Description

LED Strobe Lamp {STEOBE LAMP CONTAINING LED}

The present invention relates to a strobe lamp with a built-in LED, specifically, to be utilized as a low-speed vehicle indicator that must be essentially attached to a road-type agricultural machine, such as short life, high voltage driving, and high cost, which are disadvantages of conventional warning lights. By using LED element, it is possible to manufacture with long life, low voltage driving and low cost, and it is related to strobe lamp with LED built-in heat dissipation structure to solve the heat problem that can be caused by adopting high brightness LED.

The Ministry of Food, Agriculture, Forestry and Fisheries has made mandatory regulations on the attachment of low-speed vehicle indicators to road-produced agricultural machinery from 2011, as the incidence of traffic accidents for farmers due to nighttime driving in dust, dense fog, etc. increases. In addition, the National Academy of Agricultural Science established the standard for warning lights, which are low-speed vehicle indicators of agricultural machinery (Revised Notice No. 2010-4, Article 1: Low-speed vehicle indicators for road-type agricultural machinery).

However, most commercially available warning lights are manufactured and sold without clear criteria for driving conditions (brightness and lighting cycle), and warning lights must be attached to road-type agricultural machinery shipped before 2011. There is no obligation. In addition, the conventional warning lights have a short lifespan, they can only be driven at high voltages, have a high manufacturing cost, and have a short viewing distance when the warning lights are worsened at night or in bad weather.

Therefore, in the case of a low speed vehicle indicator attached to a road-type agricultural machine, it must emit high brightness to ensure visibility even in bad weather such as rainy day or foggy day, and it must not only have a long life but also can be operated at low voltage. It was required to be possible and low cost. No warning lamp has been proposed to meet these conditions.

In particular, mercury bulbs, halogen bulbs, and xenon bulbs used in general warning lamps have a short life span of about 3,000 hours and are easily broken by external shocks. Not only was it the cause, but the problem of shortening the life of the peripheral parts due to the operation at 200-2000V still remained.

The present invention has been made to solve the above problems,

And a power supply circuit.

On the other hand, the microcomputer circuit is programmed to repeatedly turn on / off the LED lamp in order to minimize the heat generated by the LED lamp. After turning the LED lamp on for 0.4 seconds, it should be OFF for 0.8 seconds. At this time, if the LED lamp is turned on for 0.4 seconds and ON for 0.05 seconds again, and OFF for 0.05 seconds four times, the heat generated when the LED lamp is turned on is minimized. Because of the effect, it is desirable to program the program to feel as if the light is on continuously even if it blinks for a short time. The lamp using the optical illusion effect by blinking for a short time by repeating such ON / OFF is called a strobe lamp.

The heat sink 300 is inserted into and fixed to the heat sink inserting fixed hole, and is disposed in communication with a lower portion of the heat sink main body and a pipe-shaped heat sink main body having an open central portion thereof, and having a smaller diameter than the heat sink main body.
