Embodiment Construction

[0022] The present invention will be further described below with reference to the accompanying drawings.

[0023] Such as Figure 1 to Figure 2 As shown, this embodiment includes a lens 1, a light source substrate 2, a radiator 3 and a housing 4, the lens 1 is connected to the light source substrate 2, the light source substrate 2 is connected to the radiator 3, and the other side of the radiator 3 is connected to the casing 4 connection, wherein the light source substrate 2 adopts an aluminum substrate, and the light source adopts a single low-power light source array arrangement design. The interior of the housing 4 is hollow to form an air flow passage for the hot air to flow from bottom to top. Cooperate to form the connecting air duct section 401 that passes through the cold air flow to dissipate heat, the airflow accelerating section 402 that is arranged at the front end of the connecting air duct section 401 along the rising direction of the hot air flow, and the airf...

Abstract

The invention provides a passive type fan structure lamp. The inner part of a shell forms an air flow channel; the shell comprises a connection air channel section which is arranged at the end part, which is used for generating hot air flow, on a heat dissipation body, an air flow acceleration section which is arranged at the front end of the connection air channel section along the hot air flow rising direction and an air flow outlet formed in the front end of the air flow acceleration section along the hot air flow acceleration flowing direction, wherein a heat dissipation fan which rotates under the unidirectional flowing action of hot air flow to enhance the heat dissipation effect is arranged in the air flow outlet. By the design of the shell appearance, the flowing-out speed of air flow generated by heat dissipation is increased; meanwhile, the heat dissipation effect is enhanced by driving the fan to rotate by the air flow.

Description

technical field [0001] The invention relates to the technical field of LED lamps, in particular to a passive fan structure lamp. Background technique [0002] LED lamps use LED chips as the main body of the light source, but the junction temperature of the LED chip can greatly affect its light efficiency when it is working, so the heat dissipation design of LED lamps is very important. This method dissipates heat, and this method will affect the heat dissipation effect because the hot air flow cannot be taken away in time in an environment where the air flow is not severe. Therefore, it is necessary to design a lamp that can actively generate cold and hot air flow to increase the heat dissipation effect. [0003] Another example is a utility model patent, No. CN202915139U discloses a fan-type LED lamp, which includes a cylinder, a radiator, an LED lamp, a reflector cup and a fan; There are reflective cups and LED lights, and a mounting seat is fixed on one side of the radia...
