JPH0571887U - Signboard with a combination of funnel type reflector and light emitting diode - Google Patents

Abstract

(57) [Abstract] [Purpose] A signboard composed of a combination of a funnel-type reflector and a light-emitting diode, which has a structure that shares the effect of the self-luminous light emitted from the light-emitting diode and the retroreflected light emitted from the reflector. [Structure] Of the light emitted from the light emitting diode, the light that travels laterally or obliquely is retroreflected by the funnel-type reflector and appears as reflected light, so that the light emitting portion is seen as enlarged.

Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a signboard represented by a signboard and a signboard.

[0002]

[Prior Art]

 In order to utilize the strong straightness of light of the light emitting diode, the signboard using the light emitting diode is mounted in a device in a cylindrical container or a device in which a certain section is defined. , Characters and figures were displayed. As a signboard using a reflective material, as represented by road signs and road signboards, etc., the light emitted from a car or other object is retroreflected to improve the visual recognition effect and identify the sign.

[0003]

[Problems to be solved by the device]

 The objective is to construct a signboard that can be distinguished both day and night by combining a reflective material that has an effect by reflecting light from another object with a self-luminous light emitting diode. Also, of the light emitted from the light emitting diode, the light diffused laterally or diagonally was effectively used.

[0004]

[Means for solving the problem]

 The present invention does not utilize the effects of self-emission and retroreflection separately but devises a combination that can share the effects. The means will be described with reference to FIG. 3. Since the light (6 ″) emitted from the light emitting diode (2 ″) and the light diffused laterally or diagonally are received and reflected light is emitted, the funnel type reflector is used. The combination of (1 ”).

[0005]

[Action]

 As a result, an area equivalent to the outer circumference of the funnel-type reflector (1), which is wider than the width of the light emitted by the light-emitting diode (2), can have the same effect as self-luminous emission. Of course, if the light emitting diode (2) does not emit light due to insufficient power supply, the funnel type reflector (1) is distinguished by the effect of retroreflecting the light emitted from another object. Was also solved.

【Example】

 FIG. 1 is a plan view of a marking plate which is a combination of a funnel type reflector and a light emitting diode according to the present invention, and FIG. 2 is a sectional view taken along line AA ′ of FIG. FIG. 7 is a structural diagram showing the mounting positions of the light emitting diode and the funnel-type reflector. Explaining with reference to the figure, diffusion emitted from a light emitting diode (2 ') attached to a printed circuit board (4) having wiring that represents any character or figure operated by an electric current from a code (5) for introducing electricity. The reverse conical surface of the funnel type reflector (1 ') is retroreflected by receiving the light which is emitted, and the self-luminous portion (6) and the retroreflected light (7) both emit light as shown in FIG. The structure is such that the light emitting part looks enlarged. Of course, in this case, the transparent plastic resin plate (8) molded as shown in FIG. 4, waterproofing with a film, and the substrate (9) for fixing them are fixed.

[Effect of the device]

 The purpose of the present invention is to construct a signboard that can be identified both day and night by combining a self-luminous light emitting diode and a reflective material that receives the light from other objects and can be retroreflected to produce an effect. Moreover, among the light emitted from the light emitting diode, the light diffused laterally or diagonally is retroreflected by the funnel-type reflector, so that the effect of enlarging the light emitting portion can be obtained. In addition, by making the color of the light emitted from the light emitting diode the same as the color of the reflector, it was possible to make the signboard clearer and easier to identify, for example, when the light was red and the reflector was also red. .
