Abstract

The present invention relates to an LED lighting device having a rapid heat dissipation structure, by directly connecting the LED module to the inner bottom surface of the outer heat dissipation cover member having excellent thermal conductivity, thereby minimizing the length of heat conduction, thereby greatly increasing the heat dissipation effect of the outside air, and the heat dissipation cover An object of the present invention is to provide an LED lighting device having a rapid heat dissipation structure in which a plurality of heat dissipation ribs are protruded finely on an upper surface of the member so that high heat dissipation effects can be expected.

Applying the present invention, since the LED module is directly connected to the lower surface of the heat dissipation cover member, heat generated when driving the LED module is quickly transferred to the heat dissipation cover member directly connected to the outside air, so high air cooling effect can be expected. Since it consists of a thin film shape projecting on the upper surface of the cover member, the contact area between rainwater, frost, wind, etc. is very large, and thus the heat dissipation effect is high. Since there is no heat dissipation in the interior, the temperature inside the apparatus in which the LED module is configured does not rise, and thus an excellent thermal environment can be provided.

Description

LED LIGHTING DEVICE WITH FAST RADIATING STRUCTURE}

The present invention relates to an LED luminaire having a rapid heat dissipation structure, and more specifically, by directly connecting the LED module to the inner bottom surface of the outer heat dissipation cover member having excellent heat conductivity, thereby minimizing the length of heat conduction, thereby greatly increasing the heat dissipation effect from the outside air. The present invention relates to an LED lighting device having a rapid heat dissipation structure in which a high heat dissipation effect can be expected by forming a plurality of heat dissipation ribs on the upper surface of the heat dissipation cover member.

As is well known, various lightings including headlamps, rear combination lamps, and streetlights of automobiles generally use a general bulb as a light source.

However, bulbs as described above have a short service life and low impact resistance, and therefore, there is a tendency to use high brightness LEDs (LEDs) having excellent impact resistance while greatly extending the service life in the near field.

In particular, the high-intensity LED as described above can be used as a light source for various lights, including headlamps, rear combination lamps and street lights of automobiles, and the scope of application thereof can be very broad.

As the high-intensity LED as described above generates very high heat when turned on, there are many difficulties in applying and designing it by the exothermic temperature of high heat.

Therefore, in the related art, as shown in FIG. 1, the cover 13 positioned on the rear surface of the substrate 11 to which the plurality of LEDs 2 is attached is formed of a metal material, or the plurality of heat dissipation and atmospheric circulation on the cover 13. The holes 13a are formed to dissipate heat generated from the LED 2 by natural heat dissipation.

However, the heat dissipation structure of the LED light emitting lamp by the natural heat dissipation as described above is limited in its heat dissipation amount, and the heat generated from the LED 2 is higher than the heat dissipation heat, so that the lamp is constantly warmed. In the design of the product, expensive flame retardant and non-flammable materials were selected, as well as an uneconomical problem of using a resin or metal material that does not cause thermal deformation or shrinkage even at high temperatures.

In particular, since LEDs and various electrical connection mechanisms have fragility from high temperatures, they have been a cause of shortening their service life.

Therefore, recently, an LED lighting device having a heat dissipation structure as shown in FIG. 2 has been developed.

2 is a cross-sectional view showing an LED lighting device having a heat dissipation structure according to another embodiment of the prior art.

Referring to this, an aluminum substrate 110 to which a plurality of LEDs 102 for irradiating high brightness light are mounted, and is mounted on the aluminum substrate 110, is transferred from the aluminum substrate 110 by a heat generation action of an internal refrigerant. At least one heat pipe (heat pipe) for dissipating the received heat to the upper portion and a plurality of refrigerant plates 120 and the lower end is mounted to the refrigerant plate 120 to transfer the heat radiated from the refrigerant plate 120 to the upper end and a plurality of 'horizontal heat dissipation fins' 140 coupled to the plurality of heat pipes 130 to dissipate heat transferred from the heat pipes 130 to the outside.

The refrigerant plate 120 radiates heat received from the aluminum substrate 110 to the upper portion while the refrigerant circulating up and down inside the vaporization condensation. The refrigerant plate 120 is, for example, Nano of CELSIA, USA. It can be implemented by Spreaders and the like and its operation principle and structure are already known to those skilled in the art, detailed description thereof will be omitted.

In addition, the coolant plate 120 is screwed to the aluminum substrate 110 by a fastening screw P1. That is, the fastening screw (P1) is screwed into the fastening hole (110a) formed in the aluminum substrate 110 and the fastening hole (120a) formed in the coolant plate 120 to the aluminum substrate 110 and the coolant plate 120. Fasten.

The heat pipe 130 is preferably mounted to be located directly above the plurality of LEDs 102. This is because heat generated from the LED 102 can be transmitted to the outside more efficiently. The heat dissipation cover 160 dissipates heat of the LED 102 transferred through the coolant plate 120 and the heat pipe 130 by an air cooling method.

The reinforcement part 162 which protruded in the inner surface of the heat dissipation cover 160 is comprised, and the fastening screw P2 which fastens the said heat pipe 130 and the heat dissipation cover 160 is employ | adopted.

Reference numeral (C) is known as a 'cover lens' to function to pass the light irradiated from the LED 102 and to prevent foreign matter from entering the interior of the lamp. Reference numeral B1 denotes a fixed pipe for fixing the lamp to a fixture such as a street lamp supporter. The heat generated from the LED 102 is transferred to the aluminum substrate 110, the heat transferred to the aluminum substrate 110 is transferred to the coolant plate 120, the coolant plate 120 received heat from the aluminum substrate 110. ) Transfers heat to the top by the action of the refrigerant circulating inside.

The heat transferred to the upper portion of the coolant plate 120 is transferred to the bottom of the heat pipe 130, and at this time, the heat pipe 130 operates to transfer heat to the top. The heat transferred to the top while the heat pipe 130 is operating is conducted to the heat dissipation cover 160 and is discharged to the outside.

In addition, since the aluminum substrate 110 is directly coupled to the heat dissipation cover 160, heat of the aluminum substrate 110 is directly conducted to the heat dissipation cover 160 to be discharged to the outside.

However, the LED lighting device having the heat dissipation structure is a structure that radiates heat of the LED 102 generated from the aluminum substrate 110 through the heat dissipation fin 140 located in the inner space of the heat dissipation cover 160, the illumination Since the temperature of the internal space of the apparatus rises, there is a problem that the aluminum substrate 110 and the LED 120 driving module are located in a poor thermal environment, thereby making it difficult to obtain a desired heat dissipation effect.

In addition, the LED lighting device having a conventional heat dissipation structure ultimately re-transfers the heat transferred through the aluminum substrate 110 through the heat pipe 130 to reach the heat dissipation cover 160, and the heat dissipation cover 160 Although it is a method of cooling the air by being connected to the outside air through a), it is difficult to expect effective heat dissipation because the heat conductivity is inevitably lowered because heat is transmitted through the heat pipe 130 having a narrow and long length.

On the other hand, the conventional LED lighting fixture having a heat dissipation structure is composed of a complex configuration, such as the heat dissipation cover 160 and the heat pipe 130 and the aluminum substrate 110, there is a problem that the assembly is greatly degraded economically very disadvantageous.
