In the development of the stage lighting industry, the structure and performance of the lamp body are very important. Most of the stage beam computer moving head lights on the market are indoor lights. If it needs to be used outdoors, the lamp body cannot prevent ultraviolet rays and sudden heavy rain. The damage caused by natural factors to the lamp body has also brought inconvenience to the majority of users. Because the beam computer moving head light uses a hot light source discharge bulb, the light source generates a lot of heat, so the heat dissipation of the light body can only use a fan, and the method of convection is used to quickly dissipate heat to cool down the light body. This cannot prevent the water from splashing into the lamp body and causing damage to the light source and circuit boards inside the lamp body. Therefore, there is still no waterproof beam computer moving head lamp with a hot light source developed in the industry.

At present, the waterproof computer lights in the industry can only be applied to lights with LED cold light sources as the luminous body. The fully sealed method is used to meet the waterproof requirements, and then the method of large-area heat sink is adopted to solve the problem of lamp body by using metal heat conduction. Due to the heat dissipation problem of this kind of heat dissipation method, because the heat dissipation speed is too slow, it cannot meet the heat dissipation requirements of the discharge bulb of the hot light source at all, so it cannot be used.

Detailed ways

Below in conjunction with accompanying drawing, utility model is described in further detail:

The utility model comprises a base 2, a "U"-shaped arm 3 mounted on the base 2 and capable of rotating relative to the base, and a lamp body 1 mounted on the "U"-shaped arm 3 and capable of rotating relative to the "U"-shaped arm 3. The lamp body described above includes two parts, the lamp cap and the lamp body. The lens 1-3 and the lens cover constitute the lamp cap part. Shaft sleeves 1-10 etc. form the lamp body part, wherein bulbs 1-12 are installed in the lamp body shell, radiator fans 1-7 are installed on the lamp body shell facing the position of bulbs 1-12, radiator fans 1-7 Radiator cover plate 1-4 is arranged on the outside, and connecting bushing 1-10 is installed on the machine head connecting plate 1-14 in the shell, is used for being connected with " U " shape arm 3.

The design of the lamp head part adopts a combination of sealing and rainwater drainage for waterproof design. The structure of the lamp head part is shown in Figure 1. First, install a high-quality rubber ring between the lens 1-3 and the lamp head cover to seal it. When the installation is locked When the lamp cap is covered, the lamp cap tightly presses the rubber ring to achieve a sealed and waterproof effect. At the same time, a waterproof design is carried out on the structure of the lamp cap, and a drain hole 1-1 and a drain groove 1-2 are arranged on the lamp cap, and the drain hole 1-1 is opened on the cylindrical side wall of the lamp cap close to the lens On, communicate with drainage groove 1-2. When the water flow rate is too large and there is water at the lens, the excessive water will flow out along the drainage groove 1-2 through the drainage hole 1-1 of the lamp cover, so as to achieve a good effect of dredging rainwater.

The inventor of the design of the lamp body has adopted the method of water flow dredging to prevent rainwater from splashing into the lamp body. The expression of the internal flow channeling structure. As shown in Figure 2, it can be seen that the left, right and top of the radiator cover 1-4 have water flow diversion walls 1-9. area, and the blocked rainwater will flow out of the shell along the structure of the water flow channeling wall. The effect of the radiator cover plate 1-4 in the structure is to prevent rainwater from directly dripping into the radiator fan 1-7, and the outer surface of its cover plate is shaped into an arc; Water flow diversion walls 1-9 are arranged at the places where the outer edges meet to prevent rainwater from entering the range of radiator cover plates 1-4; when raindrops hit the cover plate, the rainwater can flow away quickly without remaining stagnant water.

As can be seen from Fig. 2, a row of ventilation windows 1-5 are designed on the left and right sides of the radiator cover plate 1-4; The left and right sides of wall 1-11), when the rainwater drips into the exhaust window, it will be directly discharged from the lamp body through the water flow channel. The four water retaining walls 1-11 on the front of the radiator fan in Figure 4 are to prevent the water from flowing directly into the lamp body, and the blocked water will flow out of the lamp body along the water flow channeling grooves on both sides. This triple rainwater channeling structure can completely block the Rainwater flows into the lamp body.

