JP3102096U - Full color LED line lamp - Google Patents

Abstract

PROBLEM TO BE SOLVED: To provide an LED in which LED chips of three primary colors of RGB are combined into one package.
The devices are arranged in a line or in a plane to change from a point light source to a full-color line or surface light source.
SOLUTION: A plurality of full-color LED devices each including an RGB three-primary-color LED chip in one package are arranged in series and connected to a metal-based printed wiring board that also functions as a heat radiator to form a linear full-color LED light source. The insufficient light quantity is supplemented by a set of point light sources.

Description

  The present invention relates to an LED line lamp in which a plurality of full-color LED devices are arranged in series.

Generally, incandescent bulbs are being replaced by light bulb-type fluorescent lamps, but LED lamps have longer life and lower power consumption, and they do not use mercury like fluorescent tubes. It can be expected as a next-generation lighting source.

  Since LEDs are point light sources, replacing them with fluorescent lamps requires that they be efficiently assembled and connected, and furthermore, the heat from the LED devices generated by assembling is efficiently dissipated, thereby deteriorating the LEDs. Need to be prevented. In addition, full-color LED devices have been developed for use as an incoming call display of a mobile phone or for nighttime illumination of a built-in camera, but the amount of light alone is insufficient for general illumination.

  The inventor of the present invention has arrived at the present invention as a result of intensive studies in view of this point. The present invention provides a plurality of LED chips of three primary colors of RGB in one package in series, and a metal which also serves as a heat radiator. A line-shaped full-color LED light source is obtained by connecting and arranging on a base printed wiring board.

  As described above, the present invention provides a long-life, low-power illumination by arranging a plurality of LED chips having a shortage of light as general illumination in series, and forming a linear full-color LED light source lamp. It has become widely used as a fixture, such as general lighting, interior lighting, arcade games, and lighting for amusement facilities.

  An LED lamp in which a plurality of full-color LED devices in which one RGB3 chip is contained in one package are arranged in series on a metal-based printed wiring board that also functions as a heat radiator, and are connected. By using a full-color LED light source lamp, it can be used.

  FIG. 1 is a front view showing the surface of a printed circuit board A, and FIG. 2 is a back view of the same. Reference numeral (1) in the figure indicates a full-color LED device, and a plurality (10 in the figure) are arranged in series with the printed circuit board A. Symbol (2) is a connector.

FIG. 2 shows the back surface of the printed circuit board A. (3) in the figure is the printed wiring. What is shown is the actual size actually used.
FIG. 3 is an enlarged sectional view showing the arrangement of the full-color LED device and the connector.

  A plurality of full-color LED devices developed mainly for mobile phones are arranged in series on a printed circuit board and connected to be used as a linear full-color LED light source lamp.
