Heat radiation structure of projecting lamp

Technical Field

The utility model relates to a lamps and lanterns especially relate to a heat radiation structure of projecting lamp.

Background

The structure of the existing high-power LED spot light refers to FIG. 5. The LED lamp comprises a middle cover 01, wherein the inner cavity of the middle cover 01 is divided into a light source cavity 01A and a power supply cavity 01B by a partition plate 011. The LED light source module is characterized in that an LED light source A is installed on a partition plate 011 in the light source cavity 01A, and a driving power supply module B is installed on a partition plate 01 in the power supply cavity 01B. The opening of the light source cavity 01A is sealed and provided with a glass panel S, the glass panel S is fixed on the middle cover 01 through a front cover 02, and the opening of the power supply cavity 01B is provided with a rear cover 03. The heat that drive power module B work produced at first conducts to well cover heat dissipation, mainly dispels the heat through well cover, though cover 01 size can increase the radiating effect in the increase, but when LED light source power was more than 200 watts, cover 01 size was disproportionated to promoting the radiating effect in the increase. In addition, because LED light source A and drive power module B install respectively in baffle 011 both sides, the heat direct conduction that drive power module B produced is to LED light source A, and LED light source A temperature is higher, leads to it to be changeed ageing and luminous colour drift. Therefore, the existing high-power projection lamp has the defects of poor heat dissipation effect, large volume, easy aging of an LED light source and the like.

Disclosure of Invention

In order to overcome the defects of the prior art, the utility model provides a radiating structure of a projecting lamp which has good radiating effect, small product volume and difficult aging of a LED light source.

The utility model provides a technical means that its technical problem adopted is: the utility model provides a heat radiation structure of projecting lamp, includes well cover, is provided with the baffle in the well cover and cuts apart into light source chamber and power chamber with its inner chamber, and light source intracavity installation LED light source, the drive power module is installed to the power intracavity, the closing cap has the front shroud on the light source chamber opening, the closing cap has the back shroud on the power chamber opening, the drive power module passes through the stabilizer blade installation on the baffle of power intracavity, the clearance has between drive power module and the baffle, install the air-out direction orientation on the drive power module the fan of back shroud.

The utility model has the advantages that: the utility model discloses because the clearance has between drive power supply module and the next door, the heat that drive power supply module produced can not direct conduction to well cover to install the fan on drive power supply module, blow the heat of power intracavity to the back shroud, mainly dispel the heat through the back shroud, the LED light source is heated still less, and the radiating effect is better, can reduce the product volume and delay the LED light source ageing.
