Description

Infrared sensor light

technical field

The utility model relates to an induction lamp, in particular to an infrared induction lamp which uses the principle of infrared induction to judge whether someone passes by, and determines whether to turn on according to the brightness of the environment.

Background technique

In many places that need lighting, such as corridors, garages, etc., sensor lights that use voice control to determine whether to turn on are often installed. There are certain problems with this type of induction lamp: first, traditional induction lamps mostly use incandescent lamps, which wastes electric energy; When the noise exceeds 55 decibels, the induction light will also light up, which will also waste electricity. Therefore need a kind of novel induction lamp that can solve above-mentioned problem now.

Contents of the invention

The utility model aims to solve the above-mentioned deficiencies in the prior art, and proposes a simple structure, ingenious design, reasonable layout, which can determine whether to work according to the brightness of the surrounding environment, and uses infrared sensing to judge whether there are people passing by. Infrared sensor light.

The technical solution of the utility model is: an infrared induction lamp, including a housing 1, characterized in that: the housing 1 is provided with an LED lamp bead 2, and the LED lamp bead 2 is located Inside the lampshade 3, a Fresnel lens 4 is arranged at the geometric center of the lampshade 3, and a pyroelectric infrared sensor 5 and a photoresistor are arranged inside the Fresnel lens 4.

There are four LED lamp beads 2 , which are evenly distributed on the housing 1 .

Compared with the prior art, the utility model has the following advantages:

This kind of infrared induction lamp has a simple structure and ingenious design. Aiming at the shortcomings of the traditional induction lamp using voice control, it designs a special structure that uses the principle of infrared induction to judge whether there is a person passing through. Installed with a photoresistor, it can judge whether it needs to be turned on according to the brightness of the environment. It can avoid the defect that the traditional voice-activated sensor light will also turn on when there is noise. It has the advantages of flexibility and convenience, and can save a lot of power. Therefore, it can be said that This infrared induction lamp has multiple advantages, is particularly suitable for popularization and application in this field, and has a very broad market prospect.

Description of drawings

Fig. 1 is a schematic structural view of an embodiment of the utility model.

Detailed ways

The specific embodiment of the utility model will be described below in conjunction with the accompanying drawings. As shown in Figure 1 and Figure 2: an infrared induction lamp, including a shell 1 as a base, four LED lamp beads 2 are arranged on the outer surface of the shell 1, and these four LED lamp beads are evenly distributed On the housing 1, a lampshade 3 is arranged outside the LED lamp bead 2. The lampshade 3 is fixedly fastened on the housing 1. A Fresnel lens 4 is arranged at the geometric center of the lampshade 3. Inside the Fresnel lens 4 A pyroelectric infrared sensor 5 and a photoresistor are provided.

The working process of the infrared induction lamp in the embodiment of the utility model is as follows: install the induction lamp in places such as corridors, corridors, garages, etc., when the photoresistor detects that the brightness of the surrounding environment is good and does not need to provide lighting, even if someone passes by , the device will not work;

When the photoresistor detects that the brightness of the surrounding environment is poor and additional lighting needs to be provided, if someone passes by, the pyroelectric infrared sensor 5 arranged in the Fresnel lens 4 will work, and control the work of the LED lamp bead 2 to provide environmental protection. illumination.

Claims (2)
