In order to achieve the above object, the technical scheme adopted by the utility model is as follows: an automatic lighting lamp for a freezer, including a base connected to a power cord, a control circuit board, a light-transmitting lampshade and several LED lamps fixedly arranged on the control circuit board , and also includes a reflector arranged between the control circuit board and the light-transmitting lampshade, the reflector is provided with several light-gathering parts for gathering the light of the LED lamp.

Preferably, the light concentrating part is a tapered groove with a through hole at the bottom, and the end of the LED lamp far away from the control circuit board is arranged in the tapered groove through the through hole and through the reflector.

Preferably, the reflector is provided with a mounting hole, and the control circuit board is also provided with an infrared sensing device penetrating through the mounting hole.

Preferably, the reflector is also provided with a mounting groove for assembling and fixing.

Preferably, a plurality of support columns are provided on the end surface of the reflector facing the base.

Compared with the prior art, the beneficial effect of the utility model is: when the lighting lamp is turned on and used, the light scattered by the LED lamp from the surroundings will be reflected and gathered by the light-gathering part on the reflector, so that the lighting lamp can be gathered. The light of the lighting lamp can be brighter in the range of action.

Detailed ways

Referring to Fig. 1 to Fig. 6, the embodiment of the automatic lighting lamp for the freezer of the present invention will be further described.

An automatic lighting lamp for a freezing room, comprising a base 2 connected to a power cord 1, a control circuit board 3, a light-transmitting lampshade 4, and several LED lamps 31 fixedly arranged on the control circuit board 3, and also including a lamp set on the control circuit board 3 and the reflector 5 between the light-transmitting lampshade 4, the reflector 5 is provided with several light concentrating parts 51 for concentrating the light of the LED lamp 31. When the illuminating lamp is turned on and used, the light scattered by the LED lamp 31 from the surroundings will be reflected and gathered by the light-gathering portion 51 on the reflector, so that the light of the illuminating lamp can be brighter in the range of action.

The light collecting part 51 is a tapered groove 511 with a through hole 512 at the bottom, and the end of the LED lamp 31 away from the control circuit board 3 penetrates the reflector 5 through the through hole 512 and is set in the tapered groove 511 . The bottom of its concentrating part 51 is provided with the tapered groove 511 that is used to install LED lamp 31, and on the inner wall of tapered groove 511, all are smooth reflective mirrors 5 surfaces, so just be helpful for the light that LED lamp 31 emits. The light is projected forward, focusing the light, thus making the panel lighting brighter.

Moreover, a through hole 512 for installing the LED lamp 31 is also provided at the bottom of the tapered groove 511, so that the function of the through hole 512 can facilitate the LED lamp 31 to protrude from the bottom of the tapered groove 511, and facilitate the installation of the LED lamp 31. And after the reflection mirror and the control circuit board 3 are installed, the reflection mirror can be connected with the control circuit board 3 through the effect of the through hole 512 where the LED lamp 31 is installed, so that the reflection mirror and the control circuit board 3 are connected and installed It is more reliable, so that when the lighting lamp is in use, the light emitted by it is more stable.

The reflector 5 is provided with a mounting hole 52 , and the control circuit board 3 is also provided with an infrared sensing device 32 passing through the mounting hole 52 . The function of automatic control of the lighting lamp can be realized by the function of the infrared sensing device 32. Just can sensitively sense the temperature difference between the temperature of people's body and ambient temperature, will give control circuit board 3 a control signal like this, control LED lamp 31 to open by control circuit board 3 again, play lighting effect. There is no need to manually turn on the illuminating lamp, which greatly facilitates people's operation and use.

The reflector 5 is also provided with a mounting groove 53 for assembling and fixing. Moreover, the side wall of the reflector is also provided with mounting grooves 53, and there are 3 mounting grooves 53, which are evenly distributed on the reflector, which is conducive to the installation of the reflector and the assembly and production of the whole reflective taillight, greatly improving the performance of the reflector. Productivity for reflective taillights.

A plurality of support columns 54 are provided on the end surface of the reflector 5 facing the base 2 . The function of the support column 54 is to support the reflector 5 after the assembly and production of the lighting lamp is completed, so that a certain gap can be formed between the reflector 5 and the control circuit board 3, thereby preventing the reflector 5 from contacting the control circuit board. 3 generates friction, which can safely and effectively protect the mirror 5 and the control circuit board 3.

The above descriptions are only preferred implementations of the present utility model, and the protection scope of the present utility model is not limited to the above-mentioned embodiments, and all technical solutions under the idea of the present utility model all belong to the protection scope of the present utility model. It should be pointed out that for those skilled in the art, some improvements and modifications without departing from the principle of the utility model should also be regarded as the protection scope of the utility model.
