Background technique

After decades of technological improvement, LED light source has become the mainstream product of modern lighting with its advantages of high luminous efficiency, low power consumption, long service life, strong safety and reliability, and environmental protection. Due to the good light-gathering performance and high brightness of LED illuminants, LED light sources are more and more used in key lighting fields.

The LED floodlights in the prior art include a casing and a cover plate, and electronic assemblies, light-emitting chips and reflectors are arranged in the casing. The cover plate includes a fixed frame and a lampshade. The fixing frame is fixed to the housing, usually by screws. The lampshade is sandwiched between the fixed frame and the housing. The connection between the lampshade and the housing is also provided with a waterproof sealing ring. This kind of prior art LED floodlight has the following defects: the lampshade is fixed on the shell through the fixing frame, which is troublesome to install, and the fixing frame needs to be molded separately, which increases the production cost and production process, and the lampshade A sealing ring needs to be provided between the housing and the housing to waterproof, which is cumbersome to install and has poor waterproof effect; the entire LED floodlight has many parts, thick thickness, heavy weight and poor waterproof effect.

Utility model content

The technical problem to be solved by the utility model is to provide a light and thin high-waterproof LED floodlight. The LED floodlight is easy to install, simple in structure, less in parts, lighter and thinner, and has a good waterproof effect.

The technical solution of the utility model is to provide a light and thin high waterproof LED floodlight with the following structure, including a housing and a lampshade, the housing is provided with a reflector and a light source; the lampshade is directly sealed and fixed on the open end of the housing.

After adopting the above structure, the frivolous and highly waterproof LED floodlight of the present invention has the following advantages compared with the prior art:

Since the lampshade of the frivolous and highly waterproof LED floodlight of the present utility model is directly sealed and fixed on the opening end of the housing, the fixed frame and sealing ring in the LED floodlight of the prior art are omitted, and the structure is simple , reduce production process, reduce production cost, good waterproof effect and easy installation. The entire LED floodlight has better parts, thinner thickness and better waterproof effect.

As an improvement of the utility model, the lampshade is sealed and fixed on the opening end of the housing by glue. After adopting this structure, the waterproof effect of the lampshade is better, and the installation is more convenient.

As another improvement of the present invention, a limit step is provided on the side wall of the opening end of the housing; the edge of the lampshade is limited on the limit step. After adopting this structure, the edge of the lampshade is installed on the limit step, and the space between the lampshade and the limit step is fixed and sealed by glue, which is convenient for installation.

As another improvement of the present utility model, the shell is made of magnesium alloy. After adopting this structure, the casing is light in weight and has good heat dissipation effect.

As another improvement of the present utility model, a plurality of cooling ribs are provided on the back of the housing, and the cooling ribs are integrally formed with the housing. After adopting this structure, the heat dissipation ribs can improve the heat dissipation effect of the LED floodlight.

As another improvement of the present utility model, the back of the housing is provided with a waterproof joint. After adopting this structure, the waterproof joint is hidden on the back of the housing, and the waterproof joint cannot be seen from the front of the housing. The overall structure is neat and compact, which is convenient for packaging and can reduce packaging and transportation costs.

As another improvement of the present invention, the LED floodlight also includes a mounting bracket; the two ends of the mounting bracket are respectively fixed on the heat dissipation ribs on the two sides of the back of the housing; The two ends of the installation bracket do not protrude from the two ends of the lampshade; the lower end of the installation bracket does not protrude from the lower end of the lampshade. After adopting this structure, the entire installation bracket can be hidden on the back of the casing, the overall structure is neater and more compact, and the packaging is more convenient and the packaging and transportation costs are reduced.

As another improvement of the present utility model, an outwardly protruding heat layer is provided at the position corresponding to the light source on the back of the housing. After adopting this structure, the thickness of the heat layer is thicker than that of the casing, which can better conduct the heat generated by the light source, so that the heat dissipation effect is better.

As another improvement of the present utility model, the light source is an LED chip light source. After adopting this structure, the LED chip light source emits light uniformly, has high safety, and does not need to install a light emitting cover, so that the luminous flux can be increased.

As another improvement of the present invention, the edge of the inner surface of the lampshade is provided with a decorative edge. After adopting this structure, the decorative edge can be used to hide some structures between the edge of the lampshade and the junction of the housing, so that the LED floodlight looks neater from the front of the lampshade and has a better visual effect.
