Description

LED module for security light {light-emitting diode module for the security light}

The present invention relates to an LED module for a security light. More specifically, the irradiation angle of the light emitted from the LED lamp of the LED module mounted on the security light is widened so that the light is irradiated evenly throughout the entire area around the security light, so that the light around the security light is illuminated evenly without a reflector. This is about an LED module for security lighting that can brightly illuminate the area.

In general, security lights or street lights are lighting devices installed in automobile roads, squares, parks, housing complexes, factory complexes, etc., and are used to brightly illuminate the area. They are mainly outdoor lighting devices installed outdoors.

Existing security lights and street lights use mercury lamps or sodium lamps as a means of emitting light, but in recent years, the use of lighting fixtures equipped with LED modules has been increasing in terms of eco-friendliness and energy saving.

Since security lights equipped with such LED modules have the characteristics of low power consumption, low glare, long service life, and excellent visibility, security lights equipped with LED modules of various structures are being developed.

However, in the case of security lights equipped with conventional LED modules, the light generated from the LED elements is irradiated almost in a vertical direction with respect to the ground on which the security lights are installed, so it is somewhat insufficient to illuminate the entire surroundings of the security lights.

Of course, in order to solve this problem, a reflector is provided so that the light emitted from the LED device is reflected and irradiated. However, providing a reflector causes another problem of increasing costs, and it causes another problem that increases the cost of the existing reflector. Since the light of the LED element is irradiated by using the same shape of the reflector, there is a problem in that efficient irradiation that preserves the characteristics of the LED element is not achieved.

Looking at the prior art, an LED security light, registered patent number 10-1376079, has been developed, which includes an LED module formed by mounting a plurality of LEDs on a circuit board, an LED module installation part where the LED module is installed, and a device that supplies power. A housing having a power supply installation part where a power supply device is installed, a window cover covering the front of the LED module, a power supply cover covering the power supply installation part, and a plurality of internal heat dissipation fins formed inside the housing. , a heat dissipation fin having a plurality of external heat dissipation fins formed on the outside of the housing, wherein the plurality of internal heat dissipation fins connect a plurality of horizontal heat dissipation fins formed in the horizontal direction of the housing and a pair of adjacent horizontal heat dissipation fins to each other. It is provided with a plurality of vertical heat dissipation fins, and the plurality of vertical heat dissipation fins are each formed at a position corresponding to the position where the LED is installed when the LED module is installed in the LED module installation part.

This prior art can prevent moisture from penetrating into places where electronic components such as LEDs are installed and improve heat dissipation performance.

However, in the case of the prior art, since the LED module that emits light is provided on a flat surface with respect to the housing, the light emitted from the LED module is irradiated perpendicular to the ground where the security light is installed, so the location space where the security light is installed is brightly illuminated. On the other hand, there is a problem that the surrounding area of the security light becomes dark because no luminous light is emitted at all into the space surrounding the security light.

Moreover, in the case of security lights, they are usually installed at a certain distance from each other on the ground, so the space between the security lights becomes dark, so even if the security lights are turned on, the space between the dark security lights and the security lights cannot be visually distinguished, creating a crime-prone space. There are problems that arise.

Of course, a diffuser or reflector can be provided inside the housing to diffuse the LED light to the outside of the security light, but if a diffuser or reflector is provided like this, the cost increases, resulting in a cost burden due to the installation cost of the security light. There is another problem.
