[0023] Please refer to Figure 1-2 As shown, the utility model provides an LED lamp board 100, comprising a ceramic substrate 1 and a lamp post 2 mounted and fixed on the ceramic substrate 1. The lamp post 2 is one and is in a long strip shape.

[0024] Specifically, the lamp post 2 includes a lamp strip 21 and a quartz glass lens 22 .

[0025] The light strips 21 include a plurality of light strips 21 , which are electrically connected to each other and can be connected in parallel or in series. The light strips 21 are arranged in parallel to each other and are arranged in sequence along the length direction of the light pole 2 .

[0026] Each of the light strips 21 includes a conductive sheet 211 fixed on the ceramic substrate 1 and an LED chip 212 fixed on a side of the conductive sheet 211 away from the ceramic substrate 1 .

[0027] The conductive sheet 211 may be an FPC, a PCB, or a structure made of other conductive materials, and is used to connect to an external power source. The power of the lamp post 2 is 250-450W.

[0028] In this embodiment, the ceramic substrate 1 is rectangular, with a length of a=40-75 mm and a width of b=30-60 mm. The lamp post 2 is arranged parallel to the wide side of the ceramic substrate 1 and is located in the middle of the ceramic substrate 1 .

[0029] The quartz glass lens 22 is fixed to the ceramic substrate 1 and completely covers the light strip 21. In the present embodiment, the cross section of the quartz glass lens 22 is arc-shaped, the curvature of the arc is 155-175 degrees, and the diameter of the circle where the arc is located is φ=18-22mm. Therefore, compared with the LED light board of the same structural size in the prior art, the LED light board 100 of the present invention has a greater light intensity per unit area, a higher radiation intensity, and a better curing effect through the design of the above-mentioned light strip structure and the shape and size design of the quartz glass lens 22. The curvature of the cross section of the quartz glass lens in the prior art is generally 140-142 degrees, and the diameter of the circle where it is located is φ=16mm. Under the condition of the same number of LED chips, the above-mentioned structural parameters of the present invention have a greater light intensity per unit area, a higher radiation intensity, and a better curing effect.

[0030] In this embodiment, the length of the ceramic substrate 1 is preferably a=62mm and the width is b=52.6mm. The arc of the cross section of the quartz glass lens 22 is 167 degrees, and the diameter of the circle where the arc is located is 20.2mm. Six groups of LED chips 212 are arranged on the conductive sheet 211 of each of the light strips 21 and are arranged at equal intervals from each other. The power of the lamp post 2 is 330W. Compared with the ceramic substrate of the same size and the same number of light strips, the above-mentioned structure can achieve better light intensity per unit area, radiation intensity and factorization effect.

[0031] In this embodiment, the LED lamp board 100 further includes a positioning bracket 3 fixed to the ceramic substrate 1, the lamp strip 21 is arranged within the range of the positioning bracket 3, and the periphery of the quartz glass lens 22 is clamped in the positioning bracket 3 and then fixed by welding. Thus, the quartz glass lens 22 can be fixed on the ceramic substrate 1 more stably, avoiding the problem of the quartz glass lens 22 falling off and loosening due to oxidation after the quartz glass lens 22 is directly welded and fixed on the ceramic substrate 1, thereby improving reliability.

[0032] The ceramic substrate 1 is an ultra-high conductive aluminum nitride ceramic and is made using a eutectic inorganic sealing process, which effectively improves the conduction efficiency of the LED chip 212, thereby improving the lighting efficiency. Preferably, a layer of anti-conductive coating is evenly sprayed on the surface of the ceramic substrate 1 to avoid leakage problems during use and improve reliability.

[0033] In this embodiment, the LED lamp board 100 also includes a metal heat sink 4 which is adhered and fixed to the side of the ceramic substrate 1 away from the light strip 21. The side of the metal heat sink 4 away from the ceramic substrate 1 forms a honeycomb-shaped heat dissipation groove, which effectively increases the heat dissipation area of ​​the metal heat sink 4 and further improves the working stability of the lamp column 2.

[0034] Compared with the related art, the LED lamp board of the present invention is provided with a long strip-shaped lamp post on a ceramic substrate, and the lamp post includes a plurality of lamp strips arranged in parallel with each other and arranged in sequence along the length direction of the lamp post, and a quartz glass lens fixed to the ceramic substrate and completely covering the lamp strip. By designing the cross section of the quartz glass lens to be arc-shaped, the arc of the arc is 155-175 degrees, and the diameter of the circle where the arc is located is 18-22mm, compared with LED lamp boards of the same structural size, the LED lamp board of the present invention has a greater light intensity per unit area, a higher radiation intensity, and a better curing effect.
