Definitions

  • the present invention relates to a self-ballasted fluorescent lamp having a synthetic-resin globe, and an illumination apparatus using the self-ballasted fluorescent lamp.
  • this type of self-ballasted fluorescent lamp is miniaturized to dimensions close to a general illumination lightbulb, which is defined in Japanese Industrial Standards, and has an approximate appearance to a general illumination light bulb. More specifically, there has been known a self-ballasted fluorescent lamp, provided with a lamp base which can be fitted to a socket for a general illumination light bulb such as an incandescent light bulb, with a light-emitting tube bent into a compact shape so that it can be enclosed in an ultraviolet-absorbable synthetic-resin globe (for example, see Patent Document 1).
  • a self-ballasted fluorescent lamp including a light-emitting tube which is arranged in a limited space inside a globe and has an increased a discharge-path length by forming it into a spiral, has been proposed (for example, see Patent Document 2).
  • This self-ballasted fluorescent lamp has a globe divided into two pieces which are joined so as to resemble a general illumination light bulb whilst still being able to enclose the relatively large spiral of light-emitting tube bulb in the globe.
  • the self-ballasted fluorescent lamp which has a bulb of a light-emitting tube increased a discharge-path length by forming the bulb in a spiral, the distance between the light-emitting tube and the interior of the globe becomes close.
  • the globe is easily deteriorated by receiving ultraviolet light radiated from the light-emitting tube, and the color of the globe turns to a yellowish color, and a decrease in the amount of light transmitted through the globe over time becomes a problem even when an ultraviolet-absorbable synthetic-resin globe is adopted.
  • it has been an important point on how to improve this problem in a self-ballasted fluorescent lamp having this type of synthetic-resin globe.
  • the present invention has been made in view of such a problem, and an object thereof is to provide a self-ballasted fluorescent lamp, which can prevent deterioration of a synthetic-resin globe and a lowering in appearance of a globe, and an illumination apparatus using the self-ballasted fluorescent lamp.
  • a self-ballasted fluorescent lamp comprising a lamp base (1, 2) carrying a fluorescent tube (4) bent into a compact shape and a translucent outer globe (6) enclosing the tube, the globe comprising a synthetic resin including an ultraviolet absorber, characterized in that the inner wall surface of the tube is coated with an ultraviolet absorbing film (4n) and a phosphor layer (4m) is formed on the ultraviolet film.
  • a further aspect of the invention provides self-ballasted fluorescent lamp comprising a base including a cover having a ferrule at one end of the cover; a light-emitting tube arranged at the other end of the cover, having a pair of electrodes, and having a bulb with an ultraviolet absorbing film formed between an inner wall surface and a phosphor layer formed on the inner wall surface; a globe attached at the cover at one end of the globe, housing the light-emitting tube, and formed with synthetic resin which is added to an ultraviolet absorber and has translucency; and a lighting device housed in the cover.
  • Translucent synthetic resins for example, polycarbonate, acrylic, polyethylene terephthalate, and polyethylene resins are acceptable for globe use.
  • the globe may be transparent and colorless, or implemented with a unit such as a coloring or diffusion unit depending on the required properties.
  • a reflection unit such as a reflective film may be formed to a part of the globe etc., to improve a light distribution property.
  • Shapes of the globe are similar shapes being the same or substantially the same shapes as, for example, A-type, S-type, and PS-type normally called a teardrop shape and a G-type globular shape which have the same appearance and shape as a bulb of a general illumination light bulb such as an incandescent light bulb.
  • a translucent synthetic resin composing the globe is preferably an ultraviolet-absorbable resin per se, for example, a copolymer containing a first monomer M consisting of carbonate esters and a second monomer M' having ultraviolet absorbing function, and may also be a polycarbonate ester (polycarbonate) resin added to an ultraviolet absorber.
  • the resin may contain benzoate, cinnate, benzotriazole, or oxanilide compounds as an ultraviolet absorber.
  • the light-emitting tube may be a spiral light-emitting tube formed by bending a single straight tube member in a spiral or, for example, a bent-shaped light-emitting tube which has a single discharge path formed by juxtaposing three U-shaped tube bodies, and the form of the light-emitting tube is not limited to any specific one.
  • the ultraviolet absorbing film may include, for example, titanium oxide (TiO 2 ), zinc oxide (ZnO), cerium oxide (CeO 2 ), or ferric oxide (Fe 2 O 3 ) microparticles.
  • the globe has a wall thickness from 0.5mm to 1.5mm, and is formed with a thermoplastic resin with total ray transmittance of 85% or higher in a visible light region and linear transmittance of 10% or lower.
  • the wall thickness of the globe When the wall thickness of the globe is less than 0.5mm, as a predetermined wall thickness is required from the viewpoint of maintenance of welding intensity, etc., to weld the divided and joined surfaces of the globe such a wall thickness does not satisfy the predetermined one. In addition, an increase in the linear transmittance results. When the wall thickness of the globe is over 1.5mm, the wall thickness affects the total ray transmittance, and thus, a luminous efficiency is decreased as a result. Moreover, the ranges of the wall thickness, the total ray transmittance, and the linear transmittance in the globe affect a wall thickness required for welding of the globe, and thus the wall thickness affects the total ray transmittance and the linear transmittance. Therefore, it is preferable that the globe has a wall thickness from 0.5mm to 1.5mm, a total ray transmittance in the visible light region of 85% or higher, and a linear transmittance of 10% or lower.
  • the globe has the greatest diameter part on a top side, which is the other end side of the globe, and a decreased diameter part at a one end side attached at the cover, and the globe is divided into at least two parts, divided and joined surfaces are attached by welding; and the light-emitting tube has a swelling part with a larger diameter on a top side, which is the other end side rather than one end side in at least a part with the light-emitting tube and has a part with a diameter larger than that of the decreased diameter of the globe.
  • the globe is divided along a direction substantially perpendicular to a lamp axis line at the greatest diameter part of the globe in a transverse direction so that a decreased diameter part side and top side of the globe are divided.
  • the globe may be divided at the decreased diameter part side or the top side located adjacent to the greatest diameter part, or may be divided in an oblique direction without bisecting at right angles to the lamp axis line.
  • the globe may be divided along the lamp axis line in a longitudinal direction. In other words, all units that enable to insert the greatest diameter part of the light-emitting tube into the globe are acceptable.
  • the parts of the globe are attached by ultrasonic welding.
  • both of the divided and joined surfaces are fused and welded instantaneously by frictional heat generated by application of an ultrasonic vibration with one divided and joined surface of the globe and the other divided and joined surface of the globe opposing each other.
