Light-emitting circuit board based on surface-mounted LED devices

Abstract

The embodiment of the invention discloses a luminous circuit board of an LED (Light Emitting Diode) device based on surface mounting. The luminous circuit board comprises a circuit board base layer, a conducting layer arranged on the circuit board basic layer and finish coat covering on the conducting layer. The LED device comprises an insulated frame body, a positive wafer and a negative wafer, wherein the frame body is internally provided with a polarity dividing strip which is used for dividing the frame body into a hollow positive region and a hollow negative region, and the positive wafer and the negative wafer are respectively arranged at the bottoms of the positive region and the negative region; the positive wafer and the negative wafer are electrically connected with the conducting layer; and an inner inclined wall is arranged between the upper frame surface and the lower frame surface of the frame body. The inner wall of a frame is changed into the inner inclined wall so that the light sources of LEDs are effectively reflected out, the thickness of the frame is reduced, the exposure area of an LED chip is increased, the luminous efficiency of a manufactured LED lamp is greatly improved, light rays are reflected out under the effect of the fitting finish coat and light transmittance coat, and color temperature is increased.

Description

technical field [0001] The invention relates to an LED lighting circuit board structure, in particular to a light-emitting circuit board based on surface-mounted LED devices. Background technique [0002] Because LED lights have the advantages of small size, low power consumption, long service life, high brightness, low heat, environmental protection, and durability, LED lights are becoming more and more popular. The LED can convert electricity into light. Its structure is to place LED chips on a bracket, connect the positive and negative poles of the power supply through the bracket, and package the entire LED with a light-transmitting sheet made of epoxy resin fingers. Problem: Due to the certain resistance of the LED chip itself, a certain amount of heat will be generated in the state of power on and illuminated, and the heat will gather around the LED chip for a long time. The consumption of the fluorescent powder is accelerated, so that the life of the LED is attenuate...

Problems solved by technology

The LED can convert electricity into light. Its structure is to place LED chips on a bracket, connect the positive and negative poles of the power supply through the bracket, and package the entire LED with a light-transmitting sheet made of epoxy resin fingers. Problem: Due to the certain resistance of the LED chip itself, a certain amount of heat will be generated in the state of power on and illuminated, and the heat will gather around the LED chip for a long time. The fluorescent powder accelerates the loss and attenuates the life of the LED; and the structure of the bracket is not conducive to the directional reflection of the light source, which wastes the light from the light source and reduces the light efficiency.
