Description

Lamp body, lamp and lamp body heat dissipation method
Technical Field
The invention relates to the field of lighting devices, in particular to a lamp body with high heat dissipation efficiency and water resistance, a lamp and a heat dissipation method of the lamp body.
Background
At present, the internal heat of the lamp body of the LED waterproof lamp in the market is mainly cooled down in a heat conduction and heat radiation mode, and the following situations exist:
(1) The heat of the light source is radiated outside the lamp body through the heat radiation of the lamp body shell. Because the LED module needs to work for a long time, the heat generated by the high-power light source is more and the lamp body is airtight, the heat can not be effectively taken away only by virtue of the radiation heat dissipation of the lamp body shell, and the unstable or failure of an electric element is caused by the overhigh temperature in the lamp body. Therefore, the radiation heat dissipation mode through the lamp body shell can not meet the working requirements of the LED waterproof lamp.
(2) The heat of the light source is conducted and radiated outside the lamp body through the metal radiator, such as a heat pipe radiator, a section radiator and the like. Because the light source has the characteristics of high power, small volume, concentrated heat and long working time, the small volume of the light source limits the joint area of the metal radiator and the light source, the arrangement position of the cavity reserved for the heat pipe or the fins is limited, and the heat exchange efficiency factor of the self structure of the radiator causes low heat exchange efficiency and cannot effectively take away the heat of the light source, and the accumulated heat under long-time working can shorten the service life of the light source or burn the light source.
For example, when the power of the LED module of the heat pipe radiator or the profile radiator is more than or equal to 1200W, the electric element is unstable due to the rapidly increased temperature in a short time, and the temperature of the lamp body cannot be timely and effectively reduced; the radiator is large in size and heavy in weight, so that the whole lamp structure cannot be reduced in size, and a rotating shaft assembly for connecting the lamp body and the lamp arm, the lamp arm and the like also need to be redesigned to adaptively improve rigidity and strength, and related parts cannot be used interchangeably with parts of the non-waterproof lamp, so that the die sinking cost is increased. Especially, the section radiator has the advantages that as the fins are in contact with air, the heat exchange area is larger, the occupied space is larger, the mass is heavier, and in addition, the fins are required to surround the periphery of the light source to conduct heat better, so that more heat can be dissipated into the lamp body of the waterproof lamp through the fins, and the heat of the light source cannot be rapidly and effectively dissipated out of the lamp body. In addition, the cost of a single light source can reach thousands of yuan, and the economic loss is serious due to the excessively high loss rate.

2. Owing to the compact, light and handy lamp body structure and high heat dissipation efficiency, the lamp body, the lamp arm and the lamp holder do not need to enlarge the volume additionally or increase the weight, and the lamp arm, the rotating shaft assembly connecting the lamp arm and the lamp body do not need to correspondingly improve the bearing capacity, the rigidity and the strength to maintain the stability, so that the lamp has compact and handy structure.
