Problems solved by technology

[0004] However, due to the limitation of the location of the light sensor, it may not be able to accurately reflect the color temperature of the lighting light excited by the phosphor powder of the LED luminous grain, or the color temperature of the mixed light in the LED lamp.
[0005] It can be seen that the above-mentioned existing LED lamps obviously still have inconvenience and defects in structure and use, and need to be further improved urgently.

Abstract

The invention relates to a lamp which comprises a shell, a plate body, a light emitting module and a photosensor; the plate body is arranged in the shell and is provided with a wavelength conversion material; the light emitting module and the plate body are arranged in the shell at intervals; and the light emitting module further comprises a circuit board and a plurality of lighting units arranged on the circuit board and irradiating towards the plate body. The photosensor is arranged on the plate body and is used for sensing the color temperature of light rays emitted from the lighting units and passing through the plate body and the wavelength conversion material.

Description

technical field [0001] The present invention relates to a lamp, in particular to an LED (Light Emitting Diode, light emitting diode) lamp with a light sensor. Background technique [0002] Due to the advantages of power saving, long service life and environmental protection, LEDs have been gradually applied in general lighting fields. [0003] At present, most of the LED lamps are in the form of LED light-emitting grains mixed with phosphor powder to excite and mix light as illumination light. In order to provide stable lighting light, some LED lamps can be equipped with a light sensor (Light Sensor), which is used to sense the color temperature or brightness of the LED lamp, and provide stable color temperature or brightness by controlling the current or voltage. of lighting light. [0004] However, due to the limitation of the position of the light sensor, it may not be able to accurately reflect the color temperature of the lighting light excited by the phosphor powder ...
