Description

ASSEMBLY TYPE GENERAL-PURPOSE LED STREETLAMP ASSEMBLY TYPE GENERAL-

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to an LED lamp for use in street or outdoor lighting, and in particular, an LED lamp constituting a lamp is formed as an independent unit separated from a lamp cover, It is possible to use the cover for the cover and the conventional lamp cover in general, and the assembled lamp can be assembled so as to form a space for free passage of air between the cover and the LED lamp unit to improve the heat radiation performance, Type indoor type assembly-type outdoor LED light fixture which can prevent lifetime shortening due to an increase in the ambient temperature at the central portion by independently configuring the heat dissipation fins provided for each LED package.

The pole lamps such as street lamps, roads, garden lamps, security lamps, etc. can be used for a long time under harsh conditions and have to satisfy the design performance to take into consideration the urban beauty of day and night. Therefore, Consideration should be given.

In general outdoor, etc., there is a structure in which electric elements are combined with optical and mechanical elements composed of a lamp for securing the height of the light source, an arm for mounting the lamp in the lamp, and a lamp which is attached to the lamp, .

 In addition, a luminaire applied to the outside includes a housing designed for a landscape, a light source installed inside the housing, and a light projecting part which is fastened and assembled to the front surface of the light source so as to be coupled to the housing in a waterproof structure.

In the existing luminaire, HID lamps were mainly used as light sources, and other compact fluorescent lamps and low pressure sodium lamps were used. These light sources are bulb-shaped and coupled to a socket that constitutes an electrical element, thereby providing convenience in that when the life span is reached, the bulb can be loosened from the housing and only the bulb can be replaced.

In addition, most existing outdoor lighting fixtures are constructed to be suitable for existing light sources such as HID lamps, and have safety due to the accumulated technology due to long-term use, but they have a disadvantage of short power consumption and short life span.

On the other hand, the LED lamp as a light source has advantages such as low power consumption, long life, and high efficiency compared to existing light sources. In addition, development of a power LED and a white light source, and improvement of optical performance for improving the light distribution characteristic and uniformity by combining a plurality of LED packages rationally are replaced with a conventional complicated drive circuit for controlling the operation current, Width Method, and so on, it is possible to realize high output by improving the electric performance, and the application to the lighting apparatus replacing the existing light source is expanding accordingly.

However, in order to apply the LED lighting device to outdoor applications, it is required to improve the optical and electrical performance of the LED and to improve the mechanical performance so that it can be used under harsh conditions. At the same time, design performance considering the urban beauty in the nighttime is required.

For example, an LED light fixture combines a plurality of LED packages in series or in parallel and densely arranges them on a small-area PCB to obtain high output by a single light source. Even though the efficiency is improved compared to the conventional light source, 65 to 85% of electricity in the LED chip is converted into heat, so the self heat generation occurs. When the operating temperature is raised above 90 ° C, the light output is decreased, And therefore, the optimum heat dissipation structure must be applied together because it greatly affects the performance and durability of the LED. The heat dissipation structure has a function of discharging heat generated from the LED chip to the outside by increasing a thermal contact area with the outside air. A heat sink such as a heat dissipation fin is applied. In the case of using the housing in consideration of the design, it becomes a factor to reduce the heat radiation performance of the heat sink, and the weight to be increased by the heat sink provides the structural instability to the lamp and the arm installed to the existing light source. There are restrictions on replacing existing light sources with LED luminaires.

As such, the LED lighting for outdoor applications has the basic waterproof performance and durability for use in harsh conditions, the heat radiation performance for stable operation of the LED, light weight for reducing the design load of the lamp and arm, It is required to satisfy the performance. In order to improve the usability of the LED light fixture, a structure capable of appropriately harmonizing these factors, which are factors of performance deterioration, is required.

Various types of outdoor LED luminaires are proposed according to these requirements.

For example, in Korean Patent No. 10-1031308, as shown in FIG. 1A, the entire body 10 and the heat radiating portion 30 are manufactured by aluminum die casting and the heat radiating fin 32 constituting the heat radiating portion is exposed to the outside Housing-casing integrated structure.

Korean Patent Laid-Open No. 10-2012-0080471 discloses a housing-casing-integrated structure LED street lamp configured to surround an LED package by a heat dissipation case, a frame, and a waterproof portion as shown in FIG. 1B.

The above-described technologies have a structure in which the casing constituting the LED module is integrally formed with the housing without using a separate housing for limiting the heat radiation performance, and the heat radiation surface is exposed to the outside. Therefore, compared with the existing structure in which the LED lamp is housed in the housing, Performance is improved.

However, in the above housing integrated type structure, there is a problem that the heat dissipation performance is reduced as dust and the like are stacked on the radiating fin exposed to the outside. Particularly, nitrogen oxides or sulfur oxides due to the exhaust gas of a vehicle are deposited on the surface of the heater to prevent heat radiation due to convection or radiation, so that the heat radiation performance is rapidly reduced and it is difficult to remove these contaminants in the installed state. And efficiency.

In addition, the luminaires design is an important performance factor that affects the cityscape, and the casing for constituting the LED module has to be structurally restricted because the heat dissipation characteristics must be taken into consideration. Although a light metal such as aluminum is diecast, - Even if a casing integrated heat dissipation structure is manufactured, it has a considerable weight in comparison with the conventional light source, so there is a fear that the structural stability may be adversely affected when installing the heat dissipation structure.

Also, in the housing-casing integrated structure, the heat dissipation structure such as the heat dissipation fin is made of a single die casting structure, and the heat is concentrated at the center. Accordingly, the peripheral heat is relatively increased in the central LED package, Resulting in deterioration and shortening the life span.