The structure of the radiator cover plate is shown in Figure 3. The ventilation windows on both sides of the radiator fan cover plate 1-4 play the role of air intake and air outlet. The water wall 1-6 is located on the inner side of the radiator. During installation, the water-blocking wall is located on the outside of the water-retaining wall. The two water-blocking walls 1-6 are to prevent water droplets from dripping directly from the exhaust window to the radiator fan, and the cover plate is fixed The method is to match the screw fixing column with the two guide holes of the lamp body shell, and then lock the self-tapping screws in the corresponding holes inside the lamp shell.

The rainwater drainage effect of the lamp body after operation:

To make outdoor lights waterproof, first of all, we must consider the installation method of the occasion and the waterproof of the various travel angles of the light body. It is necessary to take rainproof measures in all directions to ensure the normal operation of the light body. Figure 4 is a diagram of rainwater drainage after one side of the radiator cover is disassembled. The arrows in the figure indicate the direction of water flow formed by raindrops passing through the drainage structure behind the shell. The structure of rainwater drainage can also be clearly seen from the figure. The minimum height of the four waterproof walls at the air outlet of the radiator fan is not less than 7 mm; it can prevent a certain amount of water flow, and the blocked rainwater flows through the rainwater drainage groove structure and finally discharged out of the shell, forming the effect of rainwater drainage.

When the lamp body rotates, rainwater will not flow into the radiator fan, as shown in Figure 5, Figure 6, and Figure 7 are the rainwater drainage diagrams when the lamp body rotates at three angles, and the arrows in the figure indicate the rainwater flow after the lamp body rotates at various angles Direction, according to the arrows in the figure, it can be observed that the flowing rainwater is completely blocked by the four-sided waterproof wall, and then flows to the back row of the rainwater drainage groove and flows out of the lamp body, which makes the radiator part of the lamp body have a multi-angle rainwater drainage effect.

The light bulb will generate strong heat, and this heat will increase the temperature of the lamp body. When the temperature rises to the highest level, if the heat dissipation is not good, the bulb will explode at any time. Figure 9 is a cross-sectional view of the lamp body. After the lamp body is cut open, the structure of the heat dissipation part of the bulb can be clearly expressed. It can be seen that the heat dissipation of the light beam lamp body of the utility model uses two radiator fans 1-7 for heat dissipation, and the symmetrical installation On the shell of the lamp body, one is the air inlet radiator fan, and the other is the exhaust air radiator fan. The arrows in the figure indicate the guide mark of the air inlet and the air outlet. This heat dissipation structure can make the lamp The air circulation in the body reduces the internal temperature, and the effect of the stainless steel shield 1-13 installed between the bulb and the air intake radiator fan is to prevent a small amount of rainwater or other objects entering the radiator fan from directly hitting the bulb and causing the bulb to break. damage.

The heat dissipation fan of the utility model is designed and installed as a wind path, one in and one out. When the wind enters the lamp body and passes through the bulb, the temperature will increase, and the temperature of the wind that is discharged will be higher. If the hot air discharged by "fan 2" is drawn back by "fan 1" to form a hot air circulation, the lamp body cannot achieve a better heat dissipation effect. In order to prevent this problem, we have designed two air-guided tail fins 1-8 at the air outlet of the lamp body shell. The inner arc surface of 1-8 and the air path will change the direction of the air path according to the shape of the arc, so that the hot air will be discharged in the opposite direction of the air inlet after being discharged, (as shown in Figures 8 and 9).

