Description

  The present invention relates to a fluorescent lamp type illuminating lamp using an LED (light emitting diode) that can be used as it is in an existing fluorescent lamp fixture and can illuminate over a wide-angle wide range.

  Conventionally, as a light emitting element mounting structure of a light emitting module for an optical communication system, a light emitting element attached to a spacer having an inclined surface inclined in the outer peripheral direction on a circular substrate is disclosed in Japanese Utility Model Publication No. 63-106246 (Patent Document 1). However, in a fluorescent lamp type illumination lamp, an illumination technique in which the spacer is provided on a substrate on which a large number of LEDs are electrically arranged has not been proposed. Further, from Patent Document 1, the technical idea of illuminating the light axes of the light emitting elements in opposite directions cannot be conceived.

  Accordingly, the present invention provides a fluorescent lamp type LED lighting lamp in which each LED arranged in a plurality of rows in the longitudinal direction of the support substrate can illuminate the left and right sides of the longitudinal direction over a wide angle over a wide range. Is to provide.

A fluorescent lamp type LED illumination lamp according to claim 1 of the present invention includes a transparent or semi-transparent cylindrical tube and a pair of electrode terminals connected to both ends of the cylindrical tube and respectively fitted to a socket portion of a fluorescent lamp fixture. With a bottomed cylindrical base cap projecting horizontally in the longitudinal direction, a support substrate built in the cylindrical tube, and a plurality of pieces arranged in a plurality of rows along the longitudinal direction of the support substrate In a fluorescent lamp type LED illumination lamp consisting of an LED group consisting of LEDs and an electric circuit disposed between the LED group and the electrode terminal,
In both outer rows along the longitudinal direction of the support substrate, a large number of spacers each having an attachment surface having a required gradient are arranged outward, and the LED has its optical axis facing outward on the attachment surface of each spacer. Each LED is connected to the electric circuit.
The invention described in claim 2 is the fluorescent lamp type LED illumination lamp described in claim 1,
The spacers arranged in the outer rows are arranged in a staggered manner from each other.

  As described above, according to the fluorescent lamp type LED illuminating lamp of the present invention, it is possible to illuminate a wide range over a wide angle even with the use of a single-lamp type fluorescent lamp apparatus, which is extremely useful for illumination in straw cultivation with a low illumination space. Moreover, in the arrangement of the LED groups on both sides, those in which the LEDs are arranged in a staggered manner exhibit an energy-saving lighting effect. Furthermore, in the present invention, since LEDs arranged in the same phase and LEDs arranged in a staggered manner can be mixed, the illumination of the LED such as illumination by one of the LED groups or illumination by both of them can be mixed. It also exhibits an effect that the illuminance can be easily changed by switching the illumination circuit.

Explanatory drawing of the arrangement | sequence in which each LED chip 5a of the LED group 5 arranged in 3 rows on the support substrate 4 is arranged in a series of V shape, and each LED chip 5a of a center row lights left and right alternately. Explanatory drawing of the arrangement | sequence which each LED chip 5a of the LED group 5 arranged in 2 rows on the support substrate 4 illuminates an outer direction, respectively by the same phase.

  Since the arrangement form of the spacers in the present invention is arranged corresponding to the plurality of rows of LED groups on the support substrate, the arrangement form in the same phase on the left and the right, the arrangement in the zigzag form on the left and right, etc. It is. In addition, the arrangement in the intermediate portion includes an LED in which the optical axis of the LED is vertical, an arrangement in which the optical axes are alternately changed in the left and right directions, and an arrangement in which both are mixed.

The present invention will be described with reference to an embodiment. As shown in FIG. 1, a fluorescent lamp type LED illuminating lamp A of the present invention is joined to a transparent or translucent cylindrical tube 1 and both ends of the cylindrical tube 1, respectively. A bottomed cylindrical base cap 3 in which a pair of electrode terminals 2 that fit into a socket portion (not shown) of a lamp fixture are projected horizontally in the longitudinal direction, and a support substrate 4 built in the cylindrical tube 1. The LED group 5 composed of LED chips 5a as a plurality of LEDs arranged in a plurality of rows along the longitudinal direction of the support substrate 4, and the LED group 5 and the electrode terminal 2 are electrically connected As shown in FIG. 2, each LED chip 5 a is required with respect to the horizontal plane of the support substrate 4 in both outer rows (left and right rows) along the longitudinal direction of the support substrate 4. Joined with an attachment surface 7a having a gradient (15 °) Attached to said mounting attachment surface 7a of the pacer 7, formed by connecting the LED chip printed circuit board of the electric circuit 6 which the anode and cathode terminals are joined to the back surface of the supporting substrate 4 5a penetrating the spacer 7.
The LED groups 5 composed of a large number of the LED chips 5a are arranged in two rows along the longitudinal direction of the support substrate 4, and each LED group 5 is arranged in the base cap 3 as shown in FIG. The pair of electrode terminals 2 of the base 3a joined to the base cap 3 and the pair of electrode terminals 2 disposed on the base 3a of the other base cap 3 are electrically connected via the diode bridge 6a. Here, the spacer 7 that joins the LED chips 5a will be described. This is a state in which the optical axis of the LED chip 5a is expressed when the illumination is used in a state where the LED chip 5a is attached to the support substrate 4 and is required in the vertical direction. Since the spacer 7 shown in FIG. 2 has only to have an attachment surface 7a that is directed outward at an angle (15 °), the spacer 7 shown in FIG. The side is the attachment surface 7a of the LED chip 5a. Instead, as shown in FIG. 4, the acute apex of the right triangle is cut and the hypotenuse is used as the attachment surface 7a of the LED chip 5a. Also provided by things.

Next, the form of the arrangement of the LED groups 5 will be described. In FIG. 5, the LED chips 5a arranged in the LED groups 5 on both sides of the support substrate 4 have their arrangement phases mutually changed. Are arranged in a zigzag pattern and are illuminated with optical axes directed to the sides at the required angles as indicated by arrows, respectively, and the one shown in FIG. 6 is arranged in three rows on the support substrate 4 The LED chips 5a arranged in the LED groups 5 on both sides of the LED groups 5 are arranged in a staggered manner, and the LED chips 5a of the LED groups 5 arranged in the center are also described above. The direction of the optical axis is alternated at a required angle in the left-right direction so that the LED chip 5a on both sides is positioned in the middle of the arrangement pitch, that is, the three members form a series of V-shapes. These are arranged and distributed.
Further, in the case shown in FIG. 7, the LED chips 5a of the LED groups 5 arranged in two rows are laterally at the required angle via spacers (not shown) as indicated by arrows in the same left and right phase. Illuminates with the optical axis directed.

  Since the fluorescent lamp type LED lighting lamp A thus configured can illuminate over a wide-angle range, it is suitable for lighting in straw cultivation with a low shelf interval.

  Since the present invention can illuminate a wide range of lighting with low lighting space for each shelf, the demand is highly expected as a suitable for vine growers, and the activation of the lighting equipment industry It also helps.
