[0021] Y 4-x-y Lu x Fe y o 6 The preparation method is as follows:

[0022] Step a) Weighing corresponding weights of diyttrium trioxide, lutetium trioxide and ferric oxide in proportion, grinding them for 1 to 2 hours to obtain micron-sized powder, and fully mixing;

[0023] Step b) Preheating at 400°C for 1 hour, followed by burning at 900°C for 2 hours in a nitrogen / hydrogen (v / v: 98% / 2%) atmosphere to obtain a sintered product;

[0024] Step c) after natural cooling, the sintered product obtained by ball milling until its particle size is 100-110nm;

[0025] Step d) washing with deionized water for 3 times, followed by drying to obtain nanoscale Y 4-x-y Lu x Fe y o 6 .

[0026] Y 4-x-y Lu x Fe y o 6 It can increase the sensitivity of the photosensitive material to visible light, that is, it can make the photosensitive material change the resistance value rapidly when the visible light changes. while in Y 4-x-y Lu x Fe y o 6 , the range of x and y will det...

Abstract

The invention discloses a light sensitive energy-saving street lamp. A sensor is arranged at the top of the street lamp and can control on and off the street lamp according to the intensity of visible light, a light sensitive resistor is arranged in the sensor and comprises an upper electrode layer, a lower electrode layer and a middle light sensitive material layer, and the light sensitive material layer comprises gallium sulfide, cadmium sulfide, zinc sulfide, copper sulfide, beryllium sulfide, strontium sulfide, germanium oxide, niobium oxide, hafnium, iridium and Y4-x-yLuxFeyO6. A light sensitive material is low in manufacturing cost, resistant to ageing, wide in application field and beneficial to large-scale popularization and application, has excellent weather resistance and corrosion resistance and has strong compatibility with the sensor, the light sensitive energy-saving street lamp can automatically sense the visible light, can be automatically turned on and turned off according to the intensity of the visible light and conforms to the advocated trend of energy conservation and environmental protection, and resources are reasonably distributed and used.

Description

technical field [0001] The invention relates to a street lamp, in particular to a light-sensing energy-saving street lamp that can be automatically switched on and off according to the intensity of visible light. Background technique [0002] Street lamp is a very common outdoor lighting tool in people's life. Its existence is not only pole-type street lamps on both sides of the horse, but also includes ground lamps on the grass and landscape lights on tall buildings, all of which belong to street lamps. category. People can see street lights almost everywhere every day. Careful people will find that the opening and closing of street lights are set by human programs, that is, when the opening time and closing time are set, the street lights will be turned on or off at the corresponding fixed time. closure. However, there are disadvantages in this method, that is, in summer when the sunshine time is long, it is easy to appear that the sky is not dark but the street lights a...
