Description

LED street light structure

technical field

The utility model relates to an LED street lamp structure, in particular to a street lamp manufactured by utilizing the high brightness of the LED lamp, which strengthens the cooling effect and prolongs the working life of the LED lamp.

Background technique

Known street lamps require high brightness, so most of them use high-power, large-size illuminants, and then dissipate heat through the housing of the street lamp. However, this known method has the following disadvantages after implementation:

1. It is known that street lamps use high-power and large-size illuminants, so the power consumption is quite astonishing. When energy is increasingly scarce and precious, it is not a temporary choice.

2. Due to the high power of the known street lamps, the heat generated by the luminous body is not a problem. However, if only the shell is used for heat dissipation, the temperature of the shell may be too high or the luminous body may be burned. .

Due to the above defects, it is difficult for the heat generated by the operation of the luminous body of the traditional street lamp to dissipate through the casing, which also causes the temperature of the casing to be too high or the luminous body to burn out. Therefore, based on the disadvantages of traditional street lamps, the author of this case created the application for "Heat Dissipation Structure Improvement" of China Utility Model Patent No. 200820000871.3, which uses an aluminum shell with good heat dissipation for heat dissipation of street lamps.

The heat pipe frame is a stabilizer box with multiple fins on both sides of a heat sink with main heat dissipation fins, and a plurality of heat dissipation lamp groups are pierced at the bottom;

An auxiliary heat dissipation and air guide device is installed above the heat pipe frame.

From the above description, the utility model has the following beneficial effects:

1. The structure of the LED street lamp of this utility model is aimed at the heat dissipation demand after the power is increased to about 30W. Then, the auxiliary heat dissipation and air guide device is used above the heat pipe frame set on the top of the lamp housing cover, so that the LED street lamp can operate at high power and large The size of the street lamp needs to have better heat dissipation effect.

2. In addition to the main heat dissipation fins of the heat pipe frame, the utility model cooperates with multiple fins on the upper end of the stabilizer box installed on both sides of the heat dissipation seat to increase the heat dissipation surface, thereby rapidly dissipating heat.

3. The utility model is used for an auxiliary heat dissipation and air guide device. The auxiliary heat dissipation and air guide device is not only made of aluminum itself to assist heat dissipation, but also can force air into the main heat dissipation fins of the heat pipe frame to strengthen the heat dissipation effect and prolong the heat dissipation. LED lamp working life.