Fig. 10 is the rain-proof structure of the connecting part of the arm and the bearing sleeve. The connecting shaft sleeve 1-10 is connected and sealed with the arm 3 through the shaft sleeve upper cover 4-1, the shaft sleeve lower cover 4-2, and the shaft sleeve upper cover 4-1 and the shaft The sleeve lower cover 4-2 is connected with the connecting buckle 4-3 through the pin shaft 4-5, and the shaft sleeve lower cover 4-2 has a side fixed plate 4-4, which is fixed on the arm 3 through the mounting hole of the fixed plate, and the fixed plate The outer ring of the hole opened on 4-4 is provided with a waterproof wall 4-6, the ring sleeve of the lower cover of the shaft sleeve 4-2 is provided with a water outlet 4-7, and the connecting shaft sleeve is provided with a waterproof wall 4-11 and a waterproof groove 4-10, the side of the shaft sleeve upper cover and the shaft sleeve lower cover close to the lamp head is provided with a rainwater dredging wall 4-8 along the radial flanging, and the connecting shaft sleeve 1- The outer edge of the hole in 10 is provided with a protruding rainwater drainage groove. 4-9 The bushing connection waterproof method uses a plastic bushing to block and guide the water flow. The installation of the bushing is simple and flexible. First, install the lower cover of the bushing on the corresponding Lock the left and right side panels of the arm with countersunk screws (coat a circle of glass glue on the joint), then use the pin shaft to connect the upper cover and the lower cover of the sleeve, and finally fix the pin with a spring card. After installation, the upper cover can be turned over at an angle > 180°, and the lamp body shell can be easily disassembled after turning over the shaft sleeve upper cover. In addition, a sheet metal part is installed at the lock handle of the upper cover of the shaft sleeve, and a rubber sheet is pasted inside the movable hole of the lock handle of the sheet metal part, which can strengthen the strength of the upper cover and prevent water from flowing into the lamp body along the lock handle.

Figure 12 shows the guide structure for side-mounted installation

The two shaft sleeves play the role of blocking rainwater and channeling rainwater. It can be seen from the figure that when raindrops hit the arm shell, the rainwater will flow down; until the raindrops fall behind the lamp body shell and flow away. When rainwater flows into the bushing at the lower end (sleeve 2) along the arc of the lamp body, water accumulation may occur. To solve this problem, as shown in Figure 11, it can be seen that each hole in the shaft sleeve has a waterproof wall, and the function of the waterproof wall is to prevent rainwater from flowing into the arm from the opening. The blocked rainwater will flow out from the drain below, forming a water circulation effect, which is the rainwater drainage structure installed on the side of the arm part. (Note: Figure 12 is a structural diagram of the lamp body cut in half and the hidden part is not related to the waterproof structure. It is mainly to describe its rainwater drainage structure more clearly. The arrow in the figure indicates the flow direction of rainwater through the arm and the shell.)

Horizontal placement of the dredging structure

When the lamp body is placed vertically, the rainwater drips on the surface of the shell to form a water flow, and the rainwater flows down along the outline of the lamp body, and some of the rainwater will flow to the joint between the arm and the lamp body. Figure 13 is a diagram of the rainwater drainage structure at the junction of the lamp body and the arm. In the figure, the upper cover of the sleeve is turned 20° to clearly express the internal rainwater drainage structure.

When the upper and lower covers of the shaft sleeve are assembled, the dredging groove will be partially covered, which can prevent rainwater from directly dripping into the bearing structure. If the rainwater drops on the surface of the lamp body, part of the rainwater will flow to the structure of the dredging groove, and then flow down along the structure of the dredging groove until it is discharged from the lamp body. The structure of the upper cover of the shaft sleeve also has the effect of rainwater drainage. The upper cover is about 2 mm high and the drainage wall can prevent rainwater from flowing to the drainage groove below. The arrow in Figure 13 indicates the flow direction of rainwater droplets after flowing through the drainage groove behind the casing.

Hanging installation and dredging structure

When the lamp body is hung and installed, because the area of the base itself is larger than that of the lamp body, the base will have the effect of blocking rainwater. When the amount of rainwater is too large, the water flow from the base will drip to the surface of the lamp body and then flow along the outline to the Flow away behind the rainwater drainage groove (as shown in Figure 15). If a small amount of water drips into the bearing sleeve through the drain, the "waterproof wall" and "waterproof groove" of the bearing sleeve can prevent rainwater from flowing into the lamp body and guide rainwater, and the inflowing rainwater will flow along the structure of the waterproof groove Flow down; until the drip flows out of the lamp body at the drain, it plays a role in preventing rainwater from flowing to the bearing part and the inside of the lamp body. (as shown in Figure 14)
