JP2002347512A - Backlit license plate - Google Patents

Abstract

PROBLEM TO BE SOLVED: To provide a backlit license plate which enables an improved visibility and which has a ultra-long-life panel light by allowing all characters on an identification plate of the rear part of an automobile running at night to be clearly recognized. SOLUTION: The backlit license plate is a backlit device using a cold-cathode tube with a trigger.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention realizes an improved visibility and a longer life by using a cold-cathode tube with a trigger attached to a trigger that can clearly recognize a character-type license plate of an automobile even at night. can do.

[Prior art]

[0002] A conventional incandescent license plate has two bulbs.
Although it is used for individual lighting, the bulb is relatively vulnerable to vibration and shock.
There was a problem that numbers were difficult to read. The brightness of a conventional cold-cathode tube has decreased at low temperatures.

[Problem to be solved]

[0003] 1. Due to the broken bulb of the light license plate

[0002] The above problem is solved by a long-life cold-cathode tube with a trigger. 2. The cold-cathode tube with a trigger does not lower the brightness even at low temperatures.

[0004]

In order to solve the above-mentioned problems, the present invention has the following structure. 1. Take the power of the number light into the box for the license plate and connect it to the temporary side of the inverter. Connect the electrode part of the cold cathode tube to the secondary side of the inverter. 2. A characteristic feature is that irregular reflection of light is prevented and light is reflected more efficiently by sticking to the side surface of the cold-cathode tube using 1/2 to 1/3 of a metal such as aluminum as a trigger. 3. Another characteristic is that the discharge start is accelerated by attaching the trigger to the cold cathode tube. 4. If the cold-cathode tube is not turned on due to damage, etc., it is detected and a warning lamp is provided.

[0005]

According to the present invention, visibility, a long life of the light source, minimization of power consumption, and cost reduction can be remarkably realized as compared with the conventional light bulb type illumination type license plate.

Claims (9)

[Claims] 1. An apparatus in which a bulb with an internally illuminated registration number is attached to a cold cathode tube with a trigger. 2. A cold cathode tube device in which a metal such as aluminum is attached to a trigger. 3. A trigger is provided on the side of the cold cathode tube by 1/2 to 1/1.
3 The device is simpler than the conventional one because the trigger acts as a reflecting mirror by attaching it, so that it is possible to illuminate the registration number mark in a concentrated manner, eliminating the need for a reflecting mirror. 4. An apparatus for maintaining a stable luminance even in a cold region because a cold cathode tube with a trigger is not affected by an ambient temperature. 5. An apparatus for adding a light bulb to one side of a cold-cathode tube to accelerate discharge and to achieve a dimming effect. 6. A device for mounting an inverter as a lighting device for a cold cathode tube. 7. A protection device provided with a cold cathode tube for protecting a vehicle from damage from vibration and impact. 8. An apparatus for simplifying maintenance work by providing a connection terminal between a cord from a cold cathode tube electrode and a cord from an inverter. 9. A device which, when a cold cathode tube is damaged or does not light, is made to be recognized by a driver with a warning lamp to prevent no lighting of a registration number mark and a rear-end collision accident.
