transparent resin rod, such as when the light is dispersed, the effect of focusing, diffusing and spectrally separating long continuous light can be exhibited.

  The chip LED 2 is safe because it does not break like a light bulb using a metal heating wire and has a long life, so maintenance is unnecessary, the light source spreads linearly, and heat generation is extremely small. , Energy consumption can be achieved with low power consumption. In addition, since the LED unit composed of the chip LED 2 and the LED substrate 3 is arranged in series on the longitudinal base case 1, the number and size of the light source to be connected are selected according to the application, and the length and luminous intensity of the light source are determined. It can be set as appropriate. Furthermore, since the whole is formed in a slim shape, there is an advantage that it is easier to use than a cold cathode tube. [Best Mode for Carrying Out the Invention]

In the present invention, as shown in the accompanying drawings, an arbitrary number of LED units each composed of a plurality of chip LEDs 2 and LED substrates 3 are mounted in series on the bottom of a table case 1 having a U-shaped longitudinal section upward. This configuration can also use a commercially available LED module. The transparent resin rod 4 formed in a shape having a curved line or a straight line such as a circular shape, a semi-circular shape, a convex lens shape, a triangular shape, a trapezoidal shape, etc. is disposed on the upper side of the serial LED unit, and the base case 1 and the end cover 5 are fitted to both ends of the transparent resin rod body 4.
[Example 1]

  Embodiments will be described below with reference to FIGS. 1 and 2 of the accompanying drawings. Reference numeral 1 denotes a longitudinal base case 1 whose cross section is formed in an upward U-shape, and an arbitrary number of LED units composed of a plurality of chip LEDs 2 and LED substrates 3 are continuously arranged in series at the bottom. The cord 8 is connected to a household power source AC, 100V via an adapter 9 having an insertion piece 10. The adapter 9 is a commonly used input, AC 100 to 120 V, 50/60 Hz, 0.3 A. An adapter with output, DC9V, 1.2A standard can be used. The number of chip LEDs 2 mounted on the LED unit and the number of LED units to be connected are set as appropriate in accordance with the purpose of use and installation location.

  On the upper side of the LED unit, a transparent resin rod body 4 is arranged along the entire length of the LED unit so that light of all the chip LEDs 2 passes, and the base case 1 and the transparent resin rod body 4 End covers 5 provided with attachment portions 6 are fitted to both ends, and fixed with attachment screws 7. Since the transparent resin rod 4 is made of a resin material, it is lightweight and easy to mold. By using an acrylic resin, light transmission efficiency is good and transparency coloring is also easy.

  The transparent resin rod body 4 has a cross-sectional shape that is formed by a curved line such as a circular shape, a semi-circular shape, a convex lens shape, etc. in order to focus, diffuse, and divide light according to the purpose of use and installation location. The shape can be a straight line such as a triangle or trapezoid. 3 shows a case where the cross-sectional shape of the transparent resin rod is formed in a circle, FIG. 4 shows a case where the cross-sectional shape is a semicircle, FIG. 5 shows a case where the cross-sectional shape is a triangle, and FIG. A case where the trapezoid is arranged in the reverse direction is shown.
