Problems solved by technology

[0003] LED light sources are used in various lighting equipments due to their long life, high luminous efficiency, no radiation, and low power consumption. Use a current limiting resistor, or directly connect to the power supply, and there is no light-emitting diode intensity adjustment circuit. This form of circuit will cause the LED light-emitting diode to age prematurely, greatly shorten the service life, and limit the use of the occasion.

Embodiment Construction

[0021] As shown in Figure 2, the functional block diagram of the internal electronic control circuit of the LED lamp of the present invention, after the main circuit is connected to 220V alternating current, through C 0 Buck, R 0 current limiting, bridge rectifier 4 rectifier and C 1 After filtering, the alternating current is converted into direct current, and the main circuit is divided into three supply circuits: battery charging control circuit, strong light, weak light control circuit and function control circuit. There is also a resistor R in the main circuit 1 , C 1 × R 1 The time constant determines the extended time for the emergency lights to turn on after a power failure. The terminals of the three supply circuits are respectively connected to the LED light-emitting diode current stabilization circuit, and then the LED light-emitting diode current stabilization circuit is connected to and controls the combination of LED light-emitting diodes, and the function con...

Abstract

The invention discloses an LED lamp, which comprises an upper plastic component, wherein the top of the upper plastic component is sleeved with a lamp cap connected with a power supply; the bottom of the upper plastic component is connected with a lower plastic component; the inside of the lower plastic component is provided with a plurality of light emitting diodes in an array; the inside of theupper plastic component is also provided with an electronic control circuit board which comprises a circuit board body and an electronic control circuit; and the electronic control circuit is connected with the light emitting diodes electrically. The electronic control circuit of the LED lamp is provided with a current stabilizing circuit and a strong and weak light control circuit of the light emitting diodes additionally, so electrical energy is saved and the service lives of a battery and the light emitting diodes are prolonged. The shells of components of the invention are two-piece structures made of flame-retardant plastic materials, so the LED lamp has light overall weight, small volume and convenient carrying.

Description

technical field [0001] The invention relates to a lighting appliance, in particular to an LED lamp. Background technique [0002] The general lighting, emergency lighting and flashlights currently on the market each have lighting functions, but they are heavy and bulky. The biggest disadvantage is that they have a single function. In some occasions, you need to bring a variety of lighting equipment in case for need. [0003] LED light sources are used in various lighting equipments due to their long life, high luminous efficiency, no radiation, and low power consumption. Using a current limiting resistor, or directly connected to the power supply, and without a light-emitting diode intensity adjustment circuit, this form of circuit will cause the LED light-emitting diode to age prematurely, greatly shorten the service life, and limit the use of the occasion. Contents of the invention [0004] The problem to be solved by the present invention is to provide a multi-functio...
