Abstract
The utility model discloses a table lamp capable of automatically changing color temperature, which comprises a base, a light-emitting body and a lamp shade and is characterized in that a temperature sensor module and a control circuit are arranged on the base. The light-emitting body comprises a warm-color light-emitting diode (LED) lamp bead and a cold-color LED lamp bead. The control circuit is connected with the temperature sensor module and the light-emitting body through wires. The table lamp can give out warm-color light when the temperature is lower than a preset temperature and give out cold-color light when the temperature is higher than a preset temperature, thereby enabling people to feel that the light environment is very comfortable. A light-scattering board is performed with anti-glare treatment so that light is gentle and eyes of users can be protected. The table lamp is provided with a light adjustor and capable of adjusting the intensity of light so that the users feel more comfortable when the table lamp is used in different illumination degrees.
Description
Technical field
The utility model relates to a kind of light fixture, in particular a kind of desk lamp that changes Light Color that changes through temperature sensor.
Background technology
At present, the desk lamp of tunable optical is used very extensively in life now, and it can adjust the brightness of light; But still there are a lot of deficiencies in this lamp dimmer: can only change the power of light, but can not change the colour temperature of desk lamp, the desk lamp of the warm light of usefulness; Summer, just sensation was very hot; Very uncomfortable, also can let people uncomfortable with regard to special cold desk lamp winter of cold light.
Chinese patent Granted publication number: CN 201518554 U; June 30 2010 Granted publication day; Name is called dimmable energy-saving lamp, and an end of power supply input is provided with a fuse, and the power supply two-stage parallel connection has Interference Control circuit and rectifier bridge; The other two ends of rectifier bridge are connected with power factor correction circuit with the harmonic wave control section respectively; The harmonic wave control section is electrically connected with the other end of power factor correction circuit, and the circuit of power factor correction two ends are parallel with current foldback circuit, and the current foldback circuit two ends are connected with the trigger two ends; Between current foldback circuit two ends and trigger, be connected with a bidirectional trigger diode: the trigger two ends are connected with regenerator section, and regenerator section is connected with fluorescent tube.This light modulating energy-saving lamp can only change the light power, can not change the color of light, if when wanting to change the color of indoor light, can only change light source, and is so very inconvenient.
The utility model content
The utility model has overcome the prior art desk lamp can not Along with season change the deficiency that changes the light colour temperature, and providing a kind of can Along with season change the desk lamp that changes the light colour temperature.
To achieve these goals; The utility model adopts following technical scheme: a kind of desk lamp of colour temperature capable of automatic changing; Comprise base, illuminator, lampshade; Base is provided with temperature sensor module and control circuit, and illuminator comprises the LED lamp pearl of warm colour LED lamp pearl and cool colour, and control circuit is connected with temperature sensor module, illuminator electric wire.Temperature sensor module on the Desk lamp feet is passed to control circuit to temperature signal, and control circuit is lighted according to temperature signal control warm colour LED lamp pearl or cool colour LED lamp pearl.Make desk lamp can when temperature is high, send the light of cool colour, give the refrigerant sensation of people, send the light of warm colour when temperature is low, give the warm sensation of people.
As preferably, the lampshade openend of desk lamp is provided with astigmatism plate, prevents that dust etc. is adsorbed onto LED lamp bead surface and causes luminance shortage.
As preferably, astigmatism plate is the anti-dazzle tabula rasa of frosted, and the light of LED lamp is assembled very much, and the astigmatism plate frosted can let divergence of beam, protection user's eyes.
As preferably, on the base of desk lamp, be provided with dimmer switch, desk lamp can be adjusted the power of light, can satisfy the use in the different lightness environment.
Therefore, the utlity model has following beneficial effect:
(1) desk lamp can send the light of warm colour when temperature is lower than design temperature, sends the light of cool colour when temperature is higher than design temperature, lets the people feel that light environment is very comfortable;
(2) astigmatism plate is done anti-dazzle and is handled, and can let soft that light becomes, protection user's eyes;
(3) desk lamp is provided with light modulator, and it is strong and weak to let desk lamp regulate light, can in difference degree of illuminating, use more comfortable.
Description of drawings
Fig. 1 is the real structural representation of the utility model.
Among the figure 1, face shield 2, astigmatism plate 3, temperature sensor module.
The specific embodiment
Below in conjunction with the accompanying drawing and the specific embodiment the utility model is done further description
The desk lamp of colour temperature capable of automatic changing as shown in Figure 1; Comprise base, illuminator, lampshade 1; Base is provided with temperature sensor module 2 and control circuit, and illuminator comprises the LED lamp pearl of warm colour LED lamp pearl and cool colour, and control circuit is connected with temperature sensor module, illuminator electric wire.The lampshade openend is provided with astigmatism plate 3, and astigmatism plate is a frosted PMMA plate.Base is provided with dimmer switch branch third gear, be respectively strong, in, a little less than.Surrounding environment.When temperature was lower than design temperature, temperature sensor module was passed to control circuit to signal, and control circuit control warm colour LED lamp pearl sends warm light; When temperature was higher than design temperature, control circuit control cool colour LED lamp pearl sent cold light.When room brilliancy is not enough, get to strong these shelves to dimmer switch, make desk lamp send high-high brightness; When room brilliancy is big, get to weak these shelves to dimmer switch, desk lamp is sent than low-light level.
Claims (4)
