Description

Technical Field

[0001] The present invention relates to the technical field of lighting, and particularly to an industrial lighting lamp. Background Art

[0002] Industrial lighting lamps are specifically designed for harsh industrial environments. With their extremely long service life, excellent lighting effects, outstanding corrosion resistance, and reliable dust-proof performance, they widely illuminate every corner of factories, warehouses, workshops, etc. These lamps are not only powerful but also need to meet the high requirements for high power in various complex scenarios.

[0003] However, high power means high heat. If the lamp is placed in a high-temperature environment for a long time, its light power will gradually weaken, the aging speed of the chip will accelerate, and its working life will be greatly reduced. In addition, the dust accumulated inside the lamp is also a major factor affecting the service life of the lamp.

[0004] To balance the heat dissipation performance and dust-proof performance of the lamp, the existing lamp setting structures mainly install heat dissipation fins on the lamp body and open heat dissipation holes connecting the installation cavity with the outside. The heat on the lamp body is transferred to the air through the heat dissipation fins for heat exchange, and while reducing the temperature, a good dust-proof performance can also be ensured. However, in places with high power or poor air flow, its heat dissipation efficiency will be greatly reduced. In addition, since the lamp body is installed in a sealed installation cavity, it does not form a direct convection interaction with the air, and thus cannot achieve a good heat dissipation effect, thereby affecting the service life and reliability of the lamp. And the method of opening heat dissipation holes will cause dust to directly enter the installation cavity through the heat dissipation holes, thus unable to achieve the dust-proof effect. Based on the above problems, the present invention is born. Summary of the Invention

[0005] The purpose of the present invention is to provide an industrial lighting lamp that can balance good dust-proof performance and heat dissipation performance, so as to improve the reliability and service life of the lamp.

[0006] The above technical purpose of the present invention is achieved through the following technical solutions: An industrial lighting lamp includes a lamp base, an installation cavity formed in the lamp base, and a lamp body installed in the installation cavity. A heat generation area is formed at a position on the back of the lamp body in the installation cavity. A ventilation structure for accelerating the air flow velocity is provided in the lamp base in cooperation with the heat generation area. The ventilation structure includes an acceleration air duct. A communication port communicating with the heat generation area is provided on the acceleration air duct. Both the air inlet and the air outlet of the acceleration air duct communicate with the outside. A guiding structure for guiding the air flow to flow through the communication port is provided in the acceleration air duct.

[0007] By adopting the above technical solution, a high-power lamp body will generate a large amount of heat during operation, and the heat generated by the lamp body is concentrated at the heat generation area on the back of the lamp body and heats the air above and around the heat generation area to form an upward heat flow. After the heat flow rises, a negative pressure area will be formed at its bottom, thereby sucking the air in the outside world through the air inlet into the acceleration air duct and extracting the heat in the heat generation area. The hot air accumulated at the top of the acceleration air duct forms a positive pressure area, which can then more quickly push the gas out through the air outlet. Through this set structure, the gas passing through the acceleration air duct can be accelerated, and the air flow passing through the acceleration air duct extracts the heat accumulated in the installation cavity through the communication port, thereby achieving a better heat dissipation effect. And because this set structure will form a negative pressure that sucks outwards in the installation cavity, combined with the set guiding structure to guide the air flow to flow through the communication port, it can prevent the dust passing through the acceleration air duct from entering the installation cavity through the communication port. This set structure can achieve direct communication between the outside world and the installation cavity, and on the premise of having good heat dissipation performance, it can also take into account good dust-proof performance, thereby improving the reliability and service life of the lamp.

[0008] It is further set that: the acceleration air duct includes an air inlet passage with the air inlet and an air outlet passage with the air outlet, the communication port is located at the intersection of the air inlet passage and the air outlet passage, the air inlet is located on one side of the communication port in the vertical direction, the air outlet passage includes a first air outlet section connecting the communication port, and the first air outlet section is located directly above the communication port and is vertically arranged.

[0009] By adopting the above technical solution, this set structure directly connects the air inlet passage with the negative pressure area formed by the heat flow, and can more quickly and smoothly suck the air into the air inlet passage through the air inlet; and the vertically arranged first air outlet section is more conducive to the accelerated upward movement of the hot air, thereby increasing the speed of the air when passing through the acceleration air duct.

