Description

LED tri-proof bracket light

technical field

The utility model relates to a lighting device, in particular to an LED three-proof bracket lamp, which belongs to the technical field of semiconductor lighting.

Background technique

At present, the pearlescent effect of LED lamps can reach 1-15 lumens/watt after improvement, and the light has good monochromaticity and narrow spectrum, and can directly emit colored visible light without filtering. LED lamps are high-efficiency and energy-saving lamps with a long service life. The normal service life of LED lamps can reach about 3-5 years, which can greatly reduce the maintenance costs of lamps and avoid frequent replacement of lamps. Existing disclosed three-proof bracket lamp, one, adopts cold-cathode tube light source or LED light source to make. Because cold cathode lamp tubes are heavy and costly, the manufacturing process is complicated and the actual production cycle is long. The LED three-proof bracket light adopts a plastic shell, and inserts aluminum profiles, LED light sources, aluminum substrates, and driving power inside the plastic shell. Due to design defects, the LED tri-proof bracket light cannot dissipate heat from the LED light source inside its plastic shell, resulting in shortened life of the entire light fixture.

In view of the above-mentioned present situation, the purpose of this utility model is to avoid the deficiencies of the prior art, and propose a LED three-proof bracket lamp with good light output rate and heat dissipation function.

The technical solution of the utility model is: an LED three-proof bracket lamp, including an LED light source and a PCB board. The end cover is connected with the lampshade of the PC shell; wherein a reflective lens and a waterproof rubber ring are sequentially arranged between the LED light source, the PCB board and the PCB board fixing profile from top to bottom; the two sides of the PCB board fixing profile are distributed with Cooling holes in the profile; there are shell cooling holes distributed on both sides and bottom of the lampshade of the PC shell.

In the present model, the reflective lens is provided with a protruding groove for installing the LED light source and the PCB board.

Further, the PCB board fixing profile is provided with a groove for installing the LED light source and the PCB board.

Further, the PCB board fixing profile is provided with a groove for installing a waterproof rubber ring.

The beneficial effects of the utility model are: through the PC housing lampshade of the LED three-proof bracket lamp and the two sides of the PCB board fixing profile respectively, there are light-transmitting heat dissipation holes, and at the same time, between the LED light source and the PCB board and the PCB board fixing profile A reflective lens and a waterproof rubber ring are arranged in turn in order to meet the light extraction efficiency and heat dissipation performance of the LED light source. In addition, due to the use of waterproof rubber rings and reflective lenses to compress the LED light source and PCB board, the protection level of the internal light source and circuit parts can reach IP67.
