Problems solved by technology

[0002] Most of the existing LED light source modules adopt the structure of simply placing the LED on the circuit board. The disadvantage is that the integrity is poor, and the problem of dustproof and waterproof is not considered. It can be used indoors for a period of time. After a period of time, the dust and poor contact between the LED and the circuit board often affect its normal operation. Infiltration and even poor contact affect its normal operation. These LED light source modules have poor reliability and short service life.

Embodiment 1

[0011] The structure diagram of the present invention is as figure 1 As shown, it includes several LEDs (1), circuit boards (2), wherein the circuit board (2) includes a bottom plate (21) and a wiring layer (22), pins and power lines (3) of several LEDs (1) (4) Welded on the wiring layer (22) of the circuit board (2), several LEDs (1) are connected in series and / or in parallel on the power line (3) (4), and the upper end surface of the wiring layer (22) A waterproof insulating layer (4) is provided to cover the entire surface of the LED (1) and the welding points of the LED (1) and the power line (3) (4).

[0012] The cross-sectional shape of the circuit board (2) is regular or irregular polygonal or curved. The above LEDs (1) include several rows and columns distributed on the wiring layer (22) of the circuit board (2) or include several rings distributed on the wiring layer (22) of the circuit board (2). In this embodiment, the cross-sectional shape of the circuit board (2...

Embodiment 2

[0014] The structure of the present invention is the same as that of Embodiment 1, the difference is that the cross-sectional shape of the circuit board (2) is a regular hexagon, and 6 LEDs (1) are circularly distributed on the wiring layer of the circuit board (2) (22) on.

Embodiment 3

[0016] The structure of the present invention is the same as that of Embodiment 1, except that the cross-sectional shape of the circuit board (2) is circular, and 15 LEDs (1) are divided into two circular rings and are evenly distributed on the wiring layer of the circuit board (2) (22) on. There are 6 LEDs (1) distributed in the inner ring, and 9 LEDs (1) distributed in the outer ring.

Abstract

The invention relates to a lighting module with the LED as light resource, which comprises several LED (1), and a circuit board (2). Wherein, the circuit board (2) comprises a bottom plate (21) and a wire distributed layer (22); the pins of LED (1) and the power wire (3) (4) are welded on the wire distribution layer (22) of circuit board; some LED (1) is series and / or parallel with the power wire (3) (4) and the upper end face of wire distribution layer (22) has a water-proof insulation layer (4) for covering its whole surface, and packing the pins of LED (1) and the welding points of power wire (3) (4). The invention can avoid the disable contact between the LED and the circuit board caused by accumulated dust and avoid the rain to confirm normal operation. The invention has better reliability, long service life, reasonable structure, and better properties.

Description

Technical field: [0001] The invention is a lighting module with LED as the light source, which can be used not only for indoor lighting fixtures and outdoor lighting fixtures, but also for being installed in billboards and road signs, and belongs to the transformation technology of LED light source modules. Background technique: [0002] Most of the existing LED light source modules adopt the structure of simply placing the LED on the circuit board. The disadvantage is that the integrity is poor, and the problem of dustproof and waterproof is not considered. It can be used indoors for a period of time. After a period of time, the dust and poor contact between the LED and the circuit board often affect its normal operation. Penetration and even poor contact affect its normal operation. These LED light source modules have poor reliability and short service life. Invention content: [0003] The purpose of the present invention is to overcome the above disadvantages and provi...
