A kind of LED flood light with cooling device

Abstract

The invention discloses an LED projection lamp provided with a heat dissipation device, which comprises an LED projection lamp and a base provided with an accommodating cavity inside; Connected first support tube and second support tube; the LED floodlight includes a lamp body with a heat dissipation cavity inside and an LED floodlight panel arranged on the lamp body; the left and right sides of the lamp body respectively hinged on the first support tube and the second support tube, and both the first support tube and the second support tube communicate with the heat dissipation cavity; The cooling liquid in the housing chamber is sent to the cooling chamber by the second support pipe and then flows back to the power pump of the housing chamber by the first support pipe; Liquid impeller; the LED floodlight is not only simple in structure, easy to use, but also can effectively achieve heat dissipation.

Description

Technical field[0001]The invention relates to the technical field of LED lamps, in particular to an outdoor LED projection lamp provided with a heat dissipation device.Background technique[0002]With the development of economy, the demand for power resources in all walks of life is increasing, and the current situation is that power is basically in short supply, so it is inevitable to save power. In this case, LED floodlights As a model of energy-saving, it has gradually entered people’s field of vision. The main characteristics of LED floodlights are low power, high brightness, energy saving, and long service life. Therefore, LED floodlights have become more and more in the lighting market. However, one of the main factors restricting the development of LED flood light is the heat dissipation performance of the product. The heat dissipation of common LED flood light products is mainly completed by external radiators. The quality of external radiators directly determines The life of ...

AI Technical Summary

Problems solved by technology

At present, many industries have new requirements for LED lighting. For example, LED floodlights used in outdoor large-scale stage parties require a large number of lamp beads, and the length of the aluminum substrate is long enough. Due to the increase in the number of lamp beads, the heat The heat generated is also quite large, and it is difficult to solve the heat dissipation problem simply by relying on ordinary external radiators, and it needs to invest more costs to use an external radiator with a particularly good effect. These have caused certain problems for production-oriented enterprises. ;In addition, the LED floodlights used in outdoor large-scale stage parties are easily blown down by the wind in strong winds, thus affecting normal use
