Eye-protection lamp

Abstract

The invention discloses an eye-protection lamp. The eye-protection lamp comprises a light source, a driving device for driving the light source, a master control device for controlling the driving device and a light sensing device for sensing the luminosity and sending a luminosity signal to the master control device. The light sensing device is configured to sense the luminosity of a reading region. Due to the fact that the light sensing device is configured to sense the luminosity of the reading region, the intensity information on reflecting light on books / periodicals / documents located in the reading region can be detected directly; with the information as a reference, the luminosity of light emitted by the light source is adjusted through the master control device and the driving device of the light source, and the luminosity of the light which is on the books / publications / documents and reflected into the eyes is precisely controlled. In this way, the eye-protection lamp can be called the real eye-protection full-automatic dimming reading lamp and has the excellent eye protection effect; the light source is always controlled at the most suitable luminosity; and the luminosity of the light emitted by the light-emitting light source is just right, no excess light is emitted, namely no excess energy is wasted, and the eye-protection lamp has the energy-saving performance and environment-protection performance while the eye protection function is achieved.

Description

technical field [0001] The invention relates to the technical field of lamps, in particular to lamps with eye protection function. Background technique [0002] As for most of the automatic dimming desk lamps on the market, there are nothing more than two methods: [0003] (1) Use a photosensitive device to detect the background light source and then perform a series of calculations to adjust the light source. For example, the photosensitive device is installed on the lamp holder of the desk lamp, which senses the luminosity of the non-reading area, and the sensing direction of the photosensitive element is opposite to that of the desk lamp light source. [0004] Disadvantages of this approach: [0005] Let's not discuss whether its dimming performance and calculation are accurate. Just consider the reliability of its light metering / light control, assuming that this kind of desk lamp is currently locking a certain luminosity on its light source, and the user is reading un...

Problems solved by technology

[0012] The detection methods of the above (I) and (II) two types of automatic dimming table lamps are indirect, the calculation and light control methods are not accurate, the error rate of light detection and light control is high, and the excellent eye protection effect cannot be achieved.
