Description

High-power projection lamp

Technical Field

The utility model relates to a lamps and lanterns especially relate to a high-power projecting lamp.

Background

The structure of the existing high-power LED spot light refers to FIG. 4. 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 01, mainly advances 01 through well cover and dispels the heat, though cover 01 size can increase the radiating effect in the increase, but when LED light source power was more than 200 watts (high-power), 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 that drive power module B produced at first conducts 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 not enough of prior art, the utility model provides a projecting lamp heat radiation structure that radiating effect is good, the product is small and the LED light source is difficult ageing.

The utility model provides a technical means that its technical problem adopted is: the utility model provides a high-power projecting lamp, includes well cover, is provided with the light source chamber in the well cover, and the installation LED light source of light source intracavity, well cover the place ahead has light source chamber opening, the closing cap has glass panels and front shroud on the light source chamber opening, and the back shroud is installed to well cover rear, be provided with the power chamber in the back shroud, the power chamber includes diapire, annular lateral wall and power chamber opening, install drive power module and fan on the diapire, the air-out direction orientation of fan the lateral wall, the laminating of power chamber opening is in the installation of well cover rear, be provided with thermal-insulated sealing washer between power chamber opening and the well cover.

The utility model has the advantages that: the utility model is provided with the power supply cavity in the rear cover, the driving power supply module is arranged on the bottom wall of the power supply cavity, the heat generated by the driving power supply module is firstly conducted to the bottom wall of the power supply cavity, and the light source cavity is positioned at the tail end of the heat transmission path, so that the LED light source is far away from the heat source to the maximum extent; simultaneously at the fan of power intracavity installation air-out direction orientation lateral wall, can conduct the heat in the air to power chamber lateral wall as early as possible, the rethread lateral wall gives off to the lamps and lanterns outside, again because be provided with thermal-insulated sealing washer between back cover and the well cover, can reduce the heat and transmit to well cover through the back cover, consequently, the utility model has the advantages of the radiating effect is good, and the product is small and the LED light source is difficult for ageing.

Detailed Description

The present invention will be described in further detail with reference to the following drawings and examples. For convenience of description, the present invention uses the light emitting direction of the lamp as "the front" and "the rear" instead, and those skilled in the art can understand that the above definitions and the relative relationships between the components are defined, and do not represent an absolute limitation to the protection scope of the present invention.

Refer to fig. 1 to 4. The utility model provides a high-power projecting lamp, includes the well cover 1 of cask shape, is provided with light source chamber 1A in the well cover 1, installs LED light source A in the light source chamber 1A, and well cover the place ahead has light source chamber opening 10, and the closing cap has glass panels S and the annular front shroud 2 of circle on the light source chamber opening 10, and the front shroud 2 is with on the fixed light source chamber 11 opening of glass panels S. The rear cover 3 of cask shape is installed to well cover 1 rear, is provided with power supply cavity 3B in the rear cover 3, power supply cavity 3B includes diapire 31, annular lateral wall 32 and power supply cavity opening 30. The bottom wall 31 is provided with a driving power module B and a fan 4. The fan 4 is fixed on the bottom wall 31 through a bracket 41, and the air outlet direction of the fan faces the side wall 32. The side wall 32 is provided with an annular heat conduction fin 33 circumferentially surrounding the side wall 32, and the outside of the rear cover 3 is further provided with a heat radiation fin 34. The power cavity opening 30 is attached to the rear portion of the middle cover 1, and a heat insulation sealing ring 5 is arranged between the power cavity opening 30 and the middle cover 1.