[0010] It is further set that: the air outlet passage further includes a third air outlet section with the air outlet, the third air outlet section is vertically arranged and the air outlet is arranged upwards, and the positive projection path of the air outlet along the axis of the third air outlet section does not communicate with the communication port.

[0011] By adopting the above technical solution, the vertically arranged third air outlet section is more conducive to the discharge of air, and by making the positive projection path of the air outlet along the axis of the third air outlet section not communicate with the communication port, it can prevent dust from entering the communication port through the air outlet, so as to achieve a better dust-proof effect.

[0012] Further configured as: the air outlet channel further includes a vertically arranged second air outlet section, the first air outlet section and the second air outlet section are connected by a first connecting section, and the second air outlet section and the third air outlet section are connected by a second connecting section. The second connecting section is arranged at a position close to the heating area and is heated by the heating area, and the first connecting section is arranged at a position far from the heating area.

[0013] By adopting the above technical solution, the air flow is sequentially transmitted along the first air outlet section, the first connecting section, the second air outlet section, the second connecting section and the third air outlet section. When the air flow is transmitted to the first connecting section, since the first connecting section is far from the heating area, a low-temperature area will be formed at this position, and the air pressure in the low-temperature area is high; when the air flow is transmitted to the second connecting section, since the second connecting section is close to the heating area, a high-temperature area will be formed at this position, and the air pressure in the high-temperature area is low. The pressure difference formed in this way can better draw the air flow to flow, generate a greater suction force to increase the flow rate of the air flow, and then more efficiently take away the heat, so as to achieve a better heat dissipation purpose.

[0014] Further configured as: the guiding structure is a limiting guiding block arranged in the air inlet channel and close to the communication port. The limiting guiding block is arranged at a position on the air inlet channel wall close to the installation cavity. The side of the limiting guiding block facing away from the installation cavity is gradually inclined along the direction from the air inlet to the communication port and forms a guiding inclined surface.

[0015] By adopting the above technical solution, the limiting guiding block and the guiding inclined surface can better guide the air flow through the communication port, reduce the probability of dust in the air flow entering the installation cavity through the communication port, and thus achieve a better dust-proof effect.

[0016] Further configured as: a dust-proof cover is provided above the air outlet, the orthographic projection path of the air outlet intersects the dust-proof cover, and a ventilation gap is formed between the air outlet and the dust-proof cover.

[0017] By adopting the above technical solution, the provided dust-proof cover can further reduce the probability of dust entering the air outlet, achieve a better dust-proof effect while better ensuring the smoothness of the air outlet channel; and the formed ventilation gap enables this setting structure not to interfere with the normal discharge of the air flow.

[0018] Further configured as: the lamp body and the acceleration air duct are both arranged in a ring around the center of the lamp base, and the lamp base is provided with a heat dissipation channel penetrating along the axis of the lamp base at the position of the inner circle of the lamp body.

[0019] By adopting the above technical solution, the setting of the heat dissipation channel improves the air flow passability around the lamp, so as to improve the heat dissipation effect.

[0020] Further configured as: the lamp holder includes a first main body part and a second main body part, a fixing structure for assembling and fixing the two is provided between the first main body part and the second main body part, and the first main body part and the second main body part are assembled to form the acceleration air duct.

[0021] By adopting the above technical solution, by respectively processing the structures for forming the acceleration air duct on the first main body part and the second main body part, and then splicing the first main body part and the second main body part, the complete acceleration air duct structure can be formed, thereby reducing the processing difficulty and production cost.

[0022] Further configured as: the fixing structure is a plurality of bolts passing through the first main body part and threadedly connected to the second main body part.

[0023] By adopting the above technical solution, the bolts are used to fix the first main body part and the second main body part.

[0024] Further configured as: a radiator connecting the lamp body is provided at a position corresponding to the heating area in the installation cavity.

[0025] By adopting the above technical solution, the setting of the radiator can better guide the heat on the lamp body to be concentrated and conducted to the heating area position, and can form a more concentrated high-temperature area at the heating area position, thereby increasing the temperature difference, increasing the thermal pressure effect, and better improving the flow rate of the air flow.

[0026] In summary, the present invention has the following beneficial effects: the present invention can take into account good dust-proof performance and heat dissipation performance, thereby improving the reliability and service life of the lamp. BRIEF DESCRIPTION OF THE DRAWINGS
