Background
A light Emitting diode (led), which is a solid semiconductor device capable of converting electrical energy into visible light, can directly convert electricity into light. The heart of the LED is a semiconductor wafer, one end of the wafer is attached to a support, the other end of the wafer is a cathode, and the other end of the wafer is connected with an anode of a power supply, so that the whole wafer is packaged by epoxy resin. The semiconductor wafer is composed of two parts, one of which is a P-type semiconductor in which holes predominate and the other of which is an N-type semiconductor in which electrons predominate. When the two semiconductors are connected, a P-N junction is formed between them. When current is applied to the wafer through the wire, electrons are pushed to the P region where they recombine with holes and then emit energy in the form of photons, which is the principle of LED lamp illumination. When the LED table lamp is used, the gear of the conventional table lamp is fixed, the correspondingly generated luminous flux is also fixed, the illumination of a use area is the superposition of the illumination of a light source of the table lamp and the illumination of ambient light, the illumination of the table lamp is kept unchanged, but the external ambient light has no influence on the use of a user after the angle and the aspect are adjusted when the LED table lamp is used. However, if the ambient light changes greatly, working or learning in this environment will make users easily have fatigue, and the requirements of people in modern society for LED lamps cannot be met.
In order to solve the technical problem, the utility model discloses a can respond to external luminance automatically regulated desk lamp luminance's eyeshield desk lamp, the lamp holder upper cover and the lamp holder lower cover of this eyeshield desk lamp that can respond to external luminance automatically regulated desk lamp luminance are whole to be circular, be equipped with a plurality of LED lamp pearls in the lamp holder upper cover, be equipped with the even worn-out fur of annular in the lamp holder lower cover, be equipped with the light-passing board mounting hole on the lamp base, install the light-passing board in the light-passing board mounting hole, the below of light-passing board is equipped with the sensitization board in proper order in the lamp base, the photometry chip, photo resistance. The light-passing board can pass through the photosensory board with the outside light of desk lamp, it detects the light change on the photosensory board to survey the light chip, give photo resistance with signal transmission, the control panel can adjust the luminance of LED lamp pearl according to photo resistance's signal, from the influence that the change of offsetting ambient light LED to the fact the user, avoided bringing visual fatigue for the user, be fit for using widely.
