Embodiment Construction
[0015] Referring to the accompanying drawings, the structure and functions of the system will be described in detail below.
[0016] Such as figure 1 As shown, the LED lighting device that automatically adjusts the heat dissipation performance includes an ambient illumination sensor 1, a luminous body 2, a heat dissipation device 3 and a controller 4. The luminous body 2 includes a first light source 2-1 and a second light source 2-2. The light source 2-1 is a white LED that emits white light with a color temperature of 4500-5500K, and the second light source 2-2 is a blue LED that emits blue light;
[0017] Such as figure 2 As shown, the heat dissipation device 3 has a plurality of heat dissipation spiral tubes vertically arranged with the luminous body 2, and the heat dissipation spiral tube is an elastic spiral body 3-1 made of a thin metal sheet with good thermal conductivity, one end of which is connected to the luminous body. The body 2 is fixedly connected, and the o...

The invention discloses an LED lighting device capable of automatically adjusting heat dissipating performance, and aims at creating a lighting environment for realizing the best eyes protecting performance. The device comprises an environmental illumination sensor, a lighting body, a heat dissipating device and a controller, wherein the lighting body comprises a first light source and a second light source; the heat dissipating device is provided with different working modes and different heat dissipating capacities; the controller comprises a light adjusting part for adjusting color temperature of irradiating light of the LED lighting device, a storing part for storing light and color adjusting curves used for providing the light adjusting control modes of the light adjusting part, a determining part for determining whether the lighting efficiency of the lighting body is less than a set value, and a performing part for selecting the working mode of the heat dissipating device. According to the device, the illumination and the color temperature of the irradiating light of the LED lighting device can be automatically adjusted so as to create the lighting environment for realizing the best eyes protecting performance; and moreover, the heat dissipating capacity can be automatically adjusted based on the lighting parameters, and thus the service life of the LED lighting device isprolonged.
Description
technical field [0001] The invention belongs to the field of LEDs, in particular to an LED lighting device for automatically adjusting heat dissipation performance. Background technique [0002] LEDs that provide high-intensity lighting with low power are increasingly used in vehicles, and by individually controlling the lighting of multiple LEDs, it is possible to adjust the light distribution and illuminance of the irradiated light. There are various lighting devices in the prior art that can control the output ratio of the light source and can adjust the illuminance and color temperature of the irradiated light. Although this LED lighting device can automatically or intelligently adjust the irradiation light, its heat dissipation device cannot be matched with automation or intelligence. Contents of the invention [0003] In order to solve the above problems, the present invention provides an LED lighting device that automatically adjusts heat dissipation performance to...
