Description

Technical Field

[0001] The utility model relates to the technical field of LED backlight sources, in particular to a backlight source for indoor and outdoor decoration with good protection effect. Background Art

[0002] When designing interior and exterior decorations, designers often use various luminous lighting fixtures to enhance the beauty and ambiance of the space. Currently, popular luminous lighting fixtures on the market mostly use LEDs as their backlight source. Due to their high brightness, low energy consumption, and long lifespan, LED light sources have become the preferred choice for enhancing the performance of luminous lighting fixtures. However, when these luminous lighting fixtures are used outdoors, they are inevitably exposed to various weather conditions, especially rainfall. Once rainwater seeps into the internal structure of the luminous fixture, this infiltrated moisture can potentially damage the LED light source over time. Prolonged exposure to humidity can cause LED light sources to short-circuit, dim, or even fail completely, impacting the normal use and lifespan of the entire luminous fixture. Therefore, when designing and installing outdoor luminous lighting fixtures, waterproofing measures must be taken to ensure proper operation in all weather conditions, extending their service life and maintaining their aesthetic appeal. To this end, we propose a highly protective backlight source for indoor and outdoor decoration. Utility Model Content

[0003] The purpose of the present utility model is to solve the problem that when luminous lighting fixtures are placed in outdoor environments for use, they will inevitably encounter various weather conditions, especially rainy weather. Once rainwater penetrates into the internal structure of the luminous lighting fixture, over time, the infiltrated moisture will cause potential damage to the LED light source inside the luminous lighting fixture. When exposed to a humid environment for a long time, the LED light source may short-circuit, reduce brightness, or even fail completely, thereby affecting the normal use and life of the entire luminous lighting fixture. Therefore, when designing and installing outdoor luminous lighting fixtures, waterproof measures must be considered to ensure that they can work normally under various weather conditions to extend their service life and maintain their aesthetic effects. The present utility model provides a backlight source for indoor and outdoor decoration with good protective effects.

[0009] Furthermore, the backlight base plate, the light bar fixing groove and the water guide plate are all made of aluminum alloy, and the upper end of the water guide plate is fixedly connected to a water-absorbing cotton pad.

[0010] Furthermore, fixing ears are fixedly connected to the upper and lower sides of both sides of the backlight base plate, and the plurality of fixing ears are provided with bolt fixing holes.

[0011] Furthermore, the front side of the backlight base plate is fixedly connected to an acrylic light-diffusing plate by self-tapping screws, and the contact surface between the backlight base plate and the acrylic light-diffusing plate is coated with transparent glass glue.

[0012] The beneficial effects of the utility model are as follows:

[0013] 1. The utility model provides a backlight base plate, and multiple LED light strips are fixed side by side in the light strip fixing groove on the front side of the backlight base plate.

Through the provided power strip, the power strip is provided with power supply contacts at the upper ends corresponding to the multiple LED light strips, and the power supply contacts are in contact with the power contacts on the LED light strip to supply power to the multiple LED light strips. The independent sealing structure of the power strip reduces the probability of water entering the power strip and the power connection position of the LED light strip. Through the provided multiple air communication grooves and the staggered water guide plates in the multiple air communication grooves, water vapor enters the air communication grooves, and the condensed water vapor is adsorbed on the inner wall of the backlight base plate and flows down under the action of gravity. It can flow down along the staggered water guide plates, thereby assisting the water guide plates in cooling and dissipating heat. The water guide plates are fixedly connected to the outer walls of the light strip fixing grooves, which can assist the LED light strips in the light strip fixing grooves in dissipating heat.

[0014] 2.

Through the ventilation fan set up, the air flow output by the ventilation fan can flow along the radial gaps between the back heat exchange fins, further improving the heat exchange efficiency of the back heat exchange fins.

[0015] 3. The utility model is made of aluminum alloy to facilitate the heat dissipation when the LED light strip is emitting light. By arranging a water-absorbing cotton pad on the upper end of the water guide plate, the water guide plate's ability to intercept water vapor is improved, and the auxiliary heat dissipation effect of the water guide plate is improved. The lower end of the water guide plate is exposed to reduce the impact on the heat dissipation capacity of the water guide plate when there is no water vapor. BRIEF DESCRIPTION OF THE DRAWINGS
