Description

[Detailed description of the invention]

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a rod type lighting device used for a mood lamp, a light source for image processing, and general lighting.

[0002]

2. Description of the Related Art In conventional full-color illumination using three primary color LEDs, due to the LED configuration, color unevenness is likely to occur in close proximity, making uniform color illumination difficult.

[0003]

[Problem to be Solved by the Invention] When it is desired to use in close proximity, a method using a milky white translucent diffusion film on the light emitting surface and an LED in which three primary color LEDs are formed in one milky white epoxy resin are used. There was a way to do it.

In these methods, since the light is diffused in advance to reduce the unevenness, the overall illuminance is lower than the original illuminance.

[0005] Further, when the LED lighting is used for illumination when a mirror surface is photographed by a CCD camera for image processing or the like, the individual light emitting elements of the LED are reflected on the mirror surface and taken into the CCD camera.

In order to solve the above-mentioned problems, it is a technical object of the present invention to reduce the decrease in illuminance, eliminate color unevenness, and control light emission of an LED.

[0007]

Means for Solving the Problems In order to achieve the above-mentioned object, the present invention applies or attaches a highly-reflective phosphor to the side surface of a transparent rod, and applies both ends or one end of the rod. Place the board with the three primary color LEDs on it and set it inside the lighting cover.

The three primary color LEDs are connected by a cable from a controller, and the LEDs are controlled by various switches to enable full color illumination.

[0009]

[Function] When the power is turned on, the lamp is lit in the color taught last time, or lights in white if there is no teaching data.

The mode is changed to instantaneous switching, afterglow switching, intermediate color illumination switching, a teaching mode (red), a teaching mode (green) and a teaching mode (blue) by mode selection. The state can be taught.

[0011]

Hereinafter, specific embodiments of the present invention will be described with reference to the drawings. FIG. 1 shows a full-color LED rod-type lighting device according to the present invention. The transparent rod 1 is accommodated in the illumination cover 2 by applying or sticking a phosphor 1a on the side opposite to the light emitting portion.

The illumination cover 2 is connected to an LED board 8 as a light source and the control box 3 by a cable.

FIG. 2 is a side sectional view of a full-color LED rod type illumination device. The functions of various switches of the control box 3 are controlled by a mode selection switch 4 by an instantaneous switching system, afterglow switching system, and intermediate color illumination switching. The mode can be selected from teaching mode (red), teaching mode (green), and teaching mode (blue). The light intensity up switch 5 can increase the light intensity and the light intensity down switch 6 can decrease the light intensity. When it is desired to use the initial value at the next power-on, the teaching switch 7 can save the current light amount state of the three primary color LEDs.

FIG. 3 is a diagram showing the arrangement of LEDs on a three-primary-color LED substrate. An LED substrate 8 having red, green, and blue LEDs individually, and an LED having three primary-color LED chips set in one epoxy resin. These are two examples of the substrate 8 ', and the number of LEDs can be increased or decreased in proportion to the sectional area of the transparent rod.

As shown in FIG. 4, there are three types of lighting methods. As for the instantaneous switching method, red light is turned on, green light is turned on after a certain time elapses, and orange light is turned on. After the time elapses, blue light turns on and turns to light blue.After an arbitrary time elapses, green light turns off and only blue turns on.After an arbitrary time elapses, red light turns on and purple light turns on. The light turns on, and after a certain period of time, the green and blue lights are turned off, and the operation returns to the initial red color, and this operation is repeated.

The overall operation pattern of the afterglow switching method is the same as that of the instantaneous switching method, but the light quantity gradually increases with respect to the lighting of one LED, and after the maximum lighting, the light quantity gradually decreases and finally turns off. .

The overall operation pattern of the intermediate-color illumination switching system is the same as that of the other two systems, and the change in light amount is equivalent to that of the afterglow switching system, but the other two systems are at the moment after one LED is turned on. Turns off and shifts to the next operation.

In this method, one of the LEDs is always lit, and when the other LEDs shift to the light increasing operation or the light decreasing operation, the intermediate color lighting of the resolution unit can be obtained.

[0019]

[Effects of the Invention] As described above, according to the full-color LED rod-type lighting device of the present invention, the LED light is incident from the end of the rod and is reflected and illuminated by the phosphor on the side surface, so that there is no color unevenness. Lighting becomes possible.

Since the emission part is mainly due to the reflected light from the surface of the phosphor, the light emitting element of the LED itself is not visible, so that a uniform surface illumination is possible. The illumination method can be changed in various ways according to various conditions. When used as a light source for image processing, the desired color and light amount can be adjusted, so that the detection target and the background can be easily separated.
