Embodiment Construction
[0018] In order to make it easy to understand the technical means, creative features, objectives and effects achieved by the present invention, the present invention will be further explained below in conjunction with the drawings and specific embodiments.
[0019] Such as figure 1 , figure 2 , image 3 As shown, the driverless LED backlight and side-light light bar proposed by the present invention includes a strip-shaped heat sink body 1 with a substrate 2 provided on the front of the strip-shaped heat sink body. The substrate extends along the length of the bar-shaped heat sink body and passes The thermal conductive glue 3 is fixed on the strip-shaped heat dissipation frame. A set of LED luminous bodies 4 are arranged on the substrate. The LED luminous bodies are arranged in sequence along the length of the substrate. The strip-shaped heat dissipation frame has ribs 5 on both sides. The strips are arranged on both sides of the substrate and the LED luminous body. The ribs are ...

The invention provides a non-driven LED (Light Emitting Diode) backlight and sidelight light bar. The light bar comprises a strip-shaped cooling frame body, wherein the frontage of the strip-shaped cooling frame body is provided with a substrate, the substrate extends along the length direction of the cooling frame body and is fixed on the strip-shaped cooling frame body through heat-conducting glue, and the substrate is provided with a group of LED illuminants; lenses are arranged in the LED illuminants and proper shining angles are achieved by performing secondary grading, all LED illuminants are sequentially arranged long the length direction of the substrate, the two sides of the strip-shaped cooling frame body are provided with ribs and all ribs are arranged at the two sides of the substrate and the LED illuminants; the ribs are bent to the frontage of the strip-shaped cooling frame body, a mounting slot is formed in the frontage of the strip-shaped cooling frame body, and is filled with a pouring sealant, and the substrate and the bottom parts of the LED illuminants are sealed by the pouring sealant; the top parts of the LED illuminants protrude out of the sealing sealant, the two ends of the strip-shaped cooling frame body are respectively provided with end covers which sleeve the end parts of the strip-shaped cooling frame body, connecting pieces are arranged outside all end covers, and waterproof connecting tips are arranged in the end covers.
Description
Technical field [0001] The invention relates to an LED lamp, in particular to a driverless LED backlight and a side-light lamp bar. Background technique [0002] Advertising light boxes are commonly used outdoor propaganda tools. Such advertising light boxes generally use internal lighting. In order to save energy, advertising light boxes with LED light bars as backlight sources are more and more widely used. Commonly used LED light bars need to be equipped with a matching drive power supply, and the drive power supply is relatively easy to be broken, and the installation and maintenance are cumbersome, which is not conducive to the application in advertising light boxes. Therefore, it is necessary to modify the structure of this LED light bar. Make improvements to overcome the above shortcomings. Summary of the invention [0003] The purpose of the present invention is to provide a driverless LED backlight and side-light light bar, which is easy to install. [0004] The technical...
