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

Abstract

The invention discloses an LED projection lamp provided with a heat dissipating device. The LED projection lamp comprises an LED projection lamp body, a base internally provided with an accommodatingcavity, a first support tube and a second support tube, wherein the first support tube and the second support tube are arranged on the base upward in the vertical direction and communicate with the accommodating cavity. The LED projection lamp body includes a lamp body internally provided with a heat dissipation cavity and an LED projection lamp panel disposed on the lamp body. The left and rightsides of the lamp body are correspondingly hinged to the first support tube and the second support tube, and the first support tube and the second support tube both communicate with the heat dissipation cavity. A power water pump for sending cooling fluid in the accommodating cavity from the second support tube to the heat dissipation cavity and then enabling the cooling fluid to flow back to theaccommodating cavity through the first support tube is installed on the base. The heat dissipation cavity is internally and rotatably connected with impellers for stirring the cooling fluid. The LED projection lamp is simple in structure and convenient in use, and can effectively realize 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 the economy, the demand for power resources in all walks of life is increasing, and the current situation is that the supply of power is basically in short supply, so saving power has become a necessity. In this case, LED floodlights As a model of energy saving, it has gradually entered people's field of vision. The main features of LED floodlights are low power, high brightness, energy saving, and long service life. Therefore, the proportion of LED floodlights in the lighting market is also increasing. Large, but one of the main factors restricting the development of LED floodlights is the heat dissipation performance of the product. The heat dissipation of common LED floodlight products is mainly completed by external radiators. The quality of external...
