The utility model discloses a floodlight, comprising a middle cover, a light source cavity is arranged in the middle cover, an LED light source is installed in the light source cavity, a rear cover is installed behind the middle cover, a power supply cavity is arranged in the rear cover, and the The power supply cavity includes a bottom wall, an annular side wall and an opening of the power supply cavity, the drive power module is installed on the bottom wall, the opening of the power supply cavity is installed behind the middle cover, and the opening of the power supply cavity and the middle cover are installed. A heat-insulating sealing plate is arranged between the covers. Because the power supply cavity is set in the rear cover, the driving power module is installed on the bottom wall of the power supply cavity, and the heat generated by it is firstly conducted to the bottom wall of the power supply cavity, and the LED light source is kept away from the heat source to the greatest extent; The thermal isolation of the heat-insulating sealing plate from the middle cover can reduce the heat transfer to the middle cover. Therefore, the utility model has the advantages of good heat dissipation effect, small product volume and the LED light source is not easy to age.
Description
Technical Field
The utility model relates to a lamps and lanterns especially relate to a 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 defects of the prior art, the utility model provides a projecting lamp 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 projection 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, and the laminating of drive power module is in on the diapire, the laminating of power chamber opening is in well cover rear installation, be provided with thermal-insulated closing plate between power chamber opening and the well cover.
The utility model has the advantages that: because the power supply cavity is arranged in the rear cover, the driving power supply module is attached to the bottom wall of the power supply cavity, 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; set up thermal-insulated closing plate and well cover thermal isolation on the back shroud opening simultaneously, can reduce the air convection current transmission to well cover of heat through back shroud casing and power intracavity, consequently, the utility model has the advantages of the radiating effect is good, and the product is small and the difficult ageing of LED light source.

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 "front", otherwise "rear", and those skilled in the art can understand that the above definition only represents the relative relationship between the components, and does not represent an absolute limitation to the protection scope of the present invention.
Refer to fig. 1 to 3. The utility model provides a projecting lamp, includes the well cover 1 of the cask shape of making by the material that does not conduct, is provided with light source chamber 1A in the well cover 1, installs LED light source A in the light source chamber 1A. The non-heat-conducting material is not absolutely non-heat-conducting, but rather has poorer heat conductivity than the commonly used heat-conducting materials such as metal and the like, such as plastic, rubber or fiber and the like. The front of the middle cover 1 is provided with a light source cavity opening 10, the light source cavity opening 10 is covered with a glass panel S and a circular front cover 2, and the front cover 2 fixes the glass panel S on the opening of the light source cavity 10. A cylindrical rear cover 3 is arranged at the rear part of the middle cover 1, a power supply cavity 3B is arranged in the rear cover 3, and a heat radiation fin 33 is arranged at the outer side of the rear cover 3. The power supply chamber 3B comprises a bottom wall 31, an annular side wall 32 and a power supply chamber opening 30. The driving power module B is attached to the bottom wall 31. The power supply cavity opening 30 is attached to the rear portion of the middle cover 1, and a heat insulation sealing plate 4 is arranged between the power supply cavity opening 30 and the middle cover 1.
The utility model is provided with the power supply cavity in the rear cover, the driving power supply module is attached to 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; set up thermal-insulated closing plate and well cover thermal isolation on the back shroud opening simultaneously, can reduce the air convection current transmission to well cover of heat through back shroud casing and power intracavity, consequently, the utility model has the advantages of the radiating effect is good, and the product is small and the difficult ageing of LED light source. The middle cover is made of a non-heat conducting material, so that heat can be further reduced from being conducted to the LED light source through the middle cover.
The above description of the specific embodiments is only the preferred embodiments of the present invention, and does not represent the limitation of the protection contents of the present invention, and any technical solutions that can be obtained by normal reasoning of the ordinary technicians in the spirit of the present invention are the protection scope of the present invention.
